love this tv but, had the tv for several days, no problems. then purchased the samsung hd4k dvd player. was told this remote would do both tv and dvd player. streamed a movie from google movies and the problem with sound started. picture was great but sound was reduced to whisper at 100% volume. this manifested to everything /all sources, cable,dvd, streaming etc. tried for 2 hrs to fix. next day i tried again but this time i used the tv remote. was able to get into way more tv settings than the dvd remote . could not find/fix my problem via audio reset or other settings. finally found a factory reset icon in the settings section and this erased and rebooted everything as if it was just out of the box. now every works again. even though the samsung remotes are very similar they are not universal despite what the salesperson says. oh ya, my wifi code is 15 digits all caps, put a cap lock icon on the sign in screen..pita!
ps. dont forget to download the user manual
