I r/r the bulb cover, I then removed the burned out bulbs w/ a rag in case they broke they wouldn't have cut my fingers. You turn the bulbs lefty loosy. Installation is just the reverse. Install each bulb and turn righty titey, just snug the bulbs into place. Replace Glass cover and insert one phillips screw in plate and re-tighten
I ordered a new coupler and dropped it into the center hole, jiggled it until it fell into place, put the turntable back on the track, and voila, fixed! It was ridiculously easy.
