Well its either the motherboard or the video card issue.

you will need to replace one of those and most likely will be the motherboard

Marshall sd monitor wont power up


Here's some tricks I would try...
1. Verify the monitor's power cord is plugged firmly into the wall outlet and the back of the monitor.
2. Verify the monitor cable is firmly connected to the computer and the monitor.
3. Verify that you have turned the monitor power switch on.
4. If the power light on the monitor is not on, test the wall outlet (plug in a light or something you know works).
5. If the power light on the monitor is not on, try a different power cord.
6. If the power light is on and yellow or orange or flashing, but nothing displays, or the display is incorrect, borrow a monitor from a friend. If that works, your monitor probably needs replaced.
7. Also, you could try your Monitor on a friend's computer. If it doesn't work, your monitor probably needs replaced. If it works properly on your friends computer, the problem may be with your computers video output port, motherboard video chip (or video card, if you have one), or drivers.
Good luck.

HP w2207 no vga input signal, no dvi input signal monitor goes to sleep


There is no signal coming from your PC.
excuse some of the solutions as sounding dumb, but we have to explore all possibilities.

Check the power cable going into the computer
Check the power input disconnect switch on the back of the power supply and make sure it is on
If the pc is plugged into a power bar, make sure it is turned on and the breaker isn't tripped
press power on the PC and make sure the lights are coming on.

now for the solutions that may actually help.

disconnect the power from the PC
if the video is on a card, remove and re-seat the video card
hook the power back up, connect the monitor and try again.

the CMOS on the computer may need to be reset.
I hate totally clearing the CMOS, so what I usually do is remove 1 stick of ram and power up. If the system is alive again, power down, put the RAM back in and power back up.
If that doesn't work, turn the system off, put the CMOS jumper to the CLEAR position for 15 seconds, put it back to the Normal position and then power back up.

Basically, if the monitor works on your friends system but not on yours, the the problem is your system, not the monitor (assuming it isn't working fine til it gets into windows...if that's the problem, you have a driver or configuration problem)

Monitor stays blank power light blinking


In this case if you monitor say no input or no signal it means the monitor connector cord are not connected properly to the motherboard. Or if you have a video card you need to plug your monitor connector to the video card. Because if you a video card and the monitor cord are connected to the motherboard the monitor will not be display. So check the monitor connector if it is correctly connected.

The screen will not come up but gave this message 'No input signal, go to power save


To isolate the problem, you need a friend with another computer since right now, we don't really know if the video section (or card) of the PC is at fault or the monitor.
You need to swap displays with someone so you can be certain what is actually not working.
The monitor is obviously capable of scanning inputs for a signal and not finding one.
