Default Anyone have experience repairing LCD/LED TVs?

This was taken out by lightning and I thought I would replace the power board and be done. Well, now I have replaced the 3 boards you see here:

Here is the model

Have you used a voltmeter, started where power comes in and worked your way to the boards? Have you used your nose? Check continuity on the wiring?

Lightning took out a bunch of stuff last summer. The white power light comes on the front, but no screen. There is an LED on the tuner board that comes on when the remote is used. Not sure what else.

No, it just isn't very old and thought I could swap a board and be good. Now, I'm in deep and hate to dump it!

was one of the boards you replaced the power supply board?

Here is a link that might help you out. See post 9 for the service manual. You will have to join the site however.

dude thats an ol 60HZ sharp - the 300 + labor you just threw at it might not be worth it.

New ones can be had for around 600-800 with better specs.......

It will cost as much to repair as a new one. Invest in a surge protector.

Wow thanks. Just made major headway! Using a flashlight I do have a picture. Now just have to figure what to do about the LED backlighting!

Mac if you have a picture with the flashlight, I would join and start a new post with your symptoms, there are a bunch of great guys that might be able to help you there. Good luck.

You do have a backlight error. I will send you a PM that tells you how to defeat the shutdown circuit temporarily to see what is wrong with the set.

In order to repair you will have to dissasemble the panel, which is not something that is easy. It's VERY easy to crack the lcd panel when you have it out.

My mother in law's TV went out and it was the power supply board. She had the TV mounted above a fireplace and when the fireplace is burning it produces to much heat to the TV and burned out the power supply. She can't use the fireplace and watch TV at the same time.

If the TV had a simple failure, you have the right approach. As it was taken out by lightening, you would have been better off to chuck it.

Old CRT TV's were very repairable, and it was rare the CRT, (the most expensive part), failed.

Now back to the present. An LED is a semiconductor, just like the other electronics that were taken out by the lightening. Good luck.

Yeah, I'm about finished with it. I figured if I could get it work for a few hundred it would be worth it. Time to find a local repairman and have him come get it!

Shipping and packing would be a pia though.
