20 Most Recent Sony PFM-42X1 Plasma TV Questions & Answers


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

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

this is a sony feature, they have a sensor on the front of the tv to measure ambient and adjust the tv brightness to the ambient light.

if you want to turn this off?

call sony or put some black tape over the sensor.

Check the settings in the menu and make sure you have the input properly set to RGB and not color difference settings (Y, RY, BY).

sounds like there is an issue with the power supply board in the tv. if the fans are not running then you may want to check those connections. also check the power supply board for any scorch marks.

The light turns red to signal the fact that the power source goes in protected mode - its safety system has detected a short on one of its outputs. So yes, it could be a problem with the power source itself - some of its filtering capacitors have aged and are now drawing a lot of current thru themselves. But it's much more likely that the problem is somewhere else - in your case the most probable fault is the Y-sus board, since the fault appears when it's time to start the plasma panel.

Hi, I am sorry but you don not seem to understand these "Standards" these are the result of the Video being Displayed, the TV, only knows it is whatever because the whatever "Tells" the TV, what "Format" to choose, either 1080p 1080i 720p 720i and 480p and 480i you see these are all "Formats, you TV doesn't decide what to display, and you cannot "Force" a non ****p or i, into any other, ****p or i, format. IF the image displayed on the TV is "Encoded" in that format, that is the Format that will be displayed. It is NOT a function of the TV set. Your problem with your colors to me sounds like what happens when you do NOT have the COMPONENT Video, cable wired up correctly, it must be Y, Pb/Cb, Pr/Cr, color to color, but MORE importantly, Y to Y, Pb to Pb, and Pr to Pr... if it is wired wrong you get that condition you have. Check you are wired correctly. The other COMPOSITE, Video out, is the Yellow, Video, plus Red & White, for Audio. NOTE the Red & White, are required when using COMPONENT Video too.
So the best result is obtained using 1080, but as said, it is the MEDIA played that determines that NOT the TV settings.

Please have alook above.

Most likely your Z-sus board is out.
