Since it is coming back after a union-like break, it is probably the inverter for the fluorescent backlight rather than the light itself; they can flicker and die but normally don't recover after a rest. The inverter may be a separate board in the unit and you should be able to recognize the right board due to its relationship to the backlight.
This kind of problem will not repair itself but decay further with time.

My lg plasma tv has sudenly when i put it on crackles and sound goes i switch it off and leave it for a few minutes and the sound comes back on


Rice Crispies? We hope not. You may also want to check your connections for security. Switch out your audio cable (s) to rule that out. If that does not correct the issue and your settings are standard, you may need service. ^CL

HI WHEN WE TURN OUR LG 42 INCH LCD TV ON IT WORKS OK FOR ABOUT 30 MINUTES THEN THE PICTURE GOES AS THE SCREEN GOES WHITE THE SOUND WORKS FINE AFTER ABOUT A HOUT THE PICTURE COME BACK AND IN OK ...


I suspect you have a poor contact on the video processor board or the upscaler itself on the screen.
Check all ribbon connectors and look for any components that have got very hot, there may be a dry solder joint beneath them.
Hope this helps.

I have a 42' LG plasma that has now has a 1 1/2 inch verticle stripe on the right side. It used to come and go but now rarely goes away. Any ideas?


I believe that this could be a type of "burn in". If you watch anything with a black stripe on the sides or bottom of the screen often, then this could be the problem. My suggestion is to watch things that have no black side bars for a while (>week) and see if this eliminates the problem.
Good Luck!!

42 inch LG Plasma TV - Lost picture


Most likely what happened is one of the capacitors went bad. When a capacitors goes bad it produces a popping sound. This could be an easy and cheap fix if you find the bad capacitor or capacitors. The bad capacitor will have a bulging top most likely on the power board but could be anywhere.

42 inch LG Plasma TV Lost Picture


Hi it sounds like it has had an elctric fault like a resistor failing.
The click you heard would be a internal switch that cuts off the elctric supply to the screen to stop furthe damage hapening.
It could even be something simple like a bad solder and in that case will need locating and resoldering.
How old is the telly and how often is it used.
When you switch it off leave it off for about an hour then try again if you have allready done this then it probably is a blown resistor are you sure nothing has been pressed on controll have you tried seeing if you can acess the menu screen via the remote and see if that comes up on the screen let me know ok
