How to Fix a Phone with a Damaged LCD Screen

Cracked or broken smartphone screens are an unfortunate common occurrence these days. However, with some basic troubleshooting and the right tools, you can often repair minor LCD screen damage on your own without needing complete replacement.

This in-depth guide covers various options to fix phones with cracked or malfunctioning LCD displays, assessing damage levels, temporary fixes, professional repair services, full screen replacement steps and tips to prevent future damage.

Introduction

The LCD (liquid crystal display) screen is one of the most fragile components on modern smartphones. It’s usually made of thin glass and could easily crack or shatter when dropped. Apart from physical cracks, faulty LCD screens can also develop issues like black spots, distorted visuals or flickering displays.

Before replacing the entire LCD screen which can be expensive, it’s worth exploring some quick fixes and workarounds that could potentially save the display. We will cover both temporary solutions as well as full replacement options.

Assessing the Extent of Damage

If your phone took a bad fall or you notice cracked glass or display issues, the first step is to thoroughly assess the type and extent of damage:

Physical Cracks

• Fine cracks in certain areas may just be cosmetic without functionality impact.
• Deep cracks spreading across entire display are more serious.
• Shattered glass with multiple fracture points requires replacement.

Display Functionality

• Check if display still lights up and shows visuals.
• Test touch sensitivity by swiping and tapping on screen.
• Assess if cracks interfere with touch recognition.

Other Components

• Ensure no damage to ports, audio, camera due to cracked body.
• Replace phone chassis if large fragment broken off.

Carefully examining the LCD for physical integrity, pixel issues and touch responsiveness gives an idea whether fixes are available or a screen replacement is needed.

Basic Troubleshooting

Before attempting any repair, first try some software troubleshooting in case the issues are not hardware-related:

Factory Data Reset

Performing a factory reset clears out any software glitches that may be interfering with the display’s normal function.

Check for Software Bugs

Update to latest phone OS version in case a bug is causing problems. Downgrade OS if issues appeared after an update.

Toggle Power Saving

Turn off any battery saver or power saving mode which may limit performance including display functionality.

These basic steps will isolate whether a true LCD hardware problem exists versus a system glitch causing troubles.

Do-It-Yourself Quick Fixes

For minor cracks that have not fully shattered the LCD panel, DIY remedies can temporarily restore visual function:

LCD Screen Filler Kits

Specialty kits allow you to inject liquid filler into cracks to optically hide the damage and smooth out the screen surface.

UV Hardening Resins

Applying UV-based epoxy resins over cracks and curing under a UV lamp can protect existing cracks from worsening.

Tempered Glass Screen Protectors

Affixing tempered glass protectors over the cracked display can hold fragments together and maintain usability.

These quick fixes are temporary but can extend the functioning LCD lifespan in some cases. Ensure no loose glass fragments remain when applying any liquid solution.

Professional Repair Services

For phones with extensive LCD damage or additional issues beyond just cracked glass, professional assistance may be required:

Mail-In Repair Services

Many companies offer a mail-in option where you ship your damaged phone and get it back repaired in a few days.

Local Repair Shops

Visiting an established electronics repair shop to have them assess and fix LCD issues may be more convenient.

Manufacturer Authorized Centers

Official service centers like those run by Apple, Samsung etc. employ OEM parts and specialized technicians.

While costlier than DIY, professional services have the skills, tools and replacement parts to comprehensively repair phone LCD screens and associated components like chassis.

LCD Screen Replacement Process

When the LCD is shattered or has significant display issues that cannot be fixed, a full front glass and display replacement is required:

Procure Replacement Part

Order an OEM or high-quality aftermarket LCD assembly for your specific phone make and model.

Follow Phone Disassembly Guide

Carefully take apart the phone following published teardown instructions for your model.

Transfer Small Components

Attach Replacement Display

Patience and care is needed when handling ribbon cables to avoid any component damage during LCD replacement. Refer to visual guides for your particular phone version.

Preventing Future LCD Damage

Here are some best practices to avoid needing additional LCD repairs:

• Use slim, protective cases and screen shields to absorb impacts. Tempered glass protectors offer the best protection.
• Be mindful to not drop your phone especially on hard surfaces which easily crack glass.
• Do not place heavy objects on top of your phone even when in a case.
