Time to get a new one I think. Sounds like there's something screwy with the power supply, but there's really no means of servicing most monitors. You just throw it out and get a new one. If it's under warranty you can probably get a replacement, otherwise start looking at store ads and online.
my pc lcd monitor takes ages to switch on, eventually it will but not after 5 mins or so.
the light on the front blinks every now and then but it is quite annoying,plz help me find the problem and if my monitor is breaking !!!
