I can only assume that my HDMI port is toast, but I wanted to try to post here before figuring out what to do next.

TV: Sony KDF-55WF655
Source: DirecTV HR10-250

This just happened all of a sudden, today. I tried hooking up 2 different HD Tivo's, with 2 different HDMI cables, and rebooted/power cycled everything involved (both sources and the TV), and nothing changes. Both sources look fine using either component or S-video, but neither works at all with HDMI. The picture is very, very dim, mostly red and blue tints, not normal color at all, and is constantly scrolling sideways. Here's the best picture I could get of it.

So, is my HDMI port on the TV dead? Thanks in advance.

So, it started working again... which means I guess I just wait to see how long it lasts.

About 12 hours, that's how long it lasted before going out again. Ok, time to find my paperwork to see if this puppy's still under warranty, I guess.
