I have a Sony Xperia Z4 Tablet, Model: SGP771. After changing a cracked screen, with a brand new original Sony screen, the screen work but it doesn't light up. I mean it shows information and the touch sensor works, but the LCD light is not working.

I tried two different screens, and i get the same problem.

Any idea or suggestion with it?

habe beim besagten gerät akku und display tauschen wollen. nach dem wechsel beider komponenten reagiert das gerät zwar auf den power button aber das display bleibt schwarz. auch das alte display, welches nur einen glasbruch hat, bleibt aus. auch wenn ich den alten akku einsetze geht es nicht an.
Im hintergrund höre ich wenn ich die wippe drücke merkwürdige 8 bit sounds, auch wenn ich das display etwas mehr in den rahmen drücke.

Jetzt habe ich (siehe kommentar) gesehen, dass mindestens 2 Federkontakte beschädigt bzw. einer ganz ab ist. Könnte das der Grund sein oder sind die nur für den wlan empfang?

just a quick one. I googled it, youtubed it and no answer... Can't believe there is absolutely no info on internet of how this is done??

People are saying if it isn't on youtube - it doesn't exist

Please if someone could prove me wrong and share a link to a video or tutorial

How to open Xperia Z3 tablet? How to change the cracked screen for example, or how to get to the battery to change it?

I know there's no video tutorials of how it's done, but maybe at least a photo-tutorial or text guide?

Any help would be appreciated.

I have a problem with charging circuit.

Firstly i had 5,0 V from the micro usb port (Then it was showing 1,35 Volts on battery + contact - which is low - Should be around 4,3 V?)

I removed the 6031 IC + 8620B0 and now i am getting only 0,7 volts from the micro usb.

Have anyone experienced something similar?

My Tablet Z2 has had a broken microUSB port for several years because the repairs person refused to repair it, saying that trying to repair it will likely break it. Looking back, I wonder if he either witheld something or was just too afraid, because I ended up finding a Tablet Z2 teardown video on the official Sony YT channel where it gets completely disassembled and reassembled, but regardless, my mother (it was her who presented me the tablet and she took it to repairs back then because I was busy in the university) believed him back then and kept yelling at me for even thinking something different ever since. I ended up buying a magnetic docking station for it to bypass the charging problems, and that is how I kept using it for several years, until recently.

Not long ago, the docking station stopped working when I accidentally spilt my coffee on it. Now when I try to place my tablet on it, I no longer feel the clicking sensation that usually allows me to understand that the thing is in place and charging. I came to a conclusion that this must be the problem with the docking station, and while I did manage to find replacement docks on a third-party site, this event made me reconsider the idea of repairing the microUSB port, since there may come a time when I may no longer find any replacement docks out there. While I did find the teardown video I mentioned above, I am quite confused regarding the repair videos and finding the replacement part.

I watched a few repair videos on the Sony Xperia Tablet Z, a previous model from the same line, and they featured the users replacing the broken microUSB port alongside the connector part (or whatever is that yellow thing attached to the metal port called). However, the teardown video I watched does not focus much on the microUSB port (only what is holding it together), and my searches for microUSB ports or repair videos specifically for Sony Xperia Tablet Z2 yield nothing. I also know that the placements of the microUSB port are different for most models in the line (as are the placements of most components), so I can’t just buy a part from another model and put it inside my Z2 tablet. I did manage to find a bunch of different metal USB jacks, including the microUSB one. Which in turn leads me to my first question: is the microUSB jack inseparable from the connector parts? Is it even possible to just grab the metallic part, somehow detach the broken one and reattach the healthy one? Or is there even a connector part in the Z2 tablet? I didn’t notice one in the video, though I do suspect it might have been due to the engineer not focusing on it. What kind of parts exactly should I look for for Z2 in particular?

My second question would be the choice of adhesive. The videos I have watched had people use double-sided tape to apply the new adhesive layer. I wonder if this is the right thing to do it, and if yes, which ones exactly should I be on the lookout for (I see different ones available for purchase, some thicker, but also boasting waterproof qualities, as well as the thinner ones). If not, what exactly should I look for?

Finally, is there anything else you would recommend me to pay attention to? Since I am a newbie in repairs, I suspect there might be something else that I overlooked. I’ve been warned about needing special screwdrivers already, since it seems that manufacturers like to put unique screws into their devices to complicate repairs for people outside the industry, but I bought a few sets of tools for electronics, and I guess I have to open it first to see what exactly I need (since the seems to be painfully few videos about Tablet Z2). What are the other important details in this type of repair that I should know?

Thank you for your help,

Eli

My Sony Xperia tablet Z had a problem with the charging port, after replacement the battery is now fully charged but the tablet wouldn’t start!!The only sign of life is when connecting the charging cable, so the screen stock in blank just after the logo screen and the 100% charged battery screen.

I’ve tried all the ways to reboot it but nothing worked, power+vol up, power+vol down, power+ 2 volume buttons or even disconnecting the battery!!

It seems like that the power button is not working! But even with connecting the power cable it’s not working!!

Any idea

Thank you
