      Today my projector just started staying no signal. I’ve tried updating, disconnecting and reconnecting, unplugging everything, different computers, and made sure all wires were connected. I have a box mounted and it seems to not be working either. When I switch computer 1 and two buttons nothing shows up on the screen. The board itself works but I need the projector. Please help!! It’s a abv378pro. Updated to the most recent software!

      Hello Lindsey,

      Thank you for your post.

      Can you confirm the model of projector you have? You will find this on a white stick, on the projector.

      Are the cables from the computer connecting direct? If not, please test a direct connection.

      We look forward to hearing from you.

      Kind regards,
