    • Place the device so bottom of the camera is facing up .

    • Remove the five black M1.4 X 3.5 Phillips head screws with a Phillips #000 screwdriver.

    • Remove the marked black M1.4 X 3.5 Phillips head screws on the side of the camera with a Phillips #000 screwdriver.

  3. VjcBwCCvZBFpa56X

    • Remove the marked screw with a Phillips #000 screwdriver.

    There is another screw under the “multi” cover that I think has to be removed to remove the button board

    And another screw on the inner left side to remove the left cover

    I struggled for about 3/4hr to get that cover off before finding that screw just after I replaced everything and packed up for the night. I took a photo, but there doesn’t seem to be a way to post it.

    • Use the plastic opening tool to remove the button board.

    The tutorial would have been more useful if the photo had shown HOW to use the plastic opening tool, which side of the tool must be used, and where to put it. Maybe a comment given as an answer could explain it.

    There is an extra screm hidden under the multi/charger-cover! Very important to know.: :)

    • Disconnect the control board data cable with care. Permanent damage may occur to the control board if tools are used to disconnect the data cable. Use your fingers only.

    • Disconnect the control board data cable by wiggling carefully with your fingertips. Set the control board to the side once it is disconnected.

    • Use the plastic opening tool with a prying motion to remove the side cover of the camera.

    • The cover should come off easily but you might hear light snapping or popping.

  7. fIM1emSADlUjnHlx

    • Orient the device so the lens is facing down.

    • Remove the two black M1.4 X 3.5 Phillips head screws using Phillips #000 screwdriver.

  8. RtPtbsHwKAxqYms6

    • Orient the device so the lens is facing down.

    • Remove the black M1.4 X 3.5 Phillips head screw.

    Removing this screw behind the side cover should be done before removing the side cover of the camera, since this screw holds the cover !

    Jean-François Carporzen -

    This screw has to be removed before, in order to remove the left cover. Then to remove the back with the display also two other screws, one on the lef and another on the right side, under the already removed covers have to be removed

    • LCD screen is very fragile. Handle with care. Do not use tools to remove the screen.

    • Remove the ribbon cable connecting LCD display to camera sensor and battery housing.

  10. qLTpZeATuLl1F3Mg

    • Make sure all ribbon cables are unplugged and remove the motherboard.

    • Ribbon wires can be easily damaged.

    Achtung,

    alle Buchsen der Flachbandkabel sind mit einer Verriegelung versehen, diese müssen vorsichtig von hinten zum Kabel hin aufgeklappt werden. Nach dem einstecken des Kabel die Verriegelung wird herunterdrücken, Wird die Verriegelung nicht gelöst wird die Steckbuchse beschädigt sodass die Hauptplatine ausgetauscht werden muss.

    Detlef Dormann -

    Detlev’s warning is important! — Danger! —

    all the ribbon cable sockets are provided with a lock, which must be carefully opened from the rear towards the cable. After inserting the cable, the lock is pressed down. If the lock is not released, the socket will be damaged so that the main board must be replaced.

Conclusion

To reassemble your device, follow these instructions in reverse order.

Hello!

Nice help to open the camera for fixing viewfinder problems: when not switching on, even when FINDER/MONITOR mode on FINDER, there might be a bad contact in the visor connector. It is a snap lock micro connector, open the lock, then carefully remove clean and replace ribbon cable:this may clear the trouble.

But attention: At least on HX9O without V ext. there are some more screws ;-) and niceties

- one in step 3, under the MULTI connector cap

- 3 on different places to remove LCD screen

Also, there is also an antenna , connected to the LCD assembly and lightly glued on the side
