Fault with the main power supply regulator board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of spare parts + service charge. More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and size.

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...


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

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

Picture has lines and goes black after warm up


Try unplugging for 2 mins. Or press power button for 30 seconds. Your Light in the tv might be shot.... happens every 5 or so years.

you need a green CRT thats whay you have the white kind of concave lines with the green screen. You can try adjusting the green screen control but you need anew CRT ( tube) the speaker cover has two plastic plugs that get removed on the lower edge os the grille which covers the two screws that hold the grille on. If you need more assistancr or where to get a green CRT let me know as I have a link that has some green and red Tubes for your model.
