WARNING - Digital Back has no power

[BenScottphotography]

Hey Guys,  i just turned on my H4D-40 and i am getting this warning  "Digital Back has no power",  anyone come across this before?

Hi Ben
Sometimes the start up sequence gets a bit mangled and either the body or the back *only* will boot up. Just cycle the power or drop the battery off. If it keeps occurring check contactss between back and body.
Cheers
