After i replaced my iPhone 5 display, bought from ebay, my screen is flickering. I´ve used the ifixit pro tool kit, used a ESD wristband and have done the repair exactly as i normally do. I fixed two iPhones at the same time, and both had the problem, but the other iPhone seems to be working as it should now. Any idea on what the problem can be?

The reason for LCD Display flashing screen: shielding coil; Signal interference; Hardware; Refresh frequency setting; Monitor time is too long; Too high frequency; Similar to the frequency of the light source.

LCD display, divided into CCFL backlight and LED backlight two. When the display uses CCFL backlight (that is, usually said LCD display), backlight power off, the lamp will continue to emit light for about a few milliseconds; When the display is backlit with an LED (commonly referred to as an LED backlight display), the characteristics of the LED light allow it to control the speed of switching on and off the power supply more quickly, so there will be no continuous lighting when the power is off. Therefore, the LED backlight flashing screen will be more obvious than the CCFL backlight.

LCD is easily disturbed by a strong electric field or magnetic field, and sometimes the screen jitter is caused by the magnetic field or electric field near the LCD. To liquid crystal display ruled out clean everything around interference, the computer can be moved to an empty table, surrounded by then boot test, if the screen dithering phenomenon disappears, it means that your computer where you found it has a strong electric field or magnetic field interference, please send suspiciously (e.g., speakers of the subwoofer, power transformers, magnetizing cup, etc.) from a computer nearby.

Turn off the LCD and turn it back on a few times to degaussing. (today’s monitors have automatic degaussing when turned on.) LCD screen flashing reason: LCD screen refresh rate problem & display and video card hardware problems display.

In fact, the main reason for the LCD screen dither is the LCD refresh frequency set lower than 75Hz caused by, at this time the screen often appear dither, flicker phenomenon, we only need to put the refresh rate to 75Hz above, then the phenomenon of the screen dither will not appear.

Sometimes because the use of liquid crystal display time is too long, there will be a jitter phenomenon. In order to test whether the electronic components inside the display are old or not, the faulty display can be connected to someone else’s computer for testing. If the fault still disappears, the display is broken and needs to be repaired.

The frequency of the LCD display screen itself is too high, which leads to screen flashing. Generally, there are a few problems in real life that cause screen flashing due to high frequency. People’s naked eyes have no flicker feeling for the picture over 60hz, while the design standard of the general LCD display screen is basically maintained on this data, so the frequency will not be too high under normal circumstances, but at the same time, the screen itself can not be ruled out fault. After the relevant instrument measurement is indeed the fault of the screen itself, in addition to the replacement of a new monochrome LCD screen is the design of equipment-related software.

LCD display and light source frequency close to the situation of the splash screen is very common, because the frequency of the different light source is different, in certain cases, the frequency of the LCD display screen and artificial light similar flicker is also more common, the best way at this time is a kind of artificial light or LCD display equipment, avoid the splash screen.

LCD display, although the price is not high, there are various problems. It will have various effects on our work and life. In ordinary life, when using LCD, as long as pay attention to the following points, will extend the life of LCD.

The phone screen flickering phenomenon on your smartphone is not a very cool experience. For people with sensitive eyesight, it can disturb them and cause eye problems. Having a working display is pretty much linked to the proper use of your smartphone, which is why we are going to show you what to do if your phone screen is flickering or shaking.

Software issues causing flickering in your smartphone is usually as a result of an app needing a higher resolution than what your phone’s GPU can provide. Usually, your smartphone’s Graphics Processing Unit is the component of your smartphone that processes and renders images on your phone.

But there are times that some apps or videos might need a higher resolution, and this is where the problems arise. In times when apps or videos need to be rendered with a higher resolution than what your GPU can provide, the rendering is usually done via an encoder from your Central Processing Unit. Mobile screen flickering then happens when your phone oscillates between using the GPU and the CPU encoder.

Hardware issues with your smartphone that can cause phone screen flickering usually have to do with the LCD panel itself. There could be a faulty connection with the LCD panel itself, or the screen connector could be faulty.

During a video call, the quality of the video is usually dependent on the signal strength of the network. A strong network will mean a near seamless transmission, and both audio and voice capabilities will be fully engaged.

This is the reverse with a bad network. Remember, graphics are rendered via your phone"s GPU. With a bad network, the graphics aren"t exactly "flowing" for your GPU to accurately render them, and this constant breakage is what causes flickering. The only antidote to this problem is to get connected to a faster network.

Doing this can help refresh your phone"s components, especially if the phone is flickering not so seriously. Sometimes, your phone"s processor might have too much to do and transmit to the GPU, and that can also cause phone screen flashing.

Clearing your phone"s cache can also help to stop the phone screen flickering or blinking. Just like an app cache, your phone"s system cache is a storage of data that your phone needs to boot up and work properly.

If data associated with your phone"s GPU is corrupted or isn"t being processed properly, flickering will occur. In this case, clearing the cache will solve the problem.

Once you"ve selected the option, you will get a prompt reconfirming your decision. Once you confirm, the cache is cleared. This decision can"t be overridden.

Booting your smartphone in safe mode is also another option to try and stop phone screen flickering or shaking problem. Take note, booting in safe mode won"t help "cure" the flickering. It is just to help you find out if the screen still flickers or not. If it doesn"t, then it means the flickering is caused by a software glitch.

When your phone screen comes back on, you"ll be prompted to allow your phone boot in safe mode. Tap "OK" and wait for the phone to boot up in safe mode.

In the course of using your phone, if your phone screen is flickering or shaking, then it"s very possible that it"s that application causing the glitching.

Uninstall the application and check your screen"s performance afterward. If it doesn"t flicker, the application was responsible for the shaking. If it does, check out our other fixes.

The flickering of your phone"s screen might also be caused by unexpected bugs in your phone"s brightness settings. The usual culprit is the auto-brightness setting.

But sometimes, there might be a hardware issue or a software glitch resulting from either a recent update or the software being out of date. Either of this will cause flickering and shaking for your screen.

If the phone screen flickering or glitching persists after you"ve tried all the previous fixes, then it"s likely to be a hardware issue that can only be resolved by professionals.

I think the important clue might be that the LCD driver board"s OSD is also subject to these interferences, so it actually shouldn"t be the VGA signal that produces (most) of the noise because in that case the OSD should be unaffected as well!? I"ll see about some makeshift shielding (cardboard box+ aluminium foil?) for the board to test this hypothesis. I guess it could still be both the VGA signal and the board itself...

Could be an issue with the LCD driver or it"s PSU as well. If the caps are failing and the power provided is noisy, it"ll act up. The worse the input signal, the worse it gets. So getting the input signal to be as clean as possible is always a good thing (even if there were no other issues) but if a good quality cable is not fully fixing the problem then chances it"s not the only problem you have. Oh and same goes for video cards but if you can get a stable picture on other displays and not this one then obviously it"s the culprit.

Yeah, the driver board runs off the computer"s PSU and the initial PSU I tested with this setup seemed to produce a lot of visible interference on my CRT even though, cosmetically speaking, the caps look just fine. Anyway, I used a way newer and supposedly decent ATX PSU and the noise cleared up a lot. I replaced the video card for one that was in better shape which reduced noise even further. I"m tempted to say that the signal is now as good as it will get, though I can"t be entirely sure lacking the means (not to mention know how) to make sure the PSU and video card are 100% okay.

I could rule out the PSU by getting a 12v 2a adapter... which I was holding off on because it"s exactly the opposite of what I was trying to do, running the LCD driver board off the PSU
