Our Samsung TV that needed a service call? Well, turns out it had a power supply issue that, after researching, I discovered was a very common problem. I contacted Samsung and they said they offer a one-time fix, so that saved us probably $200 or so (or the cost of a new TV). It did take like four days for the guy to get here, but he was in and out in like 15 minutes and now our TV works! YAY!
