Left 1/3 of screen has "white noise box". I can power up the tv, but that left 1/3 has a box that has no picture. It's just white with a couple of vertical lines, sometimes the line turn red/blue/green. The box just appeared one day. I have been using it for 2 years, had it hung up on wall, and on with a display that changed continuously. Never saw any symptoms or anything that looked like it was going out. I have not tried to troublshoot or called a repair place. I know the warranty is expired. I am a PC Tech so I am sure I could replace a part if needed. I just need to know where to start. Troubleshooting is hard to find on the net. Please help!

Re: Sony PFM-42V1 42 in
Sounds like X buffer/scan or control/logic problems. without good service info you will have a hard time troubleshooting. And it will get expensive guessing. Could even be a panel, probably gonna need a pro look.

I have a Sony PFM-42v1 and it does the same thing, look in your tv menu for picture inversion, usually under screen saver. What it actually does is reduce the chance of screen burnin. By reversing the image it sort of resets the hot areas, brightest colours and the cooler areas being dark colours, switches them around ( negative ). This cools the hot spots and heats up the cold spots.
There should be a option to turn it off, mine and I guess yours as a default is ON, mine has the ON, timer and OFF options.
Hope this helps, please let me know if you need more info.
yes, stop using a plasma TV as a computer monitor. Using the TV this way is an invitation to phosphur burn which these are very prone to. The issue you describe is due to the limitations of the TVs scaler circuit to properly center the image in 720P.
