This document provides detailed, step-by-step instructions for the disassembly of the Dell U2724DE computer monitor. It is intended for service personnel and recycling facilities to safely remove components and recover materials in compliance with environmental regulations.
Tools Required
To perform the disassembly, the following tools are typically required:
- Screwdriver (Phillips head) #1
- Screwdriver (Phillips head) #2
- Penknife
- Soldering iron and absorber
Disassembly Procedures
The disassembly process involves removing the stand, rear cover, and internal boards. Please follow these steps in order:
- Stand Removal: Press the stand release button and lift the stand away from the monitor.
- Rear Cover Removal: Wedge fingers between the rear cover and middle bezel to release the cover. Disconnect the joystick key cable and sensor cable before fully removing the cover.
- Internal Components: Use the specified Phillips screwdrivers to remove screws securing the interface board, power board, TBT board, and USB board. Note that different screw sizes (e.g., M4x11, M3x5, M3x6) and torque values are specified for different components.
- Capacitor Removal: Electrolyte capacitors must be removed from the printed circuit boards using a soldering iron and absorber. Use a knife to carefully cut the glue between the bulk capacitor and the PCB before desoldering.
Product Material Information
The monitor contains components that must be disposed of or recovered separately in compliance with EU Council Directive 75/442/EEC. This includes printed circuit boards larger than 10 square cm, LCD displays larger than 100 cm2, and electrolyte capacitors larger than 25mm in height and diameter.

Common problems
Difficulty removing the rear cover
Ensure you are wedging fingers between the rear cover and middle bezel at the top corners, then use one hand to press the middle bezel while pulling the rear cover carefully.
Removing bulk capacitors
Cut the glue between the capacitor and PCB with a knife first, ensuring the cutting path does not touch the capacitor or PCB, then use a soldering iron and absorber to remove the pin solder.
Before use
- Ensure you have a Phillips head screwdriver #1 and #2.
- Have a penknife ready for glue removal.
- Prepare a soldering iron and absorber for capacitor removal.
- Work on a clean, protective surface to avoid damaging the panel.
