With this TV it has alot of problems with the ZSUS board and the Z board is controller logic board mounted behind A/V input board, first look at boards for swollen or puffed up capactors if there is any like that replace them,Alot of them have poor solder connections this can cause all kinds of problems ,but ZSUS board is probly your problem Call UED for any parts 1-800-648-6657 and try Encompass 1-800-638-3328

Hello Tiangston9.
These plasma TVs have a common failure with the Ysus boards, more specific an IC that is underneath the big heatsink. The capacitors in the power supply became defective as well.

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.
