Re: television display

In basic terms TV images are made up of hundreds of horizontal lines, with interlaced scan it will display in order line 1, 3, 5, 7 and so on and once it reaches the end it will fill in the missing lines 2, 4, 6 and so on until it starts again.
For progressive scan it will display the lines in order 1, 2, 3, 4, 5 etc.

Progressive scan?

No it's interlaced..
Progressive or noninterlaced scanning is a method for displaying, storing or transmitting moving images in which all the lines of each frame are drawn in sequence. This is in contrast to the interlacing used in traditional television systems where only the odd lines, then the even lines of each frame (each image now called a field) are drawn alternately.
The system was originally known as "sequential scanning" when it was used in the Baird 240 line television transmissions from Alexandra Palace, England in 1936. It was also used in Baird's experimental transmissions using 30 lines in the 1920s.

Hi - Here is a description of a few terms that might help, especially if you're in the market for a tv. If this answers your question PLEASE rate this as fixed. If you need more help just add a comment and I'll be glad to assist you further. Thanks.

High definition television is the highest form of digital television. It has a 16:9 aspect ratio, which is the same as a movie theater screen. This is possibly HD’s biggest selling point. The other is the resolution. High definition is the best available picture on a television. It comes in three different flavors: 720p, 1080i and 1080p.
What do 720p, 1080i and 1080p mean?
High definition programs are encoded with a type of resolution: 720p, 1080i or 1080p. The number stands for the amount of lines embedded within the signal. The letter describes the type of scan the television uses to display the picture. The ‘i’ means interlaced and the ‘p’ means progressive.
Why does the amount of lines matter?
The number of lines on a television is important because it allows for greater detail in the image. This is a similar concept to digital photos and how dpi determines print quality. The type of televisions all of us grew up watching had 480 visible lines on the screen. By doubling the amount of lines in combination with the type of scan, HD essentially doubles the quality of picture.
Does it matter if the resolution is interlaced or progressive?
The type of scan is arguable considering the amount of lines for each HD format. Progressive scan is a better type of scan because it doubles the amount of times the TV displays the image per one second in comparison to interlaced. Still, the difference between 720p and 1080i is so minimal that is isn’t an issue at all. While 1080p is better than 720p and 1080i, very few programs are made in this resolution so it really isn’t a factor right now…and, it might never be.

"Unusable Signal"

Ok, I stopped short of going to Best Buy to get a new TV b/c my DAD suggested I pull the DVD player on another tv.

Dang it, he was right!. Same "audio no video" problem.

After playing with multiple buttons shooting blindly I found the [ I/P ] button restored the picture immediately!

This stands for Interaced or Progressive scanning:

from wikipedia

"Progressive or noninterlaced scanning is a method for displaying, storing or transmitting moving images in which all the lines of each frame are drawn in sequence. This is in contrast to the interlacing used in traditional television systems where only the odd lines, then the even lines of each frame (each image now called a field) are drawn alternatively."

So, my Dad says that "TV s are based on the interlacing" technology. I must have picked progressive scan while I was in the dark fast forwarding last week.

No progressive scan from component input

Sanyo DS27930 does not support progressive scan
DVD player must be set to interlaced scan

Split screen from DVD player, cable is fine no problem

It is not clear where you say input is from cable, do you mean the Scart input to your Sony TV? Do not use Progressive scan(p), as this is not interlaced. The normal TV requires an interlaced(i) picture of 50 half frames per second giving 25 complete pictures per second to reduce flicker. Some TVs and projectors and all monitors accept Progressive scan.
