Why I hear a hum after turning on my Sony Trinitron CPD-210EST9 Monitor?
The hum heard right after turning on your Sony Monitor is the sound of the auto-degauss cycle, which automatically degausses the monitor for 5 seconds. If a second degauss cycle is needed, allow a minimum interval of 20 minutes for the best result. This humming noise is not a malfunction.
