why does my monitor randomly turn off?

August 15, 2017 at 23:58:29
Specs: Windows 10
So this issue has been ongoing; my monitor (desktop) would randomly shut off while starting computer (not just to orange/standby, but off completely) the only way to get it going would be to try unplugging and replug the power to the monitor, this could take up to 30 times. It would also happen if the computer went into sleep mode. At the time, i assumed it was the monitor so bought a new one (Acer), and it continued to happen, then found out our tower was old and having problems. Got rid of that and bought a new tower on the weekend, set it up to old screen (12mths old) and it has started happening again?? Anyone have any clue what the issue is?

Does the newer monitor have the same problem when connected to the new computer?

Presuming no, then likely the power supply in the older mo ntor is failing. How olde is that monitor, and also make and model?

thanks for your reply.
Yes it does, not as bad yet (will only need to unplug once or twice) The monitor is about a year or so old, and the tower is only 4 days old.

The monitor is an Acer LCD not sure about other details

Are the monitors plugged directly into a mains socket - not fed power from the computer (which was an option in the olde days when desktop/tower systems had mains output sockets)?

Are you using the same mains socket each time for the monitors?

What happens with each monitor if it's simply plugged into mains outlet and left sitting switched "on" - but not connected to your computer?

Are you using the same cable between the monitor(s) and the computer; or do both olde and new monitors have integrated video cables?

the power is plugged directly into the wall socket. (the monitor has it's own)
I only have the one monitor running (bought the new one as this was the previous issue i was having). And the tower is brand new.
I will try running the monitor to power on it's own now and see if there is a problem.

If you are using the same cable between the monitor and the computer, try a new/different one.
Try a different wall outlet either by moving everything into a different room or using a 3 prong grounded power tool extension cord (testing purposes). If it works well from a different outlet then there may be a problem with the outlet or the wiring to it. If this is the case, get a plug in outlet tester and ultimately a licensed electrician to fix it properly.

You have to be a little bit crazy to keep you from going insane.

i'm not sure if the cable is a new or old one...i can't remember if i got a new one with the monitor? Could look at trying that.
We have recently moved house and the issue is ongoing, so i am thinking it wouldn't be the power source..

Normally new monitors arrive with at least a (new) mains cable. They don't always arrive with the necessary cable for the display sogna/input.

Not entirely unknown for new mains cables to be faulty; no harm to try a known good one?
