I have a Norwood 17" LCD monitor. Lately it's been having this problem:
When it has been turned off for a length of time when I turn it on the it doesn't come on and the indicator LCD flickers somewhat randomly. If I unplug the VGA video cable sometimes it seems to help and stops flickering in which case another press turns it on solid yellow and reconnecting the cable turns the monitor on. Or sometimes another push will turn the monitor on and it gives the no signal indication and it will be ok when the video cable is reconnected.
However sometimes nothing works and I have to wait a few minutes for it to stop flickering. During the flickering period the screen remains off and no amount of pushing or pushing and holding any buttons help. When the monitor does come on it's perfectl normal and there's no flicker or any apparent issues with the cold cathode bulb. (But that doesn't mean there couldn't be some issue with trying to start it.) Thus far it always eventually comes on.
I tried running the monitor off a different 12 VDC source but that made no difference. This is a cheap monitor and it's not the end of the world but since it works perfectly when it does come on it seems a shame to have to junk it. I guess I can open it and see if there's anything obvious (doubtful) or if there are any capacitors back there that could be showing premature aging from heat vs. lowest quality grade and replace them on speculation.
Any ideas?
