OLED screen still flickering after 5.service

Hi I have run sudo systemctl restart pironman5.service and oled screen still flickering. Is there a fix for this? When I first installed pironman5 module everything was working fine, I had to reflash the sd card and since then the screen has been playing up.I have transferred to ssd card but no change.
Thanks Clyde

It is recommended that you provide a video of the issue to help us analyze and resolve the problem.
What are the specifications of the power supply you are currently using?
It is suggested to use a 5V 5A power supply or the official Raspberry Pi 27W power supply.
What is the status of the indicator lights on the IO expansion board?
Is the green light constantly on?

Hi, False alarm! Don’t know what I did but all working good now after a reboot.

Thanks for your reply.
