Introduction

This guide outlines the steps necessary to replace the circuit board of the camera. Many parts involved in this replacement are delicate, so it is important to be careful in their handling.

    • Unscrew all eight black, 4mm screws with a Philips 000. (The top-most screw shown in the third image can be accessed by lifting the cover flap off.)

    ⚠️ There is a ninth longer screw to unscrew under the flash to undo the case.

    • Pry case open with a metal spludger by slipping the spludger between the back and front case of the camera and wiggling the spludger forwards and backwards.

    • Be careful not to damage the inner components of the camera when slipping the spludger into the camera.

    Painful to see the damage to the upper housing here done by the spudger. Don't do it this way! There is a hidden ninth screw that you can only access when the flash is opened and you look straight into the flash housing. That ninth screw is what's causing the damage in the picture. You MUST unscrew it to be able to remove the back housing without damage!

    Yes, be careful ! I struggled with the case until I found this screw.

    • Carefully unhook the silver strip with tweezers. Get a grasp of the sides of the silver strip with the tweezers, and pull upwards and out.

    • The strip may also be identified by its blue tip, which becomes more visible once pulled out.

Conclusion

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

I was trying to find how to replace the CCD lens sensor on the Nikon Coolpix L840

My camera display will work for a bit, but then goes off. Subsequent efforts to start it yield poor results. If I pick it up and try again in a few hours, I may have a short time to work before the screen goes dark. The batteries are new. I think this might be a case of blown capacitors on board, but I could use insight. The motherboard costs more than the camera now.
