Within the first week of receiving the product, the left side of the screen created a black shadow. Upon calling customer support, their response was to reset the default settings. Doing so did not fix the problem. If I turn the TV set off for a few minutes and then turn it on again, the picture will display as expected. The screen continues to create a black shadow at unsuspecting intervals. I have not received satisfactory support from customer service. I feel the TV should be replaced with a new one.
