No power have 57" toshiba (model #57H93) will not power up after storm-caused power outage. no problems with all other equipment around it. possible causes/fixes?

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.

I had the same problem and called sears they only chare $99 to come out free estimate. it was a circuit board had to be resoldered and it works great

This set uses up to 7 fuses, some are normal glass and others are what are called pico fuses--see attached photo.

Check with set unplugged, just like any fuse.

If any are blown set will detect no voltage and set will not come on.

Let me know what you find, allow the site here is supposed to notify me by email if you comment, but major problems with that right now.

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?

Ur DM power board is dead,must be replaced.Try this
website for the board.Tv repair World.com.

Check cables.

hello yes there are fuses. the main one is located in the power supply it glass type it might be black where it has shorted if you replace it and it blows again then you have a dead short in the power supply good luck. ps on the main there are wickman fuses these are solder in to the board

shaun

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

I have the same exact problem that started today. Any ideas.

Protect screen Part # 23311038.......117.30

Fresnel screen ( inside ) # 23311014 ...65.47

Lenticular screen ( middle) # 23311128....81.96

You should only need the protector screen......T.
