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
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
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.

Re: Screen goes black and resets during HD shows
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.

According to the owner's manual page 2.7 (and this is an OLD [by HDTV standards] set), the TV can only handle input resolutions of 480p or 1080i on the composite inputs. Most HDTV programming today is 720p with some 1080i and 1080p on certain channels (like some Discovery shows about nature). It is possible that your set will not process the 720p signals being sent.
The output from the blu-ray is probably component video, where the brightness, blue and red difference signals are the three outputs. Sounds like the TV only has composite video input so won't work. Check the manuals, if you can get a composite signal from the blu-ray then your TV will display it but not high definition. A HD LCD or plasma TV is needed to show the blu-ray films in high definition.
There could be several things that can cause this:
1. There are no analog channels in your area.
2. Check the menu setup and verify that you select the proper input (antenna, cable, etc).
3. The TV tuner is defective
Try using the composite input on the TV (there are normally 3 jacks per input). Yellow for video and red and black for audio. If you dont have the proper cable, pick one up in you local 99 cent store or an electronic store.
Connect the "output" of your device (VCR, cable box, Tivo, dvd player, etc) to the "input" on the TV. Then use your TV remote to select the proper input.
Hopefully this helps. Good luck.
The ProScan will accept input on input 90/91/92 using the connectors on the backside. You can use S-video[the little round black connector] or the composite video [yellow connector] for the video in and use the red / white pair for audio in. 90 selects S-video and audio 1 in 91 selects composite and audio 1 in 92 selects composite in 2 and audio 2 in Connect these cords to the S-video or composite yellow output, and the Red-right White- left audio outputs on the DVD. If you don't want to do this, get a RF modulator ~$15, and connect the yellow/red/white from the DVD output to the inputs on the modulator, and then connect the RF [cable] output of the modulator to the antenna input on the ProScan, and tune channel 3 or 4. tom
Are you on Cable service or Direct TV. Have you tried the analog signal? HDTV ready monitor can use a standard analog signal. Most HDTV ready
tv's have analog tuners built into them, meaning you can use standard
cable/over the air signals on them. They will not be high definition.
You can use the analog hookup by hooking it to the coaxial antenna
hookup, or, if you have a cable box, it may have a set of audio/video
outs (the red-white-yellow rca plugs on the back) that you can use to
hook up for a slightly sharper picture.
Does the problem still persist without the Tivo connected? Try to isolate each devices that are plugged in. Try to watch a normal dvd first without the Tvio connected and see if the same problem occurs.
if you are connecting the dvr via component video cables select the output to 480i and not 480p or other higher formats.the tv cannot support anything higher than 480i. or try using composite video hookup instead.
