Now you can get a better quality rig for approximately half of what you paid. You learned the hard way that most of the time, putting down cash up front for an extended warranty, isn't the deal you thought it was.
If you would be willing to switch gears a little, you might look at plasma as an alternative product type. Right now the 50" size is still a bit of a 'sweet spot' for feature set/picture quality/price. They don't produce many 46" plasmas any more since more folks want bigger sizes to compete with more typical LED-LCD offerings. If your viewing area has some amount of light control, plasma might be a good fit for your needs. YMMV, of course. I would look at the Panasonic ST50 for an amazing buy. Look at the VT50 if you could squeeze a 55" HDTV in your setup and spend twice as much, but get absolutely stellar PQ.
Hi, I have a 46" Sharp Aquos that has a crease or crinkle behind the screen. I have an extended warranty however due to the age (5 years) they are only willing to give me a fraction of what I paid for it. Should I be looking at another manufacturer product?
