Question about Dell UltraSharp 2001FP 20.1" LCD Monitor
I have 2 inch wide vertical band of red and mulicolored lines on my LCD Dell 2001fp from top to bottom what can be done?
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.

This fault is a tab fault on the lcd board under the shield attached to the back of the lcd. I worked with a company that repaired lcds in a clean room and it takes a lot of special equipment. the special "tape" that is placed between the tab and glass and pcb has to be kept in a refrigerator until used. The solution though temporary is to keep the heat from rising to the tabs, top of the lcd, as much as possible. the solution with the fan is good. it seems just removing the shield is 85% effective. this was poor manufacturing by the lcd makers. the second tab from the left when facing the monitor is the main culprit though a few others have failed. you can move your finger over it while powered and make the fault occur

I had the same problem, the left-side banding. It started about 3 days after I got the monitor at an auction.
Read Francisco's solution (above) after I had taken it apart 3-4 times, sprayed it, jiggled it, gave it a slap, etc. I couldn't get the fan to work, not on the audio plug, not even after trying it with about a dozen old black 12vDC adapters.Finally ran some wires in parallel to another fan inside the computer. The fan was only .08 amps, that was the problem, I guess.
Finally got the fan mounted (you need a hacksaw, drill, and screws) and turned it on. I still get a tiny bit of a ghost of a band when the screen is, say, all blue background, but who cares? Probably because of my tiny fan. The monitor is 98-99% okay, and very usable. I have been using it since the patch-up for about 5 weeks with no problems.
Now I am trying to figure out how to re-attach the monitor stand, or to attach another stand to it. I have it resting against some glass bricks now.
Muchos Gracias, Francisco (Mike)

Replace the lcd matrix or replace the monitor.

The LCD panel itself is bad, most likely the welds between the glass and the tab board. Probably not cost effective to repair.
