Number In Spx-display Is Dotted, Pfl-led Is Always Blinking.
There is a problem on my MG12XU. The PFL-LED is always blinking, even if no PFL-button is pressed and therefore no signal level of the output is shown. But when a PFL-button is pressed you can see the signal level of the corresponding input. Also the program number on the SPX-display is dotted. (For example 12. is shown instead of 12). Is this probably a single problem of the SPX?
