Dell W4201C, White screen on Power up (used to be Black).
TV worked fine for 2.5 years. When I turned it on, I get the blue Dell Logo, and a white background, with 'pools' of black. I describe them as Pools, they are like sploges of black, looks like spilled ink. After a few seconds, the proper black backgound 'kicked in' and everything looked like normal. I watch TV for a few hours.
The next night, I got the same White background with 'spilled ink' effect, however it never corrected intself. The black sploges faded away as the tv images refreshed the screen. But the black never kicks in, and I have a very faded picture. Bright colors are okay, but the black areas are a very light gray.
I don't beleive this is the black problem I've read about from other posts. This is so bad it's not watchable, and like I said, I was happy with the picture for over 2 years.
Any ideas on what has broke? Of course I'm out of warrenty. I spent $3000 on this TV and don't want to chuck it, although I see I can now buy a better TV for $1000.
Any advise on fixing it myself, if it's easyish, or who might repair it in BC, Canada.

Try plasma conditioning for 3 hours: menu, setup, plasma conditioning and let it run for a while. this will hopefully restore the colors, also do a factory reset: menu, setup, fac reset, all settings passcode 3355.

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.
I had the same problem after having a Vizio for 2 and a half years. I
left the room for a minute, i came back and the screen went black.
There was still power to the unit and you could see that the back light
was working, just no picture, no sound, and you couldn't use any of the
buttons. The only way to turn it off was to unplug it. It would then
start up, with the Vizio logo going from orange to white, and then do
the same thing all over, no pic or sound.
HOW I FIXED MINE:Look through the back vents for a white light to make
sure the backlight still works. I ordered a new "main PCB" from
(you can also use searspartsdirect.com). This is the circuit board with
all of the inputs on it (hdmi, cable, etc.) I opened it up,
disconnected the old one, put in a new one and now it works fine. I
both serial numbers on the board to search for it online. It cost me
$144 to do it, but that's better than $450 for a new TV. My tv is the
vx32l hdtv10a. I hope that helps.
For me the part number was either (depending on the vendor) : 0171 2272
2174 or it was 3632 0212 0150. Check your circuit and see if any of
those numbers match up.
For the cheap guy like me who will probably do more harm than good: Also check for the F3 Fuse on that same main input board. It is located in the upper right corner. Hard wired fuses; very small. You will see F1-F4 (F4 is empty). You can solder a replacement fuse right over it. I would recommend piggybacking the fuse with a fuse you can replace. Will need the holder and a new fuse. 6 bucks. Doesn't solve problem, but I can go another 2 1/2 years and the wife won't blame me for screwing up the TV in the first place.
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.
