Question about LG 42LC2D 42 in. LCD HDTV

The TV turns off and then on automatically

We have an LG 42 inch flat panel TV. It is 3 years old. Recently it has turned off and then back on automatically intermittently but at least 3-4 times per hour. We had the cable company in and they put in a new box and the problem persists. Any suggestions??

After switching the tv to standby it automatically turns back on, we have to turn off at the plug what could cause this tv is about three years old


Do you have the tv connected by any scart connections.
If so turn them of 1 by 1 as the scart can control the tv in stand by.
Also when you turn of remove the batteries from the remote if this cures your problem replkace the remote

Have 42 inch LG flat screen...for about 3 years...


Take the back off with no power connected..You should have 2 invertor pcbs..one on the left and one on the right..well the side of the picture you cant see is the same side of the faulty invertor..replace this and this should solve the problem.it is the cheapest option..if not..im afraid is is a new LCD screen unless you are prepared to take it appart and replace backlight bulbs :)

LG PLASMA TV WITH COLOURED LINES OVER SCREEN


If the Video (Picture/Pix) is gone but you can hear the Audio (sound), then it could mean the YSUS PCB Assembly is gone/kaput/finish. Can replace the PCB, not repair the PCB due to timing circuitry involve. Cost maybe roughly $500 depending where you located. The PCB is located on the left hand side of your TV when you are facing the back (Back open). Might find 3-4 brown flex membrane connecting to the plasma panel. The PCB has a silver or black aluminum heatsink (big) on it.
Good Luck.
