Color lines running down the screen


That can be caused by either the Tcon or the panel itself may have an issue. The TCon is most likely though. Your audio works correct right? I would try a new TCon you can get them from www.tvrepairworld.com

i would hook it up via an optical cable for audio or left and right rca cable for audio and try and stick with components for the video should solve the problem. the no color means if you are using a component cable you have put them in wrong. the blue and green look alot alike ihave messed up before. also i did some research on this model. i have heard some people running into these problems no matter how they hooked it up. hdmi the way to go tho.

Hp 2500l prints a dark line horizontal down each page. Can we clean drum at home?


A dark line on the hp 2500 series can come from the drum You can't clean it at home), it can come from a toner cartridge, from the fuser unit and from the optics.
Step one - check if the line in all colors, run copy quality check through Menu and diagnostics, if the line is only on one color your problem is the toner cartridge.
Step two - if the line is on all colors, take the drum unit out and look at the drum, if you see the line on the drum you need to replace the drum unit.
Step three - stop a print in during the printing process by turning the printer off, take out the drum and look at the printed paper under the drum, if the printed page is clear of line your problem is in the fuser.
Good luck.

Faint horizontal dark line about 2 1/8 inches down from the top


Hi,

You can easily fix this yourself, one of the quickest ways to fix it is to print 10 doublesided blank pages and it will clean the inside of the machine for you and the line will vanish.

For further print quality problems on this machine follow these instructions to troubleshoot.

When troubleshooting image quality problems, it is important to understand the situations in which the problem occurs.

Print a copy of the color test pages to determine whether the problem is in one color or more than one color.
  1. Press the [Up] or [Down] arrow button on the Control Panel to select [Troubleshooting] on the Display Screen, and then press the [OK] button.
  2. Press the [Up] or [Down] arrow button to select [Print Quality Problems], and then press the [OK] button.
  3. Press the [Up] or [Down] arrow button to select [Color Test Pages], and then press the [OK] button to print the test pages. If the problem occurs with one color on the test pages, perform the solutions for this problem. If the problem occurs in more than one color on the test pages, restart your search and select a case for the image quality problem occurring through all colors.

Black Lines running down the right side outside of the print area


It may be the fuser. Take it out and inspect the roller on it:

  1. Switch off the device, disconnect the mains plug and wait for 30 minutes before continuing.
  2. Ensure that the bypass tray is closed, or you will not be able to open the front cover.
  3. Open the front cover by pressing the release buttons as shown.
  4. Pull the front cover down towards you.
  5. Disconnect the green plug - squeeze the sides of the plug and pull.
  6. Push the left and right levers outward to unlock the unit.
  7. Pull the unit towards you as shown and lift it clear of the device.
  8. Check the roller for wear marks, If so replace it.
If I could be of further assistance, let me know. If this helps or solves the issue, please rate it.
Thanks, Joe
