Sharp 70" LC-70TQ15U Won't turn on.

[Todd S.]

Hello,

I'm trouble shooting this unit and could use some help. Here is what I have found so far:

*Standby light is on.
*Back panel removed.
*No signs of heat or damage on any boards or components.
*A tiny led on main board is lit when plugged in.

Pressing power button does nothing. No clicks, nothing on screen or any sign of life.

Any advice on what I could do from this point is greatly appreciated.

Thanks in advance,

Todd

Interesting because I have the same TV in the garage that I put in there because it did the exact same thing as yours. Must be something about this model.

I hope we can find a fix.

Hope we get a response. I'm not charging for the repair. Working on this TV for a friend

search on the sharp 70 ... lots of posts on how to check and potentially "save" the set.

Does anyone know of any other web site that can help me with my issue?

If you can you supply photo's of the rear of the set showing circuit boards and interconnections and also power supply voltage readings you have taken, perhaps someone on this forum could assist.
