My Relay G70 Model RS516 suddenly stop working after I have plugged a bass guitar with into Aux In with a cable just to use the external tuner I have connect on my guitar pedalboard. Really weird as so far as I know should work fine with both, guitar and bass. Anyway, the problem is that now the switch color ring and the audio led are blinking red and there is no sound at all either wireless or cable plugged into the Aux In. Also the LCD backlight display has gone, no light at all but text is still there, I can switch between the transmitters-scenes I have, I can see the battery information and so one, but NO SOUND and NO LCD Backlight.
Is this a known issues? There is something I can do by myself or it requires a service?
