Hi all! I ask for help from those who know - you need to find out the compatibility of the TV and home theater before buying. Are such requirements possible? (below)
So, what will be needed:
1. TV Samsung PS51E530 ( market.yandex.ru/model.xml?modelid=7960926&hid=90639) must be connected to the LG BH6420P home theater ( market.yandex.ru/model-spec. xml?modelid=8253104&hi... At
the same time, it is necessary that DVB-T digital TV can be watched on the TV
2. The sound of this bundle should be 5.1 - will there be no problems with this?
to plasma, or is it possible somehow through the Home Cinema?
Sorry for the difficult style of presentation, who knows what - write, ok?
