You are in a warranty and support issue. That is, if the maker does not answer inside the warranty period then you don't want their products. Some think products are without support, which isn't my experience.
-> That out of the way, there will always be someone on the Internet with a problem involving every product. Nature of the beast.
I have noticed lately that im having problems with HD Matrix Distribution systems on new LG TVs I don't know if anyone else is having a problem and if they are how are you getting them working correctly?
