I got a donkey kong that has loud speaker hum. I could hear it across the room. I recapped the monitor and the audio pcb. The hum improved greatly. It is very mild, and the best I think it can get.
The only problem is now I have a new sound from the speaker after recapping. A moderate sounding siren noise, like on a police car, wailing from the speaker along with the mild hiss. This siren sound is new after the recap. I tried adjusting the sound balance and volume with no improvement. Any ideas???? Not sure what sound balance is.
