Apple TV - Display Rolling / Scrolling

First thing to do is make sure yout TV is operational. i.e. If you plug other things (DVD, Xbox, etc..) into the same Component imputs on your TV, does it work properly?

If you get the same problems, then the issue is likely with your TV and I am sure Toshiba has a forum to get help.

If the TV works, as I am assuming it will, Make sure you have your Apple TV set to the correct Resolution. 1080i, 720p, etc.... AND that your TV can handle the resolution which you have chosen. also do not use the 50HZ options unless your TV is specifically able to support 50HZ.

Some TV's support 1080P while others only 1080i. 720P may or may not be supported... Pull your AppleTV all the way down to 480i, which is the most basic display setting, and slowly bring the resolutions up until you find one that works with your TV.

Hope that helps.... Also try a different set of cables or connecting AppleTV to a different TV. Isolate the problem by trying out different variations.

Ensure the cables are inserted correctly and firmly, if need be try another cable.

You need to establish where the problem arises. If you are sure it is not a cabling issue are you able to eliminate the tv or the tv by using either with another device.

Are you saying it now works?

ie:
You plugged it into a different monitor, got a stable screen, and changed the AppleTV output to 480i (or similar)?

It sounds as though you have connected your tv to a composite connection on your second tv. Since you have a stable picture on that tv, I would say your tv is working correctly (you will have connected the green out to yellow in and green out carries the component sync signal, so the tv seems to be generating its sync signal properly)

HDMI is intelligent, your tv will tell the tv which resolutions it supports and only display the options it can use. Component is not intelligent and hence your tv will display all of the outputs it has regardless of whether they are compatible with your tv or not.

I suppose it is possible to select the wrong option and obtain the rolling you are experiencing, however I would ordinarily expect a blank or blue screen on your tv and after a few seconds the tv would reset itself to a compatible resolution.

So could it be that:
Either your second tv is behaving as expected and your tv is setting itself to a compatible resolution or that simply your second tv supports both PAL and NTSC signals. Additionally could it also be that your first tv, although not compatible with the wrong type of signal is not actually rejecting it and hence the tv is not trying to reset its resolution. If this is the case and you are unable to see properly to alter your resolution because of rolling, then you could attach it to your second tv and set it from there. Given the information you have given I'm guessing the resolution you need is 480i/60 Hz.

Failing this you are likely looking at your connections again, but at least you know your tv is not defective.

good excuse to upgrade televisions

Mmmm, sounds like you've made your mind up, if you want we could start a new thread and convince your partner (if applicable) that a 60" 1080p tv is the only solution. ☺
