Repairing JVC HR-S3910U S-VHS

    Hello,

    I have a JVC HR-S3910U S-VHS machine which had a problem accepting
    certain tapes. The eject mechanism would make a funny squeeling noise
    i.e. Similar to the sound of wiping a cloth on glass.

    Tried using WD-40 to correct the problem, but now the machine does not
    play any tapes. Instead, it makes a whirring sound ever time I press
    play. (I think I applied a little too much WD-40 in the gear area,
    the two black wheels which drive the tapes)

    Is there a way to clean it, and make it work again? If so, which
    areas should I be looking at?

    Any info. is helpful.
     
  2. I'm just trying to suppress a gag reflex. It's been a long time since I've
    encountered someone who actually thought they could fix something by
    indiscriminately spraying WD-40 in there.
    Back in the day, someone would occasionally bring in a car stereo with WD-40
    literally dripping out of there when you tipped the piece up on it's side.

    At the very least you are going to need to clean the WD of any rubber pieces
    (belts or idlers) and off any drive surfaces which contact them. Even then
    it's likely more WD will migrate back onto those drive surfaces.

    Your original problem may have been nothing more than a bad belt, but at the
    very least you have complicated the issue, perhaps effectively ruining and
    practical hope of repair.

    Sheesh.

    After spraying WD-40 in your VCR (even a tiny amount) you should now throw
    it in the garbage. You have likely destroyed it.

    LOL --- Yes, I think I got carried away with the WD-40, will have to
    be more careful next time, not to do that, but to post here first for
    any advice.

    I got carried away: Will clean the surfaces and belt(s) as
    suggested. Are there any WD-40 removers on the market? :)

    Thanks for the helpful info.

    P.S. I think I was inspired by an article on the web, which showed how
    to fix a DVD player's drive mechanism (FYI, the Panasonic RV-32) using
    WD-40. Thought that WD-40 would be a useful tool -- You guys are
    right, will have to be more careful next time, and post here first for
    any advice :)

    Pure alcohol.
    Avoid methanol (unless you have very good ventilation) because it is toxic,
    vapors toxic and it also absorbed through the skin.

    Avoid 'rubbing alcohol', unless it is pure isopropyl alcohol, because it
    can leave a residue

    You can use 'Ever-clear' (195 proof vodka) [and even drink the part you
    don't use]. :)

    Keep clear of ignition sources while using.

    Cleaned the machine and parts as best I could, but with so many parts,
    looks like it needs to be looked at. <Sigh> Well, first thing,
    first, I am going to chuck the WD-40, and will not use it, ever
    again.

    Second, if it's going to cost me $70 or more to service it (which is
    what I'm being quoted) I could go with a new machine, but with VHS
    being phased out, it is difficult to get a good, four head machine
    that gives true four head play back, the way it is supposed to. For
    example: I had a look at some combo players today, but they did not
    look that great (The housing for a Toshiba VHS/DVD Combo player was
    terrible: It looked like the machine was from the late 80's, the
    design at least. There was also a Samsung combo, looked a little
    better, the button were small, very non descript.)

    VHS has great value: There is a lot of misrepresentation and
    misunderstanding of this fact, and it would be nice if manufacturers
    still supported it, or at least had a high quality option available on
    the market.


    Any suggestions?

    Any suggestions for a high quality machine, or should I just have this
    serviced?

    Thanks for any info.

    It is quite useful, in its proper place.
    Two suggestions:
    1) stop top posting http://www.caliburn.nl/topposting.html

    2) watch the trash bins. I have 'rescued' three VCRs from the trash
    [several TVs, stereos, microwave ovens, vacuum cleaners, computers,
    monitors, a couple of swords, several chairs, a couple of desks, a sewing
    table, a FAX, a couple of typewriters, an answering machine and a couch]
    almost everything rescued was in working condition or was easy to fix.

    Good to see that netiquette is still around, and that the ng
    netiquette is still around. Will bottom post from now on!


    I actually trashed a better model VCR recently, largely because did
    not want to spend the time replacing all the parts (eject mechanism
    was broken) Great, great machine for its time, but since it was mid
    1990's, did not want to have it around anymore, did not go past 1999
    for timer recordings. Great machine though, even hard to find on e-
    bay (A broken version is selling for $5, but not worth it for me)

    Any recommendations on new VHS machines? Particularly one that would
    have good, high quality 4 head play back? Of course, I could always
    get this serviced as well, but is $70+ worth it?

    Thanks. Good manners are always appreciated.
    Electronics should NOT go to landfill. Recycle.
    You need to decide that yourself. My experience shows that most people
    won't spend more than 1/3 the cost of a new unit to repair an old one.

    Why put a water displacer product into a VCR?


    If it slides, use a lubricant like Lubriplate (White Lithium Grease)or
    MolyLube. If it spins , oil it with 3 in 1 or sewing machine oil sparingly.
    Usually only 1 small drop.

    People use WD-40 so incorrectly.

    What we are all tring to say is what drove you to think that a water displacer
    product sprayed willy nilly into an electronics device would benefit you in
    anyway?

    Did someone suggest this to you or did you read it on the internet? If so, let
    us know where the advice came from , like say from a Wikipedia article or the
    like so we can correct the fool.

    The "did not go past 1999" issue can be resolved by using an identical
    year, such as 1990 instead of 2007, 1998 instead of 2009, etc.

    If you can't find a suitable replacement, I'd say yes.

    Get a good, guaranteed, used VCR. New standalone VCRs are few and far
    between, and DVD/VCR combos are, as you said, garbage. Find a repair
    shop that sells good used equipment. But hurry!

    When I opened the VCR, I noticed something very peculiar: The right
    reel has a spring sticking up, then down, in the caterpillar
    position: It does not look broken though.

    When trying to play the machine, the left reel moves, makes a funny
    whirring sound, and then stops: It does not play the tape at all.

    BTW, thanks for the degreaser suggestion, will look into that, but
    where should I actually spray it?


    I was inspired by an article about repairing another unit I had, the
    Panasonic RV-32 DVD player. About a year ago, there was an article up
    on the web, found it via google, which showed, picture by picture, a
    DVD player problem being "fixed" by WD-40. Since it worked for that,
    I thought it would work for the VCR too, will be more careful next
    time.

    there's a limit to how much we can realistically achieve over the
    internet without physically seeing the deck. perhaps a vid on you tube
    may help? in any case, take it for a quote to a few repair places.

    Good suggestions, will follow up...
     
  20. Guest

    Avoid 'rubbing alcohol', unless it is pure isopropyl alcohol,
    because it
    Will get the degreaser as recommended, but until that arrives: Would
    99% Isopropyl Alcohol solution help remove the WD-40 in the interim,
    or would that leave a residue as well?


    BTW: Can anyone recommend a good, original JVC parts supplier? This
    VCR would not accept certain tapes after a while, and would like to
    solve that problem as well, if I can clean out the WD-40 properly.
