Laptop monitor goes white

Alright, just recently my laptop screen has started to go all white for a few seconds and then back to normal. When it turns white the system continues as normal (music keeps playing, no programs close), it's only the display that cuts out. It can last seconds or a few minutes and then goes back to normal on its own. This can happen many times in a short span of time as well.

My laptop is an Acer Aspire 1694WLMi. The monitor is a 15.4" WXGA CrystalBrite TFT LCD and the video card is an ATI Mobility Radeon X700 with 64MB VRAM.

Any idea why this would be happening? I'm thinking it may be a video card issue that just may need some tweaking, but not sure what to do. Thanks in advance.

if u r willing to do an experiment, do it, heres what u would do, try to connect ur laptop to the tv tru Svideo or anyways you know to connect your laptop to a monitor, this is a test to see which is the problem. if the tv does the same thing with those white screens, that indicates your video card has a difect, and if it comes out normal no white screens then the problem goes to your laptop monitor.

could be the video card or it could be the cable connecting the lcd to the video... even if you can get output to the screen it could still be with the board and not the laptop as the output to the lcd is one connector and the one to the monitor, what ever is different. it could also be the invertor which is a fairly inexpensive fix ( well compared to the screen anyway ).... I would recommend taking it to someplace that works on laptops unless you have had experience taking laptops apart....

If you lightly tap the monitor when it does this, does it flicker?

No, moving the monitor up and down doesn't do anything, just stays the same until it decides to fix itself. Don't really have the cables to connect to a s-video to test it either. If it keeps up I'll probably bring it in someplace. This laptop seems to have a habit of developing weird quirks and then making them go away, so it might fix itself eventually. Any other suggestions would still be appreciated though.

I've always had trouble finding video drivers for this card, would anyone know where I could get the latest? The card is an ATI Mobility Radeon X700. Thanks.

Yes the video card is built in but there should still be drivers for it somewhere right?

If you have access to a external monitor (or a friend), just plug the monitor in to the laptop.
If it continues to work, the problem is in the display / screen, or (I believe) the inverter.

And neither of those possibilities are things I can fix right?

IF you are not confortable taking them apart then no.... If it's the invertor it MIGHT be worth fixing as those tend to not be too expensive and shouldn't take too long to replace.... ( maybe an hour or so ) if it is the screen either you need to deal with it or buy a new computer as screens for dells run $200 + and that is for their small cheep machines....
