Help with JVC HR-S8000U SuperVHS VCR
Greetings all:
I have owned this VCR since late 1988 but have really only used it during the first 6 years and then it was left just plugged in until using it daily for the past few months. I have only used VHS tapes in the VCR and it still records correctly but there is a problem with playback. What happens is that when Play is pressed, it will show SVHS and then the Digital light for Digital Features comes on and then the Front Panel will display Play and Fast Forward with the tape playing at the Play and Fast Forward speed. Holding down Play button while this occurs will make it play normally and the Digital light will go off but as soon as I lift my finger off the play button, the Play + Fast Forward mode will return. Pressing pause will pause for 1/2 second and then do the Play + Fast Forward mode. I cleaned the tape path including the Audio Control Head and also replaced the idler and idler tire as the idler tire did have a gap but it didn't make a difference even when using a VHS see thru test-jig. Anyone knows what is wrong and will this cost a lot in parts to fix? Will non-JVC authorized servicers be able to fix this? Thanks for any help in advance. Cheers, Vince |

Hi Vincent,
Is there a lot of light getting in through the top/side? these decks have optic sensors and can be tripped into doing strange modes with light otherwise sounds like a faulty switch contact or something similar. when you say play button do you mean on the set or the remote. ~Its possible the remote if someting was spilt into it may do that. if its not related to the remote then there may be a faulty switch on the front panel. its certainly not a common problem. I presume you've unplugged and plugged in again to reset the machine! Other possible causes, dirty mode switch contacts, or poss a capstan motor control fault , but that would be very rare. its more likely to be one of the above. hope this helps AW |

What is weird is that randomly, it will decide to play a tape correctly. As for the play button, I'm talking about the button on the front panel and not the remote as I haven't used my remote in a few years. I've already did the plug/unplug a few times just to make sure that wasn't the problem. I'm just trying to figure out will this be a expensive repair since I see a lot of repairers that aren't factory authorized but don't most problems need a service manual or will equipment tell them what is wrong? Since it seems lots of places have a fixed labor rate but then you have to pay for parts and I hope they don't randomly change out parts. Cheers, Vince |

Sounds to me like the FF button or jog wheel may have a problem. Seen things like this before. Mark Z. "Vincent Poy" wrote in message .154...

P.S. JVC had lots of problems with those blister-switch and flat key-matrix panels in similar models. Mark Z. "Mark D. Zacharias" wrote in message ...

This VCR doesn't have a jog wheel. If if was the FF button then wouldn't
it FF even in the stop position? Cheers, Vince "Mark D. Zacharias" wrote in : Sounds to me like the FF button or jog wheel may have a problem. Seen things like this before. Mark Z.
