Recently returned the 4000IHT since the sound was not very good for the room we have it in. Saturday we upgraded to the 6000 and it seems much better.
The problem we are having is that the sound bar automatically shuts off after 5-10 minutes. Not sure what is causing this and I don't see anything in the manual troubleshooting guide. It did it only several times the first day we used it but today it is doing it constantly.
The other issue is that when the TV is turned off and then later turned on, the sound is so low that we have to turn it up with the Polk remote even though we programmed our Direct TV remote to work with the sound bar. Is there anything we can do to alleviate this? Having to use two remotes is a little bit of an annoyance.
