No picture or sound on Dell w4201c plasma tv

HI
Try restarting,check that every connection that should be connected is connected.
Especially the scart connection, they have a tendency to cut out the sound or colours.
goodluck

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.

bad power supply take it to a repair center cost

This is a problem with the YSUS and buffer boards. These boards are linked on the TV and due to heating issues, they tend to get damaged together and cause your TV to lose picture. These guys sell all 3 boards are are really reliable. I've used them before. http://www.itritek.com/ysusbufferforsale.html

Most cases the Y-SUS, Y upper buffer, and Y lower buffer is the problem. The replace the 3 boards are located on the left side of the chassis when you open up the TV. 90% of the time this will solve the problem.
Look for burn marks on the upper and lower buffer boards (mostly around the chips with the heatsinks on them).

TV has sound but no picture. Earlier it started flasing differnt colors then went black. Whats up can it be fixed or do I need to throw it away?

how old is your plasma tv

Y SUS and Buffers are usual culprit.

He has everything for Dell TVs

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, itritek.com, 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. itritek.com 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.
