Question about Toshiba 51H93 51" Rear Projection HDTV

1 Answer

Will not turn on

My 51h93 Toshiba unit will not turn on either with the remote control or directly on the front button. Technician came to repair as part of warraty but boards came cracked and were returned but it took to long to get the new part that store gave me credit for the unit and I still kept the unit and would like to repair it but don't know what's the parts. I know there were two circuit boards that needed replacement, but don't know the part # to order them. Any help?

    TV won't turn on. I can see an orange light inside the rear case when I plug it in, and then it fades away

    Won't turn on. Reset button on front panel didn't work either as suggested in the manuel. I can hear something "click" when it is plugged in. Is God telling me I need to get a flat panel???

    I disconnected and moved my Toshiba 51H73 unit and now it will not turn on by the remote control or directly on the front control button. When I press the reset button I can hear a clicking sound.

    TV worked fine the day before. Next day TV would not come on by using power button or reset. Hear a clicking; then a sound like it is going to start; then nothing.

Toshiba Regza 32C3000A tv sound keeps droping out, the mute button when pressed on and then off brings it back on. seems as if the tv is auto muting itself?


Could be a contact piece of the MUTE button from your remote that is causing it.
Go out and Big Lots or Radio Shack to get a cheap universal remote control(big lots would be between $5-$10) Pick up the code for it,and when the tv happens again,your the OLD remote MUTE button to turn it back on and then put away this remote control and use the new universal remote control.
However,if the problem is coming from the manual MUTE button on the TV,you need a repair tech, to fix it!

Toshiba 51H93 won't turn on **HELP**


Good Day, jsilver05;
That's a very good TV, sorry you're having a problem. I have the same TV.
1. The blurring of the pic may be an indication of a convergence problem.
2. The surge protector is not a fail safe device, it will reduce damage to the TV but will not not 100% protect it.
It is possible that by turning the power off may damaged the already weaken convergence circuit, but more then likely some other electronic device failed.Like a voltage regulator, high voltage device,and etc.
At this point I would recommend that you call a factory authorized service dealer and them come out and give you an estimate, or you can e me if want troubleshoot TV if you have digital meter etc.
Good Luck, big IRISH, mmrkcar@yahoo.com.
