“”Problem:
1. No sound coming out of the phone and other outputs
2. The battery needs to be changed
3. MIDI Channels need to be checked to see if it’s working properly
Action: Verified no sound out of any outputs. Replaced (1) 3V battery. Resoldered the power supply and the contact bridge of the keybed communication boards. Resoldered multiple capacitors and connectors. Performed hard reset. Attempted to reload some tracks from the library via MIDI, but the motherboard did not accept the communication. The motherboard or the keybed scanner could be damaged. Could not find schematics or tech support. Need another unit to compare against to solve cost effectively. The customer decided not to continue with the repair.”” Click here to visit listing on eBay
