Discussion about the Korg PolySix synthesizer

I have problem with my korg polsix- the  battery problem. I have tried 
to clean the klm367 board and replaced the ic30 and ic31 and also 
changed the battery/ not working after this . I'm not so good on 
electronic so I can't do anymore than this. I wonder if anyone can do 
the repair or have a fully working klm367 board to sell.
