VXOC Astra-J/GTC

Hi, we've got a problem with my daughters J (1.6 petrol)
started it today and the central info display between the speedo and rev counter doesn't light up
it looked like it trying to say the normal warnings, change oil, put foot on clutch etc all barely visible as not lit up in red

the last thing it said was PROGRAM CLUSTER

which doesn't sound good to me,

any ideas how I can cure this at home?

I've disconnected the battery and will try it again after an hour

OK then.
Update
reconnected battery and started up, everything seems to back to normal
Phew!!

You were quite lucky there then normally once program cluster appears it's goosed, but clearly just having a brain fart.
