Celcus DLED39167FHD Power Board replacement problem	Can't Post

Hi,

Recently my Celcus 40'' TV (DLED39167FHD) went pop! Since I didn't want to fork out extravagant costs for repair, I opened it up to see if it was something I could do myself. Once inside I discovered that the power inverter PCB was blown, but since it is a separate board, I figured it would be fairly cheap to get a replacement board and swap it out.

I found numerous stockists of the board and ordered one. On receipt, I discovered that at some point there must have been a manufacturing revision and one of the connectors (which I assume goes off to the push button controls or the IR receiver or something) had been changed along the way. The old (faulty) board has a 6 pin in-line connector, while the new has a more compact connector, seemingly with less pins therefore I cannot connect it up and am a bit stuck.

I have since ordered a second board from a different supplier, only to find that this one is also the more compact connector. Now I have two boards that don't fit. Maybe I just need to swap out the connecting piece, but I don't know where to source one TBH.

If there's anyone that can help me find a way to get this TV working again, without any more financial cost, I'd be really appreciative.

Here's a pic of the offending difference.

Thanks in advance for anything you can suggest.

Push button/IR receiver should plug into the Main board. Your other two Power board connectors should be Mains power and power to the Main board.

What are the numbers off each board? I think you'll find that a part number(s) / revision number(s), version number(s) etc. is the difference. With only a small portion of boards shown in your photos, I can see there are a couple more additions / deletions. Proceed at your own risk.

Found better photos on another site. Those appear to be where the backlight LEDs plug in. Compare foil patterns on rear of both boards. If pattern is the same, you could swap the correct jack on original board to the replacement board.

As for part numbers, all those listed with retail suppliers only have a single reference number (17IPS20) and I've yet to identify any marked version/revision on the board (though I'm not really experienced enough to know what I'm looking for).

I don't think I'm capable enough (or confident enough) to try to swap out the jacks. Does that mean that I'm left with no other solution? The jack in question has just a short two wire section that connects to the relevant next part. Would it be feasible for me to try to get hold of a replacement for this? And how would I go about sourcing such a thing?

Thankyou for your help!

If necessary, I can take a few more pics and post them here later. Just tell me what you need to see.

Why is it so hard to get people to post ANY numbers (on PC boards themselves or stickers affixed to them) that may or may not be of any help fully identifying boards?
Try good clear pictures of those areas plus back side of each boards 'connector in question' areas so the individual foils can be seen. Check for numbers/stickers on rear of boards too. I should be capable enough to discern which are relevant. (You are getting the 'base' board number by the Vestel logo). Getting the exact replacement board would be the best way if you can't or won't swap out jacks (or hard-wire the two wires in question)(do you know how to solder or know anyone who can?). If you're not capable or confident with that, even IF a replacement LED strip can be located, YOU would NOT be capable/confident disassembling/reassembling the panel or swapping the PLUGS.
I suspect there are more discrepancies between the two boards. I can see from your original pictures that one board has a resistor above the connector in question and the other board is missing it altogether and that there MAY be a huge transformer missing on the replacement board (although that could just be the result of not having the exact same area shown / centered). I CAN make out the numbers off one sticker but not the complete number off the other. I CANNOT make out the location numbers of each part but right now that's NOT important.
From photos on another site that one sticker (other than an 8 character number along edge by a power plug) MAY be the only identifiers on boards' top side (they do NOT show any pix of back of board).

EDIT:
If the pcb to be replaced has a two pin connector at ref. CN500 an adaptor cable has to be ordered as the replacement pcb has a seven pin connector, CN501. Please order F326678.
