It may have more to do with the joint quality. A cold joint that spikes up has a greater tendency to arc. Using a firestick with no flux is guaranteed to make those types of joints, even with 63/37.

A B&W TV had a sizzling noise and a slightly ragged picture.  With the rear cover off and in a dimly lit room observed a small blue arc into space.  On closer inspection found to be a poor joint in the EHT department with a long solder whisker on the joint.  A quick application of physics and a nail file rounding off the joint and all well again. Yes I did power it down first. ;D

I had a HP 700/96 serial terminal that was making an audible HV noise. Nothing noticeable on the image, though. I took it apart, washed the board with soapy water, let it dry for a few days, and that fixed the noise issue. :)

Because a Windows 8 update was permanently stuck at 95% this Lenovo Z50 Notebook was replaced and about to be tossed. Managed to get my hands on it just in time.
The problem: BIOS was set to UEFI instead of legacy.  :palm: Simply changed that and Bingo!  :phew: It now has a SSD and a new life with Windows 10. After going though the usual Windows 10 motions of course to shut it up a bit. :box:

My simplest "repair" was an oscilloscope (built in 1975) that was used in a university project. When I joined the project they said it had been broken for 2 years and I can have or scrap it. After cleaning and setting it from 110 to 230V I could use it without any problems.
 
Another simple repair was a broken solder joint in a 30 year old audio amplifier .
