Just finished a routine screen replacement on a Compaq Presario NC6400. This machine had been displaying intermittent video corruption problems for some time and, having eliminated the other possible causes, a screen swop seemed the only solution.
The Compaq was up and running in no time with a new lease of life and a smart new display. If your laptop screen is broken or has simply failed, then book it into the Surgery for a speedy and cost effective procedure and restore it back to health.
