Question about Audio Players & Recorders
My Boston Subwoofer would not power on. I took the unit apart and found that the Zener Diode located at ZD3 on the power supply board is fried. I'm need to know the value so I can replace it. Any help would be fantastic.
ZD3 is a 18v zener. Also check the surface mount resistor on the back of the board that is attached to ZD3, I think it is R9. Should be 10 ohms. This resistor sometimes opens when the diode goes short.
