Red "Snow" on LCD laptop screen

By jrsocrates ·
I have a Compaq Presario 2100. A couple weeks ago, I noticed a weird phenomenon. I get red "snow" (like on a fuzzy TV channel) on my screen in places where there should be black. For example, when the computer first turns on, there used to be a black screen with the Compaq logo. Now there's a *red* screen. And on my windows desktop, the parts of my background that ought to be black are red. It's not a huge deal, since this is an aging machine and I mostly use it for word processing, but I was wondering what is causing this and if there was anything I could do to fix it?

As this is a NB it's most likely to be the M'Board

by HAL 9000 Moderator In reply to Red "Snow" on LCD laptop ...

These lead a hard life and if they are regularly moved around you can slightly bend the entire chassis which causes the M'Board to become slightly bent. As this continues to occur with different trips you eventually get breakages in the solder joints on the components to the M'Board and the unit will stop working.

If you where just getting a different colour being displayed on a random scale the most likely culprit would have been the Monitor connection to the M'Board but snow is the M'Board telling you that it's beginning to go away.

Adjust Brightness

by carano In reply to Replace the M'Board as th ...

The video on the motherboard may be going but before you replace it, adjust the brightness until the red turns black. On my older machine I adjusted the brightness from 0 to +8 and the color has been fine now for quite a while.
