How to fix or upgrade anything?
Examine the broken or unimproved item carefully. When you find a label or panel that says either”no user serviceable parts inside” or “warranty void if seal is removed” you are getting warmer.
If there is any kind of funny screw, picture of lightning, 11 sided nut or some kind of dare from the FCC on it then you should be sure to know that you are exactly where you want to be.
At some point you should remove the power from the item or device. Don’t forget that a battery is a source of power too. If you have already seen a spark or smelled ozone stop. Always say the box was open when you purchased it.
