While putzing around the house today I came upon my GEOSATpro HDVR3500 sitting on a shelf. It died quite a while back hence it's retirement but I figured the weather was against any outdoor work so I decided to open it up and see what I could find. After pulling the board, flipping it over, and examining it with a magnifying glass it turned out there was a bad solder joint on one of the pins. A little touch up with a solder gun and walla, it's alive! The point being, if an STB just quits, don't toss it out without checking those solder joints, you might just save yourself a few bucks. As someone who restores antique radios and electronics I can tell you that bad solder joints are not that uncommon. Worth a look.
