content: The most you'll find 'easily' is the connector pinouts where the unit connects to the vehicle wiring looms.Anything inside the box will be secret sauce and would have never been released. Maayybbee to a service repair shop or two, but being pre internet, you'll have practically no chance of finding the info now.If the trinitron CRT was a module that was used elsewhere in other products (likely) you might be able to find pinouts and adjustment information around if you get lucky.Do you have pictures of inside and out, including any labels etc?

content: Is it broken? Is it not wired up? It is unlikely there is much in the way of general information about it but if you have a specific problem someone might be able to assist in figuring it out.

content: James, as it sits it need many capacitors replaced + at least 1 surface mount cap is damaged.PCB 1-636-707-11 (bottom) needs runs repaired and 1 spot arced together, then it can betroubleshot for any other problems I do not have the vehicle at this time.Jeff

content: I think it will be easier once you have it in front of you. Capacitors and damaged components are easy enough to deal with, then if fixing the obvious faults doesn't get it working you can go from there.

content: James, I would say yes unless there is a TV tuner elsewhere in the vehicleits strictly a monitor the CD unit does have an opticle output also but ismost likely audio. The monitor has a 16 pin, a 2 pin and a 7 pin mini din.I might try a translator on the face as I know it controls at least 3 items(OFF buttons).Without hook up info all I can do is repair the visiable problems.Jeff

content: If the tv/radio/cd unit is JDM from Japan, then you have practically no chance of getting anything other than the CD working.AM might work, but most AM transmitters worldwide are gone.FM won't work as Japanese FM uses frequencies unique to Japan.TV won't work because Analog TV stations are gone and all TV is now Digital in most countries in the world.Hookup information is therefore useless.

content: FM can be sorted with an FM frequency converter/range expander (sure the numbers will be wrong, but preset buttons can make life easier), and the TV function can be hacked into a composite input by bypassing the tuner section, or maybe hooked up to a digital tuner.It's not completely useless, just will take a bit of effort and fun to get working.

content: cantata.tech, I am sure it has a radio section but its not part of what I have.IF it has a TV tuner its also not part of what I have.The monitor is certainly important to the operation of the systemand possiably more in the vehicle.There are many different things which can be done but will requiresome idea of how these items are connected to power and each other.Jeff

content: Quote from: cantata.tech on March 12, 2023, 08:36:58 amThere are loads of AM radio stations around, I have several antique tube radios that I use regularly.According to wikipedia "Many Japanese radios are designed to be capable of receiving both the Japanese FM band and the CCIR FM band, so that the same model can be sold within Japan or exported. The radio may cover 76 to 108 MHz, the frequency coverage may be selectable by the user, or during assembly the radio may be set to operate on one band by means of a specially-placed diode or other internal component." so the radio *may* work elsewhere in the world.There are lots of ways to get analog video, a Raspberry Pi or pi zero for example will put out NTSC composite baseband video so it would be easy to have a digital video player that could feed content to the monitor. It also sounds like it likely has other functions.

I have a selection here that I work on. As shown in the picture attached.I simply asked you which model# you had, that's all.

Nothing you've said is the least bit helpful to the OP and nothing I said has anything to do with tube amps. The radios I referred to having happen to be tube based but that's irrelevant, they're AM radios like any other, there are lots of AM radio stations.

content: Quote from: james_s on March 13, 2023, 05:18:16 amThat's incredibly rude and offensiveAnd btw, I don't even think the primary function of this unit was a Radio.It looks more like an early version of the Panasonic Strada in-car navigator. They're very popular in Japan and you'd know if you had spent any time there.So keep talking about tube-amplifiers and AM but I'm pretty sure that anything with a CRT screen would more likely to be part of an in-car Navigation system that the Japanese pioneered.Please try not to be so rude when you don't seem to know what you are talking about.It could be another brand, but Nissan mostly went with Panasonic over the years.Please seehttps://ndrive.com/brief-history-gps-car-navigation/for more information.

content: Quote from: Jeff eelcr on March 13, 2023, 11:55:46 amThat's right. Nissan used Clarions by volume way more than Panasonic.In Japan, they were sold under the "Addzest" brand.You might want to have this unit carefully examined to see if it is in fact an early CD Navigation unit such as an NAC-200.Theoretically, as a labour of love you might be able to get the maps decoded/converted and cut a new CD, maybe. I'd suggest it might have a Z80 or MC6800 processor? locally branded. Then you might be able to use it for driving around the block.If it is an original GPS, it's potentially quite valuable if it can be shown to work.

content: Quote from: Jeff eelcr on March 16, 2023, 12:44:23 amAs I originally thought, it's a Matsushita (Panasonic).The good news is that they continued to make them and the cables are available for later models. A bit of work with some tools can probably get a fit, if not I use a 3D printer to make up custom long-lost connectors.There will be manuals for later models that will be similar enough to enable you to get it to work (maybe/to-a-degree).
