Dead Voice

2008-10-30 by George

Thanks again everyone for all your help.  

Today I tried to isolate my dead voice problem by using the 
individual outputs. 

When plugged in the individual outs, the sound would play only once  
every 8 key attacks. Is this normal with the E2?

I was able to isolate the bad voice to channel 7, which instead of 
the sound, would play only a barely audible noisy "swoosh".

I took the machine apart, removed the PSU and located the SSM2045's. 
I cleaned them with cotton swabs and isopropyl alcohol and switched 
them out with channel 8, but the problem persisted on channel 7. Then 
I decided to clean/switch out the S3528 chip as well, but channel 7 
still doesn't play.

I haven't cleaned/ reseated all ICs as ElmBeatz recommended, which 
will probably be the next thing I want to try.

I was hoping it would be one of those chips. What else can cause a 
dead voice? Thanks. (Sorry for my goofy English - foreigners..lol)

George
