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.

Camera Cracked Internally & Externally!

Hi,
I have an HTC Desire which is a little over a week old, though on Saturday I got my desire knocked out of my hand and took a fall onto gravel and the battery cover's camera lens cracked and now has a thick crack through the middle which is not much of a problem as it is easily replaceable, though the glass which covers the lens/sensor cracked into many pieces though I do not know if it is a filter of some sort or just some dust protector. (I can still use the camera without a problem).
Should I send it for repair to get the protector put in, or will I be ok just buying a new battery cover?
Thanks!

It's likely not just a filter of some sort, but an important part of the optical design. It could be replaceable, but normally replacing lens elements requires re-calibration of the entire lens itself. I doubt though, that they would replace just a part of the lens, they would likely swap the entire thing. I'm pretty sure HTC buy these lenses/modules already assembled and calibrated from someone who specializes in making such things.

Thanks a lot for the detailed reply! Will be sending to be repaired today. Thanks again

Hi All,
Just for everyone benefit i also cracked the back cover plastic screen and also the glass screen on the camera as well. The back cover is easily replaceable by a new back cover off eBay for £12.99 or the lens piece itself for about a £5 i think, which is easy to find but i decided to replace the internal glass myself. I found this on eBay for £7.49:
http://cgi.ebay.co.uk/ORIGINAL-HTC-...UK_Mobiles_Accessories_RL&hash=item230c703e97
Using an old sack pin i manage to remove the cracked glass, the trick is to prize up the black plastic the glass is stuck too, that way no shards fall off into the camera itself.
I thoroughly cleaned the camera and new glass with an anti-static wipe.
You have to push out gently the four plastic stripes round the camera that the glass fits into so the new glass fits it snuggly when you push it in.
I did make a hash of it to begin with and touched the back of the glass so it was smudged and got a bit of glue on it. I put an anti-static wipe on the needle end of the sack pin and cleaned it thoroughly and this did the trick. To test it though use barcode scanner as well as the camera app.
I haven't much patience and have large fingers, i guess you could take more time and use more precise tools to do a better job but as the camera isn't the most important function for me this was fine.
I did contact the HTC repair shop that was listed on XDA and this was there reply:
Hi,
You’re looking at between £39.95 and £64.95
Thanks in advance

I guess if you have phone insurance that would be a better way to go but as i didn't i saved a few quid doing it myself, it only took 15 mins to do, not hard at all.
Good luck to anyone else who attempts this!

I had the same problem with my phone and I sent it away to redstafford.co.uk and I got it back in about 3 days, all new and shiny... highly recommend!

[Q] LCD and Digitizer/Lens are they Glued together or can i just buy Digitizer

Hello, i had the misfortune to drop my Arc and having removed the factory fitted protector it shattered the glass and became unresponsive to touch commands. I am pretty certain the actual lcd is fine though. I have looked at a replacement digitizer but i am concerned that the LCD will be glued to it which will need a bit more expertise than i have. i have googled and found a video on an x10 dissasembly but even this is vague as to the build of the LCD/Digitizer..
anyone have any experience with this issue or any advice.
thanks in advance

They're glued together. Apparently you can use a hairdryer to melt the glue and separate the components, but needs patience, a steady hand, and a bit of luck...

That is so annoying, i have just bought a digitizer from formymobile . com and i really dont wanna attempt it if they are a whole unit. i got hold of a torx 6 and took it apart as by the service manual that was posted on here but to get the screen off they have a specialist clamp and suction pad contraption..
I could fudge it but i am heavy handed at the best of times..
looks like a 85 pound repair bill from my local repair shop.. Better than buying a new phone i suppose.
many thanks for your advice

Aluminum Bumper Replacement?

I dropped my white galaxy s2 yesterday and it has a semi steep dent on it. Luckily everything is working fine. Anyone know I can get a replacement of the aluminum bumper that surrounds the side of the phone? I've done a a few search and couldn't find it.

Hi Something,
Unfortunately a part like this is usually fused with the front housing assembly on the device. A quick google search yielded the following result...
globaldirectparts.com/Samsung-Galaxy-S-II-SGH-T989-Front-Housing-p/smsng6110920.htm
You'd have to replace the entire front housing assembly on the device...not the easiest part swap, but still entirely doable.
Hope this helps!
Cheers,
Nick

If you do this, looks like you'll have a black T989
Get a case and cover it up, best and easiest option.

That really sucks. I dropped my also on wood floor and cracked the left corner.Great phone but too sensitive. I need a light but strong case.

Any case that provides reasonable protection for a phone is not going to be 'light' or thin. There's a reason why they add bulk and it is to absorb the kinetic energy that would otherwise damage your phone.

Those guys (GlobalDirect) won't ship to an individual, they only deal with businesses.

I had a similar incident happen while out partying for few days straight. A rugged fall onto some ragged asphalt made for some bezel splitting/pitting. I called T-mobile because my phone was "acting weird" and they exchanged it for me no hassles.

I also scratched the hell out of the bumper with a 1 inch drop. I tried using my PHP from tmobile, I was going to use water damage as an excuse but they want to charge me $130 bucks just going to get a case

Is that actually aluminum I thought it was just aluminum colored, well if it is aluminum, you can always try a really, really fine sandpaper ex.1000,1500,2000 even 5000, I had a HTC Sensation (Made Chrome), and I dropped a few times, had chips and scratches which I fixed with sandpaper and 1000 to 2000+Blue Magic. Hope this can help but remember try at your own risk.

I looked into replacing this part when I dropped and dented my phone. Unfortunately, to replace it you have to replace the entire front half of the phone. And unfortunately, the screen is adhered in place. From what I found, you need to have the proper tools (uses heat, I believe) to release the screen, and then reapply it to the new housing. I cracked my OLED while attempting this. Luckily I was able to put it back together and get it replaced under the insurance. Bought myself a case immediately upon receiving the new phone.

Another Shattered display....a few general questions

So, For the first time in my phone career, I have dropped and cracked a phone. I decided to go the route of trying to replace only the glass. There are multiple videos out there, but very few are specific enough for my liking. Let me start by showing what I ordered. It will be here Tue,
So here is the replacement part i ordered.... http://www.amazon.com/gp/product/B00A66UH8I/ref=oh_details_o02_s00_i00?ie=UTF8&psc=1
And to avoid having to use and cut double sided tape, I went with this...but I'm not convinced that it is what i need. I could use some opinions on this. http://www.amazon.com/gp/product/B00BMD8HMM/ref=oh_details_o01_s00_i00?ie=UTF8&psc=1
Its very limited on description, but i think it is basically precut double sided tape for my project.
So, I am going to remove the rear housing but leave the motherboard in place for this excursion. Using a heat gun and the tool provided with the part, I plan to remove the glass from the digitizer.
My screen is completely shattered, so I feel like that may help me a little bit. I can use tweezers to remove the larger bits instead of having to worry about removing the whole screen and putting too much pressure on the screen.
What do you guys think?

I think you have a good chance of success. ...if...
The temperature of the gun is correct.
I've changed 2 screens, and I will not do it again.
The trick is heat and being patient in the repair.
You'll get it. ..just don't rush it. ...g
Edit:
Use a vacuum cleaner with a small piece of tubing taped into the hose end to provide suction in getting any glass pieces you can't see while the repair is under way. ...g

I do this for a living. Be incredibly careful when you do it. I recommend that you pickup a non-contact IR temperature probe, the reason you'll want this is so you don't overheat the LCD and yellow it. Keep the temperature of the glass below 200°F at all times, any higher and you start to run the risk of yellowing the LCD. The adhesive that will remain behind is relatively easy to clean off, just be patient with it and take your time, you can get a clean repair by doing it slowly. As for the adhesive, it's not very easy to not have bubbles, but think of it like installing a screen protector and you should be fine.

One great tool to have for this (and other hot air work) is a thermal camera. If you can get your hands on one great. Be sure to set the pallete to custom and pick colors that will get your attention when they get too high. Set the thing up on a small tripod or something so you can see your work in it and easily monitor the image. I have one where I work but would think of renting one if I did not have access to one and planned such a temperature sensitive job.
