We had a problem with a previous Samsung TV about a week after the warranty expired. They agreed to the repair however and it needed a part replaced. The repair guy said he had many calls about this problem and that Samsung was apparently using up the parts in the hope that most of them would be ok long enough that they were off the hook.
About 8 months later (after moving to the Villages) the same problem happened. I called the local guy... and it turned out to be the same part. He said he had a roomful of Samsung TVs that folks just traded in.
That's what I did. I got an LG and never had a problem since.
