My speakers had become distorted or blown so i bought 2 replacement speakers, i took the phone apart and replaced the lower speaker but when i got to the top speaker i noticed that i had received the wrong speaker. As i wont be getting a replacement speakers for a few days i decided to part reassemble the phone , all ribbon cables have connected, have replaced some but not all of the screws and slightly replaced the rear case but not fully clipped it back in place as i want to be able to easily remove it again once the top speaker has arrived.
Upon powering the phone on i have notice that a certain area of the screen doesn't seem to be responsive any more, it seem to be a vertical area going down the screen where the 'W', 'S' and 'Z' keys are on the keyboard!. Is this because i haven't fully reassembled the phone or have a buggered part of the touch screen when taking the phone apart?
Have downloaded the screen touch test app from the appstore and ran my finger over the screen and you can clearly see where the screen isnt responding....

most likely the digitizer is damaged or the flex cable is damaged

Really? seems odd as i didnt have any real issues after getting the case off, everything else came apart easily so not sure how the digitizer or flex cable would have got damaged. Is the digitizer easy to replace?

I don't know if you replace the entire led + digitizer + glass all in one or not .. I have never disassembled the phone.
did you have to unhook the screen from the Motherboard ?

Errr yeah that was a ribbon cable that came from the digitizer/screen to the main board...maybe its just not correctly inserted back in the socket. Odd thing is if i touch the area that seems to be unresponsive i can still get the screen to scroll up and down, just doesnt want to seem to work on the keyboard, If i try and press either the w, s or z keys it just presses the key next to it
Yeah this phone doesn't take to being taken apart very well
It sounds like you damaged your parts disassembling or reassembling the phone.

Suddenly yesterday I can't insert the stylus in its place to the end. It stuck before it's fully inserted in my Diamond. Trying to explore the problem, surprisingly the RED dot of the reset button is not there. I'm going to disassemble the lower part of the phone to see what the problem is. However, I'm trying to find the lost reset button, but I'm searching for something that I don't know what it looks like.
Can someone be kind enough to post a photo of the reset button while taking the battery cover off?
Thanks a lot.

Thanks you so much foryour swift reply. I'll start searching for it.
Mean while I founf this page for dismantling it but the part I wanted it's not clear as your photo. http://www.pdacenter.ru/razborka/razbor-htc-touch-diamond/index.html
Thanks again.

As you probably still have waranty you shouldn't disassemble it yourself. Bring it back to the shop you have it from and have them repair your device.
I Fixed It
Finally I was able to fix the problem. Thanks goes to SecureGSM for posting the photo.
After comparing the the photo to my phone and other photos I downloaded it form http://www.pdacenter.ru/razborka/raz...ond/index.html, I knew what was wrong and I'll try to explain it for the benefit of everybody.
What happen is that a small magnet piece (responsible for holding the stylus) is glued to the phone. And somehow, the it was pulled by the movement of stylus (in & out) and was stuck on the reset button and hide it. !!! very strange.
I had to dismantle the side plastic bar (where the stylus goes in) and re-glued the magned in its place. Then finally assimbled everthing back again.
I just can't believe that the the magnet is fixed with a very weak glue that goes off in less than two weeks of use.
In the attached images I tried to explain how I did it.

Thank you very much for your description of this problem. I experienced the same problem today with my stylus and saw that the magnet was sticking not on his place, but somewhere inside the backside cover.
I only want to know from you if you removed really all the parts inside the diamond to reach the original place of the magnet? Or is it enough just to unscrew just the 2 screws of the steel plate of the stylus holder?
I have fixed it now without unscrewing anything. You just need small fingers and much patience!
Of course it's better to use a new glue strip, but I used the existing one...
I will see how long it works till the magnet is again placed anywhere in the cover
Hopefully this will not happen again! You just have to watch out, not to use the stylus outside on the right side of the diamond.
I never knew the diamond had a soft reset button till now atleast
On the matter of build/assembly quality - is anyone else finding there pressure sensitive Enter/OK/Select (or whatever you want to call it) key slightly going deeper into the groove of the panel [Home,Back,Answer,End panel)? Mine is no longer sitting flush with the panel and I can feel that it has been 'pushed' in.
Hi guys, as some of you may have seen my earlier post about my problem with the USB port, here is some guide on how to replace it.
This is the link to my problem with the USB port:
http://forum.xda-developers.com/showthread.php?t=1634683
Surprisingly enough, by simply changing the USB flex, it will fix the problem.
The USB flex looks something like this
http://www.parts4repair.com/htc-incredible-s-charging-connector-flex-cable/
You can get it off ebay with the keyword 'incredible s usb flex'
As you know, when you do this your warranty will be VOIDED
First of all I take no responsibility if you device is damaged, you get hurt during the process, or your dog eat your phone, etc etc. Do this on your OWN RISK
Heres the guide on how to open the phone:
http://dl.dropbox.com/u/68923799/HTC%20Incredible%20S%20Dissassembly%20-%20Reassembly.pdf
Here is some quick guide on what is relevant to changing the usb flex:
Tools that you need:
-Torx Screw driver T6 (* screwdriver)
-Phillips Scew Driver 00 (Its a really small + screwdriver)
-Tweezers
-Anti static wrist strap
Procedure:
-Step 0 wear the anti static wrist strap
-First remove the battery cover
-Pull out the batter,SIM card, and microSD
-Remove 7 torx screws

-Open the housing, this can be a little but tricky, just make sure you are gentle with the side, and NEVER pry from the USB port. You might also wanna check for some latches around the phone, make sure you loosen it first before crack open it.
-Remove the volume rocker plastics and the usb housing shield
-Next remove 2 phillips screw on the motherboard (Make sure you remember the position of the screw on the left picture, the first time i did, i put the screw back in the wrong hole)
-When you remove the phillip screw on the right, the headphone housing will come off, make sure you don't lose them.
-Take out the vibrator (you don't have to disconnect them, just remove it from the housing)
-Remove 2 stickers on top of the flex connector
-In the picture above, I indicated the flex connector lock in RED circle. Lift that lock upward very gently, then pull the flex out of the connector. (total of 2 locks and 2 flex)
-Next lift the motherboard, this can be tricky, make sure you lift it from the top side of your phone, and wiggle the motherboard gently toward right direction. The thing that secures the motherboard the the chassis is the housing of the vibrator. Do this carefully as motherboard is a bit fragile.
-Next flip the motherboard around, you have to be careful, there is a flex that connect the lcd to the motherboard, you don't need to remove them, just flip it.
-After you flip the motherboard you will see the usb board, just remove the sticker, unlock the lock, remove the board, replace it with the new one.
You are DONE! Reverse the procedure to assemble and you are good to GO!
If you follow all of my procedure, the only possible problem that you will have is:
-Black screen (The long flex is not secured tightly)
-Home,menu,back,search button didn't light up (The short flex is not secured tightly)
If you have any question just post a quick reply or PM me
Hope this post will help some fellas that have a problem with USB port, if you like it please hit the thanks button.
So...after flapping about for over a year I finally got around to fixing my old HTC. It worked a treat...charging properly and being recognised by the computer again...but THEN, after 3 days of perfect operation, the bloody touchscreen stops responding....new messages pop up and sit there taunting me while I swipe about to no avail.
I've tried few things suggested by the internet, including the one where you hit the screen corners, but no luck.
Is it possible that ive loosened a connection somewhere when I changed the USB flex or is it just a really annoying unrelated coincidence and I should just accept that my phone had reached the end of its life?
I got bored and my battery was having issues where it doesn't update correctly on the status bar so I decided to open the tablet up.
Everything seem to be in place and no loose wires, Here we go. Attempt this at your own risk.

--> Remove the screws in each housing where the dock will go. Be careful the screws are very small.
--> Stick that screw driver in there. after removing the screw, use the screwdriver to push on the screen upward from inside the housing. Push gently.
And you can go along the screen with a plastic prier to lift the rest of the screen. Once you done that
--> Here's the inside.
--> lift up the white strip tab to remove the cable. Be Gentle ( located on the left side of the tablet )
--> Lift up the black strip tab to remove the cable. Be Gentle ( located on the back of the screen )
--> removing these cables will disconnect the screen from the tablet itself.
--> A interesting find. The metal housing where the dock goes was loose when i opened up the tablet. (I dont have a dock yet) so the housing was loose out of the box. This is probably what was causing all the loose locking mechanism for the tablet and dock. (Dat arrow)
Terrible quality control by Asus :|
Wow, I could have used this about 24 hours ago. I ended up just winging it anyway, I was actually regretting not taking pictures so I could post a teardown like you just did.
I was also going to post the possible WiFi fix I attempted. When the tablet is opened up, there are four little springy tabs (pogos?) on the top right corner of the motherboard that connect to the screen when assembled (two for WiFi, two for GPS). My suspicion is that they were not connecting fully from the motherboard to the back of the screen. I had been having problems with WiFi dropping out which coincidentaly started around the time my tablet developed screen click. In an attempt to fix the screen click, I pressed firmly around the bezzel which I suspect pushed my pins down far enough to create connection issues.
What I did was simply stretch the pins back out towards the screen contacts. It did seem to help a little bit, but I have been brainstorming a better way to ensure contact.
All that being said I am no developer. I got the idea from here http://www.youtube.com/watch?v=vgx2Kpfi-Ps
Also, I take no responsibility if you try this method, and break your device.
Hey, looking for some help.
Basically I have an M7 (been happily married to it for nearly 4 years) and cracked the screen on it a few days back. Looked at some teardown videos and decided that id have a go at replacing it myself (new screen of ebay for £16, why not? Also decided that since id have the phone open I would swap out the camera module to try and rid myself of the purple). So long story short, i stripped it down, done everything I needed to do and assembled it all back together again and now when i press the power button nothing happens.
Tried holding it in for 30+ seconds, tried it with vol +/- buttons
When plugged into charge nothing appears on screen and no LEDs at top
When connected to laptop it registers usb connection but doesn't appear in device manager
Wondering if anyone could suggest some 'common' problems during rebuild that may be preventing it from powering on? I have been around all the ribbon connections, they all look good. The wires from the daughter board are all reconnected in their right places, the battery connection is plugged in, the power button too.
Any suggestions welcome
Update- okay so I've upgraded phone and this is still just lying around and I'm keen to get it going just for my own satisfaction more than anything else. The position I'm in now is that when connected to charge the screen displays the charging symbol and %. So my conclusion is that the screen in fact works and the battery is connected. So my next thought logically would turn to the switch? If the switch is busted this won't allow the phone to power up but is there a way to bypass the switch and see or do I just need to replace that part and see what happens?
Am I also corrected in assuming that if the battery is charging and showing the symbol and percentage that the motherboard is working or would it show that even if the motherboard was compromised?
Again any advice will be appreciated

I'm also thinking of a bad power switch, maybe the flex cable? Battery charging is handled by the recovery kernel so I don't see any reason to suspect a bad MB atm. It's always hard to help ppl in your situation, without being able to see the device. It can be anything that was damaged during the repair Afaik, there is nothing you can do to power on the phone without a working button.

Thanks for your input. Glad im thinking along the right lines at least. A new switch is only a couple of pounds so i'll take a chance on changing that if you reckon that the rest of the components should be in working order. I'll update on the outcome
So a new power switch was not the answer
Just trying to think where to look next. Sorry im still pretty much a noob when it comes to the actual inners of a phone but ive taken a photo and circled areas where I suspect there may have been damage.

The small silver wire to the right of the camera unit, not sure what it does but it looks to be a link between the MB and DB. Pretty sure i kinked that while rebuilding.
The big flex to the left of the camera, this looks to be the main link between the MB/DB. Not sure if this is damaged but ive highlighted it as the outer edge is a little rough (not sure if this would be enough damage to stop it from working?)
Finally there is the bottom left flex. The one in the middle above the main battery connection. I done a little damage in the teardown and broke a bit of the clip (again not sure if this damage would stop it from working since the contacts seem to be fine). Not 100% on what this flex does but it looks like it serves the bottom end of the phone (usb terminal, mic, speaker etc...)
Once again all input welcome and appreciated,

Could be anything like a damaged cable, connector or even ESD damage. Btw I don't really understand why you didn't mentioned your damaged cable/connector before, I would replace parts that I know they got damaged during the repair before trying other parts...
Don't waste to much money on this, you can find the M7 for less than 100$ on ebay
I've noticed these lines appear on screen when my finger touches it. Horizontal lines appear, they seem to actually be in a fixed location, fading away after a second of no contact and then reappearing in the same location.
I have tried:
Restarting
Booting into safe mode
Remove screen protector
Changed screen brightness
Went into developer mode, there was a setting there to show where you press and it was turned off already.
Anyone know what on earth it is?

This must be a hardware problem. If you're still under Huaweis warranty, send the phone in for repair.
Hint: print the photos you made and put them directly beside the phone, so the repairman can see the problem.
I had the exact same problem and they disappeared after a couple days.
I noticed that this lines appears after I activate "glove mode", but when I disable it, reduces the lines. Only stops this "bug" after a restart. Verify if you have glove mode on (settings > smart assistance > glove mode)
I got this problem too. Very rare and I think it's a hardware thing.
A colleague of mine made the screen do this when touching it but if I did the same nothing happened. The effect (he had) on the screen went away after a few tries.
I blame it on static electricity but might be something else...
I have a similar problem except I have 3 faint white vertical lines running down through my screen, barely noticeable though, so im not sure what the problem is
?
Anyone have further information? Im worried sick because I got this problem a couple hours after puting a "smart case" (cheap knockoff) on the device (has a magnet on the back and on the side) and a "glass" protector. I'll remove these for now and see what happens.
UPDATE: I'm almost certain it had something to do with my cheap screen protector (I haven't removed it tho). In any case, it took about two weeks before these lines seemed to stop appearing. Haven't seen them for 2 or 3 weeks now.
Electrostatics

White stripes (or lines) on the IPS displays appear as a result of electrostatic voltage. This problem has been confirmed for a number of smartphones other manufacturers: Huawei P10 Pro, Sony Xperia XZ1 and XZ2, HTC U11 and U11+.
for example, Sony says:
Sony Mobile is committed to providing the highest standard of product quality and customer service for all of our products. Due to the characteristic of the display, you may see stripe patterns as a result of electrostatic in some models. This is not a functional defect and usually the stripe patterns fade away as the electrostatic disappears.

"Electrostatic voltage is still just voltage. Materials that can store electrostatic charges are insulators (or are insulated by something), so the charge cannot leak away."
IMAO, this problem is not a global one, but it seems to me that it is related to hardware defects in the assembly of smartphones.
