Advertisements Been having this problem, probably for the last 12-18 months with increasing frequency. I'll turn on my TV and find that all of the channels are black (HD, SD, Analog, Digital, all). I don't remember when it started and it used to only happen about once per month now it's as frequent as 1-2 times per week. A soft reboot will restore all of the channels. Things I've tested to try to figure this out: -Hard Reboot (powered off/unplugged all equipment including tuning adapter for extended period or time) -Checked signal strength - I can scan through the channels and it'll show all of the channels at 95-100, however, a picture will not show behind the Signal Strength Meter, just black -Looked in the Cable Card menus and didn't see anything that stood out -Tuning Adapter does not blink an error code -I believe this issue occurred before the tuning adapter -Issue has occurred at 2 different house locations (not related to signal?) The Tivo will show that it is recording (red light/red dot), however it is not really. The green bar does not fill up. The recording history will show "Signal not available." Any ideas on what to check next? Info: Tivo Series 3 (2008), added 2nd hard drive (1 TB), Cox Cable Phoenix, 1 M-Card, Tuning Adapter.
