Is My Monitor Going Belly-Up?

[BuzzU]

It's moaning and groaning like a sick cow. It works and looks perfect otherwise. Is it going out?

[shonist]

try turning off and on the fridge.

[BuzzU]

You need to explain that one to me.

I`ve heard monitor noise can be caused by failed grounding in the speakers.

I`ve heard monitor noise can be caused by failed grounding in the speakers.

 

That would lead to the first important question. Does the monitor have speakers? If yes, are they muted?

[BuzzU]

I don't believe it does have speakers. Now it's being quiet. I'll have to see if it does it again in the morning and that will tell us it does it before it really warms up. It's shut off every night.

if it's making wierd noises it's usually because there's something overheating/failing could be a bad capacitor or because a transformer is vibrating, the transformers have metal sheets instead of solid metal cores, sometimes one of the plates comes loose, and then the magnetic field from the coil causes the loose plate to vibrate... or if your monitor isn't an LED backlit one, one of the lights could be failing... there's many things that could be wrong...

 

the fact that the noise goes away when it's on for a while tells me it's an electrolytic capacitor that's failing, but no real way to tell without checking... if it is a bad capacitor, eventually it will short and blow a resistor or fuse or worse, blow an IC

Ok, thanks. Hopefully, it will last long enough until I can afford to buy a new one. Always something. Bear hunting season is next month and it's sucking up all my spare cash.
