The T7650 is new to me. I retuned my TV after connecting it and my TV will not now scan C31 from Winter Hill to get BBC 4HD, BBC News HD etc. Its to do with the loop through somehow because the TV scans for C31 if I connect the aerial to it directly. Any ideas please, on how to adjust the PVR so that it doesn't block C31 on the TV. Thanks.

The only reason I can think of why this is happening is that the Bush has a UHF modulator on board. Which would be unusual these days.

If it does have one then it should be configurable in the menu system somewhere. Look for an Output Settings or similar menu and see if there is a RF Channel setting option. If such a setting exists and it is currently on something around channel 31 that could be the cause. In which case set it to something like channel 69 which will be well out of the way.

Mind you I would be surprised if that was the reason as PVRs with modulators are pretty rare these days. Verging on the extinct in fact

If you have a decent signal then a simple one in two out passive splitter might be a solution if nothing else works. Just split the aerial feed between Bush and telly.

Did you retune the TV with the T7650 on or off. I'm guessing the latter and with low power standby mode on, this means the majority of the amplification to the loop through is off. Solution is to switch low power mode off (not particularly recommended) or to split the signal beforehand using a cheap passive splitter. If your TV channel is picking most channels up with the T7650 off, then this indicates that you do have a very strong signal which won't suffer if you split it passively (the channels that you mention are on a low power MUX).

The other possibility is that interference from the HDMI cable is knocking out C31, although that would affect the T7650 too - not just the TV, and only when the T7650 is on. I've experienced this with a poor quality HDMI switch (built-in HDMI cable was knocking out C31 completely on all devices). The solution is to reroute cables, keeping HDMI away from aerial cables and the TV's tuner, although ultimately a new HDMI cable may be required.

Yes, it was the latter. Thanks for the advice - got a good quality splitter for less than £2 and all seems well.
