Hello and welcome to the forum.
Possibly a few different issues going on...
You no longer get the LCD start message, so this sounds as though you may have overwritten the PICAXE firmware code on the backboard of the LCD display.
Re-install the
firmware directly to the jack socket on the back of the LCD.
Note: The firmware code is currently configured for an LCD, so if you’re using an OLED display then you need to change a couple of lines before re-programming the backboard.
This is the bit that needs changing, although you still have to program the PICAXE backboard with the full firmware code.
Code:
; ********************************************
; Note you must uncomment just one of these two options
; depending on whether you have an LCD or OLED module
;#define use_OLED
#define use_LCD
; ********************************************
So after changing the lines starting with #define, the OLED definition will become..
Code:
; ********************************************
; Note you must uncomment just one of these two options
; depending on whether you have an LCD or OLED module
#define use_OLED
;#define use_LCD
; ********************************************
To use the LCD you then write code which only needs to be downloaded to the 14m2, and that will have one of its outputs connected to the LCD H2 connector along with power and ground. See page 2 of the following document for further information.

Note: You MUST use an output directly from the 14m2 and NOT from the ULN2003A output. These are the connections between the 2 chips on the AXE117.
