I have not gone there yet because papa Ron has not informed me to go there yet,,, plus, from all the research I have read and the danger's & hazards going into (service mode) I'm scared my legs will fall off and my eyes pop out, lol

Hoo-boy, Ron,,, You rode my butt one time bragging all about the pro skill's jts has with TV's. And now your gonna kick him down a level because I was explaining that you had not informed me to do so. Glad I don't watch TV, it's just a project and learning experience to me,, there is no skin off me to roll that big taking up space thing to the curb tomorrow, I didn't buy it, was my ex's, lol

Misfire;.....

Allow me to clarify my comments so you & everyone will understand...

jts1927's skills are NOT being criticized here...
He is STILL a FINE tech...
I fail to see where he's been "kicked" down a level..

A question for you;=>..

Quote

question? This TV offers error codes in service mode, or is that not anything?

How did you find that out ???

I thought we (that being YOU & I) were working together to save that TV...
IF you want to roll it to the curb , be my guest...
It's certainly NO skin off my nose either , after all , it's YOUR TV & NOT mine...
IF there's any criticism directed here , open your eyes & you'll see who it's aimed at..
You comes to my mind...
Without getting into a full out war , suffice it to say that you have a tendency to skip over my questions , not follow parts of my advice & jump around without any concern for complications with the repairs...

Consider your butt "ridden"...

the blue arrows point to tape removed, the red arrows point to tape that was sticky on both sides but not, repeat (NOT) removed or moved in any way but was marked indicated by black marks. http://i776.photobucket.com/albums/yy45/Misfire_photo/CAM00584_1.jpg the second foto can see the tape was not removed and marked for relocation of white plastic part the coils were in held by clamp. (at bottom of screen) http://i776.photobucket.com/albums/yy45/Misfire_photo/CAM00591.jpg now if there is suppose to be anymore tape on glass tube? I have no idea? and as far as a foto of inside of high voltage splitter?? I can barley see inside with my eye's much less take a picture,,, I do not own a bore-a-scope. I have got it to stop buzzing (makes no noise now) so I let it go, what more could I do with it? its working. is this considered a connector?http://i776.photobucket.com/albums/yy45/Misfire_photo/CAM00605.jpg the wires go in the tubes and held in place with little metal tabs at the bottom.

First things first....

PLEASE accept my SINCERE APOLOGY....

On my monitor this pix shows a bare neck CRT with a piece of tape at the bottom...
http://i776.photobucket.com/...e_photo/CAM00591.jpg
I presumed that that tape was for the SVM module...
It is VERY hard for me to see the markings on that tape on this monitor...
So you ARE CORRECT that the yoke tape was NOT REMOVED !!..
I APOLOGIZE...

Please also keep in mind that there are some people who come here & give misinformation (better known as lies) regarding repairs etc...
Since I don't know you from Adam , it's easy to jump to that conclusion..
NOT an excuse...
But a reason...
I was wrong in your case...

That said...

We have some housekeeping to do....
1)..
Please check the following;...
On the convergence board , check the wiring from J19301 , J19302 & J19303 to the Red , Green & Blue yokes respectively...
Those should be along the left side of the convergence panel..
2)..
On the convergence board , check the wiring from J19102 , J19103 & J19104 to the Blue , Green & Red yokes respectively..
Those should be at the top right center of the convergence board...

3)..

In post #69 , I asked the following;=>

Quote

Do the other wires have a copper colored (or another color) connector with the wire coming thru the center of it & soldered or spot welded in place ??...

What I want to know is:..
Do ALL the other wires that go into the HV Splitter have the SAME ends as the wire from the flyback ???...

all gun connectors are in their proper location on convergence board,,, and I don't really understand about a connector for high voltage wires from fly-back? maybe this picture can explain,,, only removed them from the splitter when you had asked to check it for burn or carbon tracking.

Misfire;...

Let me re-phrase the question;...
Do ALL the wires that came out of the HV Splitter look like one the below with the ends the SAME as whats in the red circle ???..
[URL=http://s772.photobucket.com/user/RonMa/media/HV%20Fly%20Wire%20End_zpszhbz2mcv.jpg.html]

Just to verify & make clear;...
ALL the Red wiring from the chassis & convergence board go to the Red yoke...
All the Green wiring from the chassis & convergence board go to the Green yoke...
All the Blue wiring from the chassis & convergence board go to the Blue yoke...

Now I'm going to need some pix..
Cover the lens on the GREEN CRT with some cardboard or newspaper or ??? so it stops the green from showing up on the screen..
Tale a pix of the screen...
Remove the cover from the GREEN CRT & cover the RED & BLUE CRTs in the same manner & take another screen pix...
Then uncover all CRTs...

With the TV off,
Disconnect the connector at J19302 / P19301...
That's the green convergence on the convergence board...
It will be the center one on the left side of the board...
Turn the TV on..
Take a pix of the screen..
Turn the TV off...
Plug in the green connector (J19302 / P19301)...
Unplug BOTH the Red & Blue convergence yoke connections (J19301 / P19300 (RED) & J19303 / J19302 (BLUE)..
Turn the TV on..
Take a pix of the screen..
Turn the TV off...
You should have 4 pix of misconvergence..
Please post links to pix...

THANKS...

Not sure what country you're in , but IF you are in the USA , Happy Labor Day... Smile

Yessir, all wires out of the splitter look just like that one in foto, and both J and p connectors in proper location. here's foto of green covered,http://i776.photobucket.com/albums/yy45/Misfire_photo/CAM00627.jpg and here is foto of red and blue both covered.http://i776.photobucket.com/albums/yy45/Misfire_photo/CAM00628.jpg
Having a problem with last bit of instructions, if I unplug any of the (P) connectors the set will come on but none of the guns lite up, have no picture at all. and yessir I am a American and a happy do nothing day to you also, lol

Misfire;....

I won't need those other 2 pix...
I've seen enough to know that you have lost all convergence , even the green....

Let's start with the Convergence power supply...
On the convergence board as shown in post #26 , in the upper left corner is connector J19304...
Disconnect that , turn the TV on & see IF the results are the SAME as before...
IF they are , I repeat , IF THEY ARE , take your handy-dandy meter & take DC voltage readings from all pins...
It should be easy to take the readings from the connector that goes to the power supply..
Be CAREFUL so you do NOT short ANY pins together while you are taking a reading..
That may cause damage to the power supply..
Pin #3 is chassis ground...
You readings on pins 1 & 2 will be negative readings , so set your meter accordingly or use your meter's red "+" lead to pin #3...
The readings on pins 4 , 5 & 6 will be positive readings so have the "-" negative meter lead hooked up to pin #3...
Post ALL readings;=>..
Pin #1= ??
Pin #2=??
Pin #3 is chassis ground & should read 0.0 volts...
Pin #4 =??
Pin #5 = ??
Pin #6 = ??

I hope to be online for awhile today..
If you should reply soon , perhaps we can get an answer today concerning this problem ..
If not , we'll just continue as we have...

OK, with TV on and P19304 unplugged using terminal 3 also with chassi for grnd, I got 7.2V on last term #6, that's it. nothing on the rest. Is J19700 ac or dc going in? I have 120VAC on mine going in. wonder if the STK took a hit? I don't believe it to be a real sony or sanyo product.

I think measuring at J19701 may be better. You need to determine if any/all diodes connected to T19701 are outputting anything.
(With J19304 connector unplugged, If you are measuring at J19304 pins on the convergence board, you shouldn't get any readings ... If you are measuring at the pins inside the disconnected plug, then you should, if is working, get some readings.

We went through this process in the original thread (remember 'there ain't No 10s').

Misfire;....

jts1957 is just fine....
NO problem....(yet)...
His advice IS GOOD...

BEFORE you do anything else , I'd like you to CAREFULLY remove the Convergence Power Supply Board from the TV...
Reason is that you said earlier that the Convergence Menu was coming & going intermittently...

Temporarily SHORT OUT C19702 (200 mfd @ 200v) to discharge it..
IF it is fully charged , you will see a large spark & hear a loud snap/crackle or POP !!!
It may be a large cap in a metal can....

There MAY be bad solder connection(s) on that board...
Check the solder side of the board for bad or loose connections , especially at the IC , U19700...
Also check the connections at the transformer T19701...
IF any even look suspicious , re-solder those connections..
Check & see IF ANY parts look overheated OR BURNT...
PLEASE post findings...
THANKS...
Re-install Power Supply in the TV..
Just for the hell of it see if the convergence returned... Shocked

IF not.......
You may have not gotten the readings as I had hoped from the J19304 plug....
Try it his way at the Power Supply Board (J19701) & re-post the readings...
Again , use care NOT to short any of the pins together...

J19700 is the AC input for that power supply ONLY ...
There IS a possibility that the IC did take a hit , but , we haven't got there yet...

well no snap,crackle or pop out of C19702, I got little spark out of one of other smaller caps, don't see any cold solder joint breaks using a magnify lamp and its the same with the voltage on one pin, number 6 after plugging power sup back in, I measured at board J19701, and plugged rainbow connector in to power supply j19701 and checked at other end unplugged,,, same thing.

Nope !!!...

...

Misfire;....

I can't stress enough that you MUST use pin #3 for ground when you take those readings at J19701...
DID YOU ???...
Go to the AC in connector J19700 verify that you ARE getting 110 AC volts...
IF that's there , hook your "+" meter lead to the "+" side of C19702 & the "-" lead to the "-" side of that cap & see if you get ~145-160 vdc...
TV just has to be plugged in for these readings..
The convergence Power Supply is ON 24/7 when the TV is plugged in to 110 AC...
Please post results...

jts1957 IS correct !!!...
Please go back & re-read the voltage at C19702 & have your meter set on 200 OR 600 VDC...
VDC stands for Volts Direct Current...
The reading most likely will be different...
Probably around ~145-160 VDC
