Question about Dell W4201C 42 in. Plasma HDTV

Dell W4201 Plasma Television with black screen

Problem started with Rippling lines which kinda looked like cable supplier problems. Slowly got worse and worse and then one day just Dell Logo on startup and fade to Black screen. Now I don't even get the Dell logo unless I do a Hard start. One other interesting note, DVD's and Video game consoles work fine.

I'm in Canada with no warranty left on the televison. No repair centre in my area will even touch a Dell television. I'm wondering, from all that I have read, could it be a faulty power supply and if so where can I get one?

Desperate, and not willing to toss $3000.00 out to the curb.

Do you own the following tools:

plillips screwdriver, pref. cord drill,
digital volt meter

remove back cover of tv. (MAKE SURE TV IS ELEVATED AT LEAST 3FT from ground away from carpet. Please refrain from walking on carpet during diagnostic test. turn dig meter on vdc. THE POWER BD is located on the top middle. It the biggest board on the TV. look very carefully at the board. USE PLENTY OF LIGHT. Back away from the TV for 1 minute. look to the top right, you will see a sticker with leads. Ve, Vscan, etc... located next to each one is the propoer voltage. rturn to the power board. the is a contact next to the specified lead. look for that lead, and take the voltage . repeat process 3 times, from there, get back to me. anything not registering properly, will identify problem with TV.

Vertical black lines. But they are not solid. lg plasma 42pc3dv


This could be a poor connection with the LVDS cable which runs from the main video processing board to the screen, or a fault within the video processor on the main board. Worst case scenario is it could be a fault with the screen itself.

I have 2x2" black vertical lines on my plasma screen. Is this the end of it's life or can they be tuned out? Rod


There are 4 or 5 ribbon cables on the bottom or on one side, they control part of the plasma screen. Check the ribbon cable near the black lines. Unplug the ribbon cable and look for black chips on the underside of it, I think they say 100 on them, you need to resolder both ends on each chip. Should fix the black line issue.

Black lines on plasma


The matrix controler or the matrix drive area is failing. The fix is to change the proper circuit boards, and then do the factory setup to match the board is necessary. In the worse case, it may be the display screen itself that has a failure occuring.

You will have to bring the set for factory service to have the work done. If the set is out of warranty, it may be expensive to service.

Thin Black lines going down my screen, sony Wega Ke-42TS2


These sets are common for bad connections on the ribbon cables connecting the screen to the drive printed circuit board. Or the drive circuit could have a bad drive scan IC. I doubt that but possible. Your going to need to call an AUTHORIZED sony repair servicer to trouble shoot this for you cause any other shop may not have a clue of this problem. Good Luck
