Summary: I purchased my KDL50EX645 directly from SONY for $999. I had it for 15 months (3 months past warranty) and then the power supply board burned out. The TV was completely dead. Since it was 3 month past, SONY would do NOTHING for me. I got the run around for a month just trying to figure out how to get it repaired. Even though it was a defective part, and even thought I spent a grand on their product, they wouldn't offer up any breaks on repair.
Summary: Be warned that most posts are current. I had this TV for 1 year and a few days and it died. Sony calculates the purchase date as the beginning of their warranty period not the actual date that I received the unit. So was so glad that I purchased an extended warranty thru Amazon--that's another issue all together. Called Sony and they wouldn't help since it was a few days past the warranty according to them. For the amount of money spent on this TV is not worth the price.
Summary: This TV quit working a a few days short of one year. Sony has been giving us the run around, now part not available until 12/19. We reported problem on 11/24. Say the offered a replacement and told us this on 26th but we know they did not. They would not have set up an appointment for the serviceman if the part was not going to be available. Don't buy a Sony, ever. I did for 20 years, but would not do it again.
Summary: I would rate model KDL50EX645 less than 1 star if I could. I purchased the KDL50EX645 on Nov. 23, 2012, Black Friday at a SONY store. I have long wanted a SONY TV and I was delighted to have finally purchased one. I gave away an eight year old, 37" Phillips, flat screen TV that was working perfectly. I just wanted a SONY. While the TV did not have as good a picture as expected, I was willing to live with the picture quality because I got what I thought was a good price.
Summary: The tv would not turn back on after 3 months and Amazon would not let me return the item and Sony's customer service is a joke, it's been 3 weeks and they still have not sent me a replacement tv.
Summary: TV dead after 3 months. The only thing that works is a red light that blinks 6 times. I've been waiting ten days for a REFURBISHED replacement, still no TV. SONY customer "service" is non-existent. Stay away from all SONY products.
Summary: I bought a KDL50EX645 on March 31st 2013 and on June 11th 2013 the screen goes black. I called Sony and put in a repair claim that night and they tell me that they are going to order a part and that a service tech will call me in the next 2 business days to set up an appointment to have it fixed.
