Somebody please help me! I have this machine functionally working but every time I think I am done and put it back together, something breaks! I have been working on it over a year! (With a long multu month break in the middle however) But I started back up again a couple weeks ago and its the same old thing it seems to like to do. Fix it, put it back together, new issues. Anyway...
The indicator lights for the two memory lights and the zero return lights are not working. The record indicator light wasnt working but I finally figured out it was a ruined solder joint underneath the light. I even tried tracing voltages all over, looking at the service manual and such. I even ordered a new Mitsubishi M54517p darlingotn transistor array to replace the chip U507 on Control board A because I saw the voltages not getting through the chip on the channels where the lights were not working, and the voltage was getting through on the ones for the play and pause indicator lights which worked. So I am stumped.
But now a new issue unfolded after I fixed the record light of course! The same segment on each number of the display stopped working and I do not know how to fix that either. It is the bottom right segment.
Thank you!
