I was in a hurry to change it at the time, so I didn’t pay attention to two things.
First, the backlight is relatively close to the axis base, but this does not affect the welding lamp at all.
Second, a backlight capacitor is under the shaft base. However, if this capacitor is not soldered, it will not affect normal use. I have not soldered the backlight capacitor, so it can be used.
If you want to change it, you can change it yourself.
After changing it, it is best to DRC it
