Question about Averatec 3200 Notebook
Recently our Averatec running on Vista started losing the screen image through a 'whiting out' of the image and/or a mass of vertical coloured lines obliterating the normal image... this seemed to be time related viz after progressively shorter periods of being on, the problem would arise... and there may also be some connection to the angle of screen tilt, viz certain 'sweet spots' that would return the lost image. The techie at a local PC shop says it isn't a screen problem because there is a good image to start with... he believes the problem is with the VGA card. Problem is that Averatec isn't supported here in Africa. Has anyone else experienced this problem and any suggestions how I could fix it?

Just for the sake of information, the white of the screen means the backlight is working. LCD displays work by allowing light to pass through at different wavelengths, creating 'color.'
I doubt that your system has a separate, replaceable video card. This sounds a lot like a chip has developed and thermal problem. If you can buy 'freeze spray' there, try shooting it into various openings of the case when the problem is present. If this affects the display, you are probably going to need a replacement motherboard since the majority of the chips (ICs) are placed by robots and nearly impossible to replace by hand due to the pin spacing that is typical for modern ICs.
If you are courageous, you can get the case apart with 'jeweler's' screwdrivers. You will find that the screen assembly is connected to the main board via a flat ribbon cable that is likely stuffed into a questionable connector. You might try carefully pulling that cable from the connector and even more carefully, plug it back in again. Unfortunately, few companies are using any gold on connector contacts anymore and the materials used may oxidize and cause the kind of problem you are having.
