If your Samsung Galaxy S8, S8 Plus, Note 8, or S9 has a flickering screen, unresponsive touch, or display glitches, the problem might not be the screen itself—it could be a faulty LCD FPC (Flexible Printed Circuit) connector.
This small but crucial component connects the display flex cable to the motherboard. When damaged or loose, it can cause frustrating display problems.
In this guide, you’ll learn:
✔ How the LCD FPC connector works
✔ Signs it needs replacement
✔ Step-by-step repair instructions
✔ Why a quality replacement matters
Let’s get started!
What Is an LCD FPC Connector Samsung?
The LCD FPC connector is a tiny socket on your phone’s motherboard that secures the display flex cable. It ensures stable communication between the screen and the device’s processor.
Why It Fails:
- Physical damage (dropping the phone)
- Wear and tear from repeated disassembly
- Corrosion from moisture exposure
A damaged connector leads to display malfunctions, but luckily, it’s an affordable fix compared to replacing the entire screen.
Symptoms of a Bad LCD FPC Connector
Watch for these common signs:
1. Flickering or Blank Screen
- Screen flashes on/off randomly
- Goes completely black but phone still works
2. Unresponsive Touchscreen
- Touch inputs lag or don’t register
- Dead zones on the display
3. Distorted Colors or Lines
- Abnormal color tints
- Horizontal/vertical lines on screen
4. Intermittent Display Issues
- Works sometimes, fails others
- Worsens when bending the phone
If you notice these, the FPC connector likely needs replacement.
How to Replace the LCD FPC Connector
Tools You’ll Need:
✔ Precision screwdriver set
✔ Plastic spudger (to avoid scratches)
✔ Tweezers
✔ Replacement LCD FPC connector
✔ Anti-static wrist strap (recommended)
Step-by-Step Guide:
1. Power Off & Disassemble
- Turn off the phone and remove the back glass (S8/S9) or battery (Note 8).
2. Locate the Connector
- Find the small FPC socket near the display flex cable’s connection point.
3. Remove the Old Connector
- Gently lift the locking flap with a spudger.
- Carefully detach the flex cable.
4. Install the New Connector
- Align the new connector precisely.
- Secure it by pressing down the locking flap.
5. Reassemble & Test

Why Choose a High-Quality Replacement Connector?
Not all FPC connectors are equal. A premium replacement ensures:
✅ Secure connection (no loose fittings)
✅ Durable materials (lasts longer)
✅ Perfect compatibility (fits correctly)
Warning: Cheap connectors may break easily or cause further damage.
