I bought new LCD touch screen but its not working even the power light is on !

I checked all connectors but nothing change..

I replace a display from a Xperia tablet Z and I tested it before installation. When I tested it everything is OK. I applied double face tape around the frame and I install the new display. I try to turn it on but the display won't show image.

PC recognize the tablet when I connected, I made a firmware upgrade, but the display won't work. I check all connections to logic board and everything looks good.

Please help me

Recently, I bought a Sony Xperia Tablet Z of which the previous owner had removed the whole screen. Tablet was working, then dropped it, causing the screen to be broken (LCD was blacked out, digitizer/touch still working). He then removed the screen as a whole and sold it.

So I obtained a LCD/digitizer assembly on AliExpress, but when installing the screen I get the same problem that he had: Touch is working fine, tablet switches on nicely, but LCD does not respond to anything.

My question is:

Does anyone know if this is a well-known problem after dropping the Xperia Tablet? I'm more or less sure it's not the LCD of the replacement screen that causes the problem (given the background), but how to find the faulty component?

It might be the flex cable between LCD/Logic board? I've tried to measure the resistance between each tiny pin of both the connectors of the ribbon, but it's not easy. Some pins are linked to multiple other pins. Is there an easier way to check this?

If it's the logic board, is there any way to make sure which component is broken, and is this fixable?

I have a set of pictures which I'll upload so you can see the logic board / flex / LCD, maybe this helps.

Thanks in advance!! Kind regads

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

• when turning on, LED sequence executes properly.
• even if the screen is black, I am sure the tablet is turned on at this point because my pc detects it via usb cable.
• proper behavior also when turned off via power btn + vol up for 10 seconds.

As said, the tablet was working with the old broken screen, but now it's completely black with the new part. I suppose this is a faulty replacement part problem?

'''UPDATE: when the tablet is left turned on, at some point like after 30s or 1min, a blue notification light blinks, which is what happens when I detach the flex cable that connects the LCD to the motherboard.

How can I tell it's a faulty LCD and not a faulty flex cable?'''

Where is located Gps, Giroscope & accelerometer module in the Tablet Xperia Z. I'm thinking open up to clean those terminals or change flex.

Actually my screen doesn't rotate automatically because I put my tablet into the pool and it got wet inside.
