ok update got the tv changed ! its not buzzing now, but i have a problem when watching a film tonite on dark scenes i could see what looked like finger marks about 5"on the right side of the screen after the film finished i dusted the screen and noticed them again while watching taken dusted again but its not dust, little strange to explain. i looks like a ripple if i run my finger over the mark it moves (like when u press a lcd display) but as soon as the pressure is off it returns to the same spot? any ideas?
