[Q] HTC Desire HD Digitizer Replacement

Hi, I need help finding a digitizer for DHD.
Last week my phone fell down and the digitizer had broken. I know it didnt affected the screen because it still works fine, but its hard to touch the screen and to see in places with more light because the digitizer its all cracked.
If someone knows where to get a original digitizer for a fair price tell me please.
If possible I want to get it from somewhere in Europe because I live in Portugal and I dont want to pay all those taxes.
I have noticed now that I have another problems, maybe its just malfunction or the pieces are just out of place, but my Volume buttons and Wi-fi, GPS and Bluetooth only work when they want.
Im very upset because i had never left my phone falling on the ground and now I get all these problems for the first fall.
Its was not a big fall at all, it was less than 50 cm and it fell with the screen on the ground.
Thanks! :good:

[Q] A bit of help? Hardware problem

If I could kindly ask for some input...
I was helping a buddy sand his car down (old Midget ) for repainting with my phone directly next to my body. Got done and saw a bit of moisture in front of the front-facing camera lens. Touch screen unresponsive. Rebooted a few times, lots of ghost touches and hanging at the bootloader. Boots consistently now, but:
--Zero digitizer input but plenty of ghost touches
--No network access.
Can I maybe get some input on a plan, especially if anyone here has done hardware on these phones? I've replaced the screen on this one but that was months ago. Done a million different hardware issues but specifically wanting to know if there's any chance it's not worth replacing the screen. I feel bad asking for help on this but I really need to make the best decision.
Thanks Guys!

EDIT: The goddess of time has smiled upon my phone, and my phone smiled back. I waited 6 hours to post this and had the phone apart for at least that long, yet it looks like it hadn't dried out yet.
However....networking. Looks like the next step is flashing back to stock. Input?

been there, but weedeating

take it apart, see if there is any discoloration of anything(sweat...salt)
if you see any then be careful to remove it. i use lens cleaning clothes with a smudger
then. take a blow dryer to it
~*be careful*~ of course.(the phone can handle being soldered together so a blow dryer wont hurt it unless carelessly heating up one part.)
....i have never had rice work...
then let it sit for just a bit to air out. clean up contact, usb. gold contacts. headphone opening.
carefully...put it back together.
i suggest watching the youtube tear down of the phone

Cracked screen

Hello!
Today dropped my phone and screen got covered in spider web. The display itself looks fine, but its covered it spiderweb. The touchscreen doesnt respond at all.
What do i need to do now? I looked at local repair shops, they ask atleast 100 euros. But on ebay i can find lcd display+screen digitizer for 55 euros shipped, or screen digitizer starting from 10 dollars!
Can i buy only screen digitizer (as i understand that top layer of glass thats cracked is screen digitizer?) and replace it? Or changing LCD display along with screen digitizer is a must?

So this should fit..right? And are all 3 models LS970, E975 and e973 really same size? Cuz i`ve read people have got smaller screens than original from some sellers on amazon.

Replacing a digitizer is pretty hard and time consuming, that's why people usually replace the whole lcd+digitizer+glass assembly. You will also need adhesive and a heater/appropriate tools. It can be a great learning experience if you don't mind potentially busting your phone. There are no shortage of instructionnal videos on youtube on the subject.
Also, a new G2 is only 190$US .... Just saying ...

As i have two other phones. The g2 mini with Tegra and a razrHD. I'll give a try, thanks for the tip.

Well, i ended up ordering that LCD+Digitzer from ebay. Everything was fine for 2 months, now i have quite large spot that doesnt respond to touches. (See attachment) i already tried disconecting the lcd and digitizer..still same. Is it worth trying to flash another rom? I already flashed stock kdz (had stock before too..)
This happened just today, right after ghost touches went crazy and rondomly oppening everything.
EDIT: That spot is changing sizes..form remains, but it got a bit smaller now. Its truly weird. I put the phone outside for few minutes (its +9C outside) and touchscreen works fine now! What is going on?
EDIT 2: After few minutes of usage, the spot is coming back

I had dropped my LG (more than a couple of times) on its face and it seemed to suffer stroke-like symptoms: one side of the screen was completely dead to touch, and the rest of the screen would occasionally act as though I was touching everywhere which opened programs and messed with the keyboard. I was stubborn and just lived with it and over time, it stopped trying open programs and whatnot. Recently, dropped it again, this time it was a bit more serious. Still no visible damage to the screen, but the "dead spot" moved to the centre of the screen, and again, occasionally tries to open programs and add words to my messages.
At first I thought it all could be related to a software issue. Unfortunately, after installing new ROMS, it never fixed the problem. I bought a digitaliser screen from Ebay as well. I'm waiting on the adhesive tape still so I can't say if this will fix anything. I kind of have a suspicion that its a loose connector (the top middle part of the screen gets super hot only after a couple of minutes of being left on).
I'm just wondering if you have tried taking it apart again to recheck the wiring? I think we may have similar problems (your situation is the first I've come by on the internet that is anywhere close to what's happening to my screen). Thanks so much!

Some questions regarding Note 2(Cracked screen)

Hello there, I've done some tinkering me and my dad and decided to change the display of my note 2 by ourselves, we where trying to change only the glass(the one that you touch, is white or grey, etc) and we couldn't separate the glass from the first layer of glass the one that has a ribbon cable hooked up to it, well we tried again and we cracked the second layer of glass and then we got two scratches on the third layer of glass (I'm not a professional guy that's why i'm describing it like this). Well either way the screen won't turn on now, the led is turning on, it vibrates it just won't turn on, talking about the screen. Now here come the questions, Will I be able to fix the screen to turn on? and I saw a demo unit of the phone for sell on the internet would it be worth it to buy it and switch the internals(motherboard, usb module, antennas) to that phone just for the screen?
I'd rather go the demo unit way - if it's possible - because that would cost me 100 euros instead of 170 euros.
Thank you very much for looking at this.

I think you cracked the display ...sorry. Why you coouldn't separate the digitizer from display? You just need a few pieces of plastic, playing cards or similar things and a heat gun. Probably you did not had enough patience to heat it.

To move the entire screen to another phone, it takes a bit of skill, search YouTube and decide if you can do it.

I think you will find answers here:

Good Luck

I was saying that I'm going to take that thing on which you screw the motherboard and antennas. From my understandingnthe whole LCD assembly. Would that work? At this current stage I'm trying to power on my phone to save data which is possible and the next step i don't really know what to do.....

touch screen not working. replacement screens same issue

i've got a sob story and i need a little technical ..and emotional advice.
I love my Mi5s. I lent it to a volunteer helping me in a charity project and they broke the screen. can't really ask them to fix it as it was my project and they were helping me out. The new screen arrived and as i was having a seriously busy week i decided to take it to a local shop rather than fix it myself, un-gluing looked like it could get tricky.
Well, the guy gave it back and everything worked fine, but he hadn't glued it down properly and wrapped an elastic band around it tightly to 'let the glue stick'. i opened the box the next morning and the band has cracked the screen.
Ordered a new screen and took it back to the guy. he broke it so he should fix it for free. he says the screen is wrong one as touch screen isn't working. i'm sceptical so i come to pick it up.. and that screen is cracked too.
Ordered another screen and fit it myself, but touch screen still not working. I suspect the guy has broken the touch screen, but he insists its because i've bought the wrong screen.. although the 1st one worked fine.
Tldr: tried to save 2 hours, lost 5 months, 3 screens and my touchscreen still isn't working .
Here's photos of what i have now. Can anyone see anything obvious or suggest what he's done/what i could do to fix it?

Check pins where display/digitizer connects to motherboard, see if there is any 'blacked' pin, like burnt or something like that.
