    help parts identification for sony kd-55XD9305 CEI

    Hello everyone,
    as indicated in the title i'm trying to identify the "right parts" to fix my sony 55xd9305.
    the issue is already been identified in the motherboard since it seems that the main rom chip deteriorated and the tv can no longer boot (incredible in my opinion but that's it)
    I can get full picture while booting from the usb to try "force" a firmware upgrade but the process stops after some minutes with a sony logo and a blank screen (it's on, i can see backlight).

    So, i was searching for a replacement Motherboard (the memory chip swap is well beyond my skills and no one around me is offering it at a sensible price point) but even if the motherboard is well identified (1-980-833-11 173612611 Y200B590A) i find different opinions regarding the compatibility of other used motherboards with the same codes.
    in particular it seems that the panel model is a foundamental part to be checked to ensure full compatibilty.
    from what i've found around the internet it doesn't seem so, but pretty much all the sellers do indicate the compatibilty only with a specific panel moder number.

    first of all, which one of the one thousands codes i can see on the back of the panel is the one indicating the "panel model number"?
    i can see at least 3 stickers that could somewhat relate to the panel model number (they all report the number "55", so i suppose those are actually related to the panel itself).

    moreover, is the panel model number really that important or can this be "solved" with a pairing?

    thanks in advance to whoever will take its time to try to help me.

    ciao

      Use shopjimmy.com to there put in your model TV and there will be notes as to what board fits what TV, lookup the part number on eBay or wherever you buying and check both on ship jimmy, if all looks good then buy it

          hey eazybone, thanks for the tip.
          i've browsed shopjimmy and they don't mention anything related to motherboard/panel compatibilty issues other than the need to update the firrmware if you get blank screen after the replacement.
          that's more or less what i've found around the internet regarding this topic.

          i've found a MB that "looks good" and it also seems to have been taken out from a tv with the same specs on ebay.
          the seller also accept returns and it seems very legit from the feedbacks so i think i'll give it a try.

          what i'm missing is why a lot of sellers on ebay with the same board insist that the panel must be the same or otherwise it will not work, maybe they don't know the firmware upgrade procedure to pair the components?
          don't know.

          thanks for now

              Basically it's them (sometimes) using a blanket statement that may be true for certain tvs but not others. A way to avoid irresponsible posting since they aren't going to research every board they get. So for SOME tvs yes, but for some no. Likely it's just going to work if shopjimmy lists the same numbers

                  What parts can be salvaged from a plasma with a damaged display panel?
                  by SurrealMustard
                  I recently found myself the proud owner of a later-model Samsung plasma (the PN59D7000 for those keeping score at home) whose panel was, unfortunately, damaged in transport. I'm now preparing to part it out, but am curious as to whether or not any damage would have come to any of the components by attempting to power it up with the panel being broken. I read in one Avsforum thread (for whatever that's worth 😂) that the "scan driver boards" (by which I assume he means buffer boards) could be impacted by doing so. Is that actually the case? If so, since I don't intend on selling bad...

                  Sony Panel Swap Experiment 65x900h with the panel from a 65x930d
                  by r3vsEngIT
                  65x900h with the panel from a 65x930d.

                  900H: model yr 2020, Samsung panel
                  930D: model yr 2016, Innolux panel

                  spec wise the panels are the same. the drivers and tcons are obviously different but what made me want to give this a try is that the wiring diagrams for the data signals going into the tcon for each tv were nearly identical. there are only a couple pins that i am unsure about and that is what brings me here.

                  the 930d has the DPS board where the 900h has none, however, if you follow the pins to the BM1 it would appear that the signals...

                  Bad Panel in Sony Bravia X850G
                  by guidodroid
                  Hello all,
                  I'm trying to understand what is the issue with my 26 months old Sony Bravia KD-65XG8505 (XBR65X850G).
                  It is just few months out of warranty, so Sony doesn't want to do anything, and the local replacement shop also tells me that it's not worth repairing (alhtough this model costed almost 1000 euros just 2 years ago...).

                  Few nights ago the TV started showing some horizontal lines and distorted colors/geometries in the bottom part of the screen (see attached photos).
                  The issue is not as bad as others that I've seen around, but is indeed noticeable...

                  Sony KDL-55W828B Hotspot in LCD panel
                  by PlanB
                  Hello everybody,

                  I need your expertise if my asumption about the failure of this TV is correct.

                  A Sony KDL-55W828B only shows vertical red stripes that vanish to the top when switched on.
                  When only the right side of the LCD is plugged into the T-CON board the right side shows a good image, while the left side is white.
                  When only the left side of the LCD is plugged into the T-CON board the LCD shows a complete white image.

                  I checked some signals on the T-CON board but was not able to find something strange. Then I checked the the caps...
