Roland D-50 Acting Strange

[typhoolin]

I am the original owner of a Roland D-50 synth. It is truly a great sounding synth from 1987 and I was hoping to use it LIVE - however I am now noticing that it will suddenly "drop out" when I'm playing and then it will either get stuck on a note - or it will go completely silent.

I have already tried opening the unit and replacing the Sony CR2032 battery and that seemed to help for about 2 weeks and then it started acting up again. Not sure what is wrong - but it appears that it is no longer able to withstand the pounding of rock-style keyboard and it just fails when I play it - regardless of whether I'm playing for 2 minutes or 20 minutes. I have to turn it OFF - then ON again to get any sound.

The sounds that I do have are on the Memory Card.

I have the original memory card w/ 64 Roland factory presets.

Any advice is certainly appreciated!!!

I would be looking for cracked solder connections on the power supply pcb, especially the voltage regulators.

Okay - thanks. I can give that a look.

I would resolder the MIDI jacks. And for that matter, try a NEW MIDI cord.

To play a note via MIDI, the keyboard sends both a note on and then a note off signal. If you play a note and hold it, and yank out the MIDI cord, then the receiving end never gets that note off signal and you get a hanging note.

And while you are checking, always check the solder on the regular audio output jacks as well as the pedal jacks.
