For my 917Sw 19"w, I just ran into this problem. It was kinda annoying, but after looking around then remembering to look in the instructions, I found I just had to turn off the monitor, then hold the left button as I turned the monitor back on.

Except that fiddling with buttons . . . uh . . . works? It's not even a mistake or error. It's a function of the monitor that you can turn off by 'fiddling with the buttons.'

I ran into this problem too, it was holding the menu button down while turning on the monitor that fixed it! All good now!
Thanks.

Posted on Oct 26, 2008

It is not at all a problem related to desktop or video card. It is most certainly a problem within the Monitor itself and will probaly need a change of some IC which can only be done by AOC service personnel (If under warranty) or by other skilled repairmen. No point fiddling with buttons & cords.

SOURCE: MY MONITOR AOC LM725 GOES ON & OFF REPETEADLY

No, all you need to do is reset the monitor to factory settings. I fixed mine that way.
If your monitor goes off every 3 seconds (like mine did) you have to be fast or siwtch it on/off few times between the steps to get it fixed.

- 1st. unlock the OSD if when you press 'menu' you get the message 'OSD Locked'. To do this switch off the monitor, and press 'menu' while you switch it on again.

- 2nd. Switch it on, press 'menu' and quickly 'press '<' (left) twice and 'menu' twice to get it reset.

- 3rd switch it off and on again and if still goes off after 3/4 secs, try to reset it again.

I reset mine and it is working find. Before it went blank after 3 secs.

I just tried this because I did not understand why if it was a hardware problem I could see the screen for 2/3 seconds and if pressed on/off it came back, it made no sense as a hardware problem.

SOURCE: On Screen Display (menu) is Locked

Hi there - I read in another forum to use the left button instead of menu. Give it a try - power off and hold left button while powering on.

I'll cross my fingers for you :)

Osd unlock


To unlock the OSD (onscreen display control), turn off the monitor and then press and hold the Menu button on the monitor. Then press the power button to turn the monitor back on. Do not release the Menu button before pressing the power button. This same step (holding the Menu button and then pressing the power button) enables the OSD lock. The menu button is the top button on the right side of the monitor (on the bezel). The power button is the bottom button of the group. AOC has the documentation for the 2036sa here: http://us.aoc.com/monitor_displays/2036sa . See page 20 of the User's Guide for the OSD lock procedure. The picture of the monitor buttons is on page 19. The guide is available as a PDF on the AOC site. Note: you will need Adobe Reader or a similar program to read the file.

I hope this helps.
