Sony PFM-42V1 42 in

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!

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.

Sony pfm-42x1 flickering screen when turning tv on

OKAY I found the Problem!! Bad Caps Compositors. I Proved this in 2 ways. First I took off the Back(always make sure the TV is UNPLUG) In the photo above I put my finger on the capacitors. I found some that where NOT FLAT ON TOP(You can kinda see in the photo too). I could feel a little nipple on top.(Some times you can see if their busted open but not in this case) so I felt them and the bottom right and top left area in red in the photo where not flat. I took my dryer(My wife really) and warmed them up for about 2 minuets each then another minuet rotating back then forth. I leaned the t.v. up to lean on the frame and plug it in. I continued warming the capacitors up and in about 2 Min the T.V. has stop blinking. Much better then the 20-30 min. So the hunt for the Capacitors is on. It will be some work to get the boards out. If everything is done delicately The Soldor job is easy for me. I am going to buy the 8 but replace 1 board at a time until the TV works and put the other on the side for next time or put them up on E-bay. I hope this helped Please like if this helped you. ea0a96a3-fb82-4ec0-89f4-76b4080e9c6e.jpg 1b190ebd-5d69-4553-a009-840d29ab4c87.jpg ab9b51d0-6e1d-4cce-b822-e80d0fde9163.jpg

Sony pfm 42b1 negative picture


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.

Sony PFM-42B1 with black bar in 720p

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.
