    Same problem. Worked fine until I tried to adjust the contrast/color and it started rolling by in colored pages. Turned it off then it wouldn't come back. The computer thinks it's contacting the monitor but the screeen is black. Already tried unplugging and rebooting everything. Also tried downloading new drivers for connector but still nothing. Any ideas? It's less than a year old and should still work.

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.

SOURCE: Medion MD7317 17 inch Flat Panel Monitor

My MD7317 did the same thing until I actually installed the driver for it. My windows did not have the correct driver in it's driver base, so I found the driver online ( took a few minutes of searching) and within a few minutes of installation the monitor displayed a great colorful picture. Naturally, I had to use another monitor while I was searching. Driver is about 3.3 megs. It came in a zip format. I did not keep track of the link to driver, but it omly took a few minutes to locate it.

they normally turn off like this when they aren't receiving a video signal from the pc (same as when you turn off the pc). make sure that it is connected properly, and that the video output is activated. try disconnecting from the other monitor while its on and connect the problem monitor...if it still isn't working then there may be a problem with the cable or the monitor itself. Try another VGA or DVI cable. Hope this helps

My dell e173fp monitor has quit working. The power light continually blinks when power is applied, even without having to turn it on. An identical substitute monitor works fine on the computer system. ...


Is the power blinking amber? This is a DPMS power-save mode. With the computer disconnected and the monitor on, do you see the colored self-test block floating around? With the monitor on, computer connected, and you still have no image displayed, take a bright flashlight and examine the screen closely. If you can see a very dim display in the screen, the fluorescent tubes which light up the *background* and provide the vivid picture(sort of like a how an x-ray picture viewer works) are defective. The power light blinking may be the power supply sensing the non-functioning tubes or it could just be bad. If your display is under warranty, replace it. If not, trying to have the monitor repaired for this type of problem is almost as costly as a new one--and there won't be an active warranty on anything else that might fail. Hope I helped you.---Rick

I CANT GET MY MONITOR TO TURN ON


It could be the Monitor, the VGA adapter, or the PC itself. If you power on the monitor without anything connected to it, do you ever see anything on the display?

If not, it is probably the Monitor. If yes, it is likely the vga adapter and/or PC.

Monitor : no display and blue led light is blinking


The power supply is the first thing that the 110v electric line goes into. The invertor is the next item past the power supply, or sometimes contained within it. I do not thing monitors are a DIY repair.      First substitute a different monitor to confirm that it is, in deed , the monitor and not the video card.
