This has been getting more and more annoying and seems to happen at least once a day now. All of a sudden I will lose the signal on a channel I'm watching, but am still able to get other channels. On checking the signal status I found that 1 of the inputs is not locked (it can be either one). After reading somewhere that suggested going into the LNB setup menu and changing the settings I tried setting the 2 "ON" options to off and saving the settings. This now works for a while but now I find that the only way to sort the problem is to set these to ON if they're currently OFF, or OFF if they're currently ON. Whatever I do seems to restore the signal to both inputs immediately and for up to a day when the problem happens again so that I have to toggle them to theopposite setting again. I have tried toggling them to OFF, if thats what the cycle demands, saving the settings and exiting then going back in and setting them to ON and saving settings again but that doesn't work. Any change has to be left until the next time it fails. The box is about 14 months old and has never caused problems before. I know it sounds confusing but it's a difficult problem to explain. Any ideas?
