Batboard

HT1250 VHF full keypad stopped transmitting PL/DPL codes on all channels and confirmed with service monitor, voice audio OK. All RF functions OK. RX still operates normally and decodes PL/DPL properly. All programming is normal, reads and writes fine. Reading theory of operation, I am not clear on where TX PL is generated. Am I looking at a controller problem or replacing board? Any guidance will be appreciated.
