HDMI doesn't work on a tv

  • Hello

    I have a Rasberry with Librelec. It's work on my tv sony. It doesnt work on my tv Philips. I have just the first picture red-blue then a black screen and th'as all.

    What could it be ?

    Edit:

    OK

    I found the matter. I was on HDMI's port number 2 and it doesn't worked. It's ok on port number 1.

    You can close this case.
