Hello,

I have managed to turn on my 48S by using the on + pressing between the screen and the B key.
After that I have done the memory reset and I got to the home screen but sadly it seems like it is not accepting the input.
Any ideas / fixes?

Thanks!

Have you tried pressing between the screen and top row of keys while trying to press any of the keys? Often the On key isn’t the only key that doesn’t work because of the dreaded “keyboard issue”.

Hello - yes and it randomly responds to inputs. I totally forgot what you are meant to do when on the home screen you are prompted to choose the different modes.
