It's Canada. The law gives no fixed amount of years, only thing said is "reasonable". There's no fixed amount of years. If you paid your TV 200$, they'll probably say that 4 years is reasonable.
But I can personally confirm that LG, Samsung and many other LED tvs are not made to last that much. The LEDs are driven too high and do not have enough thermal dissipation to last more than 10 years. It's wanted by the company. (RCA just makes junk though. They often catch on fire, burn up, etc)
But yeah, we're derailing this. Let's wait for a response...xD
