Chosen Solution
Hello, I’ve replaced screen in my Pixel 2XL and now bottom speaker is not working at all and top one lowers its volume after playing few seconds. Do you have any idea what happened? I was just gently cleaning the speaker grills with Q-Tips soaked in alkohol. Other people had the same issue. https://www.reddit.com/r/GooglePixel/com…
I opened my phone again to find a issue. I knocked out two small components when I was disconnecting bottom display connector. Replacing mainboard is probably the only solution. I think iFixit should add caution information to their teardown guide. According to reddit post even trained workers in repair centers made the same mistake. Here is a photo of broken components https://imgur.com/SZ620sF //EDIT Soldering upper and lower connector as suggested by other users fixed the problem
I had the same problem. I still had the components which was lucky and attempted to resolder them to the board. After many frustrating attempts I noticed that these are not transistors. They are small components the looked like inductors and contained only a few coils. I decided to simply short out connection with solder and this solved the problem. I will add that only one (the lower) of the two had become detached on mine.
It’s definitely caused by one or two resistors/inductors being knocked off during screen replacement, as seen in this picture https://imgur.com/SZ620sF You have to use a fine soldering tip to form a small glob of solder across the knocked off resistor/inductor pads. It’s best to use low heat so that the solder doesn’t flow too easily in order to create a bridge across the pads on the circuit board. Care must be taken, because the molten solder glob can easily short out nearby pads, creating an even bigger issue. It’s not an easy task especially without using a microscope, so those who don’t have the right tools and/or skills, are probably better of taking it to a local phone repair shop and let them bridge the pads for a few bucks. At least now you know exactly what to ask them to do in order to fix your phone. ;)
Did it stop working after you replaced the screen or after you tried cleaning the bottom speaker grill with alcohol? What kind of alcohol did you use? Rubbing Alcohol / Isopropyl Alcohol 90%+ or etc?
Did u managed to repair those or just eeplaced the board or threw the phone away ? I have the same problem and really frustrated on what to do
i have same issue, i knocked out a small black peace down at the bottom speaker when i was replacing my screen, do anyone have a solution to this ? can any google store fix it or the speaker sounds is gone for good !
