The unit stopped while playing an avi video from USB, as if the file was corrupted (which was not). Then menus seemed messed up (language changed, some settings changed) and "demo mode" was spontaneously enabled, with half screen ("XD on") black and half screen ("XD off") apparently OK. I couldn't disable it, as the menus were not behaving properly. There was also no audio output.
I did a factory reset (from Options menu) and after the reboot the audio came back, with menus working normally. The Demo mode, still active, was now showing in the left "XD on" half the expected image (no more full black as before) but the colours were wrong, looking as if some blue, semitransparent veil, had been put on top of the screen. In the right half ("XD off"), however, colours looked normal.
When I disabled Demo mode the right half disappeared (as expected, actually) and so now I have a whole "blueish" screen, which obviously makes the unit unusable, as long as I don't settle for staring just at menus and teletext, which still appear in their right colours, as if they were on top of the "veil".
I thought I could maybe try some "hard reset" or, at least, try to disable that "XD" algorithm (so that the right part of the Demo screen could gain priority).
I tried those "service menus" reachable with the standard remote, but I didn't find any apparently useful options.
Before throwing the unit away I'd like to understand what happened and also to be sure that the problem is not easily solvable, for example just a software one.
Thanks in advance for any advice or suggestion.
