Sound but no pic (get menus fine)

[birdman]

My Xtrend et8000 has a similar issue.

From time to time it will start up with no picture. Usually putting it into standby, waiting a few seconds and taking it out of standby restores the picture (which at least means recordings continue OK).

My suspicion is that it's something to do with HDMI-CEC, as trying to use ARC for the sound doesn't work properly with this system connected along with an MBTwin (so I now use an optical cable instead).
