So one of my friends at work had an att tilt. However his son dropped it out of his pants pocket and the screen popped off. Screen is still in one piece however completly seperated from the tilt mechanism and the ribbon cable is missing. So I told him instead of throwing it away (cause att does not offer insurance) to give it to me and I'd see what I can do (Gonna unlock it and use it as an upgrade for my wing ).
I've read some of the hardware manuals and can already see I'll need parts to fix it. But I have no ideas what ones. Or if it's even worth it to fix. I mean its basically a free tilt minus any repair costs. Any help?

Thank you, however thats actually the repair manual I looked at. However while looking for parts I have yet to find the ribbon cable that connects to the display.
This is basically what I have except the ribbon cable is missing. And alot of steps missing to get it this way.

OMG, that had to hurt.
Yeah, kid was playing basketball and fell out of his pocket. I guess the kid has broke 4 phones this month... curve, tilt, 2 pantec duos. Told my friend to get him a $20 go-phone now lol. And use the savings to get me a tilt
I dont know what kind of damage besides the physical the drop may have caused. Phone was not on at the time so that may have helped it (I hope)

I hope u repair it. Wish u luck.
Without actually looking at it, its hard to say what exactly you need. But you for sure need a new flex cable. Unfortunately that is the hardest part to find. At least here in the US. I usually buy broken phones from people who don't want to pay for a repair. Then I use the parts from them. You can get a new housing easily enough if you need it but the flex cable will be your biggest hurdle.
I suggest trying to find one broken on ebay and using the 2 you have to make one working phone. Even a broken Tilt can run for $200 on ebay though.
Anyone notice that case has already been replaced at some stage as it has a camera hole (not standard for Tilts) a keyboard without the white part and no logo. Perhaps the replacement was weaker than the original one. If the O/P searches the forum here for LCD Screen replacements there's loads of links to different companies supplying parts for Kaiser variants. I have no experience using any of them though so cant suggest which ones are best.
@Planet Neo
Yeah I was thinking that but was hoping it wouldn't come to that. Would suck to spend $200 for parts just to find the motherboard is broke or something to that effect. Was hoping someone knew of a place to buy a new cable or had one to sell. Also was hoping someone with some experience could let me know if they think I'd need a new tilt assembly.
@Flying Kiwi
Lol, I used a picture from kaiser disassembly guide to show what i was referring to. It has the standard tilt case. I'll be taking pictures of what I have as soon as I have the phone in my possession.
Okay I assume that its going to be very hard to get the ribbon and you're going to need housing. I believe that it will be the same as making a new tilt, because the screen is as good as dead without the ribbon so all you could do is get new housing and a new screen and it should rack up about $150-200. Which in my opinion is much easier and faster and better than frustrating on getting a ribbon.
Just my 2 cents.

I'm sure you'll think I'm busting your balls / stalking you but hard to find? Hell no! Expensive, maybe ( $100) but hard to find? I think not. Good job you're not charging people for you expert advice else they'd be wanting refunds....how long did you say you'd been doing this for?
http://search.ebay.com/search/search.dll?from=R40&_trksid=m37&satitle=tytn+flex&category0=
You need a TYTN II flex. There are many other suppliers and if you go direct they may be a bit cheaper. google is your friend....
To check the board - connect to a windoze computer with a mini USB cable and power up or press the soft reset button to boot it - it should ident and install then try to sync. It should boot fine even with no LCD if it's OK assuming the battery still holds some charge.
A full housing will run you about $60. Some sellers have just front panels for about $40 though I'm unsure if these have the pivot.

Man, MS you really need to get off my nuts. It's getting creepy. I said in my post hard to find at least in the US. And the link you gave was for a seller in China. One more word of advice for the OP, Make sure this part actually works for the AT&T Tilt variant. I had a customer buy a Flex cable for the HTC Herald thinking it would work for the T-Mobile Wing but due to the modified button layout of the Wing it did not fit correctly. Much like this person HERE experienced.

These things are made in Shenzhen so where you think the parts come from?
Stop talking &*%(* and I'll stop correcting your posts Instead of saying something is a fact say it's your opinion. It's not a 'rare' part - and they ship WORLDWIDE. It's not as if he'll get one from a local mom and pop store - it's gonna be mail order wherever you get it from and looking at the seller's feedback is a good judge - all my parts come from China - so why pay a middleman such as yourself extra $ just so it has a US stamp on the package?
Someone needs to act as quality control on your posts and it looks like it's gonna have to be me if you keep posting [email protected]

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!
Currently, i have a $600 pile of garbage because I can't get a $20 part. I am hoping that someone one here might be able to help me out.
The piece I am looking for, i believe is referred to as the "Vibrator with Frame". The link below, is the only place I can find the piece, but after numerous emails, I get no response, not sure it's because I only speak english, or they only advertise it, but don't actually have the part
http://www.lunacommerce.com/269-google-nexus-one-vibrator-with-frame.html
There is a piece of electrical tape attached to this part, but underneath it lies the antena for GSM reception (wish I knew this beforehand), an orange colour.
So, does anyone on here have any idea how I could get this piece? Does anyone have a bricked nexus one wanting to sell any parts? PLEASE, ANYONE????????
I have contacted HTC, (unbelievably), they claim there is no parts department, so I can't get this part from them, unless I send in the phone (which I am not willing to do). I was thinking there must be some third party repair centers that might be able to get this as well, but they couldn't tell me of any.
Also, I don't need this thread to be full of comments suggesting I shouldn't had taken this apart to begin with, I realize my mistake. I am an electronics technologist by trade, I have taken apart many devices in my time, just had some unfortunate luck this time around.
Any help/suggestions would be appreciated.
Not to be unhelpful here, but when I read the title of this thread I thought you were looking for something toooooootally different.

Well, first off I just realized I should have posted this thread in Q&A section, sorry Moderators.
Trust me, I realize that (in reply to quoted comment), if you think about it though, my subject is the literal part I am looking for, what I need (the antenna), is attached to this part.
I never thought originally that this was the part I was looking for either, but this is the only way to explain it.
ive seen 3 sites for nexus one parts somewhere either in the Q and A or the accessories forums.
Found the part, problem solved!
Well, thanks to a pm I received, I was able to order this part through ebay. Had to spend a little more than I wanted, but at least now I can put this back together and have a working phone to sell.
To respond to the post above, yes there are many sites with "parts for Nexus One" phones, I have been to many, many sites. I wouldn't have posted such a detailed question to begin with if it was that easy. All of these "parts" sites, offer aftermarket accessories, not internal components, well besides the touchscreen and digitizer.
Anyways, problem solved (hopefully, not sure until it is installed I guess!)
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?

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......

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
I have a samsung galaxy note 9 on sprint currently, the phone was dropped and smashed but not too a unrepairable extent. I currently put a new battery, charger port, and wireless coil. The phone won't charge still unless I use my s20 ultra as a wireless charger which says its charging but I cannot get a light, vibration, or any screen activity so I'm guessing the motherboard is most likely toast. There is no water damage and I will be replacing the screen glass I was hoping I could get a image before I ordered one lol but the real question is the phone is on sprint I was wondering if I can purchase a N960F international model motherboard and use it in the N960u shell. I want exynos for the simplicity of rooting. Also The charger port I installed was off ifixit and labeled for the n960u, n960f, n960fd but read somewhere there's a difference in charging ports? Any information is greatly appreciated. This phone will most likely be used on AT&T
Does anybody have any insight on this issue?
I you dropped and made damage anything, i guess you might have the same issues, but otherwise if motherboard fits in place correctly it should work, the F variant is exynos ad should work with all networks, and sure you can root it.
No guarentee it will be a pin for pin swamp or that the subassembly components/firmware will be compatable.
I think it's unlikely to work.
You need someone that did it to know for sure otherwise it could be a big lick on you. Even if it's possible no guarantee the replacement mobo is good or won't be damaged during installation (think ESD). If you had all the major components you have little to lose otherwise you might be kicking a dead horse.
With that much damage buying a working one with the right configuration be a better bet...

I'm sure to be careful with my electronics, but you are right. Looking at tons of pictures the motherboards seem identical in size, all the parts I bought said they were compatible with both models ill be using all n960u parts other than the motherboard. I read somewhere the charger flex is different but I can't see or find any ones that are different, also same for the cameras. This will be a pretty sweet experiment I guess. If they screen works the cracks in the display aren't too bad that it wouldn't be usable. I'd save about 80$ (if I don't buy a bdot replacement) all in all spending about 200$ in replacement parts. Not too bad if you ask me. Considering it's my gfs old phone that she didn't end up paying off since it broke I don't think it'll be a bad deal
I'll be sure to update any progress I have the motherboard will be in around the 15th of march
I changed my mind, perhaps rubber conectors are different?

Screen, camera or USB connection cable might be different size or location.
Boards may look same but their functionality may differ as both boards have different CPUs. snapdragon variat have FM radio enabled so 3.5mm jack may have different port configuration same goes with cameras and so on..... Best is to buy a exynos variant F model.
