Vauxhall Combo multi media center is blank

Could you maybe inadvertently switched it off ? Is there a on/ off switch ? A phone call to dealership should be all that's needed to help you . Maybe some settings can be adjusted when you get it working .

No. Was working fine when switched engine off last night. Then totally blank this morning. Definitely have not turned it off and yes I have tried turning it off and on again several times ??‍♀️

Only other thing I can think of is if low car battery , on some it cuts off certain non essential items till battery charge is up to scratch .
