How to Troubleshoot AVR Inputs Not Working

I just got a Denon AVR-S540BT receiver to replace an old and malfunctioning Onkyo TX-NR515. I have three devices connected to the HDMI inputs, a Roku streaming player, a MythTV (linux-based video recorder), and a computer output. The Roku signal displays fine.

For the MythTV input, when I switch to that it displays correctly for a split-second then disappears to a black screen. For the computer, it doesn't display at all, even briefly.

I'm not sure what HDMI version the latter two are using, but it's probably an older one. I assume the receiver is backward compatible. Can anyone give advice for troubleshooting the bad inputs?
