KLV-40R352E was purchased with a one year warrenty on 11-09-2019. However, when used, the color lines were turned off and the TV turned off. It acted again. When this happens, a black spot has appeared. Sri Lanka Singer says warrenty is now invalid. But they did not test the television. Can't waste $ 470. We still use a 13 year old 29" TV in our home with no repairs.
