I have purchased a Samsung LED TV from local dealer near my house delivery was done in just 2 days but installation was to be done by Samsung they took 4 days for the same.
sound quality is average but within just two to three month of usage the picture quality begin to decreasing day by day the image started shaking so I called Samsung that took my TV kept for 15 days repaired it works fine.
but in the last month of warranty TV again face same problem I don't think their service is up to the mark they are not willing to help customers their product quality is extremely poor just like there's customer support friends please don't waste your money on Samsung product if you are going to purchase the TV LG and Sony Alpha better than Samsung quality.
