Samsung NX300 CMOS Sensor Assembly Replacement

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.

What you need

Step 1 Unscrew the Back Panel
