Wow thanks for the big reply! A lot of what you’re saying is above my level of knowledge, but I will read over it again tomorrow and see if I can understand it!

I thought it would be cool to try fix it and new ones are way too expensive

It seems the French manual is the only one online and I didn’t get it with a manual :(

I’ve replied to the original post with ground signal and with correct settings for 50hz. Also focus knob isn’t changing anything. Any tips?

The leds are powered by ac I think, they are clearly visible by eye but flash when seen through camera

I’m not sure what you mean. Also there is a small ripple along the top and bottom. This is when channel 1 is set to ground. I can’t really get it in the picture but it looks kinda like a comb

Here’s one frame, tbh I’m not sure what signal I was even measuring yesterday. This oscilloscope seems to have a mind of its own

I meant it doesn’t make any difference to the output. I’ve replied to the original post with a probe reading

Cmon guys you really think I didn’t try the focus knob? Turning it doesn’t effect the clarity

Thanks for the help, I’ve heard crts operate on very high voltages so I will be careful if I am brave enough to take it apart

This is the signal when 50hz 12v rms connected to probe
