      We have a Promethean board that will not turn on we have tried unplugging the power cord and leaving it unplugged for a while and trying a different remote and power cable and when we turn it on it makes a crackling noise!

      We are not sure what else to do, please could you offer any advice.


      Thank you

      Hi Vanessa,

      Thanks for your post.

      Is there any sign of the Panel receiving power when you try to turn on?

      Even a red LED/light showing the unit to be in “standby” at least?

      The crackling noise you mention, can you say where on the Panel this appears to be coming from?
