Firstly - is there an easy way to disconnect or disable the big - power -on button on the front of the Aventos - I have a very inquisitive 2 yr old that keeps switching the telly off! - Why don't manufactures realise that this can be a problem and put the stanby switch out of sight? Secondly - my Aventos seems to have a yellowish tint on the bottom right of the screen - this can be seen when SKY news has a breaking story with a white background and on the SKY programme menu bar. I can't see it on terrestial TV but maybe it's not so easy to get a white backroung on the screen for long enough? Is this a problem with SKY (i have decent THOR Scarts) or that the new Aventos need degaussing? Thanks for any help!
