Mid 2009 13" MBP iSight camera bad picture quality in photo booth

Question

My daughter's stock mid 2009 13" MBP 2.26 ghz intel core two duo has a problem with the isight camera. The isight camera is built in to the screen. The isight camera works some of the time flawlessly and other times it comes out real grainy and with small colored pixels all over the screen like colored static (about 20% to 30% of the photo booth screen is affected but the rest of the screen outside of the photo booth app is unaffected). She only uses it in photo booth but we've tried the iChat app and the same thing happens there too, once she couldn't get the MBP to connect to the isight camera (it just showed a black photo booth screen), so she closed the lid of her MBP and reopened it and it worked. All of the software and firmware is up to date and we've tried resetting the PRAM and the SMC, it didn't do anything to fix the problem. It seems like there's a wire loose in the computer from the screen to the computer base, only because I can move the screen back and forth and the picture quality changes, the amount of static on the picture will move, go away or get worse. I had the screen changed in early 2010 (January or February) (the MBP was about 5 or 6 months old then) at the apple store under warranty due to dirt under the screen's glass (manufacturing defect). The photo booth picture static problem comes and goes, but here lately it comes more than it goes. The screen in general is in good shape and doesn't have any detectable problems with it, it has a good picture and no dead pixels, the problem seems to be only isolated to the isight camera. Can some one help with this problem? How long of a warranty is given on the warranty repairs (like the screen change they did in early 2010)? If apple does a repair on it and finds a wire that has rubbed the insulation off of it on a hinge causing a short and the isight problem, as a result of a sloppy repair from the first warranty repair, will they cover it under warranty again even if it's been over a year since they changed the screen? Also how honest will apple be if they do find out it is a problem caused from the first screen replacement, will they own up to their mistake? If I don't agree with apple's repair decision, can I get a second opinion from an outside source, third party, and if it's diagnosis different than apple's and can be proven, can I still get apple to do and pay for the repairs and labor if it turns out to be their fault from the first warranty screen replacement?
The reason why I'm asking is, I took my wife's white macbook in about a year ago for the famous cracked top cover replacement (under warranty) and when I got the computer back, the isight camera didn't work, so I gave it back, they took it apart a look at it and said there was nothing wrong with it and gave it back, then the screen wouldn't come on so after 4 hours at the Apple store they decided to send it to Austin, TX. for repairs (I'm in Ft. Worth TX.). Apple in Austin said it needed a new main board. They said the old one had water damage to it. We never had water anywhere near the computer, not even in the same room. It was working fine when we took it in, we took it in just to get the plastic top case, that cracks all of the time, replaced under warranty. And then they wanted us to pay for an $800 main board because some how while they were doing the top cover replacement it got water damaged. I argued with them and they finally gave me a one-time offer of them paying for half of the repair and labor or if I disagreed or left the store I would have to pay the whole amount if I chose to have the repairs done. So I ended up having to pay $467 for a year old macbook main board that was water damaged in their possession during their repairs. I like Apple and their products but I am worried about giving my daughter's MBP over to them for repairs because of this incident, it's an honesty issue with how honest they will be with what they find because they won't give back the old parts for analysis by a third party to verify their diagnosis.
Thanks for any info and advice anyone can give.

Hi,
As a personal note I find long posts like this hard to read if they are not broken up in to paragraphs.
As I say it is  a personal thing.
I can give you some information about the camera and laptops over the past few years.
Basically in early Laptops of the MacBook Pro and MacBook range the cable did tend to fray at the point where it passed through the hinge.  It did take a well used laptop that had the lid open and closed frequently to cause this.  (your 2009 model might just be in that group - I have no firm dates or models I am afraid)
Later models have this rerouted so that this does not happen.
However the cable has then tended to get pulled from the camera end and become loose.
This On Line Self fix site has pages about some models  (The one I have linked to may not be yours)
I have linked in to later pictures in the sequence but there are navigation points to work back to the start.
Note:- they use pretty specifc specialest tools as well in these pics.
Doing this would certail Void any Warranty you have left.
From Posts mainly in the iChat and the iSight areas I have gathered that it seems common for Apple to replace the Screen as a whole rather than fiddle with getting solely at the camera.
Apple has this article on Trouble Shooting an iSight
Basically it says try several apps then try logging in on another Mac User account to see if it is App based or User based or in fact System wide.
If System wide then resetting the SMC/PMU is the only suggested fix.  (Which I did read you had done)
In addition to that I would add that testing should be done in different lighting conditions.
Lighting in the evening or dark that is good enough to read buy is not always good enough for the camera or is not illuminating the right areas.
Some people have reported that Starting the computer in Safe Mode (then Rebooting afterwards) seems to help.  (it clears out some caches and starts up with reduced extensions)
As to actual Repairs and any Warranty that may still be in place I cannot say.
I can say that when people post about problems with repairs a certain stores someone else will tend to post that their experience was different.
You seem to report two different experiences with the two computers yourself.
