Hanns.G HG281D Monitor - Cycles on and off randomly

[mooses]

This monitor is 3 years old now and the problem I have with it is when it goes to sleep (computer off no video signal) it will sometimes turn itself on (LED Blue) and then go into standby (LED Orange) and then switch off (No LED light).

It'll just cycle through that while it's plugged in and left on.

However when I want to use it, if the LED isn't blue at the time it can take up to 20-30 minutes for it to turn on by itself.

Once the monitor is on it works fine and there are no problems until I turn off the PC or the monitor goes to sleep.

Any idea what the problem could be? I'm going to open it up soon to take some pictures but I just need to get me a temporary monitor to use before I do.

Likely dried up caps with high ESR. As the lcd warms up, the cap's ESR drops allowing the circuit to work. See
