Hello. I got this Z3 with a broken screen, when I got it it had only black backlight, no image, but the LCD cable on the bottom was cut, so I thought that was why it had no image.
So I replaced the screen with a new one, but the issue remains, no image, only black backlight.
Tried restoring the software with Sony PC companion, updated to latest version, but it didn't help.
The phone boots fine, touch works, I can select options and sometimes I even get audio readouts of what is on the screen, just no image.
Is this a dead motherboard or something else? Because I went through a couple of new screens, none worked, so I'm out of the ideas.
I haven't encountered a case like this before, the screen either works or doesn't, the fact that the touch works and I have backlight puzzles me. No backlight or no touch issues are a common case to me, but this is a new one.
Can someone help here?
Thnx

It's a faulty LCD connector on the motherboard, in my case. Not the connector itself but the small jumper just above it, it gives power to the LCD, it was broken off.
I had it resoldered. Works fine now.

No image at all, only black backlight ant the touch was responding.
The three square fuses on the bootom of the picture, it's similar in Z3, in my phone one of those was broken off.
Hi guys. I have almost the same problem but inverted. My display and touch is working but i dont have backlight. I can see the screen only if i put light on it.
Maybe u guys have a faulty digitizer responsible for image faulty(no image), better for send repair, flashing new stock firmware will not help
I tried with new digitizer, no luck. Tried jumping the fuse with no luck. Don't know what to try anymore.

Put the motherboard in the oven and bake it for a few minutes, it resold everything, if that's the problem, it will fix it.
For more infos and temperature / time, google it

z3 no display but backlight on
by jumperig the fuse near lcd conector it turns on the backlight .There is another fuse surrounding power manager ic which may got open & display ic is not powering.
The phone is Sony Xperia Z3 dual d6633
The problem: The phone gives no diplay but the sound is working and even when I press the camera button it gives sounds as if I'm taking pics...
Tried Solution: I replaced the LCD twice with new ones, and replaced the Main flex cable but still not working.
The phone actually was fixed before but I don't know where it was fixed. There is a thin wire wielded on the main board and I don't know where this wire should be connected! I took some pics of the main board and the weilded wire , please if you have experience with hardware or you've seen similar situation like this tell me what is the function of this wire and where should the other end be connected to?

Hi guys, New to the forum here and in desperate need of some help here!
I have a sony xperia Z3 and ive just replaced the screen and the frame after smashing my screen only to find that when I try to power up the phone, I get nothing.
It will charge and I know it isn't the screen or anything like that because it says its charging on the LCD. My thought are that the power button isn't working, Anyone else had the same trouble?!
All help appreciated!

Hi, guys im having a problem with my z3 sometimes it only vibrates but doesnt turn on, sometimes it doesnt go past sony logo turns off and sometimes it turns on.. My z3s screen used to flicker from time to time so I thought of buying a new screen but I just canceled my order as I thought if it shows the sony xperia text its not a screen thing, idk if its software related cos when *rarely* it boots I can use it normally. I have its back cover opened whenever I try to turn it on there is a noise on the motherboard (dunno if its normal) if any of you have any suggestions you are welcomed!
My d6603 has the same issue (flickering,all that u mentioned above),have you managed to fix it pls tell me how....( Cant use flashtool for rom flashing)
Unfortunately no, I concluded its a motherboard issue so im looking for a new one...
