M675XL Video Card Problem Again? HELP!!

--------------------------------------------------------------------------------

I wrote in last week about the fuzzy blue screen and my video card. Before I packed up my computer and shipped it away, I did a system restore to the week before the problem started and it seemed to fix it...

Fast forward a couple of days-

Every other day or so the computer is reverting to the fuzzy blue screen and lines of nothingness. It is all black other than during the windows splash screen; once in a while there are white fuzzy lines all across the black screen.

To fix it, I have figured out that if I plug an external monitor into the back vga port and toggle between lcd/crt on the laptop, the picture eventually comes back to normal on the laptop. I can then unplug the external monitor and go about my business.

Any ideas what the problem is? It is driving me crazy and I hate to send it in to Gateway and pay so much without knowing definitively what the problem is. Plus, if I send it in and it is in it's "normal" state, who knows what they'll do to it.

Thanks in advance for any and all responses.

It sounds like it could be the LCD monitor. Maybe the cable connecting it to the onboard video is loose or defective or the LCD itself is the culprit. I would say the video adaptor except for the fact it displays fine on an external monitor.

Also do not double post they frown upon that in this and in most forums.

Things that are broke usually stay broke.

Thus, I would suspect you have some other problem, ie, connection loose or frayed.

The next time the screen looks like that, gently move the lid/screen back towards closed a bit and see if that changes anything.

You can try changing screen resolutions and stuff also, but I doubt that is where the problem lies.

I second the recomendation that it is a bad LCD. It is very rare that the cable is bad (in my 8 years of fixing notebooks I have never seen a bad cable). Usually just loose.

From the description of your problem I don't suspect that it could be anything but a bad LCD. If the external display is fine and it eventually comes back to normal on the LCD after playing around with it, there is really nothing else but the LCD that could be the culprit

I have worked on many Dell Latitude C600's that had LCD Connection cables that needed replacing. It appears that from opening and closing the lid the cable came loose and the connector ends wouldn't stay in on the back of the LCD. The only way we could do it was to put a piece of tape over the cable where it connects to the LCD or replace the cable. I guess you can consider it wear and tear.
