Please search on bottom side of pcb for location number "IC 601" (white writing on pcb) and tell what is there - ie. soic8 chip or just empty pads?

If the pads look like they've seen a soldering iron before - ie not virgin - you need to find replacement c128 chip and suitable dump. Good idea to post your Panasonic ref number like: CQ-JG...........

You dont have the old radio to pull the eeprom from that and put to this buddy?
