Re: QMX+160-6 ceased powering up #QMXplus


 

UPDATE:? i received my 2.1 mm connectors.? I know they are smaller as my DMM probe does not go inside it as it does for what was probably a 2.5 mm.
?
I checked for voltage, and there is voltage in a bunch of places.? No reading at Vcc nor Vdd.? The diodes i checked seemed ok, but there is something weird:
?
I check for voltage at Q105 and Q103.
?
I do get 13V on one pin, and about 12.5V on the other.? However, on the back tab of 105 i don't get a reading, but i DO get 13V on the back tab of Q103.
?
Please advise,
?
