Ok guys, need some help here....
Got a HTC TyTN II.... Worked great for like 8-10 months, then started having issues with the screen.
Sometimes when brining it out of sleep, the colors are all jagged, and the screen is out of sync and staticky (kind of when you have a VGA monitor and you half pull the cable out of the connector)...
So I'm assuming its a problem with the ribbon cable coming loose (if thats how its connected).
Another thing too, the memory card slot doesn't work anymore. This just re-inserts the fact the ribbon cable or whatever for the front of the device is loose.
Does ANYONE know how to fix this? Unfortunately I tried to rip the phone appart myself and voided the warranty...
Anyone else have these problems?
Sometimes the screen works, sometimes I have to put it back to sleep, wait 5 minutes, and wiggle the front. hit the power button and it works. This has happened across 3 firmware updates so it's hardware for sure....
It does sound like a piece of hardware is loose. The fact that your mem card is not working further suggests this. I took apart my Tilt yesterday to replace the screen which no longer responded to touch, although it still worked with hardkeys. As part of the process I noticed the mem card slot was integral to the screen components. In other words, the screen and attached component, including the mem card slot is loose. For video as to how to pull apart your phone, go here. I have never done this before and this video worked beautifully. Also, search the forums for the HTC Service Manual and go through this page by page, step by step matching it against this video (if yo have dual screens even better) and you will come out fine. I did!

You can buy replacement screens and the tools from the same website. Otherwise try eBay, which is what I did. Definitely get yourself a strong pry tool. The one I bought from eBay disintegrated in the first couple of minutes. Luckily there was just enough of tip of the pry tool for me to use brute force to pry open the case without damaging the phone.
thnx bud, ill be posting my results.
I have been trying to repair this phone, but the usual faults have not turned out to be the problem. This is the background on the repair efforts:
In my research I found 3 main causes for a dead touch screen.
1) Corruption of system software.
2) Failure of digitizer cable (hinge FPC)
3) Failure of digitizer screen (touch panel)
To check for #1, I flashed the firmware again (after a wipe). I downgraded to Android 1.5 because I wanted to root the phone and install CyanogenMod Android 2.2 Froyo.
This was a big mistake because I learned that when you don't have a working touch screen, you cannot get past the "Touch the Android to Start" screen.
So on to step 2 - replace cable (hinge FPC). I have a G1 parts phone that was lightly used in good condition before it was damaged. There was no damage to the sliding section, so I expected the hinge FPC to be in good condition.
So I installed the hinge assembly with its hinge FPC from the parts phone, but this did not work either.
So next I installed a new touch panel (digitizer screen), but that did not fix the problem either.
I had a chance to borrow a working G1 motherboard, and I was surprised to see that the phone was working with the borrowed motherboard.
So my question is whether my problem motherboard can be recovered with a software solution, or if these symptoms indicate a hardware failure.
I thought that a wipe followed by firmware flash would eliminate all soft system errors, but I am not sure if the wipe and flash really erase absolutely everything, or if there is something else I need to do to get it working again.
Thanks.
more than likly it was the point in the motherboard where the flex cable connects. try using some electronic parts cleaner.
i have ran into this a few times and simply replacing the motherboard has only helped a twice, when i cleaned it up it worked.
That sounds reasonable. I still have some Tweek. I'll give that a try. It worked with the same kinds of problems on computer sockets.
Okay. You are on the right track. When I went back to the phone, I actually got two taps out of the screen, which it hasn't done in a long, long time. (I was running keyboard only for a long time before I could take it down to fix it.) I attribute that to just disturbing the contacts with so many assembly/disassembly efforts.
After I applied Tweek to the joints, it ran well.... for about an hour. Trying again was no luck, so I don't think I'm going to mess with the contacts anymore. By the time you figure how infrequently motherboards come up for sale and the cost, I think I'd do just as well with a trade in on a flat-rate repair.
But at least now we know for the record that there is another cause of dead touch screens.
well i have about 13 motherboards, if your interested let me know
Thanks. What has been your experience with changing motherboards?
The reason I ask is because the service manual wants the phone to be tuned again after a motherboard swap. I see a lot of people changing motherboards, and I can't believe that is much of a problem when you don't see anyone complaining about the phone not working well afterwards.
A spare motherboard might be a good idea for a diagnostic tool. It would have saved me a lot of work changing the touch panel and cables if I would have had a motherboard to try first.
I thought I had a good spare in a damaged phone, but when I took it out the other day to test this phone, I found out it had physical damage too. The SIM holder and RF shielding were dented, but the killer was that the daughterboard cable connector was bent.
I suppose back when the phones were $900 you might try to fix something like that, but it's hard enough to do a connector swap on a computer motherboard. I can't imagine that even the factory has the equipment to properly swap the connector even if you can get the part.
How much do you want for a motherboard? On that famous auction site I've seen them go for around $10 to $30. I could kick myself for not buying the last one I saw at $7 because I thought I had a spare.
As we all know, the phone is pretty darn well put together and surprisingly durable. But, unfortunately, it is not invincible. About a month and a half ago I cracked my screen. The phone had a case, but it wasn't anything hefty (the HTC Double Dip case). The phone was still completely usable, but I like the phone and wanted to keep it nice so I decided to replace the screen. I ordered the screen + framework assembly and it was about $55. In the past when I have replaced screens on a few iPhones and an ASUS tablet the parts were quite a bit cheaper, but whatever. My phone is the black model, but I decided to try something different and ordered the new part with red speaker grills. Most guides and such said that the M7 is a pretty hard phone to repair, but I have worked on a couple other phones before, so I gave it a go. After many, many hours of carefully prying apart the phone and transplanting the logic boards to the new screen framework I put it all back together and powered it up. To my surprise the phone powered up and the screen worked fine. (And let me tell you the red and black looks damn good). The first thing I noticed was that vibration didn't work. A bit annoying, but the phone looked good enough that I could get past that. Next I tested the speakers and noticed that at full volume the speakers sound a little bit messed up. Again, a little annoying, but I'm not a professional so I wasn't overly disappointed. Then came the real problem...
THE REAL PROBLEM:
When I put the SIM card in the phone didn't detect it. After a reboot it still didn't detect it. After a factory restore it still didn't detect it. Perhaps the ribbon cable connecting the SIM reader to the board was not all the way secured? After how hard it was to take the phone apart the first time I was not a fan of the idea of doing it again. But alas, the next day I opened the phone back up super carefully so not to damage the new parts. It was thankfully a little bit easier the second time. I made sure the SIM reader was all the way connected, but the phone still wouldn't read the SIM. I pulled the old SIM reader out from the old screen framework assembly and plugged it into the board, but the SIM was still not detected, indicating that the new screen did not come with a bad SIM reader. Has this problem happened to anyone else? What steps should I take? I now have really nice looking M7 that is essentially useless.
So does anyone have input on this?

Same thing happened to me. Also swapped out the old reader without any luck.... Any update on this?
Does it detect it at all? Like ask for the pin code if you use that?
Do you have to disconnect the battery when replacing the screen on this phone? I know on some phones I repaired I had to manually set the current time and date (resets to year 1970 or something like that if you disconnect the battery) to get a signal.
Otherwise I have no idea
Hi,
I really need your help as I have no idea what to do.
After 1 month of using MI5 Pro Ceramic black I have broke my phone,First the touch worked and there was only vertical lines on the lcd in the spot of the shatter so I could operate but due to my stupidity and of force touching the broken glass these vertical lines started to cover all the screen (Everything worked well on the phone..Sound,Camera and etc..)
So I ordered from Aliexpress LCD + Touch screen for about 70$ (Included DHL Express shipment)
When I got the screen I started to disassamble the phone.. Got everything out,Took out the broken screen and pasted the new screen on the frame (Must say all these aliexpress screens are really bad,0% protection on the screen,Not sure about the LCD quality yet but glass is horrible..Started to scratch even before I used it)
Anyways to our point..
Started to assamble back everything.. Powered on the phone and Yay! Phone is working but...
No Sound,Firstly I checked settings and everything..Ran CIT test and everything that belongs to audio giving force close..
Calibrate Speaker PA test results : State-Get impedance failed!,Speaker Vendor-None
Vibration- FAIL no short and no long
Main mic speaker Feedback,Simulation call test,Front mic speaker feedback test,Top mic speaker feedback test,
everything when I enter it giving FC with that details :
"IlegalStateException:Unable to retrieve AudioRecord pointer for SetParameters() blablala...
Headphone mic feedback test (Called on an uninitialized AudioRecord)
So in short..
No Speaker,No Mic,No headphone Mic..
Now my question is what I need to do from now.. Its not firmware/software problem for sure as before I disassambled the phone everything worked well..
My first guess was the problem is on the Sub PCB but then I asked my self..If the USB-C is working and WiFI antenna giving full signal it means the Sub PCB works so what the hell is the problem? I really hope its not something in the PCB it self as it means throw everything to garbage.. ;<
Hope to hear suggests..
I thought to order the MI5 32GB Black version take out the Main PCB put the Pro Main PCB and put also the ceramic back cover but that I would do only if I know that the problem is from the sub PCB but if Headphone mic doesnt work (Which the Main PCB take care of) then its probably in the Main PCB??
Please help!
you didnt damage the pins on the press connector? is the press connector on the ribbon cable flush / fully inserted ? Are you sure you didnt kink the ribbon cable?
I haven't pulled a mi5 apart, but can only assume its like every other phone i have.

The problem is that far as I understood of how the mi5 built and from how I saw it looks like..The Speaker located in the Sub PCB cover,Vibrate connected to subPCB,And all the SubPCB connected with the cable to the main PCB and I checked it connected good and no any damaged pins from what I was able to see..If there was damaged pins then the phone wont get charged as the USB-C wont be connected as it located in the SubPCB however it does work.. So I really have no idea what cause it..
Also the Headphone mic doesnt work in the tests..Anything related to Audio giving that FC with "AudioRecord" error..
I really must to know what causing it so I will know what to do ;<
Little update,
Just connected a bluetooth speaker,No any sound nothing..
Hi everyone! My MI5 has the same problems, no sound, mic, vibration, led buttons light, plugin earphones without notification's icon, can not play music, video offline and online video (Youtube, Facebook, live stream ..). It was happened when i replaced brooken screen. The first time when I turn on, evetything ok, I can play music through speaker, but now everything has gone..! Plz tell me how to slove this problem! Sorry for my poor E!
Hi, I ended up on buying the phone again... It's impossible to fix that problem as probably you did what I did and didn't place the motherboard correctly so a little bent probably happened and that cause to the problem.

Hi there! Care to elaborate a little more? I have also the same problem. I was replacing the rear camera module while the module I had received was broken to begin with. I hadn't really figured this out initially and I tried several times to attach it and test it, perhaps move the flex and retest, and at some I remember I found out the vibration was not there, but didn't pay attention to it as everything was open, until I found out the camera module was faulty in the end, and subsequently discovered also the whole issue with sound/vibration/key backlight etc. Instead of buying a new device, I was thinking to try and fix it, but still I'm a bit unsure about what the problem really was. From what I could figure, I didn't do anything different this particular time the audio/vibration didn't work, with respect to the previous times I attached and detached the motherboard. But is it definitely the board itself and not its flex connecting it to the sub-pcb? Could it be the sub-pcb itself or even both this and the board? In case I buy a new board (perhaps together with a sub-pcb just in case) to replace it which part should I watch out for, not to damage it again. Sorry for the many questions but you seem to be the only source of info for this specific problem.

Hi sorry for late answer,I barley visit xda these times..
After I bought the MI5 again this time in the 64gb version I tested the old 128gb motherboard (The main one) and still same problem with Vibration/Sound (While all sensors work camera too)
Which means its not the sub-pcb problem,Its the main motherboard for sure,Now what cause it?
In my opinion when I pulled of the motherboard to put it on the new screen I insert it in a bad way which made it bent a little and probably the place I bent is where the audio and all the stuff goes on..
I'm pretty sure we cant really do something about that problem as problem related to motherboard it self are usually not fixable,But if you find something I will glad to get a feedback to test on my own bad motherboard so maybe I can back to the 128gb version ;| but I doubt it..

Many thanks for the response! It sheds a little light indeed. I also ordered another phone to replace it as the cost of the motherboard seems to be equal approximately close to a new device. I'm with you, in the same view, I also once placed the motherboard quickly in the chassis without the screw that holds it together, in one of the 50 or so attempts to try and make the camera sensor I was replacing, visible to the OS, and this looseness was the unfortunate one perhaps (?). I too don't expect the sound to work again. I just wanted to double check the issue was not with the sub-pcb, which I did thanks to you. For sure I have no hopes for the mainboard to work again, but still, what keeps me from being certain it is actually the sound card that is the problem, is a very similar case I saw In a foreign forum, and also clues from my device which support the argument that the mainboard might have entered in a kind of diagnostic boot state due to a hardware fault that was apparent, where either some components are not initialized during boot, or their HW resources are taken over from the diag. ports and irqs that are enabled, in which case the issue can perhaps be fixed. For sure whenever I find a good deal on a new motherboard I will replace it, to keep it as a secondary phone, as I liked it quite a bit, but It would be interesting to see if this hypothesis holds or not. Anyway thanks again for the response!
Hi,
I've bought used mi5 with broken screen. After LCD replacement I've found that that phone has problem with sound. Exactly the same as in this thread - no sound, mic, vibration, led buttons light, plugin earphones without notification's icon, can't play music, video offline and online video (Youtube).
Someone already did LCD replacement on this phone and probably done something.
But what I discovered on this phone that problem start when battery charge aprox more then 60%.
I did flash one year old ROM via fastboot ( just to verify if it not the ROM problem) and after that everything was fine ( battery level 50%).
I did hardware test - passed 100% fine.
But when I did charge till 100% the problem come back.
That's really interesting finding... Can you tell me the same steps you did like which rom you flashed and all of that? I will check it with my dead phone maybe if I will have the same thing like you we can point on something...
mi5 lcd replaced touch not working
I bought a mi5 mobile in singapore. My display was damaged. I changed many display in india (checked in many shop). only work display (lcd). Touch not respose. please some one give solution. thank you
have same problem with op
my phone get damaged by water so im rush turn it off and open everything then go to dry it... and problem with speaker etc doesnt work just like op please help i really doesnt have money to buy new phone this month
Exactly same problem with me, just replaced the rear camera and the problem occurs
No sound, no vibration, nav led not working at all, playing video not working
Even playing sound via bluetooth speaker not working too
I believe there is something wrong with the mainboard
can anyone point out which part of the mainboard responsible for the lower board?
The lower board works well though, I tested it using other mainboard

For me the problem was that after the screen replacement (It may also apply to you after you replaced the rear camera..)
When I put back he main motherboard it wasnt sat properly,I put it beneath a small plastic holder and when I closed everything and screw and all..Problem appeared and when I rechecked motherboard I found out it got bent in the right down side and that's probably what killed all the sensors,sound and everything..
Of course that what happend to me..There is plenty of other reasons that may cause to what you experience..

I believe the chip or something similar, that control the sensor, led, vibration etc, was broken because we put it the wrong way
now we need to find which chip it is and replace it
which part of the right down? near the signal cable?

If you just checked and saw you put it wrong as I did,On the little plastic which made a little bent then I guess you lost..I would just buy new motherboard on aliexpress or just give up and buy a new phone..
As you cant really know (I mean from our side..) if its a chip related there or if its the bent it self which made problem on the connection on the board it self..
And yes I was speaking about the right side near the signal cable where you need to install the motherboard from that side where there is a little plastic like holding the motherboard..When I did the reinstall by not checking I put the motherboard on that plastic and after I closed everything and all screws got back I discovered that problem..

yeah, it means it's the same mistake as mine, that little metal thing that hold the motherboard, I forgot to eject the sim card tray and when I pull my main board it was stuck, got a little bent from there
Just wonder if anyone have the schematic for mi5 mainboard, since I'm curious and want to find a way to repair it
Not because I'm in despair of needing a phone, this MI5 is my secondary phone
Just because of the curiousity, that's all

I bought this phone last year to test AT&T's coverage, but am considering promoting it to a more permanent position, so I am finally looking into some of its problems. This phone's camera takes pictures that are clear in the center, but blurry on the left (or top, when shooting in portrait) 20-35%, no matter what. There is a noteworthy dent on the back cover, so the question is if it is more likely that the problem is caused by the bent cover or by damage to the camera module itself. Any ideas?
Either way, you'll have to remove cover, so when you do, take a picture without it. If the problem goes away, it's the back case, replace it.
If not, it might be the camera module, replace it. Either is pretty cheap on Ali, but if you remove the back cover, order a new one. It's almost impossible to remove it without damaging it.
Good idea; will try!

That's pretty much what I was planning after researching things a bit. I'll order just a screen first, then dismantle the device and replace the screen, but hold off on putting the back cover on until test pictures have been taken. I'm excited to get this phone back into working shape!
There's A LOT of stuff you must remove from the screen, speakers, battery etc etc. It can be done, but pay attention.
Report back latter will you ?
Also, when you're putting the (new) back case on it, the top of the device goes first, not the bottom. Don't worry with the USB plug, worry with the power button/IR blaster and the top mic.
Not looking forward to it, but it should be an interesting experience

I'll report back with the results either way. I have seen the videos showing how involved the process is and am not looking forward to it. This should prove to be an educational experience in surgical precision, keeping track of parts, not losing screws, and remembering what order things get installed.
1 down, 2 to go
Screen replacement was a success! :laugh: But wow, that was a lot of work. This has to be one of the most time-consuming screen replacements in the entire industry. As for the camera problem, the issue does persist with the back cover off, so it looks like I'll have to source a new camera module as well as a new back cover (which got slightly damaged in the process).
I'll upload some photos as the project progresses.
Fixed!... but with strings attached
Just to provide some closure for this fiasco, I did finally get the HTC One fixed and reassembled properly. Here's a quick recap:
Following the initial successful screen replacement, I bought a replacement camera module and back cover for the phone (because the problem persisted with the back cover off and because I had ruined the original back cover during the original disassembly). Upon installing both, I promptly reassembled the phone and discovered that the SIM card slot was no good on the replacement screen assembly. Talk about a major bummer!
From here, I was actually able to carefully remove the (shiny new!) back panel without causing any damage and requested a replacement screen assembly. Replacement was the wrong color. Two weeks later, the correct one finally came in, and I went through the (rather convoluted) procedure of painstakingly taking everything off of the screen assembly and placing it onto the replacement... again.
This time, everything worked, (including the SIM slot) so I slapped the back cover on, but was disappointed to find that the volume-down key had come out of alignment during the second back cover install. Also, the vibration motor had worked its way out of place and was rather noisy. For a third time, I ventured back in and managed to get the back cover off without causing much additional damage (there are some small marks on it now, but it still looks a heck of a lot better than it did before) and stuck some adhesive to the side of the motor in order to hold it into the slot better. I also performed the final snapping on of the back cover more carefully.
Finally, the phone is reassembled and fully functional. Camera photos no longer have a blurry edge, but are occasionally blurry either all over or in certain places. It is capable of taking completely clear shots though, which is interesting. Regardless, I've pretty much given up on getting this thing to perfection, and because of the fact that it isn't my daily driver, the camera not working right is not a dealbreaker. At any rate, it seems like finding a properly functioning camera module for this model is nearly impossible. Also, the right (bottom) speaker's volume is now sometimes a little quieter than the left (top) one, depending on the volume. As before, the MicroUSB connection still doesn't allow the cable to plug in all the way, which makes it really easy to accidentally disconnect, but it does still work fine.
With all that said, I've attached a picture of the repaired phone along with a new old-stock Incipio Feather grip casing that I found locally. The Incipio fits pretty nicely and I really like the feel of it, but debris sticks to it amazingly well. Even something as simple as wiping it with a cloth will leave behind a whole covfefe of specs. Liquid baptism and air drying is the only way to fully clean it.
TL;DR? Don't break your HTC One in a way that requires disassembly or repair. Ever. Even if the camera sucks, be thankful that it is fully functional (if it is). If you do attempt a repair operation of any kind, test the SIM card slot and camera (and speakers) fully before putting the thing back together and mind the volume keys as you put the back cover on.
