powers on, but doesn't work fully
Same, to be honest

The light inside is broken but I still work.

I posted about this some months ago: https://poal.co/s/oldtechnology/774380
I finally decided to try and bring it up, as I'm cleaning things out in preparation for donating unneeded things to a local place that auctions stuff off for operating funds.
I decided not to use my death cheater but instead soldered a power cord to the input connections. I just rawdogged it right to the isolation transformer. To my surprise, it came up - but no sweep, no movement of any sort, just a dot. I suspect that whomever had this before me was trying to solve this problem by replacing every wax paper capacitor in the thing because the internet says so. It didn't work.
Regardless, it has a good CRT and power transformer and other unobtainable items. Hopefully someone can use it. I have no interest in taking it further, I just wanted to see if it worked.

but doesn't work fully.
After a good recap, I'm sure it will get back on track.

Someone tried that already.

Probably some faulty diodes or transistors.

It's a tube unit. Didn't cost but a few dollars, I'm not going to go any further with it. It goes in the donation pile for the Early Television Museum's funds auction.

Aren't those things mildly radioactive?

Not radioactive, but the high-voltage rectifier can, under certain conditions, emit X-Rays.
That's why older television sets had a warning on them, but the dangerous parts were usually enclosed in a metal cage just for that reason. This one is enclosed in a metal cage that is the device itself.

I'm mildly retarded but also handicapped. I don't understand what oscilloscopes do or their purpose. Please explain like I'm slightly above average intelligence but also retarded.

An oscilloscope allows you to see a visual representation of a signal.
For example, you have an amplifier that sounds...off...to you. You connect the oscilloscope to the output and you can visually see the signal coming out. If you know what's going in, you can see if it's changed in some way to make it sound bad to you, and track back through the device to identify where it's happening.
It has other uses in radio and beyond where you can't hear a signal (or it wouldn't make sense if you could) but seeing it allows you to identify and work with it.

Thanks that's the best explanation I've come upon so far.

It can show amplitude and period of a signal (a "waveform"). If you seen a demostration of cardiograms, this is the same thing, but for more broad and refined applications.
It works like a primative television. You have two drivers for its photon gun, which shoots a beam of light against a phosphorus matrix. In stop state, it appears as a dot, and this dot activates the phosphours, causing it to glow. The Y axis is controlled by amplitude of the input signal. A high amplitude will drive the dot upwards and an inverse amplitude will drive it downwards. The X axis is driven by time, which is user configurable. The beam scrolls left to right, then resets like the worlds fastest lawn sprinkler.
If you had connected to a signal that turned on and off every second, you would see two ranks of horizontal colinear alternating dashes spanning left to right.

Slightly. But retarded. And handicapped. Hahah fuck I laughed.
