xp50 display and no sound problem

Post by azizi26 »

Hello,

I have been experiencing lcd display problems after power on. I changed the battery and then it said
" bad memory". So I did a factory reset and now there is no sound coming out. I do see names of patches and can scroll, but no sound! off course the display still dies after 30 seconds. I was searching the forum and it seems there are certain capacitors that are the culprit. I found most of the mention caps except:
C931 & C932 . Any one has any idea where these two capacitors are located? also which capacitor(s) are involved in muting circuit? Any help is greatly appreciated.
