I've had a 50" Panny plasma for almost 6 years. For various reasons it's on I'd say almost 18 hours a day and I've never had a problem. I have it hooked up to an APC power conditioner with power regulation (we have frequent power outages/brown outs here) so not sure how much that may be helping, but I think the extended warranty is not necessary. If anything's going to go wrong it usually happens within the first year (or first few months), and the factory warranty would cover that. Love my TV by the way, and I'd buy another Panny plasma in a heartbeat.
Has LED caught up to Plasma?
I know that the plasma tv's in the past were always considered to be better than the LED or LCD formats. I'm wondering if this is still the case. With improvements in technology, has the gap narrowed? I bought a 42" Panasonic Plasma over 8 years ago (and yes, it's still working...wished it would have died by now! lol) and am looking to upgrade to a new 55" tv. In all honestly, when I chose plasma back then, I thought the picture quality of both the plasmas and the LED/LCD models were both very good. Even though my plasmas has lasted all these past 8 years, my big concern is that they do heat up quite a bit....where LED's run much cooler. I'm thinking this might translate into a longer life with and LED tv instead of a plasma. What would you buy today if you were buying??? Plasma or LED?
