Have been using full graphics smart controller for some time. Ended up giving it a shock. Now only blue screen. Ordered new one. It powers up. Says No SD inserted. When I connect via USB, it recognizes the card and loads the file. If I connect my 12v lower supply and USB it works. However, with only the power supply connected, it says No SD insnerted. Any guesses?
Meantime, I have ordered a new controller
