Re: Panasonic TC-P42S30
I messed with adjusting VSUS from about 206 to 220. It did change the picture, but didn't take away the pink ghosting problem.
So here's the entire story on this TV. Hopefully it will be useful to someone else encountering something similar.
My bro-in-law was watching it and it just died. He's had it just a couple years. He tried replacing the power board as he read somewhere that might be the problem. Didn't change anything. He then decided he didn't want to mess with it and offered it to me for a really good...

Re: Panasonic TC-P42S30
Someone suggested I try the screen wipe function (scrolling white bars). After just a few minutes,the pink seems to be less intense and some of the ghost images seem to be disappearing. I'll report back.Leave a comment:

Re: Panasonic TC-P42S30
In the serv mode, I saw a VSUS setting. It had a low and high. I twiddled that and it didn't have any effect on the pink problem. I guess I can try adjusting the trim pot for VSUS and seeing if that does anything.Leave a comment:

Re: Panasonic TC-P42S30
The small white box with black background - looks perfect. Sharp edges around the box, really nice dark black.
Solid bars of different colors - looks perfect except on the white I can see pink fuzzies.
Anything with white has pink in it and some ghost images from who knows where....Leave a comment:

Re: Panasonic TC-P42S30

Re: Panasonic TC-P42S30
Do you have any good references on how these should be adjusted (e.g. what trimpots, etc.)? Thanks!Leave a comment:

Re: Panasonic TC-P42S30
... and could the wrong VSUS cause the ghosting as well?
The good news is it looks like there are some things to try. Looking forward to hearing how the VSUS adjustment goes. I found some other references online to adjusting VSUS, turning the trimpot to change the VSUS voltage up or down until the blacks get solid black. Sound right?...Leave a comment:

Re: Panasonic TC-P42S30
I've attached an image. You can see the Viera menu in the background (the "ghosting" I was referring to).
How do you know where to set VSUS? How is it adjusted?...Leave a comment:

Re: Panasonic TC-P42S30
First off, thanks to everyone here that posted. It really helped me.
I inherited a non-working TC-P42S30 (it was working great and then just shut off). The original owner tried replacing the power board then gave up and gave it to me. I tried replacing the motherboard. After that didn't work, I did what I should have done in the first place and looked for actual troubleshooting info. After reading this forum, I checked SN2 and found it was shorted. Then I checked the 30F131 IGBTs and found 4 of the 6 shorted. I removed these shorted parts and...Leave a comment:
