There are 2 possible causes the HDMI wouldn't work:
1 - the resolution is et too high - the tv can't display FullHD images (also known as 1080p) so you must check in the settings of the receiver that the output resolution is set to 720p or 1080i.
2 - the HDMI jack itself has failed - check that by plugging something else in it.
