DW 6000 death tone

[drewdc90]

Hi,
I bought a DW 6000 about a year and a half ago, the thing has be great, hasn't missed a beat but recently it has stopped working. It starts up with a droping tone (sounds like filter res) and doesn't make any sound after that. The keyboard is unresponsive, the editing menu behaves normally and I'm able adjust parameters. I tried changing the battery to a CR2032 with a battery holder for easy replacement but that didn't fix the issue. Patche changes save and work as should but I can't get any sound except the dropping tone on initial fire up. It boots up normally as well. Hope to hear from someone with an idea to what I should do, don't want this board to die after just getting to know it.

Thanks,
Drew.
