If a screen flickers it could be an inverter or a backlight problem. Not sure if it's cost effective to replace, though, in a laptop.

If it were a desktop, the video card could be added or replaced depending on whether the video function was on the motherboard or not.

Walmart is selling new laptops for $288 I saw this season that outperform a lot of computers from just a few years ago.

I haveMy compaq presario CQ40 and my monitor screen got flicker always for past few days and more red horizantal lines @bottom of the screen, where i couldn't see the data,time,date... Plz help me...


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.
