Found a modern day field sequential color tv

[Dave A]

Mine arrived today in the same condition CRT described. Opened as stated in the listing and also missing the AC adaptor. Mine also has minor scratches on the front plastic screen cover but not another scratch. Nothing that Novus #2 would not cure. Having read the sellers listing I got what I expected and did not want to challenge him. I will deal with it...unless he tries to sell adaptors separately. Stay tuned.

An old Gateway laptop brick popped it right to life out of the box with no video connection. It is a cute little thing from 2000. Just pushing buttons showed a 2-69 tuner inside with a scan available. Too bad nothing to scan but a dedicated RF source if needed. The surprise was the video input was set to PAL and no switch to NTSC. Rats. I also suspected this was a factory default and some local sensing was onboard. Correct. Hooking my DVD to the set flipped the input to NTSC and all was well. The audio was dreadfully low from the speaker but with earphones it was fine. This set was a field set and you would have been on phones anyway.

I played some old TK stuff I have on DVD and was pleased although it was not as sharp as a modern signal and a few generations old. The old TK color on-screen was a bit subdued from what we are used to. It is not lollipop color unless you crank it way up but very normal looking. It did seem to have trouble with flares in the lighting and they showed as offsets from the flare as a separate red trace. The BW setting showed mine needs a bit of blue gain needed.

Etype...I could use the manual to fix the gains.

I took a bunch of photos and they were hard to do to show the pix given the low light. I loaded a few. They are more true color because of the camera. The real screen pix is a bit warmer...missing a bit of blue...and my camera fixed that by itself.

While taking the pix I got a few photos of the R or G or B image by accident. I could also see the RGB by doing the old fan-your-fingers past the screen and see the artifacts. Much like the old white baseball flying through the shot as separate RGB colors on mechanical sets.

Overall, I am glad I got it. It is a bit of ancient technology that JVC dusted off 50 years later for who knows why. What were they thinking other than a higher definition field set that showed color? And who owned the patent at this point?
