A teacher’s flat panel was being used simply as a touch screen. After 3 weeks of basic usage, the screen now stays frozen on what looks like a sym card icon with a line through it. I have no idea what that means. The computer works fine and is still connected to the board. But this red icon stays on the board’s screen and is frozen. I have tried going to all categories on the menu to fix it. To no avail. What is my next step? Keep in mind, I have already unplugged everything, shut down and booted everything back up. Now what?
Thanks for posting on the Support Community.
Please can you let us know what model of ActivPanel you are using?
Please can you also provide a photo of what you see on the displayed screen?
