Qosmio G30 video problems

So I've had my Toshiba for just over 3 years now (figures now the warranty is up) but i think theres something wrong with the video card. The screen tends to flicker. Kind of like squinting your eyes. I never loose the feed, but it dims for a second and comes back rapidly over and over, then its fine. sometimes when i tap on the unit, sometimes when its on a table thats not moving. I got it into a repair shop before the warranty was up and he did a "video reset" as he called it. Basically he said he unplugged the video card and plugged it back in. Because according to him it sounded like a loose connection. What do you suggest I do?

 

Check the LCD cable.

Have you used an external monitor? Does it work properly on that?

 

yes, when i use the HDMI its stunning. where is this cable. i cant find any pictures of the inside of this computer on the net, so i can possible find the cable without ripping apart the whole computer. thanks

 

Well, as far as I know you have to get the the motherboard and the screen, or something like that. I've never seen the inside of that model, so I can't really help you.
