My husband bought two LG 50PM1M tvs from a sports bar that was going out of business. They are from 2007/2008. He hooked them up and they get a nice picture but neither one has sound. He has gone into the menu and set "TV speaker" as "ON." No sound on either one.
He hooked up external speakers to each TV, and still no sound.
Any ideas? Is this something to do with the fact that they were previously in a sports bar with lots of TVs and probably some sort of bar-wide sound system?
Thanks in advance.
