Keypad disassembly guide - G2 and Desire Z Q&A, Help & Troubleshooting

Hi all,
I'm looking for a guide or instructions on how to disassemble the keypad on the Desire Z - I can't seem to find any on Google or Youtube; all those guides cover how to take apart the entire phone - which I have already done - but they don't show how to open the keypad.
Any assistance is much appreaciated.
Thanks!

They probably don't have any guides on how to take apart the keyboard, as it seems to be generally not able to be repaired by itself. You probably would either need to venture on your own, or just buy a new keyboard.

Cheers for the reply; I've looked for replacement keyboards and they sell just the actual pad or its flex cable, but not the whole keyboard chassis.. which means it is serviceable. I just can't find any screws or anything so I'm afraid I might break some plastic clips or such. So I'll still keep an eye out on this thread; I'm in no hurry lol.

Replacing LCD/Screen

So, I had my phone sitting on my work truck and I watched as it slid and flipped over and smacked the concrete. I have a good case and have dropped it before with no repercussions but this time it just shattered the screen. No big deal, hopped on Amazon and ordered a new one for about $24.
Got here today and I eagerly took my phone apart. Followed a video and had no troubles until I got to the step of actually taking out the screen. My evo had quite a bit of adhesive and being that the screen was already shattered, I had a hell of a time getting it out. Well, I seen the LCD was all bent and messed up too but I still put the new screen in and sure enough, half my screen doesn't work.
So...if I order a LCD, take it back apart and put it in along with the new screen everything should work fine again, correct? Also, do I need to order those glue strips or is there something else I can use to hold it all in place. Sorry if this seems stupid but I'm just a little irritated that I ordered one piece when I really needed another as well and I'm just at the point where I feel like buying a new one off Craigslist will be easier. Thanks in advance
Sometimes buying a new one can be better/easier but if you're capable of replacing it yourself why not lol. Just make sure you order the right part for your particular evo......

first, it's hell to get the digitizer (the part you actually touch) attached back on to the rest of the screen. it would be better and easier to buy the whole lcd/digitizer front for the phone.
BUT MAKE SURE YOU BUY THE RIGHT LCD SCREEN: theres two different kinds, narrow strip, and long strip.

Anyone know if theres an easy way to tell which kind of strip you have without having to open up the phone?

I need the same answer but I guess the answer is no
I don't know if there is a way but opening up the phone to find out is really easy. I'd you go to ifixit.com they have the instructions.

Also, does anyone know where to get the best deal on an lcd/digitizer once I find out which one I need?

[Q] HELP! Looking for new keyboard for my Desire Z

Hi!
I've been looking for a new keyboard for my Desire Z for quite some time, but can't seem to find anyone who can supply just this part or even just the pcb membrane (that's the part that's broken).
Does anyone knows were I can get one?
I attached a picture of what i need...
Thanks
Not sure about where one would source just the part but would buying a unit with a broken screen of eBay work?
I've been tryin to look for a unit with a broken screen, but all of them come out pretty expensive since the mainboard is still working... most people sell it for repairing...
Thanks anyway...

Is this what you're looking for at all? Not sure what you mean by pcb membrane.

I'm fairly certain he means the soft platic piece between the keys and the actual mainboard that when depressed makes contact and registers the keystroke.
found this website that sells g2 replacement parts. It seems like a legit website check it out.

The part i need looks something like the attached pic...

Yup that's what I figured, might have to look outside your comfort zone to find that. I'm thinking Chinese website or something lol. I'm sure it isn't a commonly replaced part. Those membranes rarely fail. the only thing they usually need is a cleaning. Have you tried that? Or is it actually torn/broken? If so how'd that happen?
Might have to find a cheap parts desire a on Ebay....
I had the problem when i replaced the lcd screen... damaged the connecting ribbon when reassembling the phone my bad, i know.
i have been trying to find everywhere but no luck, the picture i show is from a Chinese site but they only sell the full body, not that piece in particular.
thanks anyway... if you stumble upon something, please let me know.

Motorola Defy irreversible damage? Please follow.

hi all.
Please, don't shout me! I would like as much help as possible for my damage :crying:. I am concerned, i don't know what else I can do!
Unfortunately, while I mounted the new digitizer to my defy I mistakenly blew up a piece of the motherboard. the piece in question is the power/lock button.
here's how the power and volume buttons are normally presented and my power button is presented on the motherboard.
I looked all over the web for repairing this damage or to buy directly a new motherboard. the problem is that on the web are not for sell replacement parts like this
I also suggested to bring it to assistance putting all the small pieces of broken button inside the phone to make it look like a fault, but it's clearly visible that the phone is half worn considering the new digitizer and the screws are stripped so you can see clearly that was disassembled and tampered...can anybody help me?

It's broken so needs replacement with a new 'tact' switch by soldering a replacement in it's place. I repair similar equipment and know it's possible to do although not a home diy repair unless you're skillful with a soldering iron and can buy the replacement part. I would hope a phone repair workshop could help with this.
Tact switches come in all shapes and sizes so you need to find a suitable one.
Sorry it's not much help.
edit: This site sells them:http://stellatech.com/site_stellatech/motorola-defy-mb525-power-switch-(electrical),a,en,811504.html
and these on Ebay look similar (but only a quess) http://www.ebay.co.uk/itm/10pcs-4-7...al_Components_Supplies_ET&hash=item460b40052a

I never thought of being able to fix something like that The important thing is that one can fix this damage and that's really enough now there's nothing left for me to order those buttons and to solder it on the mobo. I have found those momentary tact buttons that you linked from ebay on amazon.com so I can ship it in my country I have the uncle of my friend who has a soldier station that can do the job thank you so much for the answer, you've given back my hope :victory:
and sorry for my bad english!

When soldering the new part be very careful! - do not heat the pins of the tact switch for too long or you'll possibly damage the new tact switch. These items are very small and the heat from the soldering iron can damage if you keep soldering the metal legs too long. Good luck!

most likely you have also damaged other parts of the board. replacing the power button may or may not fix it.
consider ordering a new/used board from china websites.

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

[Q] HTC Fell Down

hey guys,
a few weeks ago my phone fell down, then I try to turn it back on. the device can be turned on (with htc distinctive sound), but there is no display that appears. ALL BLACK (but phone is working). there is only light at the end of the LCD screen my htc.
anyone know the cause?
IMHO, it might be a hardware issue: a unplugged/broken cable or component.
If so, I would advise you to go to a repair store.
Or in case you feel confident enough to take a look inside your phone yourself, I found this video a few days ago: https://www.youtube.com/watch?v=2Zc0k994Pl4
But such an operation is at your own risk.
If somebody else could give you other things to try out before opening your phone ?
The way you describe it sounds like the digitizer is damaged and will have to be replaced. I think ebay has them for $30ish with the tools you'll need to replace it. If you're not comfortable with that type of project a cell phone store is your best bet.
edit: make sure you purchase the entire assembly (LCD & Digitizer) if you do decide to take this on because having to separate the LCD from the digitizer is a crap job which requires a heat gun and a lot of patience.
