My 600 has black screen again, signal is great 98% on my other receivers, third time in 4 days it needs to be hit again. Why does this keep happening? The 600 doesn't even show the satellite signal at all but my sat finder and other receivers say it has signal. Shaw rebooted it and left on 292 for 10min and it com back. Anyone know why this is happening and what can I do.
A bad cable would mean that the box is getting an intermittent signal. If the signal loss is at the time a security key is rolling you may lose channels. Or the cable is having difficulty with the signal in the frequency range that the channel you are tuning to is coming down the cable from the lnb or switch.
