    Hi Everyone

    I have been having a very strange issue with imac for a while now which noone else seems to have encountered and I'm hoping someone here may have a solution.

    I have a 27" slim imac (late 2012) with bluetooth keyboard & mouse, everytime I turn it on my TV loses its signal and will have extremely broken picture & sound making it unwatchable until the imac is shut off.

    The TV is a Sony Bravia with built in Freeview which is directly wired to the antenna on the roof. I am from the UK so its a digital tv signal.

    I have turned off wifi on the imac but this does not make a difference. If I leave the mac alone the signal quality slightly increases but as soon as I touch the mouse or keyboard it instantly effects the TV, so possibly somethign to do with the bluetooth signal?

    If anyone can help it would be massively appreciated.
