Does it come with any beep sound, because beep sound clarify the fault. Check it by the way.
The list is given below.
No Beeps Short, No power, Bad CPU/MB, Loose Peripherals One Beep Everything is normal and Computer POSTed fine Two Beeps POST/CMOS Error One Long Beep, One Short Beep Motherboard Problem One Long Beep, Two Short Beeps Video Problem One Long Beep, Three Short Beeps Video Problem Three Long Beeps Keyboard Error Repeated Long Beeps Memory Error Continuous Hi-Lo Beeps CPU Overheating
In this case I would recommend you to please check the connections from the monitor to the CPU or if possible try to reseat the connections again.
Also I would like you to connect any other monitor to the CPU and check if you have the same issue
I assume you have had the side panel off to watch the cpu fan spin up? if it does spin up and you get no bios beeps, then the fault is with the motherboard or CPU, most probably the motherboard. Problem sounds like capacitors blown or leaking ( have a look at the board and see if any are bulging or leaking). I've had similar issues with the motherboards that HP use, in all cases it was the motherboard at fault
Connect the monitor to some other computer, e.g., a notebook, and see if it does the same thing. If it does, then the monitor is the problem.
If it does not, then your computer is not putting-out any "video" signal, and so the monitor goes to "sleep".
If you have MORE than one VGA-output port on your computer, connect your monitor to the "other" VGA port.
Or, press-and-hold the ON/OFF button on your computer, to force it to completely shutdown.
It could be your monitor is fine. It simply goes to a cycle when its turned on and does not detect any signal coming from your CPU, it simply goes on standby mode (hence the darker image and orange/blinking light.) have you checked the computer (CPU) part?
You will need to replace the hard drive which has any version of windows operating system, or you will have to re-install windows xp on that computer. Assuming if the computer has a green light and monitor has an orange light. I've encountered this problem where I work at.
