I bought a $5 replacement power supply for a used monitor from amazon.
It's the correct model, and it works, but it makes a very high pitch squealing noise. When I put it up to my ear, it sounds like radio static.
Is this the sound of something inside arching?
Am I running the risk of damaging the monitor or starting a fire?
Can I open this thing up and fix whatever is making the noise?
NOTE: It makes the same sound when it's plugged into the wall and not the monitor, but the noise is much quieter.
As always, any help is appreciated.
