1e. Distrust authority.
1f. Ignore all advice.
1g. Test all new replacement components.

2. If at first you don't succeed, destroy any evidence that you even tried!

I never make the same mistake twice. Five or six times is my average.

3. Try Percussive maintenance first. If it works after you bang it, it has
intermitant connections, or components.

Nope. Clean the device first. Depending on the type of filth, that
can be blowing off the dust with compressed air, or washing with a
household cleaner to remove fingerprints, dirt, crud, slime, food,
whatever. Cleaning allows you time to inspect the device, where you
might visually find the problem. Often, the problems go away with the
filth. Customers don't believe that anything has been repaired unless
it's clean.

Instead of beating on the box, try turning it upside down and shaking.
If you hear something rattle around, you've either found the problem,
or what's left of some component. Loose screws and spare parts on new
electronics are amazingly common.
