Query: Faulty power supply, expensive to fix

Sure, this is a great product....until the poorly designed power supply circuit board fails and Samsung will not honor the warranty or fix/recall the part for which this set is infamous industry-wide.(Google "HPT4254" and note the numerous service problems).This manufacturer is riding on the back of its pretty ad campaigns, not its longterm worthiness, durability or other measure of product performance. It's not a minor purchase for most people buying this product; Samsung is not doing a recall on what are necessarily defective components on its power supply board (MOSFETS and capacitors). Avoid.
