Question about LG 32LC7DC 32 in. LCD HDTV
As above . was working fine we turned off and now it won't come back on . powered off for 5 mins and still the same
Sounds like it started "Protection Mode" because of a failed electronic part inside the TV. When this happens, the TV will keep turning itself OFF or will not turn ON at all. This keeps the other part inside from being damaged. Most likely the TV has a power supply related problem. It's possible that it maybe a badcapacitor or transformer on the power supply board.
The common part to go bad for flat panel screens circuit board that powers the screen. Most manufactures call it a Backlight Inverter Board.
But, I can't say what is 100% the problem because I can't actually look at the tv over the internet. I can only make guesses with the symptom.
You have a few choices:
1. You can again try leaving the TV unplugged for 30 - 45 minutes so the TV can discharge and reset itself.
2. If by chance the TV is still under warranty, go that route.
3. If you have some electronic experience, if you can find and purchase a Service Manual over the internet; It will help you diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you circuit diagrams, schematics, test points, and part# lists.Usually, cost under $20. And most cases the new part cost less than $15 by searching on the internet with the part number.
4. Pay a TV shop to do the repairs. It maybe costly, but get an estimate of how much they will charge. That way you can decide if it worth repairing or replacing the whole TV.
I hope I shed some light on the subject for you.

Here's a link to the service manual for a slightly larger LG LCD TV. Perhaps it may be of some help? The troubleshooting section appears to be the same for many models of LG TVs...

Power failures can cause all types of problems, have you firstly checked the fuse in the mains plug? If that is ok then it may have blown an internal fuse in the power supply board, these are there to protect the rest of the circuit from power surges.
