Hello again, before I start my tv model number is an alba, LCD32880hdf. I have three settings that I'm unsure I should use. Thes are AVL, EFFECT, and an equaliser. Should these settings be on or off, what I'm thinking is that turning them all off you will hear what your meant to hear. To be honest I don't think I should mess with the equaliser, but I'll ask just to be sure.
