Hello there, with placing my keyboard part in a new housing i damaged the flexible circuit of it, now some keys dont work anymore.
I was looking everywhere to buy a broken herald or wing so i can take the keyboard from that one. I cant find the keyboard circuit as a part on ebay or webstores.
Maybe anyone on this board has a herald with broken lcd or defect hardware except the keyboard hardware?
Any help or suggestions will be appreciated!

I'll describe everything from scratch so you'll know what the problem is. So, I had 2 MDA Vario II, both developed a fault (on one when I pressed the button on na hardware keyboard it showed two letters on the screen instead, on the other the backlight under a couple of letters stopped working) so I dissasembled them and out of two faulty, I had one working and one working so-so.
As I wanted the other one to be sorted (the connector to the hardware keyboard was burned in some places on the mainboard and the keyboard tape connector as well), I was shopping for some faulty ones on eBay and yesterday I bought an original TyTN with LCD screen not working. I dissasembled both of them and connected the full LCD fascia with the screen to the mainboard of the TyTN (so that now I've got the LCD housing from T-Mobile, but the rest from HTC) and everything is working perfectly... however I'd like to use TyTN only housing and possibly buy a new one on eBay (but keys on the bottom are different for Vario II and TyTN).
I do know that LCD screens are incompatible, in the TyTN I have the HITACHI and in Vario I got the TOPPOLI (however the whole thing works with the mainboard, as both of them have the same product codes)...
But does someone know if I put the whole LCD from the Vario including the tape and top buttons in the fascia of the TyTN and connect it to the bottom buttons circuit, it will actually work. I will do it anyway, but if someone was doing it in the past that would motivate me to fiddle with it tomorrow
Sorted.
For all those with NOT working LCD screens/keyboards/mainboards...
As I the LCD screens are not compatible and we often do not know what we are going to get off eBay, lots of people face the problem of buying something that may not work with their version.
I needed the mainboard and the keyboard in my Vario II (HERM300) and I bought HTC TyTN (the original one, HERM200) with not working LCD (backlight working but nothing could be seen on the screen). As you may be aware that TyTN has got an extra button for 3G and Vario II not, I was wondering whether the whole thing would work. I replaced the full LCD screen with the tape including the two top buttons and connected it to the bottom circuit of the original TyTN. After assembling everything back, I switched it on and it's working without any problems. So if you have the same problem and can get hold of a cheap Hermes for spares on eBay, as long as you replace the whole lcd with tape it'll work regardless of your version...
Useful info thanks. That question was asked before and I don't think anyone gave an answer. Good to know it will work despite the different button layout.
cheers

After replacing the main board of my HD2, the keypad no longer works. At first the button on the left (answer phone) was still working while the other weren't but after reseating the flex cable of the keypad, none of the keys work.
I don't think the main board (or the connector) is broken but I will be able to test that soon enough since I ordered a replacement keypad board. I will be able to just plug that one in without having to disassemble the HD2 to check if it's indeed the keypad that's broken.
But if the keypad is indeed broken, I will need to replace it (obviously). I can find how to disassemble the HD2 (video's, pictorials, etc), but nowhere can I find how to assemble the HD2.
For instance, you will need to separate the screen from the chassis by heating it up (with a heatgun or blow dryer) since those are glued/taped together. But I can't find anywhere how to glue/tape those two parts together again.
So can anyone direct me to some instructions? Or have any tips?
(Shameless) Bump?
So my friend got huawei X5 U8800, it had shattered screen which worked fine. So he bought new screen (I think it's called digitizer, the LCD itself was intact) and installed it. Now only the soft buttons work. Is there something that could cause that? Apparently there was only one ribbon cable to connect.
Sorry if I'm missing something obvious.
If the soft buttons work, the problem might be in the digitizer, as the soft keys are actually just extended touch screen. So it might be a faulty digitizer. And there is only one ribbon cable on the digitizer connected to motherboard.

Thanks for your input. I'm not very familiar with these screen replacements (never had to do one). So can I assume that it should work like "plug and play"? If that the case then I assume that the phone itself has some problems of it own or the digitizer is faulty like you said.
Also sry for my english, not my native language etc.
Hello,
Where can I find a good replacement for HD2 digitizer?
I have Windows Phone 7.8 on it (I had the same problem on Android) and sometimes when I am using it, the digitizer registers my touches wrong.
Seems to be the left side is most affected by this - Like when I press e, it presses q also, or w then q too. Also happens with s (a) and symbols. Cannot even pinch to zoom.
This has rendered my HD2 a unpractical phone. It started randomly last summer.
Should I change the digitizer in this case or is there something I can try?
Also, my input jack is messed up - when I have a headphone connected to it and the plug shakes in the slightest - The phone things I want to pause the song or play it. Also activates the voice search which is a freaking PAIN.
Can anyone please help me and tell me what I should do about these issues?
Digitizer & other parts such as assembly tape can be found on eBay.

Audio plug maybe harder issue to rectify, it can be replaced but requires a good solderer to do good job. You may improve things by cleaning socket & cable plug & trying to improve contact spring arms tension position in socket with a pin or similar.

But does this issue seem related to digitizer being faulty or just a cable a bit damaged? Sometimes the issue appears and sometimes it doesn't.
Ribbon on digitizer is all one piece & any permanent repair usually is only really achieved by replacement of digitizer.
I have had similar issues of screen presses activating other area on screen & dead zones on digitizer error & also the more common no touch issue, all required digitizer to fix .
Anyone know where to find a replacement jack in the USA??
