> Right to fix also doesn't cover warranties, as you will loose your warranty when doing it yourself.
The Magnussen-Moss warranty act of 1975 states (IANAL) that a repair cannot void the warranty unless the manufacturer can prove that your repair caused the damage in question.
This is correct. Those "warranty void if broken" stickers are only worth as much as they mislead people into not bothering to push for warranty claims. (and if it's on something that's not a "consumer good")
