Question about Sony PFM-42V1/S (Silver) 42 in. EDTV-Ready Plasma Television

1 Answer

My Sony PFM 42X1 has a perfect picture but only Top half works.

My Sony PFM 42X1 has a perfect picture but only the TOP HALF. The bottom half has a lot of 'noise' as if a screened cable is faulty. No picture. But the colours (Vertical) move in sympathy with top vision. The type of problem you get with sound. If this all makes sense!! The agents are not able to repair. I have a good idea what PC board they tried it with. The one BELOW what seems the main input PC board. Can any one help? It was made in August 2004

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-42V1 bottom half of the screen is a blurry ghost image of top


The Sony Plasma designe not to repair at component level your problem I believe in YSUS PCB you can adjust a few variables resistors on this PCB make sure to mark on the spot before turn you can alway go back to original point, set your plasma on normal channel turn the variable resistor slowly and observe the picture any spot will effect the picture if you can not adjust you need to replace a new PCB
Let me know how you go

If the loss of picture is either on top half or bottom half of screen. there are y buffer boards that go from top to bottom on left side of screen when looking at back that control those sections. when there is loss of half of picture then buffer associated with that area would be at fault and would need to be replaced. when i see a degrading symptom such as loss of picture on top half or bottom half leading to no picture issue normally you would check heat syncs on y sustain board and if not heating up after a few minutes of being turned on would recommend replacing y main and both y upper and lower y buffer boards as they complete a circuit
