Troubleshooting LCD screen

[ahmedess]

Sometimes when i press the push button on the controller i get a blank screen instead of the main display screen and it stays like that until i unplug the controller from power and replug it back in

[rimai]

Do you have custom main screen?

[ahmedess]

Yes. It also flikers when its blank like that

[rimai]

Can I see the code?

I don't see anything wrong except for the Portal() function, which should be just above ReefAngel.ShowInterface();

[ahmedess]

It doesnt happen all the time but its been happening more often lately

[rimai]

Was there anything added lately? Equipment change or anything?

[ahmedess]

No

[ahmedess]

It also stays lit for longer than the specified LCD timeout

[rimai]

I can't replicate the problem.
What happens if you remove the jumpers from the head unit?
This will disable your expansion modules, though.

I uploaded the code again to the controller after fixing the code as you mentioned and i ll test and see
