Oh yes, I have checked everywhere for solution. Now very curious.
I got it to where it would boot and display without all the display corruption ( many thousand stripes like a tv on horrible horiz.hold problem.
Booted it 20 - 30 different times to test over & over. Worked until I packed it into the tote case, laid it aside a few days. Tried to boot again, back to square one. All the pretty colors and no actual way to view.
Heading back to use ext. monitor and run scan disk again, but going to try chkdsk /r also first ?

Dell Inspiron 4000 laptop, Windows ME OS., 512RAM, Had previously pulled and tested cable and inverter. But still had issue even after that. reseated mem. sticks.
etc. etc.
Now simply totally confused. It worked and worked, but unplugging, laying aside (untouched/ bumped / etc.) now it's acting up again.
UGH.
Any Ideas ??
Thanks in advance. Nan

Intermittent, high-density color banding that appears after handling or packing usually indicates a hardware fault between the system board and the LCD panel — most commonly a damaged/fatigued LVDS/video flex cable, the panel’s internal driver board, or cracked solder joints — rather than a Windows driver problem. The forum discussion points in that direction; a few focused, non-destructive checks will quickly narrow the cause.

  1. Boot to the BIOS/POST screen and observe the display. Artifact presence before Windows loads points to hardware.
  2. With the screen active, change the lid angle slowly and watch for changes. Intermittent artifacts that appear, disappear, or alter with lid movement strongly implicate the hinge-area flex cable or its connector.
  3. Gently press around the back of the panel and along the hinge while watching for the pattern to change; reproducible change under pressure is diagnostic of an intermittent connection.
  4. Photograph the screen when the stripes are visible — a still image documents the pattern and helps when comparing before/after tests.
  5. Inspect the LVDS ribbon at the hinge and both connectors (panel and motherboard) for frays, bent pins, or corrosion; reseating the connector often yields a temporary cure that confirms the cable/connector.
  6. If the pattern does not change with movement, the internal panel electronics or motherboard solder joints may be failing and will need deeper board-level diagnosis or panel replacement.

When attempting any disassembly, disconnect AC and battery first and observe ESD precautions. The inverter/backlight area on older models can carry high voltages and should be treated cautiously. Replacing the LVDS cable is the lowest-risk, lowest-cost repair to try first; panel or board repairs are more involved. This follows ’s connector nudge and ’s hardware diagnosis, and is consistent with the general Dell panel-failure patterns noted by .

Did you disconnect and reconnect your display cable as well? I had a similar problem with my Dell a while back and this fixed my issue, best of luck.

I had the whole thing apart (carefully of course) worked ok for 30 boot up tests then died again. ?
Tried reinstalling drivers etc. No joy.
I can get video on external monitor tho.

I think your monitor is gone...
Or maybe your video card is bad now.

I think that this is a hardware problem.

Dell laptops suffer from these type of display failure within a year of the purchase .
my boss had the similar issue and he he spent around $50 to get it back .
the only solution for this is to use the computer in cool environment
