Testimonial: "good help, this guy knows whats up"
SOURCE: tv is dark
looking on the back of ur tv near the cable input jack there might be an area where u can adjust the brightness on the flyback transformer. if there isn't you will have to remove the back of the tv and adjust it this way. PLEASE DO NOT TOUCH ANYTHING OTHER THAN THE BRIGHTNESS KNOB ON THE FLYBACK, CAUSE YOU MAY BE SHOCKED. so please be careful.
