Hi folks,
Got one in where at plug in, Samsung graphic shows on the screen, then HDMI 3 appears in the top corner - Set then cuts to S/by, then Graphic and HDMI 3 again, then repeats continuously.
Neither RCU nor set controls have any effect. First thought it could be Sammy tact switches but it doesn't have any, being touch control on the lower front panel.
Any thoughts ? - Thanks - Chris.
