Hi Tony,
    I did not see anything unusual on the screen before this happened, however
tonight I will look closer and let you know..
I am planning on disconnecting the power sullpy from the rest of the components
and see what happens if I power it up alone..
I will look very close at the yoke assemble also..

Thanks for your interest.. Very kind of you..
Back to you later...
