Bests & Worsts Reviews from Amazon

I received the product from UPS around noon with no apparent damage. Immediately followed the installation and setup instructions and when I powered up the TV all that appeared were colored lines. There were also some unusual patterns in various portions of the screen (under the glass). The TV wouldn't provide any setup instructions. I immediately contacted Amazon to return the TV for a replacement. They suggested I first discuss the problem with an "expert" before returning the product, so I asked them to call me. They called back immediately and as I was explaining the problem our call was disconnected. I've not heard back from them. So, I've boxed the unit back up and UPS will pick it up when they deliver the replacement. So far no indication from Amazon as to when I can expect a NEW replacement. I've purchased several Samsung products and have been very happy with them. I will change the overall rating once I receive a new replacement that works. I received a second unit and the box was intact. However, when I turned it on I couldn’t believe I had received a second defective tv. This one had colored lines running down the left side, horizontal lines across the middle, and a black smudge on the upper left corner. I’m done with this model and have requested a refund. I’m now looking to Sony and LG. It appears as though Samsung’s quality control has suffered a setback.
