Sony s MOST Dangerous TV - The KV-9400 Trinitron

Show video

hopefully I won't get zapped woo Yow today we're going to do something  super special uh I've been hitting up these estate   sales a lot lately just to try to get some CRTs  another old Tech and luckily for me I've been   able to find a few of them and I actually won  some items So today we're going to go and we're   going to pick up those items uh a couple CRTs  some other hardware and we'll see how all this   goes because uh this is always an adventure I  have to drive about an hour from my shop here   to pick up the items so let's go ahead now and hop  in the Old Mercury Grand Marquee baby and cruise   on up to a little town called Markham Virginia  just a absolutely beautiful drive here today   through the woods just wanted to give you a look  around this I mean middle of nowhere where I'm at   there's a nice big house that a lot of abandoned  properties back here and then really nice houses   but that's where we're heading back from I did get  the stuff and uh it's actually in the trunk cuz I   had to put the bicycle back here with me uh but  nice drive I'm going to show you all the things   I got here in a second cuz I think you're going  to have uh have quite an enjoyable time checking   out the estate Sal CRTs all right let's see what  secrets we scored not a whole lot back here first   off check it out did find this cool Sano tape  deck player now the problem with it is that it   doesn't have the power supply with it so it's not  a simple power cable it's actually got a DC power   supply right in there so we need to figure out  what we're going to do with that we'll take a   closer look at this inside especially if we  can find a power supply for that thing M7 7   00k by Sano now the real deal is this one the  Sony Trinitron baby look at this lovely cool   RF only Trinitron I think it's RF only wow yeah  look at that UHF and VHF my friends now this is   the KV 9400 and this is actually older than I am  it's from 1980 so we finally have scored a CR te   older than me man I hope this thing works oo it's  heavy let's get it down into the bunker and see   how it looks all right let's take an opportunity  to look closer at this amazing KV 9000 and we'll   even try a test run man it's got some color Hue  and brightness adjustments over here Auto okay   so I don't know that's probably going to be wild  looking if it's not been messed with in a long   time if it even turns on right if we look back  here we've got color controls screen this is our   uh back of our fly bag most likely entrance to  that now it does have UHF and VHF connections   as I said okay I've got some things set up here  first off this little RF modulator takes composite   spits out RF and that's connected over here I'm  thinking VHF is the right one I can't remember   off the top of my head but I believe VHF is the  frequency I want to try to get channel 2 or four   into I've got this little adapter that lets me  go coax into this old school antenna connection   so let's hope that will give us a signal now  when I turn on the famcom here I'll get a red   light there I'll get a red light here saying my  um box is on actually it's channel three or four   so we'll start with Channel 4 that means it's  getting a signal I do have the CRT powered well   plugged in not powered on and let's do it let's  go for an initial power test here of the kv9 ,000   oh my goodness I'm kind of nervous that it's not  going to work but let's just see what happens oh   I think I hear some life to the set let's see oh  yeah we got some scrolling oh we actually have a   screen here so let's see if we can figure out what  the heck to do even with this guy or how to change channels see7 two oh my gosh  I have no idea what channels   these are right let's try channel three on the modulator I don't know what channels these are  giving me right so let's go over here um whoops   so that's my thing there this is Channel  5 I don't know maybe let's go to this one   what happens when I like scroll this around it  says here turn knob until the design channels   properly tuned uh lower number channels  so I don't know let's see oh we're getting somewhere um okay this is going to take a minute  let me see if I can figure out how to use this old   tuning machine holy moly this is way crazier than  anything I've ever seen before but thankfully the   screen's working so hopefully it's just a matter  of us getting something on there uh to show up   so let me work a little bit more with this whole  setup and we'll see if we can't get a screen or   a nice image on there for you all right well  that only took me about 20 minutes to try to   figure out but you can tell I've got a picture on  here now just the normal picture I'm going to try   to turn down the brightness on there some so you  can get a better look at it we've got all colors   it did take a while to tune this it definitely is  the VHF and then I had to go in here and do the   old school tuning of a number between two and four  and that's what I've got here so let's just let's   just check out something on here how about Super  Metroid since it's got a lot of dark backgrounds   look at this I mean there's definitely noise  in the image cuz I mean it's not been serviced   of course but looks pretty good right now I love  that glass overlay or it's not glass it's actually plastic but yeah what do you think let's see  see if we can get some volume yeah we have definitely have [Music] sound wow so yeah  there you go interesting picture huh let's   turn it down cool well at least this one works  I did only pay $22 for this I think I paid 20%   fees on top of that so another $5 almost in  fees for the auction house and that's about it   probably going to do some more things with this  TV look at this this is an autocolor setting CU   you can adjust colors on it too look at that if  you like can adjust the Hue and temperature of colors I've got my CRT all torn open here I  thought I'd get in and see a little bit more   about what was going on inside of here first off  here's our tube number it's a 25A K B22 with an   orange Trinitron label that is made in Japan  here's our lovely yolk pretty nice Yol for a   9in tube and then if you see here I don't actually  want to discharge this tube that this is the weird   setup that is on actually the 2530 pvm which I've  never seen a breakout like this on a smaller one   that's kind of interesting to me this uh little  Contraption here probably yes it it is going to   control our horizontal static convergence if we  spin that wheel and we'll do some of that in a   minute when I start it back up but that means that  this has that style of anode cap where there's   like a little plastic connector under there and if  you mess that up it's really easy to snap a little   piece of it off and if you mess that up um you'll  never get the picture to look quite right and you   can't find a replacement for these anymore so just  a look down here it says where all our power and   deflection is down in here the flyback Transformer  neck board has a lot of color controls on there   everything's looking pretty good I mean I'm going  to clean it a little more but other than that   it doesn't look too bad over here's more color  controls and really tuning controls for the set   over on this side and U and if we look over here  this is the top I did take the speaker out which   is a nice shielded look at that shielded uh 1.5  wat 8 ohm Sony speaker and then this is the top   I've taken this all apart just to try to clean a  little more I'm G to try to avoid taking out all   the channel selectors and things this is about  as far as I want to take this apart but I'd also   like to get the screen out and try to clean under  the front but I don't want to take the whole TV   apart we'll see if this is even possible uh here  in a second I'm going to try to move some things   around see if I can get that tube maybe moved out  to the side over here a little bit and not have   to worry about tearing down everything cuz like I  don't want to remove the flyback at all all right   let's see what I can figure out all right well  the entire CRT as you can see has been broken   all the way down and I had to remove the tube and  the chassis and everything in one bundle like this   I could break some of these Boards out make it  a little easier but again I don't want to mess   up that flyback at all because if I do it is toast  and this TV is pretty worthless after that there's   another look at that tube number down there and  our deflection yolk right up in here then our neck   of our tube and then if we look over the boards a  little bit this is our CRT socket right there on   this neck board and we have some adjustments on  here but this is a really old school neck board   you see that's a primitive early design for the  CRT socket itself in there that Sony eventually   changed uh that's quite interesting but you have  color controls up here manual color controls by   these variable uh potentiometers resistors  resistant potentiometers that are going to   have variations uh then you can actually adjust  them from the other side so you have three colors   over here and then your drives for is that just  just green and blue there down here you have a   G2 adjustment and then over here is the focus  adjustment down there right there that's focus   and that can again be adjusted on the back side  thankfully it's got this nice plastic Shield right   here so you won't hurt yourself and accidentally  shock yourself when you're back here looking at it   that's a pretty nice touch a lot of this stuff is  pretty well isolated and protected so you couldn't   you'd have a hard harder time shocking yourself  with this than you may think but I'm sure somebody   could do it anyway that's a look inside here this  is our main board uh look this is our hot and our   flyback over here I don't know what do you think  has that been has that been worked on before I'm   not sure that's pretty nasty over in there just  some flux and stuff over in here I'm not sure um   but maybe maybe it was done in Factory a lot of  this stuff probably would have still been hands   soldered back in the day and so that's uh that's  all our boards broken out and the thing I really   wanted to do was clean up this bezel so that's  what I'm going to do I'm going to get in here   clean up the sludge and stuff from the inside of  this bezel and um the plastic overlay is actually   one piece kind of melted inside this Frame so  that's going to be interesting to clean cuz I   can't I don't think I can get that out of there I  haven't figured out a way to without busting some   plastic like rivets you see like is that a rivet  there and there's some things like that anyway I'm   going to do my best to clean it and then we'll  come and hopefully get it set back up in one   piece got a little bit of an experiment set up I'm  going to do some adjustments back here behind the   set and as I do them I'm going to slowly show you  what happens on the screen with my phone camera   up there so I'm going to set this down here and  I'm going to spin some of these potentiometers   over here move this there we go got that camera  set up so the first thing I'm going to do is I'm   going to spin this one for the horizontal static  convergence control and watch the front of the   screen I'm turning it and do you see how on the  screen you have complete separation horizontally   of red green and blue so the guns are just not  aim or the gun is not aiming all the colors in   the right spot so if you turn this horizontal  static convergence to the correct spot you should   have a uniform beam there you go if you go too  far the other way same thing happens blue green   red or red green and blue but you try to get them  all matched them up as matched up as best as you can something like that and that's how you  adjust it let's see the next one I'd like to   do is going to be the focus which is down here  I'm not sure hopefully I won't get zapped oh   woohoo Yow did you see that wo I did uh ground  my finger out on that stupid heat sink there and caught a little zap I'm sure you saw  that on the screen I will not edit that   out cuz I'm not a scaredy cat I'm just going  to have to do it again and I don't mean shock   myself so I'm not going to try that way  okay that's too big holy moly that was a zapino there we go I finally got it in  there now I'm going to spin it safely this time and doesn't really have a whole  lot of effect on the screen there we   go just a little bit of movement on the  beam not really worth messing with too much all right that's it for that here's the  front screen area and I want you to notice this   has a really light gray tube and partially uh  to help that is this darkened overlay that was   included on top of the TV and as I said before  you can definitely remove this now I was totally   wrong earlier you can remove this it actually  fell out while I was cleaning and if I look up   here there's a couple couple slots where it can  just slide in and you can do like that kind of   and push it in but before I take and put it all  back together I want to show you the inside of   the shell because it may be helping or hurting  I mean uh my reception a little bit on my tuner   and my RF signal look in here there's there's our  antenna right it goes actually through here and   and there's a cable up in here and I redid all  this uh and cleaned out all in here but there's   that and it goes around to this point which  is actually got a screw in it and that screw   comes in under here and connects in right where  my finger is and that's part of the antenna Loop   so maybe that'll help clear up some of my snow  I'm having very light snow issues on my picture   still but but I wanted to show you that here's  the inside of this shell when it's all cleaned   up uh there's some interesting pictures here  which I'll show you about the inside of this   it's pretty nice well I've been toying around  with the signal here a little bit more and I'm   actually not so much seeing a Clarity increase  from from adding that screw there now I'm sure   it's working better then and back to its normal  intention but I'm still getting a lot of um RF   noise on this set now not a ton but more than I  would off newer sets which I guess makes sense   for a 43y old tuner ladies and gentlemen what  you are seeing is the completely fixed restored   and ready to go Sony KV 9400 it is running  running and crispy beautiful RF here we have   a Super Nintendo and earthworm gym yes it looks  glorious and I want to give you one last shot of   this amazing CRT how about that looks so good  okay just to give you a final run through you   know we've got our lovely tray up here that I've  sent to channels and you can come in here and tune   to channel that you need to there's not too many  options at this point got our picture adjustment   and then our volume oh yeah so that's nice the  speaker right in here this is our antenna and   then our screen does have that overlay on it so  that kind of does help on the softer image due   to that RF fuzz which sometimes you get I mean  right now I'm not getting any RF fuz us it looks   really nice I love the patina on these old sets  just came out wonderful here's our little Hue and   color adjustment knobs down here and this is our  Auto color which it's off right now but it's so   tuned in that you can barely tell the difference  between on and off we have a brightness control   over here on the other side there's nothing  really on the other side there down at the   bottom you do have a couple of earphones for  mono earphone input there's our input board   right what a lovely input board how how high-tech  how wonderful of an input board easy enough right   well folks there you have it such a wonderful fun  little novelty CRT and you could play video games   on this like like it's sitting now it's not a  big deal but it's not something I would think   you would want to use is like your daily CRT if  you had another option and the great thing about   about this one is it's 9 in it's an iconic Sony  it's from the 1980s it works perfectly I guess   as intended you could say uh but all around you  could get much newer CRTs and get a better picture   experience unless this is what you're looking  for you know so I don't really consider this   a high usable CRT again more of a a fun novelty  beautiful art piece that works that you can get   a signal into if you go to more lengths I mean  right now I'm using a RF modulator and I'm going   in really with just RF into this set so anyway  what do you guys think what do you think of this   set does it make you want to buy more old sets  does it make you want to look for specifically   an old Trinitron Maybe let me know what you  think in the comments below and please leave   a like for me if you enjoyed the video I'll see  you guys next time with some more retro content
