White Vertical Lines on the screen

I have the same vertical lines issue. The way I found is this: make sure brightness is not low (let's say around 75% of the maximum). When stripes appear keep using or keep active your iPad screen for at least 5 minutes. Not less! Then turn off and on the iPad once quite quickly. Lines will disappear and will stay away until your iPad is on. If they are back again that means or your brightness is too low or you didn’t wait 5 minutes. I don’t know why it happens but it sounds like a kind of “screen warm up”. Remember that everytime you switch off the screen then stripes will show up again And you have to repeat steps above

one problem may be the lcd or lcd connecter so you should probably. replace the lcd

I notice that with my iPad it is an intermittent fault. It goes away when I put it to sleep with the button but not if I close its magnetic case.

Wouldn’t an LCD fault be there all the time?

Would the magnetic flap on the case do anything?

I have seen this problem all over the web without a verified answer, which usually means we don’t know.

Interesting.

This might sound stupid but when I had this issue, I would slap the back of my iPad a few times and turn it back on and it would work.

I found about the same thing. Once the lines disappear by turning it off and on again, sometimes several times until lines disappear, plug in the power supply and leave it on. If ines come back, back off and on again. Have worked all day with no lines.

Mine tends to get overall white washed out with lines when it is in a cool (<65°F) temp. I watch often in my garage at night at it happens a lot. On and off will fix temporarily.

Put a space heater a few feet behind it or go back in the house (> 72°F) and it works all night.

After months & months of the line/flickering screen problems, to the point of going blind, I moved the brightness cursor full right, turned automatic brightness off, set the auto lock to ‘never’ & bless my soul, lines are gone! As bob is my witness. I left those settings in place for 24hrs & I’m using it as normal. This is an iPad mini 2. I can’t remeber how old it is but it’s been well used.

I have no idea why this is happening but one of my friend face the similar issue. But there is not while line. Just whitewashes the screen. She replaced the LCD and the LCD connector to fix it.

No kidding, you are correct, this really works, I have been doing this for the past 2 years with the only difference being that I slam shut the auto off cover and it never fails to work normally again.

I tried the full brightness trick, didn't work.

Next I tried the 'slap the back' trick. Guess what? IT WORKED! This led me to the conclusion that the problem is probably a cold solder joint or a loose connection somewhere between the screen and the logic board.
