Hi, welcome to a mystery teardown! What the hell is this thing? It's not the Luteum Q-36 space modulator. Let's check it out. Yes, we're going old school and thanks to chose that trio test, we've got ourselves a Philips PM 56:39 color analyzer for those playing along at home and this is an old-school bit of test kit. Comes in the original carry taste.

It's fantastic and let's take a look at it. What are we got? We've got ourselves the detector, which is designed to plug on the front of our CRT monitors and as the name suggests, it analyzes the color to see if all the colors are accurate and the spectrums are right. It's got a nice sexy little our control unit that comes with it and looks like one guy ourselves. The original brochure, is it No.

Well, it's part of it. There we go: CRT Color analyzing These would have been the Ducks guts at TV stations back in their day for calibrating all their studio monitors and stuff like that. Maybe they still use them. You know, some old school are places Philips use to make a whole range of, you know, various audio and video analyzers and all sorts of stuff for our you know, setting up, production measurement test, all that sort of stuff.

the old analog composite waveform monitor. Check it out. loudspeaker powered audio monitors. pretty fancy.

looks like they've You know, this is fairly modern stuff in the scheme of things, but yeah, I'm not sure when this color analyzer dates from, but yeah, it's basically no one would use it anymore, but it's probably still worth a pretty penny to someone who you know absolutely still needs it. But there we go. They're operating manual. Hot Orange my Danish Viewers Beauty made in Denmark is it but all the original menu authorities I Mean that's not.

Check out the old CRT TV that they're actually monitor that they're testing there. That is how. Yes, oh my goodness to our customers. On January 23, 1998, Philips Tv Test Equipments changed its name to Pro Television Technologies or P TV Who knew that? I'm yeah.

I guess they yeah, look to sell it off for pennies on the dollar for what it used to be. worse. Could I Moritz Von Toll put Anya There you guys, check it out! Wow Copyright 2000 It is recent printed in Denmark - thank you very much for playing. Oh so this is actually surprisingly recent although the model dates back to you know god that's got a date back to the early 80s I would imagine and maybe early to late 80s and but we're still showing this in 2000 now.

I Used to work at a key court back in 1994 I think it was and working on LCD monitors and things like that. so I was just starting to take over. You know, 640 by 480 was you know, 800 by 600 was absolute state of the art and it was real difficult for Mm. I mean yeah okay, people still have I still had a CRT TV in 2000? I'm pretty sure I did mmm jeez.

I mean how long did it last after that? Not very long I Wonder if they're still going? check it out. We even have the calibration data for our CRT color sensor CRT matrix What does all this mean I Have no idea protected data is that the data that's stored in the internal a squared prom I would imagine it's traceable to NIST No workers so this is a rather intimidating bit of kit. I mean look at that. That is fantastic.

It's got the suction cup to stick on that some sort of photo sensor in there which is, of course you know carefully young. Sure, it's very expensive and it's a quite expensive to get it I calibrate it as well, but there's not a probably a huge amount more in there are less calibrated in 2010. Stick that up and stick it on the CRT monitor and get an accurate to see the spectrum and your color values. so you could get in there with your tongue at the right angle and tweak your RGB values to get your monitor the right color.

I Used to work with a guy way back at Pacific Communications back in the day who had calibrated eyesight I kid you not the job was to they would be sort of. Their eyesight would be certified to actually look at colors on the CRTs and know that they're accurate. It's got the correct color, the the hue, the saturation and or brightness or whatever you know and they could basically do it by eye. But this is a basically a you know, pretty much replaced people with those calibrated eye sites I think and yeah, you know you have a numeric value that you can get with this thing.

So let's actually trying before we total violate the rule and we'll turned on before we take it apart, shall we? It comes with a little plug back with a weird ass attachment. It uses a rechargeable NiCad nickel metal hydride battery pack. Letsa let's try and switch it on. initialize in and Bingo! There you go.

there's your RGB values also. I've got that sitting up I'll stick it on the up. There we go. Yeah, I've got it face down now so it's not receiving any light at all and we can get outlook candelas per square meter.

Believe it, you can't use this on like a modern LCD panel. It wouldn't work. It hasn't got the the right color attributes and everything else is designed for CRTs I Believe they did have versions for LCD monitors. They probably still do to test the color because you know you get one.

Always professional color monitors these days. I'm talking about the multi-thousand dollar professional monitors that are all color balanced, color matched, and things like that. Well, they've got to test that and you know, presumably they stick on something similar. So if I point this up to my lights up here my studio lights, there are nominal six thousand Kelvin Color temperature RGB Fairly well matched I mean I Could you know I Spectrometers much better I could get my spec domitor and hook it up I did that in a previous video did know there we go temperature around about that 6000 Kelvin So that's yeah, that's pretty spot-on Ensuring a high standard Picture quality has become even more important with the increase in interchange of program material from different sources such as TV studios and production houses.

The Philips color analyzer assist in this process by meeting the demand for easy control and adjustment of the color white and the brightness on any color monitor. Beauty uses an adaptive system to establish the correct measurement independent of the field rate. The instrument works for field rates. HT HD TV Systems progressive and interlaced system Bobby Dazzler Main application is to align the color of white and brightness.

Color monitors in studios OB Vans are outside broadcast Man for those not in the know, post-production etc are measuring monitor surveillance monitors RGB Computer models consumer TVs And here's our XY Y measuring mode. Here this is plotted on a chromaticity diagram some mouthful and the x and y values and the luminance value y and the color error CIE love, hence why it's called CIE are shown in the numerical display. User can select a preferred measuring unit of Luminance candles per square meter. Nits like the nits or the foot Lambert die or you foot Lambert Fanboys Come on, admit it, Who's a foot? Lambert's and bully.

Now, if you're wondering how this works, you can actually set up this box. You have pre-programmed different setups specs that you want and this box. You actually want your dot to be inside that box inside the RGB matrix with the luminance and the XY value. so it's got to match your pre-programmed one.

So I can stick it up there to the lights and blue and bingo we are inside the box there smack bang in the middle, so that's you know, Whatever we've got it programmed up to. Yeah, we're certainly meeting it. Inspect ship earth and here's an interesting characteristic curve will go: a portion of the CIE 1931 XY chromaticity diagram showing the daylight locusts that Planckian locus. Importantly, with a few ISO temperature lines obviously I it's perfect sense.

So the field of color, imaging, spectrum, and luminance and all sorts of stuff is actually quite complex when you get into the physics of. and I've done several videos on that before touching on that sort of stuff. So yeah, it's a rather interesting field and it's of course it all comes down to physics. There is our battery pack anyway.

Um, yes, that's enough. I Won't pretend I know all about colour television. You know, reference check in and stuff like that. But let's have a look.

What's inside this thing Might be a huge amount. This will have a micro in it'd be interesting to see which one and the this will probably just be a sensor and some driver sensor electronics. Something like that. You bet we're going to break the orangey void.

If not remove, stick up. Here we go. Let's get in there and will we be in like Flynn Well no. we have a spring.

Okay, sweet. we have a spring in there for the trigger. That could end badly. Ah yeah, we're off.

Yeah, there's a little bit of stuff in there. What? Yep, the trigger is. yeah. what's going on there? Hmm.

yep. broke it. Don't do brittle plastic. It's old so let's have a squiz inside here.

Of course it's all in the calibration of this thing. No, that's that comes at all. Actually, that's rather interesting. Tada.

We have three separate ones. RGB Oh, it makes sense does it not that you would have separate RGB ones with different filters down there? and look at that. Oh Get a close-up on that now. I'm going to guess that these photo sensors are all identical and the way that they of course ones are for our ones 4G and one for B And the way they do that is to have the filter in there.

There you go and you can see that they are actually different. They would be the RGB Yeah, that says how to be the red. that would be the green and that would be the blue. even though they don't necessarily look 100% like it on here.

but yeah, that's how they're doing it with these little lenses. I Won't bother taking I could I Don't think there's anything else under there really, but hey, why not? And if you're wondering why they're all angled like that, it's obviously too so that they focus in one point in the center like that. I Don't know what the actual field spot size would be? Maybe it's in the specs I Don't know. Um, but yet it's designed to focus on one little spot there because there's no point if you're aiming.

you know one here. one here, one here. that's you know. Too far apart.

you've got to aim for the correct space on the CRT itself that you want to measure. So it's a spot measurement thing. There you go. that's a better look at the filter lenses for those playing along at home.

this is what faces the CRT and they're the red, green, blue lenses. only. beautiful. They're probably worth, you know, a pretty penny.

I Would say that'd be a very specialized bit a kid I wonder what they like like that you know the spectrum bandwidths of those are I Don't know what does anyone know? Does anyone want to hazard a guess as to you know how narrow the the filtering is on these things? But anyway, yeah, they do look really. Josie I Love it. And on top of that, in case you're wondering, is just what looks like I'm sure this is kind of special too. I'm not sure what's going on.

there looks like something's something's happened to that. mm-hmm I don't know, but yeah, that looks kinda sorta special as well. and maybe the front part of that as well. So yeah, there's lots of spectra me magic happening through these three layers here.

Well, it turns out we don't have to wonder because I've got a spectrometer. So let's actually use my spectrometer to measure this. We've got our filters here. our red, green, and blue filters I've taken the front part of that off.

but we can measure that separately and you've seen this spectrometer before on the block. And here we go: I've got my little torch here just to make out. You know, a bright and broadband sort of source? It's not. You know, this is not completely scientific.

This is not the best thing. but you know we get in a reasonable coverage there. It's going up into the red as well. You know it's peaky, but it'll do the job.

So let's actually hook this out. or actually I'll show you. you can see that's red filter is the blue filter. Maybe it's not going to show up well on the webcam, but that's blue and that's green.

Fantastic. Alright, so yeah, that actually did show up so let's actually shine our torch through here. We go. What do we got here? Blue? Okay, so if we hook up, you'll notice that we're getting absolutely nothing when I point it away.

So I've got the gain set so that there we go. Bingo. That's the bandwidth of our blue filter now. I'm not sure what I was expecting there.

Maybe something a little sharper than that, so you know it's going from 400 to 550 nanometers. Well, there abouts. And of course, if you put it back through like that, it's more broadband than that there's You know, there's still content below 400, but you know it's like you've got to get the gains right and everything else. I'm just mucking around here, so it's not certainly not the best science scientific experiment.

but you'll be able to see the bandwidth. And likewise for the green one. Bingo. There we go.

chopping out. You know, from four, well, mostly from safe 502, sort of 700, 650 or thereabout. certainly in that green spectrum there. And of course, we are clipping a little bit.

Of course it's hard to. Oh, there we go. You know? Anyway, you can see so the green is a bit wider in terms of band widths and the blue one I'd say ah, no, maybe not when you include that little aqua hump in there aqua hump. Word of the day, let's try the red one and that hello that is.

That is. surprising. the red one that's still oh well. The yellow content there? I Guess but what is the blue doing? The blue is almost the same.

Well, it's not almost the same, but you know it's getting up there towards the green peak. So why it's letting through blue in the red filter at like 450 nanometers there? I Don't know. That is quite strange. and as you know, its main peak is about 580 nanometers in the green spectrum.

basically where we, you know, not far off where we. yeah, basically the same where we were before. So I'm not sure what the deal is with that red filter and it's very unusual if anyone knows what's going on there. I'd have to look into the physics behind that's think about it a lot more.

But anyway, that's interesting. So the bandwidth. Now let's take this filter material and look at that. There we go.

That filter material is taking out all the red. What? Why I Mean this is a red, green, blue or what? Give me a break. That's just ridiculous. Now that's well.

here we go. Hang on. So Wow Okay, that's the similar sort of response to what we saw with the red. and with that and this just, it's given the same response.

What? Oh no, no, no okay, no no. There we go. That's our white. so that's our spectrum.

Maybe yeah, this lead isn't the best. I Think maybe that's what's going on there. We don't have enough. Yeah, because it's autogain and we didn't really have anything in the red to begin with like there's some there, but because of the gain and everything else.

No, we need a better light source. but why it was passing that blew through? Fascinating. So there you go. But they're the filters that we've got inside this thing.

and you can. You really saw like, like the blue one for example, very and blue and green. Very nice. Our bandpass our performance on this thing.

So there you go. That's the filters. Neat. cool wonder if you can still get the service manual for it.

And for those who just kind of get enough of the specs of this sort of thing, the measurement range. There you go. Accuracy and look, there's a repeatability luminance. RGB Bars bevel 1% of terrific stuff.

and it even has a learn mode if you don't know what particular phosphor of the monitor that you're actually testing because that's important. So do the filters inside here actually are parallel. The color response of the human eye as defined by 3 1931 Standard Observe occurs. Um, that's probably what they're attempting to do here, because that's the thing.

What do us humans actually see this monitor as? I Mean that's the important thing. You can do all the measurements you want, but you know if we think it's out, then that's out and just a close up there for those playing along at home. Psychedelic Man and we have hot snot. Thank you very much.

And what do we got over here on the board that is, we're going to have to get our knife out for that only. I Have we got a little? Phillips probably. you know, like an 805 1 or something. Do we have an 805 one? Come on, let's cheer.

Do we have it? The 87 C-51 I called it. what else would you find in this puppy? But apart from that, and though it's what our fan is, some maxim parts, there may be line drivers of course. dead giveaway right near there I Don't know why they put the verdict resistors in there like that. That's rather hilarious all hang on the bottom of that resistor.

weird purple things. Well Wow they've actually gone to the effort to put a sleeve on the bottom of that I am doubting that's a resistor now I think that puppies and inductor and of course you got a hot snot. your sensor in place, don't you? I'm Dean Can we get a part number? Nice little plastic holder for that, but I don't see a part number on there do Oh Bummer. Anyway, if anyone can identify that the quite large sensor died in, there isn't it? Just got the one one bond wire you can see going over there and and it's really interesting.

Like I said, all those would be identical and all the filtering is of course happening on the front. so they would be, you know, wideband photo sensors of some description and of course they'd be doing all that still. Turing with those front lenses. however wide the bandwidth is for the IG and B that's pretty much all she wrote for the sensor board.

It's got a fair bit more than I expected in there, so it's obviously are digitizing all that. 805 1 was there a little ADC on there are there might be somewhere a Philips ADC come on. Wow Yep, there it is. They got some serious business happening here.

This is a TC 500 A but that's what the microchip symbol but I pulled up when I Googled that pulled up a microchip datasheet. This is a an analog-to-digital front end. It's an entire front end up to 17 bit ABC with you know, pretty much the whole shebang inside that thing. so that's an interesting bit of kit.

Date Code: 17th Week 97 So let's open the main controller here. Hopefully good all out. We had neato 5-1 before. Well, the context of the battery just soldered directly onto the back.

There we've been. Moon. We've been mooned. We're going to get it out.

So we had I had an 805 one before, but that's all we needed to send that you know, packetize that ad seed control that ADC and stuff. read those values, send it over the serial line they will get in power over that line of course. So let's oh. I'm going to board the board.

Yeah, yep. Single in line I Love single inline board to board stuff and we're in like Flynn Have we there we go? Tada, we're in like Flynn as our LCD stuff, right? Toshiba I'm going to say probably sharp job' but not that's a Toshiba and what do we got down here? Good old-fashioned microbes. So we've got ourselves a rom and all the best stuffs made in Japan What on earth is that said at 13:30 Hmm. Aha, there we have it.

Phillips ECF 8 OC 31 Basically the same as the 805 one except there's no rom built-in hence well we've got a separate ROM there checksum 7900 since to even to me sure enough, that said 1313, you googly that one end. it's an LCD graphic controller of course because you know this is just for driving the segments. so you've got to have the actual wire controller. It's all senses, you know, pretty old-school stuff.

I'd Love to know where this when this design originated from. you know it would be maybe early 90s. it could be the late 80s, perhaps. But obviously though, I'm making this um, into the 2000s and I like to know when they discontinued it as well.

So there you have it. That's the Philips PM 56:39 a color and Liza thanks to Charles for donating this one. It was just going to get tossed. It's like so old you can't find anyone to really who wants this sort of thing anymore, but hey, nology would still exist for modern calibrating modern LCD monitors and stuff like that? I'm sure.

but yes, CRT is gone a little bit the way of the dodo. but I don't know if you're still using one of these, but when was the last time you use one of these? Let us know. leave it in the comments anyway. I Hope you found that mystery tear down interesting.

I Certainly did. Hope you enjoyed it and if you did, please give it a big thumbs up. Catch you next time you.
