Ok, thanks. I looked at that page, and there's too much information left out for a novice like me to be able to accomplish anything.
I would've thought someone had experienced the same symptoms (powering on but stalling on an illuminated blank screen). I guess I'll just keep an eye on this thread to see if anyone else responds.
Are there any other good troubleshooting resources for these devices? I'm not going to pay Rio $20 so they can just tell me it's dead and give me a coupon for something I don't want.
