Hi,
The XDA Diamond of my little brother has some cracks between the display and the touch-surface. (see attachement)
I sent the device O2, but they (their service-partner) said "no warranty" and want ~ 300€ for the repair.
I just looked into the service-manual, because I thought about repairing it by myself.
But I think it's to difficult for me.
Now I wonder if anybody know a cheap mobile-shop, who can repair my Diamond.
I live in Cologne. My Brother (and my family) near Hannover. (both in Germany)
But Online-Shops are also good.
Thank you!
the screen is on ebay - item 230285205211. They also offer repairs
search for the dismantle guide (sorry don't have it to hand)
i also got cracks on my screen just like your brother....
I decided to order one of the replacement screen from ebay that comes with the needed tools to do it myself. i payed about 25 dollars including shipping and should receive it anytime from now.... If you r willing to wait , i ll post feedback on how hard it is to do it yourself.
About dismantling the diamond u ll find easily links from google.
Good luck!
how do the cracks actually appear in the first place?
was it the result of something the manufacturer might classify as "abuse" or "accidental damage"?
Often I pick up my phone (HTC Victor) and think that it feels quite fragile compared to something like the N95... so i treat it accordingly - ie, with a little more care..
I already looked throu the disamble guide.
@Sebienbon
It would be great, if you would post feedback and maybe photos of the repair process (step-by-step) wich are not in the disamble guide.
Meanwhile I will do one more try with the service partner.
@bobbified
It just happened. I think my brother carried the device in his trouser pocket (jeans) when he was riding by bike. But imo such a expensive phone should be strong enough.
Also theere is no damage on the outside.
@hays
Thanks. But I am not sure if this is the right part.
My LCD still works. All pixels are fine.
But the "whatever" between the LCD and touch-surface is cracked.
Thanks everybody so far
i just got the kit this morning but the screw driver is wrong( probably because of a different country , i live in denmark and the screen comes from asia... so i ll go buy a tiny screw driver that i miss and then give it a go
Hey,
I´ve got the same problem. But my Screen is more broken
Although it works.
I read the Service Manual too but im not sure if it works with this part:
http://cnn.cn/shop/touch-diamond-digitizer-p-2128.html
Because on the last Picture in the Manuel you see only the front part of the phone and nothing about the part linked above.
So I w`ont open it before I`m not sure whats exactly to do.
Also I asked some firms do make me an offer for repairing the mobile phone.
The best offer is 129,00 € or 169,00 € if the dismantling create scratches on the Display under the touch screen because they are glued.
Very expensive!
Now I´m waiting for your experiences too.

Any update?
no updates
Man i wish i know of the manual to take this apart. You can fix it yourself if you take your time man, and dont be like me man. I took it apart thinking that the black tape under the battery is just tape!!!! And rip the mini-usb power ribbon. Man my heart sank.. So on that note if any of you guys know of a site or store to order parts from. please let me know also....
@lphar56
Is the diamond display made of glass and not the plastic stuff some other screens are made of???
The display is LCD so im guessing glas.. but it has a Touch Digitizer over the top.. that can scratch very easy and is only £15 off ebay
GET INSURANCE........
IF IT BREAKS, MAKE IT DISAPPEAR CLAIM FOR A STOLEN FONE
HTC diamond screen replacement
Hey guys!
AFAIK the cracks that appear are in the glass of the touch-screen-unit.
so i try to figure out how to replace this part only.
Is it glued to the LCD?
Which glue sould be used to fix it again?
Or does it even come with the screen?
I'd like to post a guide here if it works, so please help me answering this last question!
Also, replacing only the touchscreen would lower the repair cost to a third...
Thanks!
Still no update?? on the steps to remove digitizer?

Has anybody a guide or experience on changing the screen? I have the same questions as above!
Hi Folks!
I have a tiny injury on the Display like a stone-chipping, now the touch doesn´t work anymore. He think that I pushing on this point. :-(
I found the LC-Display (89€) and the touch-unit (59€) to buy. On "hot-wire-telekom. de"
Is there any guide how to change the Touchdisplay?

**I also have searched this problem before creating a new thread
I recently dropped my phone(thats in a hard plastic protective case) approx 2 feet onto the ground. I picked my phone up pissed at my clumsiness and i noticed the phone was still working perfectly fine but everything that is supposed to appear dark is now light and vice versa. Im kinda low on funds right now but i was wondering are there any alternatives other then a screen replacement
Just checking in I have tried a few things any input would be appreciated...I think im going to go to cingular
I will post up pics to show what the phone looks like to help others who may experience this problem
It could be false economy attempting a repair yourself

I wouldn't go buying a replacement screen off the bat, it may simply be something like the flex cable has come slightly ajar. A good repair centre that know their stuff will correctly diagnose it, only replacing whats required (possibly saving you money from buying parts that aren't needed).
Thanks now my next issue...lol is finding a reputable repair shop
I have been to two places thus far and one person looked at my phone and simply said thats going to be $140 to repair before taking it apart or any diagnostics and another place wasnt even familiar with my phone so the search continues
And thanks for the help
Hi i'm currently looking online where to by the two (i think) GPS and WIFI clip on cables, dont know what their called?
would love to see hem on ebay but i cannot find them
anybody help? where can i buy them or what they are called?
thanks in advance.
FYI: the two small cables inside the diamond wich clip onto the PCB's, not external cables.
EDIT: am i on the right track as this connector seems the same? is the connectors calles "U.FL Mini" connector? would this connector be correct and fit?
thanks
Does nobody know then? lol... i'm at my wits end trying to find these cables never thought it would be this hard, they both snapped on me and now i dont have good GPS/WIFI reception. please help somebody...
bump, sorry... does anone have any to sell me then, why is it hard to find these, not even ebay has them google results in 0, really bugging me now, what other phones has these? somebody must know something... xda dev is the source of this stuff man, i even went as far as ringing HTC bu they cant tell me where to find them or what they are called, i apparently need to send it in, pfft for the cost of what lol.
I cracked my screen so I decided to order a new one and fix it myself, while in the process I accidentally tore the top flex circuit board and now I can't find spare parts other than screens anywhere. Does anyone know where I can get some or have one that is broken I am willing to pay ...
Hate when **** like that happens. . . try to fix something and something doesn't go right.
Not sure where you can get the parts you're looking for, but wanted to give props to you for taking the initiative to try and fix it yourself. Alot of people will be like "that's what you get for not just sending it back to HTC and having them fix it." How're you going to appreciate the intricacies of something if you don't take the occasional risk like this?
Hope you find what you're looking for.
Ps. Have you looked at http://www.monoprice.com/home/index.asp to see if there's anything you could repurpose to work?
Ha yea, I am definitely a DIY-er. Unfortunately this is a risk I knew I was taking heading into it, wasn't too worried though because I have fixed a lot of cell phones in the past, just got a little too careless with prying open with a flat head screw driver, it slipped and cut right into the flex circuit board. Should have been a little more careful haha. New screen looks great though! Now only if I could get it to power on! Of course HTC tells me it will cost up to $300 to send it to them to fix it.

Not sure exactly, but is this what you are looking for? http://cnn.cn/shop/google-nexus-digitizer-p-8252.html
Yea I tried that number and also that lunacommerce site is located in China, no prices on their website, no way to purchase anything other than contacting them first (which I have tried to no avail...). You would think some online store somewhere would have started selling spare refurbished parts. Whatever, guess I will have to pay HTC to fix it, kinda sucky.
If you find somewhere that can help you, please post back. I just had a similar experience, replaced the digitizer and the display wouldn't work afterwards. Figured I had damaged the AMOLED, so purchased another. Problem still persisted.
I've decided that I must have damaged the AMOLED connector on the logic board.
The upside is I can still use the phone when connected to a PC and using Android Screen Monitor.
So now I've ordered another Nexus One, I find it hard to get by without my daily Android.... it became an expensive drop of the phone.

No that is what I replaced in the first place. I am looking for the Logic Board. I will keep searching and update this thread if I ever figure it out. Going on 3 days without a phone and only being able to use Google Voice via my computer is starting to drive me insane!
Hello,
so today I bought a second-hand LG optimus black that was soft-bricked and had a cracked touchscreen. Since I'm not new to android and know how to fix these things, I thought this was just another way for me to get a good phone cheap.
The problem is:
- after unbricking the phone, and installing official v10a software, there are issues with the phone - camera force closes, any of sd cards wont be recognized ("removed sd card, insert a new one" notification, never changes), the screen rotation doesn't work, there is no lockscreen, phone dialer has lags, and the screen turns on after 5-10 seconds. Otherwise it's ok.
With software v20b it also likes to hang up. Theeen you have to remove the battery
So I dissasembled it, and it seems to have short circuited somewhere on the motherboard (there is a brown spot on the metal motherboard cover plate).
I marked the area in a picture below (notice that it's right next to the SanDisk chip - i guess that organizes the memory, so it should take care of the sd card as well). Keep notice this isn't the picture of my motherboard, I will post my own photos a bit later..
Maybe it was waterdamaged, but the sticker on the battery is white :/
Please don't tell me to factory reset, or try other software or memory cards, already did that.
CWM won't detect memory cards as well.
I need any possible ideas to fix it.. do you think a reflow would have any chances to do the job? any ideas, please, will try anything..
PLEASE, help.
Some update. So I flashed software V30B, and it seems to get better - finally I get a lockscreen, and not in 10 seconds also, the accelerometer sensor is working, phone is smoother. FRONT camera is working as well, while in video call mode, yay! when turning on the camera, it has a black screen with all the buttons and camera settings, and a message that there's no sd card (although it's inserted :| ) and hangs up if I switch to front camera. Memory card still not detected..
Thinking of capturing a video to show you whats the situation.. Till then here are some photos to show you my beauty
P.S. don't be shy, guys, any ideas for fixing?..
the photos
Anyone?
I thought I would get some replies, at least maybe I was wrong

maybe on s2 there is chainfire, that undrrstand phone by hardware and software....but here....even development is on "almost dead" stage.....no stable cm, even cm7.....so sad.....
so....dont expect professional answer soon.......
and btw..try your luck on android hardware hacing thread....maybe there is some answer for you there

Thanks for the reply!
Well I thought I would find more hardware technicians here, but whatever..
I downloaded the service guide for optimus black, and after looking at the schematic sheets, I'm 90% sure it's "SUB PMIC CAM POWER (LP8720)" controler that's failing. It controls the 5mp camera, microSD card and motor driver (vibration) power supplying. Neither of these functions are working on my OB. So no need for hardware hackers, nothing new they can tell me. So I'm thinking of ordering this pmu, but could you tell me guys where I could get it from with normal priced shipping? Shipping time wont matter at all.. Digi-key and mouser want to charge me with 40$ shipping, while all I need is a 2$ part

well mate, i have no idea..... i am just normal customer, if something wrong with my phone, and i cant fix it, i always go to official service center......
but, i hope you got some luck out there, happy shopping
Makes sense. Most people don't believe that ICs are a very sensitive component.
Obviously, I can't make a theory of what's wrong on that device, as I don't have it here.
Do you have a multimeter? On the service manual you might have somewhere what to do (e.g. where to measure voltages) if some functions are not working, or did you already try that? I know the service manual always ends with "replace pcb", as usually the technical support don't actually do the repairs, they just follow what's on the manual and send the old parts to the manufacter for repairing and reassembling, but it might help you understand if you really need to replace this IC. Is there any fuse nearby, for example? Remember, a short circuit would break fuses. You can check with a multimeter whether they're damaged or not (continuity test).
There's not much I can say, really...these are just some suppositions...
Good luck with that, man

I do have a multimeter, I'm kinda into electronics so..
Yeah, so I had a little break and checked the phone out only a few minutes ago.
The LP8720 is the problem, but its much more f..ked up than I thought..
I marked three spots on the circuit that are quite odd:
1. The place where IC U601 - LP8720 should be.
2. 2.2uH wire wound resistor L601 (MIPSZ2012D2R2 MIPSZ2012D2R2, 2.2 uH, N,2.0X1.2X1.0), not sure if it works, maybe it burnt out, my multimeter shows 0ohm on this one.
3. The place where capacitor C604 (10uF) should be.
I attached the pic of my motherboard, you'll see whats up..
The only place I can get LP8720 is alibaba.com, and the minimum quantity is 10.. that makes about 16 bucks for these. Would be worth buying and trying to fix? And another thing, it's named LP8720TLX-B, not LP8720TLX. Do you think it'll do?
I'm now thinking of taking it to a service center, ask if they could do such a job and how much would it cost..
Thanks for the replies, by the way!
Peace

Hey man,
keep an open mind
What makes you so sure that this IC is damaged?
Think: if the nearby components are damaged, then this IC may behave differently (or may not work at all). We don't need math to think this.
But yes, it can be damaged, but since this is the most expensive component, I think it is really worth checking the others first.
Anyway, answering your topics:
1. Everything looks fine. Good ^^
2. Yes, it's probably damaged. An inductor is supposed to have resistance, but not much. For this one, 0.23 ± 30% Ohm.
Source (datasheet): http://www.fdk.co.jp/cyber-e/pdf/CD-TCE070.pdf
3. Fortunately, this is an easy one. If in doubt, just replace it.
Now, for the headache...LP8720TLX-B and LP8720TLX might be the same IC, but the only way to know this is by comparing their datasheets.
16 bucks is a lot to pay for a component (yeah, it's 10 of them, but it's still a lot). But this is actually your call...are you willing to pay 16 usd for an IC? If it was me, and I was entirely sure it would fix everything, I would probably buy them, but then...like I said, your call.
I think it's worth taking it to a service center, but if they truly follow the service manual, they will tell you they need to replace the entire pcb. But I really think it's worth to try, you never know.
Good luck
