I have a lenovo Yoga w/ windows 8. I've been linking this to a sinotec spj-86c projector, with an HDMI 1.5 meter cable, and a mini hdmi piece to connect to my laptop (as it doesn't have the normal size hdmi).

This has been working fine for 6 months, until recently the projector screen says "invalid for..."

I have tried a new hdmi cable (not the adaptor though) and have tried to fit the display resolution of the laptop to the projector. None of this works. I've even restored factory settings on the projector.

To be honest this problem began after putting this projector in a car (wrapped in a duvet), on an hour long drive. Could I have damaged something inside that is causing this?

Thanks
