I recently received this t.v from a friend, they just had the bulb replace but the problem persist. When i turn on the T.v it will go threw the warm up phase but after 30seconds it turns off with the 3 lights flashing ( temp,lamp and timer)
before, it would stay on after acouple try's but now this is all i get.
I have the same exact TV and had the same exact problem a few years ago. The bad news is the issue is much bigger than the bulb.
At first, the tech thought it was the power supply, but I had to have the engine replaced (also had the bulb replaced at the same time). Lucky for me it was still under the extended warranty that I purchased. The cost of the repairs was $850, and that was in 2007.
The good news is, since I replaced the bulb and engine in 2007, the TV has worked perfectly!
