I just want to make sure the threads about this are staying alive until this is fixed. I have a 58" insignia that the sound goes out intermittently. I have a service tech coming to look at it this weekend. Seems to be an extremely common issue but the only resolution I've seen on here so far is to put in an aux cord in the tv every time the sound goes out randomly.... Which just isn't practical given the frequency of the occurrences.
