I have dual AOC i2553ph monitors. One day I came into work and notice one of them had a single vertical white line moving slowly back and forth across the screen that looked like a scan or radar function. I reset the monitor from the OSD and all is well again. Use "Extra > reset" from the OSD on AOC monitors.

    that is the correct OSD page
    and is covered in the free manual if you RTM
    these monitors are buggy firmware
    some do not like having AUTO input selected.
    use manual input selection./ OSD

SOURCE: two vertical lines across screen

This is a common problem when LCDs are subjected to strong shock. Your internal circuits are damaged The panel itself may not be cracked but there is internal damage. I know of no cure or repair possible other than to replace the panel assembly.

Your monitor seems to be broken and a repair may cost more than a new one depending on which country you live in. There is nothing you can do to repair it and I strongly suggest you do not attempt to open the monitor to service it yourself, the coils inside the monitor will remain charged with 10000v or more even after unplugged and disconnected for a period of time. I am sorry to say it is time to replace it. Good Luck!.

1.Make sure all the connections are secure.
2.Try attaching the monitor to a different PC if possible, to determine if its the monitor or video card.
3.Your monitor might just be going bad

Sorry this wont help you much, but may put you out of your misery trying to repair it.
The LCD panel has failed. In particular the driver tabs that connect to the physical panel have failed and there is no way to repair them.
The only soloution is to replace the entire panel, a cost that would be close to if not more then a new TV of the same size.
I would put it on Ebay for parts (powerboard, logic board etc), and use the money towards it's replacement.

SOURCE: (external monitor AOC LM765 flickers white

Hook up that monitor to another laptop or computer. If it works then its an issue with the vga port on your laptop. If the monitor still shows those lines then you know for sure the monitor is bad and it will have to be replaced.
