JVC HR-D470U detects and plays EP only

[WCV82]

I had the same problem but just in reverse on a similar JVC model, it would only play SP tapes, either commercially recorded or home recorded, and could not track LP or EP tapes. After 2 deep cleanings it then played all tapes fine. A few months later I did notice that it did have problems tracking tapes that went back and forth between SP and EP (home recording) to the point where it went from fast speed to slow. However, that only occurred on a few tapes from the same batch so I'm thinking it was because of the original recording VCR.
