      I have a teacher with an AP4-70 and the screen will dim and brighten every few seconds repeatedly for no apparent reason.  While dim, the image is viewable — it’s just an annoyance to have the brightness flip back and forth.  I’ve plugged the power into another outlet to bypass a power strip but it does the same thing.  I’m wondering if this could be resolved by a firmware update or if it sounds like a larger issue?

      Thank you for your assistance.
