    My Samsung Syncmaster 170MP combo TV & PC Monitor that I bought in 2004 just went blank after turning the computer off. Now I have a black screen and green blinking light, but can't turn it off or on. Any help will be greatly appreciated as Samsung just suggests buying a new one. They're not much help and I won't buy another Samsung product, that's for sure.

Make sure that your computer isn't going into Standby or Hibernate mode. You can test this by briefly pressing the power button and wait to see if the screen comes back on.

Dell E173FP Monitor requires unplugging/plugging back in to wake

Perhaps your computer is hibernating instead of going into standby which takes a little longer to wake up from. While you are playing plugs and cables it give it enough time to come out of hibernation.

When the computer is in this mode the USB ports turn off which disables keyboard and mouse so the only way to wake up the computer is to press the power button on the computer itself.

One tell tale sign a computer is in hibernation is that the power light on the computer will slowly blink.

I hope this helps.

Dell E173FP Screen blinking red, green, blue, white

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 occur 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 state because 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.

Monitor keeps hibernating, can't make it stop, pixel issue.


I think this is more of a problem on your computer instead of the monitor, ofcourse you could try another monitor and see if the same happens. I suspect your computer goes into standby or hibernation on its own, and it does work fine if you reset the computer right?

if you go into power management again, disable or turn off hibernation completely, its on one of the pages.
Make sure its not set to standby, and also disable your screen saver.

Right click on desktop - properties - then screensaver. turn it to none.

Also you could look into the computer bios and make sure its not set to standby or hibernation from there. thats unlikely but you could check.

how to get into bios.. depends on the computer, right when you turn it on, on one of the corners of the screen you will get a message, press button to enter setup or bios. press that to enter bios when its presented.

look around the bios and poweroptions.

Let me know if you need anything else.

Please disconnect the Monitor Data cable from Computer.
If you see Dell Colored bars, it means, monitor is working fine,
If still black, please ask for replacement, since Monitors have 3 years of warranty if not purchased with the computer.

Now connect the cable back to computer and turn the computer off by holding the power button on computer and turn it back on...

Blinking Green shows that computer is in sleep mode......

Hope this should resolve the issue.

According to the manual for "POWER/STANDBY indicator is blinking in red":
  • "The temperature inside the main unit has become too high and has activated the protector."
  • "Promptly switch off the power of the main unit ans wait until the internal temperature drops."
  • "If the monitor becomes too hot, the overheat protector will be activated and the monitor will be turned off. If this happens, turn off the power to the monitor and unplug the power cord. If the room where the monitor is installed is particularly hot, move the monitor to a cooler location and wait for the monitor to cool for 60 minutes."
