Double Picture on my VU+ Solo

[acertech]

Hello all!
In the last days I have had some problems with my VU+ Solo. I use the latest image for my VU+ Solo. When I switch channel the last channel lies upon the channel I choose as for if I am on Discovery and then goes to History Channel Discovery lies as a picture over the History Channel picture. All channels are the same. Hope some have a solution on that.
Best wishes from Norway.
