Touch Dual digitizer
Hi Saliml2
Not convinced it is a software issue. My digitizer on T-Mobile Touch Plus did the same thing. It stated behaving erratically and then stopped responding altogether. I replaced the digitizer (via eBay) and it work for a few days and then stopped again.
I have read around the internet and have tried several ROM updates etc (currently running a WM 6.5.5 found in other area of this forum) but this has not solved the problem.
It seem to be an alignment issue - i.e. screen alignment is outside the screen area, but there seems to be no way of getting it back. Could be a fault on the phone mainboard (?) but there doesn't seem to be any info around apart from sending it to HTC for repair (not viable as the phone value negates this)
My phone is still not working, I might try opening it up again and reseating the digitizer cable but have done this twice already.
Have you try change the flex cable?
I had one to, with the same problem, and after changing the flex everything was ok...
Good luck!
Hi Amokh Just to clarify, what is the flex cable? The digitizer has a cable already attached to it that plugs in to a zif connector on the mainboard - I assume that this controls the data flow for the digitizer.
Any help would be appreciated.

Flex cable, i was mean the cable between the mainboard and the lcd block, you can see it in the previous link, picture 20. Have you try it to change?
hello guys how did you manage to put the digitizer cable in place mine doesn t seem to get in place do i need something to hold the connector in place???

So I cracked my LCD screen, bought a replacement, opened up the phone w/ little incident (man they really do cram a lot in there!) and I powered it on.....
the screen is just white, if I fiddle with the connection at where the LCD connects into what I believe is the digitizer I can kind of see a keypad button layout.
What do these symptoms describe and does anyone have a link to the service manual?
Thanks in advance for your time.
I had to replace the LCD on a wizard so here my experience... Make sure the two data ribbons are inserted securely. Also, before you power on, plug your hermes into your computer (assuming your computer is on and logged in as an admin) via USB (this sounds weird but I had to do this for some reason....) and then turn on the wizard.
If you still have a problem, you may have damaged something more than the screen.
Good luck.
Ok I will give plugging it in a shot.
Before you plugged it in what did it do when you powered it on?
anyone else have any input on what the issue could be?
It could be wrong LCD. There are two types of LCD for hermes/wizard with same connector but they are different. One is with gold flex cable, the other is with black flex cable. First one is most popular on wizards, the other on hermes. Check what was the color of your previous lcd flex cable and the new one.
Instructions
Can anyone post the instructions on how to take the lcd apart ?
I have gotten this far

I'm a bit afraid to go on without instructions
Here is the lcd I got

I've made sure I purchased the correct replacement for my screen. Followed a guide and got it all hooked up. The phone powers on but I get a white screen.
Anyone have any guesses as to what could be causing this?
Your help would be much appreciated as I would hate buying another phone.
Incorrect ribbon cable seat.
Take it apart and make sure that both the ribbon cable on the side, and the bottom with the tiny black screws are properly seated.
Yea i have tried all of that....but I just tried tinkering with it again and i was able to get a partial picture by changing the back pressure of where the LCD ribbon plugs into the other ribbon assembly the buttons are connected to.
So I am guessing there needs to be a super secure conenction at this point. Problem is...the black latch that holds the cable from the LCD to the other ribbon is broke so i cant make it pinch the cable.
Anyone know where I can find a replacement for this other than buying a broken hemes for parts?
You need the flex cable connection, and there is a site in canada that has them.

Yea I checked that out....I don't see it, do you?

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:
http://stores.ebay.co.uk/Right-Click-Enterprises/_i.html?_nkw=hd2&submit=Search&_sid=131407386
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 !

Hey there
So I changed my Xperia Neo's panel as carefuly as I could
I turned it on but the touch screen doesn't seem to be working although the ligh sensor is functioning properly and all the buttons but when I press the screen it doesn't register the touch could I have broken something or might this be some other reparable problem? :crying:
Thank you for your time.
I found the problem - I've cutted the cable of the digitizer :/
I would like to advice unexpirienced people like me to be very careful when replacing parts of their phones, watch for the tiny cables
Regards!

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?
