LED light stays on blue but no display
The ActivPanel was working fine until my class had to leave it for circle time. Then the display looked garbled and frozen. I tried to turn off the ActivPanel but neither the remote or the button itself would turn it off. I reset the whole system, including laptop and turned the button off on the side of the monitor. After a few minutes, I turned everything back on and the ActivPanel LED has stayed blue but no display whatsoever of the "Activ Panel" screen or even the "no signal". Just nothing and it doesn't turn off. Please respond and help!
