Been checking this beggar after a major clean up of a spill into the set that ate up some TACT switches on the front. Switches have been replaced. Now for the gory details:
Pressing power get nada. No click or any change in the 'signal' to relay Pre-Driver.


Pressing any TACT switch gets pulses on both sides of the switch and appears on all other TACTs not pressed. No pulses seen when no TACT is pressed.

Pulses are seen going to the Relay Pre-Driver and goes into relay driver and 14 volt pulses. Pulses going into Pre-Driver is 5 volts P-P.

Regulator +5 is clean and on the mark despite seeing a weak pulses going into a gate of regulator.

14 Volts is also clean.

Methinks I am dealing with a bad Micro aka QA01 and/or EEProm QA02.

Appreciate a kick in the right direction if I am wrong in the above assumption.

BTW , the CF27E50 I downloaded was corrupt and used a CF27E30 which was awfully darn close for me to get this far.

Best and Thanks: Eugene
