[Q] Some HD2 digitizer issues - HD2 General

Hey guys, a few weeks ago I had issues with the digitizer of my fellow HD2.
After reading a lot here and re-flashing my ROM I decided to replace the digitizer.
With grit, (very) professional tools, a few read posts here on XDA and an incomplete Guide from iFixit.com I managed to tear the HD2 apart and replace the old digitizer.
That did the Job, I was able to operate the device again (the touch wasn't working anymore).
But today, it appeared that the touch won't work when I press the powerbutton in standby.
I'd appreciate a little help here, what's wrong with my trusty (3 or 4 year old) HD2?
Any ideas what to do?
I hope it doesn't hurt that much to read my english.

Maybe bad digitizer or perhaps ribbon connection in socket not good or locking bar not latched correctly or broken! but also could be issue with the button board & hopefully it is as cheap & less of a job to do really. Had similar issue with a sticking button on one of my works HD2 handsets & it would loose touch until become unstuck & full cure was new button board ...

Thank you Mister B.
Maybe I just depleted (if that's the right word) the good ol' HD2. Promised it to my girl.
However, I think I can exclude a defect ribbon cable or unlocked/broken connection socket.
I don't want to open the HD2 again, seems like I used a too professional tape to glue the Digitizer to the phone.
I guess a new button board would be woth the try.
Anybody else who got experience who this problematic?
I won't give up on my buddy, but is there a follower, despite the fact that no smartphone can step into the shoe's of the glorious HD2?
Or would this question be woth an own thread?

i accidentally got the button board's ribbon cut while messing with my disassembled hd2. not sure if that's the same kind of problematic. i feel ashamed
well, time to leave this hd2 in the closet for spare parts later if needed, and enjoy the screaming leo in my hands

Hey there gilbert 32, if it's just the button-board, 5 Euro-Bucks would be worth the try, if you ask me. I'll give the new button board a try for myself.
I cut a ribbon by myself when i extracted the old defect digitizer. That was before i figured out how to integrate the ribbon from the new digitizer.
It was a little bit tricky, the guide for dismantling the digitizer (from iFixit) wasn't complete.

well, for me atm, the second hd2 would not be any real use. beside saying "the only thing better than the hd2 is 2 hd2's"
i will probably leave it waiting as spare parts. mainboard and other stuff are pretty good. only missing lcd/digi and now buttons

HTC G1 Screen cracked (digitizer) - G1 Parts order

Hi,
I'm new to this forum so i'd like to say hello to everybody first
I have a g1 with the screen cracked. When I say the screen is cracked I mean that upper glass area; The lcd does not seem to be cracked in any way so there is no bleeding at all. Touch still works very well even in the cracked area.
I seem to have come across only 1 ebay auction that was selling a digitizer and everywere is absurdly expensive to buy. Any ideas where i can find one ? At 189$ i'm half way to buying a new phone tbh.
Also I saw in this forum that some people had the same problem and people told them that they would need to replace both lcd AND digitizer, however i clearly saw in the htc dream service manual that they are two separate parts with separate part numbers. Is there some particular reason for this ?
Just to clarify, can any tell me the order in which components are placed in the htc g1 ? Im assuming they are as follows:
Touch Screen Digitizer
LCD Screen
cover and hinge
in that order..Am I right in my assumption ?
Thanks,
Mewt
Bump. I would like to know as well.
Check it out:
This listing just got put up on eBay today. This guy has 50 digitizers for sale:
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&ssPageName=STRK:MEWAX:IT&item=230336383436
If you are sure the LCD is intact, you should just buy the Digitizer. The LCD can easily be seen by opening up the phone.
http://cgi.ebay.com/HTC-T-MOBILE-GO...5|66:2|65:12|39:1|240:1318|301:1|293:1|294:50
I can confirm you can replace the digitizer WITHOUT replacing the lcd.
I just did it. A car ran over my G1 a while ago and I've been lurking on ebay ever since waiting for digitizers to be listed. With a new digitizer, a Torx screwdriver and about an hour I have just replaced the broken one and the new one works perfectly.
Of course that also means I now have a spare G1 since I bought another one in case I couldn't get a replacement.
I will be doing the same shortly.
Actually this is the best price I have found on a digitizer
http://www.perfectesell.com/gog1glscdico.html
Any tips on replacing the part? Does the phone have to come completely apart?
I can't buy from that buyer as he doesn't ship to Malta but thanks, now I know what I need to look for and will be doing so. Hope I can get my g1 working well again...I just hate trying to read messages with cracks in them
Thanks all for your replies
Its quite fiddly but as long as you have the manual you should be okay.
There's a few things tho. Page 23 doesn't really show you how to disconnect the camera very well. On the underside of the main board there is a connector like the one for the screen. It is released by flipping the paddle lever think 90 degrees down. Otherwise the camera connector gets pulled out when you remove the mainboard.
It should go without saying you don't need to disassemble the bottom "chin" part when you remove it. Oh and page 24 has an error, those aren't the 2 screws you need to remove, its 2 long ones, one is in the top right of that picture on page 24 the other is to the right of the one circled.

hey would you say the average person would be able to change the digitizer or do you have to be a handy man.. taking anybodys replys ONLY if you''ve done it
Well I guess I am the average person but then I've taken many a pc and laptop apart and put it back together again so maybe not...
There's nothing that requires great skill in it. As long as you're gentle, patient and careful (taking apart a G1 is like making love to a beautiful woman...). Keep track of what screws came from where and don't try and force anything.
Remember you need some torx head screwdrivers. but you can get these on ebay for very little.
I have to admit I feel a bit smug when I see forum posts from people who advise you sent it back to T-Mo and pay a $100+ excess for them to do it. As if!
Ah, my screen is just gently scratched, but it's annoying sometimes. I might look at into this if it gets any worse.
Just looking at the back of the screen when the G1 is open, it looks like I'd have to take the whole phone apart...are there guides I can look at?
Here is some sites that helped me out.
This is an easy to ready explanation to what you are looking at.

hey i have a question i replace my digitizer but now the bottom part of the touch screen... closest to the menu button doesnt work. what do you think can be wrong
Pull it apart again using the service guide section 2.2.3 and make sure all connections have complete contact. If something is not sitting right the circuit may not be ringing out correctly. Once you have gone through all the steps 2.3.2(lcm assembly) and everything looks connected properly, assemble, reboot and test. If it is not fixed you may have a bad digitizer I'm hoping for the fact that most of your screen is working its just a connection problem.

i'm willing to try replacing it myself as well and i was wondering how much your purchased your new digitizer for. would the one suggested earlier at this link: http://www.perfectesell.com/gog1glscdico.html be good? it seems a lot cheaper than other ones and i dont want to buy a faulty and cheap one that may not work as well or break. any other tips would be GREATLY appreciated.

Here's the correct page on the Perfectesell site:

Same price ($65) as the ebay auction that ended.
I dunno what that $12.95 thing was... price doesn't seem right for glass, touch sensing wizardry

Replace lcd screen or motherboard?? Maybe? Maybe not??

Ok this one goes out to all you cool smart guys out there. I currently have two mt4g's. One is working perfectly fine with the "bad screen", as they call it, and the other is bricked, or no it has a failed pu is what someone told me, but it has the "good screen".
Anyway while just minding my own business on the internet one day I came across a video which shows you how to replace a lcd screen in a mytouch 4G! I was hooked. I could do this I said, it looked so easy! Sure you need some patience, which I got btw. So I was determined to do this, even ordered the tools from repairsuniverse. So about the fourth time watching the tutorial I began to wonder if it would be possible to just swap motherboards instead of disassembling all the way to the screen. Mostly because I still need a heat gun so i could remove the digitized then lcd screen.
So i guess my question is will swapping motherboards solve the pu problem in the mytouch with the good screen? And while I got you here has anyone ever replaced there lcd screen?? Is it worth it??

Yes, if you put the good motherboard in the case with good LCD, you'll get one good phone.
Thanks for the response! This will make the job so much easier
repair options
sorry to piggyback you post but i had a similar question....
a friend of mine is giving me their broken mytouch 4g. it was working perfect but then she dropped it on her kitchen tile (bottom right corner hit i'm told) and now it will not turn on at all.....no cracks or anything, just a scratch in the corner. she says she tried a new battery and tried plugging into AC but no lights, nothing.
i've taken apart enough phones so once I get it i'm not afraid to do some swapping of parts.
my question is, those of you who have worked on this model, any indication where you think would be the problem? i'm hoping the lcd/digitizer is fine since its not cracked but we'll see....and i figured maybe i would just need to do a motherboard swap worst case? is there any other components you think could be shot after the drop? from what i've been able to find its just the 1 main mother board , correct? (meaning there is not 2 parts)
thought MAYBE i'll get lucky after opening it up, and verifying all the cables that possible some cables got jarred loose and thats why it wont respond but not holding my breathe on that.
thanks for the help!

Question about HD2 screen and digitizer change

Hello,
i cracked my HD2 screen (digitizer), i purchased new one, but the cracked one was working and i was not in a hurry to change it. After a minor drop, the LCD touch screen cracked under the cracked digitizer and now i have black screen...
Now also i have to purchase LCD screen, but i saw that there is ready to use screen+digitizer(and of course more expensive than screen and digitizer alone) .
My question is - what will be easier to change - ready to use digitizer + screen, screen and digitizer alone or there is no difference. I'm asking this, because I'm wondering should i sell the digitizer (if i can) and buy the ready to use screen+digitizer, or to purchase the screen and to use it with the already received digitizer.
If you can afford it you have to go with the all in one. Too much can go wrong during assembly and you should avoid it if you can.
yup, separating and installing them separately is a pain in the arse, its always better to do it in the one job if you can afford the initial high cost. My LCD panel needs replaced due to light bleeding, but I cant be arsed, the digitiser is likely to fail in the future anyway being an HD2 so ill wait and just do the two of them together.
OK, thank you.
I've watched 2 or 3 "how to change digitizer" videos. Is there a video for changing the lcd+digitizer or its the same as the digitizer change? I have to disassemble the whole phone to change the digitizer...

there is a vid somewhere, ill have a look later, but essentially yes. you need to remove the whole lot, the only difference between doing them both and doing them separately is that the two panels are stuck to each other, and its that process of separating or putting back together that's really tricky and people have ended up damaging one or the other trying it.
What about the difference in the EU and T-Mobile versions, like in the digitizer (soldering and insertion) Is there a difference too, if i take the whole "pack" (LCD + Digitizer) and what should i look for if there is a difference?

If you buy combo(LCD+digitizer) there's no problem to replace it to whatever version of HD2 you own: combo is interchangeable on both versions!
OK, Thank you!
I'm asking because i asked some buyers on ebay, and they told me "Sorry, my friend, but this is for T-mobile version" But on the pictures, they are all the same.
I had my EU hd2 digitizer changed too when it was broken, and when it was changed to a tmous replacement, they couldn't get the promixity sensor working.
Now I dunno if that's a defect from the screen or because it's a incompatility problem, but a further gsensor-working-in-wm6-but-not-in-android-problem in my other replacement mashup hd2 hybrid EUTMOUS frankenstein phone suggests that some parts may not be interchangeable.
You should just make sure that it's a EU digitizer so you won't run into further problems.

But on a already assembled combo pack (LCD + digitizer) how to know if the digitizer is EU version, beside the T-mobile logo.

Let me clarify that; my hd2 EU first had its digitizer+LCD replaced with a TMOUS version, and the proximity sensor stopped working,
then the the mobo was replaced by a tmous mobo in the same EU housing and the accelerometer and magnetometer does not work properly (accelerometer works in wm6.5 but not android), but the proximity sensor worked.
It's not just me having a hardware replacement problem, there's a significant amount of posts by other users about replacement parts not working properly. So everyone should be at least very cautious about using them because replacing with other parts may cause other problems.
my buddys HD2's touch screen suddenly stopped working.
he gave me the phone for $50.
i guess ima have to do lil work

Both versions are OK, but I would choose the first one.
There's no need for soldering(vers. 2): it's more like a packaging thing in order to get it mounted on chassis.

I guess its because you/they lost the little glasses that connect the display and the sensor.
Its easy to loose them as they fall out after you take the screen from the housing.
I lost them a few seconds ago and think that i know what wont work when i reassemble
@topic
there is generally no problem removing display from touchscrren. just make it hot with a fan or oven ~80°C is okay. and with a flat knive or iron-wire go for the glue.
If you do this you need new glue-tape. Mostly you get this from china very cheap but takes a while.
If your screen is broken now i would recommend to take a combi pack as you have no glueing, no alignment problems and so on.
its not very hard but kills some time and nerves ;D
OK, so lets do a round up, before i make the purcahse, so I'm sure i will make the right choice.
I'm going to buy this one http://www.ebay.com/itm/LCD-and-DIG...ccessories&hash=item43adebdc7d#ht_3076wt_1110
because its already assembled and much easier to use and IT WILL FIX on my EU version of the phone (Not US T-Mobile)
Only YES or NO will be enough

The Eu-HD2 is soldered isnt it? This version, from the picture, is the pluged version....
Im not sure because if you change the display also the connector type could be irrelevant.
But if this is the screen from Tmous-HD2, i remember that it was a bit bigger? Is it just the housing or also the display?
=>
Dont buy before this is clear!
(i would open my hd2, look what connector type is inside and buy that one just to be sure...)
And some advise: Try to glue the flex cable from the touchscreen(the one that goes under the end call button reallly close to the display)
This could help to improve the life-span of the cable as its not flexed every time you push the button(try when you hold it in your hands by putting the buttons in the frame and push it, if it flexes the cable fix that!!!)
Otherwise the cable will break one day and the wires will disconnect=> typical problem of not responding touchscreen

HTC HD2 dissasemble help!

My screen of my HD2 had a pixel fault, it had a purple circle on the middle of the screen, so I decided to dissasemble it.
Well, the phone inside is very confusing, I looked at the screen part and I couldn't see anything.
I re assembled it, and it won't power on now.
Is a phone so sensible when I touch it inside its gonna die?
I successfuly changed the digitizer of my Wildfire S so I thought the HD2 wouldn't be a problem.
Is a phone so sensible when I touch it inside is the chance to kill the phone 90% or what?
I need quick answers.
Thanks!

Hd2 is delicate & not easy to dismantle without experience & extreme care.
Most first time strip-downs by people with little or no experience result in problems like yours.
Check out the threads on dismantling guides & also videos can be found on youtube.
Check all connectors to mainboard are inserted correctly & also check basics such as battery pins are straight & not misaligned during dismantling/rebuild.
Initial screen issue sounds like lcd/digitizer needs replacing.
The very tiny camera holder on the Main Board broke, its Not a important thing its Theres thereby the camera stays at place.
While taking off the screen i accidenty broke the screen BUT ITS ALMOST INVISIBLE.
I lost some screews and the chassis won't fit in the houses.
I was going to fast cause I'm 14 and my parents didn't allow me and I didnt want them to see it.
But problem is, i lost the cable adapter for the phone vibrator (LOL)
And i lost the board screews so I used the screews of the phone case.
Where can I get new screews?

Pixel 4 - Need Replacement Motherboard

Hi all, was replacing my cracked screen and managed to graze some of the resistors on the motherboard and its possible one was unseated.
New screen and old screen both turn on but the touch does not register. I think I need a new motherboard.
Does anyone know where to get motherboard parts? Does anyone have one for sale as i would love to put this thing back together!
A more likely culprit is that the digitizer wasn't plugged back in properly . I would suggest that you take the phone apart again and make sure all of the connections are seated properly.
I've had a phone with motherboard issues and they generally completely stop working (black screen, no boot, etc). That's why I really don't think the touch screen issue is a result of a loose component on the mother board. That being said, if you really feel like it is a loose connection on the mother board, you can try baking the board in an oven to soften the solder joints which allows them to re-adhere when they cool down. Yes, it can actually work. Take the phone apart and stick just the motherboard (don't put the case, screen, battery, etc in the oven) in an oven at 400 degrees for about 10 minutes. I've always rested the motherboard on top of two wooden spoons that were sitting on a cookie sheet. This keeps the motherboard off the hot metal surface and allows the hot air to get to all parts of the mother board. Remove the motherboard and let it cool down before installing the board.
Thanks Sic for the reply. You made me not give up hope. I will try again and bake some mobo.
But which wire is the actual digitizer. Is it the one on the far right?
The rest seem to attach to bumpers or usbc charger. Thanks again for reply.
Attached 2 photos. 1 is my mobo with red circles around what i think was damaged. I think this is the only connection to the screen digitizer in the phone.
The second is from IFIXIT mobo. it looks a bit different, possibly different revision but showing the same angle. Digitizer connection on top.
Could one of those circles connections cause the digitizer to not pick up finger contact but the screen works perfectly?
Looking at the two pictures, I could be easily convinced that there isn't suppose to my any components where you have your red circles. If you look at the IFIXIT picture, there are three components, then a break, then 6 more components and another break. You red circles seem to correspond with the breaks in the IFIXIT image, although it is clear that the motherboard isn't identical in the two images. Just my two cents.

If you look at the IFIXIT picture, there are three components, then a break, then 6 more components and another break. You red circles seem to correspond with the breaks in the IFIXIT image, although it is clear that the motherboard isn't identical in the two images. Just my two cents.

Thanks for the reply.
Well, back to using my Pickle 3 which is still great and my Pixel 4 cupcakes are about ready. Let me check the oven.
Any update? I'm curious to know if baking the motherboard helped at all.

Update. Phone no longer boots after reinstalling everything.
I pre-heated to 200c ~ 400f and let it sit for 10 minutes and cool before reinstalling all the components. Was a final attempt I know.

That's too bad. I'm not all that surprised it didn't help, but I am surprised it actually made the problem worse.
Perhaps one of the components was loose and baking it made the connection fail completely. As I noted before, motherboard issues generally result in a no boot situation.
Baking it was a last ditch effort to try to get it to work, but don't feel like you have to quit now. You can try baking it again - perhaps for slightly longer this time. You have nothing to loose and perhaps it will cause a bad connection to re-solidify. Sorry I can't be of more help.
Hello I am sorry that your phone is not working. I was wondering if you do find a new board if you wanted to sell me your old mother board. I want to try a project of replacing the ram chip with a 16gb chip but to do so I need a old board.
Hello, I have the same problem, my pixel 4 XL got wet (I know, it was stupid) it reaches a depth of 2 meters, I opened it to myself if I could save it and it was completely rusty. and several transistors and chips came out. So I decided to look for a motherboard to repair it. anyone know where i can get the replacement? :crying: :crying: :crying:
