20 Most Recent AOC CT720G 17" CRT Monitor Questions & Answers


What horizontal lines do you mean? I can think of several.

- You could have a line of dead pixels on your monitor, this would probably be caused by wear and tear of the monitor, or because it has been handled the wrong way.

- You could be experiencing 'screen tearing'. This is caused by your videocard struggling for a moment.

- If you're running an older, analog monitor, it could be because the cable you're using is getting older and needs to be replaced.

Hello all.I had 2 AOC monitors with this kind of problem also and figured out the problem with this kind of monitor. All you have to do is to unscrew the monitor and get the control control switch buttons on its circuit board. There are four switch button that control the monitor with four pins each that attaches to the circuit board of AOC, another option is to replace the switch button with a brand new  control switch button which can be bought to your local electronic shop. Now i had no problem with my AOC monitor because i literally removed those switch control buttons from its circuit board.

If you take it apart there will be a couple of bulged caps on the power supply board, that need to be changed and that will fix your problem.

If it won't power up the monitor is junk. There isn't much that one can do with a crt monitor which is considered to be obsolete.

I would recommend getting an lcd or led monitor instead of using a crt monitor.
