When I switch on my Q82T it is perfectly bright and then dims massively after around 10 seconds, making it almost too dark to watch. I've played around with every setting I can find but it makes no difference and the TV does this every time I turn it on.
All eco modes, adaptive brightness etc are turned off and I am using the latest firmware (2101).
This is infuriating me, the TV is less than a year old and it has already been repaired twice for a glitch in the LED display and then a backlight failure.
Is there anything I can do to fix this? This seems like a legitimate fault with the device and should warrant a return or replacement right?
