Sony pfm-42x1 flickering screen when turning tv on

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?

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. sony pfm-42x1 flickering screen when turning tv on - ea0a96a3-fb82-4ec0-89f4-76b4080e9c6e.jpg 1b190ebd-5d69-4553-a009-840d29ab4c87.jpg

    i did the test with air dryer but i warmed up only 2 capacitors at a time. turns out only 2 capacitors are actually bad (the two at the top left corner) when i warmed up this 2 the tv showed clear picture in about 1 minute. warming up any of the other did not do anything. replacing them is not going to be easy. i will take it in to have it fixed the right way. there is no point turning a small fix into a major problem. anywho, thank you poco zocko for the good advise.

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: vertical flickering color lines instead of pictures

Soory man there is no deflection yoke or vertical output IC in a plasma TV set.LOL This person has a problem with whats called the substain power supply or bad caoacitors in the main supply. there is also a possibility that the set has a bad tuner. Only performing test on the set will determine the problem.

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: sony pfm 42b1 negative picture

Hi,

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.

I have the same TV with the same problem. I am sorry that all the answers are so silly and basic.

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.

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.
