Not with my Kemper, mine is fine.
A client of mine and his Kemper.
The screen keeps going blank, it stays lit, but it's blank with nothing on it, and all the lights of the unit go off as well.
When he turns if off the screen stays lit but doesn't turn off.
So, he unplugged the power cable, that obviously turns it off.
Then whilst holding down the RIG button he turned it on.
It switched on like normal.
He thought perhaps restoring the "Factory Rigs" might sort things out, but before he could do that the screen goes blank again and we're back to square one.
Any advice?
