Presario C717NR screen problems

So this has been a nagging issue for me that started about a year ago, and I'm finally trying to get it resolved.

I had an issue where if I opened the screen anymore than 4-5 inches, it would freeze half the screen and turn the over half into a complete jumbled mess. I ordered replacement screen about 2 months ago, and w/ me being lazy and all, it's been sitting on my office floor. I've been using the laptop daily, but instead it stays on my desk and is running through an Acer desktop monitor w/o any issues whatsoever.

So I brokedown and started installing the new screeen today, only to get this when I switched the output back over to the laptop:

It made an audible whining noise both times I switched over, so I quickly switched it off. At this point I'm wondering if the cable from the motherboard to the screen is the issue, but I don't wanna keep throwing parts at a computer this only cost me $250 brand new.

Also, when I finally get this figured out...I can't remember which plug this mic connector goes into.

It can either go here next to the keyboard cable or over here by the fan. Does anyone know?



Thanks all.

hmm well its probably one of 2 things. Make sure you properly seated your lvds connector on the motherboard and to the lcd controller on the back of the lcd. Also the lcd you ordered is it the same part number as the one it is replacing???? If it is then its most likely a bad connector cable or it is not seating correctly. If it is a different part number then post both the original and the replacement and i will take a look and let you know if I can help more.
