I just bouht a mini-10 - when the hdmi cable is plugged in it just keeps turning the screen off and on. It was sent back to dell, dell sent it back "fixed" it worked for netflix for about a day (connected to a 32 didgetal TV).
The next time I tried to use it, it again started turning the screen off and on again and it would not output to the didgetal tv again.
The mini 10 is only used for i-tunes, internet, sirius radio and didgetal tv via netflix.
I had dell support on for an hour, and they send send it back for repair (which I did) - I think there is a software conflict somewhere, I just don't know where.
Anyone have any ideas?
