I have a TiVo Series 3 HD DVR connected to the digital input composite terminals - Video Input 5 of the Sony KP-53HS10. Previously I had a Scientific Atlanta HD set top cable box connected to the same Video 5 input terminal. My problem is that during HD broadcasts from either of the above sources the screen goes black whenever there is a sudden change to the video such as a fast action scene or dark to light such as a gun or lightning flash. It also occurs if there is a very light background at the top of the screen. The Sony TV input signal detection circuitry resets for some unknown reason and thus the black screen. When the picture reappears the TV displays the input it is using (video 5) and the type of signal it is receiving (e.g 1080i.) I believe this occurs because the composite input circuitry of Video Input 5 automatically detects whether the signal is 480 (normal or letterbox), 720 or 1080i and then automatically adjusts the screen aspect size accordingly. Is there was a way to manually set the input to 1080i so that this reset of the video phenomenon would not occur? Is my diagnosis correct and is there a solution. I am at the point of purchasing a new HD TV since the problem is very annoying.
I just posted this to another Sony owner:
Another point; HD Ready does not mean that it is HD compatible without the addition of an optional part.
The title only implies that it can be adapted to HD reception.
If you did not purchase it with the set, check your user guide to see what you need to make it whole.
You may have to seek this add-on on eBay since it is not guaranteed that Sony will still offer it.

Have you already tried to power cycle all the devices? Unplug the power cable on all your devices for about 1 hour then plug it back in. Check if that fixes it.

This is an HD TV with appropriate digital input jacks (red, green & blue cables) so that an HD output cable box or HD output DVR such as the TiVo Series 3 unit can connect to it and the set will then detect and display either 720 or 1080i high definition shows. It doesn't have an HD over-the-air (OTA) tuner so it can not be used after the conversion to digital broadcast in Feb. 2009 without a converter box.
This is all unrelated to my problem.
I am having the same issue. Did you ever find a resolution?
Thanks.
