Your plasma tv goes to standbye because protection circuit is activated . Usually there is some thing wrong with one of the boards inside your tv . First try to make a reset to your tv by disconnecting the main plug from wall socket , wait for 15 _30 minutes, then plug it ON , try to use remote controller to switch it ON .
If the problem still exists ., then you may need to take it service centre or ask a specialized technicien to fix .

The click sound is the power relay coming on and off. The tv is sensing a power problem and shutting itself off. If you are handy, remove the back of set , disconnect the connectors to each board and check voltages out of the power supply. If they are not to speck, replace power supply board. If they are ok, reconnect one board at a time and see if power stays on. You should be able to find the bad board this way. Visually inspect each board for burned components or swollen capacitors.

SOURCE: 42 inch LG Plasma TV - Lost picture

Our LG 50" plasma tv screen went black after a popping noise but still had sound, after great diliberations decided to take the back off and have a peek!
We unplugged the tv and tested the fuses (there were three we could see) one had blown, the one on the left as you look at the back of the tv it also has one above it. We wrote the code/seriel number down and took the fuse to the electrical wholesalers Maplin and bought a pack of 10 fuses for £1.29 replaced the fuse in the tv and everything now fine!!!!!!
Hope this might be of use to anyone whose lost the picture after a loud popping/snacking noise but still has sound.

My 42" plasma is making a clicking sound, then it switches off and keeps clicking but not switching back on, when it does go back on it stays on for just a few moments, it is only 14months old.

I think you have a defective power board. the pop sound in coming from the board and giving you a low output voltage. do it yourself price about two hundred for parts.

These blinks [flashes] are fault indication (Error Codes).From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit stage inside it.This will make repair easy.These are called blinking codes. Make sure about the exact number of blinking of the standby/power led, by switching On & OFF the set, for at least two times.Count it carefully.If you wish to get some details, check the site linked here.It has details about blinking codes, and fault locating, to many popular brand TVs and other devices.Viewing it in "Mosaic" will make surf easy.

LG plasma turns off and on by itself while making clicking sounds


Probably the power supply is failing. The clicking sound means the power supply is trying to turn on but can't.
