Are you sure it just wasn't the fuse? Usually that makes a pop sound. Try resetting it.
We have a Sony Bravia LCD that we purchased a few years ago. We had to replace the lamp last year. It was about a $100 fix, and it's still working great. We could hear the sound and even change the channel, but not picture. When we got the new lamp we were shocked at how bright the picture was. Apparently it had been dimming over time. We thought the lamp would last longer, but we're glad it was an inexpensive fix.
