Monitor turns off on its own, then won't turn on
This has happened three days in a row (in the morning):
- I turn on the monitor - The light goes on - I turn on the computer - It sends a "sync" signal right before it loads the bios - Monitor flashes briefly - Then it turns off. It does NOT go into sleep mode, it simply shuts off. And won't power on until after one minute or so. I must boot down the computer, unplug the monitor power cable for about one minute. Then connect power, turn on monitor, then it usually works. However, this last time I had to do it twice. Bad circuitry? |

If not it's most likely a driver problem. Go to Device Manager, delete the video card(not disable) and reboot. That should straighten it out. |

Kind of sounds like the power supply in the monitor might be on it's way out though. -Dave |

The bios screen doesn't even post before the monitor shuts off. That's
why I think it's the circuitry. But it does flicker for just a second. Perhaps the video card is sending something abnormal and the monitor shuts off by way of a self-protection mechanism?

Not likely to be a driver problem as it doesn't get as far as Windows. As it doesn't seem to be booting properly, I'm not sure it's anything to do with the monitor. I would guess at the PSU in the PC being flakey, it might be worth trying another one in it, if you have one avilable. HTH SteveH |

iiyama monitor with both BNC inputs and a VGA socket ?
If yes, looks to be quite common. Try the other set of connectors instead. monitorhelp a écrit dans le message news: ...

Well, I tried that and it's still turning off. Tomorrow I will try a
different computer. Could be the video card. Aldo Larrabiata wrote: iiyama monitor with both BNC inputs and a VGA socket ? If yes, looks to be quite common.
