Our 3 year old 50 inch flat screen tv died today. we had audio but no video. brand name is Insignia. A tech from Dish came out and told us there was nothing he could do for it. So I am looking for a replacement. I am not familiar with them enough to know which to buy. So which brand would you look at or bypass. I'm guessing a price of $300 to $400 would be my top range. Yeah I'm cheap.
