LG plasma won't power up

I have an LG 50PG20 plasma and it won't power up. The power source is plugged in and the red light on the power button is on as if it was in standby mode. I turn it on, it clicks like normal, and the light blinks blue 3 times then stays on for about a second like i normal would, then goes red again. Same result no matter how many times I turn it on/off. Pls help as I'm in a rural area and although I have warranty I have no authorized dealer and need to send it far away and would rather fix it myself or at a shop and void my warranty.

There are many different parts that could cause this problem. I would suggest letting the repair center have your unit to troubleshoot the exact cause. The most likely cause is that either your Y sustain board or X sustain board has gone out. It could also be a bad power supply or one of the Y drive boards. Without checking voltages and proper troubleshooting it is difficult to go any further.

Poor color quality


If you are using the component input the red plug could be loose at back of TV or Cable box or bad red plug/wire, try another input to see if color is ok on a video game or dvd player, if it is ok on another input it's probably not the TV but your source or wires

I heard small pop then lost power while watching my lg 50pg20. No red or blue lights on the power switch. What could be wrong?


you are describing a power supply defect. IT may be as simple as the main fuse. I believe the one in this set is a 6.5 amp located on the ps board right by cord connection. IF after replacing the fuse opens a second time you will need to replace the power board.

I have an LG 50PG20. There was just a power surge, and now the TV power will not turn on. The lower left button - which is blue when power is on - is a blinking red. The TV also went 'black' while I was...


You should check the capacitors on the power supply board and others. There were nine bulging/busted caps on my power board that I just replaced for $6.61. Works just like new! Someone who knows how to solder can do it.

My lg-50PG20 powers up and has sound but no display. is it the control board or main board?


Study the screen at several different angles; you should be able to see some ghostly images if the video chain is OK. If you can see this, either the backlight supply or fluorescent light source has failed.
