I will have to wait until morning to check the TV model. Its kinda big and I cant get behind it alone.
I can not attach the manual or submit direct links do to low post cound. But here is a link to where you can find it: w w w.retrevo.com/pdf/23411dj088/6/AV+receiver+HT-R370/]Onkyo HT-R370 manual (You can look through it without DLing it too)
The out putting 24p or 60p I dont know what that is. Since I doubt I touched it, I'm not going to worry.
Thanks for the help and inputs so far guys.
I read the manual, but it does not talk about how to select HDMI inputs so I assume you are right about not having to assign them. It may just pass through anything from any of the 3 inputs and assume that you (like most people) would only turn on one source at a time.
Anyway, I suggest you check the following:
1. Correct input on TV - Make sure the TV is selected to the correct input, e.g. it may have more than one HDMI input so you have to select it to the one connected to the HT-R370's output.
2. Inputs on AVR - Try connecting the BD player's output to each of the 3 HDMI inputs of the HT-R370.
3. HDMI output resolution - You have a very nice BD player but your TV is a few years old so it may not take 1080p/60, let along 24p that Josten already covered. If you have not touched the BD player's settings it may default to 1080p, I would think that they typically default to auto but I am not sure. Even if it defaults to 'auto', try setting it to the lowest resolution and go from there. That is, try 480i first, then 480p, 720p, then 1080i, and see if the TV would do anything for you.
4. Cable - If everything checks out, try a different HDMI cable.
5. Equipment Defects or potential HDCP issues - If nothing works, contact Onkyo and/or Sony tech support.
