RCA Selectavision model VKT385 VHS VCR issue

[B 4204 T3]

Quick update, and thanks for all the suggestions.



For the last few days, I have been using my RCA Selectavision VCR, and it's still working well, but I looked online for some new parts for it. I found a company which sells parts for VHS format VCRs, and I ordered some new O-rings, a belt kit, and a tyre kit, just to be safe.



While playing some prerecorded tapes of Hollywood movies, I discovered a bizarre quirk with the VCR, which I've never experienced with any VCR before. When I loaded the tapes & pushed the play button, the VCR started playing the tapes too slowly. The front display was showing the tapes playing at SLP speed, instead of SP speed. A few minutes later, it played the tapes normally, at the SP speed. Another time, it started playing at SLP, but when I pushed the fast forward button to search, it played at SP again.



Does any one know what could be wrong, and has any one else experienced this problem before? I also played the tapes to the very end, and let the VCR rewind automatically, and when it finished rewinding, and I pushed eject, it worked fine, with the tapes completely back in to the cassette.



Thanks again!
