Problems with ATV displaying on various HD TVs

I have 3 HD TVs in the house, 1 with HDMI input and the other 2 with DVI inputs. On the 2 TVs with DVI inputs, the ATV displays fine using a HDMI to DVI cable, but will not display using a component cable into the component input. On the 3rd TV it will not display on neither the HDMI input nor the component input. I keep getting an error displayed by the TVs stating the signal cannot be displayed.

When I connect my HD cable box (1080i) on all TVs, there is no problems at all with seeing the programming.

So, why is the ATV unable to display via component on all 3 sets, and via HDMI on the one set..??

Are you connecting more than one display at once?

Could be either a loading issue or the resolution is not compatible with one or more of the sets.

When it says the signal cannot be displayed it indicates the resolution is beyond the spec of the set you're running it through.

I'm not sure what you mean by more than one display at once. I am not using an input switcher if that is what you are referring to.

The resolution for the ATV shouldn't be any different than the resolution for the cable box when connected. The cable box displays fine at 1080i. I can't even display the ATV to determine the setting. But, what you mention also triggers something else interesting to mention. When connected to the DVI input (successfully), the ATV provides a different list of available resolutions for each TV. For one TV, the ATV shows 720p and 480p available. When connected to the other TV, the ATV shows 480p, 576p, 720p, and 1080i as available.

It would seem like your AppleTV isn't detecting available connections/resolutions with those TVs.

What are the make and model of each TV? I'm not saying there may not be a problem with the AppleTV, I'd just like to rule out your current TVs first since it seems the AppleTV is detecting what resolutions are available and for others no singal is transmitted.

I'm also assuming that you unplugging, moving, and plugging in the AppleTV to power after making the TV connection and not leaving it on and bringing the TVs to the AppleTV as well as connecting two TVs to the AppleTV at once trying to use both the component output and HDMI output at the same time.

Thanks for responding. Here are the TVs and how they work with the ATV:

Samsung HLN617W - Works only thru the DVI input. Does not work thru component.
Phillips 23PF5320/28 - Works only thru the DVI input. Does not work thru component.
Olevia 232-S13 - Does not work thru HDMI nor component.

Yes, I have been unplugging the ATV each time to let it reset. No, I am not using HDMI & component out of the ATV at the same time.

This makes absolutely no sense to me. Not your post, just what the problem is.

Yeah, assuming all things constant and nothing else being wrong. I would exchange the AppleTV and see if the problem persists.

I say this, even though HDMI > DVI works except the instance of HDMI > HDMI because the component doesn't work at all.

It doesn't make sense that component doesn't work at all on any TV unless it's the cables - I also doubt this.

I'm sorry I'm not more help, but it sounds like maybe one of the interfaces in the AppleTV may not be working properly. It happens, I guess. I could also be totally wrong, that happens too.

This seems like the most logical next step.

When you connect via HDMI it should only display the video modes which the tv outputs that are also accepted by the tv as inputs, when you connect by component the tv can't detect what inputs the tv uses and therefor offers all it has. It's possible that over some DVI ports HDMI is not able to detect the inputs the tv accepts.

If your video mode is set to an output that the tv doesn't accept over component, it may take a while but it should begin to cycle through them, if not try holding down the menu and the scroll up buttons down simultaneously on the remote for 10 seconds or so to force it to cycle through them.

It's really very strange that 3 tv's don't work over component, component while being the poorer brother quality wise is usually rock steady connection wise compared to HDMI, I feel there is something being overlooked here or you have 3 bad tv's or 3 bad sets of cables or 3 bad component ports on the tv's, any of which I'd find hard to accept.

They are definitely component connectors on the tv's are they, they are not composite, RGB, Y'Cb'Cr or professional connectors are they.

I've got the exact same problem with my Olevia TV. Though the problem only started after I upgraded to the latest version of Apple TV. I've replaced cables switched ports that I know work fine with things like my Xbox and PS3. I have to pull the power and reboot my Apple TV everytime I want to use it. If I switch input back to Tuner or something else and come back my Apple TV may flash up for about a second and then I am sitting at No Signal! screen. So frustrating. Anyone have any insight?
