Thanks for the link, the TAB fault definitely looks like what I'm experiencing. Not at all what I wanted to hear, but thanks for the information!
On a positive note, I called Samsung and after about 20 minutes on the phone (and being elevated to their "Executive Customer Relations") they agreed to pay for the parts. I'm still looking at roughly $300 in "labor" (I should have been a TV repairman apparently), but needless to say I'm extremely relieved not to be looking at $1000+ for a panel. I thought that since all you generally hear about a given company are negative experiences, I should pass along this positive one. Kudos to Samsung to stepping up to the plate and offering to stand behind their product.
