Signal Unavailable for my second Set-Top box
I experienced this Signal Unavailable error for the following channels #101, 102, 401-403, 407, 416, 505, 514-516, 708, 812, 817 and 833 on my second Set-Top box. The error message reads "Signal Unavailable - please check that your set-top box is properly connected to the cable point. If the problem persist, please power off and on the set top box from the main power supply."
I have checked the connection and attempted to off and on the Set-Top box several times but to no avail. The rest of the channels are okay, except for channel #427, which is distorted.
My main Set-Top box has no issue though.
Please advise on what can be done. Thanks.
