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

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

I ordered a new replacement screen for my z3c. Yet, on replacing it I realised that the digitizer cable keeps getting loose from its socket (?). Thus, while the screen itself functions, it is unresponsive to touch (of course, since the cable does not stay attached to the socket. Any ideas ? I have my old screen that is responsive to touch but has a broken lcd - can I somehow use its digitizer on my new screen?!

I hope my question got clear - I am missing a lot of technical vocabulary in English.. Sorry.

Cheers

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?

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 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

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?

I was able to start it by connecting it via USB and fastboot. It starts OK, calls, camera, network is working fine. The only two things that don’t is power and camera buttons. I could not give a thing about latter, but I need the former :)

Any advice what could I do? Does it smell like a mobo damage or the main flex? Inspecting the cable did not yield any visual damage.

Thank you!

The battery capacity of z3 compact is not so good, compared to these days phones, of course it was good back then when released.

I'm wondering if it's possible that I can replace the battery with another (more capacity) one? Maybe from another phone… is it possible?

If the dimensions fit and I could make it to connect to the board, will it work as expected a without harming the board?

What may happen?

What could the problem be ? Can signal cable must be well resolved or broken ?

Hope there is someone who can help me with this problem .

The lower half of my screen has recently started to randomly click things that I don't l want it to, which obviously makes it nearly impossible to type.

I've tried cleaning the screen, as there is no major damage to it (a few light scratches), but to no avail.

Any ideas? I really don't want to get a new phone, as my family is in kind of a bad spot for money at the moment.

Is my phone for sure bricked?

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?
