My extended warranty on my Samsung PN50c7000 is expiring, and I want to see if I should renew it for 200 bucks or get a brand new tv. I have had 2 in-warranty repairs in the last 6 months, one with 3D not working. Second was the tv not responding to remote. Right now I have no issues, other than my tv goes blank whenever there is a resolution change. I have my pc connected to my tv, and when I watch a video file, it goes black when the video loads, then another blank when I turn it full screen, and a third blank when I close it or minimize it. I don't know how much I will get for this tv, but all the internal parts were replaced in the last repair. Can I sell it as refurbished?
