|had these speakers for over a decade with out a problem, when I also started having no sound and HD showed up in the lcd display. Thought it was sound card. After buying new card the same problem showed up. Someone on a post said that the HD was for when the headphone jack was in use. I forgot that the left speaker had a jack built in. I plugged a jack in and out to see if it would correct problem, no luck. So I went into speaker and cut the gray and blue wires from the circuit board in the base (left enough of the wire so I could re-connect just incase). Sound came back and has been working fine for days.|
The wires that I cut where connected to the side that said 1.The other side said 2. I think I got lucky and cut the correct wires the first time.
