SOURCE: LCD TV WONT POWER ON

A dead condition usually indicates one of the following: Open fuse (often internal, and usually pops due to other circuit defects). Short (overload condition) in the circuitry. Failure elsewhere in the circuitry. Most modern electronics have some logic circuitry, and if there is a section of the circuit not working, the logic circuit keeps the set from coming on at all.

First, if your power cord plugs into the set, check that it is properly connected. If you can get into the internals, find the fuse, check it, replace with an exact or near exact size.

If problems are beyond the simple, technical expertise will be required to nail down and fix the problem.

SOURCE: My Hitachi model 26L6200 develops

NOT really a solution; I deduced there is an overheating problem likely with a faulty component, so I looked at Thompson Directory and found local repair engineer who has the TV now.
I really wondered if this was a known common problem.
Thanks for you interest.

SOURCE: Samsung 40" LCD turns itself off and on

I had Samsung support come to my house and they said it could be one of two things, one of which was a faulty power supply. Since they only had the power supply in stock at that time, they replaced that, and I have not had the problem since. So hope that helps! And hope it's under warranty!

Akai flat screen lcd tv.. turns itself off after about 10 min


had a very similar situation with my Phillips 42 in. LCD TV.

Here was my Problem. The Power Supply Board. I opened it up( Warranty was Expired) and found several faulty capacitors on the PSB. Its pretty common. Major Electronic companies were sold faulty capacitors that fail in 2-5 years instead of 10-20 due to a lack of preservatives. It wouldn't surprise me if you have the same problem. TV will work fine for a few years and then just fail completely or slowly deteriorate.

Here are the solutions
1. Have it Repaired
2. Check for faulty caps and if you find some(budged or leaking) you know you have located a problem
Remove the board and replace the whole thing.
3. If you have some soldering skills you can replace the faulty caps.
Caps are very inexpensive, under a dollar in most cases. I replaced 4 for about $5.00

Hope this Helps.
Good Luck

Samsung LCD 40 inch LNT4061


Howdy,
It sounds like you have a Power Supply Board problem. The PSB is the center Board (towards left) after you remove the back off the TV. Remove Board from TV with the 6-7 screws. Replace capacitors CM852 & CM853; 2200ufd 25volts.

Thanks for using FIXYA, big IRISH.
