i have a mag 37 inch tv model number 37mf437b/37.when turned on the tv tried to display a picture but the screen had black splotches on it and the unit also had popping sounds.after some research i pulled the tv down and noticed on the circuit board that i had 3 blown capacitors,they are the 1000uf 35v variety.after a friend soldered the new ones in,i put it back together and still have the same problem.any ideas what to do next.thanks
