Try to connect another monitor to verify the problem is related with your video card or the monitor itself

Hi there. Does anyone have a mannual how to use the control panel on the bottom right hand side of the screen? I've just brought this one today and the User disk that came with has nothing on it! many...

You dont need the driver disc, windows will install any driver that is needed, the disc usually contains colour temperature profiles if needed for certain graphical programs.
usually you just press the menu button and go thru the options, modern pc's and monitors dont need much, if any adjustment, but if you do want a little play around with the controls, look here.

Hi, I have an AOC LCD Monitor LM720A and I can't get it to turn on, ie a power issue possibly, I have changed the fuse and there is still no life, any help would be greatfully appreciated. Thanks Tony

anthony_salt, If the fuse you replaced is still good, then I would first check the "switch-mode-power-supply" for bad electrolytic filter capacitors. By the way, was the original fuse bad? I also highly recommend you pay a visit to YOUTUBE, search out and view the longer vid clips of lcd monitor disassembly and lcd monitor repair. FYI try a website run by another fixya guy nickname is "buddymc" and the site is They refurbish (rebuild) lcd displays of all kinds and all manufacturers. You can also check out these other sites FYI. , I hope that this info steers you in correct direction. Good luck guy. 12fixlouie bye

No display

Try Unplugging the monitor and plugging back in again,,,you dont have to shut the PC down to do this,,,if it starts backup,,,then good... if it doesnt,,then you need another Monitor.
An LCD monitor is better for your eyes anyway.

AOC 17" Flat Monitor (silver)

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.
