hi,
had another try,
got this error in syslog:-

Apr 13 17:14:28 moode systemd[1]: Stopped OLED Display Service.
Apr 13 17:14:28 moode systemd[1]: Starting OLED Display Service...
Apr 13 17:14:38 moode systemd[1]: Started OLED Display Service.
Apr 13 17:14:38 moode systemd[1]: oled.service: Main process exited, code=exited, status=1/FAILURE
Apr 13 17:14:38 moode systemd[1]: oled.service: Failed with result 'exit-code'.
Apr 13 17:14:38 moode systemd[1]: oled.service: Service RestartSec=100ms expired, scheduling restart.

what can I look at to fault find this error?
