Hello. I am currently having the following issues with my QN800 65".
Display has a grid of bright spots. Very noticeable on light backgrounds and movement. Changing settings has made no difference.
The second issue is sound. It intermittently has some sort of static/feedback. It seems to be on low base type noise. Confirmed it is the TV speaker as it does not happen when using an external soundbar.
Any information anyone has on these issues, and if they got them resolved would be appreciated.
