Hey, guys sorry for my English first.
I have a problem with the camera device and I see her a lot of people also, I sent for repair and came back, worked, after a week \ month again with the same problem stopped working.
I thought I might try to order from EBAY new camera and go to shop them to put it, what say?
Thank you.
Someone? Help
Ive not opened up a htc hd7 yet but usually the physical camera circuits are hardwired to the main phones board so swapping it out isn't an option. replacing the buttons or even the lens might be possible.
this place has an picture of a part they claim is the camera module for an hd7
I'm assuming the phone wont take any photos or initialize the camera from neither the hardware buttons or from any software app on your handset.
and also HTC will give warranty repair for 1 year from the Manufactured date or point of purchase you do not need to necessarily be the original owner. Id give them a call and confirm that it isnt covered before going the open it myself route.
Thanks for your response, about responsibility, I can say he fought with this device and responsibility for six months, just send it for repair, return, working a month, sometimes less, and destroyed again.
Dee gave up messing with it, that's why I ask.
By the way his responsibility was over.
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

i am sorry, but ppl in here(p970) isnt as good as ppl on s2 or s3 thread.......
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
Hello
I have a problem with my Htc One. Someone had this problem? (when i zoom in camera)
1/ http://hpics.li/d46ad94
2/ http://hpics.li/8ff1391
3/ http://hpics.li/0b9d54b
when I print the picture, it appears too.
My htc is in after-sales service. I'm wait answer.
Thanks in advance (and sorry for my bad English).
no need to think too much. send it back to store, it's faulty. I had a faulty one with a ghost spot and switched to a new one.
Yes, agreed. That's not software.
Yes I think is not software but hardware.
You think HTC will change just the camera or I'll have a new device ?

take it back to the store you bought it from and they should swap it. If you bought it recently.
otherwise you'd have to send it to HTC for warranty repairs, and they'd probably take it apart and just swap the camera out.
Recently I've reopened my HTC HD2 to glue the glass+digitizer better to the case since the replacement BUT I accidentally damaged the flex cable by cutting the UP/DOWN volume buttons flex....
...I've already ordered 3 from eBay and from different sellers and the symptons were:
1. Bad Sound through loudspeaker (static), Camera was flickering with pinkish tone
2. Bad Sound through loudspeaker (static), No Vibration
3. Bad Sound through loudspeaker (static), Vibration worked but no Proximity sensor (literally)
Suffice to say I've waited nearly 1 month for each arrival...spend time to install and make a video to show the seller I was not lying...and now I'm using the HD2 without the volume buttons but with everything ok....I'm nearly Ok wasn't the fact that the Vol keys have a number of functions I use: Camera button, Silence a call and most important flash new rom's.....
Can anyone help me find one that REALLY works?
I would say your best bet is getting a used device being sold with dead or broken original digitizer.
Prices are very reasonable these days & even if twice the price you will reclaim the cost by selling other genuine parts via eBay.
Quality of chinese manufacture on mainboard flex is going be a problem as they love minimal manufacture cost (even leaving components out:-O )

Maybe you're right...and that's what 'll try to do next time. What I don't understand is the large number of happy costumers buying those flex's and reporting no problems...
I think a lot of people write feedback before fitting or testing well.
I do suspect some work well but indeed they will not be near quality of original.
The digitizers & button boards are good but flex is one of those things where genuine if possible works out best.
Should be easy pick up a salvageable HD2 besides bad mainboard or digitizer & with your gained experience strip for parts.
maybe you can try on www.aliexpress.com
I recently bought this one - http://www.aliexpress.com/snapshot/6129733847.html , but i've given my HD2 for assemblage, as I am not able to flawlessly do it personally . i can post the results in a weeks time and tell you how it works.

Did it work ok? Camera, Sound, VIbration, Proximity sensor?

Same as ones on eBay - amazon, you'll find that seller on eBay too.
Main flex is always best salvaged from a cheap broken HD2 rather than copy part as just too complex & important for cheap china copy part.
I got the phone new monday
I've done testing and I have no sound on the main microphone
It just replays recorded noise
Is it hardware or is there a known fix to this issue ?
thanks
If it's a new phone, you should probably just return it and ask for another... Someone on a finnish forum was complaining about the same issue of microphone not working and said that he got a new phone from the store and the problem was gone.
Maybe Sony has had a bad batch?
Hello! I have the same problem...
Does anybody know if is a software of hardware issue?
If you bought a new phone from a store, why not just return it and ask for a new one? If it's defected from start, I wouldn't try to fix it myself but demand a working one.
Can't do it. bought it new from someone
Is somebody that solved this issue? VHollund?

That someone should have a warranty
In my case I bought it from internet store in france and we have 14 day retraction right + 2 years warranty, so I send it back
It was not a software problem
You can test the microphone by going into the systems settings on the phone
If you have no warranty, you can use a head set which is what I do most of the time anyway not to get my brain fryed
It will stil work on speaker sphone where the 2nd microphone is on
Some developers might be able to help you hack it to use only the 2nd mic
I've seen inconclusive threads about it

ok, thank you! I will try to send it in a service to replace the microphone
I have discovered that Sony put some rubber over the microphone and that's why it wouldn't work The microphone is fine

How did you remove the rubber ?

I recommend you go in a service to get it dissasembled. Thatrubber you just get it off and put in with the hole over the mic hole, not covering it. But if you have warranty i reccomend you get one new
If you do this you will void your warranty and it will not be water ressistant anymore
It took more than a month from the order but i received a new one yesterday and it has passed the tests
It seems to be a great little phone, I just wish the camera was better
It's very grainy and my 2016 samsung A3 took better pictures with only 13M rear camera
Decided to stay on Oreo for now since Pie does'nt seem to fix the grainyness
