How do I replace Digitiser/Digitizer/Touchscreen overlay?

I have had my phone open a few times...
1) To replace Vario III case with Kaiser case
2) To fix faulty keyboard, had to bend some of the aluminium on the bottom of the keyboard unit.
So I know my way around inside and haven't broken anything... yet!
Anyway, my screen is very scratched so I want a new digitizer, they're significantly cheaper than a whole LCD assembly. I got one for £5, the assembly is over £30.
I did read on some thread that the digitiser WILL perish as I separate it from the LCD screen. Is this true? If so how easy is the clean up job?
Also, the official kaiser service manual shows the LCD and Digitiser held together with tape on the outside and not double sided tape or glue like the actual assembly looks like.
Has anyone done this before? Is there a decent risk of damaging the LCD itself or to be on the save side should I just buy the whole assembly?
I have the digitiser here and ready to go as long as I can get some info from someone who has tried this.
Cheers

Sorry bump.

to be honest there will be soldering involved and u need special equipment for that ribbon

look at http://rapidshare.com/files/103168855/HTC_Kaiser_Service_Manual_jas_pik.pdf
there is detailed procedure and all the tools needed, i believe the tools are basics, and i dont think they will be expensive to have, as matter of fact, i think buying a tool box is an asset.
best luck ...

Hi!
The service manual linked to does not specifically contain information about replacing the digitizer, just how to assembly it.
Do I need a certain kind of black tape to attach it? Is that the only way it is connected to the LCD itself?
Mine is also very scratched, and I would like to replace it, preferably done by myself.
Any tips?
Cheers

a good insulation tape (anti-static prefered) will do the job

Replace Digitizer only?

My touch screen stopped working on my phone, but the screen is still visible. I'm assuming it's the digitizer. I was wondering if anybody has done or tried replacing only the digitizer. Does this work, is it better just to replace both? Any suggestions? Thanks.

Save yourself the headache
Just replace the complete screen unit (lcd + digitizer).
The digitizer is held on the screen with some super strong adhesive that is nearly impossible to get off cleanly. Also, there are three (4?) thin ribbon tabs that have to be soldered to the board on the rear of the lcd. Unless you are really confident with a soldering iron, it is extremely hard to do.
I replaced my screen unit in about a half hour. Make sure you go to the wiki and find one of the excellent disassembly guides before you start.

Thanks
Thanks, that's exactly the information i needed to know. I found the fon logix video. Is it only a t6 tool i need, or do i also need a t5. I have seen conflicting info on this? Thanks again.

I got my scren unit from ebay, and it included a torx driver and a plastic case tool. I honestly can't remember what size came in the kit, because I used my own torx set. Im pretty sure its just the one size, though.
Good luck!

You might find this information interesting.

Disregard ............

i always replace only the touch screen. okay i've done it aprox 30 times. But i never broke one.
if you decide to replace only the touchscreen, there are 2 types. thus check which on you have, and i found out that sometimes reassamble, and cleaning can help.
good luck.
torx is 5 and 6, 6 for opening the back of the phone, 5 for the screen part removal of the body and opening it. you need an opening tool!!

adhesive
is there a terrible adhesive between the screen and digitizer, as the second poster mentioned? how difficult is it to deal with?

just cut away with snapoff knives. It wil break in more pieses. (the glas that is) just be carefull, and take your time

Thanks
Thanks for all of the info, i went ahead and purchased the screen with the digitizer and tools. One thing i have noticed though is the d-pad has stopped working also, i'm using a custom rom so i'm not sure if it's just that or it's something else. i will prob re-image after i replace screen.

Well, guess I was a smarty pants and bought my stuff before consulting XDA...as such, I ONLY bought the touchscreen rather than the entire new unit. Cheaper, yes, but I had no idea about the adhesive until just now. My only question is, once I remove the old screen from the LCD with a razor blade, how do I affix the new one?
Anyone?

i would love to know this too because i have to also replace my digitizer!

I used rtv gasket maker the transparent blue one worked well.
you can find it in automotive section. Actually any silcone will work.
also can use double sided tape but needs to be very thin

I've already changing my digitizer, but it doesn't seem to work. So I've change the whole part. cost me $20 more on ebay.
my advice is to change the whole package with the lcd too.

[URGENTLY] How to replace digitizer on lcd

hi, i have my phone opened, and i dont know how to replace digitizer on my LCD screen which i take from phone
Please Urgently.. Thx. Mike
P.S. Must i open LCD scr.?

I'd advise replacing the whole screen as digitizer is glued to screen, there is guides to how to replace the screen which can be found via search one of them is very easy as just remove the four screws from behind the screen.
Good luck

If your only replacing the digitizer, which isn't easy I have done a few.
You will need to carefully remove old digitizer, I heat up the digitizer where it's glued and remove it, it will come off in pieces (glass).
then clean residue glue off lcd frame.
then glue the new digitzer.
last part is soldering the connector on the digitzer to the connector on the lcd it's not easy, it can be done with solder iron but I use a rework station makes it 100 times easier.
good luck

now it isnt urgently.. on night i closed phone.. but it is strange.. my slide effect is strange.. whn i put phone on table, so UP part (LCD,action buttons) is little moved right than DOWN part.. for ex. i think this slide after closing has opposite direction !BUT ONLY LITTLE (1mm)!
thanks for advice..
and i think this thread can could be good tread for everyone who dont know what to do with LCD. As me

I would also advise to replace the entire screen. They are easily sourced from a well known auction site and most will supply the opening tools and a screen protector.
A simple web search will find the service manual to open your pda. There are tuts for replacing the screen by removing the 4 screws behind the screen and pulling the housing apart to slide the screen out. Bewarned that if you are too forceful you will damage the mic and other parts that are still screwed to the board.
I bought two Xda stellars some time back. Both needed a lil TLC. One a scratched screen the other the housing was badly scuffed. Having repaired a few PDAs, I thought I would ask an independant store to see what they would charge (labour only as i would supply parts). He quoted £20 for each phone, have a look at the service manual see the steps to take it apart and reassemble ask yourself for the sake of £20 is it worth the aggro.
Good luck with your replacement, I hope this helps and any others who encounter similar issues.

is it possible to use a raphael lcd replacement and install it on the kaiser? thus allowing a higher dpi?

Simple answer, No !

ok, on kaiser i can use only kaiser LCD? (no vogue,no tytn 1.....)

Correct, the Kaiser motherboard is ONLY compatible with the type of screen it originally came with.

I heard the t-mobile wing digitizer would work on the tilt.
I have not try it, maybe on next one needs new digitizer.

My son has just broke the screen on his tytn2, reading through there seems to be the screen itself and the digitiser behind, if I order both of these, are they a simple fit, someone referred to soldering, I do not want to go down that route................

Just found how to video on you tube, looks fiddly, but I will give it a go.

Scratched screen

I have some kind of bad scratches on my screen, I was just wondering if I choose to replace it will I need to swap the digitizer, screen or front case?
Its not causing many problems yet, but in the sun they show up really bad and make things under the scratches kind of hard to see.

The Actual front of the screen is actually the digitizer so thats what you would have to replace, the font case dosent have a clear part its the digitizer
and believe it or not thats probably the cheapest part of all 3 to replace
and if you choose to replace it you can use this guide http://www.youtube.com/watch?v=JaAe0xWdkzI

Hello, I also have scratch on the screen, but they're not scratch "lines": in the center, where I touch most of the times, I have some kind of spots, like the screen had worn in that point because is the most touched. Anyone with this problem? What it could be?

Check if there's any protection cover on the screen. In case there's no cover and you see the touchscreen was damaged, try to replace it. Someone already have posted youtube link to tutorial. For instance, you can buy a new touchscreen on ebay (i can't post the link)

Screen and digitizer come together as one assembly. You can't replace the digitizer only.
Take a look at this video, it explains how to disassemble the phone and replace the screen:

There is no LCD on Captivate. It's AMOLED screen + digitizer as one assembly.

If you just need the lens to cover the screen here you go. Its not too expensive either. With shipping its under 10 bucks.
