A relative has a Definitive Technology W Studio sound bar and wireless sub, around 5-6 years old. He replaced his television and can't get the sub to work\/communicate with the sound bar. When he pairs the bar with the sub, the menu says it is paired, but there is a green light on the back of the sub that blinks rather than coming on steady. A Youtube video showing how to connect things seems to suggest there should be a steady green light. The manual doesn't say anything and I am having trouble finding anything online. \n\nDoes anyone know anything about these sound bars and what the green blinking light might mean? Any suggestions for what.to try?
