Does anyone have any idea's what would be causing the distorted picture on my plasma tv? The sound works just fine. I looked for bulged caps no they appear to be fine. The tv turns off and on like it should,

Looks like Zsus to me, Ysus failure normally wouldn't give any image. Zsus would cause distortion. Do you have a DMM and know how to check for S/C ?

I have a digital multi meter but what do you mean by S/C?

Short circuit do you know how to test for it ?

Re: LG 42PC5D Plasma Distorted Pic

I tested all voltages at the connectors and all are good except on the bottom connector on the left side of the power supply, the first wire is marked 3.4v-ON and it is reading 4.7v , All others marked 3.4v are reading 3.38v. Any reason why this one would read high?
As far as checking for shorts I can take readings and post them or if you tell me what something should read and how to test it.

Finally got back to this plasma tv and replaced the zsus board and got some change but still distorted. Any idea's what I should look at next?
