Hi! I'm having a problem with my AOC 5En monitor. It used to power on/turn on when I turn my AVR/UPS and computer on. But now, it always stays off and I have to maintain my press(push)on the monitor power button for it to continue displaying visuals. It all started when my kid accidentally pressed the power button on the monitor while I was working on a document. It is very difficult, even now a I type; I'm just using my right hand to type, while my left hand is holding a pen to aid me in pushing the monitor power button, so that I could see what I'm typing. So much for the push button power control...How I wish I just bought the monitor with the conventional switch type of monitor power control, instead of this useless, bugfull push button type power control like this in the AOC 5En color monitor.

The power switch seems to be damaged. Your kid probably pushed it very hard and damaged its aretation.

push it all the way & then release
