if your connector is broken you need to a buy a new mainboard since HTC wont replace it.You can ask a local dealer if its available but here in india it isnt available..I dropped my phone and so i got a connector issue hence replaced the mainboard

Hello,
small up
The vibrator is just next to the flash, and it replaces easily
mainboard
Somebody tell me please the product number of European HD2 mainboard (NoT for US, they are different).
do we no anyone that supplies the main board yet, ???
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 !

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?
Hey Guys,
I replaced a screen on my THL 5000T and the volume/power buttom was attached to the main board of the phone with what looks like soldering flux.
I attached the part I bought to replace and hoping I can get pictures of the main board shortly.
Im looking for advise to remove the old flux and installing the new flex cable.
Thanks for giving the time !!

Hello.
I'm looking for poco motherboard schematics or someone able to figure out what one smd compontent that I'm missing is:
View attachment 4866007
Story: a friend of mine smashed his screen and somehow, attempting to replace it, he tore off the mhf4/ipex coaxial cable connector on the motherboard, damaged the one on the bottom board with the charging port and broke the cable itself. I'm not sure how.
I already found and ordered the replacement parts but after cleaning the area on the motherboard where the old port used to be I found that he must have also blown off one of the 0201/0402 capacitors/resistors next to that antenna port.
The one that remained right next to it looks pretty much the same, so I could take that one off, measure it, and order a strip of those but I'm afraid to break something if it's actually a mismatch.
I searched a couple places for the schematics because in the past I had luck finding a pretty long and detailed .pdf with schematics for LG G4 H815 which helped in a similar situation. No luck this time, though.
Here are some pictures of what I'm working with at the moment:

Yo igual estoy en busca de schematic del poco ojala alguien pueda ayudarnos
any update on this topic, i am also thinking to reballing my logic board.
Hi all ,anyone have a diagram of the board ? I also have some bad experience with missing one part from the board near LCD connector . which is causing it's dark and no reaction :/
By the way is there some option to make a backup from Poco ? Unfortunately I don't have USB debbuger on :/
Any advice on this ?
Here is a picture of the board with missing part [IMG="https://pasteboard.co/IYtC8mD.jpg"]
While swapping boards, buttons etc from one frame to another i too ripped the mhf4 coaxial connector from the board. I believe that this is a common problem with this board. I ordered replacement connectors from china to properly solder a new one in place.
It maybe a test point......
