Noise changes sometimes when I change the channel. If entire back cover, not just lamp cover, is off TV noise will stop. Not sure if color wheel is problem since noise stops with back cover off and noise changes when channels are changed?
After TV is shut off, noise continues until lamp goes off. If I tough lamp area or verticle electrical panel next to lamp I can change the tone of the loud buzzing noise. Noise does not start until about 1 hour after TV is warm..
Fans are quiet. Can't tell if noise is mechanical or electrical but it is transferring through lamp housing and electrical panel near light engine/color wheel area.
