I am just wondering about this as there are at least 2 of us so far whose Primes have stopped playing HDMI to TV as it appears that the HDMI port has loosened up from the motherboard! When I first got my Prime it worked great but right after the ICS update it stopped working but it did work a time or two after updating.
There are several HDMI issues people are having from no video to no audio to no nothing! Anyway, please take a minute to do the poll and leave a comment about your experience. Also interesting to note is do you use the HDMI often such as 4 times or more a week or occasionally 1-2 times a week. I am sending my unit off to have the HDMI port repaired and I hope this will be a 1 time fix! I plug the HDMI cord in almost daily and it should hold up to that kind of use!
