Question about Dell W4201C 42 in. Plasma HDTV

W4201C no picture only sound

I recently discovered my 2 yr old TV a Dell W4201C turns on. I get the DELL logo for a split second but looks to be very pixelilized . The logo then fades after 2 seconds and a black screen is all there is but with sound from the cable box. I tried shining a flashlight into the TV and do not see an image. Any other suggestions???

Try to use dvd player to play video to determine where the problems goes wrong either from the video signal of the cable provider or from the TV itself.

Please let me know any update.

I have a dell w4201c hd tv first got it used only the DELL logo comes on very clear purchased a main board and the tv came on worked perfect after 2 to 3 weeks turned on and picture comes in dim every...

Change input device to some other like a DVD player and see. Check for loose contacts in power outlet, RC cable, jack and socket. Try resorting to factory default settings. If nothing works, you may have to look for any dry solders, leaky/dry capacitors on board.

Picture is fine for about an hour then goes fuzzy

Hello Townsend, It sounds like a problem called blooming, or you are having a problem with focus control which are signs of a problem in the horizontal and high voltage section of the tv in the case of plasma TV this would be the excitation circuit. I would suggest that you take the set to a TV repair shop to effect repairs.

the problem can be traced from the power bd. you will need a digital volt meter. There are settings located on a sticker located on the upper right corner Va,Vset,Ve, Vset etc..... each one has a DC voltage. compare the voltages to trace the source. My suggestion from experience is the Y Main upper or lower buffer which ever has a brn mark located on the metal of the panel. Google a local dell dealorship or a repair company in ur local area, and get serviced.

the problem was the y-sus board, i had a local tv repair shop diagnos that much for me. although, he couldn't fix it i did some research and found a company in california,, who could. you send him the y-sus board and the two buffer boards and he not only repairs them but he upgrades them. apparently the y-sus board gets too much heat and eventually goes out, sometimes the buffer boards are affected too. replaces the components on the y-sus board with better parts which are more heat resistent. i believe this will help you with your problem. let me know...good luck.
