How to replace the digitiser - What type of glue should I use ?

I dropped my phone and need to replace the housing. It looks like the digitiser cannot be easily removed from the housing, so I bought one of these as well. Now all I have to do is move the phone from the old housing to the new and install the digitiser in the new housing.
Now it looks like the digitiser may have been glued in place. What type of glue should I use ?

More liked taped in...... I'm sure that lots of people will respond with.. Double sided 3M tape.... but if there's anything better/stronger than that on the market use it. Make sure it''s really thin tape to. I'm gonna be replacing my housing in the next month or so aswell. Goodluck.

As I also will replace mine digitizer, the newton rings are bugging me, it will be appreciable if you can share your experiences of the replacement process.
thanks in advance and god luck

Hey on more thing. I took apart my phone last night and put it back just so I know my way around when parts come in.
If your Digitizer does not work try loosening the top srews 1/4 turn. You have them on too tight.

I wasn't replacing mine so I didn't have to remove the existing one. All I had to do was attach a new digitiser to a new housing.
I was told that double sided tape was the best, so I tried that.
I used the instruction from http://www.pdacenter.ru/razborka/htc-touch-diamond2 which was easy enough.
You need to ensure you remove the micro SD card first.
Also I forgot to move the LED diffuser from the top, so I need to repeat the process at some stage.
The housing I bought had a number of issues
* The two screw point near the bottom of the housing didn't have the metal inserts with the screw threads
* There was no seal between the metal housing and the LCD screen. This could let dust in.
That's about it for a brain dump.

Hi there,
I was also tired from that oil stai and ordered a new digitizer from these guys:
http://xxx.sw-box.com/htc-touch-diamond-2-t5353-digitizer-touch-panel-screen.html
Surely it arrived in 6 days, to my horror it was a generic display,
Had some trouble removing the old one, ended up breaking it
The generic did not fit snugly, I had to sand down the edges to make them round, also had some trouble with the four buttons below getting stuck when pressing down, (shaved of some extra plastic). anyway used double sided scotch film to get the digitizer back in place.
apart from a few difficulties, it works like a charm.
Should have ordered an OEM but what's done is done
Next time I'll do the cover and get a new digitizer
Regards

I would of thought double sided tape too thick to use to stick the digitizer on.
I was thinking of using a very thin sliver of clear silicone.
Anybody tried this or have any other suggestions?
Thanks

I used a very thin layer of supergleu and it worked great!!

My digitizer came pre-glued. I didn't need any sort of glue.
http://forum.xda-developers.com/showthread.php?t=715724

Silicone is OK
I used a very thin layer of black silicone and placed a book on top of the digitizer to keep it pressed flat into the case as it dried overnight. No problems since then...
The missing metal screw inserts can simply be pulled out of the old housing ; insert screw halfway and gently pull with plyers. Carefully hammer into the new casing; insert screw 3/4, put something thin and metal on top to prevent the screwhead from getting damaged and carefully hammer into the void. Make sure it goes in straight.

I've got exactly the same issue with my new housing, no bottom screw threads and no foam for the lcd to rest on. Am trying to pull the threads out with pliers but I think the old case is going to break first or strip the threads.
This is isn't an easy job

have finally finished this epic!!!!
had to break the bottom screw threads out of the old front housing and took a good while hammering them into the new housing so I didn't break it.
used a small sliver of clear silicone to glue the digitizer in which seems to work well so far.
Have not put any foam or anything for the LCD to rest on, time will tell what effect this has.

I need to change mine as well. Where can i buy a good quality digitizer and case preferably pre-glued?
I found a few on ebay but i am not sure of the quality.
Thanks

Today i searched also for shops which have digitizers and housings. I have found 2 shops, but one of them is a german shop (http://www.mobileok.de) which does not deliver outside of germany and austria. But the other one does: http://www.sw-box.com/

what kind of glue? it's the third time that i'm re-gluing it, but dust keeps coming inside....

I guess, it is not possible to hermetical seal the housing. I had dust in my original housing too. There are a lot of small gaps everywhere not only between digitizer and frame. But it would be easy to disassemble the device from time to time, remove the dust and reassemble it again. Save your energy in the effort to make your device dust proof.

Repair HD2, now trouble assembling?

I recently tried repairing a friends HD2, because he had a smashed screen.
I bought the new screen and some 2mm double sided tape. Took the phone apart, and managed to see the lcd was damaged also. Bought one of those then taped the new screen and lcd together using the tape.
The inner chassis had all the old tape on it still, so I bought a new inner chassis. Waited for it, then stuck the new lcd / digitizer to it. The button end didnt seem to stick down that well - even with the new chassis, with the buttons wanting to drop out, and them not sitting out of the screen like they should.
I thought it must be due to the phone only partially assembled, so went ahead and installed the rest of the phone.
Now its together the button end of the phone wont sit in the shell properly and the buttons seem to be lower than they should...
How am i supposed to get this inner chassis to stick properly, and are there any tips or vids to show how its supposed to sit?
thanks.

maybe this video can help you with assembling your phone.
Search on youtube for t8Q7mXdcJ54.

Ive watched that video numerous times, and its a little misleading as to how much is required. Extra tape in places that had to be cut and removed, labels not sticking back down like they do in the video etc.
Im after information as to how people stuck the lcd/digitizer to the inner chassis. I used a new inner chassis with tape pre applied, and it still didnt seem to stick the two things together enough. When you stick the chassis (with lcd/digitizer) into the outer case, it doesnt sit into the case enough, and the buttons are not sitting right.

If u have purchased lcd with digitizer,u could look for flat cable that connects from lcd to mbo,maybe u need to form it.buttons have points to allign,but u need to center both sides in micrometer to function normal.lcd/digitizer frame must have black tape on edges.

I have the same problem like foney!
See this:
argh, i can't post my photos! how to do it now, i don't have 8 posts yet!
I've used "3M 300LSE" as a profesional doublesided tape i thought and also put a 2mm stripe below the keyboard, but the display is not really fixed onto the chassi around the keyboard and the keys also can't be used really, because they are maybe not correct centered onto the keyboard circuit board. i've been using the assembly video from htc, but there it's not mentionend very well, how to do it right.

Hmm,last thing i can think is that lcd/digitizer is not properly glued/taped.Did u put pressure for few hours on lcd/digitizer and middle frame?

it is taped on around the lcd using 2mm 3M double sided tape. The chassis i bought new, with tape included. When you stick the lcd/digi to the chassis, it appears that the button end, as l0rdius mentioned, isnt stuck down enough.
The video has the guy "magically" sticking it all together and all going together as it should, but doesnt show any real detail, like showing how things go together to fit properly.
edit/ pulled the phone apart again, and its definitely a case of the tape on the chassis near the buttons not sticking correctly. Ive wrapped it in rubber bands, and used some wooden clothes pegs to try to secure the two better. If it doesnt stick, then I may have to use something stronger than tape, like Tarzans Grip

I've found another thread, in which "profahmad" posted some hints:
http://forum.xda-developers.com/showthread.php?t=640328&page=8
Today i've ordered some more 3M 300LSE and want to take a new try on weekend with these hints. Hope i get the display better glued to the chassis and the buttons correctly justified.
Whats about the sticker under the battery. do you guys have problems reassembling it again and again? Or how do you handle it?

Im using glue like in the link if applying pressure for a day or two doesnt work.
I applied a little double sided tape under it, then when i left the phone for a few days with the battery in it seemed to stick down fairly well. Not like factory new, but good enough.

Replacing Touch Digitizer fix NonResponsive Screen?

Hey everyone my HTC HD2 got the Non-Responsive screen problem a week ago, & did a lot of research and found out that it was most likely a hardware problem with a cable..... So a lot of people would tell the people with the problem that the "Touch Screen Digitizer" is dead (like the cable), or it needs to be cleaned... pretty well go out and buy a new one... BUT I have never found evidence that someone has done this and it has successfully "cured" their HTC HD2 Non-Responsive touch screen problem...
So I was looking for anyone on the forums that could confirm this is a solution or give me any tips on what I should do.... AND no I don't have enough money to get a new phone, nor do I live in the USA so I can't send it in to fix it...
This is what I was going to buy for it:
http://www.ebay.ca/itm/NEW-OEM-HTC-...781?pt=LH_DefaultDomain_0&hash=item519a3d2e45
Thanks for taking the time to read my Thread, its much appreciated!! I hope I can find a fix!!
PS: If anyone wanted to know what it looks like out of curiosity I posted 3 pictures with RED circle HIGHLIGHTING the problem when I try to touch something....

My digitizer has been a bit dodgy for the past few months. It's ironic that when I finally found out what the issue was and called HTC, my factory warranty had ended exactly 4 days prior to the call.
Fast forward 3 months and my phone has now been unresponsive for 3 hours despite my prying and tweaking various hard parts.
I disassembled the phone down to the main board just to see how hard the install is, but it's a bit intimidating once it's time to start pulling all the film and ribbons. A bit too tight and small parts for my liking.
Time to hit CL to see if I can find a cheap replacement.
Good luck with your repairs. I may be following in your footsteps if I can not find a good deal.

Yeah I will see how well it goes... if anyone has useful info, i will be more than grad to hear it
Thanks

Many people attempt to replace a digitizer, but I simply don't recommend it, we see enough of do-it-yourselvers who created problems in addition to the original ones.
What I do recommend, however, and I stated it on many threads already, is to get an LCD+DIGITIZER assembly. Simply because it is easier to fit. Not saying the overall fitting is easy, always depends on your overall skill, so ensure that you are familiar with the procedure BEFORE you begin. But you will save yourself a lot of trouble by getting the whole thing, as opposed to the digitizer only for the sake of a few bucks.
However, if anyone still feels intimidated by the whole thing, I am on the lookout for working main board. Advertised a few times in the marketplace with limited success. So if anyone smashed their baby and will be looking to replace, rather than repair - drop me a PM. I am in NZ. Will pay by Paypal.

Mm i've replaced my HD2 screen just last night. Trust me it's among the most complex phones around.
Unless you've done a few phones before i wouldn't advice you DIY. Otherwise you can look carefully at the Leo Ds. and Leo As. guides on youtube. those helped me!
Mm i killed my LCD in the process of removing the digitizer as it's stupidly glued on to each other and the LCD glass is thin as hell.
Get the set, it'll save you your time
Mm i got mine of ebay, from the seller goodgoodsecho. It works perfectly well for me!
All the best!

Thanks I will check it out, hopefully it won't be to hard and I hope I can repair it!! oh and could you post a link of the youtube & manual you used to replace your screen?? Thanks
Oh would anyone suggest then just calling HTC and sending it to them to repair?? or does that cost to much??
Thanks everyone for the help

One word of advice I have, is just remove the LCD/digitizer module assembly and don't remove anything else.
I have no idea why these videos and manuals have you pulling circuit boards, flex cables, and disconnecting stuff just to remove the LCD module. All you really have to do after removing the rear housing is to cut through the double-sided tape holding the LCD module to the main frame, being careful to know where the flex is and not to go too deep there. I used a credit card for that, but anything similarly flat and thin should do.

Yep, there is absolutely no reason to take off everything like some people seem to think is necessary.
The way I'm talking about requires removing LCD+digitizer. In fact, I think you'll always have to remove both because the connector for the digitizer is under the LCD. Anyway, the way I did it, I went from removing the the phone insides from the rear housing straight to separating the LCD+digitizer assembly from the frame. No removal of any boards or flex cables. The only cable to be disconnected is the LCD+digitizer assembly one. Getting it disconnected and reconnected does require unplugging the front button flex and removing the screws for the bottom logic board to loosen it, but that's all.

Well, it's not that simple because simply getting the HD2 insides out of the rear housing is difficult if you've never done it before. I believe the screwdriver you need is a Torx T-5. Once you get the screws out, you will need a plastic opening tool to go between the digitizer and rear housing frame. They look like this:
http://www.ifixit.com/Tools/Plastic-Opening-Tools/IF145-000
I found it comes out much easier if I use the tool to make a gap along the top edge and then slide the entire end of a scrap credit card into that gap, then that makes the whole assembly easier to pry out along the sides with the tool. I know on one of the vids, the guy takes forever doing this part and I can understand why, but once I figured out sliding a credit card into the top gap as far as it would go, I was able to get it apart much easier.
I can't answer whether the phone will work properly, because I just ordered the new digitizer over the weekend and haven't put it back together. I did remove the LCD+digitizer assembly and then re-connected it and put it back, then powered on the phone just to make sure pulling the LCD didn't hurt it - it didn't, everything worked as well as it did before. I did manage to crack the digitizer more when I tried to get the insides out of the rear housing before I figured out the credit card trick, so fortunately I was not trying to save my digitizer as it was already cracked. If you are just wanting to try to clean or fiddle with the connection, then you're going to have to be a LOT more careful than I was because it was all too easy to crack the digitizer!
I'm guessing yours probably needs replacement though. I sent my HTC Surround in for a funny acting digitizer, and the digitizer was replaced.
Oh, and if I would have bought an LCD+digitizer pre-assembled unit, that would have been super easy to replace. However, I opted to save $50+ by buying just the digitizer. Not too sure how I'm going to prevent dust getting in it, and I've read thickness of the adhesive is critical. I may regret it later!

Nope, I didn't disconnect anything except the circled connector on the far right of your picture. You will need to do that to remove the LCD flex cable from the logic board.
I've attached a pic of the LCD module loosened from the frame. What you do is use something thin and flat to separate the adhesive tape holding the LCD to the frame. You will need to lift some of that black fabric tape on the edge to see where the LCD module meets the frame. Near the top, you will probably have to slide your separating tool all the way through to separate the tape (I used a scrap credit card). Avoid the area where the LCD flex cable is, because you could damage it! It's on the lower right of the LCD if you are looking from the front. When the LCD is loose, lift up from left to right (when LCD is facing you), pretending that there is a hinge on the right side. This is because you don't want to put any force on the LCD flex.
Once you've got your phone looking like my picture, you can remove the "captain" (orange tape), unlatch the LCD flex from the top, remove the button flex from its connector, then loosen the bottom logic board from the frame just enough to pull the flex out of the connector.
I hope that makes sense! It probably helps to know that a very strong double-sided sticky tape is all that holds the LCD+digitizer assembly to the frame, and there is only one flex cable connecting LCD+digitizer assembly to the rest of the phone.

You could try heating; I didn't, but maybe it will come apart easier if you do. In the HTC factory service video, they mentioned putting the whole phone into the oven to loosen the tape. I didn't know if it would be a good idea to do that complete with all the circuit boards or not.
No, without heat, the tape is definitely ruined and I will need to replace it. I was planning to use some leftover tape I have from fixing iPhone digitizers so I didn't even attempt to salvage the existing tape. Not sure if it's even possible to salvage that tape considering you need to stick some kind of tool in there to separate it.

Broke the front glass of my G2 :( -- FIXED! :)

Everything works fine (except for the camera focus, which I can live with since everything is in focus always as it is because it shoots at like f/8). What's weird is that it has survived so many other falls onto concrete, and this just happens now.
I really need to replace the glass as soon as possible. It looks pretty unprofessional cracked like this.. I am out of warranty (bought the phone in September 2010 from T-Mobile), and T-Mobile no longer has any G2s .
I've looked through a few people who have mentioned replacing their front glass, and would like to do so myself. Anyone have advice regarding how I could do this?

http://www.youtube.com/watch?v=u-dR8CHEGjY

less than $20 for new digitizer, takes 30min -- leave yourself an hour if your new to this

Sweet thanks! Looking forward to getting this done. Will keep this thread updated.

Ordered it from the website. Hopefully will get it soon.

I highly advise AGAINST super glue for securing the digitizer.

Okay - what would you recommend instead?

the glue that is on your phone now will sufice. when heat it up with hair dryer (be carefull if you use a heat gun) most of it will stay along the frame of your phone. just keep it warm and quickly put new digitizer back. have done it twice now with g2s and countless times with g1s and no dust has ever seeped in.
but with g1s i often replaced the casing as well. here i would use 3m double sided tape that worked very well. if you are also replacing the case or for some reason dont feel the glue is enough use this

I recommend 2mm 3M adhesive tape. I have used it for the 3 g2s I own and it holds darn well. Its less then 5 bucks on amazon and you will have quite a bit of it. Dont use glue. I always take off that old black tape.

the glue that is on your phone now will sufice. when heat it up with hair dryer (be carefull if you use a heat gun) most of it will stay along the frame of your phone. just keep it warm and quickly put new digitizer back. have done it twice now with g2s and countless times with g1s and no dust has ever seeped in.
but with g1s i often replaced the casing as well. here i would use 3m double sided tape that worked very well. if you are also replacing the case or for some reason dont feel the glue is enough use this

The tape doesn't make the digitizer bulge away from the surface at all? I feel like it would. I'll give that link a buy though, just in case.

the tape he and i is refuring to is thinner than paper, i have not needed it for a g2 before but only have done 2 digitizers on these so i cant say its never necessary unless you are replacing the case as well, but its cheap to have around and may be needed

No if you stack it right I had to stack three pieces of that tape to flush it. It does not move around if you tape in the right spots. Its very thin and almost invisible.

That is weird... I did the SAME thing last week lol! I busted it on the concrete too and everything. It scratched up the bezel pretty bad too. I had insurance so I ended up getting the MT4GS (aka HTC Doubleshot). I love how speedy it is but I REALLY miss the development here and the GREAT community here in the Desire Z/G2 sub forum As far as repairing/replacing the screen (the digitizer specifically), everyone here gave great advice. I used to repair phones for a number of years and we always used a sealant very similar to double sided tape that y'all were mentioning. It basically was foaming glue that acted similar to silicon or something. I agree that about not using super glue. Bad idea. Also be careful with the ribbon wires and watch a few videos prior to disassembly. There were a few tear down threads here I'd keep handy while repairing. Good luck to ya!

Make sure you are VERY careful when removing the lcd its very fragile. I reaced my digitizer easy and was careful and lcd got mrssed up ie no pic. Ordered a new lcd and it had not brightness control always dim waiting for new replacement now. Side note once new screen comes in I will be selling this phone if anyone is interested i have 3 of them only need 2

Son of gun. The last three screws I need to remove do NOT fit with the philips head screwdriver that was recommended. Now I get to scramble around with my phone in pieces trying to find a smaller philips head screwdriver. Awesome.
They are philips head, not torque screws. I checked and triple checked.

Anyone have any idea what to do here? I can't find smaller screwdrivers anywhere. Home depot has got nada.

Go out and buy a precision screwdriver set or maybe a eye glasses repair kit. Only the first 3 screws are torx T5. Also there is 7 of them tiny ones not 3. There is 3 on either side and one more under keyboard backstop

No it's the three screws across the back at this time (http://www.youtube.com/watch?feature=player_detailpage&v=u-dR8CHEGjY#t=251s).
They are smaller than all the others and I still cannot get them out. I cannot find an eye glasses repair kit or precision screwdriver set small enough.

http://www.repairsuniverse.com sent me the screwdrivers for the Inspire 4G. Pretty sure the digitizer is for the G2 but I'll have to check the screen sizes to make sure.
Update. Fry's elecronics had a repair kit for smartphones that fit the screws. Still working on it.

if you keep watching the video you will see that when he removes the sticky keyboard backstop there are three more identical size screws mirrored from the ones you are talking about right on edge of phone, and then when you remove that piece after you remove the screws there wiil be one more (this makes number 7 ) screw of the same size tiny. Also i dont think it is metioned in the video but when you go to remove the keyboard backstop (the shiny piece under the sticky strip ) use your safe pry tool to unlock the tabs from the edge and then you must slide the piece towards the center of the phone it does not just pry off there are tiny tabs holding one side down opposite of the screws ( edge of phone ) And as far as the screwdriver for eye glasses repair, is it you cant find one or it just does not work? You should be able to find one at any walgreens or equivalent drug store or pharmacy. You could also try a hobby shop they might have something that will work. I personally use quite a big screwdriver to disassemble you just need to make sure it has a sharp point at the tip of the star ( mine is a phillips number 00 ) Believe me once you get it apart once you will be that was so easy.

[Q] is that possible?a guy replaces full display (lcd+digitizer) in just 3.5 minutes!

just found a very easy way to replace the whole display in just 3 minutes by accessing it from the front side..
i am not yet allowed to post the link, but if you google this
IMPEXTROM CAMBIAR TROCAR DISPLAY HTC HD2
you will see the 3 minutes video
seems possible as there are 19 positive and just one negative vote on this video..
(my display was broken, but have worked for a year or so.
now it is frozen/ unresponsive and i have purchased a full display.)
but it seems too easy to be true ...
any hints?
thanx &cheers

That been set up for the video as you can see it been off before & the chassis the lcd is bonded to is clean of all bonding tape :-/
Also original has signal interference tape runing down sides across all 3 layers.
also if you heat the front first thing to seperate is the digi from LCD as the lcd to mid chassis is a strong bond.
Best way is popping them out of rear cover, fitting a pre built lcd/digitizer is not hard, just use quality adhesive to hold lcd to centre chassis & buy pre cut black foam tape for the top & bottom digi glass edges or rebuild is next to pointless without this done well.
I've done a good 30 odd HD2 screen & mainboards & no way I could do it to my standard via that video.

Hi Mister B - thanks a lot for your advice, i believe you are right!
but as i have never attempted to disassemble a mobile phone, is there a video tutorial how to do that properly for an absolute beginner?
as I need my phone functioning tomorrow, i'm considering to try it in the morning.

Not sure if Mister B will reply in time, there is a good thread here http://forum.xda-developers.com/showthread.php?t=1566179 with a video in post 2 else google hd2 disassembly youtube perhaps

Hi Robbie P,
Thanks a lot for the link!
Now it seems I will have to postpone this operation for a day or so, until i learn:
1) What time I would need (seems about 2h for a beginner)
2) What money I would need - as I have to buy these tools- what would be a price... i guess 10-15 euros?
(BTW Finally I guess that people who published aforementioned 3.5-minutes tutorial did so not to help us, but to make us damage our smartphones, so their services would then earn more, repairing it?
As I see no other explanation...Now found another such a scam video -
just google " HTC HD2 repair, disassembly manual ")
Cheers

Have a good read of link put up by robbie p
I done a few posts in it that worth looking at as you don't need remove the flexboard & volume button & antenna cables which saves a lot of possible accidents & hassle.
Most important thing is extreme care, volume button is damaged easily if pry of back badly or with screwdriver. antenna tabs are snapped off mainboard with poor handling while separating the layers.
It easy to do but first one is never perfect unless you really pay attention.
You don't need much tools, a basic kit from ebay for about 4euros will cover you along with things you probably got already such as hairdryer & razorblades etc.
Just buy good padded tapes to fit top & bottom of digitizer & strong tape to bond lcd to centre chassis

Hi Mister B!
Thanks a lot for you precious advise.
Will try to do it myself, not in a hurry, as soon as I get 3 hours spare time - hoping it would be enough.
Then I will need to install some good Android instead of the original WM6.5- but that is for another topic
My Qs:
You don't need much tools, a basic kit from ebay for about 4euros will cover you
this is what I got with my display from Ebay: Is it enough?
1 pry tool ,1T5 screwdriver and 1 T6 screwdriver.
Just buy good padded tapes to fit top & bottom of digitizer
I also got this one from Ebay: is it good? if you paste the title below into ebay.co.uk it you will see more details:
2mm Double Sided Layer Adhesive Sticky Tape Sticker for Mobile Phone Glue LCD
& strong tape to bond lcd to centre chassis
Which width, and should it also be double-sided?
Cheers

For tape you want this >

I assume you have lcd & digitizer pre-built new !?
You would be better off with couple more decent pry tools, the green ones tend be better than the blue plastic stuff.
I use 2 pry tools on top of HD2 either side of speaker grill as makes back housing removal a few second job & leaves not one mark if done right.
Only other thing you may need is tweezers & cleaning buds for old glue.
top digitizer tape need be right or blocks sensor hole or looks shabby.
Don't force the old lcd off centre chassis as if gets bent then never fit back right, warming it up with hairdryer helps ease it off.
I always have a spare button board on hand too as makes it easy bench test the lcd/digitizer hook to mainboard side by side with battery held on mainboard pins & spare button board used to power on, also good as likely find old board breaks if gone brittle.

tools I've got
Hi Mister B!
Thanks so much for your suggestions!
Yes, I've got the full display, and only the tools as on the photo.
My few Qs:
Only other thing you may need is tweezers & cleaning buds for old glue.
Could not find plastic tweezers, only metal ones... But those cotton sticks for ears i have
I could order the LCD tape, though it seems a long wait (7-10 days) for express delivery up here, so is there an alternative?
Thanks for a link to the button board! As I guess mine is damaged, for during last few months I had to press hard on the power button to get the phone responsive again. Then even this trick stopped working.
But also due to the longer waiting to get in from China - is there a way to test and learn if i need to replace it , before starting digging into my HD2?
Cheers

I would get the lcd digi top/bottom tape kit as what you got in big roll will be no good.
all else is good.
button board is handy as ribbons go brittle so can break plus you can use it to power up the device in a pre build test with lcd/digi & mainboard laid flat side by side & new ribbon plugged in to mainboard to power on. Most stuff makes it to uk pretty quickly, quicker order - quicker get it

Well, i will then order both items today, in hope it won't take too long to deliver up here (Belgrade, Serbia).
A video tutorial with all the tricks you have suggested would be the easiest way to follow, but it seems there's no such a video - yet.
Certainly, I'am either not sure whether will be able to film my own attempt.
Mister B - thanks so much! Following your suggestions, and the topic mentioned by Robbie P - I will likely manage to do the job properly!
Cheers

If have any question during rebuild post them here & I will respond as soon as see it.
Good luck ...

Thanks!
