    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

    I had some very similar issues when using a 3′ cable for the controller, the SD card sometimes would not work. I changed to a 2′ cable and the problems went away.

    Thank you for your reply, Hubert. I have read that long cables cause problems. Mine are onlky about 6″ long. Going to buy a new SSD card. Fingers crossed
