The monitor is probably on protection.
To start unplug monitor
from power and from computer and test computer with different monitor
to find out if it is monitor or computer fault.
If it is computer fault and no video signal , then test:
- Video cable.
- Video adapter on PC (sometimes integrated on motherboard)
- Motherboard.
If it is monitor fault , then the monitor is on protection.
When on protection you keep having a flashing
led on front of the monitor , and monitor turning off by itself after a while,
that indicates a fault condition.
The flashing light indicates a diagnostic state called protection.
When the Monitor goes on protection there are only two possible causes.
1The
internal circuits are jammed because of electrostatic
charges accumulating on capacitors, or because of a wrong voltage read
by the main chip on your monitor controller board. this started the
protection circuit.
2 The protection circuit detected a wrong
voltage or a broken contact, identified an internal fault and kicked in
, starting the flashing light.
If
you are in situation one, then the monitor will reset just unplugging
power cord for one or two hours,sometimes even minutes.
If you are in situation 2 , then there is an internal fault.
Common
faults
that can occurr are a blown capacitor on power board, faulty inverter
board, faulty input board, or a fault on LCD Digital Controller board.
Check also
the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you
can get same flashing statebecause of the video cable.
Try moving the video cable, and if the cable is not built in, then also try a replacement cable.
If under warranty contact the manufacturer ringing the number on the user manual
If you want to repair at your own expenses, just locate any good qualified repairer.
i have the same problem, my moniter won't turn on, if i unplug it then plug it back in, the power button flashes a couple of times then goes off.
If I unplug it then plug it back in then the blue light in the power switch would about four times then stays on solid and no display on the screen and I can't turn on the power on the blue light. I would have to unplug it again and then it does the same thing over and and over again. There is this site (monitordepotusa.com) that fixes them for $98.00 plus shipping.
I am having much the same problem. My computer is running XP and has worked fine for over 2yrs. It was working fine last night. when I tried to turn it on this morning the power button flashes at about a rate of 1-1.5 sec. if I am looking at the screen then I can see the gateway logo flash on for only a brief second and then off. I then tried to disconnect the monitor and only power it on independently to see if it would display "no signal" or go into standby. I only get the same flashing problem. I have tried hooking it up to my older computer that is also running XP and I still get the same flickering problem. One more observation is that no matter how long I leave the monitor on it will only flicker the gateway logo. This leads me to believe that it might be something with the Power Supply other wise I would see my desk top or other screens in between the flickering. Any help would be greatly helpfull.
i have the same problem and it occured after i tried to download ubuntu
