we can only watch the program that is on the parent tv, whereas prior to v+ we could switch over in all other rooms watching any program
Has the lead between the V+ "RF Out" socket and the "splitter box" been damaged in the course of the changeover? Check that it's a tight fit at both ends and/or try a substitute lead for that section.
Is this splitter box near the main TV or concealed in a loft? In either case, check it continues to receive its mains power.
Viewing of 1-5 was possible on the "child" TVs because Virgin is obligated to insert those stations' as analogue signals in amongst their own digital cable signals. I would've expected those analogue 1-5 signals to still be present at the Virgin wallplate. I suggest you conduct tests to check that's still the case.
Temporarily, unplug the V+ from the Virgin cable wallplate and connect from it directly into a (portable) TV's "Antenna" socket. Can you now view analogue 1-5? If not, select some unused Presets (e.g. "21-25"), enter the manual tuning mode and see if you can find (and store) analogue 1-5 onto those Presets. If they can't be found, then there's no point fiddling with your equipment within the home further - as the signals you need are no longer supplied to the Virgin socket! Ask Virgin if they can be restored.
If you can tune in Presets 21-25 satisfactorily, restore the usual connections at the main TV. Take the newly-tuned TV to a "child" room. Does the problem still exist when those Presets are viewed there? If so, I'm running out of ideas!
A theory is that the strength of the (new) V+'s own RF modulated signal is much stronger than that of the previous STB
and of the analogue 1-5 signals from the wallplate. When the "child" TVs reduce their gain in response to the strong signal produced in the V+, the 1-5 signals are rendered undetectable by the "child" TVs. A method of tackling that would be to pass the signal from the Virgin wallplate thru a "aerial booster" before it enters the V+.
