I have a 46" DLP Samsung That I bought 4 years ago. After the second year the TVs fan would kick on and shut back down constantly. All day and all night everday. About the same time this happened it started making a humming noise when it was on. It needed the bulb replaced. I replaced it with a phillips replacement bulb for $125 which stopped the humming .
Fast forward to 3 weeks ago. The TVs fan still kick on and off on its own and the humming started again. I bought another bulbfor 115 thistime and replaced it again. The humming didnt go away this time and yesterday the TV stopped working all together. It will not cut on.
So I went and bought a 46" LCD Samsung last night and got it set up.
The picture quality in HD was better with my DLP than the LCD I got last night but I am very happy with the new TV.
Im going to hang on to my DLP until I get a couple extra bucks to get it fixed if its possible..After reading online over the past couple days about DLP problems I will never go DLP again...
