20 Most Recent Toshiba 57H93 57" Rear Projection HDTV Questions & Answers


If the set when first turned on has noise lines or distortion (left to right usually) but after several minutes they diminish and go away you have a bad HYPER board.


If this is the case let me know and I will advise you on options.

Toshiba model 57H93 worked perfectly last night. Turned off and went to bed. Turned on this morning, and nothing, it won't turn on. Checked all cords and cables, pushed reset button, and still won't turn on. What could cause this to happen?

Hello,

your TV is having a power problem. I would suggest you visit A TECH to fix the fault for you because I don't think this is what you can handle.

Take care.

Hello,

your TV is having a power problem. Its receiving power but it cannot transfer the current to the necessary part because a capacitor, diode, etc but have been faulty. Until these bad components are replaced, the TV might not come on.

If you know about TV repairers, I would suggest that you open the TV and read the power part/panel with a meter, detect the bad component and replace it. Take note that TV stores a lot of current that can shock, so leave the TV for a while before you open it.

If you don't know about TV repairers, take the TV to the nearest repairman to fix the fault for you.

I wish you good luck.

these sets use a magnetic relay to turn on after a while the metal contact pads on the switch burn (just like turn signal flashers in a car)
this causes the relay to click closed but open up again before the TV can start. the relay is on the power supply board it should be labeled RL1 on the board, it is a small black or, brown plastic cube usually located next to the power cord. If all fuses are good this is the problem.
unsolder and, replace the relay.

after a power surge if you dont have in on a surge protector it probably fried the main board in the tv so it wont work anymore..woudl probably be cheaper to buy a new tv than to try to repair the one you have now
