I bought a Samsung Q70T 75" TV online from Samsung. After 1 month we noticed a dark yellowish vertical bar on the left side of the scree, about 14 inches wide. They wouldn't replace TV and said they would have to send a repair crew to my house after the service place received it. They've cancelled the appointment twice so far because the QLED panel is still in transit. My mistake, I should have never bought a Samsung, and should have bought it locally. After several calls to Samsung service, I got nowhere, they insist that the repairmen have to replace the QLED panel, and I couldn't get a replacement. Why not? We consumers don't count? LOL, I gave my perfectly working, but older Sharp 70" away. Never Samsung again.....
