Bought 42" HP PL4260N Plasma TV from Best Buy in 2007. In Oct 2011, I got the dreaded "Pop" sound, no picture just sound. I contacted HP Customer service, which was a complete waste of time. They knew about the Y sustain boards being faulty and for awhile back in 2007 they were repairing them for free, that stopped in 2009.
Now they no longer care or are willing to help. Customer Service told me to buy the Y sustains board from eBay and install it myself. After researching the problem, it is apparent that all the HP plasma TV's only last for 2/3 years.
It is very costly to repair the TV, because if 1 board has blown, then mostly likely all 3 boards will either be dead or will very likely blow out too.
We paid $1700.00 for this piece of junk. HP used cheap defective parts knowing that the TV would only be good for 3 years. There needs to be a lawsuit, HP no longer makes TV's, I wonder why?
I will never purchase a HP product again. Do yourself a favor and buy the cheapest TV you can get, because all the big names use the same cheap boards / electronics inside which will fail in 3 years. It's guaranteed.
