So it is not being turned on.
You can do a mod: Solder a jumper from pins 1-3 to pins 5-8.

This will disable the t-con power cut-off and leave the t-con on all the time, perhaps in standby too. It will use more power in standby mode but should otherwise work OK.

Re: toshiba 37av500u

ok so that is the part thats bad?

Re: toshiba 37av500u

No, the part which is bad is whatever is switching it on and off which will be buried somewhere on the main board. The part is correctly switched off. Doing the jumper will show if the main board has other faults.

Re: toshiba 37av500u

do you have any examples of this mod? thanks

Re: toshiba 37av500u

No, but it is simple. Just a wire from the group 1-3 to 5-8, like a short circuit. It has been done on this forum before with mixed success. Often it reveals that the main board has issues with the processor. But it has worked once before for me.

Re: toshiba 37av500u

ok, sorry man , all i have to do is short any pin 1-3 to any pin 5-8 just one jumper?

Re: toshiba 37av500u

Yes, just a piece of wire. Lay one end across 1-3, apply solder. Lay the other end across 5-8, apply solder.

Re: toshiba 37av500u

Check your soldering is good. Don't short to pin 5. You may have PSU problem.
