Re: buzzing sound from monitor

The buzzing starts after about 20 minutes, regardless of how long the monitor had been off. Shutting off the monitor for 1 second fixes the problem for another 20 minutes, so I do not think it is a thermal issue. Also, the buzzing sound is not gradual, it comes on all of a sudden.

I have a Princeton Graphics Arcadia 35 inch CRT 4:3 HDTV. I am posting this in the computer display forum because it also has 2 VGA inputs and supports 1024x768 (I am using it as a TV and HTPC display). The monitor is about 5 years old, it served as a monitor in my NOC at my office. We were getting rid of them so I got it for free.

The problem is, after about 20 minutes, it starts to emit a humming sound. The sound stays the same level no matter how long I leave it on after that. Power cycling the monitor resolves the problem for another 20 minutes.

The good news...
