Sounds like you need to replace the lamp. The owners manual should show you how to replace the lamp. You can order the lamp through Sony on their website. Good Luck

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
