Raiden II Repair Logs
Symptom: Dead/Missing parts
Replaced missing YM3014 sound DAC IC with one from a parts board. Board would come up but caused the monitor to squeal like a pig. Had bad vertical and horizontal sync. A physical inspection showed a popped pin on one corner of the surface mount custom chip at location U0135. A closer inspection revealed many pins with broken solder connections on that IC. Resoldered the surface mount IC to fix.
