I am now working on a ASUS G73jh. I'll describe the problem from when I first acquired the laptop. The laptop started up with a blue BIOS background, eventually the OS started. Very lightly and blue tinted. After playing around I discovered that the problem was intermittent when changing the elevation of the LCD lid. I ordered NEW LCD Video Cable For Asus G73 G73JH G73JW G73J G73SW SERIES 1422-00Q00ASA http://www.ebay.com/itm/230970101150?_trksid=p2059210.m2749.l2649&ssPageName=STRK:MEBIDX:IT thinking this would fix the problem. It did not. Since then I have tried one different LCD panel and get the same results. Now the problem is no longer blue. It's just dark, very, very dark. I can see that it still sends the image to the screen but it looks at if it's the older LCD panels with the backlight disabled. I know that this does not have a backlight or inverter though. I have reinstalled Windows 7, reinstalled the drivers, reinstalled CCC. (still having issues, maybe this is related) AMD Catalyst fails to load properly. The error message is "Catalyst Control Centre: Command Line Interface has stopped working" It seems maybe there is something wrong with the graphics processor, but I currently have a monitor connected through VGA, and have also tested the HDMI output, and both work fine. I have been using and testing this system with the external monitor since I have disassembled the laptop to replace the LCD LED cable. I no longer have the old cable. Anyone with any tips? I would really like to figure this out, if not for a working laptop, for the curiousity of knowing what caused the problem. Please help. I will appreciate it very much.
