went to watch some old movies lately and the betamax deck won't work anymore

Its always been good to me as long as I've had it. It will thread the tape through it fine, the head motor works. But the capstan motor will not run, no play,rewind,FF. I've noticed I can make it work if i press the SLOW button but I haven't tried that with it hooked up to a set to test that.
I've heard about bad caps on these, mine only seems to have one, which does not look bad to me, but I am no expert here.
included is a picture, linked as it is pretty big, any help would be apprechiated!
