Issue: The mechanism picks up and plays the first record (R8) no matter what selection is made. Also, while scanning and a selection is made, the mechanism immediately plays what ever record it's near.
The jukebox was selecting fine. The issue appeared after I replaced the TJU3 with a RCSU3 and hooked up a wallbox. Using the wallbox to select a record exhibited the above issue. I then reversed my work, replacing the RSCU3 with the original TJU3 but the jukebox continues to exhibit the selection issue described above.
I re-seated all the connectors with no improvement.
I figured something happened when I replaced the TJU3 with the RCSU3 but have yet to figure it out.
I have the manual and can start the trouble shooting guides but was hoping someone could deduce what happened between hooking up the RCSU and then reinstalling the original TJU3 in the TSU5. (Previous fix: replaced both AO2s, 6X4, 6X4 socket, C515, C514, R518).
Thanks for any insight! jerold k
