Ron...do you remember the B12083477 rectangular board shopjimmy carried that was out of stock (in fact, every damn board they carry for my TV model is out of stock, it looks like, for good.) Anyway, ebay has a used one for the most moronic price right now. If I were a gambler I'd say that was the one that originally came in my TV. The price though...no way I'm paying that!! Even though it says "make offer"

I sat on the floor tonight trying to get my TV to come on for an hour and 40 minutes. That isn't counting how long it took me to get my ass off the floor afterward!! I need a replacement part in the mail ASAP.

BOY , OH , BOY !!!
It seems like the current breed of TV manufacturers are doing their best to PISS off TV Techs to NOT fix their TVs & make the customers buy another POS from them !!!

THANKS for the GREAT pix !!!
You did a FANTASTIC job !!!

However , we have some unfinished business to take care of;=>..

Let's start with the >>> back cover <<< ..
Go to page 13 , on that page is a pix of the connections that are for inputs & outputs..
I need to see the ones on the upper right side extension of the "L"...
Namely , connections 7 , 8 , 9 & 10...
>>> Take the pix at an angle that shows whether or not those openings are there.. <<<

My intentions are to see IF Sceptre ACTUALLY has holes for the "L" shaped board that was allegedly the original board !!!..

To complicate matters , your TV appears to have a different
board than what is shown in the user guide !!!
Let's start here;=>.

In the User Guide on page 13..
The connections from left to right are;=>..
1)..SPDIF (Digital Audio) & is the SAME as what's in your TV..
2)..IN the user Guide ==>Audio In ...
Is NOT what you have in your TV..
You have the RF antenna/coax/cable fitting INSTEAD !!!
3).IN the user Guide ==>RF antenna/coax/cable fitting..
Instead in your TV you have the VGA Connector !!!
4)..IN the user Guide ==>VGA connector..
Instead in your TV you have an unknown connector that
may be a headphone jack !!!
5)..IN the user Guide ==>YPbPr
On your TV you have a series of what appears to be 3 HDMI ports & one USB port ...
That's just for starters !!!

On the other panel pix , this one;=>.
http://imagizer.imageshack.us/a/img922/787/9B9Rw6.jpg
There's NO resemblance to what the User Guide shows...
Since NEARLY ALL of the connectors are NOT the SAME as what the User Guide shows , I'd appreciate pix of the back cover showing the openings for ALL the accessories , items 1-6 & 7-10..
Also take a pix of the labeling for those connections..
THANK YOU VERY MUCH !!!
It looks like when you had the TV repaired by Sceptre (?) , the tech(?) RE-ENGINEERED/REDESIGNED the TV with some dramatic differences than what was ORIGINALLY there !!!

You have your frustration turning on the TV !!!
I have been frustrated trying to find a board FOR YOU that WILL work , IS RIGHT for your TV & does NOT cost an arm &/or a leg !!!
So we BOTH have our frustrations !!!!
I realize more than you think about ASAP !!!
However I or you did NOT create this & produce the consequences that came from a questionable previous repair...
Try to hang in there & I or someone else should get to the bottom of this..
As for;=>..

That's WWWAAAYYY overpriced !!!

�This board was removed from a TV with a cracked screen and is in very good condition ready to ship.

I lost count on how MANY TVs are out there with "CRACKED SCREENS" on eBay !!!..
I take that with a grain of salt !!!..
I suggest you be patient till we/you resolve the issue of WHICH style board IS the correct one for your TV...

Quote

If I were a gambler I'd say that was the one that originally came in my TV.

You'd probably lose cuz de User Manual shows that is the WRONG board !!!

BTW:...
I thought from the VERY beginning that this was GOING to be EASY to help you.
What a SHOCK !!

PS:...
I did a Google search for "B12083477" & mostly came up with the $83 eBay board or more $s , a "Repair Service" or Out of Stock , none of which is going to help you !!!

Re: [Ron.M] Sceptre 42" TV, needs mainboard, having trouble finding it [In reply to]	Can't Post

So I'm starting to think my TV was shipped with the wrong manual, and I'll tell you why.

Remember me saying my remote was always a different one than the one pictured?

Also, I recall my HDMI and USB connections always being on the bottom of the TV, never on the side, even before they swapped the board the first time. I remember it being a complete bitch to get to.

I don't remember what the board looked like when he replaced it, but I do recall him ONLY replacing the board, and not any of the stickers that say what the connectors are, which BTW do coincide with what the connectors are, or the metal I/O plates, which surely would have had to be changed had my board been changed so drastically. I'm not sure if you would call it an I/O plate in your profession, but in computer repair, that's what they're called.

Re: [Ron.M] Sceptre 42" TV, needs mainboard, having trouble finding it [In reply to]	Can't Post

Here is yet another UPDATE! My suspicions about being given an incorrect manual have been confirmed! Just for shits and giggles, I decided to have a poke around in the original box, which surprisingly, I still had in my attic. I sent my son up for it, and he brought it down. Inside there was a very small box that I had never opened, and inside it was a plastic baggie, a second manual, a phillips head screw driver, and a wipe for the screen.
http://imageshack.com/...g921/9236/yDGoyt.jpg

I had a look around in it, and it looks like the proper manual, plus the remote is the right one that came with my TV. This tiny box was at the BOTTOM of the box, wedged between 2 foam inserts, and I never noticed it before. The incorrect manual was sitting on the top of the TV, so I didn't ever think to check for a second manual, I just assumed they had sent me the correct one, especially since the model numbers lined up.

I am now convinced the rectangular board is the board that I need, either that or that stupid replacement board for the 32" TV they put in when they did the repair 2 1/2 years ago. This is the photo of the inside of the manual, which lines up with the photos I gave you yesterday.
http://imageshack.com/...g923/5838/a8vCLf.jpg

Too bad the boards I've found that look like the ones I need have always been SO EXPENSIVE. I believe what I need is a T.RSC8.10B 12305 model number LC320WXC-SBV2 (the replacement board they put into my TV that I've been running in it for the past 2 1/2 years) or the original board (I think) the T.RSC8.10B 12305 model number B12083477. There is probably another board or two that would be compatible, but I just don't know what they might be unless I were to talk to someone who had repaired one of these EXACT TV's before, with the same rectangular boards. And considering the general consensus seems to be to throw it away and get a Sony, that doesn't seem plausible at this juncture.

So what do you think now, Ron?

So sorry to hear of your loss Ron. I've lost 3 people I loved a lot within the last year and it's hard when something you love leaves you. I have a couple cats of my own, and I've taken on the cats of my mother and my niece when they passed, so we have 6 in all, and I'd be devastated to lose them. A couple have touched my heart more than others, but animals can be great companions and can hurt as much as losing a person when they go. My thoughts are with you today. Take however long you need.

GeekyG1rl;....

Brownie passed away early Monday AM...
When I woke up , she was laying on the floor near where I sleep...
I called her name & she did not move..
She usually is awake before I am , and ready to go out..
I went to her side & that's when I discovered she died during the
night in her sleep...
I took her to my Vet to have her cremated..
This morning when I got up , I burst into tears..
No Brownie wagging her tail wanting to go out...
Just an empty house with no joy left..
It will really tear me apart when I go later this week to pick up her ashes..
Can NOT figure out WHY she died !!!..
She was improving nicely till Sunday evening..
She ate OK , she did her business (#1 & #2) OK , she took her meds OK..
At around 10:00 PM , she started to dry heave randomly..
She settled down around 11:00 PM & we both went to sleep ...
She never woke up...
I had her for 10 1/2 years..
When I got her I estimate she was about 2 years old..
I LOVE her like a daughter ...
She WILL be sorely & immensely missed...
She was my 7th dog..
The other 6 lasted 14 to 18 years before old age caught up with them..
It DOESN'T get any easier...

That said , it's best for me to immerse myself in TV repairs & ??? to keep my mind occupied...

Back to your TV;=>..
Did a Google search using "T.RSC8.10B 12305 B12083477"
The results ;=>..
https://www.google.com/...+12305++B12083477%22
SLIM pickens for that board..
I ran into this before we got sidetracked on which style board is the CORRECT one for your TV..

The ONLY boards that I could find that ARE in stock & priced slightly less that your right arm are at eBay;=>..
Those that are reasonably priced are OUT OF STOCK !!!
Here;=>.
http://www.ebay.com/...CAds=&rmvSB=true
Here are some possibilities ;=>..
http://www.ebay.com/...7:g:-hAAAOSw7KJXDqEu
This is the one you looked at before & is priced at $83.95 w free shipping...
For that price they SHOULD hand deliver it WITH a kiss ...
That is the ONLY board that has your EXACT numbers...
There are a lot of boards that look like yours , but , I don't think they would work in your TV.. DAMN !!!.. Mad

More specific listings on eBay;=>..
http://www.ebay.com/...2083477&_sacat=0
You can see that the $83 board at the top of the list is the ONLY board that matches yours..
Again there are a lot of similar boards , but , the numbers do NOT match...
In short , it looks like you have ONLY one choice...
Try to Make an offer around $50 or so & see if they nibble...
Keep in mind that you only have 3 chances before you offers will stop & you either have a deal OR you'll have to pay FULL price..
GOOD LUCK...

Have a GREAT day & week... Smile

Hello Rachel. ... I haven't read through all the replies (too much reading for me lol)

Your main signal board may be fine. Not sure if anyone has suggested this next test or not....

Try unplugging the tact switches on the TV that control the power on/off, volume up/down, channel up/down etc. these tact switches go bad even if they are never used, they become conductive internally or even partially conductive. When this happens it confuses the microprocessor & gives it all sorts of unwanted commands which in turn can cause every symptom your TV is experiencing.

With the buttons unplugged you can only use the remote control.

Also if the infrared remote control sensor is mounted to the same board as the tact switches this test may not work because you will not have remote control functions at that point either, a way around that would be to desolder the tact switches.

If that works you'll have your TV back up & running for free.

Almost the identical thing happened to my mother, except she woke up complaining of not being able to breathe and passed away in the ambulance on the way to the hospital. She was just 59. It's hard to immerse yourself in things to keep your mind off things that hurt when you're a disabled person like me, one of my hobbies has been to watch British TV (it's a lot funnier than American TV. I watch the old stuff mainly, which is very good), but having this issue with my TV that I've been having has made that hard. I need more hobbies, but with physical limitations they're very hard to find.

I will keep on the lookout for another board. Maybe I'll get lucky and another will pop up for sale.

So, you don't recommend replacing it with the board they put in during the last repair?

Re: [Repair man] Sceptre 42" TV, needs mainboard, having trouble finding it [In reply to]	Can't Post

Thanks for the tip! I'll have to *groan* ask for help removing the TV from the wall for a third time, remove the back and check to see if the remote sensor is on the same plug. To me though, it would seem that if it were going to malfunction, or had a malfunction, it might also do it while the TV is on and functioning properly, and give me some sort of trouble. All I know is what I know from being a microcomputer specialist, which is a bit different than a TV repairperson. Every issue I have ever had is getting the thing to turn on. Once turned on, it worked just fine, until powered down again.

The board I just tried to track down is an ORIGINAL Board ???
That's the "T.RSC8.10B 12305 model number B12083477"
Right ???
The subbed board is"T.RSC8.10B 12305 LC320WXC-SBV2" ???
Right ???

Going back to post #3...
Please take a second look at this board...

" T.RSC8.10B 12305" is on that board !!!..
"LC320WXC-SBV2" is on that board!!!..
I suspect that that board may work !!!..
Why did we/I pass over this board ???
BTW , it is STILL available & you get the power supply board also !!!
I'd suggest you send them a message asking them IF they know IF that Main Board WILL work in your model TV...
Let us know what you get for a reply...

Re: [Ron.M] Sceptre 42" TV, needs mainboard, having trouble finding it [In reply to]	Can't Post

Two things. The power board and main board combo you posted is the same one that we determined the guy to be a flake, remember?

One more things, and I feel like a huge dumbass for this. Are you familiar with Facebook at all? I do have a point. There's an app called "On This Day" on Facebook where you can view all the things you were bitching about 1,2,3,4,5 etc. years ago. Guess what I was bitching about exactly 1 year ago today? You guessed it! My TV set!!

"About 2 years ago I bought a 42" TV from Walmart, and of course I paid the extra bucks for the 3-year protection plan. Within the first year, the power board went out on the TV, which was covered by the manufacturer. They sent a technician out to my house and replaced the board, no big deal. "

Ron, they replaced my POWER BOARD 2 1/2 years ago, not my main board. That leaves me with a few unanswered questions. WHY is there a main board for a 32" TV inside my 42" TV, direct from the factory? And I was sure it needed a new main board BECAUSE it was behaving the same as it was before, except for one thing. Before, you could turn it off with the button or the remote. Now, you have to unplug it to get it to turn off.

I really shouldn't be doing all the second-guessing that I'm doing right now. I'm a licensed microcomputer specialist, and main boards and power boards are pretty close in TV's and computers....but somehow I am. My microcomputer training tells me main board. My brain tells me "You work on computers and you don't know shit about TV's!!" *facepalm*

( I had a nagging thought from early on that that could be a possibility !!!..)
OK , here we go !!!
NOW we need to determine IF the power board OR the Main Board is causing your problem !!!!
Here's the deal , if you qualify ....
Do you have a DVM & how to use it ???
Do you know basic electronics , caps & resistor functions ???
VERY IMPORTYANT question:=>..
ARE you WILLING to take the TV OFF the wall , remove the back cover , take some voltage measurements (EASY ones) & leave it OFF the wall in a SAFE manner so that your cats will NOT harm it & you can still use it while ongoing tests & readings are done ???
Otherwise , this is turning into an Easter Egg hunt !!
The guesswork must stop soon, OK ???
OR SKIP ALL THE ABOVE & GO FOR THE JUGULAR & find a Power supply Board for YOUR model TV ???

WHY is there a main board for a 32" TV inside my 42" TV, direct from the factory?

I have NO clue !!!..
You'll have to ask the CHINESE that question & hope for a sensible answer !!.. Unimpressed

BTW;...
Those power supply boards are MUCH cheaper than the Main Boards (Duh!!)...
ALL we/I need is the number OFF the Power Supply Board IN your TV..
So , that means the TV comes OFF the wall again...
I think I see a light at the end of the tunnel , I HOPE it's NOT a train !!!.. Wink

Re: [Ron.M] Sceptre 42" TV, needs mainboard, having trouble finding it [In reply to]	Can't Post

Ron, you'd be interested to know, before I even contacted the forum I took the back off and did tests with the voltmeter on the power board. Everything read the way it was supposed to, ie: the board is marked and my voltmeter read the same at every wire going into and out of the power board.

That's why I determined that it was the main board that needed replaced. the second guessing is because TV repair is not my area of expertise. They do teach basic electronics (such as voltmeter reading and soldering) when you take IT classes, or at least they did 17 years ago. Also, every repair video I have watched leads you to believe with LCD's if the standby light is working, its generally not the power board.

But, power boards ARE considerably cheaper than main boards.

GeekyG1rl;....

Ok , that's good to know that you know your way around a DVM etc...
LCD/LED Power supplies are not necessarily good even if the standby light is working as you said..
My ex-landlord brought me a 55" Samsung that would be stubborn to get on...
The power supply in that TV (& a slew of Samsung TVs) had bad lytic caps in the power supply secondaries ..

In those cases , voltages are taken with the TV off & a new set of voltages taken after the power button on the TV is pressed ONCE..

In the pix below;..
There are 2 bunches of wiring...
One of them is the power for the Main Board & the other goes off to never neverland !!!
I'm guessing that the wiring in red goes to the Main Board..
I'd like you to reconsider retaking some voltages on that harness IF you are willing to do so..
The results most likely would determine which board is at fault...
The wiring bunch I'm looking for has 5 vdc Stby , possibly 12 vdc + other supplies & the MOST important one is PWR ON !!
Are you up for this ???...

NOT necessarily ...
I'm beginning to think that with the pain you are suffering from & the meds I presume you are taking for that pain , that your thinking may be a bit cloudy..
NO OFFENSE !!!

What IS needed here IS a definitive decision as to WHICH board IS causing this problem !!!..
We've been bouncing back & forth between different Main Boards & now recently the Power Supply Board..
As a 50+ year analog TV tech , I'm NOT fond of guesswork !!!..
A simple test WILL give us the answer as to what's going on here...
IF you refuse OR can not get the test done , then I'd suggest you call in a TV repairman in your area..
I can & WILL give you DETAILED instructions as to how to get this done...

I'm not sure that you have..
The Power supply needs a turn on voltage..
Then there's the secondary voltages that need to be there for the Main Board & other boards to function..
ALL the secondary voltages MUST be up & running at their proper voltages..

I'm in pain management, but take no narcotic pain medications, so my mind is the one thing that remains unaffected in all this. I'm raising children alone, I have standards of living I must abide to, and have to remain unclouded in everything.

Every time I've used the volt meter (and had the TV apart) I've had my friends husband here with me, obviously, and all the readings made were seen by him. Actually most of them done by him because it was a sort of "show me how to use that thing". He has a desk job, and thinks electronics are cool.

Tell me what to do, but I assure you, the turn on voltages is what I checked for, and they were spot-on. Tell me what other voltages I need, and I will get them this weekend.

I wish you BETTER health & a QUICK , FULL recovery..

I need to have these readings done this way...
On one of the connectors shown by a green circle & a red circle , you should find a pin marked PWR or PWR ON or something to that effect...
With the TV off & plugged in , take a reading on that pin...
Write it down..
Find & take readings on all the Power Supply DC output pins..
I know what they'll read , but , I need confirmation that the Power Supply IS OFF...
With the TV OFF please take all those readings & write them down..
Press the Power ON button ON the TV ONLY ONE TIME...
Re-take all the previous readings & write them down..
IF it is the SAME reading , go to battle mode & keep pushing the Power on button till the TV turns ON...
Take those reading again & write them down..
You should now have a fairly good sized list of voltages..
Sort them out for a PWR OFF column & a PWR ON column..
Do the same with the Power Supply output voltages..

THANK you VERY much for your co-operation & patience...
Please post ALL readings when you can...

I'd suggest you print out this post so you can have it handy while this is being done...

I'm NOT rushing you for these readings..
But , I'll be checking regularly tomorrow (Sun) . to see if you are there..
If not , no worries ..

Later..Ron.M... Cool

Re: [Ron.M] Sceptre 42" TV, needs mainboard, having trouble finding it [In reply to]	Can't Post

Ron,
Wanted to let you know I've not been able to do anything involving my TV yet. Threw my back out and had to visit the ER and have been out of service ever since. Thought I'd let you know, I intend to, just obviously unable at this juncture. Doesn't matter anyway because even if I distinguish which part is bad I couldn't afford it right now anyway. Beginning of the month is coming, I've been unwell a great deal and unable to find enough jobs for the monthly bills so a part for the TV will have to be put on the back burner for now.

I'll let you know when I have those readings.

Re: [Ron.M] Sceptre 42" TV, needs mainboard, having trouble finding it [In reply to]	Can't Post

Well it's been a little over 3 months but I'm back. There has been just so much going on, and I've been bedridden for the most part of it. My grandfather has colon cancer, and I'm just sitting here waiting for the phone to ring with the inevitable news, and hoping when that times comes I can scrape up enough to make it a couple states south to pay my respects to him. I have my SSD court hearing coming up in a few weeks too so I've been busily preparing for that as well. Hope all is well with everyone here.

Here's my issue. I'm moving. Well, I'm not moving me, other people are, obviously, since I'm in bed much of the time, but there's been a lot of packing going on. I really want to order a new part for the TV to put into it when we get into the new place, because quite frankly, this tiny TV is driving me nuts!! The big one is packed in storage, and my voltmeter broke.

If you had to give the BEST GUESS, and of course I'm not holding you to anything, what do you think is wrong with the TV, the mainboard or the powerboard? AND....remember how the mainboard that is in my TV is for a TV that ISN'T the correct model? Well, I'm having trouble finding it, because I need an L shaped board, and all the ones that fit the model number that came off the board that I wrote down (LC320WXC-SBV2-T.RSC8.10B. 12305) ARE NOT L SHAPED!!! So I guess my question is, would a board for the X425-BV FHD I would find on a site like ShopJimmy work, since it was made for my model? There are a few of them. I'm just so confused. I'm just hoping the problem is the damn power board. It's cheaper and I have an accurate model number for it!

As always, any help provided is so very much appreciated!!

GeekyG1rl;.....

I'm really glad to see that you are alive , but , I had hoped you'd be well by now...
Please get WELL SOON !!!

Sorry to hear about your grandfather...
Must be an advanced case of colon cancer...
Most colon cancers are cured or treated successfully if caught early..

We STILL haven't determined which board is the problem ...
The Power Board or the Main Board !!!

When you get moved in & the TV is out of storage we have a test to do...
You will need a working voltmeter & the friend you had before to do the test...

When you are settled in & ready to go with the test , PLEASE post back here & I'll give you the info on the test..
Then we can order the CORRECT board...
OK ???

Try to be well...

Later..Ron.M... Cool
