Re: Toshiba 32L1350UD

Quick reply: new board arrived, now I get the green light when plugged in, LED backight turns on, is properly detected by a computer through VGA input, but image stays black. Nothing is displayed. The only difference is the old board had a half-size LVDS plug, the new one a full-width one.

Advice?

Not sure, do the numbers on the white sticker of the new board match the sticker numbers on the old board?

Re: Toshiba 32L1350UD

That's a tough one as there are two white stickers, plus the PCB:

The original reads: 461C5Y51L92 Rev:1D RM32T
The replacement reads: 461C5Y51L81 Rev:1B RM39T

The other white sticker reads, on the original PCB:
431C5Y51L92 REV:1D
On the replacement:
431C5Y51L81 REV:1B

Both PCB have the same serigraphied number:
SRI32T VTV-L32615 REV:1A

Not strictly identical, but many mass-produced devices do vary slightly from one batch to another…

Many manufacturers also have a generic PCB they stuff differently depending on the screen and model version. 431C5Y51L81 is one of the numbers on several Toshiba boards from 29" to 50".

What is the full service code number? it's on the back cover by the model number and what is the panel number? Should be on the back chassis somewhere on a sticker.

I don't know if you have a mismatch mainboard or not, you could try a firmware update/pair, the closest I see is this BUT I don't know if it will work on your tv. Could try contacting them and ask or maybe someone here has tried it on their tv and can advise:

Does Toshiba usually answers questions when a replacement part is replaced by a non-professional? There's no 32L1350UD unfortunately

Re: Toshiba 32L1350UD

An update: turns out the board was mismatched. My mistake as I didn't pay attention to get the exact same number.

New board appears to bw working fine, now waiting for the remote control to come in, since most functions cannot be accessed without it.
