A huge thank you to each one of you for your messages, thoughts, tips, and advice. Your engagement has been truly inspiring, and I appreciate the fantastic support.
After considering all your insights, I've decided to take the plunge and start by fixing the non-high voltage parts, which I am comfortable with. I'm excited to see where this journey leads. Additionally, I'm planning to at least create a high-voltage probe to measure HV voltages and maybe even try to fix them when I learn more about safely working with HV.
I want to emphasize that this project is purely for fun. I've got a growing interest in making and repairing more complex boards, where an oscilloscope would be incredibly helpful.
Also, by 'calibration,' I simply meant ensuring that the oscilloscope is not displaying completely inaccurate readings. I'm not aiming for anything elaborate (whatever I can do on my own with some inexpensive equipment is completely fine).
Thanks again for being such an awesome community! I'll post an update if I manage to fix anything.
