Philips magnavox 9P6040C104
i just found out why, turn on ur tv and remove back look directly into 3 lenses, if the picture is not nice and clear or looks snowy in all 3 u will not get good color or brightness. I removed my blue tube assembly and took it apart WHILE OUT OF TV. there is cooling fluid between lense and tube, this fluid over time will build a film on the face of the tube and get thick enough to block the tube from projecting picture. (MARK EDGES IT GOES BACK TO GETHERE THE SAME WAY IT CAME APART).Find some new fluid then carefully dissasemble and clean interior of lense, housing and tube thouroughly. Reassemble and fill with new fluid. Do not use old fluid it will be cloudy and snow globe effect. Only do 1 tube at a time this will allow u to realign cross manually as close as possible before u perform convergence. Leave the green for last that is the center and the red and blue are moved to match green. Also be sure to clean mirror and back of screen. Pete
