my TV fell!

    oh lordy lordy am I in trouble. My 32" Sony TV (model KV-27V15 circa
    March 1995) just fell off its TV stand. Stupid me didn't put the
    little belt buckle on at the back so it fell face first on the carpet
    while I was trying to move the unit. The main damage appeard to be a
    HUGE crack in the chassis that goes across the back of the unit and
    across the sides. The crack is large enough that I can open the unit
    up a bit and peek inside -- the picture tube and mainboard LOOKS fine,
    but I'm no repairman so I can't really tell. I think if I put it back
    on its stand as is and ever moved it again it would crack more under
    its own weight. I did plug the unit back in for a second and picture
    looks fine.

    Is this a simple DIY repair job? Think some crazy glue and lots of
    time on my hand I can do this on my own? Or should I bring it in to
    get fixed?

    BTW this is not the main TV unit in the house, but it is an important
    one so if I can get it fixed on the cheap that would be best. Any
    help would be greatly appreciated!

    I would strongly suggest to have the set properly repaired. Crazy glue does
    not go well on circuit boards. It is not rated for going across the traces.
    I have seen cases where it has become conductive, and cause shorts.

    It is possible that there are some traces that are on the verge of being
    cracked, or there may be some options that are not working, that you have
    not checked.

    For safety reasons, the set should be properly checked by someone that is
    experiences, and qualified.

    I have seen sets dropped by movers. These usually have a lot of damage. The
    CRT is also very easily damaged. If the CRT is damaged, one of the most
    common types from being dropped, is that the purity looks like it is off,
    and it is not correctable.

    By-the-way, the KV-27V15 is a 27 inch set, not a 32 inch set!

    Actually I don't think the damage is as bad as I first suspected. I was
    able to unscrew the back panel and it appears that all the damage was
    sustained here. The back panel (which is U shaped covering the back and
    side of the TV set) has split completely in two along the horizontal axis.
    I can see inside and there appears to be no damage to the circuitboard or
    CRT tube *that I can see*, but of course I am NO expert. It's just that
    obviously, nothing seems split in two or anything. So I went to my local
    Home Depot and picked up soem Elmer's ProBond Polyurethane Glue
    (http://www.epinions.com/Glue_Adhesives-Borden_Elmer_s_ProBond_Polyurethane_
    Glue_2_Oz). I'm hoping this might do the job, just glue the two big pieces
    back together then screw the panel back on. Any thoughts?

    On second thought, would be it smarter for me just to order the entire back
    panel from my authorized Sony Service Station? There's one not too far from
    where I live (Toronto, Canada), and I can clearly see the part # for the
    panel (A68KZJ50X). That would avoid all that glue nonsense... :)

    Hi Jason...

    How about a sort-of compromise? Why not invest a
    few minutes calling the largest sony repair depots
    in TO? Ask them if they might not have a not worth
    repair set lying around that you could buy the back
    of, for a few bucks.

    I'm just kinda thinking that sony parts aren't cheap,
    and a used set doesn't particularly need a shiny new
    back, eh? :)

    Take care.

    Good tip Ken about calling the TO sony repair shops. I think I'll do that!

    Jason D: Thanks for pointing out I had the wrong part #! There's a strange
    circle on the inside of the rear panel with a whole bunch of numbers. At
    the top is C1295 ABP, on the left is DOW 6010, and on the right is
    4-043-611. Then there's also a bunch of small squares with some other
    numbers inside them.

    Anyway I think the last series of numbers may be the part # I'm looking for.
    I went to www.partsolver.com and I think the item I'm looking for is:

    Name: CABINET (REAR) ***NLA***
    Part Number: 4-043-661-01

    I'm assuming that only the rear panel for this specific model (KV-27V15)
    will fit?

    Hi...

    Sadly that NLA is going to stand for No Longer Available :(

    Part number you mention is the picture tube number.
    When a Sony is not your main TV it surprises me that price is a concern.
    Back cover might well be over $100Aud.

    Back cover for $100? I pick up 27 inch tv`s at yardsales working perfect in
    great condition for $30 or $40.
     
  10. The back cover may be the least of the problems.

    If there is absolutely no visible damage to the circuit board, carefully
    set it up so you don't have to touch anything and turn it on. If it
    powers up normally with a good picture, it should be fine. THEN worry
    about the back cover. Duct tape, glue, whatever. It's only function
    is to cover the back and maybe support the circuit board. The only
    source for a replacement is likely to be a junk set of the same model
    line.

    However, a fall face down is likely to damage the CRT internally making it not
    worthwhile to repair.

    Make sure to you understand the SAFETY info before doing anything inside!!!

    Glue the panel and use that for a couple of weeks. If no other faults
    become apparent then order a replacement panel

    About 20 years ago our cat knocked an Amstrad 14" portable TV
    (CTV1400) off a shelf. It fell about 4' onto a solid floor and
    completely shattered.

    We bought a complete new case for the set (About $40 in those days)
    swapped the bits over and the set is still going strong today.

    I'm considering that as a viable option. It looks like finding a
    replacement part is proving more difficult than I first thought, as the part
    is no longer available through Sony. So I'm calling various repair shops
    right now to see if they have taht particular set lying around, but as you
    can imagine this isn't so easy.

    Can anyone please recommend me a good glue for plastic parts? Will a $2
    tube of Krazy Glue suffice? Or perhaps hobby glue for model planes? What
    about PVC cement? I'd like this to hold as the TV is rather heavy and the
    back panel is often used for lifting or supporting the unit. Thanks!

    The choice of adhesive depends upon the type of plastic, e.g., PVC, acrylic,
    polycarbonate, etc. In the auto repair business, there are tests that
    involve burning a tiny piece of the plastic to identify it.

    So, first tack might be to carry a shaving to a really good auto body shop
    and let them tell you what it is and what adhesive to use, otherwise...

    ....if, as I'm guessing, strength of the bond is more important to you than
    having it look brand new, then find an inconspicuous spot and test with
    different adhesives to find one that will attack the plastic slightly, and
    use it. Be sure that you're all set to clamp the entire gap together
    before you start applying the adhesive.

    Thanks for the tip. I'm hoping someone might know what the type of plastic
    is for this type of set. Remember it's a 1995 Sony 27" TV. It appears to
    be the same type of soft plastic as the remote, or other parts for this
    unit. If anyone else has any more input on what would be best for the
    plastic used in these sets, I'd greatly appreciate it!

    Also try posting in a few of the toronto.forsale.???
    groups; ask if anyone has a dead set that they'd
    be willing to sell you for parts...

    That is the P/N for the CRT, not the back panel?? Did it break the CRT and
    smash the pc board attached to it??

    Give me the Model and Chassis number of the TV
    I live not to far away and have several good working Chassis,s
    for the Sony TvV,s.

  19. Use duct tape and try the [email protected]#$% thing. You're going obsessive over the
    back panel when there may be terminal damage inside! :)

    Sam, he told us in the original post that it works fine... :)

    His only problem is the broken back, and risks that
    may create.
