Hook an external monitor to your laptop. If from the external monitor, it will display fine, then videocard is good, replace the LCD screen. If it has the same problem then you need to replace the videocard. In this case, possibly the whole motherboard should be replaced.

This is usually a sign of either a bad LCD screen cable, a bad LCD screen, or a bad display adapter.
If you connect an external monitor & you get a picture without these red horizontal lines, then your display adapter is OK.
Diagnosing a bad LCD screen cable or a bad LCD screen requires that you disassemble the LCD screen panel, & swap them one at a time with a matching part. This way you can identify which part is causing the problem & replace it.

Hello:
Your most likely cause to the color flash on your screen is a bad LCD panel. One way to troubleshoot this is to hook an externa monitor up to your laptop, and observe the display on the external monitor. If it is ok, then your LCD is the cause. If you still experience the flash, you could have a motherboard video problem, but unlikely.
There is no easy fix to get rid of the flashing line. If your laptop is still under warranty, or even close, I would contact HP /Compaq customer support and explain your laptop's problem.
Hope this helps !

The monitor reads: system boot failure. Insert recovery disk.


McAffee Security or adding memory cards should not effect the ability to do a system recovery, but so be it. Here is a list of presario laptops, do you know which is yours?
