Just bought a new screen for a cracked hd2 and hit some problems. Firstly, its a uk hd2, so it was a solder connection, i bought the screen + digi from ebay and noticed it was a ribbon connection (not sure if that will make a difference). When undoing these plastic clips
http://imgur.com/Faiyig3
Both broke. They were so brittle, has anybody seen/heard of a way to fix this? I put it all back together and the screen does come on, but touch doesnt work.
Can anybody tell me what these cables do? Is one for touch, what about the other?
Gutted about my hd2, its been going so well all these years...is it fixable?
Not good :-/
those 2 clips: one is the flex ribbon connector & other is the LCD ribbon connector.
The ribbon from LCD also is feed for digitizer.
Not sure if the locking arms are replaceable by themselves ! will look at an old mainboard & see.
you may get some function by bending a very light V in the ribbon so point of v is ribbon contact face & thus pushes tighter in socket promoting better contact.
putting a bit of tape on back may help too! be careful though as actual socket is very fragile too ...

Tell me about it, thanks for explaining what the ribbon connectors do...I couldn't understand why the screen would turn on if the connector was broke. That's a good idea about slightly bending the cable, I will try that tomorrow afternoon. If i could swap them out, that would be awesome.
Thanks for answering, I appreciate you talking time to help a fellow hd2 fan!
Have made none working digitizer work via creating very light v shape bend in middle of contact area (bending across width of cable)
Do be gentle though ... not sure how successful it will be without clamp though :-/

I wanted to change the touch screen on my QTEK 2020 and I bought a new one a few days ago. I opened tha PDA, but when I tried to pull the touch screen off, I damaged a slim orange cable on the back of the screen. Specifically, I pulled a black sticker and it took along the two cables that were on the circuit on the screen. I don't care for the touch screen's cable, but for the one of the screen. I have scratched the insulation on the cable and I have a question. If I just put over the circuit the nakes cable and glue it a little belower, would it make connection? Or have I to solder it? And How am I going to soldier a cable like this that's naked from the side that I don't see when I put it in place, without even melting and damaging for good the screen or the cable itself? I have some pics, too for you to see and understand what's going on. Please help me, as I am a young man with prospect and I want to learn things like this and do stuff more than the usual.
OK, I couldn't wait for advice so I soldered both cables. The screen turns on and it needs to be aligned. I tap the screen, the touch screen works, but when I finish the alignment, it starts from the beginning, the cross in the center. It asks to be aligned constantly. I haven't assembled the PDA, I have it like the pictre below. Is this the problem it doesn't start, or do I have to put the touch screen somehow differently? I have it centered and tried to align tapping a little upper, lower, left, and right from the cross, but nothing.
Please HELP!!!
OK, no worries! I fixed it! It took me all evening, but I'm completely satisfied. Solder this, solder that, make a bridge because a connection was damaged with all the scratching, but it worked!
cong. dominator happy that you have finally fixed it :wink:
Thanks Kbantikos my boy! And here's the bench and the heat tool I used! That's the only that I have. No doubt it took me 4 and a half hours to complete.
Congratulations! I'm not kidding, saw a lot of "homework" results, in some cases, display was damaged beyond repair.
You get the working display, so you are lucky .
Thank you, my friend! I didn't believe my eyes when it booted! It still works fine, even if it fell off my hands one time!
my touch screen is really quite dull / lacks brightness even when on the high setting
i've aquired an XDAII that isn't working but i know its screen was bright when it was working
my question is: what do i need to be looking out for / be carefull of when i replace the screen
what would you do differently?
thanks
Larry
You'll definitely have to look for that orange cable that's not of the touch screen. on the back side of the screen there should be a black sticker. When you try to pull it over, it takes the cables, too. So pull it from the side of the touch screen's cable only. You are gonna need to solder the new touch screen for sure, just placing it won't work. Scratch the side of the cable that's going to be placed on the circuit on the back of the screen so that the metal contact on both (touch screen's cable, circuit) is naked. Put solder on the circuit's contacts. Then put the cable on top of the circuit, but a little lower. Now, burn the solder holding the cable steady and connect that way all four contacts. I hope I was of a little help, observe my pictures and good luck!
Just about to try this myself.
Touch screen bought from - http://stores.ebay.de/hitechhk. Arrived within 1 week.
Removing the black tape on the back of the screen, even very carefully, pulled off both the connections for the touch screen and another connector (the back light I think)
In hindsight would recommend only removing the tape around the touch screen connector.
As soon as I find a small enough tip, will resolder everything.
Detominator7, how did you change your digitizer? cause i need to replace mine too, but the seller is talking about soldering it. i already open my pda and all i can see is there is only plastic cable. how do you solder on plastic?
Your touch screen might have a cable that plugs into a hole and does not require soldering. You know, like the fans we use on PC.

good job! I have the same problem and so i got a new touch screen but i cannot get over the calibration thing same as your problem before can you give me some tips as to what to do im just about to give up and get a new lcd.Only thing stopping me is the price of a new lcd.
What kinda adhesive do they use on the back of the screen
I'm talking about the clear glue type adhesive on the back of the screen in order to hold the ribbon in place
here's a pic of what I'm talking abouthttp://blog-imgs-3.fc2.com/i/n/u/inuchanbt/CHT9000_dismantle12.jpg
The gold/copper ribbon glued to the screen
had to replace my brothers screen about 3 times and now its barely stickin
it's a kinda like double tape. u can find in office stores
I hard reseted my O2 XDA II & I had surprised the screen aligning can't be passed.
Can somebody help me with ROM Flash or maybe some hardware tricky?
I use WM5 from C_Shekar.
PM me if anyone replies this message.
Thanks, Berns.
So I bought a new housing for my O2 XDA II Mini, during the removal of the display ribbon I broke the little black part on the display connector which holds the ribbon down, and after hours of trying to get the ribbon back in and secured I have bent the pins in the connector to buggery.
The ribbon appears to be untouched, however the connector which the display ribbon goes into is broken.
Is there anywhere I can get hold of one of these little connectors to replace my broken one, obviously very sensitive soldering will be needed to remove the old one and solder the new one in place.
Alternatively, does anyone know any mobile phone repair shops in Auckland, New Zealand who would be able to help out with my situation?
I fear all i'm going to hear back is "the motherboard needs to be replaced", however I am determined not to go through this route, as I am a poor student and the phone sounds as if it functions fine, makes the beepy noise when first starting up on the setup screen.
I was very careful with the actual screen unit while removing it, and I have had signs of life earlier on in the broken connector episode, however I can no longer get anything showing as I can't fit the cable in.
Cheers for any help.
Anything would be appreciated.
"obviously very sensitive soldering will be needed"
And that only can be done by machines/robots. I don't think humans are even able to sloder those kind of connections...
But, could you post a picture? cause I might have suggestions on how to fix it. One would be to bend back the pins on the tiny slot with a toothpick and when done to tape the flatcable, so it stays there.
I've maybe got a spare creen for you.

Hi, I've still got a SPV 500 and a MDA Compact, need to find it if you want you can have my MDA Compact screen.
Just PM if you are interested.
Hi.
Does anyone has been had this problem by replacing a digitizer to a G1:
I bought a newone digitizer for my HTC G1, after replace it and assamble it, the digitizer did workd at all. I retryed a lot of times and nothing. I test digitizer on another device and it worked fine. flex and cables were tested and all goods.
Any idea? any help?
Thanks.
Somebody having the same issue?
I have made that mistate before but if you know how to this this already just ignore what I say,
Check to make sure you connected the ribbons to the connectors correctly. There is a tiny little lever that is the lengh of the connector located behind the slot at which the ribbon inserts to.it should lift up and down, use your nails or a little toothpick. You must lift this lever to release the pressure on the ribbon cable in order to detach it. When re-attaching it, ensure that the lever is in the up position, then lock the little lever down after you insert the cable. Hope that helps. And remember be careful with the ribbons because if it rips just a little bit it wil cut the circuit.
Solved!!!

I just found this fail in motherboard.
It was due to a rised pin at the cable connector. After a deep clean and apply my hotgun, Done!!!
In the process of replacing my lcm, I managed to tear the button flex cable that connects to the mainboard.
I am currently looking for a the button flex replacement. What is the best way of tracking something like this down without going to HTC?
If there is no current seller/merchant available...Um...Is anyone selling an HTC HD2 for parts!?!?!?
Pics included...You can see the button strip, and the little 45 degree angle break on the flex..SUCKS!
I saw the break... Man, that's bad luck...
I hope you find a new button strip. The only other solution would be to solder fine wires from the point I highlighted on the photo. But that is very very very difficult... If you decide to do so until you find a new button strip I would recommend you to let an expert solder it, for example a television-technician. That shouldn't cost you more than a bier for the technician!
Wish you luck!
This just in, I have since purchased a broken hd2 and replaced the button strip. It has a light adhesive and is mounted on two small plastic posts on either end. To loosen the adhesive, just apply gentle heat (blow dryer) and GENTLY peel off. You might come across a stubborn part and want to give it a harsh tug, but you need to methodically peel it up using some sort of flat piece to get from underneath it.
Another torn flex Anyone has spare one or knows where can I get it?
I'm sorry but can't help. I get parts for iPAQs from iPAQ Repairs in the UK. I'm surprised there isn't something similar for HTC parts.
I'm interested in what an 'lcm' is. I've seen it mentioned but with no description.
i need one of these too. i hate htc's policy in not selling parts directly.
This button board should only be like upto $40 usd.
im needing a main board charger soxet broke if price is right ill sell
I have the same problem ....you solved?
where did you buy?

You should be a good electronic technician or know a good one. Otherwise I advice you not to try. I am a ordinary technician and I can say that in my case it was very very difficult and even if I tried hard, I wasn't able fix all connections. Only two of my buttons work right now.
How to Replace Button Strip?
Anyone know of a link showing how to replace this strip? Either I can't find key words for a search or there aren't any good videos out there. - thanks
Good to hear I'm not the only one to snap it so easily. Ordered a replacement from e-bay.
Sorry to dig up an old post but, I need that little wire that connects the wifi/bluetooth module to the main board. I replaced the digitizer in my phone and I somehow jacked up one of the ends on the cable. Anyone out there have parts?
I was cleaning the dust out from behind my screen and I disconnected the cable that is glued to the top of the touchscreen. I put it back in place (as best as I could) and let the glue set, but my touch still doesn't work.
Is this something I can fix with better alignment (and maybe a little bit of conductive glue) or do I need a new digitizer?
Has anyone else done this?
where was the cable actually plugged into? I am assuming you just have to put that in and shut the rubber clip (I apologize to the community for my lack of technical terms) but can be a bit difficult depending on what tools you have
I had this happen too. I had to buy a whole new digitizer.
Damn. Thanks I guess :/ I'll find a creative use for this one. I wonder what my atrix will look like with all the paint removed <_<
It winds up plugged into the same ribbon as the speaker and front camera I think, but its on the glass end that my promblem lies. The metal fingers on the wire are glued to the ITO fingers on the glass, and I don't know how to get a proper connection back
try here and see if you can get any clues.

i don't know if it helps, but it might lead to something.
I used that guide when I first took her apart, and tellingly, they don't disconnect the screen from the frame.
