Hi, My Tivo S3 TCD 648 with DVR expander started rebooting about once a day and freezing increasing in frequency until now it simply is stuck on Welcome Powering up. Front panel has all lights on and won't Kickstart 54. Tried a new eSATA cable, booting with DVR expander disconnected with same result. After blowing compressed air through the vents with no new result and reading all posts about bulging capacitors, I opened the case and observe no bulging domes. The fan is running but the hard drive doesn't seem to spin up and is silent with no vibration to the touch. Thoughts? Thank you, this forum and site is a great resource!!!
