Looking up extended warranties for tvs and this may be a dumb question. I don't need any sort of lamp coverage for an LCD, right? Under the impression there is nothing lamp based with an LCD vs my current DLP.

NO need for "lamp coverage" with an LCD.

LEDs are transistors and can fail from heat or power surge like other transistors. They can also age, since the 'white' effect is partially
produced with phosphor in close contact with the hot blue LED. That said, they are extremely reliable in TV applications...

^^^in the context of "lamp coverage" they are not considered to be lamps. "lamp coverage" means coverage for the projection lamps on front or rear projection devices.

There are some LCD TV's that still also use CCFL as a backlight. wink.gif
Either way... no need for "lamp coverage".

I have only witnessed one LCD have its backlight go out, and that was a CCFL Dell monitor that was on constantly for over 8 years.

I'll feel i got my money's worth if the panel lasts at least a decade smile.gif Chances are the tv will be shuffled from one room to another a number of times during that period. One tv gets tossed, another in the household takes its place, so on and so forth. Still have a fully functional 27" panasonic crt, going on 15 years now. Folks don't care/don't want to invest $$$ into a larger hdtv.

My current computer monitor is a dell 30", circa early 2007. Still works well. Also have a sony 19" lcd from 2000 or 2001. Has some issues detecting inputs and returning from standby, but no picture issues.

If you can get a good deal on an extended warranty of 3-4 years, sure, why not. Otherwise, cost of warranty will be similar to that of a single repair visit, give or take.
