Panasonic VCR AG1980 FO4
This unit has a tape stuck inside. It will power up and then after
about 2 seconds shuts down and displays FO4. Does anyone know what this code means and what is the fix for it? Thanks, Lenny |

Thanks, Lenny Lenny, There is a worm gear that drives the tape mechanism which cracks. Replacing it with the modified part, cleaning the mode switch, and replacing the pinch roller elevator grease should fix it. Chuck |

Do you know what the procedure is for that? Thanks, Lenny |

Do you know what the procedure is for that? Thanks, Lenny Lenny, I hope you don't have to retime the mechanism because it is a real pain. The manual with detailed timing instructions is the "K" mechanism manual. There are no timing instructions in the AG1980 service manual. Since we are both members of the Yahoo tv repair group, you might see if someone there has the manual as a pdf. I have the paper manual at work but I can't take it home and scan it for you because of university policies. Chuck |
