Question about Dell W4201C 42 in. Plasma HDTV

Dell W4201C half black screen

I have been researching this problem online and it seems to be common. Basically, the bottom half of my plasma is black. I still have audio. Is this something a novice can fix? I read some other solutions about power/voltage to the screen... possibly a loose or defective wire. It sounds like Dell repair/support is a nightmare.

It should be easy enough for a Novice to fix.
Most likely the TV has a power supply related problem. The most common thing to go out is the circuit board that supply power to the screen. Commonly called a Backlight Inverter Board.
But, I can't say it's 100% the problem because I can't actually look at the tv over the internet.
If by chance the TV is still under warranty, go that route.
If not under warranty and If you have some electronic experience, if you can find and purchase a Service Manual over the internet and diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you circuit diagrams, test points, and part# lists. Usually, cost under $20.

I hope I shed some light on the subject for you.

Dell w4201c hdtv plasma tv BLACK SCREEN, LOGO FADES OUT, SOUND REMIANS, HELPPPPPPP


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.
