Hello,new here. 
I bought the Q80t 49" around 4 weeks ago & am having some sound problems. I tried boosting the equaliser 1khz band to try and make dialogue easier to hear, but adjusting any of the equaliser bands seems to have no effect on the sound......in fact, boosting all of the bands to max has no effect on the sound & cutting all bands to zero has no effect. It gives the impression that the equaliser has not been connected! Also, the volume is up and down all the time.
Any help appreciated.
