Thanks Tom, I was thinking they were the same since I see it so often. S-video output from a Channel Master CM-7000 set-top box looks especially good on this set.

The same thing happens when a "VGA" input is mentioned. That connector is called an HD-15. VGA was the IBM name for their (then) high-performance computer output signal, Video Graphics Array.

Well, I've tracked down a high-end Sony locally.

It doesn't have S-video though, which concerns me. Why is that, I thought S-video was designed in 1987?

In any case, what do you think? I like colors, and those early 90's sets that I remember had fantastic color.

The quality of the picture also seems to depend on the quality of the TV. Some TVs have excellent pictures with RF, while others look awful over S-video.

Should I also check for anything? I know streaking reds are bad, but not much else.

Many sets that had video inputs omitted S-video since many consumers didn't have the good quality equip to take advantage of it.....It seems a bit more normal for an older Sony to lack it as they were the pioneers of the Beta video tape standard which they were by then having to begrudgingly drop due to poor sales at the time (I seem to recall that S-video was made to go with SVHS decks).

Y/C connections go back at least to the Commodore 64 computer in ~1983 (but not with a four-pin mini-DIN connector). S-video connections were a step up from composite video, so they were not universal even once composite inputs were.

Ah, I see.

Is there anything I should check when I look at the TV?

In the 80s and 90s, I was a pure Sony snob, and I bought only their top-of-the-line sets. From 1989-1995, I had a Sony XBR Pro 25-inch monitor with separate tuner that displayed an amazing picture from Laser Discs and was quite good with broadcast signals as well (and cable on the channels that had good signals). So, I do not know much about other brands or lower-end Sony sets in those years.

To evaluate a set of that era now, you should set the color control to minimum (so it looks black-and-white), and watch the overall tint of its picture when first turned on, and also compare the overall tint and sharpness with the contrast very low versus very high. If it is anything other than proper shades of gray during these tests (other than in the first ten seconds or so when first turned on), or if it gets blurry with high contrast compared to low, then the CRT is quite possibly weak. (Very small amounts of off-tint can be adjusted out with internal service controls, though.)

You will need to use a digital-TV tuner "converter box" or a cable box with TV channel-3 output to test any sets of that era, if you care about the RF input; many Sony sets had problems with their tuners in that period.

Thank you very much for the information.

So this set isn't a high-end set?

It does look like a nice set in the pictures I found.

If a high-end set in 1990 had composite and optional S-video, what would a high-end Sony TV have in 1996? Component? Flat tube?

Pretty interesting.

My parents bought a 1991 (close enough to this topic's era of interest imo) 19" Fisher TV that lasted untill late 2001 when the picture started developing a strange folding over, warm up expansion/stretching problem (image was collapsed and folded over on startup, but continued to expand over a half hour period). It had bad caps somewhere I'm sure, but when it worked properly, it had a beautiful picture. It had remote control, stereo sound, on screen display, and composite A/V inputs with audio output. Still probably one of the best TV's I've had.

In 1990, I would expect S-video, dual tuner picture in picture, and a comb filter in a high end Sony (you won't find PIP on anything under 27" though). They also often had a way to connect external speakers, or to shut off the internal speakers to use an external amp. Component video didn't appear until the late 90's (after DVD came out). Some high end models from the 80's had an RGB input which can provide the same picture quality as component (requires a component to RGB adapter to accept component). Sony didn't make flat CRTs until the late 90's (they were actually the first to sell TVs with a flat CRT). Zenith did make flat CRTs in the mid 80's, but they were only for computer monitors.

If you want to be sure your getting a high end Sony, make sure it says XBR on it.

Thanks for the information, Andy.

I've always felt that 27" was too large, 20" was always the perfect size for me. But for every 20", there seems to be 5 27" Sony sets. Kind of strange.

I guess I'll just hope to find one.

Let me just add this:

TVs with RGB input, usually, *will not* accept component video.

Reason being, component video uses YPbPr encoding. Its luma (Y), blue difference (Pb) and red difference (Pr). Yes, it uses red, green, and blue cables; but its not the same as pure RGB, which is basically sending a full bandwidh luma signal of each color component.

When component video started becomming standard, a lot of people thought they could get a VGA to 3 rca adapter and hook the TV up to the computer. Sometimes it worked; the computer would output a proper HDTV YPbPr signal; or the TV happen to accept an RGB signal.

I finally found one, a Trinitron KV-20TS20. It's from 1989, and doesn't have s-video, but I figure it's the best I'll find.

Sony and Toshiba were nice, but the CRT's did not have the longevity, so take a good look at the picture.

Sony's were a decent set; but, the CRT's tended to go bad after a few years.
The CRT on this Sony is strong, I guess it wasn't used much. How can I keep it strong? I reduced picture from 100% to 50%, and calibrated the black level (which was already pretty much perfect for 7.5 IRE).
