I have a 820-3437-B works fine except when adjusting the backlight brightness it jumps from one brightness setting to the next. Its jerky/choppy vs being a smooth transition. I replaced the backlight chip and no change.
Pram reset didnt do anything. its not too noticable but when holding the brighness up or down button its not as smooth as it should be not too much of a problem but just wondering. Its not letting me upload a gif its saying too large its around 3.7MB
