Update - I unsoldered the RL401 and RL402 relays. I used some DeOxit D5 and a piece of paper to go back and forth on the top and bottom contacts of the relay. There was this bodge wire installed on the back of the board. It looks factory as no traces lead out from the lower left pin on the relay. Upon re installation, there is still no audio coming from the player. However, I can hear more of machine's noises if you will on the audio output so I believe this may have been part of the problem.
Is it possible that the audio/control head is out of alignment? I don't have a scope to check for any waveform on the head output.
I will try to interject an audio signal in place the output of the audio head and see if there is some circuitry that is stuck in a mute mode possibly.
I have a feeling it is a simple fix hidden somewhere.
