If you go that route, you have thrown down the gauntlet and support folk run away. I can't guess why folk do that but here goes. Type in that model number in google and then the words jumper cut.
This issue is usually covered by Samsung but 9 out of 10 folk I encounter don't ask Samsung about it. They post on boards or go legal first. Sorry if that upsets you but I hope you can at least try the support methods before you call in the sharks.
Read several comments about the same problem on Samsung. Mine just turned 4 years old, and have spend $1500 for the set, thought they could fix something. Cost more to replace it. Find comments like"...I fixed mine for $10 but no specifics must mean he turned it in for salvage. If everybody is having the same problem, maybe another class action against Samsung is appropriate. Might as well spend the money for a attorney than constant no answer's from Samsung.
