Our 3121rl came with the all so common Jensen stereo and TV's. We immediately scrapped them all.
I removed the Jensen stereo in the LR and replaced it with a Bose Solo 5 Soundbar. I used luan plywood and 3/4" square wood to make a frame to fill the remainder of the hole left. We replaced the TV with an LG 4K of the same size.
Put a smaller 28" Continu.us TV and another Bose Solo 5 in the bedroom. The smaller TV allowed me to put the Bose in the cabinet under the TV.
Both are connected via optical audio cable (neither Jensen TV had optical output).
The difference in sound and picture is remarkable.
All of the speakers in and out are now non functional.
