I've been enjoying my 2310CI for a number of years now and have been more than a little satisfied with it truth tell. Kudos to AVS Forum for being instrumental in its selection.
That was easy. When I cleaned it I went for minimally invasive and didn't actually pull the main board completely out. After my initial post I figured I couldn't make it any *less* functional so I ripped everything out, and it turns out some of the battery goo had crawled up along the side of the remote and was shorting the HDMI Control and Return buttons so they were "always pressed". More thorough cleaning and *ding*, good as new.
So it appears four flashes from the remote means "key stuck".
Today I tried to switch sources and it wouldn't do anything. It's been a coon's age since I put batteries in it, so I popped open the cover to replace them. /o\ Battery goo everywhere! I normally use the satellite remote for basic functions so it's been a while since I even touched this remote, but a quick examination revealed it must have been recent because little corrosion was in evidence.
Being a hobbyist electronics guy I popped it apart, washed it, let it dry for a goodly amount of time, and put it back together. I was of course very careful not to actually get the circuit board wet; the main purpose for the washing was to thoroughly clean the bottom part of the unit where the battery connections are to ensure no battery acid remained to cause problems later.
I put batteries in and now the power LED flashes four times times, pauses, flashes four times. The manual says nothing, searching this forum says nothing, and so far searching the web shows nothing. I'm thinking nothing is really damaged, it's just looking for some particular condition that I can't discover.
If it is toast, well, I've been wanting a Harmony all these years. Maybe it's high time to get one.
Thanks for your time...
