Default Help: TV won't pick up HDMI connection

Trying to help the BF make less of a mess of his current set-up and what should be working won't. Feel like I know my way around something this basic, but am hoping someone might be able to give me some info why this might not be working.

Components:
Samsung LN52A650A1f
Cable box - Explorer8300HD
Panasonic DVD Home Theater Sound System - SC-PT770

What we tried:
1 HDMI to cable box and another to DVD player w/ fiber optic for audio.

What's not working: TV refuses to pick up cable through HDMI. When we take it out and replace it with component video cables everything is OK.

THOUGHTS? Many thanks in advance.

Connect cable box to home theater system then to TV via HDMI cable.

There is only one HDMI on the home theater system, so what do you suggest using to connec the cable box to the home theater system. Thanks a bunch. I am determined to figure this out.

I'd connect the 8300 s/pdif output to the Panny s/pdif input for audio. For video I'd connect the Panny to the TV via HDMI, and the same for the 8300. If you have trouble getting video over HDMI, try a different HDMI input on the TV. If that doesn't work, try another HDMI cable. If that still doesn't work, contact your cable company - there might be something wrong with your 8300.

I have an 8300 and I didn't have to do anything in order to get video (and audio) over HDMI.

There might be a resolution mismatch between the cable box and the TV. The cable box output resolution and TV input resolution need to match, although that is usually handled by the HDMI handshake. Or, maybe you need to enable the HDMI output on the cable box. The rest of your set-up looks fine.

Two quick follow-up questions.

1 - How can I tell what the TV input resolution is? I already know how to change the output on the cable box.
2 - Any idea how to enable the HDMI output on the cable box? I was literally joking about an "ON" switch earlier.

Sorry if these are basic questions, but I guess I was banking on an easy handshake.

Sorry, but I am not familiar with the settings on your TV or cable box. The manuals should have that information.

Your TV appears to be a 1080p TV. The TV should accept any resolution, including the 1080i from the cable box.

The cable box should have the HDMI port automatically live/enabled.

What is needed to connect an older Sony with bnc RGB inputs and pin RGB inputs to a new Sony Blue Ray player with HDMI outputs? Do I need a converter? What is that converter called? Thanks.
