Vintage Synth Explorer Forums

i have another p6 that had battery leak problem. i've repaired bad traces and checked cpu, ic30 and 31 few times pin by pin and everything seems to be ok. every function works, there are no problems with sound editing, saving etc. but still there are 2 problems:

1. bank A, D, program 1 and 4 are lit all time. bad connection around ic30 and 31? or what?

2. there is little vibratto on sound. it can be fixed when i set modwheel to 0 and level on panel to 0. but when i switch patch the vibratto appears

help

та же самая проблема,мой сейчас в ремонте,надеюсь спасут.

ok i've found that cn10 was a bit damaged - pin 1 and 4 had no contact. after fixing it D4 problem disappeared. but A1's leds are still on.

mod issue fixed - removed cn06 pin 2 and soldered directly to r9
