Hey guys,
while looking for a soulution für my XP 50 's "NO-DISPLAY"-problem I checked out this board and I'm very keen about the good explanations and information in here. Thank you a lot!
I solved the problem changing the caps C901, C902 and C65.
Now my Display is fine again ;)
But I do still have problems with the audio output. There's a continuous humming sound on both jacks.
Furthermore, when playing the synth, the note 'd' is much louder than the rest.
Does anyone know about this problem?
It seems very hard to me localising the audio output area on the mainboard without any documents like manual, service manual or schematics. Unfortunately, I don't find such documents somewhere online.
Does maybe someone of you guys have such documents? I'd be very pleased if someone could email me such documents: heavy_volxmusic[at]t-online.de
Best regards from Germany,
Chris
