    Holy moly...THIS WAS MINE! I couldn't believe what I was seeing when you showed the back with those metal strips glued on as well as the piece of masking tape with the hours count on it, but that was absolutely my CRT and yes, I was the one who attached all the strips on the tube! The strips were actually for geometry, not convergence. The convergence wasn't a problem, as I recall. But the geometry was a mess, and I tried my best to improve it using a bunch of home made strips, so forgive the ugliness back there, lol! Feel free to remove them and try your own hand at correcting the geometry, based on how you intend to position the set. I think I did my adjustments with it facing East. I hated getting rid of the set because it was quite low in hours (they original owner I got it from had it installed in an RV, hence the metal mounting strips) and the picture was very bright and sharp. But I could never overcome the poor horizontal linearity that plagues flats in general, so I ended up trading it for a 20" early 90s Trinitron. It's so wild that it somehow made it to you! This makes me wonder how close you are to me...I live in southeastern NC, and the guy I traded it to lives near Fayetteville, NC.

      LOL that's funny, well it's neat to know where the set came from and where it is now. I still have it atm but I'm not really adjusting anything since it all seems fine

      @@P-0-Seventeen Well, glad you're enjoying it. Hopefully the horizontal linearity doesn't bother you as much as it bothered me. I just edited my original post to say that the piece of masking tape was the number of hours it had on it when I checked in the service menu. Are you in NC? Just wondering how far that thing has traveled since I had it!

      @spencer6891 The linearity doesn't bother me on those even if I know it's an issue on some of the flat crt's. Usually the lineary problems are more barrel rolling and such during horizontal and/or vertical scrolling, which isn't as noticeable in curved sets

      @@spencer6891 We shall never know if he was near you or if somehow this magical set made its way inside of another RV to cross the country. I was curious to find out also after reading this amazing tale lol. I found a Toshiba 20AF44 on the curb and it looks very similar, just been trying to find out more info about this TV since I also found a sony KV-32FS210 Trinitron and an RCA TruFlat.

    Love my AF 14 & 20 inch sets. The 20 inch looks so much better after you unplug the edge enhancement thingy. Also Shiren the Wanderer is a fantastic game!

    A lot of people don’t know this, but you have a lot of tv models which show VM in the service manual but don’t have it installed. You typically only saw it in larger high end sets 27inch and over. My Sony and Panasonic sets show VM in their respective service manuals but neither have it

    Recently got a Sony KV-27V42 CRT. Learned it has Velocity Modulation and can be disabled by unplugging a connector on the neck board. Mainly using it for older consoles like NES, SNES, and N64. Should I disable the Scan Velocity Modulation?

    Hi! Someone recently gave me a 20AF46 Toshiba CRT tv with no remote. I don't currently have cable and want to just use it to play my old ps2, dvd, etc. I have been trying to get to video 1 or 2 but there are no input buttons on the tv itself. I tried combinations of both volume buttons, both channel buttons, turning on the tv with someone plugged into the input, moving to the channel under 2 and waiting on channels 3 and 4 but nothing seems to work. The button tv/video new remote universal doesn't work. Does anyone know of something I missed that can change the input?
    Thank you!

      Have the same model, they don't have an option to change the AV input without a remote. The model of remote they came with back in the day was CT-878, but you can also get a CT-90325 that'll work too.

    sorry but, at 3:00 i can hear a very high sound, i don't know if it's just me but when you film the tube (the copper part) there is a very high pitch sound

  • @riggles
    @riggles Рік тому +1

    Pro tip, mics pick up ~15kHz frequencies really well, a lot more audible in videos than irl. The 15kHz whine is really loud here making it a bit hard to listen for those of us who hear it.
    Opening the audio in audacity and cutting off anything above 15kHz before export would be nice for us viewers.
    SVM/VM is nice when it's adjustable through a menu since a small amount of it make for more accurate transitions between light and dark. Sadly a lot of manufacturers either just included a couple of bad preset or permanently on, where you get those brightened high contrast edges, that oversharpened look we all hate.
    (also, with the whine thing, you've probably seen me talk about reducing that whine on CRTs through sound isolating materials, or using silicone glue on things like linearity coils as sometimes it's those that make a loud high pitch sound instead. Figured I'd mention that here for anyone who has that problem and reads this)

    Hey I have a bit of a rookie question. I noticed that the red is ridiculously overpowered on my Trinitron. It is so strong it almost looks reddish orange on component and hurts my eyes. I noticed that RCUT was very very high in relation to BCUT and GCUT. Like 281 in the service menu. Would I just need to bring RCUT down to get a more natural red color? Green and Blue seem perfect, its just a really intense red.

    • @P-0-Seventeen
      @P-0-Seventeen  Рік тому +1

      Red push, it's something you might be able to disable in either the normal or service menu depending on the set. There are ways though by reducing red drive/cutoff to help but then you need to do a bit of white rebalance

    Are you a fan of the 20” Sony FD Wegas like the KV20FS100? I never understood why they nixed S-Video. Seems to have an awesome picture.

    • @P-0-Seventeen
      @P-0-Seventeen  Рік тому

      I never tried that one, but I heard those FS100's typically will have more bowing issues then others. Regardless it still seems pretty good but I think the KV-20FV12 is still sufficient

    how does the Orion tube compare to a Toshiba tube

    • @P-0-Seventeen
      @P-0-Seventeen  Рік тому

      Toshiba tubes seem to be better in almost every category, can't confirm since I've never owned one but I've seen pictures and they seem great. These orion tubes though aren't half bad, they're just limited in service menu options at times and can be a bit more prone to future issues like bad capacitors and such

      It uploads the vid first at 360p since 1080p takes longer to process, but higher quality comes later automatically
