FJ60 Stock Radio Schematic diagram?

[JLH911]

Has anyone ever seen a schematic for the stock radio on an FJ60? Not a wiring diagram, but a component schematic diagram of what's inside of the radio.

I have one that I created but is IP of my business.

Wonder if Toyota ever made one. I might have to write corporate.

It would likely be the manufacturer that has the schematic. I don’t know if that was Fujitsu or somebody else that made it though. Or just send it to @Engineer8000 and it’ll come back fixed. Or trace the circuit yourself.

I'm looking into trying find someone/somewhere that could show me how to troubleshoot it. I stupidly reversed the polarity on the power leads on an already working unit and must have damaged something.

Reverse polarity is a pretty common fault and usually takes out specific components, depending on the type of circuit of course. If you don't have prior electronics knowledge, why not just send it off to somebody who does? Trying to fix something like that can end up causing more damage and turn the whole thing to trash.

I have tracked down the service manuals for many of the early toyota radios. Some are on microfiche. Some, like the 60 series and hilux pickups I have had to spend the hours to figure it out on my own.

I have some limited experience.(High School/College) I have a decent multimeter, soldering iron etc, but nothing like an oscilloscope. I guess I should look into a course maybe online or something. I have many things I'd like to fix and would like to be able to fix them myself and not have to bother people for stupid mistakes like this.
