Sony SLV-575UC VCR not loading tapes properly
Hello Everyone about a year ago I purchased at the Goodwill I'm currently working at (I didn't work there when I bought the unit) a Sony Prosumer Grade VHS Player Model SLV-575UC that was working perfectly when I last used it a month ago, but now all the sudden when I went to try and use it tonight to watch some newly acquired NOS Red Skelton Tapes that were still sealed in the original packaging but for some reason the tapes wouldn't play and the Real Time Counter wasn't working and so I took the VCR apart thinking maybe it was a bad belt and sure enough it uses the same toothed belt as the old Sony Betamax VCRs do, and the belt was in excellent condition yet so I buttoned the bottom of the case back up and took it apart and checked the top side with the tape loaded and sure enough only half of the loading mechanism is working, the right side take-up arm works but not the left side one, and the captsan roller arm doesn't engage the tape properly with the capstan pincher/counter wheel assembly. So does anyone on here have any ideas as to why a Sony Prosumer Grade VCR would all of the sudden stop working correctly after only a month of sitting unused? Any help would be appreciated.
Thanks, Levi |

Sounds like the TU load arm gear broke. Look at the botton of the mechanism and see if the gear on picture #1 is cracked or in 2 pieces. (A triangular metal plate has been removed to see the gear in the picture.)
Good luck finding a replacement. Or, the half-load arm is stuck, seized from the old grease. See picture #2. That spring-loaded arm should move freely with your finger. Last edited by Ed in Tx; 03-10-2016 at 09:34 PM. |

I'm kind of curious though how this thing could of started acting up like this in just a little over a month's time, because the last time I used this VCR which was a little over a month ago when me and a friend of mine watched a movie on my LCD Projector in my basement on this VCR, it was working just fine. |

That gear has constant spring tension from a spring that fits inside the gear which eventually causes it to crack or break in two.
The half-load or "pivot" arm as called in the picture can get stuck from just sitting, as the old grease will turn to damn near glue! |

I always used to unplug the connector and ribbon cables shown in the picture still connected, to completely move the board out of the way. btw all pictures I found in minutes by Googling the model number and searching "Images". Very handy. Last edited by Ed in Tx; 03-11-2016 at 12:51 PM. |

OK, I was curious because interestingly enough I saw this same exact VCR in the e-waste pile in the basement of the coffee shop that I used to work for which was a drop-off point for an e-waste center owned and operated by the organization that owned the coffee shop I used to work at. I'm wordering if that VCR I saw in the e-waste pile at the coffee shop I used to work at had the same problem which was why it was broght there by its previous owners.

If that glue holds the plastic gear together with the spring inside the gear under constant pressure like it's supposed to be, I want to know the part number for that glue! Might be handy stuff to have.

Me and a friend fixed a VCR with the same mech and same gear problem. It was an S-VHS deck with 1000 in it's model #. I glued the gear back together with super glue, let it dry for 15 minutes, put it together and it seems to have held up decently. I sold the deck to my friend a few months back after we fixed it, and he has not complained of failure so it seems to have held up.

Good to know super glue will hold that type of plastic. When I did it for a living and charged customers money, and had to guarantee the repair, I never tried gluing a gear. But nowadays you have to improvise.
I did have a few Sonys that developed a loose pressed-on worm gear on the load motor shaft and rather than have an estimate declined to replace a very expensive assembly, I would take the motor out, file a flat spot on the motor shaft, degrease the pulley and shaft and apply a tiny bit of JB Weld. I knew that sucker ain't spinning on the shaft again! |
