Changing the bulb is the best solution, Changing the power consumption settings is only a temporary fix and you should always have a replacement bulb on hand.
Bulb life really depends on how many hours of use it has. If you watch tv more or turn it on and off frequently, bulb life will decrease. That is why people have problems as early as 2 years and some 4 to 5.
Currently I still have my original bulb that came with the TV. I had problems with it in January and its now June. But I do have a new bulb ready.

I had the same exact problem.
I removed the bulb and cleaned it. There is a small screen at the top of the bulb and it was covered with dust. Once it was cleaned I replaced the bulb and it solved the problem.
Thanks to those who posted the solutions

You definitely have a bad lamp. Sony rates the lamp life at between 4000 and 8000 hours. There are 3 things that effect the lamp life, listed in order of importance:
1) number of times the lamp is turned on and off. Every time the lamp is first fired, it takes life off the lamp. Customers I see that turn the TV on in the morning, leave it on all day and then turn it off on the evening can get up to 12000 lamp hours
2) ventilation. Be sure you have at least 6 inches of open space all the way around the set and that the vents are clear of dust and debris.
3) power. If the power is interrupted when the set is on, there cannot be a proper cool down cycle. The fans will run after you turn the set off to properly cool it down, if the power is lost this cannot happen. If your power is unreliable, buy a small UPS to let the set finish a cool down cycle

Occasionally a lamp will faill before the average lamp time due to being defective. from your purchase date it sounds like you got about average lamp time. Be sure to purchase AN ORIGINAL SONY LAMP as a replacement, becuase the aftermarket lamps are bad news, Be sure to rate this solution. Thanks!

This sounds like the ballast for the lamp is going. The ballast sparks the lamp, and if it starts to go, there's not enough current to keep the lamp sparked. Thus it starts to fail: it's the same principle as a fluorescent lamp fixture. Ballasts are available at any service depot, but they're fairly expensive, and perhaps prohibitively so; you may want to look at replacing the monitor itself.
