My daughter's 50" 720P Panasonic died one day about 1.5 years ago. It was a no brainer to buy a new set as it was only $150 more than repairing.
However, my Sammy PN58B650 died(pop, burn smell, clicking and blinking red light) and since it cost $2400 in 2009 and probably $1500 to buy a similar new one, the answer isn't as simple. I was just curious as to want others are doing and what were the circumstances? Any help from manufacturers who use these cheap parts.
