Hi all,
Tried another NPN mute transistor, checked resistors even unsoldered pin 2 on micro (this is older CTC203 chassis) to let voltage divider float to 5V which didn't rise but micro will turn off mute transistor and let audio amps come out of mute. Even I took that SMD mute buffer transistor off and base voltage will rise to 5V but with SMD transistor in it only rises to .690V with pin 2 of micro unsoldered. The audio amps will mute themselves if mute pin 3 are floating or transistor in place (turned off).
Pops when TV is plugged in, will not pop when turned on and have good audio but will on turn off.
Any tips?
But I have another problem to contend with, chipper check II is balking now! Software complains can't communicate with chassis. Agggh. Needed that to reinit that 203 just in case.
Cheers, Wizard
