Hi guys, I have this mitsubishi model CS-2651R no audio, i dont have a print
for this but have checked sound board and cant seem to find a good audio
sygnal. it seems like the audio is stuck on mute. Still, cant seem to find a
good audio waveform even on the main board. On the sound board(mitsubishi
pt#930B15901) at ic3A2(TA7630P/NTE1576)
pin 2 and 16 are audio input, no signal. i know the amp curcuit is working
by bypassing this ic and injecting a 10khz. sygnal to amp, speakers work
fine and has audio. could this ic be bad? Also there is an ic on the main
board ic101(la7520/nte1728) and has audio driver curcuit in it and also
controls muting. has anyone seen this go bad.
is there something i'm missing or should i change these ic's.
Any help?
Thanks much in advance,
Mike
