[Q] Replace the keypad - Touch Diamond, MDA Compact IV General

I've been trying to replace the whole housing of my diamond which has resulted in good results untill now.. Only thing im having a little trouble with is the keypad.. The plate it self needs to be glued on to the print somehow.. Does anyone have any suggestions on how to do this ? I got the plastic keypad it self and i've using some tape that sticks on both sides but due to the thickness of the tape the keypad is not smooth with the housing (it sticks out) ..
Any suggestions or guides ?

keyboard not working after disassembling

i recently disassembled my tilt to find out if i could tighten the hinges because the hinge were loose but ended having problems with the keyboard. i hooked up the wire that connects from the keyboard to the motherboard. now the problem is that i could only use half of the character.
do you guys encounter this kind of problem? and did you guys fix it?
thanks

Buy a new keyboard with flex cable on ebay.
I replaced my tilt keybard (with silver keys) with the original all black keys.
The keys, the flex cable, the board ~ everything is one solid peace that's soldered and glued together, it's not removable (without damaging). The flex cable is actually sensitive and can break. If you try to mess with the keyboard, putting a lot of pressure on the silver part under they keyboard, or make a dent on the silver part under the keyboard (in the effort of trying to separate the keys and the board, which is impossible) ~ you might end up pressuring the flex board/wires and cause only half of the keys work and half doesn't, and the cap-lock and func light won't turn on.
Remember to get the keyboard with the whole frame and flex wires and not just the plastic keys by itself.
The whole black rim, flex cable/board and the silver bottom piece is all soldered together as one solid piece. The plastic keys are like sticker, lay on top of the board and flex.
(your board and flex seem broken anyway, but...)
If you only buy the keys without the whole board together, you will have to rip out the old plastic keys layer (because it's just a layer of sticker on top of everything) ~ do it carefully, or you might rip out the flex cables/board by accident.
Let me know if you want some pixs that I took when I replaced my keys.

Wad there possibly a alternative from getting a whole new board as i only replaced the screen mine.............
I had a similar problem when replacing the screen on my wife's Tilt recently. I took it apart a second time and put it together again very carefully, particularly with the small ribbon that connects to the motherboard, as I believe that is the ribbon that connects the keyboard to the motherboard.
Take a look at this video to see the part I am referring to: http://www.youtube.com/watch?v=96iXd5jG2-U#t=2m45s

**~htc touch screen not working!!!!~**

hi,
my touch diamond 2's touch screen stop working randomly ( i think that i applied too much pressure on 1 spot for too long). I can see the touch screen dots on the area. I am just wondering if I were to repair this, would i be replacing the DIGITIZER or the TOUCH SCREEN.
Thank you soo much
warranty might cover that. It might not be your fault
I have decided to fix the part myself since I do not wish to ship the part to their location in the US. Any idea if its the digitizer or the LCD screen that i should be replacing?

Search the Wiki, there are dismantle instructions.
I had the same on my display, and was able to move the dark spot to the edges where it disappeared.
I moved it with scratching it with my nail very gently applying some pressure.
In Europe HTC offers a pickup and return warranty, is that different in the US? If it is the same I would send it in to HTC for replacement, since it might happen again pretty soon....
I already have 3 screens replaced :-(
jason, did u manage to fix this? i have the exact same problem and pushing the "bubbles" towards the edge of the screen didn't help. my screen is still unresponsive..

Try applying duct tape to it repeatedly until you get it back.
Yes, both
I recently replaced the Touch Screen on my Diamond 2. Same problem; spots that "stick" in the middle. I used to solve this by running both my thumbs down the sides of the screen to "puff up" the low areas in the middle.
The part you want is actually called a "Digitizer Touch Screen" on eBay, cheap too. Prepare to spend about 2 hours fiddling with very tiny screws, connections and glue to tackle the job.
The hardest part for me was actually getting the Touch Screen to work; it seemed to be calibrated in mirror-image AND turned 90 degrees sideways, which made getting to the calibration functionality an extremely frustrating experience. I spend another 3 hours on that, but now I've got a perfect phone again, since I ordered a new case as well. No use taking the entire phone apart and then rebuilding with a molested outer shell...
maybe you should reset it
Working Solution Till Now
Hello Friends,
I have TD2 mobile and today I had same issue. I was thinking it was because of the weather or some.
I remember it did happend several time before, but when I restart the device several time it does work. So I was ignoring.... But today it did not work.. looks like going toward end... So I did soft and hard reset without and that did not helped me.
So I switched off the mobile, "heated" the touch screen gently with my hand for 1 min and started the mobile again and it worked for me .
Not sure if this is a solution, but will work.
May be I will contact Service Center here in Hyderbad and see what is wrong here?
Hope this will help you all...
Thanks.
Solution
Okay, I've just had this problem with an HTC Touch, and I think this works with any HTC that has a "digitizer" rather than an all-in-one touchscreen (I think newer phones have digitisers).
I'm not sure if this will always work, but I've just done it - sometimes the inactive touch screen is "broken" because the layers are stuck together (so the phone can't tell where the touch is, hence unresponsive). With mine, I looked at the screen side on and could see a kind of "oily" patch in the light.
The solution is to get masking/gaffa tape - the very sticky brown one. Stick it down on the screen/digitizer and then keep pulling it off - this pulls the layers from each other. I kept repeating this lots before it worked - and in the end I pulled the top layer completely off (I think you should pull from the top of the phone, as the layers need to be attached at the bottom of the screen/digitizer). Once it pulled away, I gently lay it back down (after panicking!!) and hey presto it started working again.
Good luck!
Digitizer replaced but still not working
The touch screen on my Touch Diamond2 stopped responding to my touch (or the stylus) and I tried everything including removing and replacing the digitizer bus just in case the connection was the issue. But all to no avail. Finally I decided to replace the digitizer (touch screen)
The problem for me is that it made no difference. The new digitizer doesn't respond to my touch either. The problem is apparently somewhere else.
If anyone has encountered this problem and has a solution I would be grateful to know what it is.
Thanks in advance
Replace the Touch Diamond2 Digitizer touch screen.
I recently replaced the digitizer (touch screen) on my HTC Touch Diamond2. Since I found on the net, no instructions for replacing the actual digitizer, I thought I might include some here.
It was relatively easy to fit. The only difficulty I encountered was a lack of information about how to actually remove the old one. The various instruction sets found on the web all stop once the screen is removed. But the digitizer is not covered by these instructions. The digitizer is bonded to a thin glass immediately under your screen protector (if you have one fitted) and after the screen is removed following instructions you will find on the net, the digitizer and the thin glass sheet that it is bonded to must be prized off from the front of the housing. The digitizer separates from the glass easily, but the glass is securely bonded to the housing with a silicon glue. It must be prized off by gently lifting a corner and applying a little upward pressure allowing the glue to slowly and gently let go. Don't be surprised if the glass breaks during the process. Once off it is a simple matter to press the new one in place. Just remember to start by slipping the connector bus (cable) through the narrow slot between the metal outer housing and the inner components. I used a set of tweezers to poke it through. DO IT FIRST before pressing the digitizer into place.
Okay, as I said the process was easy and took about 15 minutes all up.

Thanks for the heads up on the glass part mate. Just replaced my TD2 digitizer too. Kinda freaked out at first when the glass split.. haha
Anyway, just wanna 1 more info. When removing the old digitizer, it'll be easier if the front housing was heated first (with a hairdryer on full or a heatgun) to soften the glue. It'll be easier to remove afterwards.
Word of warning though. Only head the housing when REMOVING the old digitizer, DO NOT use this method when applying the new one. The digitizer dies because of heat. Heat is what causes the newton rings issue.

Shoofty, did you manage to fix yours?
Thanks in advance,

Fixing TD2 touch screen
TD2 touch screen is a common problem I guess.
Symptoms are :
1- Touch screen does not respond sometimes
2- You can see a grease like layer under the touch screen
3- Sometimes if you look closer to the screen at some part you can see a a liquidized small area.
Solutions:
1- If you see the liquidized dot on the screen turn off the display and try to rub it with your finger until it disappears. turn it on again and try if it works. I guess heating with the finger as other peeople here suggest does the same thing. However this is a temporary solution. Your touchscreen will die at some date. I used my TD2 for 8-9 months using this method. But at the end touchscreen died.
2- Replace the digitzer or complete frontcover. Actually this might be easier than you think. I replaced mine in half an hour. I bought a front cover which includes the digitzer (http://www.ebay.de/itm/Original-HTC...zer_Ersatzteile_Werkzeuge&hash=item4cfe6f78dc) and openning tools from ebay. Dimanıond 2 disassemble and assemble videos on youtube were very helpful. I strongly suggest to buy the complete frontcover (inc digitzer). It makes replace process much easier and gives the device a brand new look. My old front cover was worn from the corners (which is also very commpn problem of TD2). Now it looks brand new. No strach on the display and body.
Thnks Ozkarah.
I happened to realize that, surprisingly, the touch screen of my HD2 started working if I heated it up with a hairdryer. So, I think something else is wrong beyond the touch screen, probably the connector to the main board of the mobile. It might expand once it is hot and that is why it starts working. In any case, I think that is beyond repair

Hi,
I have same problem when I changed new screen (screen is calibrated in mirror-image AND turned 90 degrees sideways).
Could tell step by step how you get your screen calibrated?
Thanks

Help with my funky digitizer

Hi there. A friend of mine gave me a G1 with a cracked digitizer. I ordered a new digitizer from ebay, and after it arrived today, I installed it. I then powered on the phone and found that the lower ~8mm (in vertical orientation) of the digitizer is unresponsive.
After futzing with it in the maps app, I noticed that if you start your gesture where the digitizer works and drag across the trouble area, the map shutters and shakes back and forth as though it were getting input from all directions.
Has anyone encountered this? Any possible solutions? I'm stuck
Ugh, I thought the digitizer wasn't seated properly, so I dis and re assembled and the issue persists. Is this a defective digitizer?
It's really distressing not being able to use that lower portion. Any help would be appreciated greatly.
Hehehe. User Error
For anyone facing this in the future, the ribbon connector at the top of my digitizer was bent slightly, as it could not sit flat because of two of the little rubber bits near the top. Remove rubber bits (like the manual tells you too ) and refit the digitizer, then refit the rubber bits and continue reassembly. Fixed
I feel so stupid.

Theory on source of the screen lift issue and possible wedge fix

The washer fix resolved the screen lift issue for many, however I've noticed that something doesn't quite add up. Using the washer fix mysteriously resolves(or partially) the issue of a springy/spongy left screen and the creaks and popping noise. The theory was that the screws was too long and tightened too far with the ends of the screws pushing the glass screen out and pulling the plastic silver bezel back.
There isn't a reason to why the springy screen or strange noises was fixed and neither a reason to what the cause was. Besides resolving those issues some people found it hard to push the back cover back on and still have bulging back covers and also bulging silver bezel. You might get away with this issue by putting washers on the two centre screws and taking out the washer on the top part of the screen. I believe this worked because the height of the screws gets elevated with the washers and pushes against the back cover and denting and marking it in some cases. If you managed pop the cover back on the increased pressure from the screws makes the plastic tabs pull on the silver bezel and warping it (maybe).
I thought maybe the culpit of the screen lift might not simply be long screws. But I didn't understand how the washers fixed it. After looking at iFixit teardown pictures I saw something else that could push down on the LCD unit and onto the screen. On the second picture of step 12 I can see large cut outs in the metal frame and on the back side of the motherboard I can see taped components. I thought it might be possible that the taping left creases and air bubbles on the pcb and the bulging of the taped components looks like it can press on to the LCD unit directly underneath. The cause of the popping noise and sponginess came clear to me now. The popping noise comes from the tape being pressed against it (it could be glue from the screen/bezel too) and the sponginess is probably the PCB bending .
I think what the washers did was lifting both the metal frame and the pcb up and the taped components underneath didn't press against the LCD unit anymore. This created screw elevation for some people and back covers can't fit back easily as I mentioned.
I didn't want any screen lift, bulging back cover/bezel. I thought maybe I can lift the pcb up without putting washers in and I thought of just wedging the pcb against the metal frame right next to the screws. I don't recommend anyone to just try jamming stuff underneath the pcb without checking out the pictures and have a plan first. There are components underneath and please don't push anything too far in. I've tried putting plastic blister underneath the pcb in between 4 screws and next to the 4 pin connector. They are just longer rectangles by the way and I trimmed the ends in the same way as the washer method. However the screen still bulges a little around the centre where I can't put wedges because of the ribbon cable. The bulging back cover problem is completely gone however. I think I will try to put one washer for the screw above the ribbon cable, because I can see that the pcb has a screw hole right under the ribbon cable near that screw. This should lift the pcb a little around the centre. However I'm going to put a thinner washer as I don't want the screw to get elevated too much.
Anyone thinks this theory is rubbish, or have something to add?
EDIT: I report success! Instead of typing out the same thing I will show you with pictures. No idea if this fix will last, no guarantees. I still have a little sideways bulge but my N7 is so close to being perfect now. I don't think I will change anything else for now.
it's from that black foamy piece in your photo....this was mentioned in one of the other threads....
