Samsung NX300 CMOS Sensor Assembly Replacement

Difficulty

Moderate

Steps

Time Required

15 - 25 minutes

Introduction

Given the lack of protection through the lens opening, the elements of the CMOS sensor may be cracked or otherwise damaged during everyday use. The CMOS sensor assembly can be replaced as a whole; or, depending on the circumstances, some of the outer filters and screens can also be replaced with the assistance of this guide.

Tools

Step 1

Using a Phillips #00 precision screwdriver, remove the seven 4mm screws (5 on the bottom of the device and 1 on each of the two sides) holding the back panel to the camera.
On the NX300M model, there is an additional screw under the text AMOLED behind display which should be removed before detaching the back panel of the camera.

Step 2

Using a Phillips #00 precision screwdriver, remove the last 4 mm screw located inside the input ports' compartment.

I've tried this before and I remember this screw not coming off why is this?

Hello Jun. If you are using the correct screwdriver, there may be a few answers to your question:

The camera screw is stuck:

This happened to the team that did this project, just keep working with the screwdriver until it comes loose.

The camera screw lost threads:

If a screw is screwed in incorrectly, it could be permanently lodged in the camera and you will be unable to open it.

The camera screw head is rounded:

If the small pieces of the head (visible) part of the screw are gone with groove marks, the screw is permanently damaged and cannot be removed unless you have special equipment.

Other than these tips, you may need to look elsewhere for more help.

Thank you for the quick reply! Does this have to do with it being the last screw to be taken out? do the screws have to be screwed out in this order? Thank you

There is no order for removing the screws. However, we did take note it was the most difficult to remove because of it's placement. It is difficult to get a grip on the camera when attempting to loosen this screw, therefore it is more prone to damage. Keep trying, but don't force the screw out to where the part may become damaged by means listed in the previous comment.

Step 3

Place a plastic opening tool into the gap between the back panel and camera body, from both the top and the bottom of camera. Carefully pry open the camera and separate the back panel.

Step 4

Using tweezers or your fingers, pull the display's black ribbon from the motherboard. This frees the back panel altogether.
To safely remove ribbons, you would need to first unlock the holding mechanism by lifting up the black strip atop the ribbon adapter.

Hi, I have follow the 4 steps and now my question is about the proper lcd screem. In my case the touch "cristal" is broke do I have to buy all the back side of the camara (with the keys, I mean) o can I take off only the "cristal".

Step 5

Using a Phillips #00 precision screwdriver, remove the three 4mm screws holding the motherboard in place.

Step 6

Using tweezers or a plastic opening tool, release the locks on the ribbon receptors by flicking up the black bars on the holds. Pull the five ribbons away from the motherboard (one hidden from view). This will free the motherboard completely from the device.
To safely remove ribbons, you would need to first unlock the holding mechanism by lifting up the black strip atop the ribbon adapter.

Step 7

The motherboard is now free. Pull the motherboard up and slightly away from the input compartment; it will lift out easily.

Saved my camera! Taking it apart after a fall fixed it!

Step 8

Using a Phillips #00 screwdriver, remove the last 4mm screw attaching the top panel to the rest of the camera.
With the assistance of plastic opening tools, carefully unsnap the top panel, which contains the power switch, out of place.

Step 9

Using a 1.5mm HEX screwdriver, remove the three 5mm black screws located on the extensions of the metal housing assembly.

Just be aware that at this point camera loses its focal lenght. (!!!) That’s why these three screws are sealed with glue after factory adjustment.

Actually after refitting sensor, camera should be taken to some ‘camera service place’ to re-adjust ‘f’

Step 10

With the assistance of tweezers, pull out the last data ribbon connecting the sensor to the sound board. This ribbon must be pulled away from the board that houses the sound speaker.

Step 11

The entire CMOS sensor assembly is now free.
To replace the assembly's low-pass filter, infrared-absorption glass and/or the piezoelectric element only, use a Phillips #00 screwdriver to remove the two 4mm screws on the top and bottom sides of the sensor assembly.

Conclusion

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