Horizon SPF-20A Initialize issue

Hello
Please, can anyone help me with SPF-20A Initialize issue.
When we turn the machine on, software initialization starts and display message stay Now Loading...
We thought that the program might have been deleted from the EPROM modul!

Thank you.

 

Hi sir;

1) Review the power supply for Vdc if there are in Tolerance.

2) See if the Display has Battery, and measure the Voltage if is low, replace it immediately, clean and tight the ribbon or flat cable or broken wires.

3) Finally, see if the IC including EEPROM, are clean or oxide and use clean contacts cleaner. and tight very well in the bases. if the machine is have the same problem, please Reset the Cpu or Microprocessor.

 

Thanks.
Everything seems to be fine.
Does anyone have an EEPROM program / software for this model.
