Yes, I still have a HR20-100s, and worked flawlessly for 10+ years. It's been my son's machine for a long time, and he has multiple hard drives of content recorded on it. eSata was not used since these have been non-recoverable for a long time, but it has built in OTA. I'm asking in advance....please don't laugh. It now does not power up, except for the blue power light that flashes. Nothing shows up on the TV screen whatsoever. I'm narrowing down the issue to a bad power supply, but I could be wrong. I'm trying to decipher if it's the power supply or motherboard issue so I need a little assistance.... Every troubleshooting item I tried, I unplugged DVR for 10 seconds then plugged back in..... -I hooked up a Thermal Take external dock, same blue light flashing result. -I took the eSata and power supply cables off the stock drive and tried to power another working hard drive- same result. -I powered up hard drive from a different power source while leaving eSate connected, same result. -I don't have a spare HR20-100 power supply, but I have 13 other power supplies for other different models (Murphy's Law), so that doesn't help me! -I've searched threads back around 2006 to present but cannot fine the specific answers, so hence my post. I'm hoping it is only power supply and not motherboard. I could easily replace it with one of my spare, owned, HR24's sitting on the shelf, but then he loses 4 big hard drives of content. I'm looking for assistance, and also if someone might have a power supply for one of these laying around that I could purchase. Thanks!
