so my touch matrix cracked, got a replacement on ebay that looks perfect. i got it to work but everytime a do, a few days later it stops working until i fix it again. i can't seem to figure out how the flexible PCB connects to the back of the LCD module. it looks like HTC just puts a piece of tape over it.
however, i noticed when taking off the old LCD touch matrix that there was some sort of possibly conductive adhesive that made it very difficult to pull off. i got it off but one of the contacts got stuck on there and it i had to scrape it off with a scalpel.
see picture below for exact details. if anyone has any experience in doing this and getting it to work, please let me know, it's so frustrating not having touch on this phone.

I think you might need to have that professionally repaired. I used to refurbish phones for Motorola but I've never taken anything this advanced apart before. It sounds like you shouldn't have scraped off that conductive adhesive. The digitizer you bought should have been a relatively simple installation but you should have taken your time peeling off the old cracked digitizer. That adhesive is pretty strong and thats why they use it.
You might want to look into getting your hands on some of that adhesive and just replace it all. Sometimes the oils from your skin from handling such a sensitive ribbon cable could have damaged it as well.
P.S. Unfortunately, most of the people here are software genius's, not hardware experts unfortunately.
it's not too advanced. i figure if they at least offer the part as a replacement option on ebay it can't be too hard. and in the mass view, it's only 4 contacts and relatively easy to replace if you have a minor knowledge of electronics.
i keep taping it down firmly and even putting extra tape on top so that the pressure of the case will press down on the pcb to have a firmer connection.
note: i was very careful to observe ESD precautions, so that isn't it, plus there's no semiconductors that could be damaged in the touch matrix.

Hmm... have you tried good old fashion superglue? I mean not neccesarily putting it on the end of the cable where the conductors are, but on the cable right near the conductors to keep it from moving around and then placing a few strips of tape to sandwich the cable with the housing pressing it down tight?
yes i have but i fear what happens if when pressing it down if it gets on the pads, then i'm just totally screwed. it's a tough situation, i wish there was a contact at HTC that could tell me how it's done.
i'm going to also try contacting their support/repair office and see if they can provide any insight.

The superglue option is very risky but it could save your @$$ if you only put very little on the ribbon and then hold it in place untill it dries and then press down once the glue is already dry.
On another note, contacting their support office would probably be your best bet.
Everything you have done, even though not done wrong, it a far greater risk than I would have ever taken... I would have sent it in to be repaired of the digitizer had a crack in it or or the dot matrix got scratched. But thats me.
Unfortunately there aren't too many technicians here on this forum since it is almost completely firmware and not hardware here... Then again, there might be a few. Where I live it's kinda late at night so maybe they're sleeping or something. Lol.
i'm neither a hardware nor a software expertm but i may be able to help... i saw the manual somewhere... www.mdatweak.com/downloads/Wizard_Service_Manual.pdf... try that... maybe it'll help you...

Looking at the service manual, the screen and bezel can not be seperated, so i guess it is gonna be expensive i.e if you want to replace the bezel you will also get a new screen.
Suggest people ensure their phone is covered by insurance!
so do you think its easy to replace the screen and metal frame?
I am really considering to buy a dummy htc hd but before I do I just want make sure that if it is easy to do by myself

A dummy htc hd will probably not have a real screen and looking at the service manual, there appears to be no option to detach the screen from the bezel, however this comment is just based on observation and hopefully someone that has taken one apart can confirm.
I saw a discussion on the forum somewhere that the cost of a new screen was almost half the cost of the touch HD itself due to the fact that the bezel had to be replaced at the same time.
Thanks for the manual...
So... can anyone confirm the N. America frequencies that are listed in the manual on page 5?? Does this de-bunk the HTC twitter message??
Thanks for share!
Thanks at lot

I managed to detach the screen from the bezel, but it really was a hard peace of work. You have to stick a thin peace of plastic between the screen an the bezel and lever the display. You should be very careful due to the lcd display and the digitizer are glued together and you might get between the digitizer and the display and destroy it that way. The other thing you should'nt do is lervering the display on the bottom (where the usb connector is) due to the flatcable is located there and you will destroy it with the plastic tool.

I did replace the display from my TC very easily but on the HD I had hugh problems.
Did you manage to remov ethe antenna cover like in the manual? I don't seem to be able to remove it.
I ran over my phone with the car and I want to dismantle it to check what parts are broken.

Yes I did without destroying it, but I needed special tools. I used a very thin peace of metal. On page 20 from the dissembling manuel you can see the two square holes where the antenna cover is attached to the body.
Just go on and try it but be careful not to brake the little plastic clamps.

Hi all
My touchscreen is broken, the screen doesnt response on any touch.
Also there is a crack in the front glass what do i need to replace?
And how do i replace that?
Thanx Sander
It depends on what is exactly broken. However, there are whole Digitizer+LCD units on Ebay for about 70 Euros. Then you can find some guides here, which show how to replace the screen. But as it is glued to the housing, it is not that easy.
However, if you decide no to repair it, I would be interested to buy the faulty device, because I need a small part which got lost during my replacement process. So, in that case, let me know.
the LCD itself is ok.
Only the touch screen is broken
because it lay down on a hot light bulb
so its burned down
only the touch is broken and the cover is a crack in;D
Well the problem is, that both parts are glued together and I haven't found a guide yet which shows how to disassemble then. Even the service manual does not show it.
Check this video: http://vimeo.com/7623264
You can see that he also uses a whole unit consisting of both parts. You can watch the video and decide whether you want to try it or not. But it seems much more difficult than with some other devices as e.g. the Kaiser or the HD2 because more things are glued instead of being fixed by screws.
If you have the tools and the replacement LCD + Digitizer, its really not all that hard.
you only need the right torx & phillips screwdriver and tweesers.
the glue holding the parts in is no issue, its actually convenient as you can just press the new part in without re-gluing.
if you decide the follow the HTC service manual, you may like to checkout the link in the bottom of my signature, it points out all the crucial steps the manual will not tell you to do.
also, even if the LCD is good, replace it anyway, mine was good but my digitizer was bad and I replaced both at once, its worth any extra cost to get a preassembled LCD+Digitizer, if you read around you will come to the same conclusion, many on here tried changing the digitizer alone and failed. (many as in like 40+ people, strongly consider getting a premade lcd+digitizer)
I have successfully replaced the digitizer with a unit from Dealextreme that sadly was slightly damaged on arrival but in much better shape than the original.
However I have to say that it is extremely tedious work, especially separating the digitizer from the LCD.
The original glue is very strong, so just getting the LCD+digitizer out of the casing I found kind of risky.
I ended up using a piece of paper to cut the glue that joins LCD+digitizer, as a hard plastic or metallic tool would most certainly damage the LCD.
The whole operation took me 4+ hours, but it IS possible.

Good to see a success story!
I had only known of a phone repair technician who managed to peform a digitizer only repair, I heard that if you mildly warm the surface it makes it easier to separate, I'm still not game to do it, i noticed just how fragile the parts are when I replaced my bad digitizer with a preassembled LCD + digitizer, and Im still of the belief that its worth paying the difference to avoid the risk.
good stuff buskleif
i managed to seperate the digitiser from the lcd by steaming them apart, then fitting the rubber gasket to the new digitizer. it's a pain in the butt but very do-able. you have to take it very slowly and gently prize them apart as the steam is added. you can also get condensation on the backlight mirrored sheet but it evaporates and has no permanent issues that i've found so far.
I have an torn apart Samsung Vibrant.
I am no technician but have disassembled several other phones and found this is the hardest so far.
I leave you some pictures, it might help some one.

Let me know if you need some info, I will have to wait a few weeks until my new parts arrive so the phone it's going to stay that way...
Replacement Vibrant keyboard ribbon cable here...
So I got a Vibrant and promptly broke the display, I'm not sure how I did it, perhaps I sneezed too loudly or something, it doesn't matter - of course I'm going to fix it right? I repair electronics to board level, perhaps 25% of my time is spent on surface mount digital circuits, so I figure how hard can a cell phone be right?
Wrong! Oh so very wrong, grasshopper.
The digitizer and screen are held together with such veracity that I was afraid of breaking the plastic bezel piece around the screen as I pried the two apart. Even with help of a heat blanket (used for softening plastic electrical pipe for bending) I was unable to pry the two apart with any ease. I spent a couple hours over a couple of days only to finally separate the broken glass from the bezel and back plane only to find that I'd also torn the control cable from the keyboard assembly!
I've been looking for this little 5mm wide cable with 20+ flexible traces for a while now - here it is for $14! You have to but two but who really cares!
Look on globaldirectparts dot com under Samsung-T959 part# SMSNG6085870 Navigator-Flex-Cable.
Let me know if you want my extra cable assembly. I'll sell it to you for the same price I buy it for plus shipping to my house and then dropping it into a padded envelope and sending it to your house....can't be much.
Oh what a glory day!

Did you try to replace just the glass? I thought the glass was glued to the digitizer? And you have to replace them together. Kinda like the earlier iPhones. I thought anyway. ?
I cracked my Vibrant in the first month. Nice. Its in the corner so I cannot see it when the screen is on. But its just bad enough too ruin my resale value and Tmo wont swap it out becouse of physical damage. Nice again.

Vibrant Display Repair
The OLED display and the digitizer / face are a single assembly it's true. The two of them are sandwiched together and bonded with some sort of resin along the edges. This assembly with processing electronics arrive as one piece. Samsung has kindly applied an extremely sticky glue to this entire assembly which in turn keeps it tightly held to the inner body assembly and trim bezel.
The only problem with this is that the flex cable connecting the keyboard (they call it the 'navigator') is stuck IN THE GLUE between these two items (the rear housing and the display) and from what I can deduce is nearly always going to be torn when one tries to separate the display from the bezel and inner backing assembly.
If you order a replacement OLED display be sure and order this flex cable assembly if you're interested in fixing your phone.
Cheers!
Yep all went well except for that cable!
So if you still have the 2nd, let me know. Screen works, but the bottom keys do not. Extremely frustrating!
I am certain that I'm getting the post syntax incorrect, let me know and I'll adjust it.
Anywho, I found out too late that when removing the black goo from the LCD's flex cable, you need to:
1. Heat it gently
2. Pull the goo from the INSIDE EDGE to the OUTSIDE EDGE.
3. Not break that paper-thin, fragile, incredibly tiny sliver of plastic that is the difference between an LCD that will turn on and an LCD that will not!
So, I managed to do none of these things. I went ahead and replaced the digitizer and tried various (failed) methods of mitigating the damage I had wrought, finding no help on the internet, only commiseration.
Tonight I had a flash of inspiration, and what the heck, it worked. I carefully used a needle to separate the tiny wire tips protruding from the clamp (my poorly-considered sideways goo-removal bent a few until they touched each other) while wishing I had a microscope, then I prepared a short length of PLASTIC DRINKING STRAW, folded it in half lengthwise ("long-ways"), and gingerly placed it beneath the overlying digitizer cable so that it compressed the LCD cable against the contacts beneath. I put the phone back together, and here I am today.
Now, I probably should have laid a bit of tape over this so that it won't shake free. I'll wait until it shakes free to do that, then report back.
I fully expect this post to elicit discussion of the dozen ways in which to better achieve this repair, and why my method is the worst of the bunch.

Apparently, it's not such a bad idea after all! I'm just wondering how to adapt it to work on an EVO 4G. There's no ribbon to put it underneath, but I get the idea... one would think those incredibly thin/weak plastic clamps (which should be relatively simple to replace) could be purchases for 10 to 100 times what they are worth (say, $3USD?) and problem solved. I put an HD2 screen in an EVO 4G, worked fine, until I didn't glue it in properly, and it popped out. My g/f brought it back to me, saying that I needed to fix it right! I went back in, and that damned wide flex ribbon cable, just the angle I was at, along with my son jumping about the table I was working at, I inadvertently broke that clamp, in three pieces! Damned frustrating too! I gotta get me a dedicated desk for my PC/CELL/TV repairs... with lights, magnifying glass, and a locked door...
Well folks, I have outdone myself today. I was digging through my old tech to harvest the buzzer motor out of an old Boost Mobile Motorola i425 phone. After ripping it apart for the motor, I decided to pick through the rest of the parts to see if there was anything worth keeping (I bet you know where I'm going with this by now), and after harvesting the speakers, I noticed that the LCD cable looked suspiciously similar to the one on my poor Droid X.
3 hours later, I have fully repaired my Droid X. It was pretty tricky though, but I discovered that if you bend the metal bits at either end of the connector down, you can slide the clamp in and then bend them back upright.
Parts reuse FTW! Thanks Motorola! i425's are apparently $5 on eBay now, btw.
You saved my life (and the one from my Sensation). Such a simple and working idea! Thanks!
So, Im not a regular user, but I always read the forum and I thought it might be a good idea to share you this since almost nobody has reported that their back cover is lifting up, as it used to be a common failure on the original XZ (I own one) and not as common on en XZ3c.
Well, I bought the phone on January 11 and it was perfect, it passed the pressure test and had no problems, but on February 28 I realized that the phone didn't passed ir anymore, and then checked the watermark on de downside flap and it was red, and then WOW!! I Didn't even submerged my phone into water, I had just used a bit of water from a glass to clean it off, so it had no sense, well I said, nevermind is not waterproof anymore and is working great, it doesnt matter...
And Yesterday I was looking at the phone and realized the back cover is slightly lifted up on the camera corner, and if i press on that side and run the pressure test It works like a charm...
So thats it, Im raking it to Sony tomorrow, hope they tell me something legit and fix it or replace it.
P.S I dont use my phone as a game center, I dont have any game, heavy app, or record 4k video that might have heaten up the device and melt the glue on the back cover, I really think is a deffective unit.
PICS

You should be okay as in either getting a replacement or getting your device fixed without any costs, because there is no damage to the device and it's possible that the adhesive can let go.:good:
Yeah, bad luck unfortunately. Return it to Sony, hope you get it fixed/replaced quickly.
Good Luck!

Is... is that a cleaning cloth the phone is resting on?
Because there's still finger prints all over it, you could've used it to wipe the thing! Icky kicky all those smudges.
My money is on a faulty battery. It could puff up a bit and cause enough stress to lift the glass. If that's the case I would power the device off, leave it off, and don't attempt to charge it till it's been serviced/corrected or it could result in fire/explosion/injury/death...
At any point did you discharge the battery to the point where the phone turned itself off?

I Never discharged my phone below 20-30%, actually most of the days I arribad home on a 50% and charge it BEFORE I go to bed so it doesnt get overcharged during night charge... Im really careful with my phones I think is just defective, probably the heaviest app I had installed was Facebook... And Nerflix (which I never used).
Today I left the phone at Sony under warranty, I have to go in 10 days to get it back fixed or a new phone, depends what Sony says.
It happened to me to. They fixed it pretty fast, no questions asked

Glad to hear that! Did they replaced the back cover, glued the old one or replaced your phone?
Believe it or not, they replaced everything BUT the back cover!
So they changed digitizer, flaps and the frame (both the glossy part and frosted plastic part).
Also they unlocked my phone to all networks and made my bootloader unlockable.
So it was a winwin situation

Legit. Next time my wheel get removed from my car, I'll leave it on the ground and will put a new car right where my wheel is standing. It's safer.
Sony acts in strange ways
Well! Today I went to pick up my phone, and they replaced it with a brand new unit! Thanks Sony!
