Of course I have no evidence that Philips is any worse than other manufacturers, but our 3 year old Philips Ambilight 42" TV died yesterday. Doesn't power up, just has a red blinking light.
Though on the consumer affairs site, it seems like they get a new complaint every day or so with the exact same problem on the same TVs. With Philips not offering to help. And with the repair bill ($500+) costing almost as much as the cost of a new TV.
I contrast that with Bose and Apple who both replaced the headphones I bought from them for free, even after the warranty expired. Though I suppose those headphones were on the order of $100, and the TV on the order of $800, but still.
