At first, I thought it may be caused by loose contact between the panel(screen) and the main board.

So, I disassembled it and check the joint.

But, It doesn't work....

I can't get a repair service from dell becasue I live in Korea... 

So, I have to fix it myself.

I want to know what make this problem get some advise.

Thank you!
