Korg DW 6000 not powering up

Post by radek tymecki » Wed Apr 05, 2017 6:47 pm

My DW6000 suddenly stopped working. All voltages on PSU are ok. There is no sound, nothing is also displayed on the screens. i can only hear a click after powering up and that's it. fuse is not blown

Got manual?
Reseat all connectors. And see that EPROM sitting correctly in a socket and all other things correctly in a socket?
If thats ok then - does the CPU gets generator signal and the RESET signal?

i have no oscilloscope so it's pretty hard to say about reset/generator. any chance to measure it with a meter? sockets are ok. eprom sits nicely, sockets also.

What you can check still is that there are no "cold joints" or cracks in the soldered joints or circuit traces.
If after that you still have not found somehting then in this case it is beyond multimeter. It has something seriously wrong, so do not tinker with it and leave to someone who has the all needed measurement instruments and skill.
