LG pdp42V6 sound ok no picture...please.

[moyalt]

I have this Lg rt-42px20 (pdp42V6), which got sound but no picture. got it mulfunctioning from a friend.
Some one already try to fix it, cause the Zsus board FS1 (4A) fuse was blown and replaced with another one (not the original type) the second fuse was also blown. the pdp flat cables (2) connected to the Zsus were pulled out, I guess someone tried checking it..

I checked the power supply voltages, all fine. attached the flat cables back to Zsus, and put in a new fuse. still got no pic, but the fuse hasn't blown.
found a post regrading the 15V comming to Zsus - I got 12.3V, except this the Zsus IPM is cool, Ysus is warming up when plug power.
Another thing, checked voltages on Ysus: Vscw was jumping 111-112-110...should be 120V.

What I need to do next?

I hate leftovers.

It depends on the leftovers. My wife's lasagna is very good as a leftover. A TV that someone messed with is seldom worth touching.

For the OP: These sets have a history of problems due to a failing IPM. The varying voltage also should be investigated.
