I have noticed that my 5000T often switches from red to blue with no obvious reason, like a press of any of the buttons (box or remote). The only time it is supposed to come on without a recording taking place is for a power timer session at 0700.
I am not sure if it might be responding in some way to my Topfield 5800 remote, but I have not been able to find a button which does it (I tried pressing every button, one-by-one), nor have I actually seen the moment of it coming on to know what I had just done.
Has anyone seen any similar behaviour with, or without, a different remote being in use?
