My parents lifi 56" had a bulb replaced about a 2yrs ago. Hoping this thing lasts them a few more years lol. This tv has worked great but the bulb, what a heaping pile of you know what. There was no way they even touched the 20000 hr claimed life on the bulb.
Anyways the repair went smooth, the tech replaced the bulb hassle free, no cost to us. I'm posting here as I am anticipating another bulb failure, the tv has been taking a bit longer to fire up, so I'll be dealing with panasonic again and see how a second repair goes lol. If there is any out of pocket cost this things going in the dumpster where it belongs.
I still don't know how these bulbs are failing as often as they are. The whole selling point, and the reason why I bought this set for my parents, was the claim of excellent bulb life. I know people with 8yr old dlp's still on their original bulb with heavy usage.
