Black Vertical Lines on LCD assembly after replacement

My supplier from China told me it was from the touch flex cable not being correctly connected. Yes I know you are talking about the LCD. I had the same problem and just made sure the touch was in there perfectly

I had this issue after re-assembly of front screen on an iPhone 5S.

The symptom is light vertical bars that are obvious when screen is bright. In some cases, there may be horizontal bars creating a plaid effect. The screen also does not respond to touch input, making it impossible to shut down, apart from holding sleep and home button. (If the home cable is connected)

I was worried at first that I had damaged the ribbons or pins on the pins on the three connectors. However, I found that I just needed to carefully but firmly press down the connection points until they were solid. I believe the top most connector is the digitizer, which is the easiest one to come lightly unseated while the screen is detached.

I had the effect happen twice during the rear-facing lens cleaning run I was doing and was able to fix it both times.

I think I found a solution.. I took my 5S apart again and I reseated the connectors plus I didn't refit the cable cover plate and voila problem solved.. I've had 2 do this to me so I'll try the other one later on and see if it works or I got lucky.. Worth a try for you though

I had the same problem. I removed the screen in order to swap the battery in an iPhone 5s. When I put the screen back I had black lines running down the picture.

I tried removing and re-inserting the cables but it did not help. I then used a small amount of Electrical Contact Cleaner made by Silver Hook on the connectors on the board and on the screen connectors and then blasted them with compressed air.

Reconnected all the cables and all was well again.

Note: Make sure the phone is off when appying the cleaning fluid and when plugging in or out the cables.

Hope this helps

I never go above 90 degrees and i still get the lines...My supplier told me it was static......but i think its related to the digitizer flex cable connector not being installed on board poperly....It has to click in place on board......and a lot of times it doesnt..... you cannot tell if its on or not sometimes......and i think this may have something to do with it.....i could be wrong........It could just be the flex cable......

Ive had this problem before, but this was with a genuine apple LCD, i just made sure the connectors was correctly in place and they wasnt anything stopping a connect. i also tapped the top right side hand side of the phone, this seemed to fix the problem for me.

I have been refurbishing lcds and have had this problem recently come up with iphones. It could be a couple issues. Either your connectors are not properly seated or a static charge has built. This static charge occurs when seperating the lcd from the glass. There is a white line of special paste at the top of the lcd that prevents static. This gets damaged during the process. If not reapplied it will allow the lcd and even the entire phone to build a static charge.

it worked for me...left the connector cap open inside

The digitizer cause this.You have to be careful connecting the connectors and the reason you have lines and bad touch is because the digitizer connector is loose-meaning you didn't plug it in correctly or you pressed to hard and damaged the pins like you said.srry bud.

Hey guys,

I work at quite a big repair company. We have done thousands of Iphone and Androids.

We have a lot of different supplyers. The latest batch of iphone 4s LCD's all have this problem. Iphone5/5s/6(+)/6s(+) are all fine. We are now testing all the LCD's out of the batch. All have the dark lines. It looks fine at first. But when you get a pop-up or get the shutdown screen, that is when you see the dark lines.

We repair in an ESD space, having ESD wristbands and heelbands. We are testing the lcd's using a disassembled iphone. So this issue (we have here) has nothing to do with the metal plate.

One of the people here said something about static getting in the screen when they get referbrished. But is there any way to get this charge out? Someone told us to put the connectors on the table so it could discharge. But this does exactly nothing. Does anyone have a solution?

And what i found is; White lines mean it's not properly connected or the flex is damaged. This is a different problem then the dark lines i was talking about. Stripes (more then 3) are also a result of a bad connection.

No the line become light in the bacround grey colourful
