AOC CT720G (Black, Silver) 17" CRT Monitor driver


The monitor probably doesn't require any special driver. There are drivers for your motherboard video chip, or if you have a graphics card. If you need to make adjustments to the monitor, the manual is here... http://www.manualslib.com/manual/8152/Aoc-Ct700g.html

AOC color monitor model 5En...during power on all led lights blinks then stops blinking without display action. all led lights on no more action observed.


actually if u repair an aoc monitor alone without getting connected to cpu once u switch on the monitor all led's will lit on ( green light ) it will remain on situation until u connect the vga connector to cpu that's the time led's will lit off and only the power led will remain in green condition.some aoc 5en once u power on power led is in green condition and if not connected to cpu it will be in orange condition.hope u get some idea but i am not sure if it will work with ur monitor. but as long as LEDs lit on i think no problem with ur monitor.

Power Light Blinking & Black Screen


A blinking blue light indiactes that your power-inverter board is not putting out what it should. It needs an overhaul which may be a simple as changing out the capacitors on the boards.
It could go beyong that to transistors or even a bad bulb.
It will have to be opened up to do that.
A picture may show visual signs of damage. If you can take one and email it to me , I'll take a look.

Aoc 5en no display


I alreeady encountered this problem. I fix it temporarily.... I just turn it off, Press all the Function btn and the recall btn, then pres the On btn... wait for 2 sec then release the func, recall btn. Then I already able to use the PC for about o hours without interrupted signal (on/off). I call it temporary fix because whenever you turn off the Monitor, you have to do the same process again..

Try it it can help.. Thnaks.... If you already find solution , maybe you can share it to me too .. Thanks..

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.
