Why do I have sound but no image on my LG 42pc3d-ud Plasma TV?


This is the sad story of many a so called smart TVs. I have repaired several of Samsung smart TVs. It is the back light in the panel which fails and company guys advise you for a panel replacement. Once you can see LG symbol means the Tcon is working. It is not the picture which is disappearing, it is the failed backlight which is not there and so you can not see anything. Repairing panel is a tricky job and you need a certain amount of expertise for this. Otherwise you may damage it beyond repairs.

I have a LG 42pc3d-ud i can get green (power light) but know picture on tv (like power is off and have humming sound comming from back


From your description it sounds like your TV it's actually on you just can't see a picture. That is usually caused by your Zustain boards. The zustain boards are located on the left and teh right side of the TV. You can check the fuses to see if one of them is blown or you can leave it on and see if one of them does not heat up. You would have to replace the board. You can find part at www.interliquidparts.com
