    It seems like the faulty video card, or video processor section circuit to the mother board to your system. Not a monitor problem.

Sounds like an inverter problem. If the power supply is internal replace the capacitors coming out of the voltage regulators. These are usually 1000mf and/or 470mf. If that doesn't do the trick look up the numbers on the 8-pin chips that drive the secondary transformers on the inverter to see if they are getting the right voltages.
Good Luck!

Chances are the driver tabs inside from the panel to the internal controller board have failed. This is the actual controller board that the internal video card connects to (hidden under the silver cover on the back of the physical panel).
It is not a cheap repair, and it is normally best to source another panel, or just replace the monitor all together.

Is it sort of rolling almost.
If so you have a few bad capacitors in the power supply that need to be replaced.
If you dare to venture inside you should see 1 or more buldging caps. (bowing upwards on the top)
If these start to fail, then they will interupt the correct flow of power and cause this problem with your panel.
Easy to fix if you are electronically minded, if not, take it to your local TV tech and it shouln't cost that much to have repaired.
Remember, inside these monitors is high voltage that can kill, even if it's not plugged in.

SOURCE: vertical lines LCD Dell 2001fp

I had the same problem until I decided to go in to figure out what was happening. I am not a technician but I'm a pretty handy engineer...anyway I opened up the panel and separated the big bulky electronics board which is encased in a metal enclosure from the LCD panel itself. After carefully doing so you will find that the electronics which actually control the LCD is covered by a long and thin aluminum plate. This cover can be easily removed by unscrewing 3 or 4 screws. Now here is where the problem arises. I believe that there is one chip (the biggest one you will see) that gets very hot. I measured temperatures in excess of 110 degrees F. It makes sense that temperature is the problem since the lines begin after the panel has been on for some time. My simple solution to this was placing a fan right over this chip. In doing so you wont be able to place back the thin aluminum cover but that's a small price to pay in getting your screen back to normal. The fan should also be small enough for you to put the LCD Panel back together (without this thin aluminum cover). You can hardwire the fan to the Speaker voltage output. I made this fix to my LCD panel about 2 weeks ago and since I haven't seen the lines again. In my opinion Dell knew that this would be a flaw in the LCD because if you notice the power supply for the panel is external which is uncommon in my opinion. The power supply tends to get really hot so in an effort to prolong the life of the panel they made this an external attachment. Well this obviously didn't solve the problem and they went ahead and put it out into the market. If you would like more details send me an email at Mike28ML(at)optonline.net Good luck, with this issue cus I know it way annoying the hell out of me.

Hi have a samsung 42 inch plasma, all of a sudden it has a band 20cm wide of dotted lines going across the whole screen, some channels or when playstation in use the band gets wider, does not seem to...


if the band is horizontal your tv has bad y-buffer board. Usually there are 2 buffer boards- top and bottom. if the problem is in the top half of the screen replace the top board, otherwise replace bottom board.
but better to replace both a the same time.

if the tv has a vertical lines from top to bottom it may have bad plasma panel and can be considered as not economical to repair.

I have a red line going across the screen. It


Disconnect the inputs to the TV one by one and see if the line disappears. If it does then the component that you disconnected is causing the issue with some A.C. leakage getting into the TV at that point. I have a feeling you have a cable box that is causing the issue.
