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.

Screen replacement 10.5 ??

I stupidly cracked my screen and took it to my local fix it guy. He wasn't familiar with the tab but did several other Samsung tabs. He said I had to order the LCD along with the screen which didn't sound right. He said the screen is glued to the LCD and is very difficult to remove without breaking. I've only personally fixed ipads so im not familiar with the inner workings of Samsung tabs but from what I see all I need is the screen and digitizer. Tablet works perfectly fine. Buying an LCD will be a lot more expensive than the $70 screen replacement. I went back and asked his assistant which gave me the impression he know anything, since the screen is amaloid is there an LCD? If the tab works do I need an LCD as well??

AMOLED screens are a large group of single LEDs. There is no liquid crystal portion. It is possible to replace the glass by itself but it's extremely hard. Most places do it the way you listed and buy them as one piece. It requires a heat gun and lots of patience to change just the glass and it's not unheard of to break the screen or digitizer in the process of removing the old glass. Look it up on YouTube and you'll see what I'm talking about. The screen digitizer and glass are made into a single piece to keep it thin. Makes it more expensive when you need to fix it but they are MUCH better screens than LCD as far as blacks and power usage.

Damn it he actually knew what he was talking about. This is the first screen i ever broke and of course it has to be the most difficult. Saw a LCD screen combo for $260 but I'm just gonna give him extra to try and save the current LCD. Thanks for the info
I just watched the video it didn't look too difficult it was actually separated in 2 minutes in the video. After Applying heat it separated rather easily. An experienced person shouldn't have a problem.

The glass being glued to the screen has nothing to do with it being AMOLED. Several non-AMOLED tablets and phones (e.g. iDevices) have glued screen, digitizer, and glass all into one piece. The reason is to make the device thinner, lighter, and most importantly, cheaper to manufacture.
A heat gun will melt the glue and you can then take it apart, but yes, it's hard and you'll likely break it.

It might be removable if careful but gluing them back together will be difficult without introducing air bubbles or getting the glue in the wrong place.
I would send it to samsung, you may be suprised and cost less than you think.
I smashed the screen, damaged the metal housing and speakers on my HTC ONE M8 within 2 weeks of buying it. I sent it to htc and they completely fixed it in a week and looked like new.
The total cost of the complete repair including 2 way shipping was actually way less than the total cost of just the replaced parts if id have bought them myself. It cost me £103 in total for everything to be good as new and that was a phone that was supposedly almost impossible to repair.
Maybe Samsung might be as generous?

I'm actually going to give them a call because I know it'll be cheaper than buying an lcd screen and labor. Thanks for your post

Just called Samsung and they quoted me $200 with free shipping to and from. Which is excellent because that's cheaper than I've seen for an LCD and screen. These are my options so
1. $25 for screen and $50 labor for local guy to fix with no guarantee he won't break LCD then I'll be back to square 1
2. $199 send to Samsung guaranteed to work like new when I get it back.
#2 seems like the smarter choice.

Not only that, but quite often these cheaper non genuine screens have problems. Plus you'll have some of warranty for the work.

Your absolutely right, OEM is always better.

[Q] Screen Shattered

Hey All.
Been using nexus 7 2013 since last 2 years. My nephew dropped it and the screen cracked from the side. The device is working fine. The touch doesn't work at the the area of the cracks on the top right, and a few other places. But works everywhere else on the screen. My question is what has to be replaced, the digitizer or the entire LCD. My personal diagnoses is only the upper glass needs to be replaced. Please advice further!
Digitizer is for $15 and the whole thing is for $50. What has to be replaced and how to find out?
Please see the pictures and help me please

Get the whole thing. Replacing only digitazer is very difficult and compromises the tablet's construction.

how much cost to replace?

I did it, two times, buy the glass+lcd+digitizer combo, you can find it at ~ $40
It takes 10 minutes to disassemble the tablet and 1h+ to separate the glass from the frame, the glue is very strong and the melting point is so high that you can melt the frame when trying to separate. Even doing this you will have to scrap the glue and zillions of microscopic bit of glass embeded in the glue. It's doable of course, but be patient!

I bought the screen + digitizer from Aliexpress about $20 last month
This was the guide I followed: https://www.youtube.com/watch?v=hAlNuGrGDuU
I didn't have heat gun or other thing, I just scratched the whole screen away from frame, took me couple of hours to completely replace the screen, but works nicely. This was the first time ever I've replaced a screen.
Just make sure you have double sided adhesive tape before you start, about ~3mm or so. My replacement screen didn't include that adhesive so I had to buy it separately.

well done..patience is the key, so id be not very good at it..haha..touch wood ive never dropped any of my tablets/mobiles, hopefully the cases i always put on would cushion any blows, i bought a used nexus 7 2013 and although cosmetically its in great shape, the lcd is showing blue blobs, like ink leakage..stuck pixels maybe, but i dont think you can just do the lcd change, the whole front would need buying which is pointless as i only paid £45 in the first place.. but im so impressed with it performance wise, i got a samsung t280 in the latest sale, returned it after 3 days, the chip inside was shockingly rubbish..

broken glass

hello guys! yesterday the inevitable happened, and my phone fell off. since i can't make a photo of it, i'll put another one that looks similar.
http://cdn.gottabemobile.com/wp-con...-One-cracked-screen-HTC-Advantage-620x348.jpg
my question is, what needs to be replaced now? the whole display or only the glass? cause the whole display is a lot more expensive than the glass, and maybe i can save some money.
thanks!

Looks like just the glass. However, the glass is glued to the LCD, and I believe you need to heat it to soften the glue and pull the glass off (which can also result in breaking the LCD). Then glue the new glass to the LCD. None of which is that easy.
I tend not to be very successful with these types of repairs, and haven't personally tried it. So maybe others can speak more in terms of first-hand experience.

Send it to HTC. It cost me less for HTC to repair than it would have cost for me to buy the parts alone.
They replaced the screen, digitizer, housing, speaker covers, back cover all for £103 including 2 way shipping.
Less than 2 weeks for repair and good as new when it came back.

Should I replace touch screen digitizer alone (without LCD)?

I recently shattered the front glass on my Z1C. The display still works, but I get so many random ghost touches that it is unusable. Just wondering if anyone here has replaced the screen digitizer by itself rather than buying the digitizer + LCD screen together. Obviously it would be more difficult, however many posts about replacing both have mentioned the lower quality of the LCD image. Since my LCD still works, it would seem like a better option to use the stock one rather than a cheap knock-off. Not to mention it would be a little bit cheaper (I saw a kit which included glue, UV torch, tools, cleaner, and the digitizer for around $18 US). But on the other hand, with the added complexity comes additional risk that I will screw it up and end up worse off than just living with a duller display.
I’m still on the fence about which way to go here. Quality is subjective, so maybe I’m worrying over nothing and the new LCD would be good enough for me. I’d really appreciate your opinions.
Thanks!

Replace all.
I would suggest you to replace the LCD and digitizer completely. I broke mine in December last year. A small glass crack along the power button side made the top half of the digitizer stopped working. The LCD was fine though. I had to connect a wireless mouse to make a backup, copy some stuffs and use my old phone, while the replacement part came. Bought mine from Witrigs.com for $42 including front housing adhesive and shipping. Repairing was easy. Just heat the front part, lift it carefully. Swap the old part for the new one.
But like you I wanted to separate the glass digitizer from the LCD first. After several attempts removing the glue and the glass, the LCD had burnt spots. Maybe I applied a little too much heat in trying to remove the glass. And the broken glass left some permanent scratch marks on the LCD even after cleaning.
In all, trying to separate the LCD and glass has become very hard since last year. I've been repairing phones and tablets for years, mainly broken LCD or glass or both. From my experience, its better to change the whole part now.
Wish you good luck for the repair. Lets hope your phone lives again!!

same here. its very hard without professional stuff to change the display glass without damaging the touch under it. best way is to buy a new "complete" display module (glass, digitizer, touch) so that u only have to press the felx ribbon to ur phone. then using the glue stripes to fix it (using a hair dryer makes it easier to press it in).
Before the installation test the functionality

Hi there!
Can someone trustfully confirm, that witrigs.com is a good source for parts?
