    hi all I’m not sure how to say this so here goes when i switch on my Denon 2805 i have noticed that my tv picture would sometimes get brighter or darker or I would get a mark on the bottom left hand side of the screen just like I had a speaker under it which I can see more if the TV is on one of the AUX channels because of the blue background.

    at first I thought this was because I had the amp in a homemade cabinet under the TV so I moved it down 1 shelve and its doing the same thing

    Would this be because the amp and the TV are plugged it the same outlet or do I need to upgrade my power lead cable (I’m using the one which came in the box with the amp )

    Just 1 more thing how much space should you have around you amp for air ?
