Help! LCD backlight has bad connection

I caught my foot on a cable the other day and pulled my eMachines M6811 onto the floor. I picked it up and it worked fine then, but now the screen backlight goes out at specific angles ... namely, the ones that you usually put the screen at.

The M6811 has a sensor built into the hinge that controls the backlight, turning it off at low angles (when the notebook is closed), rather than the usual push-button switch. Is it possible that this switch has gotten damaged and opens (in the circuit sense) at the wrong time?

Is there any way to fix this (possibly taking it apart and shorting the sensor), or is this going to be a $250 repair?

i have not done much work on eMachines but i am willing to bet that the cable that gose from the motherboard to the inverter is bad or has a broken wire so at some angles the wire is connected and then when you move the LCD it disconnects and the backlight gose out. that is the most comming cause of the backlight doing that. the cable you can try to take it out and cut it open and find the wire that is broken but it is ezier to go to ebay and search and i am willing you can find one cheap. if you do try to cut it open 99.9% of the time the broken wire is at the point that the LCD pivits and puts stress on the wires the dim switch (the switch that contols the backlight) that dosnt go bad most of the time all it dose is stick and you can fix that by cleaning it with some rubbing alcohol. i hope this helps Hellbringer

Check the stickies at the top of the eMachine / Gateway sections of this forum. Lots of these eMachines have a similar problem.
