HP says this is a hardware problem and just send it to them to fix.
This will cost $398. Is there anything I can do myself or do I have to send it to them?

Before paying HP, you can quickly isolate where those 1-inch vertical color bands are coming from. Building on 's point, the key is to separate panel/cable issues from the graphics hardware.

Try this, in order:

  • If it is a laptop: plug in an external monitor/TV. If the external picture is clean, the laptop’s LCD panel or its ribbon (LVDS/eDP) cable is at fault. If the bands also show on the external display, suspect the GPU/motherboard.
  • If it is a desktop: swap in a different monitor and/or cable; then test your current monitor on another PC. Whichever combination keeps the bands identifies the bad side (GPU vs monitor).
  • Take a screenshot when the bands are visible. If the bands appear in the captured image, it is a graphics output problem. If the screenshot looks normal, the issue is within the display path (panel, cable, T-CON).
  • Check during POST/BIOS. Lines that appear before Windows loads almost always mean hardware, not drivers.
  • Laptop-only: gently flex the lid or press along the panel edges near the affected area. If lines flicker or change, that points to a failing TAB/column driver bond on the LCD (panel replacement is the fix). Also inspect and reseat the display ribbon where it plugs into the panel and motherboard, especially around the hinge where it can get pinched.

What this means:

  • Panel/cable: Often fixable at home by reseating or replacing the ribbon cable; if the panel’s column driver has failed, replace the screen. Parts are usually far less than an OEM depot repair.
  • GPU/motherboard: Reseat the graphics card (desktop), try integrated graphics if available, or replace the card/board. If it is a standalone LCD monitor with fixed vertical bars on any input, it is usually the panel itself; replacement is typically more economical than repair.

Use ESD precautions if you open anything. If none of the tests change the symptom, the $398 quote likely reflects a board or panel swap.

If it is a CRT or LCD monitor , do consider buying a new one. Cheaper...
If it is a lappy.... wait for someone in here who knows.

I should ask... does your sys [if not a lappy] have a seperate video card? Because the problem likely emanates from the video processor. If a lappy, it is likely part of the motherboard. HP. yeah..
