We purchased a 70" Sony LCD television about 14 months ago from a business in Carrollton, Ga. While watching, it just went blank. The service tech said it is not repairable, but could not determine the specific problem. They no longer make this model. The frontline customer service reps at Sony can't help you. They have no authorization to do anything. They say someone will call you back in 24-48 hours. We wait several days and no return call. Finally, after 3 weeks Sony customers service told us they will give us a 50% rebate as soon as they had the TV in their possession. Sony said they will handle the shipping of the TV. It's been 2 months and nothing. Does anyone have any helpful suggestions.
