[Q] hd2 digitizers/LCD

Hi ya maties,
iv picked up a hd2 that turns on but no touch screen nor the buttons on the bottom work,
so i took it apart and first off, noticed that there was sticky tape on the digitizer,
and realized someone has tried to fix this, what my question is, i have included a photo of the back of the LCD screen and the connecter to the digitizer,
am i right in thinking that who ever tried to fix this, irst, didnt know what they were doing, and secondly didnt buy the right LCD / digitizer combo, as i have found out that there are two diff digitizers and lcds? anyways any insight would be great, as this i think is a pretty straight fix,
Cheers
Oliver

I happen to be going thru an lcd/digitizer replacement myself. It looks like the previous owner did in fact get a mismatched lcd digitizer combo. The digitizer in that photo is the European weld on type, and will need to be soldered to a matching lcd. The lcd in that pic is the American version and needs only to make the ribbon connection.
Cheers

hey thanks for that, i thought i was going crazy when i couldnt find out what the clip on the back of the lcd was for, the idiot who tried fixing it used sticky tape to stick it to the back of the lcd in hopes of it working. lol, anyways the other thing is the membrain for the buttons at the bottom are broken, is there a web site that sells the membrian?
cheers

Your best bet would be to look on eBay for a broken hd2 for parts
Sent from my HTC HD2 using XDA App

i actually have an lcd and digitizer screen that I may let go at a good price..not to mention 2 phones worth of misc parts/mother board, chassis, etc...
let me know

Do you guys know if you can swap in a AU Telstra HD2 (T9193) main board into a US TMO HD2 (T8585) digitizer and shell? My digitizer quit and I want to get up and running asap.

Anyone know?

[Q] hd2 flex cable

Hello , my volume buttons have stopped working , i have opened it and seen that i need a new flex cable , my hd2 version is tmous 1024mb , on ebay i only have seen T8585 flex cable.
It will be good for my model? because i havent seen different flex for my model anywhere and i think it will be good. Just need to be sure. Sorry for my bad english

i think they use same cables but i'm not sure.just google it

Found nothing on google. Anyone can help with this. i think i will order it , because i cannot found flex for tmous.

Wait! They don't use the same flex cables, the Euro and Tmous versions have different motherboards, cases and flex cables! I work on them ALL THE TIME.

They USE THE SAME flexes!!! I have both Tmo and EU versions, all cables are compatible (bottom buttons, main flex cable, LCM), I've tested all of them. Yes, MoBo of TMo is a little bigger and wont fit in an EU housing, but all connectors are absolutely the same in both phones.

Anyone else please comment, because I need new flex for t-mobile version.
so flex is the same between 2 versions?
Second, anyone have any good tips on how to separate lcd and digitizer without breaking lcd?
because everytime I try to separate lcd from digitizer from touch pro2 they break!!
is the hd2 the same? glue together?

OMG! He doesn't believe me!
These cables have the same contacts and more of that, the same P/N: 50H10116-01M.
I changed one broken in T-mobile model with one from EU HD2 version and it works as needed, camera, BT, WIFI, all as with the original cable.
Other alternative is to solder broken connections if you have eagle eyes

Did you heated LCM to 60*C before separating them? And YES, in EU version digitizer and LCD also are sticked together with double-sided scotch-like adhesive which looses most of it's stickiness at 60-63*C and digitizer may be separated with thin plastic sheet, I use a half of credit card (they can be very easily separated in two thin sheets).

The connectors are the same but there are two different part numbers. I always replace with the correct one so I suppose maybe they are the same size. However many times there can be small changes involved the people are not aware of. A manufacturer I deal with on these has 2 different numbers and has strict writing of which one to use with which phone. So for me, it wasn't worth using a Euro flex on a Tmous HD2 when they are similar in price.

Can you give me a link where to buy usa hd2 flex cable?

You did not understand, I did not checked only connectors, I've installed in a TMo HD2 main flex from European version, works perfect, just as the original one. If You want, you can replace only "correct one" but I wrote in my post for those who can buy main flex only for EU version because of shipping limitations or for about 20$ less in price (I didn't found main flex for TMo less than 64$ and for EU version price is 42-43$).
Just for knowledge, It can be repaired if you are able to handle an soldering iron with micro-tip and have a 20x magnifying glass. It will loose it's shining look, of course, but who will see it without opening the phone

How fragile is the Flex cable for the bottom buttons? I've got a HD2 with a broken digitizer that I replaced but the bottom buttons don't work anymore and neither do the lights on it, it was working before I took it apart and I have been careful with it. Same thing happened on another HD2 I tried to fix.
Also the ribbon cable for the LCD screen is very hard to connect again because of the tight angle it bends and goes in and the tab on the connector that locks the cable doesnt seem to lock it properly and the colur looks slightly faded unless I put pressure on it which makes it work normally.
Any ideas?

the connector is pretty fragile and there is a high wire density on that small flex cable tip. I were in your situation yesterday, managed to get the buttons working after some 8 tries at reconnecting that flex cable to the motherboard. Try to insert it as deep as you can get it and try to secure it tightly.
The display connector is fairly easy to connect, i make my connections while keeping the display tilted at about 90 degrees from the mainboard.
Don't worry about that, it isn't the baddest situation you can get (try doing the same thing on a htc herald or some older querty keyboard eten's .. that's a real hell)
ontopic.. ah yes, the flex cables are 100% compatible, one of my tmous hd2's has an eu flex cable. It's working just fine. Electronically speaking.. they contain 100% same components.

Right.
LCD screens are different bu you can change them only if you change as an assembly of digitizer-lcd.
housing, chasis and mother boards are different, the rest can be exchanged.

[Q] Which digitizer for my HD2 and where from?

I've successfully taken my HD2 apart now I'm not sure about the digitizer I need. My phone doesn't have a T-Mobile logo and it came with the leather pouch which I read means it's not the T-M version.
I'm looking for a new digitizer and the one that looks like the connector would fit says it's for the T-M version. Rather than go on about it here is a pic of my digitizer. I'm in the UK so if anybody has shopping suggestions I'd be grateful.

I can't say too much based from picture posted above ...
It could have already replaced unbranded digitizer or it's Telstra, European, Taiwanese version... Are the call and end buttons colored on your phone (green and red respectively)?
If You have enough money, about 89-120$, better choice will be to buy a LCD+digitizer assembly also named LCM, they will work at all versions of HD2, not only T-mobile or European, I tested the LCM from European HD2 with in a T-mobile version of HD2 ant it works perfect. So go on eBay.com and buy one

Call buttons are all grey. I've though about getting the whole combo but it's more than twice the price and I'm not exactly rich so it would have been nice to just get a digitizer. I was hoping there would a way to identify properly which digitizer I need. I've sent a message to one of the suppliers on ebay. I'll see what comes out of it.
According to this article the different versions of the HD2 aren't physically the same size in terms of casing. Do the LCM units fit all the same?

Let me help you:
#1.your picture is defining an uncommon/unbranded TMO(bile)US touchscreen(No doubt about, at least for me!), but grey hardware keys are for international HD2 model, probably you have a (let say) hybrid (home made)version between american(TMOUS) and international model;
#2.nevertheless, in your financial position, I'll look on ebay for an appropriate touchscreen model(there are plenty, most of them with very clear pictures like your's) for about US$30-40;
#3. if you want a combo, as far as I know(and pvii already said it) the 2 LCMs are geometrically identical, but the frame/chasis on which lay on the LCM is different(the american model is longer on 2,0-2,5mm);
#4. international model is cheaper & easier to find.
For more informations/help feel free to contact me!
Cheers!

May be it will be better if You post a photo of rear side of your display or at least say it's product number (from sticker on square copper pad, rear side), i.e. P/N:60H00300-00P is for T-Mobile and P/N:60H00295-00P is for international version.
If You don't have enough money for a european LCM combo, you can buy a LCD apart and digitizer apart, even from different sellers but you have to buy matching parts, both for European or both for T-Mobile version.

Thanks for the info guys. The serial number is the kind of solid identification that I was looking for. The serial on my screen ending in 300-00P indicates that it's the TMobile version.
My theory is that since this phone was bought when it wasn't exactly new on the market HTC had switched to the solderless screens which seem more modern?!?
I'm assuming that in terms of connection the digitisers that look like they will fit in terms of connection should work. I'm only worried about the dimensions of it since the casing of mine is smaller than the real TMobile version from what I can tell.
Since I can't find anything else on ebay I guess I'll order one of the TMobile ones and see if it fits. I'll look for a shop with return policy just in case.
Thanks for the help. If anybody has further suggestions I'd love to hear them.

Read carefully my previous post:
you don't have to be worry, the touchscreen, lcd and lcm are geometrically (length x width) identical!

Yupp, any LCM will fit on any model of HD2.

I wasn't sure which part was identical but if the digitizers are then what I ordered should do the trick. Digitizer should arrive this week so hopefully I'll have something to report about
edit: Digitizer arrived and fits perfectly. I guess my phone was some weird mutation. Solution is to just buy a digitizer with the correct connection, job done.
Oh and getting the right tape is a total *****. I had to take everything apart again because my tape wasn't strong enough!

I thought I'd post my findings and produce some cliffnotes on how I fixed my HD2.
Firstly, if you search youtube for "leo as" and "leo dis" you will find the official HTC videos on how to assemble and dis-assemble the HD2. They make it look easier than it is. Also, they don't separate the digitizer from the screen.
I ordered the tools to "dis" off ebay. Especially the T5 screwdriver was worth getting since it allowed me to find out which digitizer I need. I have a non TMobile version but needed the TM digitizer.
I found that using an old credit card type of card works very well for taking the phone apart. It can reach further into the phone and bends rather than breaking like some of the cheap tools from ebay.
Especially for separating the digitizer and screen it's great. I heated up the digitizer & lcd combo in the oven for a couple of minutes like the video advertised for taking the middle part of the phone apart (you'll see in the vid). Here comes the interesting part: Instead of sliding the card / tool all the way across the screen (between screen and digi), it's enough to just separate it around the edges. There is no glue or adhesive in the middle. It seems obvious now but I got lots of glue all over the LCD which was a bit** to clean.
Another tip that is worth repeating is getting the cheap double sided tape from ebay which is meant for Iphone digitizers (3M branded). I got three of them for £1 incl delivery. I used it to put the "middle" of the phone together. Screen and digi I did with cheap double sided tape which is working but I regret somewhat.
Another tip would be the whit cable (flash?) which goes on the bottom of the mainboard. I put it on top to start with. It's easy to mix up. Also it makes sense to put one end on before you put down the mainboard because that way you still have proper access.
Make sure you have good tape and be patient. I had crap tape and just slammed things together because I was so keen to see if the phone still works. I had to take it all apart again which almost broke the phone because it was coming apart in all sorts of places.
Overall it's like a big, fragile puzzle. I got the phone from a family member who had dropped it so all I had to get was the digitizer and tape. Now I have the best phone that ever lived
If anybody has questions, I feel like I know the hardware of the HD2 inside out.

I also took mine apart to replace the digitizer. I haven't got the new one yet though. I also watched the take apart vid on youtube. Unlike you I didn't disconnect the white wire from under the board. As a matter of fact, I left the other wires attached to the mainboard and just disconnected them from the GPS, camera and Bluetooth boards. At the end of the little channel that the wires are in, there was a little metal tab that held the wires in place. I just bent the tab up to remove the wires. Like you I used a piece of credit card to loosen the glued pieces.

[Q] Broken screen

Hi,
I stepped on my HTC HD2 (European version) and now the screen is broken. Actually the glass istself is fine, it's something underneath it. First some black spots appeared, then they started spreading around the screen perimeter. (See attached images).
My question is what do I need to replace? The whole package? The glass? LCD screen? Digitaliser? Or are they all same thing?
Thank You.

LCD is cracked.
LCD & Digitizer glass are bonded together & can be separated.
Normal scenario is dead digitizer & removal of delicate LCD can be difficult, as you are saving Digitizer you should be OK ! take extreme care of all ribbon cables ...
You can buy these 2 parts already assembled or individually.
Worth also noting that the HD" EU model & USA T-Mobile screens & connector are not the same so do research before committing on parts purchase.
T-Mobile USA is easier to repair as has socket connector but EU version has solder connector.
Looking a photo you have EU version ...

So all I need is this part HTC Touch HD2 T8585 LCD?
P.S. Screen is fully responsive, just the black dots...

assuming you dismantle & assemble it without damaging any ribbon cables.
Most people seem to have issues with button/digitizer ribbon due to bad handling ...
also connector soldering is required if buying LCD part separate ...
Black/greenish oily dots are LCD fluid I expect.

Had the same problem with my old phone. After checking with a repair service, it was actually cheaper to buy a new one on ebay instead of getting it repaired.

I know. I asked official HTC service in my country, ant they said it would cost 350$ So I'm thinking of buying broken part myself and find someone, who could fix it for less money. We'll see how it goes

The Cheapest Way is to fix your Cracked Displayproblem by yourself. You can use US und EU Touchscreen-Glases and LCD-Displays. HTC has two Versions: With Soldering ( the 295 Version ) and Click On without Soldering ( 300er Version 2 ). Both are Working in EU-Models perfect. I preffer the better 300er Version...
Now i´m working since a couple of days ( finished today the 1st quarter from my instuctions ) on my DO IT YOURSELF Web-Project and i will bring this forward the next few Days if i have a little Time. Here the Link:
mperlitsch.hintergrundbild.com/htc_hd2.htm
It´s complete in German ( because this is my Language and the Reason for my poor englisch here ), but i bet you can do that Step by Step when you look at my Pictures. Remember: It´s not finished yet, only 25%. I will write the whole Process to Change a complete "Touch-LCD Modul" and Parts ( Glas or LCD from 295er and 300er Version ). It´s really easy to separate the Module e.g. Glas from LCD ( i need 30 Sec. to do that without heating up only with a simple thin Guitar-Plec). The Only problem is to find the correct adhesive Sticker tape. The 3M Brands with 2mm is perfect to Tape the Glas and LCD together.
I recommend for every 1st Timer to buy a complete 300er Click On Touch/LCD Modul. It´s ready to use and a easy; fast and Cheap way. And if you destroy the Glas in 1-2 Years, you can Replace only the Glas without Soldering.
Best Regards and excuse my poor english,

HTC Leo screen replacement

Recently, my son dropped my HTC HD2(Europe/Greece version). The result was a broken screen. As I found out later, only the cover glass(digitizer) was broken and the LCD was OK.It even worked over the broken glass but it was dangerous to cut yourself anytime.
I looked in ebay and found a new digitizer at about $15. I also found a guide on youtube on how to open the HD2 and replace the digitizer. I followed all this steps (difficult and tricky but possible) just to find out that the ribbon cable of the old digitizer was welded(soldered) on the LCD. I found out after that, that there are 2 types of HD2. The one like mine and the (I think) T-mobile version which is with a connector.
I had no luck trying to mannually solder the ribbon cable on the LCD. I am not so good on that.
The next is to order a preassembled LCD with a digitizer. It costs about $40-$70 on ebay. It is a litle expensive, so I 'I try to keep it safe. Has anyone else experienced this situation? Are there different types of LCD as it is for the Digitizer?
Can anyone help me on making a corect decision?
Thank you

You should buy The T8585 model.
Don't worry if Tmobile is written on the screen.
