and fault repeats.

i'd try and reset the epprom again then go straight in the service mode select option 8, or you might have to fit a new epprom good luck

Ive never shorted an eeprom yet. I always replace it. For goodness sake its only a few pence for one.

Resetting the eeprom does not remove the corrupt data, either replace the eeprom or erase all data from the original. After fitting a blank eeprom there will be several settings in the service mode that will need changing to get the set working correctly, this can be checked in the service manual.
