According to a Toshiba techie, they estimated
that you loose approximately 2 hours of lamp life everytime you cycle off and on. But their test is far from conclusive as the result's variation is still wide. So they recommend that if you are going to watch TV within the next 2 hours, you are slightly ahead by living it on.
Test on 8,000 hour lamp (under ideal condition):
4 hours a day with 2 on & off cycles = 8 hours/day
base on 350 days a year (there are days in a year that TV is not on) = 2,800 hours even though the actual time that the TV is on is 1,400 hours/year.
If the above is true , then you lamp will last about 3 years with 4,200 hours of actual use (base on 8,000 hour designed lamp life).
If you have left the TV on for the straight 4 hours, then you have used up only 6 hours of lamp life in a day.
At 350 days a year, your lamp will be 2,100 hours old, which leave you about 4 years of designed lamp life, or a total of 5,600 hours of actual use.
I guess that sounds about right for the average joe (assumming my math is correct).
