Sky+hd multiroom not working

[RH09]

I have just installed sky+hd as I couldn't get local channels on sky+. The main TV works fine, but the 2 that worked before with cable connections through an amplifier box now don't work.  Sky won't help as they say I should get skyQ which is much more expensive to have on other TVs. Can anyone help please

Is the RF Output Channel of your replacement Sky+HD box set to the same channel as your previous Sky+ box was? If not, you either need to change the RF Output Channel in your Sky box settings or re-tune the TVs to pick up the different channel.
