Get Rid of Wavy Lines On iPad Screen Caused by Moisture

Get Rid of Wavy Lines On iPad Screen Caused by Moisture

August 29, 2018 by Mitch Bartlett 23 Comments

You spent hundreds of dollars on your Apple iPad. It’s your darling device. It’s also a very fragile device. There is a common issue with the device getting moisture trapped inside the screen. This can cause the display screen to produce wavy lines, or dim pixels. In most cases, this problem can be fixed easily with just a few steps.

Personal Backstory

I had a case where an iPad was left in a cold car for an extended period of time. When the device was brought back inside a warm house, a bit of moisture had accumulated the inside of the display. This caused the screen to function much dimmer and produce wavy lines. At times, the iPad would shut off completely. Thankfully, we were able to fix the problem with a little bit of work.


The Fix

1. Shut iPad Off and Let Dry

Since the iPad was a bit wet, we shut it completely off for two days. Hold the Sleep/Wake button until the slider appears, then power it completely off. Also make sure it is not connected to a power source.

Leave it be until it’s completely dry. Otherwise a short may occur and render your iPad useless.


2. Power Up

Once confident enough that enough moisture has dried out, we powered the iPad back on. We still had problems with the screen not displaying properly.


3. Stress the Screen

We cured the lines on the screen by putting the display through a rigorous “stress test”. We do this by going under “Settings” > “Display & Brightness” and slide the brightness slider all the way to the right. Also turn “Auto-Brightness” off.

If you don’t see the “Auto-Brightness” setting under “Display & Brightness“, you can locate this setting under “Settings” > “Accessibility” > “Display“.

Now under “Settings” > “Display & Brightness“, switch “Auto-Lock” to “Never“.


4. Profit

Let the screen remain on and bright for a few hours. In my case, I left it on for an entire day while I worked. The lines eventually worked themselves out of the screen. Once the lines were gone, I switched the Auto-Lock setting back to 2 minutes, and was able to use my iPad as though nothing ever happened to it.

I hope these steps work for you as well as it did for me.

    Woah! Did not know these solutions really works. I have the same case last week and my friend told me to read about this article. Well, it works. Actually, I also going to use a tool he also recommends. This tool is AceThinker iOS System Recovery, he says that this tool works like the solution you mention above.

    I was cooking and an oil olive bottle fell onto the screen, didn’t break the glass but I have huge lines going down from the top 1.5 inches wide and stopping about 3/4 ths of the way. Plus it’s flashing in that area. I’ve put the brightness up all the way and I’ll leave it overnight. I just got this thing fixed from being locked out after an IOS update. Ugh

    I turned off my iPad for 2 days. Once I’ve done it, the screen still displayed static gray lines. I did the second step, but as long as it was on, my iPad screen was having black spaces then. I got scared, so I turned it off again. Is that normal? I really need help please, I have files inside the said gadget.

    Thank you! My kids got an old iPad 2 Mini wet a week ago. There were gray, somewhat static-like lines going across horizontally and the screen was locked on landscape mode. So far, I have done all that you suggested and am waiting for at least one day to pass by while the Brightness is turned all the way up and Auto-Lock is on Never. Already, it seems to be improving. There is now just one black line on the Home screen and it’s not shaking. It seems more stable. I hope it’s better by tomorrow.
