Hi, as you suspected, I think it was a bad cable.

I started by testing the a provided EDID (using the drm_kms_helper trick). It
worked by I saw strange things :
- the device name was replaced by '@@@' (in the XBMC screen)
- the audio capabilities reported only PCM and AC3 (and was missing AC3+, DTS,
and others)

so I reverted back this change.

Then I exchanged the cable (2 days ago). Just touching the cable head was
producting either black screen or graphics corruption (a lot of "colored
snow").

Since I exchanged the cable, I did not see the black screen again (during 2
evenings).

Strangely, I also tested the bad cable a few minutes in another set of
equipment (another TV and another device) and I didn't saw any problems, even
when trying to move/bend the cable. Anyway, I'll stay in this setup.

So I guess you can change the status to resolved/notabug ?

I thank you again for your time.
Best regards !
