Tip & How-To about Computers & Internet
When I move my notebook's screen it starts flickering.
Diagnosis & Solution
This can be an indicator that the wire bundle running through the LCD screen hinge has been compromised. Some wire has frayed apart and is making intermittent contact with itself or the lid movement is causing the wire bundle to pull on one of the video connectors. In order to fix this problem, you will need to remove the notebook's front hinge cover & check the bundle of wires connecting the motherboard to the LCD screen. If this bundle of wires is damaged, then you will have to get it replaced. To find out if there is a break in the wires, you need to remove the video cable, and perform a continuity test with a multimeter.
Another possibility is that the video cable could have become slightly unplugged either on the motherboard side, or on the inverter board side. If plugging in the connector on the motherboard side doesn't cure the problem, check the end of the video cable connected to the inverter board. The inverter board is usually located behind the display bezel of the display panel assembly, or beneath the notebook's front hinge cover.
