Do you have heater voltage because if you are hearing high voltage you may need to replace a resistor and capacitor in the 200v circuit or you could possibly have a anode not seated right arcing on somthing or a bad flyback

My LG 42Lc7D tv just made a pop noise and then went back. The tv didn't turn off, it is like a more lit black screen. I unplug it and plug it back in, it works again for a few seconds and then it all...


This means that the lamp for the tv has gone out. This is replaceable but it is in the $200-300 range plus labor. If it is under 2 years old it should still be covered under warranty for this problem.

3 year old 42in LG LCD TV scrren went blank


You will either have a fault with the inverter board which drives the backlights or a faulty backlight in the screen. If the problem is a backlight then a replacement screen is the only cure. One or the other is breaking down after it has been opn for a certain period of time, have an engineer call out & check with a tester if it is a screen problem.

The picture on my tv went small


Go into your picture set up menu, which should be in the main menu for the TV, and change your aspect ratio.

42 inch lg tv powers on,goes off after about 30 seconds


I have the same problem, I just spoke with LG Customer service. They had me unplug the power cord, hold down the power button for thirty seconds, plug back in and turn it on, this DID NOT work for me, but maybe it will work for you.

Good Luck! Mine is going to a service shop, maybe what they tell me I can post and it will help you if you have not gotten your tv fixed yet!

LG hdtv lcd wont turn on will only go to blue screen


How old is the set.. If you its relatively close to being out of warranty LG will probably cover the repair. Contact them at 800-243-0000.

42" Lcd problem


I belive the repair shop might be try to get more money from you
if you enscrew the back of the tv ( with the tv unplugged ) look for a flat wirestrip thats not connected
I think they either forgot to plug in that video wire or they did it to make money from you

did it work fine before the dim screen or did it come back to you like that?
