Re: Cannot turn off monitor
It is problem with power settings. Start/Control Panel/Power Options -- and then pick a Power Scheme from the drop down list and make whatever modifications you want to the settings that power down your monitor

Have you tried checking with another monitor. Meaning that if the second monitor does not come on then the problem is with your computers mother board. But if the monitor other monitor you check it with comes on then of course it is your monitor.
Certainly, if you jumper the connections to see which ones turn the monitor on or off, then you can go to an electrical supply place and get a micro switch and wire it in in place of the power button, or perhaps find a type that is flat that the power button can press. What you need to determine is if it is a push-on, push -off type switch, which always stays on or off depending on position or if it is a momentary interrupt switch where the button pressed momentarily turns it on and then releases and a second press connects the circuit to turn it off. You can do this by testing with your jumper wire, attach it and if the monitor stays on when you remove it, then goes off when you attach it again, you need the second type switch, if it goes off when removed, you need the always-on always -off first type switch. .
Not sure if this is your problem, but I have seen this with another Dell monitor on three separate occasions. The solution I found was to turn off at the wall power socket, unplug at the wall socket, plug back in, turn on at socket etc and everything was fine. Guess something hangs up somewhere.
sounds like a burnt or a cold solder around the TRANSFORMER section of the power supply , I suggets if your handy w/ tools to open the monitor and inspect the PC BOARD for any burnt or cold solder THAT not making the connection , hope it helps AJ
while the monitor is still powered on, but with the LED flashing, unplug the monitor from the PC. press the power button, and the monitor should go off, now plug the pc back into the monitor. Turn the monitor back on and it should work.
Occasionally this will not work for me, but if I repeat it it normally works
Hope this helps - my problem is intermitant so it may be different to what u guys have
