Following a recent OTA (over the air) update something seems to have changed and myscreen won't stay on for more than 5 seconds before it goes back into sleep mode...

Screen -> Timeout ->
Select the period of time you wish for the screen to shut down. You may select never if no auto screen off is desired.
