Dell Inspiron 9400 LCD Problem

I have a Dell Inspiron 9400 and today I went to tighten some screws hoping it would make the monitor panel less floppy. I clipped the top part back on and turned it on and the colors were all messed up. I figured I somehow screwed up the video card but the colors are completely normal on an external monitor. I popped the part back off and loosened the screws back to their original tightness and that did not work.

The colors can be somewhat corrected using Nvidia's color management utility, however, it seems the pixels are just a bit off. It's blurry. A rea lheadache to look at. Not sure if it would matter but its an Nvidia Geforce 7800, 1440 x 900.

What are my options other than continuing to use an external monitor all of the time? Anyone have any suggestions?

 

Hmm... if the card powering an external monitor is ok, that means the connection with the LCD has probably been tweaked/damaged or otherwise. If it's still under warranty I'll call in and see if they can send someone, a dell tech, with parts to replace it or fix it.

I had a recent issue that caused the system to BSOD whenever I was gaming, watching videos or TV. So I chatted with dell support in India and they sent a tech with a new mobo, which I didn't expect and an upgrade of my GPU from 7800 to 7900. I have the same screen res.

 

I took off the top part and looked at the cable. It connects to the mobo right above the right click key. It appeared that half of it was not connected. I was curious as to if it was sort of how the keyboard connects to the mobo, a little lever that clamps down on the cable, but i did not play with it much.

I saw the cable was sort of "pinched" a tiny bit by where it goes into the monitor, so I played with that a bit. Turned it on and it seems MUCH better. I can't tell if its perfect, or if im seeing things now, but I'm still curious about how the lcd cable plugs into the mobo.

Any thoughts anyone?
