HDMI Won't Work for me...

I'm a newbie with a 37" LG LCD (37lc2d).

It works fine on regular cables, but when I try an HDMI cable I get no picture or sound.

The unit has only a single HDMI receptor.

I've used the same HDMI cable on my other TV.

What might be causing this? I can't find any mention of an "HDMI switch" or something that needs to be on before I can use HDMI.

Sorry if this is a silly question, but I sure can't figure out what to try.

Thanks much for any help!

Hi BCF and thanks for responding.

The HDMI cable goes from the cable box to the TV. There are no other devices, just the cable box and the TV.

Do I need to try the remote's Input button anyway? I've never used the Input button before with the other cables?


Thanks again,


Alan

Thanks, BCF, that did the trick!

Can't believe I hadn't even considered it.

I like how we can switch (via Input) between HDMI and the original connection.

I found it interesting that the HDMI quality on the LG isn't noticeably better than what we had before. I guess my expectations were a bit too high because I was comparing it to our 55" plasma.

Thank you again,

Hi Greg,

Yes, the channels we watch are HD.

The cable box is a Cisco 8640HD (Time-Warner).

On the same channels, the picture actually looks very slightly larger with the old non-HD cables. Not sure why....


Thanks,


Alan

Thanks Greg, that did the trick!

I never knew the cable box had a setting - mine had been set to 480i and when I increased it to 1180 (or whatever that number is) it really made a difference.


Thanks again!
