[QUOTE="rustyk123, post: 999494, member: 99923"] Ok, first off I will mention I am a laptop tech and repair every issues day to day. Based on what you are saying i am thinking it is a screen or inverter. This is one of the most common problems with laptops. To test this look at you screen very carefully and look to see if you see the picture extremely dim. another way to test this is to connect a monitor to the computer and send the video to it if it comes up the is a display problem. You can check your cables but you are only going to possible find a problem with the inverter (small circuit inside the hinge clutch) cables. If this was a problem with a lose video cable the screen would be white. Hope this helps you. Let me know if you have any questions or your results. [/QUOTE]
