There are reports from the USA - several reports - of this situation with Cox set top boxes - people are angry and frustrated - if it's a common problem then it's more likely to be software related than a physical hardware issue.

Its not getting a signal. All you have to do is work out why. Is it tuned correctly? It the aerial plugged in ? Is the cable OK? Is whatever the aerial cable goes to ok? Just think it through
