      Hi!

      A teacher has a AP7-U65 nickel panel.

      Recently, when she presses the power button on the promethean board, the button turns white, and the purple background flashes on the screen for a second but then turns completely black. Can’t use any of the buttons to change source and trying to connect a laptop through HDMI doesn’t do anything.

      We tried unplugging, turning off the power switch, but still no results. Any ideas?

      Hi Lisa,

      Thanks for posting.

      When the screen turns completely black after showing the background flash, what colour is the Power LED at the point?

      If this is still lit white and no image is displayed i’d recommend getting in touch with Promethean Technical Support directly and providing your hardware serial number to them.

      Kind regard,s

      Adam

      Hi Adam,

      Yes the power LED flame remains white and the screen is completely dark/off. Thank you for the input, I have reached out to customer support.
