Re: CZ-101 problem - all lights on, blank display. no sound

2012-10-09 by scituate_mass

bumping my own post here.... could someone possibly let me know if there should be continuity between connector cable JH, pins 15 and 16 on the CZ-101. Looking at the schematic, it seems like they should not have continuity, but mine do. I redid all the connections and checked the traces, but I cannot find the issue. Perhaps I'm missing something and there is an internal connection in one of the ICs?

best - DT

Pins 15 and 16 have continuity on mine, but it looks like they are supposed to be isolated. I can't find a bridge. If anyone else has a unit open, could you please check this for me?
