Hi my name is Mess Bank up I'm from Denmark and I have been doing electronics as a hobby for about ten years. I run the Kaiser Power Electronics the DK block and also with this YouTube channel associated to it I primarily do with high-voltage high-current and Tesla coil building and I have done quite a few from small to large and I also do a lot of tear downs in expensive exotic decommissioned equipment. So I hope you will enjoy this video and a huge thanks to Dave for giving me this opportunity to reach out to a much larger audience for which I think my channel will be interesting Hello I'm Mess Bank Up and this is Castle Power Electronics. This is a Sony call a Video Camera Model Pvp 7ap and if you have watched any broadcast TV transmission live or recorded in the 90s, there is a good chance that this little baby was used in the production or the live transmission.

It features a huge fortune on 8.5 to 119 millimeter lens and it's a real heavy camera. It's very big and as you can see the size of it and this isn't even the whole story, this is just a camera and a communication unit. There is no parts for recording or starring any kind of data in this that would all sit in the central control unit that I unfortunately can only show you a picture of and I have made this camera run alone by just finding out what Vol sets and where to put them. Let's take a closer look at the the camera itself.

Here we can see the marking plate with the model number and DC voltage. The back part here says that it is only to be used with the central control unit 354 355. At the front we have the 14 on 14 times zoom lens which comes with a nice handle for zooming with a motor assist. In the other side we can see the nice three CCD shield now all around the the camera.

There are so many knobs and buttons and so on. But here at the front of the viewfinder here are all the controls for setting a brightness and contrast and peaking and so on for the viewfinder but also has some audio controls for the built-in microphone. The underside here we have some different white balance settings camera shutter gain output also another white Bama balance switch and up under here there is a selector for color filter temperature and hiding. again.

Up here is a shara on/off button along all these which mainly associated to the video part. Then here at the back is the intercom controls and this goes on both side where it also has a plug for the external microphone that the interviewer would use. Then at the back here we have all the connectors that goes out to the CCU. Now this have a power cable and then another.

two cables here for the CCU and one for VTR I. Have not been able to find a price tag on this camera but I am guessing that it was not low at all. It is a multiple. they built camera so the whole unit here at the back that communicates with the central control unit only sits here with three screws.

Then you can actually take the whole unit off and I think you could replace it with a recording module so you could do four for mobile recordings now. I Have really looked forward to show the show you this part that is inside because it was absolutely nothing like anything I Expected I Did not expect to find a small rack mount computer inside a camera, but here it is small beautiful carts, all custom tasks that we have the little CPU board sitting at the bottom. There is some audio for the intercom amplifiers, another this says red, green, blue so perhaps a little test pattern generator and over here we have everything that has to do with the sensor for the image generation which is hiding behind this little black cover. Here we can see the two power cuts as this is a European camera but I'm completely amazed about how how beautiful beautifully built this system are.

You can take out these small carts here. this is the first power count and I really can't tell much about this right now. I See it has a little bus connector. It goes down here at a small bus connector at the motherboard at the bottom and I assume that the PS cap that we have over here at the right side is the power supply, but what the other here does has a lot with the black setting, test level gain Gamma white, clubbing FL RPD these are some shots short instead.

I Do not know, but I'm really looking forward to taking this further apart and show you what is this and I Think that from I can just show you an example of the image quality that this camera can do right now just up here in the Wrights right corner of the picture that it is not impressive. These sensors are not doing that well. It was only made for seven hundred lines of TV resolution and by today's standards this is nothing to really use for anything but I Did find a cheap pal to USB converter on eBay and I will see if I can find the PAL output on one of one of these cuts and see if we can get this to actually stream something live to a modern. PC The racks are now empty and this camera is absolutely madness.

It's incredible how much stuff they have gotten into so little space and with so many wires going all over the place I mean assembling this have not been an easy job. There is simply just wires going everywhere. So over here we have a high voltage supply which I'm not sure if this is D Sensors require a higher voltage because the camera is supplied by 12 volt. DC But yeah, I'm sure we will find out.

So I take out all the bolts and let's take a look at them here. We have a the presser support I'm not sure if this is just for the CCU or also the other analog image ports, but it features a small micro controller and a Ihram which says sine video broadcast television equipment to rent higher. So perhaps this camera was only rented at first and then later poured out. Then here we have the two ports that was marked empty and the sea level I'm not completely sure what they do.

They have a few trimmers, but also has a thirty six megahertz crystal here and you see the I See, it's a 74 if 175 PC So I can look that up up here. We have the two microphone amplifier boards. This one is for the intercom and this one is probably for the external microphone. Then we get over to the analog image boards.

First over here we have the power supply. It's a old switch mode power supply and a little funny thing, see the two front transistor sitting up here. Not really enough space for them to have good enough cooling sitting nature next to each other so they just bent good around with a little insulation on the lacs. Then here we have the this port was marked A.m.

and Tell and this contains a lot of the says PR and also has a lot of balance pads but not near the amount that we see on this board. It's absolutely insane having to adjust these boards when they have first been built and I going in for calibration Must be nervous. must have been some some job to do that. And over here we have the first power board and it actually has a I think it's a crystal for the panel frequency.

So hopefully on this board I can find some test points or something else where I can find a clean pallet signal to inject into my little USB converter. Now over here I will also remove the cover or the print that was sitting over the sensors. Here we can see the sensor port marked G4 green and you have R for red and B for blue. Now all these white wires then connects down to the different sensors that we cannot see right now.

but I will remove the lens assembly and then we can take a look inside the sensors how the lens is taking off and here you can see one of the reasons why I'm doing it. tear down on this. Then here on the UV filter it has I don't know what you call it glass paths are there is a This camera has been sitting outside in bad weather. it has taken a lot of rain so unfortunately there is now some something between the layers in the UV filter and it's completely useless to get a proper picture through it and there is no way to really clean it or get a new one.

I Could probably find something and cut it to fit, but I'm not sure I would get a good picture afterwards and even then the resolution of the camera is simply not good enough to keep it, but it seems that I will have to remove the these screws and I will see if I can take the whole front off and get into the center ports. This is just a incredible amount of wires going everywhere. I Know I said it before when we looked at the the main board at the bottom, but this is just ridiculous. There's an absolutely ridiculous amount of wires so entwined that it's almost impossible to get this taken apart.

As you can see the whole head of the camera is right now in a yeah let's just call it the exploded view. But what we have revealed this up here, we have a 29 five megahertz crystal sitting along with something that is shielded beneath this little golden metal plate. Over here it seems like a power distribution board up to the three sensors and the brown funnel thing. Here is the optical color filters where we have the red part and the green part and the blue part.

Here for the three different color sensors that is all glued together and in this assembly. I Don't think I can get this further apart without risking to to break anything and I really wouldn't do that I Assumed that the tube back plates would only reveal the backside of the backplanes and I did wonder where the controller for the whole backplane actually was and here it is. It's a Hitachi Hd60 305 which is a CMOS microcontroller. It's a 8-bit CMOS MCU with the two kilobytes of RAM and 128 bytes of RAM.

Now this has 31 I Oh pins and this is what along with the massive amount of custom parts custom boards here which is stamped Sony makes up the backplane and it just keeps getting better and better and better. This camera is absolutely stuffed with parts. Yeah, III just I Can Can't describe this anymore because it just keeps popping out from every corner and so on. So this is the backplane board of the intercom and CCU unit and this basically encodes the signal into a special high frequency combined signal of audio and video and so on to the CCU unit we're decoding is being done and then over to the power format again.

So maybe I could also here at the inputs find something I can use at the power to USB converter or else I did also notice this because this I actually missed them early on that it has a little plug here that says test out and it has a PNC plug. Who knows. maybe this is just a pal output but taking a view again. Massive amount of wires going everywhere and unfortunately I do not have been able to find a manual for this.

Every site that has one would want me to pay for or for it to download it. so I did not want to waste money on that. but this has really been a been a pleasure to take apart and look at because this is a stunning piece of engineering. So I will get it all together again and hopefully no parts are missing.

Never sync small screws and yeah it will run again. This is kind of the test setup. It's a setup just with a adapter. Then I'm using a cheap DVR to USB converter that I found on eBay.

It came with a lovely software here called the TVR which also came with a serial number in a text file so that is probably seriously it lit yet. and then I have my green screen. so let's see how this camera really looks I will use my good friend here as I would say Carlo tests on the camera. So here you can see me film from the front front camera of a modern smartphone.

but now let's see how it looks like on the old analog video recorder. The resolution on the recording here is 720 times 576 pixels. It's encoded in Mpeg-2 and this is given in a whopping 3.6 gigabyte data per hour. So yes, this software actually gives the data rate per hour.

So how do you like the color difference between the smartphone camera and then the old analog is suddenly certainly much more soft down and I see that there is really an issue about setting up White Balance? probably. and because it's all manually controlled, you have to set up the scene ride. and I really can't see how anybody would have worked with this. It quite takes a cameraman when you can compare to a phone camera like this.

We just push record, you get an instant good result. It takes care of another thing for you because this is just a massive load of work to make anything good. But there is also that little difference that screens that we are looking at today are so much better than what this is original design form so we can't really compare it. but at least we can see what it can produce on today's hardware and if it's really useful for anything, if you need to do the song in we mark that forum and you find the appropriated threat I will put a link down description of the video and here you can have a chance to win this camera.

If you have a cool project that you would like to use it for our take it apart and build something completely new which I would really like to see because as a whole piece. I Don't think this camera has much to offer in today's digital world, but please do comment on what kind of project you would like to use it for and it can be yours theirs. However, that little caps that this is a heavy camera so you would have to pay me for shipping it to you and that is in around maybe 50 60 euros anywhere in Europe So be aware of that. Please ask me about the shipping details if that is a problem but I hope that somebody will bring new use to this camera I Hope you enjoyed the tellin I hope you enjoyed seeing the camera itself I hope you enjoyed seeing what it can do and I especially hope that are you really enjoyed that the encoder is just not working that well so the image is a little stuttering and the sound keeps lagging behind and so on.

So that software that follows with the DVR to USB is completely useless. But I'm not going to try to use any other software because for me this project is over. This camera is looking for a new owner and a new future. So until next time.

See ya.
