Resposta para "HDMI stopped working on RCA tablet"Same problem, no solution for several weeks until: Then, by chance it started working. Reason: the connector to the tablet is semi-defective, and it just happened to be in the right place at the right time -- for a few minutes. After some jockeying around, got it to work again. (It's not the cable since it works well in another connection.) Seeing the micro card connection behind, I wondered: plugging in a card helps stabilize the connection. So, at least in this case, it is a defective, poorly built tablet, but beyond the return date. I am worried about the stability of the connection and what to do if it fails completely.
