Question about Sony PFM-42X1 Plasma TV

1 Answer

Every time i turn on my sony PFM-42x1 the screen flickers and blinks with colored lines all over it. at first it flickers very fast and as the tv "warms up" the flickering slows down until it stops all together and than i get a clear picture. it happens every time i turn the tv on and takes about 25-45 minutes to stop and show a clear picture. any ideas what could be the problem?

    yes i have sound on all inputs (DVI, SVIDEO etc.) when i connect the speakers directly to the tv and when i run the audio out thru an amp.

    about the warranty, well, i got this tv about 8 or 9 years ago, i doubt the warranty is still valid and i can't find the paperwork that came with the tv anyway so we can scratch this option right away.

I have the same TV with the same problem. I am sorry that all the answers are so silly and basic. I just open up mine to check all the compositors to see if their are any Bulging or to see if anything looks damage. I will pull the Power supply and start checking the compositors. and let you know. I will look in other places first to see if I can get some REAL Answers. Poco Zocko Actor

SOURCE: Sony Flat Panel tv with no Picture

Flat panel TV's typically do not have "bulbs," but rather backlighting.  Plasma displays are especially touchy during movement.  I would suggest checking your warranty status, as it's probably not something you can easily repair.  If you wanted to take on the repair yourself, be careful not to lay down the screen, as it will drastically shorten the life of the Plasma display.  I would start with checking the system boards for possible damage, since you did hear a "click," It was probably a fuse, chip, etc.

SOURCE: sony Tv PFM-42 V1 doesn't show any picture or tv menu

This is a common problem with plasma tvs You did not mention whether you could generate any sound like through your dvd player or something like that. Whether you have audio or not makes a difference on which board may be causing you the problem. Just because it does not have a picture for tv viewing does not mean it won't produce some type of sound through your av1 input. Try it and I'll try to be more specific.

SOURCE: my sony xbr5 flickers until warmed up

brennanrp, I hope you purchased a warranty on your TV. My 46 in xbr-5 was doing the same thing. I called the store I bought it from and they took it to a repair shop. The panel inside, basically the inner workings are faulty and Sony has put an extended warranty on it. Get it looked at as it will only get worse. Soon you will probably be seeing some vapor like images across the screen if you have not already. the lines starting showing up even after extended viewing times.

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

Broken screen


You can have them repaired using a TV Repair guy but often it costs as much as a brand new tv. My daughter broke my $1,600 LCD. It would have cost $1,200 to fix.. so I just bought a new one. After that I picked up a TV screen protector called TV Armor http://www.tv-armor.com Its designed to protect the TV from damage. Now I dont have to worry anymore when she is playing near it. It works really well.

It sounds like a bad panel, which is not what you want to hear. Replacing the panel on a Plasma TV usually costs more than just replacing the TV. However a bad panel causes vertical lines exactly as you describe.
