Hello, I am having a problem with the display flickering on start up. Kind of like a vertical hold problem on the old sets. The colors seem to change until the set is warmed up. It seems to be taking longer and longer for this problem to clear.About 15 minutes. It is more than likely a board problem?? I was told that any one of the boards cost was about 500.00 or more. Because it is an older set i didn't want to put to much into it. I was hoping that maybe it was something that happens on all pfm42b2 sets and had an easy fix. Any help would be great. Thanks much Larry D
Call Sony at 1-877-650-3477 and tell them what happened. they SHOULD send a shipper to your doorstep free of charge to come pick it up and take it sony, where they should fix it free of charge, because this is a MFR defect that has happened to hundreds of this model. Trust me, I know I just did it yesterday :)

If any buffer board is faulty, this kind of fault can occur. Might have a panel fault too. It will be best to contact any service technician, to make it confirm. If you wish to get more details, check this link. http://electronicshelponline.blogspot.com/ Selecting the view option, either to Mosaic
/ Time slide, can be selected by the drop-down list, at the top left

Hello Depending how wide the line is their could be two possible causes.
I have two questions for you.
1. How wide is the line.
2. Does it run from top of screen to bottom of screen?
If the line is thin a single strait line then it is possible the PDP has gone Bad (Panel). (Screen). The screen will to be replaced.
If the line is at least 2 or more inches wide then its a buffer board which can be replaced. LG calls this board Hand insert Boards or display driver boards..
It sounds like the video output isn't working its most likely a component failure 1 thing you could try is connecting a rca cables from video/audio out on the set to another set vid/audio inputs to see if it the video gets through.This is a problem that requires technical knowledge and test equipment to trace the video signeal
