Anyone else found themselves thinking they had forgotten to switch their TV off? Or that it had mysteriously switched itself on?
Well I did this morning, and it turns out it's down to a new software version that Sky kindly downloaded to my Sky box overnight. This version has a new feature that allows the Sky box to actually turn on a TV that's in standby if it's attached to the HDMI port when you press the Sky button on the remote. This new feature is turned on by default.
And what does my TiVo do when it wants to record something? It sends the Sky button code followed by the channel it wants. So at some point last night, my Sky box got updated, some time later my TiVo went to record something, sent the Sky button code and the Sky box promptly turned on the TV... which then stayed on until I went into the living room at lunch time.
Luckily (for once) Sky has been thoughtful enough to include a menu option to turn off this HDMI control, which I've now done.
Updates will be the death of me I'm sure...
