Korg Poly 61 Project Machine

“The unit powered up fine but the keys would only make a popping sound. I had read about the bad internal batteries so I had a new one installed even though the old one had no signs of leaking anywhere. That did not fix the problem and that is about as far as I can go with the repair without knowing how to test for problems. I am selling the keyboard as/is since I have no clue what the issue may be. If you would like the old battery I can enclose that with the keyboard.” Click here to search for synths on eBay
