But what do you guys recommend for assembly, to make the phones waterproof again?

If i try to adjust using the settings the screen reaches maximum brightness after about 20% of the slider, any slider movement above this makes no change to the bightness of the backlight.

Has anyone come across this before?

p.s. The screen was bought from a vendor on eBay claiming to sell OEM replacement parts. Compared side by side to the original screen that came out of the phone, there were next to no differences in the production quality apart from the original screen had a black paper-like cover on the back of the LCD and the replacement part had a shiny mirror like cover.

I am not a novice and I have fixed Sony devices before and i am just baffled as to what it could be. I have used company before for previous screens but not ruling out faulty screens :/

- Have you guys experienced anything similar?

- And any solution if so..

thanks

Is my phone for sure bricked?

⟐ Comment deleted May 14, 2019 at 9:16 MST

I read there is a fuse that helps fix this issue but I don't know if this will help. Here it is: http://www.mobilerdx.com/2015/03/sony-xp...

It's the first time the phone is opened and I never thouched the fuse because it's underneath a metallic plate, which I didn't even touch or moved. So why would I have to do something with the fuse if I never did anything to it and the screen was working when I tested it?? It just stopped working afterwards for some unknown reason.

The phone is on, because there is the blinking light. So, do you have some suggestions??? Should I actually try to add a jumper on the fuse??

Thanks.

EDIT: I remember that when I was about to close the phone I put the screen upside down, and it was when the screen backlight stopped working. Is this some reason why the fuse could have been damaged???

Thanks

Looking through the strip-down, the microphone is not mentioned, but there is an obvious component visible, which is a discrete component at the end, and looking through the other repairs it doesn't seem to be bonded to the screen like the earpiece.

However, I cannot find a microphone as a replacement component on any of the parts websites. On the full-size Z3 it is part of the main flex, but it's not on the Z3C flex.

Any ideas, folks?

I've recently replaced the screen on my Z3 Compact (I've done this a few times before...) but I think this time I've definitely done something wrong.

Symptoms are as follows:

Phone is on, LCD is working (I can only tell this from the backlight being on) but nothing will boot up. I turn the phone on and I don't get a splash screen or boot up noise.

I've tried resetting it using the power button/volume switch but still get nothing

Any Ideas?

My screen cracked so I decided to replace it. The screen partially worked on the top half, but the bottom half was cracked. I have fixed other phones such as the LG G2 and LG G3, but never a Sony. I followed the instructions in this video.

Sony Xperia Z3 Compact LCD Screen Replacement

I test-fitted my screen before installing the adhesive and when I turned the phone on the screen doesn't light up whatsoever. So I unplugged the new screen and plugged in my old cracked one, that one didn't light up either. I can hear the phone working for example when I push the power button I get a long vibrating noise (startup vibration). I also tried the "Sony sudden death fix" holding the power button and volume up button, I get three vibrations, but nothing happens. I tried plugging it into the wal and the light turns red (top left). I tried unplugging the battery and replugging it back up to see if that did anything, didn't help. I'm at a loss as to why it's not working. Does anyone have a solution? Maybe I accidentally disconnected something?

Anyone have any advice?

edit: I hooked up my old screen and then re-installed the rear frame. Now when I click on the screen I can hear noises. What I'm clicking is the different language options on the start-up screen after a factory reset. I know this because before I attempted the repair that's the screen it was on.

I tried this with the new screen as well and the same thing happens, I can hear the click and vibration noises when touching the screen but I don't have an image on the screen.

I was reading that maybe it has something to do with jumping a resistor? Does anyone know anything about that?

I have this problem with my Z3 compact, I received a new replacement screen (broke the screen after me falling down and the phone being in my back pocket hit the floor first) and after fitting it, well it doen't light up! Everything else seems to work, the LED lights up when charging, power button works as it vibrates, camera button works as well (the phone vibrates when pressing it) so I think the phone does work.

Also I tried touching the screen, it does make the clicking sound, so the touchscreen is working.

The only problem is that the lcd stays black, no backlight, no images nothing at all! Tried to unplug the battery and plug it back in, still nothing. Volume+ and power did nothing as well.

Any advice or solution on this problem? Maybe the screen is just defective?

At the boot sequence with the display of the "android" font, it all looked normal but after that, the blue-ish start-sequnece (with the flowing lines etc.) was completely pixelated and scrambled. also the upcoming lockscreen was pixelated and scrambled in the same way.

Is it the mainboard/graphics unit or is it a faulty display?

thanks for help and advice!!
