Facing TV Problems? Ask a TV Technician.
When you turn the TV off, are you using the power button on the TV, or do you have the set's power cord plugged into a cable box or other device that kills the power to the set when you turn it off?
My point is that if the TV is turned off by simply killing the power to the set, that will dramatically reduce the life of the lamp.
When you turn the set off with the off button on the Mits remote or on the set, it makes the cooling fans continue to run until the lamp cools down. Obviously, if you just kill the power to the set, that doesn't happen.
The only other thing that would shorten the lamp life is if the set is installed in a cabinet where it cannot get sufficient ventillation, or if the vent s are clogged with dust.
Let me know if that answers your question, and thanks for using JustAnswer!
I disagree. The power supply for the lamp really cannot damage the lamp. It will either light the lamp or it won't , it cannot damage the lamp or shorten its life, and I suspect the company you bought the lamp from is trying to weasel out of giving you a new lamp.
All the fans have sensors on them so that if one fails, the set shuts down.
