The thing just suddenly stopped working while playing a keyboard through it. I can plug it in and hear some slight static, but no loud hums or anything that is concerning(loud).
First question being, as I’m new at attempting repairs, I was randomly checking the diodes with my DMM in diode mode and noticed that they gave around .590 V forward biased, but every one also gave around 2.5 V reverse biased. These were the 4 that lay right beside each other so guessing they are part of the power supply. I was expecting each to show an open circuit. I tested them in circuit. I guess I’m doing it wrong?
When plugged in, the “ON” led glows, so i guess at least some power is going somewhere.
Once I figure out how to correctly test the aforementioned diodes, could I have a suggestion as what to test next?
