Logged support call for our faulty (under warranty) XR-55A84K, screen very dark and was clicking into vivid mode constantly, whilst the initial call was dealt with by a helpful lady, where we checked all settings and did a reset, she agreed it appeared to be faulty and would log for an engineer to come and repair/replace, I just need to send photos of the tv picture in every screen mode. Now it appears we are in a support loop, the vivid mode issues was fixed when we did the reset, but for a week, they have been sending me emails about how to fix this, this isn't the issue we have a very dark screen! I firmly asked them to stop sending those emails. Those emails stopped and now we are asked to supply screenshots, photos etc again. I feel this is a 'fob off' loop where they want us to give up. I wont, but after only evert buying their TVs, I will never buy again. And now after reading everything on the internet - DO NOT BUY SONY !
