For the last couple weeks, my 616 has been running OK. I can turn it on with the remote, as long as it's in standby mode, which I want anyway.
I updated the firmware to the 6/26 version, using the network option, and until tonight, had not an issue with the HDMI failing.
Since AMC and Dishnetwork can't get along, I recently ordered Verizon Fios TV. Last night, I set up the STB/DVR as another input on the 616, using for the first time the CBL/SAT input. It all seemed to work at the time...
Tonight, I get home from work, go to turn on the system to watch the news (on Dish) and NO F'ING HDMI. "Signal not found" or something like that, is on the TV.
Switching all the sources around, I can't get anything to show up. I take the HDMI cable coming from the satellite box, plug it straight into the TV, and it works.
Going through the menu (on the 616 display) looking to turn off the standby feature to see if that can change it. Can't find the option, but I do notice that CBL/SAT has a component video input turned ON, with all the others for component turned OFF. All of my sources are HDMI. Before last night, I had:
1. STB/DVR: Dishnetwork tuner/DVR
2. GAME: Boxee box
Both TV outputs used; a remote TV on the monitor output.
Last night I added the Fios STB/DVR to the mix, running HDMI into the CBL/SAT input.
So I turn that off, and I'm not sure the exact details that follow, but after turning that off, HDMI works again.
I tried turning that input back on (under the component inputs) to see if I could "break" the HDMI. It kept working.
Since I couldn't break it, I'm not sure it was really the cause, but thought I'd share this data point.
