Discussion about the Korg PolySix synthesizer

Hello all,

I am trying to narrow this one down and could use a little help. I am 
working on my third PolySix battery repair for another friend. This one 
when powers up lights all then Bank C Patch 3. These do not go away 
when you select another patch/bank. I have gone over my trace repairs 
several times now and can't find the short. 

Does anyone have an idea on which trace would cause this? or is another 
issue a possibility?

Thanks in advance
- Daniel
