Monitor Keeps Turning On And Off

[Batmann77]

Hey guys,

I've been having this problem for a while now, where I turn my monitor on (it's technically a HDTV, hooked up with an HDMI cable) and then it will turn itself off after about 5 seconds, then it will turn itself on after about 5 seconds again...this keeps repeating.

Usually, what I do is muck around with the brightness settings (turning the brightness down) and then it goes away. Unfortunately, this time I turned the brightness all the way down and it was still turning off and on.

I know next to nothing about the internals of monitors, so I don't even know what's going on. Maybe it's some sort of safety shut off? Not sure....

Any help would be greatly appreciated!

Regards, Jimmy.

I would definately tell you to make sure its not in power saver mode. that could be the problem. If not then it might be overheating

that sounds like a power issue have you tried it in a different outlet?

 

[Batmann77]

There is no mention of power saver mode in the menu of the monitor. If it was power saver though, it would be happening all the time. It's now working just fine, but it will happen again, as it always does.

I have also tried it in a different power outlet, and still the same issue.

the monitors psu could have a problem

I'm guessing that's not really something that I could just figure out how to fix myself...I'm wondering whether it's viable to get it repaired. A replacement would cost $190 AUD, and I'm guessing if I had to get someone to repair it, it would end up being about $100. And that's being generous about it. It's not a well known brand, so I doubt they'd just have the spare parts in stock. Hmmmm...what to do!

Monitor overheating

One reason the monitor could shut off is because it is overheating. When a monitor overheats, it will shut off to prevent damage to the circuitry inside. Causes of overheating can be dust build-up inside the monitor, external heat or humidity where the monitor is used (especially on a hot summer day), or other blockage of the slits or holes that allow the heat to escape.

If the monitor is overheating, it is best to unplug the monitor and let it cool down fully before using again. Then, if you have canned air (anti-static, for electronics), try to blow out any dust that may be inside the monitor casing. If the room where the monitor is being used is very hot, find a way to cool it down, either by turning on a fan or the air conditioning system. Wait until the room cools down some before trying to use the monitor again.

Also, if you're using an older CRT monitor, upgrading to a newer flat panel display will resolve many heat related issues in a hot environment.

try to clean it from inside
if this didn't solve it then look for corrupt capacitor
u can know if the capacitor is bad with multimeter
and i dont think it will cost 100$ if u r here in libya will cost u max 15 LD XD

try cleaning it first but if that dosnt work i would just buy a used one from somewhere you can get a decent monitor for under 100

I don't think it is a heat related issue, because sometimes it will happen straight away in the mornings after being off all night, yet sometimes it can be on all day without doing it.

I guess what's annoying me the most, is that technically it's still working....I guess it will just get too annoying one day and I will have no choice. Thanks for your replies, guys.
