Ok here goes, I just lost a second 622 to a failed HDMI port. My first 622 (Installed Dec 06) went out after the power flashed off for a minute or two (I get frequent, short power interruptions here). The failure was different than what others have posted, I would get a picture and audio, but the picture and sound would blink off for about half a second every 2-3 seconds. Last week I replaced that with a brand new 622, fresh from the factory, this one even said HDMI on the back instead of digital video out.
Fast forward to today, the power went out again for a couple minutes, and when it came back on I had the same exact problem with the HDMI port! All other outputs work, except the HDMI port blinks on and off again! I tried unplugging the tv and 622, and I continue to have the same problem.
I know, I know, I should of had it on a UPS! I am going to pick one up now! Can anyone recommend a reasonably priced UPS for my 622 and JVC D-ILA? I was going to get one to protect the bulb on the tv but never got around to it...shame on me. Anyone have any other ideas?
