why did my record player slow down, speed up, then go back to normal?

I actually went to play a record today, and I had to press the (electronic) buttons multiple times before it did its function. There was no speed swell, though.

I am thinking that the buttons are corroded. 
Also, @stereo5 I did the talcum powder thing today. Thanks again for the tip! 

@leemurray2007,


You are quite welcome. 

Because it is not a technics sl-1200 Series.

I put myself through engineering school fixing problems like this. Its very common on older turntables. The speed selector switch can have corrosion, as well as whatever controls might exist for setting the speed on both 33 and 45.
