Saw someone with a brand new Manhattan S4-R that scans perfectly on setup, then loses BBC1 entirely after sitting in standby for fifteen or twenty minutes. Gone from the guide, 101 comes back as an invalid channel, and the only cure is a full retune. Waiting on the manufacturer to reply, which will take days.
Worth saying to anyone hitting this: a box that loses exactly one channel and recovers after a retune is almost never faulty hardware. Faulty tuners do not do neat work like that. What that pattern usually means is that the receiver rescanned itself while it was idle and grabbed the same channel number from a second, weaker transmitter, then binned the entry when that signal was not stable enough to hold. One channel, one multiplex, one logical channel number in dispute.
So before sending anything back, check signal strength and quality separately in the manual tune screen for the multiplex BBC One sits on, because plenty of installs read a healthy strength while quality falls apart. Strength that is too high is a real failure mode too, especially with a masthead or loft amp in the chain, and an attenuator fixes more of these than people expect. If the box offers any kind of automatic standby retune or overnight update option, switch it off and tune that multiplex manually against your actual local transmitter rather than letting it hunt.
Anyone with this box specifically seen the standby scan misbehave? I would like to know whether this is a firmware thing worth reporting or just the usual aerial story wearing a new badge.
