The law quoted states a manufacturer cannot invoke a void warrenty for modifications unrelated to the warrenty claim. For example, if I replace the radio in my car, the manufacturer cannot said i voided my warrenty if the engine has problems (unless the modification did damage it).

So I would argue yes, if i disable the radios and something unrelated is damaged, then the warranty is still valid.

No doubt it's a judgment call for the court, but your car radio is farther from the engine then your TV wifi module is from the TV receiver. Your TV is all likely to be on the same DC circuit, maybe even all soldered together on one board.
