Thanks. I have updated the firmware, Rigol was very quick at getting that to me, still no difference. And yes, I have tried the second channel also.
Ok, good know the -S shouldn't be there....so yes, it is now looking like a hardware related issue.
I wonder how it switches to output mode, as it stays in input mode no matter what I do, even thought the Source light is on an the software tells me that output is on.
It does have a seal for warrenty, so i am not going to open my self in case it is something more serious. Looks like I need to talk to the people I got the scope from.
