Here for the gear

Hi, you mentioned that you did some repair on the power supply, did you also verify that you are getting the correct voltages on the individual boards? I'm no DW 8000 expert, I've only repaired a couple of them, but when faced with a strange problem like this one, my first step is usually to verify correct voltages to the boards and assorted ICs. You may be getting the correct voltages at the PS, but some other issue like a failed passive component, faulty connector, or damaged board could be causing a voltage problem downstream.
