Korg Electribe ER-1 mkII repair

<< < (3/6) > >>

james_s:
I wonder if they revised it and added a diode? Or maybe they were a different model, but I know they were Korg Electribe devices. Pretty sure the ones I fixed didn't have a protection diode but perhaps they did and it was overvoltage that zapped them.

feedback.loop:
It works!



The firmware is attached.

james_s:
Awesome! Nice job!

So it turned out to be the MCU and DSP?

feedback.loop:
DSP and at least one of the memory chips, maybe both, and maybe MCU as well, but it is not clear.

feedback.loop:
A couple of red LEDs on the front panel have lenses broken off. These seem to be Panasonic LN282RPX, which are obsolete.

Any ideas where to get them?
Thanks.
