Digitiser replacement - where is the difficulty - Wing, P4350 General

Can I get some input from other users please? I know cognoscenti don't like answering hardware questions on these forums so I thought that I should post this message.
There has been a good deal of discussion on this forum as well as on the Wizard & Hermes ones on digitiser replacement and how impossible it is to get the digitiser off and on again. I myself asked the question to be helpful in a thread where someone complained about a hole developing on his digitiser and of course no one bothered answering.
I have to say that I just replaced the assembly on mine and thought that I would play with the digitiser on the old one after reassembly
What is the big problem? The brown tape is a bit sticky but with a razor blade, the digitiser comes off very easily indeed. There are obvious tabs on the sides which the blade slips under and off it comes? Where is the problem?
On mine, both the digitiser and screen were smashed and I cant really conceive of a 'smashed screen' situation in which the digitiser needs replacement while the screen remains intact: If the knock was enough to smash the digitiser, surely the far more sensitive screen must be smashed as well. But not absolutely. I do actually have one unit with a large dent in the digitiser and which might benefit from a new one at ten buck a pop. More likely though is the fact that after you have replaced a few screens, you will have a few digitisers intact to try this repair. Possibly on the Wizard and Hermes as well?
No one should have much problem with buying a new digitiser and replacing it.

Cost of Screen Replacement?

Hey fellas... I think this is my first post here. Been here so long I don't even remember.
Well I have a K-JAM... I made a mistake of not buying a screen protector at the shop. It's been about 3 months now and depite very careful usage, there are quite a few scratches on the screen. I was wondering how much it would cost to replace it.
Do I have to replace the entire screen or is there some kind of sheath over it that can be replaced hence minimizing the cost?
Any inputs would be appreciated.
Thanks
Do a search on Ebay, there's a few listed there. Seems that just the touchscreen (top part, the one you probably want) is around $35, touchscreen+LCD is around $130.
I did a screen replacement on my previous phone, a SonyEricsson P800. The replacement itself was fairly easy (I replaced both touchscreen+LCD since the LCD was busted), but the touchscreen and LCD on that one were glued together forming one solid piece. Although seperate touchscreens were available for the P800 as well, there would've been no way for me to seperate it from the LCD without breaking the latter. It might be the same case for the K-Jam, forcing you to opt for the more expensive option. You'll just have to check first.
Also, have a look at the Service manual for more information, also about (dis-)assembling the K-Jam.
Goodluck!
Depending upon the depth of scratch, have you tried a repair fluid and polisher?
There is a website in the UK www.mobilefun.co.uk that sell just a solution! No pun intended. For a few pounds it might be worth a try (or dollars depending on where you buy!)
Wow... thats fantastic... I hope it works... the Repair fluid that is.
@Juicey... I cheked it up.... but like most screens, this one seems to have the touchscreen sheath glued hard to it. So i guess that's out of the question.
@BMS_Ian... has anybody around here actually had any luck with these repair fluids?

brocken screen

right i dropped my brand new exec which id claimed on insurance doh! now i have a blurred screen, the touch part still works an i can still make out whats on the screen but there is a crack in the corner & the whole screen is almost white, do i need to replace the whole lcd or just the touch screen top part? iv been looking on ebay and have seen just the touch part going for about £12 whereas the whole lcd section is roughly £100
Seems like you have a broken lcd, even if some touchscreen are mounted on top of the lcd screen on a separate fine glass sheet, since you say that the digitizer (touchscreen) still works, the crack will almost surely be in the LCD screen's own glass, so no hope for you, go for the entire screen and change it if you can of have done by a qualified technician.
Sorry for the bad news and make a very deep research at Ebay, you might find it for less, might be buying another universal whose defect is not the display, it's not an uncommon thing to see defective PDAs for sale there.
bye

Fixed problem!
OH NO!! what HAVE U done!!!
I know...The horror...I haven't re-assembled to see if still working...HA!
I disassembled because of a cracked digitizer.
looks like a fur or "plastic" carpet, hope you don't end up with ESD related problems
ESD as in ElectroStatic Discharge ^^
Phone still works just fine.
If anybody knows how to un-solder the digitizer away from the lcd, help would be appreciated!
New images added.
Next up:
digitizer/lcd separation
any updates?
Have you managed to fix it yet?
We all want you to succeed so we can operate on our own cracked ones! Maybe you need the "unglue" chemical - you know, like superglue has an antiglue for reversing it's stickiness. If you could find out what glue bonded it, then a specialist adhesive supplier probably knows how to reverse it.
I'm sure you'll like this (if it isn't posted here before...)

Well if they're cemented (hopefully with some hyper-glue), thats a GOOD thing. Then this will be (hopefully) my first device with NO dust under the glass.
Don't you people have insurances on your devices? Talk to the ensurance company and you will get a new device for a small excess - that is, if it's beyond repair

its not ... I have dust under the displayglass.
Floatheavy, and everyone else.
I'm currently on my second HD2, first suffered a hairline crack on the digitizer and it went COMPLETELY unresponsive. After getting the second, I had nothing to loose and disassembled the first. I got everthing apart up to the LCM, this module has everything (the glass digitizer, the LCD and the backlight) all cemented together. As I took the phone apart, priodically I would test that it still worked - everything except the digitizer. When I tried to separate the digitizer from the LCD and baclight I ended up tearing the layers of the LCD apart, now one layer is still glued to the digitizer and one is still glued to the backlight. I have yet to see how this can safely come apart and untill I can buy the LCD the phone is totaly screwed. I think one has to purchase an entire LCM and not just the digitizer.
For those that want to try separating the digitizer - BEWARE, noone seems to have found the secret yet! If I manage to discover something new I'll post.
Yeah. I tried the heat method to separate the digi from the LCD...
No luck
It seems it is more than the simple adhesive broken down by heat.
To get the bezel away from the LCM you can use heat to make easier, but to get the digitizer away from the LCD itself remains a mystery to me.
Anybody get any other results?
OKAY..
Pics updated again...
I was able to get the digitizer apart from the LCD, using a razor.
for separate lcd and digitizer
For separate lcd and digitizer, I used nylo fisher string... and it work good... just right my problem is how to past new one ? neopren glue ?
Honestly, I plan on just adding a dot of super glue to each corner.
I believe most phone adhesives are a sylicon based glue.
It`s almost impossible to un-solder the digitizer away from the lcd, i have succeeded a few times whit hot air and very sharp cutter, but still broke 2 screens from 5...it has to be a solution for this...anyway 3 phones from 5 its not the best rate...

Cracked screen - screen protector

Hi all, I cracked the screen on my HD2 a few days ago and have been eagerly reading the reports of how to replace the digitiser, etc. I'm working up the courage (and getting the tools) to do it, but in the meantime the digitiser and screen are perfectly functional, if a little bit unsightly. I thought I'd get hold of a screen protector in the meantime so I don't end up with bits of glass in my fngers, etc. Any recommendations of a form fitting protector (or form fitting case) that would fit the bill? Ideally it would cover the bezel around the buttons too, because one corner of it is quite chipped. The pics on ebay are kind of hard to tell from. Any advice much appreciated!
I might be too late as you mentioned that you already getting the tools to fix it yourself. There are specialty repair shops that fix screens, I heard they are not too expensive. I don't know the exact price, but someone with a broken nexus one got his phone fixed this way. Do you mind telling how you cracked your screen, was it your negligence or is it too fragile?
I'm not looking for info about how to repair - I've read those threads. I'm interested in the best temporary fix for the meantime.
The cracked screen is largely due to negligence... dropped it outside. Woulda been nice if the phone was a little more sturdy, but can't expect much better. And thank God it still works just fine as far as I can tell. Gonna be more careful now...

Broken Screen

Dear all,
anybody already experienced a broken touch screen?
My Leo fell from 50cm to the ground (tiles), just on the edge. The sound it hit the ground already let me knew - bad suprise...
If you have already some experiences with broken screens: Is there a way to repair it? Is it be affordable?
The device itself seems to work as usual. Even in the upper right corner, the sensitivity seems fair. But I fear a breaking screen as already some glassy bits drissel out...
Thx for tipps
TC
i belive its called digitizer on most touch screens.
not sure if HD2 has different technology.
but the LCD screen is separate from the touchscreen part(thats what you broke)
search ebay for HTC HD2 digitizer
heres the ebay link i bought a camera LCD display from them few times

Hey dude,
Check out this thread
forum.xda-developers.com/showthread.php?t=613954&page=20
I broke my glass on my screen and ordered a new digitizer, stripped it apart, broke the LCD in the process (a common occurrence as the glass/LCD glue is STRONG), ordered a new LCD, repaired and it works.. didn't quite go back together as it started (slight gap in case, buttons don't come through as much as they used to). Now have the problem of the 'bubble wrap' showing on the screen in a few places.
In short, yes it can be done but if you want it doing right get a professional to do it..
Any one else with there own experiences?
heat it up so the glue is soft and comes off easier, between the screen and digitizer.
if you have sun leave it in the sun to get it up to good temperature.
safest way since it will not get too hot where it melts.
