Are tv LCD panels interchangeable?

    Hi all,

    Does anyone know if LCD panels for tv's are interchangeable? I have a
    26" Olevia that powers on, but the screen has been busted. I have my
    eye on a Panasonic 26" but would like to know if I'm fighting a losing
    battle.

    Thanks!

    In general - yes. Many manufacturers sell panels to other manufacturers,
    and some brands may really be another brand that has been re-badged.
    chances are your TV may have a panel that was manufactured by a different
    company.
    The problem is that you would need the exact same panel and I don't know of
    any printed or on-line cross reference that will tell you the exact panel
    model numbers that are used in different tvs by different manufacturers.
    The same is true for plasma panels.
    Your only chance would be to open the TV with the broken panel, get an exact
    part number of the panel, then find a TV with an identical panel - which is
    nearly impossible.
    Usually a TV with a broken LCD or plasma panel is only good as a spare-parts
    donor for an identical TV which has a problem that is not directly related
    to the panel.
    Good Luck.

    Thanks for your reply. I want to get a *little* more detailed
    though. I took my TV apart to get a little more intimate with it. I
    think the part your talking about (at least the only part I saw with a
    model number which is 2-3" thick) appears to be in good shape (http://
    img242.imageshack.us/img242/5419/insidesp2.jpg).

    Is the thin panel itself proprietary? Or is there more of a standard
    for how to interface with the rest of the tv? As you can see from
    this image, it's got a tiny crack in it. (http://img397.imageshack.us/
    img397/2707/frontvy3.jpg and http://img394.imageshack.us/img394/5411/backby8.jpg).

    I captured this image from a video for a 46" TV I believe it was
    (http://img394.imageshack.us/img394/2194/insidelcdvideooo6.jpg). To
    my untrained eye, it looks very similar. I'm just curious as to where
    the disconnect is between the thin lcd panel from one 26" tv to
    another.

    Any more thoughts?

    Anyone?

    Thanks!

    I don't know if my last message got through or not... anyway,
    basically I want to make sure we're on the same page. I took the tv
    apart and the only portion I see with a model # is the 2-3" thick bit
    with the flat lcd panel attached (http://img397.imageshack.us/
    img397/2707/frontvy3.jpg).

    I took the flat panel off and it's pretty dinged up as you can see
    (http://img394.imageshack.us/img394/5411/backby8.jpg).

    But I'm curious to know if the very flat panel is proprietary or if
    there is some standard. Here's what I'm looking at (http://
    img397.imageshack.us/img397/2707/frontvy3.jpg).

    I captured this from a video of a 46" tv (http://img394.imageshack.us/
    img394/2194/insidelcdvideooo6.jpg). To me it's very similar (except
    for size of course). But I'm just trying to make sure the explanation
    above wasn't just simplified and that by breaking down the tv to the
    lcd panel, there is no standard and easily interchangeable part.

    Thanks!

    Let me try one last time. I guess the links are screwing things up...

    I appear to be having all sorts of trouble replying. I guess because
    I'm including links.

    Basically I want to make sure we're on the same page. I took the tv
    apart and the only portion I see with a model # is the 2-3" thick bit
    with the flat lcd panel attached.

    I took the very thin lcd panel off and am curious to know if the very
    flat panel is proprietary or if there is some standard.

    I saw a video that took apart a 46" tv and the bottom of the panel,
    where the ribbon cables connect, looks very similar to my untrained
    eye. That is to say, the way the ribbons connect whatever the boards
    on the bottom and side are, are the same. What I want to know is if
    the boards are the same or even if every 26" has the same amount of
    ribbon cables connected to the bottom/side.

    I guess I'm asking, can I take a thin panel, with ribbon cables
    attached and connect it to my preexisting "boards"?

    This post would have made a lot more sense with pictures.

    Thanks!

    The entire screen (including the back light) is replaced as a single
    unit. You would never replace just the LCD glass. There should be a
    make and model on the back of the back light. This is what you need
    to look for. Many of those cheaper brands use the same off brand
    Chinese LCD panels, but finding one with the same LCD will be a shot
    in the dark. A Panasonic will probably have a Japanese, or Korean
    LCD.

    While most LCDs use a similar interface, there are lots of little
    differences that will make substituting virtually impossible. You'll
    run into problems like different mounting holes, different electrical
    connectors, and slight differences in the LCD data. I've even seen
    identical TVs with different, incompatible LCD panels. In one case,
    swapping main boards between two identical TVs with different LCDs
    resulted in the picture being upside down.
