Monitor Problem - help requested

Dell computer corp / INSPIRON 6400

Specs: Windows XP
My laptop display (Dell Inspiron 6400, purchased Dec. 2006) has about a two-inch vertical stripe running down the middle of it. It is usually a shade of blue, but changes colors at times and sometimes has stripes. It is also usually about 50% transparent, but can be completely opaque.

I posted a few pics to show what I mean. Note that these are modified screenshots to show what I see. The actual screenshot images do not show the display problem. Example 1; Example 2; Example 3.

I found through accident that if I apply pressure at the top of the screen, it will usually fix the problem temporarily or at least make it better.

Taking apart the display case I disconnected, inspected, and reconnected the wiring. I'm pretty sure it's not the connection there, but somewhere in the circuit board at the top of and behind the screen, or its connection with the screen itself.

Wondering if someone else has had this problem, if anyone knows the actual cause, and if it can be easily fixed by me (say by opening up the 'do not touch tape' and soldering something).

This will probably need a replacement LCD. They are not unreasonable. You can expect from $50 to $200 for a replacement and they are not that hard to replace. I don not know how to disassemble the actual LCD and troubleshoot/repair a broken one. This is why I say it just needs to be replaced. What I would do is disassemble it and give it a once over visually to see if there is any noticeable damage and if you think you can repair it then do it. The LCD's are basically held together with tape. Bottom line you will be replacing the screen to get rid of this. Ebay it for teh best price. Best of Luck.

I was able to get a new display off eBay for $70 per your suggestion. Works great so far and easy to install.

Now I get to play around with the old one and see what I can learn.

Thanks for the help.
