    • Use a plastic opening tool to release, but NOT remove, the back cover because it is sealed with adhesive.

  12. UYMZNkmSyQr5IqNA

    • Be careful when lifting the cover as you may damage some connections.

    • Slowly lift the cover so that you can disconnect the red and white wires connecting the speaker to the sound card.

  13. ULLZQiETLcSKPdi3

    • Now the back cover should be off and you can access the inside of the casing.

  14. 6JiTuFGREQZDPGFo

    • Remove the black and white wires attached to the wireless card by simply pulling up.

  15. IthR4lrKleBhvjvf

  16. 1pitC3EESdIwXaeb

    • Remove 2 long screws indicated with red circles

    • Remove the remaining screws indicated in blue

    I had two more screws to remove in addition to those shown with the blue circles. One in the lower right corner so that you can remove the 14-pin connector that has a metal guard barely wrapped around the edge of the motherboard, the other is on a rectangular copper pad (and has a black arrow by the screwhead) above one of the blue circles near the lower left corner of the large module below the expansion connector.

    • On the back of the unit, unscrew the three screws surrounding the serial port.

  21. 1NUTLGYArMsiA34p

    • Lift the motherboard as shown, pull towards you and then up.

    • Do not yet try to fully remove the motherboard or you may destroy the connections

    Between the power connector and the back USB port, there's a post through the motherboard just below the #1 Philips screw you removed previously. The motherboard needs to be lifted off that post to get it out.

  22. ZBTHvwDPoGoiE4nN

    • Detach the white ribbon cable, the white cluster connector, and the ribbon cable right next to the cluster

    I also had a 2-pin black connector/cable going to the daughterboard that needed to be removed.

Sur Google, recherchez "DL3UP1396AAA Panasonic CF-29 System Board" (à rechercher sans les guillemets), vous aurez quelques résultats (j'ai vu au moins 2 sites qui la propose à la vente), par contre, elle est cher.

Autre recherche possible : "DL3UP1396BAA Panasonic CF-29 System Board", je ne connais pas la différence entre ces variantes

Autre recherche possible : "DL3U11213FAA Panasonic CF-29 System Board", je ne connais pas la différence entre ces variantes
