Replace the backlight circuit with a backlight circuit on the old screen. This will solve the problem temporarily.

Part 1: What causes an echo on the phone

1. Design of the mobile phone cause echo when talking on phone

For example, the sound of the earpiece of some mobile phones is too loud, and the sensitivity of the microphone is too high, causing the sound to be returned and causing echo on mobile phone.


Solution:

To test whether your phone is echoing for this reason, the best way is to talk on the headset. If there is no echo when using the headset, the echo is generated from the defective phone design.


2. The network causes an echo on the phone

This is mainly because the transmission of electromagnetic waves reaches your mobile phone in a variety of ways, including various reflected or relayed signals. Since the first path arrives at the strongest signal, the phone will process the priority signal.For the delayed signal that reaches the mobile phone through other paths, the mobile phone will be eliminated by a certain algorithm.

However, sometimes the path of reflection is more, the signal is stronger, and the mobile phone is difficult to eliminate by a fixed algorithm, thus forming echoes in voice calls.


Solution:

If the echo can be successfully eliminated by changing the position of the call during the call, it means that the original multi path route is changed. So, the echo is generated from the network instead of the mobile phone design.


Part 2: How to fix echo on Samsung galaxy s8

You can try the following steps:

1. Restart your phone

How to Fix iPad Screen Flickering Vertical Lines

MY husband’s iPad has flickering lines across the screen.I bought it in December 2015 and he rarely uses it. On a white screen they' re black and on black they're white. I have reset it. Rebooted it and turned the brightness up and auto off.


You are at the right place now. This problem can be caused by the malfunction of a hardware component, unexpected dropping, modifications to the operating system, or errors of the iOS. You can now solve the issue with the three parts below.


[attachimg]13103[/attachimg]


1. Restart your iPad or force a reboot

If this does not work, please restore iPad to factory settings.


How to Hard Restart iPad:

Press the Home button and the Sleep / Wake button for at least ten seconds until you see the Apple logo appear.

After the iPad restarts, you can check again if iPad screen flickering vertical lines.


2. Why are vertical lines appearing on iPad screen

iPad screen has water damaged or dropped may cause iPad display vertical lines.

You can view the iPad external glass, LCD screen, etc. If the external glass breaks; the internal LCD screen may also be damaged.

Generally,if there are colored lines through iPad screen, it is a malfunction on the hardware. There is also a small probability that the problem may be caused by the application.


[attachimg]13104[/attachimg]


For example, vertical lines showing only with iPad camera screen. This is most likely caused by a program. It is recommended that you uninstall the third-party camera program or clear the camera cache.


Check the related hardware cause the iPad screen flickering on and off:

2.1 Check the connection between flexible cable and logic board

First,the screen cable and logic board connections.

If you find dust then clean it with a brush or a little alcohol immediately. If any connection is damaged or the flexible band is bent 90 degrees, it needs to be replaced.

If you check all the options, the next step is to connect the cable to the motherboard and make sure it is connected correctly. Most importantly, do not bend the cable during testing or installation.


2.2 Remove static charge

Poor connection may also be the cause by electrostatic charging. In many cases, when there is a blue line on your iPad screen, a bad connection will occur. It is necessary to use anti-static repair tools when disassembling.


2.3 Check if the screen IC is damaged

Damage to the IC port may also be the cause of the red and blue lines appear on iPad screen.

IC damage can be found by examining the top and left edges of the cable. If the IC is damaged, it must be replaced.


3. How to replace the iPad LCD screen

You must check the root cause of the iPad screen flickering on and off.

The iPad screen may be damaged or not connected properly.


After installing the screen, vertical lines appearing on LCD screen, the fault is with the poor connection made by the ribbon cable. Currently, you need to reinstall the screen.

If dropped iPad screen has lines, you need to replace it.


iPad mini2 as an example for replace the iPad LCD screen:

Preparation tools:

hot guns, crowbar, suction cups, screwdrivers.


1.Heat the screen border with a heat gun

The iPad's screen and body are glued through the frame. We first use a heat gun(which can also use a household hair dryer) to heat the side border of the screen to reduce the stickiness of the border glue.


2.The suction cup lifts the screen border

Then use the suction cup tool to pick up a gap in the screen until the gap is large enough to fit into a crowbar. Next, use the crowbar to expand the gap to prepare for the final opening of the screen.


3.Use crowbars to widen the gap between the screen

Use crowbars to widen the gap between the screen and ensure that the previous gap is not closed until the screen is completely degummed and the screen frame is completely degummed.

Next, we can pick up the screen from the top of the body, and be careful that the cable of bottom and motherboard connections are not broken.


[attachimg]13105[/attachimg]


4. Remove the 4 screws of the LCD display internal screen


[attachimg]13106[/attachimg]


5.Remove the 7 screws on the Isolation aluminum plate.


6.Remove the isolation aluminum plate and remove the 3 screws on the crimping boards.


[attachimg]13107[/attachimg]


7.After seeing the cable, first disconnect the battery cable interface, then remove the internal screen and the external screen socket.

When installing, the opposite is true. The external screen should be installed first, then the internal screen socket should be installed, and finally should be the battery port.


8.Remove the old glue on the perimeter of the outer screen, and attach a new tape around the frame.

Leave no gaps to prevent dust from entering in the future.


Carefully wipe the touch screen dust, fingerprints, etc. with a cloth.

Install the screen back into the iPad, then install the internal screen and insert the battery.

Install the crimping plate, isolate the aluminum plate, and fix the screws on the inside screen.


Turn on and test if there are still vertical lines after iPad screen replacement. Then just reinstall the new screen in the order of disassembly and re-glue the screen frame, thus completing the iPad 2 screen replacement.


The Bottom Line:

The reasons and the solution to fix iPad lines across screen have been found. Here is more troubleshooting about iPad. In addition to the iPad screen, the battery more iPad repair parts you can find at GEMWON.
