This is nothing special, other than regular soldering tool(low power) for this kind of stuff.

WARNING: when soldering, try to heat as less as possible lcd, overheating it, could lead to altered colours!:eek:

Anti-Static Grounding Wrist Strap is unnecessary?
[HD2 General] BrianXDA:
My screen is broke too :'( look at this
[HD2 General] daveyb123:
These aren't videos of a HD2 but they'll give you an idea. A soldering iron with variable temperature would be helpful - yo keep heat as low as possible, but not essential. Just practice lots first. Removing the old ribbon will probably be the most tricky part.

http://www.youtube.com/watch?v=R698z9QaypY

http://www.youtube.com/watch?v=NfzMOzuqNDQ

That'd be too much heat for me in the second video.

Re antistatic wristband.Yes, you should use one. You might get away with it, but you might not and brick your device. There's plenty of reports of people putting their device back together after fixing it to find other things don't work. That could be for various reasons, but static is a good contender. The tiny circuits in microchips blow like a fuse in a power surge from static you won't even feel is there. I've blown plenty of things before because I didn't use/have one. Static electricity measures in thousands of volts.
[HD2 General] DOVIZ:
Yeah, thanks for the videos, i will try to learn that as good as i can, just listen, i found some soldering iron, it's melting temperature is 190C, it is good or not? 1mm thick. I don't have soldering tool with variable temperature right now :(
[HD2 General] DOVIZ:
Got one soldering tool with variable temperature, but i have one more question, what soldering metal to use? Is at 230C temperature melting metal good? what electrical conductivity it should have? what about density?
[HD2 General] daveyb123:
Just buy some standard lead/tin solder with a flux (rosin) core like this http://www.ebay.co.uk/itm/63-37-Tin...Home_Garden_PowerTools_SM&hash=item43a8f0ecbf

230c is a bit high. Start at 190c and increase if need be. Note that leadless (silver/copper/tin) solder is harder to work with and it's not like you'll be doing a lot of soldering. Google some basic soldering guides as you're new to it. Note that metals melt at different temperatures. You'll only be melting the tin/lead solder which has quite a low melting point as metal goes. You don't need to think about conductivity and density, that's the solder develper's problem. What you can buy off the shelf/ebay will be fine unless you manage to find something really uncommon and strange.

hey guys, i found htc hd2 for less than 90 euros, only problem is touch, that sometime works sometime not, so what u think, is it good offer, considering that i will replace and buy new touch digitizer
[HD2 General] mengfei:
I'm selling mine for only $60 but only here in asia otherwise the buyer should shoulder the package. Since most people here in HK don't repair stuff so it becomes expensive to have it changed here.

screen just suddenly stopped & a friend opened it up for me to see if it was just a loose connection but confirmed it was the touch screen :crying:
[HD2 General] AssFIT:
thanks for the search info.

Similar problems

I have replaced LCD+digitizer combos to about 10 HD2s and had similar problems with some. Either it won't turn on with back cover assembled or even more annoying just the LCD won't work with back cover, it just stays black. Without back cover everything works fine. In one case where the phone wouldn't turn on with the back cover assembled i noticed that the battery didn't quite fit in its slot in the back cover so i added a little sponge to the back cover to push battery towards the motherboard contacts and it worked. So far i haven't had any luck with that one phone where the LCD won't work with bc (back cover) assembled. Everything else works fine, including touch, but LCD stays black. I have tried everything i can think of, including resoldering the IC below the reset button but it didn't help. Anyone else having same kind of problems? Any ideas what could help? I have tried 4 LCD+digitizer assemblies already and they all have the same problem with this phone, works fine on other phones. I have tried replacing the bc also but it didn't help.
[HD2 General] hitman1376:
good Info ...

Great Thanks My Friend ... I Replaced It With No Problem ... Thanks
[HD2 General] lebmb:
i think it might be to let the phone know when the battery door is open

im gona buy this one if i dont find something i can use at radio shack

http://cgi.ebay.com/3M-TAPE-ADHESIV...-TOUCHSCREEN-/170429785461?pt=PDA_Accessories

cuz i really dont feel like waiting for it to ship from half way across the world
[HD2 General] lerameur:
Hi,

What kind of glue have you used to assemble the digitizer and the screen?

And what kind of scotch you used next?

I think i'll use the "3M TAPE ADHESIVE"

Thanks
[HD2 General] chhada:
Can you direct me what type of tap or glue did you use to put all the part back together?? thank u
[HD2 General] OfficeLinebacker:
It's been said before and I'll repeat it: the same stuff that's used to glue iPhone glass/digitizers to the frame. You can get it, then cut it into strips with a razor.
[HD2 General] wendellc:
Office Linebacker, thanks for that tip. Exactly what I did:D
[HD2 General] lvrijn:
I also replaced it.

The frame back to the LCM can be done with 3M adhesive.

But that isn't as strong as the original double sided tape..
[HD2 General] lovetv:
Alright I just broke my HTC HD2 :(:(:(
[HD2 General] OfficeLinebacker:
Well you are definitely in the right place. Are you handy with small, delicate things?
[HD2 General] william-johnson:
Nice to know that I (like lovetv) have also come to the right place as I just broke my Screen. Everything works perfectly well but the screen is cracked in the top right corner. Kinda takes out the beauty of the device.

I am wondering if anyone can point me in the right direction to buy a replacement screen. I have read there are two types of Screen/Lcd replacements: USB and Solder. Now my Device is a T-Mobile UK device but does NOT have T-Mobile branded anywhere on the screen. does anyone know what type of replacement screen I need to buy? (Not sure reading from the 1st quote above). I am thinking to replace this by DIY or worst case, buy the replacement part and take to a phone shop... might save some £s.. :) anyone knows if this would be compatible?

I found just the outer glass for the hd2 for sale on ebay without the digitizer.

Is there a way to remove the outer glass and place the new one on without completely disassembling the phone? since my touch screen still has full functionality.
[HD2 General] keithsipa:
There are only 2 major parts for the display on the HD2, the digitizer and the LCD. The "outer glass" is the digitizer, if the ebay listing you are looking at does not know what they are selling, then move on. Yes, you can have a screen that is cracked with pieces falling out, and the digitizer still work.

No, there is no way of replacing anything in the display assembly without completely disassembling the phone. Well almost completed disassembling.
[HD2 General] keithsipa:
From reading this thread, it appears that the T-Mobile version sold in the UK is the T8585. So it would appear that you have the right idea with respect to the digitizer needed. It should be the solder in type.

As other people have said, I personally would recommend ordering the lcd and digitizer as a unit, pre soldered and glued together. There has been various reports of how hard it is to seperate the lcd and digitizer without damaging the lcd.

GL...
[HD2 General] kcirred10:
I know that much...but the listing has just the outer glass only and its pre-adhesived. There is no ribing cable on the glass. I would post a link but I can't for a few more post.

either way, i guess the better question would be could i remove my current digitizer from the broken outer glass instead of replacing the entire digitizer? I would much rather do this instead especially since the glass is only $4 vs. $47 for the glass and digitizer.
[HD2 General] dragonfist357:
Where did he find these videos? I would like to see them for all HTC devices.
[HD2 General] OfficeLinebacker:
There is no practical way of replacing JUST the glass.
[HD2 General] Ahil:
60H00295-00P vs. 60H00300-00P

Is it possible to replace a standard screen - (60H00295-00P - soldered digitizer connection) with the 60H00300-00P LCD/digitizer module (latter being the one which uses a lifting ribbon connection, ie non soldered).

Or are the dimensions of the two screens different?
[HD2 General] OfficeLinebacker:
I think the dimensions are slightly different, but only enough to cause a little gap, but it will still fit.
[HD2 General] pablow:
My Digitizer died yesterday, and been looking on ebay for a new one, but there is a inconsistency as to which digitizer model is compatible with the t-mobile units, some say its the solder one and others, its the clip one, others say its the clip one but have the picture of the solder one (and say that the picture is accurate).

It seems most of them say that the t-mobile model has the digitizer which requires no solder, is this correct?
[HD2 General] keithsipa:
Yes, that is correct. You want the digitizer that says T-Mobile on it, and yes it will be the clip in type, no solder required.
[HD2 General] miketam818:
Hi new user here...

But I recently dropped my hd2 and I dont really understand the parts to buy.

The outside of the screen is not cracked, but the left part of the phone's screen is blacked out and I see colorful lines on the screen like the inside of the screen broke. Can anyone tell me what it is and which part to buy? Thx.
[HD2 General] hd2life:
I cant find t-5 anywhere in my town, can i use torx t-6 to open HD2?
[HD2 General] OfficeLinebacker:
In your town? Where do you live? If you can order a digitizer from ebay, you can order a T5 too, tool
[HD2 General] hd2life:
I could order yes but it would take weeks to arrive, i found torx t6 in one shop so it wont do?
[HD2 General] jeet92:
xacto knife works wonders. I did it yesterday and it was amazing at cutting the glue.
[HD2 General] hd2life:
When ordering lcd + digitizer do all versions fit T-mobile HD2 or is there a special version. I am asking this because it's impossible to find a t-mobile one, most of them are for Euro HD2.
[HD2 General] Axel85:
I will never change only my touch panel...too work and then is really difficult to havo no dust or adhesive on lcd panel.And i m very good at soldering since i mod consoles and i m an electronic/informatic tecnichian.Form me it s better to buy one new from factory touch+lcd,i tried to do something like this to my old phone and everytime dust enter in the screen.I want a perfect screen view :p
[HD2 General] theroffness:
No, it does not matter which lcd + digitizer combo you get. All versions are the same dimensions.
[HD2 General] baco200:
I tried to replace the lcd + touch. I bought the soldered combination to be safe. The assembly went almost perfect but after starting the phone the volume buttons don't work. The question is......??? What to do...???
[HD2 General] Jouke:
Probably ripped the volume flex.

Disassemble the phone again and see if volume flex isnt ripped.
[HD2 General] baco200:
Is there a way to flash a ROM or radio without the volume buttons? And enter bootloader.
[HD2 General] tom011:
Hi, the digitizer of my leo was broken, so i replaced it with a new digitizer glas. The assembly went almost perfect after starting the phone the background light of the display and the buttons light up, it vibrates and it sounds like booting. When i push the volume button it confirms also with a sound. When i connect it to the pc i can access all my data. But the display shows only the white screen and nothing else.

What can be wrong? Can anyone help me?
[HD2 General] OfficeLinebacker:
You probably cracked the display in the process of fixing it.
[HD2 General] kampf:
If you are going back to stock, you don't need a working display at all or any buttons if you do it from Windows Device Center in Vista or 7.

I returned my Leo back to stock and updated it to the latest T-Mo WM version yesterday.
[HD2 General] tom011:
No, there are no cracks on the display. When the display was broken, then i ought to see funny colors, right? But the display shows only a complete white screen. My guess is that the display does not get any information.
[HD2 General] OfficeLinebacker:
A broken display can take on many guises and being completely white is one of them.

Sure a cable could be loose, too.
[HD2 General] zeba5:
Hi i have a couple of questions after i saw the official dissembling and assembling videos.

In the assembling video the cute voice tells you to "paste a mylar" what's that ?? is that important ? does that mylar comes with the phone ? (i mean, should it be there when i dissamble the phone so i can put it back during the assembling process).

Also, kinda same question with "place a gasket" (min 6:34) .

I hope you can understand my concerns, i'm going to fix my phone today and i want to make sure of everything.
[HD2 General] Petran911:
Hi guys,

One week ago, my HD2 fell hardly and the screen was smashed. I ordered a replacement and I tried to do the change. It is very hard for a person not acquainted with mob maintenance. I did all the steps but I am afraid that either: 1) haven't soldered something or 2) broke something in the process. The screen of course is not fitting into the chassis and this is the result I am getting:

Can tou please let me knowwhat I should check for or is it the time to buy a new one;:(
[HD2 General] OfficeLinebacker:
I think what has happened there is that the display was damaged. So you will want to re-do it with the LCD-digitizer combo.
[HD2 General] lvrijn:
Yes.

Still not understand why people want to replace only the digitizer.

Just take the easy way and replace the combo..
[HD2 General] OfficeLinebacker:
Because the part to repair the cell phone is MUCH cheaper.

You pay for it with way more dangerous and complicated labor, but many people have more time than money.
[HD2 General] emanrod:
so im guessing i will need a solder.......dang it!
[HD2 General] zeba5:
hey guys i have replaced the screen but now only the backlight works. The phone turns on but it doesnt show anything. I can see that the backlight of the screen is on but nothing else.
[HD2 General] OfficeLinebacker:
You probably damaged the LCD. There's a small chance it's a connector.
[HD2 General] mZimm:
Cracked my HD2 screen today...I've repaired phones before and don't generally have a problem but before doing this I just want to make sure I'm getting the right thing. I have the TMO-US version and my phone works fine it jus thas a big crack in the glass. If I get the digitizer and screen then I don't need to do any soldering or mess with separating/attaching the glass and digitizer and it is just a matte of replacing the screen, correct? Would this do the trick for me?
[HD2 General] hypertyper:
The link you posted is just for the digitizer without screen. Anything with screen has "a big black thing" in the background rather than being see through.
[HD2 General] inode86:
Just broke the glass on my screen :( The touch still works but you tend to get glass stuck in your finger haha.

I bought this replacement http://cgi.ebay.ca/ws/eBayISAPI.dll?ViewItem&item=310245339759

I think I might be best to get a professional to replace the digitizer for me though. As I am no good with soldering and that video makes me uncomfortable with the whole process.

I wonder how much someone would charge since I already have the screen..
[HD2 General] cz373298624:
That looks a LOT harder than an iPhone.

ESD Wrist Strap

Hey Guys

the screen of my hd2 is broken :(

Now i bought an digitizer + glas screen + tools

In the video they are using an ESD Wrist Strap for preventing

electric shocks to the devices. Do you have any hints for me how

I can prevent such a damage without having an ESD Wrist Strap?

Thanks a lot for your help :)
[HD2 General] hackwell:
I had to replace the dead LCD display on my HD2 and I had A LOT of fun !

The harder part is to separate the LCD from the digitizer without damaging it. Almost impossible IMHO.

In that case no problem , the LCD was already dead ! So I destroyed it to save the digitizer.

Then came the reassembling part... How do you place correctly the one on the other so the combo will perfectly fit?

The 3M 2 mm adhesive from Ebay is mandatory , never use a thinner one or you will have a huge stain in the center due to some contact between screen an digitizer that stick together ... Remember : it is very hard to separate them again ! And use antistatic spray to clean both parts...

Don't use thin adhesive neither to reassemble the combo and the inner chassis : the digitizer will be too close and will press on the keyboard and... won't fit perfectly!!

I finally have to order another LCD as I scratched it while trying to get rid of the center screen stain.

The cost begins to rocket skyward :(

So I think the full combo solution is the best
[HD2 General] mZimm:
Having worked on electronics numerous times, the ESD strap is not a requirement. Just make sure that you touch something metal that is grounded prior to working inside it and you'll be fine. I'd also recommend plastic tools whenever possible. I've never used a strap and have never shorted out any computer or phone components.

I decided to go the digitizer-only route because the difference in price is so big and my LCD is still fine. So I'm going to need to separate the two parts when I get my new digitizer. My question is in regards to the reattaching...what adhesive to use? Some links were posted earlier in the thread but are too old to still be active. Somebody said that the same thing used to replace the digitizer on an iPhone is what we need - so will this work alright if I just cut strips for the two sides of the HD2?
[HD2 General] hypertyper:
What you posted should work fine. I used cheap standard double sided tape and cut it to size with a sharp knife and it worked out fine. If I were to do it again I would make sure though I get some 3M branded tape though. There is 2MM tape floating around ebay I think which might be worth investing into. I tried to get something from a local shop because I didn't want to wait and it turned out to be crap. The link you posted seems like it could be cheaper. I got three sticker sets (cut into shape for iphone) for £1. Just have a look around ebay.

I posted some more general info in my thread here about my experience:

[HD2 General] wizzbang3:
I also smashed mine today, I've ordered a digitizer for 30$ and I'm going to try it (plus 5$ tape) I'm fairly good with stuff but the videos for this are AMAZINGLY complex....... Ithink a lot of patience and care will be required.

It will be a fun weekend experiment.
[HD2 General] GnatGoSplat:
I bought an HD2 with a cracked digitizer. I didn't realize these things were so much more painful to take apart than other HTC phones and iPhones or I may have avoided it!

Anyway, I'm not sure why iFixit and these videos have you disassemble all the circuit boards and stuff. I found no reason for that. Just remove the chassis from the housing, partially detach the black tape on the sides where it is sticking to the chassis, then slide a credit card between the LCD assembly and chassis to cut through the adhesive tape, being sure not to go too deep on the lower right (with LCD facing you) so you don't damage the flex. Then lift up on the left side of the LCD and detach the flex cable from the logic board. Last step is just to disconnect the button flex and remove the 3 remaining silver screws holding the bottom logic board in to where it is loose, then the LCD assembly flex can be removed. This job wouldn't be bad at all if you are replacing a complete LCD+digitizer assembly, but I will try replacing just the digitizer by itself to save $50 which might be a nightmare, especially in dust avoidance.

Did anyone ever confirm whether or not the Euro LCD+digitizer assembly will work in a T-Mobile USA phone?

Thanks, i followed task and replaced my non-response touch screen. Now my hd2 back to normal. :)

Hi there.

Where do I find out (exept for disasembleying the phone) what kind of a screen i have. I tried to google the P/N, but all I get is nonsense. Is it only the T-mobile that has the non soldering LCD? May be some of you guys could see this from the PN?

hello

i have an htc hd2 international version i thought the digitizer would be wielding kind but it is the plug-in type P\N 60H00300

so can i use the t-mobile digitizer with it or what should i do

thanks in advance
[HD2 General] GnatGoSplat:
None that I've found. I just saw one of the comments on the vid said you don't have to remove everything, and that made me decide to more closely examine how the phone is put together and I confirmed that commenter was correct.

I did post a pic showing what I did to remove the LCD from the frame in this post:

http://xdaforums.com/showpost.php?p=16718344&postcount=16

Maybe it will help? The pic shows after I'd cut all the adhesive tape, I was able to lift up and as you can see the flex is in the corner, ready to be unplugged from the lower circuit board. Basically, I cut through all the adhesive under the LCD/digitizer assembly, being careful not to cut very deep where the flex cable is so as not to damage it. Then lift up the LCD on the end opposite of the cable enough to get some small tools in there to disconnect the flex from the main circuit board. Afterwards, remove the lower circuit board screws to loosen it from the frame enough to pull the flex out of the connector. Reattaching the flex cable into the connector is a little more challenging as you'll have to kind of massage it back in, but still pretty easy.
[HD2 General] exiva:
When you buy the fullscreen replacements on eBay, they don't come with adhesive on the backs to stick to the midframe. What kind of tape should I use to stick it on so it won't come off? Looking for something near factory. I don't want my screen to fall off one day lol.
