Recently installed a Sharp Aquos with Hdmi to cable box (explorer8300). Worked for a day then this message appeared. "Your hdtv does not support hdmi, use yprpb conns. Now I know what this means but why is this . Anyone ever seen this? The tv is advertised as 1080i. Can I even get 1080i out of component wiring or is 720 the best. I reset all and its working again but how long will it last. Just incase it stops working I'm using the component wiring that is there for the dvd player to be on another video input so the customer can switch inputs. By the way what a difference in pic quality from component to hdmi. I'm still new at this stuff so any help would be great.

Component supports 1080i. You won't see any difference in picture quality.

As an interesting sidenote, when I'm connected via component and I try to watch a PPV movie on DirecTV, I get a message that says I cannot watch it via HDMI (keep in mind that I'm connected via component), and that I must switch to component in order to watch my movie. I switch to HDMI and watch the movie, no problem.

sounds like a handshake problem w/ HDCP between the two devices.

"High-bandwidth Digital Content Protection (HDCP)". A chip in the player and a chip in the display have to agree with each other that they have compatible licenses to send HD content across the connection between themselves.

Welcome to the insane world of Digital Rights Management.

If drivers licenses had DRM, I could have a license to drive in Minnesota, but it may be illegal for me to drive in Wisconsin and yet I can drive in Michigan.
 
I hope we are all talking the same language?

Component is using 5 RGB+left and right audio cables, and are RCA type ends, composite is one (yellow) RCA and the two left and right audio cables, if the latter you will get no HD, but I have had no problem with 1080i HD with the component.

as far as the HDMI goes I would have the home owner contact the cable company as it could be a problem with the box?

Any idea why I'm seeing such a big difference?

could be the output settings for the component jacks, if the device has such. maybe your component output is set to 480i?

or it could be a setting for that input on the tv itself.

you should see zero difference in picture quality between component and hdmi.

could be a problem w/ the cable itself.

analog component in the US is mostly YPbPr for consumer grade equipment.

1080i is 1080i, regardless of whether it is component, HDMI, or DVI.

As was suggested earlier, make sure the settings on your YPbPr outputs are 1080i, as are the inputs on your TV set or monitor. Gotta have high quality jumper cables as well.

And component is also an analog medium. Some people say that when component cabling is used and displayed on an analog device (CRT), the coloring can be a little better than with a digital medium and display because the number of color possibilities is not limited by a finite number of 1s and 0s.

well sorta component is a analog signal. hdmi and DVI are both digital.
DVI does not have audio and HDCP.
There is a difference. Can most people spot the difference probably not. However they are not the same.

Not to disagree with "egnlsn" who is an expert on things TV and cable.
Just a few thoughts on possible differences in picture quality:
a) Different devices be they STB's, receivers or TV's sometimes have a mind of their own on how to handle any signal.
b) Some TV's have a native resolution that is different than the standard output resolutions. In this case it may be best to let the TV convert the resolution.
c) Each TV input has adjustments for things like color, contrast and brightness. Different inputs may have different adjustments available. Some of your inputs may be way different than other inputs.
d) Still if the pictures are wildly different, something is not setup correctly.

Component, HDMI, and DVI are delivery systems. Of course, there are differences between delivery systems. The information transported, though, is the same, regardless of the delivery system.

Just like you send three identical packages to the same location via UPS, FedEx, and the USPS. They all get to their destination and the contents of each are just as identical as when they were shipped. The only difference was how they got there.

This real world analogy demonstrates the issue quite well - the packages may all have started out the same, but one courier consistantly damages goods in transit, and what is delievered is different to what is sent.

I think we've all experienced this one :)

Does this issue tend to happen when the TV is turned on first and the cable box is turned on afterward?
I ran into a similar issue with a TV I had installed (Samsung) where we would get an error message when the TV was turned on before the cable box. It did have something to do with a "handshake" when using the HDMI medium. We just ended up making sure the cable box was the first device turned on. I do not know HDMI stuff like some of the other people who have responded but this was the issue when we were having problems @ a customer's site.
