My setup:

Sony Bravia KDL40CX520 TV
MagicTV 3600
Sony BDV0-E2100 home theatre

I've got the aerial coming in from the wall and going into the MagicTV's aerial in. Then another cable from the MagicTV aerial out into the TV aerial in (i.e. they're daisy chained).

There's also HDMI cables between the MagicTV to the TV, and from the home theatre to the TV.

If I'm watching the TV (straight TV, not via MagicTV box) with the home theatre off then I can get all channels. If I turn the home theatre on then I lose Prime and Choice (all other channels work) and the TV reports "No signal".

Watching TV via the MagicTV box lets me see all channels with both the home theatre on and off.

Why would the home theatre interfere with Prime?

because HDMI is a very noisy signal, and you probably have both HDMI and coax cables with borderline useless shielding in them.

Interesting. That gives me something to look into. This problem has only just started happening, used to work fine.

Rearranging the cables slightly caused the problem to go away, so it looks like it was indeed interference. Damn those cheap Warehouse cables!

Remember, there's no difference between cables, unless there is.

Cheap cables often are just that cheaply made with sub standard materials but mega expensive cables are a rip off simple as that at the standard 1.5mtr length there is no difference in signal quality between a $30 HDMI cable or an $150 dollar one same goes for cheap thin aerial cables cut one open and you'll find no shielding try using a name brand cable like Pudney or the like
