DO NOT buy a Samsung TV if you plan to hook it up to a home AV surround sound receiver, DO NOT! Please go find the many support chat rooms talking about the issue before you buy. If you connect any Samsung TV to a receiver (Yamaha, Pioneer, etc), every time you turn the TV off, the TV will revert back to the TV speakers. You will have to go into settings, EVERY time you turn the TV back on, and set the sound to your receiver if you want a better sound. This has been an issue for 7+ years, Samsung refuses to fix.
