Bests & Worsts Reviews from Amazon

I'm writing my first review on Amazon about this product - even though I've been a member of this site for years. This is how unhappy I am with this product and the accompanying service/support. The TV was delivered to my house, and plugged into the wall. The box and packaging was not left behind. At first, I was able to connect the TV to my cable box on HDMI1, and it worked fine. However, as soon as I hooked it up to my blu-ray player on HDMI 2 and then HDMI 3, my experience went downhill in a hurry. The signal from the blu ray player would cut out every 2-3 seconds to a black screen, and then back to the player (as though the disk was playing through). I didn't want to think that it was the TV. So I went and bought new HDMI cables and a new blu-ray player. None of these helped. I even tried using another blu-ray player from my house (a different brand) to no avail. I called the Support number, and although the support person was polite, we spent over an hour on the phone together, with her suggesting that the problems were due to everything BUT the TV. Despite trying multiple HDMI inputs, multiple blu ray players (Is the blu ray player you're using 4k? Because this is a 4k TV...), and multiple cords (Are you using hi-def HDMI cables? This is a hi-def TV...), the call finally ended with me being sent to the store to buy ANOTHER hi-def HDMI cable so that I could prove to the support tech that no, the problem is NOT the machinery. (I was even told that I needed to contact the blu-ray player companies because the fault was on their end.) Finally, after spending another hour and a half on the phone with a different technician the following day (who had me unplug the TV and cable box, whose HDMI input was also no longer working, reset the TV to factory settings multiple times, and then finally remoted to confirm, that yes, there really is a problem with the hardware of the device), they agreed to schedule a service technician at their expense to service the TV. (Although I was reminded multiple times that the warranty would be voided by physical damage- I've had this thing less than a week, and paid to have it mounted to the wall. Any and all cord plug-in/out came at their instruction). So by the end of my 2 and a half hour plus time on the phone with Samsung support, I went from one functioning HDMI port to zero. Samsung referred my case to someone local who will service the TV. I called that Service Technician today, and he says he cannot do the job because Samsung will not let him order the parts to make any kind of repairs. So Samsung scheduled service for me with a technician who cannot help me. Now, because there are no other service technicians in the area (besides the guy who Samsung won't let order parts), I'm stuck waiting on their Remote Service Team to see whether they can find someone in the area to service my television. I'm curious as to what their proposed solution will be if they cannot find someone... I swear, if I still had the box, this thing would be on it's way back already!
