I have a TCD652160 which, when I plug it in, the green power light on the front blinks about twice a second. This looks to me like a bad component on the system board that is shorted and causing the power supply to shut down. I swapped in a power supply from another TCD652160 and the behavior is the same. I also removed the CableCARD, unplugged all USB and network connections and even unplugged the drive. The behavior is the same. With the drive connected, I can hear it spin up but I can detect no seeking sounds. There is no video output via component video. The fan does not spin up. There are no signs of damaged/smoked components on the system board and no smoke smell, but I still suspect some component is shorted and shutting down the power supply. Since this is a Lifetime subscribed machine, I'd really like to get it going again. Thoughts?
