Query: Easily the Worst TV Ever!

Bought this in 2003. Within the first year, blew a bulb and required a new optical engine. (The optical engine is the heart if the TV-set and will cost about $2k+). After that it was a new bulb every 9 mo.+, at $300 a lamp. Thank God for the extended service contract!Finally, in 2007 the ballast went out. After two mo.+ no ballast repair/replacement available. Ultimately, and after some haggling, the extended service contract basically refunded the initial purchase price for the TV.I have moved on since. Lesson learned: never another Panasonic TV in my living room...P.S.: Without an extended warranty on a, at that time, $4k purchase, I'd be severly "unhappy". Thank God, the extended warranty came thru all the way!
