Volca FM Won't Power On

Just bought one off reverb that was stated in poor condition. It said 3 of the touch keys were out, but it won't power on at all.

​

I took it apart, used some contact cleaner, and poked around with my multimeter. It at least has continuity in the switches, won't power on with batteries or power plug.

​

Any ideas or just send it back? I had planned to take it apart anyway to try and fix the touch keys.
