I hope someone here can offer some assistance. I have about a 5 year old Uniden SQ590. Since I have a small dish I use the BUD only for Fox News as I live in a high hurricane area (Florida). I can turn on the receiver which only lasts for about 30 seconds, then goes out. Attempts at unplugging it and plugging it in keeps it on for shorter subsequent periods of time. If this was a computer I would replace the power unit, or look at the caps. The caps look fine. In the book "The Home Satellite TV Installation & Troubleshooting Manual" it states that the voltage regulator is overheating. Any advice in where to start looking? Does anyone have schematics for the Uniden SQ590? Thanks in advance.
