No, but the micro HDMI sockets are fragile, especially if a heavy adapter is used to connect a full sized cable, instead of using a specific micro HDMI cable.
 It's probably why the machines were being sold off, but if you only intend to use one display, it shouldn't be a problem.

Both are working. What I didn't understand, about HDMI, was that the display need to be on before the Rpi. Rpi 'talks' to the display, whilst setting up, to enquire what the display resolutions it supports. If it doesn't get the replay, the Rpi doesn't activate the HDMI output - or at least that seems the way it is..
