My HP 42 incher died after 2.5 years.

HP doesn't make the price for the main board for your TV available on their website, so you'd have to contact them to get an idea of the cost. Likely it will cost at least $300 but could cost a lot more. If you've had the set for 2.5 years, you'll want to ask yourself if you want to put $300 to $600 or more into the repair of an out of warranty TV when you can purchase a new 42" Viore LCD that's 1080p from walmart.com for $578. Their 32" of the same brand is $349. They have other more popular and more expensive brands as well, but the point is what you'll spend to repair your TV would buy one that is brand new with a fresh warranty. And keep in mind that Wal-Mart's extended 2 yr service plan costs less than $100.
