hi, go on Ebay and buy this as I did once:
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=320037342618
Its exactly the same speaker that you find inside your s100... I did try on my phone but it didnt resolve the issue, so I guess it was a major soundboard failure and I didnt investigate anymore since I bought a new one ..but for 6 euros I suggest you to try...plus, the seller is in italy and he is really kind and serious.
Thaks for your reply, my problem is only the speaker because i've broken it, i hope to resolve the problem...
Which LCD display is it? Samsung or Topoly?
I have no idea, where can I check it out?
Look at the back of the LCD:
http://wiki.xda-developers.com/index.php?pagename=MagicianHardwareOverview
60H00032-00 is Samsung LTP280QV-E01
60H00037-00 is Toppoly TD028STEB1

my qtek screen have a crack line yesterday, but the display still remain perfect, but i can't touch screen anymore... i ithink will be the touch screen pad spoil, any 1 know where can get those hardware??
eBay is a good source for it!
You might wanna exchange the whole screen (LCD + Digitizer). It does not make sense to change the Digitizer only because of your LCD will not get better but worse!

Not sure, never tried to exchange it! But a look at the service manual tells me that it won't be easy!
I got one from ebay but it seemed to have some dead pixels. The seller is being cool (thus far) about exchanging it. We'll see how that goes
Its pretty easy to change out though. i can do it in like 5 mins now.

Hi. Ouch, it's not look bad :]
If lcd screen is not spilled(fuzzy,black dot's etc.) u need only front case
I see only broken window shield, digitizer work fine ?
btw. My HD droped from my bed(high frame) when i sleeping ;/ (Hah don't watching movies in bed maybe you save your HD )
I have only small stretch near 5mpix camera on the allu cam case.
I was walking on the stairs at the third floor when it dropped out of my pocket. It fellt all the way to the ground, at least 10 to 15 meters. My touch screen & lcd are both broken but I'm surprised it's not total loss.
Still .. sad.
hey friends , my hd2 was working very well untill touch screen stopped responding to any touch .. i haven't dropped nor damaged it anyway , it just happened suddenly ..
i found someone said it may be digitizer ribbon related proplem so i did what he advised :
[ Press the top of the red button (when pushing on the top your pushing the ribbon).
Press the bottom of the red button thus releasing the stress on the ribbon.
Press the green button. ]
i got it working for sometime then after i press on the red key it stop working again ..
please can anyone help me to fix this proplem .. ?
I got the same problem
Hi guys,
I have the same problem with my LEO 512, each time I try to reboot the device (Long pressing the power button) the touch screen hangs, but the buttons working properly, and whenever I activate the device by pressing the power button, or rejecting a call with it also the screen hangs.
I think there is a short circuit between the power button and the screen.
Anyone has any idea what to do to fix this issue???
Thanks
good day, unfortunately is a defect hd2 the only thing to do is send it in for service or replace the touch, have just made my warranty is also changing the screen and putting touch screen no longer equal to the original but different. the screen much more crisp and bright and the touch with a stunning response

I agree with you, I already sent it to HTC service yesterday, and first thing came to his mind that they would replace the "screen" or the touch or "both" , but he will check the power button problem first.
By the way, I got link (unfortunately I will not be able to submit it as I'm still new to the forum) this would help you. It is in the "Touch screen won't work" under the "General HTC HD2 discussion" in "HTCHD2forum(.com)"...

hey john , to which HTC branch you sent ?!
did he tell you that he can replace the digitizer only ?!!
& what about the cost ?!
also what is the important info. i can find in this forum ?
This is a common problem with the 512 HD2's. I have found that although some temporary fixes do help, such as using only the green button to wake the screen, and holding certain parts of the screen while pressing others do work in a pinch, but only a digitizer replacement will fix it permanently. The replacement digitizers are much better, and do not have the bug. Replacing the LCD with the newer one results in a much nicer picture.
Both of these parts can be found on eBay, and there are teardown videos on youtube to tell you how to replace them, saving you a fairly large amount of money if you are no longer under warranty.

Hi Needo,
I went to El Mohandeseen branch (Jovi Tronix), they have already replied me that they will have to replace the whole LCD screen with the digitizer, costing about 1,400 EGP (232$) which was a total loss for me .
Of course I refused, but thanks to "Cappii" who posted after you, I found the LCD screen with the digitzer in "ebay" which would cost about 475 EGP (78.5$) using "Edfa3ly.com service"!!!
A big thanks to you "Cappii"
I'm thinking of going to "Abd El Azeez street" first and check how much would it cost (if applicable), it would be faster than waiting for 2 to 4 weeks till I get the LCD screen from the US.
Wish you best of luck.

Anytime. If you do the repair yourself, make sure that you pay .attention to the connectors on the bottom of the main board. There are a few that are a little tricky. Overall, it's not an easy phone to repair, but it's a lot easier than iPhone 4's or HTC Arias.

Yes, I've watched how to disassemble and replace the touch screen videos on you tube before, I noticed that it is very complicated and tricky, but I like this kind of stuff, any way.

Thanks too much john , it's really great idea to use (edfa3ly.com) ..
also i've found someone can fix it for about 500 L.E (may be 400), they say he is expert with HTC & iPhone devices ..
if i repaired it myself , it will cost me about 300 L.E only , but with some risk as i heard that separating digitizer from touch screen can break it !
also i'll have to wait for about 2 or 3 weeks ..
i'm not sure about what i should do ..
what do you think ?!
& what will you do & why will you change LCD (i think the proplem is just related to digitizer ) & did you found it in " abd el aziz " ?!
& Thanks in advance sir

Hey Needo, What's up?
I didn't go yet to "Abdel Azeez street" but I'm willing to.
I prefer to have someone fix it for me; as it will be with less risk. But there is an advantage regarding getting the stuff from the US that you know they are brand new, not used.
I'm not expert in the hardware stuff, but this is the feedback I got from HTC that the whole LCD should be changed; this is why I need someone else to check it.
Could you please tell me more about this one you found, who can handle the HTC and I Phone???
Thanks my friend and wish you fix your phone soon (so do I )
Best regards,
John

sorry for being late in reply john ,
i sent it to this guy in " el srag mall " in shop called " Win Mac " he told me that he will change touch ( digitizer ) for 500 L.E in 2 days & he did it .. after i recieved it , it was working fairly good , but not like before .. then i tried to install WP7 , when it booted to welcome screen , found that i've no touch at all ..
returned back to WM 6.5 touch screen working , but not very properly .. tried to install NAND Android it gave me strange line of no.s & stuck at GO GO GO when i try to enter CWM ...
tried to boot into SD android Build , i got the same problem ..
so i decided to install WP7 again & sent it to him & told him about the problem , he told me to leave it & he'll fix it .. after 4 days i went to him & he told me that he tried to change digitizer for 2 times , but it's not working properly (in the best case , only the lower half of the screen got working) so he'll change LCD also ( the strange thing that he told me that i won't bey for that !!! & he will take my LCD instead ) ..
really i don't know if i should believe in what he say or not , but anyway i've nothing to do .. i'll wait to see what will he do !
what do you think ?!
Just wanted to chime in. I have heard various reports of having to change both the LCD and touch, although on my personal experience, the touch seems to fix it. Now, separating the LCD from the touch is a fairly simple process. Once the boards are removed, turn the unit over so that the touch and lcd are up. Heat the touch with a good hair dryer for about 3 minutes, and slowly lift with a plastic separator while its still very hot. Lift from the top, not the bottom.
There is a lot of tape on the bottomod the LCD. Heat LCD with the hair dryer, and slowly lift, keeping the frame flat on a table. If the frame warps, it will be next to impossible to reseat the touch and LCD. Make sure it stays flat.
Take your time and pay attention to all the wires. Take pics to reference where everything is. There is little to no tolerence for error on the rebuild.
I got it fixed

Hey Needo, I'm sorry for hearing that about your phone, I wish that it would be recovered soon, and this guy would be as honest as he said. I feel that he sensed that it's his fault to break the LCD. Anyways I wish that it would be fixed by now.
About me, I went to "Abdel Azeez street", hoping to find someone who might know something about this device, and you know what, I found that many people there already working with experience in Iphone and HD2. And I found that they fix it while you are with them to make sure that they don't cheat you, or fix it with used spare parts. For me, I found that guy who changed the touch in front of me with a new sealed one, it was a process of about 3 interesting hours, which cost me 550 EGP (91$). Of course it wasn't in the best quality as there are some dust between the LCD and the touch screen, and there is some light coming out from the bottom of the phone between the frame and the touch, but I consider them as minor losses . It's working perfectly now at last.
If you ever wanted his contact, I would be glad to forward it to you anytime.
cheers.
Dropped the phone, boohoo, glass shattered. lcd works fine and so do all touch areas. But the home button and back button do not work along the bottom. My overview/panels button still works.
So what do I need to replace? Will a simple glass replacement/Digitizer on eBay for about $10 restore function to the home and back button?
(as a side note - I think I can root the device + install permanent on screen action buttons right? The free stuff from Google play isn't cutting it)
happened to me a few months ago, I bought full lcd + digitizer from alliexpress. I believe it woul be very hard to separte the display from the screen/digitizer
Good to know they're available. I somehow got a tiny corner chip on mine (no idea how). Thankfully it's small and low enough that it doesn't affect buttons or screen.
Would this basically be it?:
Seems pretty simple as long as I can get my hand on a heating gun.

Yeah that is the one you need
That same seller sent me a message after I paid for the screen, he told me that there was low stock and it will take them about 6 days to restock, I decided to cancel the order and buy it from another seller but it was the same story, there was no stock and it took them around a week to send the screen.
I placed the order on Jan 03, the screen was shipped on Jan 09, and it was delivered on Jan 16.
My phone on stock rom has an issue where the left edge does not work. LeEco said it was a known issue. I literally cannot seek a YouTube video to time 0:00 because it stops responding at about 0:14.
Do you have any issue with YouTube seeking to the beginning with the new screen?

That has no effect for me.
If it is a hardware issue, I would ask LeEco to exchange it or I'll just replace the screen myself. LeEco tells me it is a known issue that I have. Now I am questioning if others have the same issue as me.
Can I assume nobody else has an issue with the screen/digitizer on the left edge, such as when seeking YouTube videos to the beginning?
replacement experience
Hi all,
For those who have change the display for the x720/x727, Have you found any significant difference from the original display? I need to change mine, and I have seen one on aliexpress. Sorry but I can't post the link because of the 10 post limitation.
It has many reviews, being almost all of them positive. But someone tells that there is no light on the capacitive buttons. I'd want to know if you have experienced this issue. Also, in your opinion, has the replacement the same brightness like the original one? Is as responsive as the original one?
Many thanks.

It has many reviews, being almost all of them positive. But someone tells that there is no light on the capacitive buttons. I'd want to know if you have experienced this issue. Also, in your opinion, has the replacement the same brightness like the original one? Is as responsive as the original one?
Many thanks.

For me the replacement one looks a bit better than the original. Everything works fine.
