Toshiba VCR restoration help needed - Toterack
Hi all,
I have replaced the belts inside the Toshiba VCR, (it's about 15 yrs old) and got the mechanics working to load and eject the tape. However, it won't play the tape. Makes a noise for four seconds then shuts off. I've been reading around the www to find out what might need attention and so far haven't found out too much. I'm thinking it might be one of the rollers sticking but they all seem to spin nicely. Anybody want to take a stab at this? Comments? Advise? thanks .. |

Try inserting a tape, wait until it loads, then lift up the vcr, hopefully you still have the access plate off, and gently move the largest cog wheel back and forth. This should free up a jammed mechanism and the movie should play. Let the vcr down gently. If you haven't replaced the belts with ones of the same size, this won't work. |

Let the VCR down gently.

Plugged in the tv and picture and sound is good. How did you know how to do that? The mechanism was jammed from all my mucking about I guess. Thanks again. |

With dummy "eviscerated" cassettte in place and pressing play , manually turning supply or takeup spool should keep the deck in play mode .. |

Sometimes the drum bearings seize and one just needs to free up the upper cylinder and run it a while, though I would not trust it long-term. Mark Z. |

JVCs from that time period also had the bad 3.3 uf surface mount capacitor on the cylinder motor board which caused playback problems. If this unit has one, I'd replace it because it will fail sooner or later. Chuck |
