It sounds like either bad input connections or a dead box. Are you using a cable box? Did you reboot it? Can you get a picture if you hook the cable directly to the tv? How do you have the input connected?
No. "bad" does not have to mean "dead"PabstinKansas said:If the fan runs when the unit is turned on, doesn't that tell me the power supply is working?
Download the drive manufacturer's diagnostic tools from their website and test the drive.How can I test the hard drive to see if it is working. I am a NOVICE!!!
Are you saying that when you hook the cable box directly to the tv that you are not getting a picture/sound also? If that is the case, why are you trying to diagnose the tivo. Sounds like a signal source or cable box issue.PabstinKansas said:I am using a cable box, and have tried hooking directly to the tv with no success.
