triplex wall plate problem for controlling Sky via RF out & tv link

["lcomrie" <lancelot@xxxxxxxxxx>]

My electrocoam installed triplex wall outlet plates and the led light
doesn't come on for the tv socket but comes on for the satellite/LNB
socket which is not used.

It seems the triplex plate has a DC feed to the LNB socket and
(obviously) NOT to the UHF socket (because it's fed by only one cable
which can't carry two different voltages simultaneously!)

I've been told to use duplex plates but is there a way to modify the
triplex plates so the 9V DC feed is available on the UHF socket instead.
