Bally 5500 Error code 30.9

[TTJACKPOT]

All of a sudden my 5500 came up with error code 30.9 --or a 30.7  (Hopper Overpay) when the machine tried to pay out quarters--Tried Ram Clear still same code when I try to cash out credits--Could this be a Hopper issue with software?? Need help--Machine works fine until I try to cash out my quarters--Oh the Hopper does pay out manually so I know there is no coin jam--Anyway if someone could give me some advice I would greatly appreciate it--John T

OK I swapped out MPU Board and now Hopper works just fine--Must be a bad chip on the other MPU--does anyone know what chip controls the Hopper on the MPU Board--Thanks again: John T

This has been resolved--Hopper is OK just too many coins that caused it to jam up--works great now--This Post can be deleted---Thanks again
