Simple answer IMO, no.
Even with the full coverage of a warranty, hassle pa rin pag masiraan. My TV has 2 modes, "Store Display" and "Home". In "Store Display" mode, full brightness, all energy saving modes are off. In other word, the TV is running at full tilt. Napakainit ng screen and the back panel. This must have some negative effect on the unit, especially when it's in this mode the whole time during store hours (10-12 hours a day on average).
