Hello. I have a problem with tuning the sound in this tv, because I do not want to insert a parallel sound, and in the tuning menu there is no possibility to choose the DK sound. Interestingly, the module in the TV has a 4.5, 6.0 and 6.5 filter, so it looks like the TV was multi-system. Please suggest or search for a sound on the TV and, if necessary, insert an additional disc.
