I had a Samsung dlp HL-s4676sx given to me. Previous owner said that it needs a new lamp. I plug it in and green led flashes, turn the tv on and all three led's flash and hear clicking from ballast but lamp does not light and no sound. All fans and color wheel works good. Just wondering befor I purchase a lamp if the lamp is dead would it stop the tv from turning completely on hense no audio or is there something else malfunctioning. Thanks
