I have a GP38-2 20-2663-1 PS2 3 volt. See video. The Buzzing is coming from the big black relay. I can put my fingers on it and I feel it vibrating. So no it is not coming from the speaker. Thoughts?
No lights or sound in conventional just the buzz 12 volts applied. In DCS, power on and just one buzz and no engine found.
Fixable or board need replacement?
