![]() This is a complicated and delicate process. My belief is that the only reliable way to fix cracked BGA soldering is by removing the IC chip and either replacing it with a new chip or by "reballing" the old chip. Although many people claim these failures can be fixed by "baking" the PC board in an oven, I am not convinced that really works. Sony PS3 and Microsoft Xbox360 are 2 examples of devices which often develop cracked solder with age. This is a common problem with many electronic devices that use "BGA" (ball grid array) type IC chips. Cellular data still works perfectly.īased on my research, both the "fading to black" and the "broken WiFi" issues occur because of broken/cracked solder connections underneath IC chips on the motherboard. Basically I can only use WiFi within 6 feet of an access point. Result: Screen works 100% perfectly and hasn't faded again. Finally I added the paper shim on top of the rear camera connector. I also put some thermal compound on top of the WiFi chip. Nothing appeared visibly broken.įor a temporary fix, I added thermal compound between the main IC chip and the inner front frame. I also had occasional problems with very weak or inoperative WiFi.Īfter reading this thread (and others) I disassembled my G3. Two weeks ago I suddenly began having "screen flickering and fading to black" on my LG G3 D850 (AT&T version). Removing the camera is easy, but if someone wants me to make a video I can do that (if anyone is still looking for solutions). I'll be back in a month to update either way. From what I can see the phone has not run this smooth in a long time, therefore I am going to assume that removing the camera solve the problem. I will update you all in a month to see if the issue has come back. My G3 is unlocked, so I can still use the phone if I were to ever need to have a second phone in the future. So if you have already moved on, and got another phone I would highly suggest messing around with the hardware to see if that solves the problem. The one problem I have run into is that the front facing camera works, however, it produces pictures that are upside down (which I couldnt care about) The other problem is that if this is the solution, you will not be able to take pictures with the rear facing camera. If you're not worried about the warranty, then have a field day.ī. By removing any parts of the phone you automatically void the warranty. What I am saying is that for the first time in many months, I was able to not only get my phone to not flicker but I was also able to get it to remain on consistently. Now, I am not saying that this is the solution to the problem. This time, I just removed the entire rear facing camera. Out of the blue I decided to revisit the camera solution. Then I thought about how many times I dropped the phone, and wondered whether or not the hardware was the problem. At first I attributed the screen flicker to a software update. In my opinion, if you have tried the software route then it is more likely than not a hardware issue. I have heard different accounts, and to a point LG doesn't even know what the cause of the problem is. For others, it could be a software issue. So I suggest staying away from this method unless you don't care about possibly damaging the phoneįor some phones, it could be a hardware issue. I thought about this method, however putting an electronic in the oven does not appear to be the smartest thing to do. However I have seen a few posts on here that have said that rooting does not solve the problem. I attempted to root the phone, and failed miserably. After a few minutes, Not only would the screen flicker but I couldn't get the screen to come back on. I could turn on the phone and get the screen to show up by double tapping. When I finally did factory reset, the problem was still there. This worked for 10 mins and the problem came.Ĭouldn't get the phone to stay on long enough in order to factory reset. There is a video on YT that explains how to do this, but it'll void your warranty. Placing a folded up piece of paper on the camera connector (removing the back and adding pressure to the area where the camera connects to the board). I created this account to tell you all what worked for me, and what didn't work for me.ġ. I ended up getting a new phone, but wasnt happy about trashing a functioning (other than the screen) device. Ive searched for answers and come up short with all suggestions. ![]() ![]() So Ive been struggling with this issue for months. ![]()
