Hi all,
After replacing the screen from a Z3 the network signal disappeared.
I replaced the screen together with the front housing assembly (mostly that is the easiest thing today, except for the xperia line I guess, it was prolly easier to replace only the digitizer).
The blue ARF cable snapped at the end, so I had to solder it to be able to attach it again. It was guiding a current signal so the cable was fine after fixing it.
Any ideas what provides a signal/network to this phone? Or should I just order a blue ARF cable.
Thanks,
Niek

Hello all.
While I was taking my HD2 apart to replace a cracked screen (glass digitizer) I accidentally broke the connector off one of the wires. The wire is black and a few inches long with a silver and round press on connector on each end. It attaches to the board that houses the vibrator motor and runs down the right side of the phone (if you were looking at it face down and partially disassembled).
Unfortunately, I lost the metal piece that broke off the wire (the thing is tiny!), so I can't just solder it back on. Any idea on where I can buy a replacement? I've spent about 6 hours today on ebay and google to no avail. Searching for "HD2 black wire" and anything similar is hardly efficient, but that's all I know about it.
Any help appreciated.
Thanks,
Chris
Good question, I think I damaged the cable to the volume buttons so it would be cool if someone has an adress where we can get spare parts except LCD and Digitizer..
this guy on ebay seems to be selling an HD2 in parts. you might find what you need here:

Thanks, I sent that guy a message and hopefully it'll work out.
Anyone else have a source?
connector of my hd2 is also broken HTC says that the mainboard must be change and I have to pay € 230 because that is my responsibility
I think you have damaged your coaxial cable connector for wifi and bluetooth. Google will help you perhaps.
I believe that my wifi/bluetooth cable is broken, as I have no wifi or bluetooth signal since dropping my phone as reported in a previous post of mine. Can anybody advise me on the difficulty of undertaking this repair myself, does it involve complete disassembly of phone, any soldering etc. If this is the case I don't feel confident enough to do this so does anybody know of someone who does this sort of repair, I have found the cable on e bay for £7 and it looks like it has push on connectors ?
if the connectors on the boards are not broken then all you need is the coaxial cable with connectors on the two end. you need not disassemble the whole set, just open the back cover, connect one end of the cable to mother board and other end to the rigid flex board and that's it.
WiFi and Bluetooth not working

Do you think that this is my problem as since I dropped my HD2 I have no wifi (unless sat ontop of router) or bluetooth or fm radio, is it easy to get to the coax cable by removing back cover, whereabouts is it ?

Fixed it, opened up phone and spotted that at one end of the black wire the connector was not pushed onto the motherboard securely, I pushed it home and hey presto, wifi and Bluetooth now working, phew, Thanks for your help !

I opened my tablet to try and fix the signal strength on my wifi and gps. everything was going great until my screen turned a little and bam... the ribbon cable came out of the connector. When I went to pry the lock up it broke(very cheap connector). I tried to insert the ribbon back in but I noticed when some of the black plasctic that broke away there were wires that seemed to run through it. Anyway long story short. Can I remove the connector and wire the ribbon to the board? Is there anyway to fix it other than ordering a new pcb board? Any ideas would be appreciated. It is working now but there are spots on the screen that do not accept input or touch. I have used electrical tape to tape it in place for now. Thanks inn advance!
Sorry bro I think your s.o.l. those ribbon s are not really repairable and the main display one j think has 24 connectors or so. Soldering those is next to impossible. Same with the touch panel ones.

good afternoon,
My xperia mini pro sk17a has a black screen.
Prior to this occurrence, I had a bad flex ribbon cable to the sliding keyboard. Screen would go black and come back with sliding keyboard motion. Opened the phone and found that the cable was torn. Decided to buy a replacement flex cable and installed it. Everything looked okay but...
Once I put the phone back together, no screen at all. If I turn the phone on, there is a very very faint amount of light present (you can only see this in the dark). The phone does boot, and the notification light will flash indicating new messages. I can call the phone and it will ring.
Hoping that this might be some sort of software reset, I tried flashing with the SUS software. No help, phone still behaves as described above. I'm guessing I need a new screen (maybe damaged it somehow taking the phone apart?), but has anyone gone through this and know of a solution other than more new hardware?
Thank you in advance for any help or feedback.
I think new flex cable is also damaged. You should check flex cable in another SK17.
Hi all,
Recently, I bought a Sony Xperia Tablet Z of which the previous owner had removed the whole screen. Tablet was working, then he dropped it, causing the screen to be broken (LCD was blacked out, tablet and digitizer/touch still working). He removed the screen assembly as a whole, had the intention to replace it but he just sold the rest of the tablet.
So I obtained an LCD/digitizer assembly form AliExpress, but after installing the screen and switching on the tablet, I got the same problem: Touch is working fine, tablet switches on nicely, I get some kind of 'blind-modus?' that responds to touch with sounds, it tells me I'm swapping through menus, but the LCD itself does not give any signal. Linking it to PC works fine too. Linking it to a TV requires an MHL cable, which I don't have...
My question is:
Does anyone know if this is a well-known problem after dropping an Xperia Tablet? I'm more or less sure it's not the LCD of the replacement screen that causes the problem (given the background), so the problem might be in the LCD flex cable, or worse, the logic board. But how to find the faulty component?
For the flex cable: I've tried to measure (multimeter) the resistance of the wires between each tiny pin of both the connectors of the ribbon, but it's not easy. Some pins on one connector are linked to multiple other pins of the other. Is there an easier way to check this, anyone any experience with this?
If it's the logic board, is there any way to make sure which component is broken, and is this fixable?
If it might help: I have a set of pictures of the logic board / flex / LCD.
Otherwise, I might just try and stop by a tablet/phone fix shop, ask kindly if I could quickly check one of their screens/cables to verify which parts are working/broken.
Thanks in advance!! Kind regards
Edit: I just noticed there is a specific forum for Xperia Z (one), this thread belongs there, sorry! Could this thread be moved there?
I've been working on this problem off and on since the summer and have read through pretty much everything I can find (some similar posts with no resolution). After about 6 months of using a Galaxy S6, I want my Xperia back.
Long story short, I replaced the screen on my Xperia Z3V a while back. I'd already paid Sony for one screen on this phone and didn't want to do it again (wish I did). After I replaced the screen, the phone worked fine except I no longer had "proper" cell/4G signal. When I say "proper," the signal randomly appears (4 bars/-87dBm) and randomly disappears (-120dBm). I can't find any pattern to this. In some places with very good signal such as the Verizon store, the phone will try to activate but will fail to make calls or receive texts after.
List of what I've tried so far:
- factory reset
- new SIM from Verizon
- new antenna cable (blue coax cable, clips into side of phone)
- new antenna
The part that really confuses me is that disconnecting the blue coax cable has no effect. I.e., if I disconnect the cable while the phone claims to have signal, nothing changes. My assumption is that signal would instantly drop.
Is there anything worth trying before writing the phone off?
Possibly related... There is a white putty along the bottom of the battery that turns into a flat white cable which runs up the length of the battery to the WiFi antenna. Can anyone tell me what this might be? I can't find pictures describing this phone anywhere.
Thanks in advance.
I have a Z3 and the blue coax cable is the one for signal, in this case it seems either it is broken or something along those lines, as I have the same problem in my z3 but I know why because I had broken the coax connector so the signal issue. Try checking the antenna at the bottom or the connector on the motherboard itself

That's true. You probably damaged the coax connector on either the motherboard or the loud speaker side. The proper procedure for removing the blue cable is holding down the socket with one tool and removing the cable with another. And best is to remove the speaker module without touching the cables...
Hmm... I did not realize the coax cable was quite that fragile. Lesson learned. It seems impossible to find brand new replacements for this particular phone, I wonder if Z2 or Z3 parts would fit.
The old iPhones I've successfully replaced screens on seem like toys next to the Sony...
