Re: TOSHIBA 43u2963db - no picture, but sound (green/red flash)

So quick update regarding the unit; in short, it lives!!

The replacement mainboard didn't resolve the issue (worth a try for return postage), and there didn't appear to be anything wrong with the panel. However, I'd learned of a trick to help diagnose LCD faults where you'd unplug half the t-con board to see if there's a short on one side over the other. You could then chase down the individual clock pin and mask the offender with tape as the image is drawn from both sides; the whole screen should work...

Perfect, thanks!
Luckily I managed to find one mainboard with a matching model/board number, and importantly, the panel number also here in the UK. It won't arrive until sometime next week, but I'll be sure to update the thread with my finding, who knows, it may actually be useful to others.

Re: TOSHIBA 43u2963db - no picture, but sound (green/red flash)

Thanks Peter,
I've found (quite a few actually) replacement mainboards here in the UK also, but will need to confirm the panel P/N first. Would you happen to know where this is located? I'll probably have the time to pull the set apart again on the weekend.

In the meantime I'll see if Vestel will provide the correct firmware files, it'll probably be worth the ordeal of dealing with customer service to know that I won't unintentionally brick a replacement mainboard... ��

I've an issue with a set I've just received from a family member hoping to repair (model: TOSHIBA 43u2963db). It's seems to be a Vestel unit on the inside :'( ... There's sound, but no picture. I've pulled the panel, tested power running to all components (even past the t-board, well 3v on test pin 4_0...). I've also *tried* giving it a reflash, although I doubt this is an issue I can't seem to get it to enter the correct mode (hold ok on remote and then plug in with the USB inserted containing the necessary files). The TV will create a folder on the pen drive "DVR" when it powers up,...

Re: Toshiba 40L1333B blinking red/green power indicator

I've the same issue with a set I've just received from a family member hoping to repair (model: TOSHIBA 43u2963db). It's basically a crappy Vestel unit... There's sound, but no picture.

Hey,
Just posting so I can start a thread to help diagnose a problem. I've searched the forum (and elsewhere) to no avail.
