What kind Of Picture Tube ??
 

Hi All;
I have a Samsung TX P2036, which it says on its manual is a CRT Flat Screen, So does it have a Vacuum and an electronic Gun, and Does it use High Voltage ?? Or some other Technology.. I am looking for something to do experiments with, like the ones done with the RCA Prototype, only without the Expense of getting an old CT-100 or CTC -2.. And still making something Color work.. Am I nuts ??? (Don't answer that).. Is this possible ??
THANK YOU Marty

In the description, it appears to be the old style electron gun, high voltage vacuum type CRT, that has been around for almost 60 years.
Yours is the latest version of the old technology. :yes:

Hi All;
I tested it and it seems to work, since its been outside since last fall.. The reason I am asking is the Manual says its a Flat Screen CRT, which seems to confuse the issue.. The Screen is Flat and Retangular.. It does have both a Video input and a Tri-Video input, besides the regular Antenna input.. Which means I can Build stages of Circuitry between the Tunner and the Video Output, Testing them as I go.. The only thing is that I can't Output the Tube High Voltage outputs, have to turn them down to something more reasonable..
THANK YOU marty

Well is it a big tube or an LCD/Plasma?

Take a pic.

Hi All;
Wiscojim, Yes, that is the set, They list it as a Flat Screen and a CRT, which is why the confusion.. I could pull the back of the set apart, just don't want to at present.. If, I can find out from asking.. For Now I will print out the Hoffman Color Course that I downloaded from ETF, and read that and see If it makes any sense..
THANK YOU Marty

Yes, it's a CRT. They just mean the front of the CRT is flat and not slightly curved.

Hi All;
OK !! Thank You Bob..

In the case of crt's, a "bulbous" screen is better but, if the people want flat screens, by golly, we'll give 'em flat screens! I think in at least some cases all they did was sorta build the glass out so that the exterior was flat, but the inside still had some curvature. Towards the end any non-flat crt was a pretty cheap model.

RCA's "TruFlat" TVs of the late '80s-'90s still used CRTs as well, but with flat (or nearly flat) screens. The tubes still operated as would any CRT, with high voltage in the kilovolt range, a yoke, flyback, etc. These were definitely not "flat screen" TVs as we know them today, as they were still designed for the NTSC television system (the DTV standard used today was still years away). I think the TruFlat TV's biggest selling point was, because of the design of the tube, there were no problems with reflections from room lighting or ambient light (such as bright sunlight), glare, etc. as was so common with standard CRTs having curved faceplates. RCA must have had a patent on this design, as I never saw this kind of "flat" CRT screen on any other make of television.

A friend of mine has got a Sony HDTV which is a widescreen flat CRT. It was from the early 2000s and cost him a ton when new. I watched a few hockey games on it, and it was impressive. This set used a Trinitron picture tube with a flat face but it was capable of full HD. I reckon only a handful of HD CRTs were marketed.

If that sony has the super fine pitch CRT then it has one of the best CRTs ever made.

I had the 30" wide sony HD TV. They also came in 34". We
sold abt a dozen 30's & a few 34's.
Hands down they were the best pix ever on a modern set.
They looked just as good on NTSC as HD, most HD's suck with
NTSC in my opinion.
They weighed a TON ! Finally sent mine to the dump, got
sick of replacing the power supply IC's every year.
Only other problems they had was FBT's.
It broke my heart................
Samsung also sold some wide screen CRT's & probably others.

Many manufacturers were selling flat screen CRT TV's in the early 2000's. I have a 14" Samsung, 20" Toshiba, and a 24" Toshiba flat screen CRT models. I know Sony, Panasonic, Philips, JVC, and third tier companies such as APEX all offered flat screen CRT models in the last decade. My 24" Toshiba is my daily driver. I like the flat screen CRT models mainly because they have a cleaner, sleeker, more modern look than the more traditional curved CRT's.

I was commenting on the Sony WIDE screen CRT's not the old
4:3 standard. You are correct that almost everyone eventually
used 4:3 flats. They all probably evolved from Zeniths flat
tension mask jugs they used in monitors in the late 80's. The
pix was drop dead beautiful & couldnt be touched by anything
for any $$$.

Wide screen CRT's I only remember in Sony & Samsung, Zenith but may
have been used by others. RCA had an earlier version that was a
real balls out set. I did go to the seminar but only worked on one.
The thing I remember was it belonged to a bum on welfare.
Why was I working ??
Its like I said about the first projections. "only for the very rich,
and very poor........".
