I have an acer aspire 1800. From boot, there are 2 thick horizontal black bands and 2 white bands running from the top to the bottom of the screen. No image is present in these bands. Other bands are there but they show a faded image. The rest of the LCD is fine and backlit. Do I need a new LCD or could there be another solution.

The laptop image is fine on an external monitor so I dont think its the graphics.

Any help would be appreciated.

Following and 's reports of persistent bands on laptop displays, below is a concise, practical troubleshooting checklist and realistic repair guidance tailored to those symptoms.

  • Quick isolation: boot to BIOS or show a full-white and full-black image to see whether the bands are present before the OS/drivers load. If they are present immediately, the problem is almost certainly hardware inside the lid (panel, timing board, or cable).
  • Lid/pressure test: with the machine on, very gently change the screen angle and press the bezel near the hinges while watching the bands. Movement or intermittent changes usually point at a flaky LVDS/eDP ribbon or connector; fixed, identical bands that do not change with angle usually point at the panel/T‑CON.
  • Safe reseat: discharge the laptop (power off, remove battery and AC), remove the bezel carefully, and inspect/reseat the panel ribbon at both the panel and motherboard ends. Look for bent pins, torn shielding, or adhesive that has crept into the connector. Take photos before disassembly.
  • T‑CON and panel checks: a small circuit board on the panel edge (the timing controller) can fail and produce narrow repeating stripes or persistent opaque bands. Replacing the T‑CON is sometimes possible, but often the full LCD assembly is replaced instead.

Practical decision rules and costs: if bands shift with lid movement, try a new ribbon/repair the connector first (cheaper). If bands are fixed and unaffected by all tests, replacing the LCD assembly is the usual cure; screen parts for older laptops typically range from about $30 to over $100, plus labor. For repair how‑tos and part identification (panel part number on the back label), see the screen replacement guides linked below.

Did you ever find a solution to your problem or did anyone ever suggest one later?

My IBM R52 ThinkPad has just developed a similar color-band problem but with just two vertical bands. The display was perfect the last time I used the computer but without so much as moving the thing, when I opened it to use it today, exactly 5cm in from the left edge was a 5cm black, top-to-bottom band followed by an adjacent white one, also 5cm. To the left and right of this pair of bands the display is perfect.

Each time I have rebooted to see if anything might change, the display starts out the same way but sometimes with the black and white positions reversed. Then one or the other or both bands turn into an array of very narrow stripes of different colors. The right band sometimes has started flickering for a while, with the white almost disappearing and allowing the normal screen behind to show through, but then the solid, opaque white comes back. One time one of the bands was a consistent bluish color instead of black or white.

From the other posts on display aberrations, my best guess is that the problem is a defective display cable, bad video card [ATI Radeon X300], or a loosened connection. The ThinkPad support site has nothing on the problem that I could find. Any suggestions?
