Mine also has an off brand TV, Jensen. The "surround sound" only worked when playing a DVD. Regular and Sat TV came from the speakers and was barely audible. I added a Vizio 38" 5.1 Sound Bar and now can rattle windows with ease. The built-in sound system is disconnected. The Sony DVD player/surround sound amp ($100 at Wally World) was also dumped for a Blue-Ray player. Now I have good audio both ways. If I could find a good tuner/amp that would fit in the hole I would use it but they don't make one less than abt 19" wide, Grrr. If anyone knows of one let me know.
