I had my replaced and they were glad to do it because they knew all about the bas HDMI port issue. I got a saavy gal at tech support, You have to get the tech support, customer service just can't help anyone.
My re[lacement 622 HDMI port failed within 2 weeks. Tech support told me to use the components ports and they work fine on my projector, however, I need to hook up my day time TV to HDMI, so its nack to tech support again!
