Infotainment not switching on

[PeterBOcean2017]

I found my battery had discharged recently. Now charged up and vehicle starting normally but the infotainment will not switch on. Any advice please.

Problem sorted, press the on/off button for about 10 secs. Now working normally.

My infotainment system is draining battery when on standby. Any suggestions?

Can you provide more detail please.

Are you sure it is the infotainment system? How have you reached this conclusion?
Is this when you leave the van locked up?
Any other systems fitted to the van like a tracker, permanently live dashcam, third party alarm system, etc?

What rate of battery drain are you seeing?
