My unit recently stopped working... I opened it up, checked the fuse and it was blown. Called the store where I purchased it, they told me the warranty was up, to replace the fuse myself. I did, it blew the second fuse. I hate to spend $100+ to get it fixed, only paid $150 for it. But I thought if I could fix it cheap, that would be better than buying another. Does anyone know where to start, or where I can find schematics for it? thanks, Josh
