It is a common problem I deal with constantly, the main power board was overloaded there is most likely damage to the capacitors or a transformer on this board. you will need some service tech to take a look for you so he can identify the issue. hope this clear up what you need to do

LG "NO PICTURE" , IF FIX WILL RECUR? ,DID LG FIX DESIGN FLAW 42PC3D


I had same problem - no picture, but sound worked - LG 42PC3d - was two months past warranty, but LG agreed to fix it as a warranty call. Service guy was out within a week to replace the Z SUS(?) board. Works fine now. This must be a typical problem, as LG did fix it, even though the warranty had expired. Good luck.
