My friend has Dreamlink HD with the input diode D1 blown (shorted), it's a zener diode. It's hared to see but I think it's marked 929B and google is not coming up with reliable results.
Does anyone know the value of the D1 zener diode? It's on the PCB right near the power jack.
it is 929b but cant help you with any other info
the m003 didnt help either
15V ? And no resistor shorted with the diode? I'd check related circuitry like capacitors for voltage rating and I gotta say if a zener shorted most likely some other component probably took a dive too
Agreed:there's very likely damage to the "break down" resistor & the circuit topology it protects.Quote:

If it is a 929B zener then look here.
You have a big choice to look through....It should be a 1N5929B as the part type.Code:https://www.mouser.com/Semiconductors/Discrete-Semiconductors/Diodes-Rectifiers/Zener-Diodes/_/N-ax1mh?keyword=929B&No=25
