Fisher turntable mc-715 has power but table won't turn. it's able to move manually.
What's likely is that the belt that drives the turntable has snapped. The MC-715 is a mid-late 80's model, so the rubber the belt is made of has had it. A google search for mc-715 belt will turn up a source for a new belt, which you can install fairly easily. There should (though it may be missing) be a hub in center of the platter that you turn to allow playback of 45's. This is removable, simply fit a flathead screwdriver into the side where the raised lines are and pry it away. If it's already missing, then don't worry about it.
You should now see the spindle (silver metal axle/pole that the platter revolves around). At the base of the spindle there will be a black metal circlip. This holds the platter down, and it will have to be removed. Use the flathead screwdriver again to pry it off. You should be able to do this by putting the tip of the screwdriver into one of the two openings on the circlip and using a twisting/prying motion. Once this is off, simply lift the platter off. Remove what's left of the old belt. Even if the old belt is still in one piece, chances are it's too stretched out to be of any use anymore. You will see a track for the belt on the underside of the platter. Put the new belt around this. It will be too loose be a little, but this is to allow for it to stretch and reach the motor spindle (the brass colored spindle off to the right on the now-exposed inner workings.
Along the rim of the underside of the platter you'll see a little plastic peg. Hook the belt onto this. Now, put the platter back on the silver spindle in such a way that the triangular hole where the belt is pulled away from its track by the bit you hooked onto that peg goes over the brass spindle. Once it's down and secure (you may have to wiggle it a little in order for the little gear on the underside to line up correctly) you should turn the platter clockwise. In theory, this should cause the brass spindle to pull the belt off the little peg and onto itself, thus connecting the belt with the drive motor. At this point, move the needle off its stand to see if the belt connected. If not, just repeat the belt-peg-spindle part. It may take a few tries, but it will work sooner or later. After it's turning properly, just replace the circlip that holds the platter down (you'll probably want a pair of pliars to push it on, it's a stiff little thing), and replace the plastic 45 adapter.
