I am unfamiliar with the STM32F103C8 48pin chip that operates the LCD
Does any USER know where I can get information to an "EEPROM" contained in the STM32F103C8 48pin chip ?

Could be the error related to the external EEPROM (U2-24LC32A)?
In this case, you could check if it's correctly soldered to the PCB

Hi
Run the unit from a more stable and better 9v source could just be just your battery is not too good before you get too involved

@mshen:
Please try the new firmware (version -111) before further hardware troubleshooting. This issue could be related to the bug that the version -111 fixed.
