Re: Toshiba 55HT1U No Picture, No Sound



Finally got it. It was the other two master inverter boards. First I disconnected both the inverters and I got the faint pictures with flashlights. So I knew everything else is good. Connected the slaves and got the faint pictures. So I knew it was the master inverters....

Re: Toshiba 55HT1U No Picture, No Sound

I had the burnt connector between the two slave inverters. So I bought the two slave inverter board that were burnt out on Ebay and replaced them. I still do not have a picture. So now there are 3 more options, the main board, T-Con Board and the power supply. I can probably measure the voltages from the power supply board and test it. I can try the T-Con and the main board.
Anyone got this working? Could it be the LCD itself. Then it would be a waste to spend any more money on this.

Re: Toshiba 55HT1U No Picture, No Sound

Wow, I have the same exact problem. Called Toshiba and they confirmed the hidden warranty, but even that expired 6 mos ago. I am planning to buy the slave1 and slave2 boards from ebay and see if that fixes it. I have to figure out how to make that 14 pin jumper cable.

Anyone know what caused that cable to burnout. If it was just bad board, replacing it should get me going. If it was caused by a different board like T-Con, power supply or main board, not sure how to figure it out without burning this board again. Any ideas?...
