HELP! Promethean Board issue
We have a new Promethean 378pro board which continually drops the sound - the on button changes from green to red randomly. The board AND the cable have been changed with no improvement.
We have tried a laptop that is normally used with no issues on a different 378pro board of the same vintage and it doesn't work either. The teacher's laptop used normally with the failing board works fine with other boards.
As I said, the board has been changed and the techs who did it did see that there is still an issue, but could suggest nothing other than maybe it was because we use VLC player - which we do all over the school without an issue.
Can anyone offer ANY suggestions at all?
