Scientific atlanta cable box hdmi not working
I have recently purchased a Pioneer Elite 1150 50" Plasma and I am having great difficulty in getting the HDMI to work. I currently have a Cox Communications(Scientific Atlanta)8240 DVR. I have the HDMI cable going from the cable box to the T.V. and have no video what so ever. The audio is run thru RCA cables into a tuner that does not have HDMI, that works fine.
The cable box has been swapped out twice with no luck in fixing the problem. I've tried an HDMI DVD player and tested all the HDMI ports on the TV and they all worked fine. I've also tried different HDMI cables to no avail.
The cable company doesn't know what to think as do I.
Any help would be appreciated in solving this.
I've also been told Cox runs HDMI 1.0 and the T.V. is 1.3 which might cause a problem, but I'm not entirely sold on that.
I am running the component cables and they work fine, great picture.
My cable box is a scientific atlanta box. I have timewarner cable.
When they hooked everything up they used the Component RGB cable from the cable box to the tv and the red/white rca calbe to the tv for sound.
I just get no signal when I switch to one of the lower channels on the cable box that aren't HD.

After searching around google I found a few things about it. I might have run a setup wizard on the cable box. It sounds like its only outputting 1080i through hdmi and not the 480 stuff
My only options are Automatic, 480i, 480p, 720p and 1080i
If i put it on automatic and I move to a non HD channel, my cable box keeps switching the signal from 480 to 1080 back an forth.
If i manually set it to 480 I can then view the station.
I just think the cable box is buggy.
I am just leaving the RGB on it. It does 1080i through that cable just fine.
