Sliding Keyboard working loose

Anyone that has the xda2s, are you having problems with the slide down keyboard? Mine has gradually worked loose and seems very unstable. The top part of the device rocks side to side , and sometimes gets stuck when opening and makes nasty cruching noice ---- Its starting to worry me, anyone got any good tips?
Thanks
Mike

Just send it to service, not much else to do.

Ok, since posting this i found a topic about opening the XDA2s up and fiddleing around to tighten it up. Does anyone know how easy this process is? Seems quite scary and am not sure whther i should attempt this....

It's only scary the first time. Once you're not a virgin anymore, you'll feel comfortable doing it over and over again. Just don't turn into a slut .
Some things to consider. Use the correct tools for the job. Once the screws get stripped, your SOL. Oh, don't be such in a hurry to take it apart once you get the screws out. Remember to take pics, or if you are good with memory, remember where everything was originally placed. Especially the screws. Had to slap myself a few times for not remembering the screw placement.

i just had my housing recently replaced coz i dropped and scratched it. the keyboard frame + the backside of the front face is considered under warranty. the repair center diagnosed its looseness as "faulty mechanical".

Execellent, in that case im sending mine back so they can fix it! Better than cocking things up my-self!

Touchscreen not working

Hello, I am having serious issues with the touchscreen of my BA.
The screen part is kind os loose, it moves slightly sideways.
I have no idea if the two things are connected, the touchscreen also does not work properly, as it randomly does not detect taps.
I have noticed that if I press for a bit the sides of the screen down onto the back of the BA, it works better for a while.
Do you guys have any clue on what the issue could be and how to solve it?
I myself have the idea that some tap detecting thing behind the screen has detached from the screen itself, and that I have to open it to fix it. Am I wrong?

Up.
Anybody who can give some advise before I take it to assistence?

unfortunatly
i have the same issue...and everybody is telling me i need new screen ..if u get a solution... i'd be grateful if u tell me.thnx alot

Hi, I have disassembled it, trying to understand something, but really nothing happened, I can't pretend much since i am not an expert. i have no clue, that is why i am about to take it to the shop and get it fixed. damn it.

hi..
saw this in another site..hope it helps..
"Are you using a screen protector that has got under the case or could there be a bit of detritus between the screen and the case? These cause pressure on the digitizer making it unable to register taps.
Take off the screen protector and see if any improvement. Fold a piece from a sheet of copier paper at the corner to make a scoop and go around the edge of your digitizer just under the case."

Hardware problem (buttons), please help.

over the past few weeks some of the buttons (namely left soft key, up and left) have stopped working, i've tried numerous roms just incase but it's definatley a hardware issue, now, i've dismanted the phone using the diamantos guide to see if anything jumps out at me, gave the phone a damn good cleaning whilst i had the chance, put it back together....but nothing, everything seems to be in order, all components in their rightful place but i still cant work it out, does anyone know if this is a common problem or if theres a fix as i've been unsuccessful in my searches.

actually, i just found the solution and it worked a treat, thanks anyway people.
btw, if anyone would like to know what i did then i'll be more than happy to share the solution.

please share your solution with us, I have the exact same problem

ok, no problem, heres what i did.
before you start please be aware that this is a very delicate procedure and you should take care as this may naff up your beloved trinity.
ok, i first disassembled my trinity using the dimantos guide located here http://forum.xda-developers.com/showthread.php?t=311463,
now, when you get to the keyboard / button pcb take it out if, you look closely you'll notice theres a thin adhesive plastic cover covering the metalic buttons, very very carefull peel this back (i used a sharp knife to get to it), making sure not to completely remove it, try to only expose the underneath of the buttons in question, you'll see that the buttons come away with the plasic leaving the underneath exposed, now, using a cotton bud and some lightly applied alcohol clean the contacts then when all is done, replace the plastic and make sure its firmly pressed back down you may notice it making a different, kind of sharper clicking noise when depressed than before meaning its worked, repeat for all buttons.
i think whats going on here is the gum or glue from the plastic film has "leaked" if you will, onto the plates meaning theres no contact from the buttons, this would also account for the very slight change in sound when you now press the button.
i found this info here http://forum.xda-developers.com/archive/index.php/t-289737.html

i have the same problem with the front hardware keys. They last around 1 year, i had them changed under warranty the first time but now they are failing again.
Thank you! now i just have check for tools and some courage because i fear damaging my good old trinity.

- I'd like to make your same operation but I'd like to know first if you too have they working on hard reset before trying....
thanks a lot and merry christmas!

yes, even after a hard reset they work for me, its as if it was brand new, bare in mind you may have a different problem so if your gonna try this, TAKE YOUR TIME.

I tried doing this but found no plastic cover above the metallic buttons. Maybe it's because mine went for repair with this problem before, dunno.
I don't think i can mess with the metallic part so i guess i'm stuck with this unless i buy a new keyboard.

it's more of a very very thin laminate, like sticky back plastic than a cover, it should definately be there unless they replaced the PCB with a different model, otherwise the metalic buttons would just fall away. Again, they may have used a different version of the PCB. You can actually buy the PCB and replace it yourself. (here http://cnn.cn/shop/p3600dopod-d810-keypad-p-1825.html )

Replacing the digitizer on the TP2

Hi,
Just purchased a TP2 with a cracked digitizer. I also have the replacement. I've done a bit of research, and it looks like a ton of steps. I'm pretty confident I can do it, so all I'm really looking for is some tips. Any surprises I might see that may not have been covered in this guide? This is what I have so far:
http://translate.google.co.uk/trans...ka/htc_touch_pro2/&sl=ru&tl=en&hl=en&ie=UTF-8

how did you conclude that your digitizer is cracked?

The LCD is fine. It's the top layer of plastic that is cracked. I haven't received the phone yet, but I inspected it, and that's what I concluded. The person who sold it to me is including a replacement part, but I know I'm looking at a lengthy process to dismantle the device.

Do you have to take apart the entire phone just to change the digitizer? I thought you could just hook something underneath the corner and pry it out.
It seems like such a drag if you have to take the whole phone apart to change an exterior item.

Man you're in for a world of hurt and frustration... Easier to just purchase and replace the LCD and digitizer together...
But hey, good luck.....

have you managed to replace the digitizer only? if its such a mission why are so many people selling them on ebay? a scam maby lol?

i too am interested in your results, just now bought a cracked LCD htc touch pro 2 for $100, touching the screen works, except that the phone is stuck in head-set mode and can't seem to get out of it. also, i want to replace the lcd and use the phone myself. can you pls post your success/educational steps which you followed. also, where did you buy the replacement LCD? how much ? pls help.

Totally agree here. From what I have read you dont want to mess around with trying to pry the current digitizer off and then reapply a new one on. It's a HUGE pain in the ass. Just purchase a replacement LCD screen/digitizer combo and i's apparently super easy to swap out.

I've taken apart tons of phones, I'm currently waiting on a digitizer to replace for my TP2. If you search this forum you will find instructions how to do it.
While waiting I've been reviewing the instructions.
As always the hardest part is putting it back together.
The only thing I can recommend to you is to don't worry about replacing it. Take pictures with a digital camera as you go so you can know how to put it back together.
Hopefully I will get mine by this weekend. It is for a T-Mobile TP2 and the only shop to have one available was in Hong Kong.
Good luck.

Hi, can u post how you go with this e.g. is it easy enough to seperate the lcd and touchscreen. Maby a few pics as well if you can.
Cheers

It can be done but it requires ALOT of patience. Take it slowly and try not to leaver against the LCD in anyway. If you do break the screen when replacing it a replacement isn't expensive.

I replaced the digitizer twice. Taking the phone apart and assembling it back is difficult only when you do it for the first time. Once you know what's going on it just takes some time and precision. The REALLY tough part when replacing JUST the digitizer is putting the lcd and digitizer together without any dust or fingerprints in between. I ended up with dusting and vacuuming the room, putting some super-clean brand new plastic bags around the workplace and putting the cold shower on. Then using super-clean glass polishing microfibre cloth and anti-static glass cleaning liquid under really good lamp I managed to get both parts 100% clean and put them back together. Don't forget latex gloves (the ones that leave no marks) - fingerprints are hundred times worse than dust to get rid of. I have no idea how long did it really take but when I finished my back hurt like hell and water was dripping from the ceiling
Separating lcd and digitizer is not too hard. It was easiest when it was still attached to the bezel. I just pried it out applying easy, firm pressure and taking my time. Try not to damage the sticky layer on the edges or get it excessively dirty - it'll make your life easier later.
I hope it goes easier for you. Gud luck!
EDIT: Make sure that lcd is positioned 100% correctly (there is 1 or 2mm space to move it around). It is a very unpleasant surprise to put the phone back together just to find out that some top or bottom pixel lines are permanently invisible (The Voice of True Experience speaks here:/). And generally - keep the place around you tidy - maybe some containers for screws, parts, tools and that sort of stuff. I am not naturally anal enough to start from this point but found out in the process that this sort of job gets extremely frustrating and exhausting when you get confused, start losing parts etc.

It is major hurt! The TP2 is really not user serviceable! Anyway after reading all instructions I still screwed it up. I should have sent it in to HTC. I would not recommend changing the digitizer on your own.
Everything went well until it came to removing the LCD & replacing the digitizer. I cut the speaker cable, and the LCD just came apart. Luckily I have another LCD, looking for a speaker cable now.

has anyone found any places that sell the lcd and digitizer together for the T-Mobile TP2?

Thanks to these instructions I was able to replace the broken digitizer (glass) on my TP2. Unfortunately the Russian instructions stop short of replacing the glass.
Tools required: T5 torx mini screwdriver, letter opener, mini philips, a mini straight screwdriver and I found a very mini (1mm ) straight screwdriver handy for getthing the keyboard and screen back loose. The letter openner and two straight screwdrivers are only for prying
Here is what I did from the last spot on the Russian instructions: (yes you have to do every step)
Note: Be very careful removing the ribbon taped to the back of the LCD. You have to pry the speaker out ot the case up at the top; don't attempt to remove it by pulling on the ribbon. Once the speaker is loose (it's attached to the riboon, you are ok to remove it.
1. Take a small straight screwdriver and pry all around the LCD (metal back with handwriting on it in the last photo.) There are plastic tabs all around it centering it. You can pry gently against them. The LCD is only adhered with a small gasket around the edge of the glass. It is not glued to the screen as was posted by someone else. It comes out fairly easily.
2. Remove the black tape holding down the ribbon connected to the digitizer. I wasn't able to save the tape but not a big deal. Below the tape is one of three screws holding the buttons on. Remove those three screws.
3. Now you should be able to remove the digitizer. Go slow starting at the bottom. It is glued all around at heavily glued at the top. I had the pry the top away with small flat screwdriver and a letter opener. Go slowly and eventually it will release. At the top of the glass is the speaker for your ear. It will likely come off with the glass. Remove it and return it to the now empty case centering it in top.
4. Using gloves to prevent prints remove the protective film form your new digitizer. There is a lot of static generated when you do this so keep it away from everything for a minute while it neutralizes. Then place the digitizer in from the top, feed the ribbon through the slot and press the plastic all the way around.
5. Replace the buttons and the screws that retain them.
6. Replace the LCD; you can't screw it up the plastic tabs center the LCD. Just make sure the ribbon is at the bottom.
7. Reverse the instructions in the Russian link at the beginning of the post.
All told it took one hour the first time. I got it all together and then screen didn't light it. I had trouble reconnecting the screen ribbon during assembly so I figured the problem was there. I took the phone apart (to the end of the Russian instructions) and reinserted the screen ribbon into the connecter and then reassembled the phone. It took 10 min to disassemble and reassemble the phone the second time although I didn't have to take apart the screen.
So that's it. It cost me $22.00 for a new digitizer and $10.00 shipping, which is a lot better than a new phone if you don't have insurance and the phone looks like new. If you look very hard you can make out one tiny speck of dust under the glass but it's barely visible; much better than looking at the large V shaped crack I had before.

Hello!
I ordered (and received) a screen AND a digitizer. But there's a thin scotch tape that make the screen+digitizer (in one piece) get stick to the phone. OK, I teared it off.
But, how can I replace this scotch tape??? Much less of 1 mm thick, it seems to be made of foam...
Anyone can help me???????????
Please....

Coucou !
Is there anybody out there?

I was sent a Digitizer from Ebay (without LCD). Just for everyone elses benefit, there is no way you can remove the digitizer from the LCD Screen. It's glued down. Maybe it wasn't the case with the older ones, but mine can not be separated, no way!
Taking the phone apart is not too hard, the video instructions are pretty good, but seriously, forget trying to replace the digitizer only.
Here is the video:

Cheers, Mal.

If it has the same construction as the HD2, you can put the LCD + digitizer in the oven for 5 minutes at 50 degrees celcius. This was shown in instructions by HTC. Then you can seperate them.

Maybe, but my LCD was glued across the whole screen not just the edges. I'd suggest only buying the Digitizer/LCD combo if you want to do this yourself. If you buy both (as a single piece) the job would be pretty easy.

Replace housing case?

Yeah i bought red one. but you can't do it without a new LCD screen maybe. . My current one is black... changed the battery part once. but still don't know how to change the housing... i hope someone can teach us..

Well, let me try... If you changed the battery, you already know how to replace the backplate, so it shouldn't be a problem. If you want to replace the midframe/housing, that's quite a bit more work, but still doable, if you are comfortable working with heat gun or hair dryer. I would strongly recommend watching some YouTube videos on the subject (phone model doesn't matter; you just need to understand how to work with a heat gun and a suction cup). Also, finding a good disassembly guide for ZL would be useful, to make sure you follow the teardown steps properly.
Note that I personally haven't done a full ZL disassembly, but I know how it's put together, and I have done similar repairs on multiple other phones, including Xperia Z, Z1, LG G2, Galaxy S2 and others. Basically, you need to remove the backplate, then disconnect everything and remove all components accessible from the back, making sure not to damage ribbon cables in the process (some of them are very delicate). This is where a good disassembly guide comes in very handy. After that, you are left with the most difficult task: removing the display/digitizer assembly without damaging it. You need to carefully (that's the keyword here!) heat it up around the perimeter to loosen up the adhesive, and carefully pull it from the housing with a suction cup, working your way around the edge with a plastic spudger, or a guitar pick, or a similar tool. At this stage, you can quite easily break the glass, or split the LCD/digitizer "sandwich", so, again, be careful!
If you have no experience whatsoever doing this, your screen's chances of survival are quite slim. I am pretty handy with electronics and with stuff in general, and literally spent years with soldering iron in my hands. Still, my first two attempts were fudged up (the screen was already damaged in both cases, so no harm done, but lessons learned). First time, I fried the display with a heat gun. Second time, cracked the glass trying to separate it from the housing. That was enough for me to learn the tricks. So, be prepared to replace the screen, if you break it. But hey, you may very well get lucky, and do it right the first time around...
Assuming you are through the disassembly process, you will then need to put the phone back together in your new housing, using two adhesive gaskets: one for the display, and another for the backplate. I would recommend buying the proper pre-cut adhesive for your phone (check out Amazon or eBay), but you can also use a narrow high-quality double-sided tape (3M or similar), manually cut in place.
Good luck!

Tried googling up but it seemed that there are no guide for changing the housing for xperia zl.
But oh well, maybe I need to buy the lcd screen just in case I failed. But thanks! That'll boost my spirit up to do it
