iPhone 14 Pro Max: Line on Screen Issue (Purple or Green) – Causes and Repair Solutions

The iPhone 14 Pro Max, a flagship from Apple’s prestigious lineup, has received praise for its stunning Super Retina XDR display and top-tier performance. But despite its advanced engineering, some users are reporting an annoying and sometimes alarming issue — vertical green or purple lines appearing on the screen. If you’re facing this problem, you’re not alone, and thankfully, there are solutions.

In this blog, we’ll break down what causes these colored lines on your iPhone 14 Pro Max display, whether it’s due to impact or water damage, and how iRepair Experts can help bring your device back to life using both aftermarket and genuine quality parts.

Understanding the Green or Purple Line on iPhone 14 Pro Max

One of the standout features of the iPhone 14 Pro Max is its vibrant OLED display, capable of delivering true blacks, high contrast ratios, and vivid colors. However, with great power comes great sensitivity. This advanced display is susceptible to hardware issues — especially after physical trauma or liquid exposure.

What Does the Line Look Like?

Green or Purple Vertical Line: Usually a single straight line running from the top to the bottom of the screen.
Static Line: It doesn’t go away with restarts or software updates.
No Touch Malfunction (Initially): Often, touch functionality remains intact, at least at first, but the line is always visible.

These symptoms suggest a hardware issue — not a software bug.

What Causes This Screen Line Issue?

Although some users initially suspect a software glitch, a persistent colored line on an OLED display typically points to hardware damage. In the iPhone 14 Pro Max, these are the most common culprits:

1. Impact Damage

Dropped your phone recently? Even if your screen didn’t crack, the internal display layers can still suffer damage.

A sharp drop can cause damage to the display connector or disrupt the OLED layers.
The green or purple line appears where the damage occurs — often indicating a column of dead or stuck pixels.

2. Water Damage (Liquid Exposure)

Water and electronics don’t mix — even if your iPhone is advertised as water-resistant.

Liquid can seep into the device through small openings (like the SIM tray, speaker grills, or damaged seals).
Water exposure may short-circuit internal components or corrode the display connector over time.
The green or purple line could develop days or even weeks after the actual exposure.

3. Display Connector Loosening

Sometimes, after an impact, the connector between the logic board and the display can become slightly unseated or damaged.

This could cause intermittent or constant vertical lines.
While rare, it’s still a possibility that an expert repair technician can inspect and address.

Will Apple Cover It Under Warranty?

Unfortunately, Apple’s standard warranty does not cover accidental damage, such as drops or water exposure.

Unless you purchased AppleCare+, which includes limited coverage for accidental damage with a service fee, you’ll likely have to pay for a full screen replacement.
If Apple finds signs of impact or water, they’ll typically charge the full out-of-warranty price, which can be expensive — often over $400-$500.

Your Repair Options: Genuine vs. Aftermarket

If Apple’s pricing is too steep, you have alternatives. That’s where iRepair Experts comes in.
