[Q] how do I troubleshoot/repair NC LCD+digitizers? - Nook Color Q&A, Help & Troubleshooting

the other day i bought on ebay what I thought was a good bargain - nook color front panels for $6 each
nook color LCD + digitizer assemblies
so i bought 3 of these panels with the understanding that they didn't work because the digitizer was broken,
Now, here's my 2 scenarios that I have in mind as my proposed attempt to get these screens working again so they could be transplanted into any future nook color tablets that I might buy on ebay with cracked screens -
Scenario # 1:
since the glass is intact, I was researching ways to separate the non-working digitizer from the LCD part of these screens, and once source said to bake the assembly in a kitchen oven, bake at 280 °C and use a very thin pry tool to separate the LCD part of the assembly from the digitizer part, this told me the lcd is glued to the digitizer, and since i have a 12 temperature settings digital heat gun (Wagner brand from Home Depot), it's 1500 watts/5100 BTU's, and can go from temp setting of 250 °F to 1350 °F, and from my bit of googling, I also found that the LCD's are more pricey than replacement digitizers, but again, I'm not sure if I got a good bargain.
my tablet tool kit
My 12 setting, 12 amp heat gun
and my googling on this topic took me here
where my googling this topic led me
that said, what do you guys think of my purchase/research, etc?
now I have questions:
can I use my new heat gun instead of the kitchen oven to melt the glue holding the broken digitizers to the inside of these NC front panels I bought?
do you guys think I got a good bargain (3 LCD screens once LCD's are separated from the digitizers)?
since I did conversion of heating temp of 280 °C to x°F, I got a temp of 536 °F, I'd have to have my heat gun set to 536 °F, but the gun has as its setting ranges: is lowest temp 250 °F, high 350 °F, the next low/high temp settings are low 450 °F, high 550 °F, and the rest of the settings (low/high) go even higher with the next low temp setting as 650 °F and up, so how am I supposed to do this when I use this gun of these nook color LCD assemblies to melt the glue - what temp should I put it on?
how long should I wave the gun's heat at the LCD assembly?
what sort of motion should I wave the gun in - circular motion or left/right, or top/bottom?
do I need a special timer - (I have a pocket watch with a second sweep hand)?
I also have ipod/ipad pry tools (plastic spudger, guitar pick like tools, one smaller, one larger, a metal pry tool with narrow rounded blade at one end and pointy blade at opposite end) - which tool should I use to separate the glass LCD from the digitizer after using the heat gun to loosen the adhesive?
do you guys think this heat gun was a good investment (I also plan to use it to reflow the ball grid arrays of laptop video chips in future)?
Scenario # 2:
now I'm thinking of leaving these 3 LCD+digi's assembled and forgoing wanting to separate the digi's from the LCD's of these screens, and am now thinking of troubleshooting the non-working digitizers in these LCD assemblies and possibly getting these digitizers to work again.
Has anyone ever had this problem before and successfully repaired their non-working digitizers?
if, so could you show me how to troubleshoot these digi's and possibly get 'em working again?
since I asked this question in 2 forums and still received no replies, I did what I think may be a big mistake: I asked the seller these troubleshooter questions but I think I'm going to regret it later?
this is what I asked the seller:
regarding separating the glass from the digitizers in these screens, I did a bit of googling and an article somewhere said yes it can be done but it's very difficult and the chances of success is very slim, so now I'm thinking to myself, that instead of trying to separate the LCD and the digitizers, why not try to find out why these digitizers in these screens do not work, so may I please ask a few questions pertaining to why these digitizers don't work so that I might try to troubleshoot them and get their digitizers working again -
--when did you notice that these screens stopped responding to touch?
--what happened to the screens (anything odd/unusual) just before you noticed that they no longer responded to touch?
--what did you do (if anything) to try to make them respond to touch after they stopped responding to touch?
could you answer my questions, if you can, since I'm a student computer tech.
the LCD/digi's i bought on ebay are still in box, i haven't even touched them, let alone opened the box.
On the other hand, what if I went with Scenario # 2 and forgo Scenario # 1?
thanks in advance.

Replacement touch screen

I have couple of scratches on my touch pro screen.when the device is on the scratches are like rainbow colors really visible.If I change the touch screen (not the whole lcd screen) that will fix my problem right? Did any1 do this?
ummm i think when u meant by "rainbow colors" then ure gonna have to replace the WHOLE LCD screen, cuz more than likely its from the LCD screen, and i dont think the touch screen and LCD screen are 2 parts...i think theyre just one...not sure, but try to look on ebay OR idk if u have warranty on it u can probably call in HTC about it...
This is what I think will fix the scratches

mikechannon.net is a good place to start. But if you are looking to replace the digitizer only, you won't find it there. It's a bad move anyway. I tried that, cracked my lcd and end-up buying the whole lcd like this.
All I can tell you are my mistakes.... lol....
- never peel of the digitizer. it will ruin it.
- never try to remove the lcd with cutter blade. this is how i cracked it (stupid me and still regret it)
- between the lcd and the digitizer there is a thick, clear double tape like glue. i came across some information about this somewhere (forget where...). one said you should heat the glue first (don't know how to apply this without affecting the lcd) . other one said have to use dental floss.
So, there you go.
HTC Touch Pro- LCD & Digitizer replacement instuctions
Hi everyone. I have SCOURGED the internet looking for some kind of decent instructions to replace the LCD & Digitizer screen on my HTC Touch Pro (Sprint) phone with the new set I purchased from Hong Kong. Mike Shannon's site does NOT give directions for this specific area.
I have seen you all talking about needing to do the same thing and wonder if anyone has done it? And do you have any directions to help me?
I've had this part for a month now, and can't find any directions to do it! My dog chewed it, and the touch works, but the screen is half black now. I read it is easier/less risky to replace both lcd and digitizer, which I went ahead and purchased them both with the tools, now I just need to find something decent (instructions) to have help replacing it.
thanks to anyone who can step up to help me, I'm frustrated beyond all comprehension, and now feel I may as well ditch the phone if I can't find a way to replace it. Or maybe you know someone I could send it off to? Everyone wants to charge a couple hundred bucks sending it in to them!
to the appling heat ...u can try putting it in a ziploc bag and boiling it ...and for the instructions this is the best i can do for u http://store.payloadz.com/str-asp-i...nance_Manual_eBooks_Technical-end-detail.html
im pretty sure after all ur fustration 8 dollars wont kill u ...and im pretty sure the condensation from the boiling wont hurt
and i found a free one hope it helps http://www.htcdriver.com/index.php?page=htc-raphael
it's a long trip, in russian, to get to the lcd
http://www.pdacenter.ru/razborka/htc-touch-pro/
You can use Google translate on it. It seems that the hardest component to get to is the lcd. I also bought the digitizer, since my lcd is fine. I'll post a follow-up if I go for it.
Any luck getting the touch screen off and new one on?
I bought a touch screen and digitizer as separate items. I wish I had known that some kind of clear adhesive is supposed to be between them.
A) What happens if you don't use this adhesive?
B) Has anyone successfully replaced the screen/digitizer with replacements on the fuze or touch pro?
Anyone having luck?
Has anyone actually figured out how to install this? I just got what was supposed to be a replacement LCD+digitizer. they shipped the pieces seperate, so I can't understand how to put them together, since HTC seems to only list the part as one piece and there are no instructions or videos anywhere that indicate how to install them as seperate pieces, or get them to connect.
Dont do it!!
Ok, I just recently bought a parts phone on here (a Fuze) and was "just going to replace the digitizer" (Authors laughs, then cries at statement)
Ok, yes you can replace the digitizer without replacing the screen, BUT they tell you to use an oven (you can buy one from HTC they make it available to their techs, so you need someone that can get that for you). If you do not make sure that ALL of the glue is loose prior to taking the digitizer off you will split the LCD.
It is much simpler to get either a parts phone or a screen and digitizer and replace the part. I had to replace my digitizer as the touch function did not work. You can find older project phones in the market section. If you figure the cost of a parts phone (plus you have extra parts if anything else goes out) vs. if you buy a digitizer, then rip a part of the LCD because all of the glue was not disolved, and have to buy either a parts phone or a new phone anyway you will be way ahead of the game.
There are a number of good resources on here as to how to disassemble and reassemble the fuze.
I WOULD NOT RECOMMEND TRYING TO REPLACE THE DIGITIZER ALONE IF YOU HAVE NOT BEEN TRAINED OR HAVE THE PROPER EQUIPMENT - unless you need a reason to sell your spouse on why you need a new phone. "Honey, I tried my hardest to fix it, but I guess it is really broke now, I'm gonna have to get an HD2"
If you have any questions about the process let me know I am always more than happy to help.

Yes, indeed, mike channon does offer a very detailed service manual for the raphael.
Replacing the display on the HTC Touch Pro (Raphael): Some Tips
Replacing the display on the HTC Touch Pro
How To - Tips
1. Collect information
a. Find the Service Manual HTC Touch Pro (Raphael) on Mike Channons's site, the Raphael wiki or you could Google for it. File name is "HTC Raphael_SM_A10 _GENERIC__01 Dec 08.pdf".
Take a look at the disassembly and assembly chapters of the Service Manual.
The following two lists may be helpful.
---
List 1: types and quantities of screws
[SPL no., P/N, pages of Service Manual, description, quantity used in Raphael]
10. 72H01893-00M (see p. 34), black (middle length), 2x
11. 72H02450-00M (see p. 32, 34, 30), black (shortest type), 7x
12. 72H02474-00M (p. 37), black (longest type), 4x
13. 72H02689-00M (p. 30), metal, 4x
26. 72H02865-00M (p. 35), metal, 6x
27. 72H02886-00M (p. 35), 1x torque screw for M/B, 1x
---
List 2: kinds of tape/fabric used in the Raphael
a. Conductive fabric
Self adhesive conductive fabric, parts 14-24 on the SPL. The adhesive backside is also conductive.
b. Mylar
A specific kind of polyethylenetereftalaat (PET) used for electical insulation.
c. Kapton tape
Kapton is a polyimide film which can remain stable in a wide range of temperatures. (electrical insulation)
d. EMI gasket
EMI shields are implemented in a design to isolate one component or section of a device from another.
e. Double sided tape
---
b. Movies of the disassembly process can be found on YouTube for the HTC Diamond.
The Diamond does not have an integrated keyboard, so it is a bit different, but it is good enough to get an idea of the process.
The information on how to replace the screen itself is not found in the service manual.
c. Study the last few stages of the HTC Touch Pro page on pdacenter.ru
(Translate the page into English using Google.)
The display is attached to the metal frame by 4 small pieces of double sided tape.
3. Get some tools
a. Phillips (cross head) screwdriver size 00x50
The right size is 00. The length, 50mm, is less important.
There is one torque screw in the Raphael (SPL no. 27), but it can easily be handled by a normal screwdriver.
b. Plastic stick (to open the case)
The standard plastic stick I had ordered was actually too big. The one I made myself was smaller and proved to be better.
c. Other tools
I did not use these, but if you plan to do more than one it would be a good idea to use the
- plastic tweezers
- ESD wrist wrap
- rubber gloves
4. Buy a display with touch screen attached to it
You could buy the touch screen and the display separately, but I could not find any information on putting them together. Avoid problems by buying these already attached.
5. Replace the display
a. Disassemble following the Service Manual, leaving the M/B unit in order.
Be careful not to break the small speaker cords. Do not move them too much because they are very fragile.
Be sure to keep every piece of tape safe for reassembly. Buying new tape can be quite expensive.
b. For the last stages, follow the instructions from pdacenter.ru.
Press the old display gently out of the metal frame. Move the pieces of double sided tape from the old to the new display, and fit the new one into the metal frame.
c. Reassemble following the Service Manual.
Good luck!
What will fit what?
Will the lcd and digitizer from a sprint version work on an alltel version(ppc-6850)? Or is there another lcd and digitizer that i can use? Im back to the old berry 8703 and its killing me.
spammer said:
if you just find scratches on the surface, then you just need to change the touch screen digitizer. the soldering is requested when you fit it.
But of course, if you buy the one that lcd and touch screen fit together one, then no soldering request.
Anyway, soldering is not such difficult if you has the tool.
thanks

I don't see any soldering involved there. The digitizer is fitted with thin lines of some kind of glue or kit around the edges. I have not seen any documentation on it though.

you can look at the connect flex cable part of your touch screen and the lcd, you will find they are soldered together. Of course , if you don't soldering it together, it will also work, but not as good as after soldering.

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
http://compare.ebay.com/like/220603...fb0fe93&itemid=220603974499&ff4=263602_263632

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.

My HD2 LCD screen broken -- Help!!

My LCD screeb broken yesterday. I have tmobile HTC HD2.But my touchscreen works fine.
Do I need to purchase this one
http://cgi.ebay.com/OEM-HTC-HD2-T858...#ht_2748wt_698
or
http://cgi.ebay.com/T-MOBILE-HTC-HD2...ht_1845wt_1014
Do I need to solder something or is just an easy fix?
Please let me know.
Thanks
Mine too
The links to the Ebay sale you posted are no longer valid.
My screen is broken also, just the touch sensitive glass (digitizer). The LCD is still in tact.
From what I understand the digitizer is harder to replace than the entire screen (digitizer+LCD) because the LCD is glued to the digitizer. There's a video on YouTube someone posted demoing the process.
http://www.globaldirectparts.com/HTC-T-Mobile-HD2-Digitizer-p/htc733745.htm
Has the digitizer for only $57 USD, but you have to order 3 at at time. If we can find someone else that's interested, then maybe we can go in and get one if that's all that you need also.

I have done the digitizer repair, not exactly what I would call a fun time.
Easy to mess up your phone, need to make your own glue or double sided tape (to hold digitizer/lcd/frame together), about 4 little tiny wires that need to be placed correctly when putting the phone back together.
Thankfully the US HD2 does not require soldering the digitizer's connector to the lcd (the european one does), however again this is not a repair job for the feinthearted.
After all was said and done and the digitizer was repaired, the new one had the rainbow/oil effect when under a fluorescent light source, don't know if it is due to me using the wrong digitizer or what, but it did not look good. I had the same issue with a altell touch pro 1 that I purchased on ebay, it annoyed me then and it's back with a vengance.
Have fun, be very meticulous and watch the HD2 dissembler videos about 5 times before you unscrew one screw.

[Q] Display repair: What should I do?

Hi
Ok,my HD2 is broken since October and I'm a student and i just couldn't afford the repairs. All I know is that - it seems like this - the connector to the display is not working anymore (common problem I heard).
But honestly I have no idea what to do:
Money is still a bit tight so I can't really buy a new phone.
On the other I couldn't even figure out what to repair. I know the display is a whole unit (LCD and touchscreen glued together) and somewhere in between is the connector,which lost his contact to the mainplatine.
But all I find are the plastic frames with a connector ( http://www.algogo.com/store/product...er-HTC-HD2-II-LEO-T8585-.html?setCurrencyId=2 ) [I have no idea what digitizer means..i always thought it's the same as the touchscreen itself but that's not true.]
Or I find things like this LCD+Touchscreen or even cheaper this .
I know I need the big connector cable as mentioned in the first link of the digitizer offer but here the connector cable is suddenly on the side and not down to the keys...
Well,but it's the whole display package so I guess I need this...
I already have the right screwdriver for this work but I'm still not sure what to do/if it worth it.
Ok,the 70 Euro plus shipping..that's cheap but on the other hand the HD2 is already a bit old (but I still love Windows mobile and what do keep that).
So..any clues..suggestions?
my suggestion is to go for.. buy any LCD+Digitizer pre-assembly pack, check this videos link
and try by your self..
also many informations about the procedure you will find here link2
or here link3
take your time and you will be successful repair it at your own..
Thanks your these links but the thing is..I already know them and tried it as far as I could (which is why I already have the right screw driver for it). In the end I just scratched it more and more...
The thing is..I'm not really good at this - especially the display removing and heating part of the job. So I thought I could bypass that by simply replacing the whole display unit. Ok,still 70 Euro if I chose the second ebay link but that's way cheaper than the other ebay offer plus really really cheap compared to these send-in repair shops from the internet (about 200 euro then).
I'm just not sure if these are the right components or if there is a cheaper offer somewhere else.
I bought my LCD+Digitizer for 55USD with the shipping costs, from ebay.com.
It was from a China seller, not an OEM item for sure, but after all, my LCD was as a new one!!!
I also needed an adhesive tape like this one.
you should remember that you will need to detach the LCD+Digi from the middle metal plate frame bezel
and the only way is with heat. I tried with a hair drier..
And all went as is should be..
I'm sorry to dig this thread up but I just found my old HD2 and wondered if I could get it back to work.
Of course I need a new battery and stuff but actually it's still ok.
The concerning part is the glued display and the heat you need but now the HD2 gets older and the prizes drop so I saw a complete display (the glass, the screen and the touchpad-layer) on amazon for 60 euro.
Would you go for it?
I'm not quiet sure how to disamble the device but there are videos for that. And then it should work, right? There is no glue or duct tape or anything involved if I swap the whole display-component, right?

From the research I've done you'll need either super glue or 3m double sided tape.

the definitive HD2 disassembly and screen replacement thread

My HD2 finally developed the dreaded unresponsive touchscreen problem this week after just over 2 years use and as I'm now out-of-warranty I've decided to replace the lcd/digitizer myself.
Searching XDA and youTube for inspiration threw up a lot of scattered information, some useful and a lot more that was wrong and misleading so i'd like to establish a thread here with all the right answers provided, in detail.
This should also be of interest to those with dropped phones and smashed screens.
So far I've discovered:
- my unresponsive touchscreen is a hardware (not software) issue; caused by damage to the digitizer cable accumulated over time by repeated presses of the power button, to which it is physically adjacent.
- if the cable is only slightly damaged, a temporary fix might be achieved by pressing on the power button until the touchscreen starts responding again and then avoiding pressing the power button thereafter. ie. letting the phone timeout to sleep automatically and waking the phone up by pressing one of the other buttons rather than the power button.
- a permanent fix involves replacing the digitizer which requires an almost complete teardown of the phone. I'm open to any other suggestions from posters for say, repairing the cable although I haven't seen any as yet.
- although only the digitizer needs replacing, it's easier (albeit slightly more expensive) to replace the LCD and digitizer as a unit, which is the same part whatever version of HD2 you have.
- The disassembly procedure is fiddly with a lot of easily-breakable cables and connectors.
I've already acquired the LCD/ digitizer (part no. 60H00300-00P) from ebay, for £22.99 shipped, which was a pretty good deal as the standard UK price seems to be ~£38. The cheapest I found for the digitizer only (without LCD) in the UK was 11.95 shipped. The difference in price wasn't worth the extra installation hassle for me.
other required items are: a T5 torx screwdriver, a small jeweller's screwdriver set, tweezers, a guitar pick, an old credit card or similar, superglue (or double-sided adhesive tape) and thin (2.5mm?) single-side adhesive tape. also reading glasses or a magnifier might be handy depending on the quality of your close vision (i'm 54 so mine lacks somewhat).
This is by far the best instructional video I have found to date:
http://mperlitsch.hintergrundbild.com/htc_hd2.htm#Zerlegeanleitung
.. unfortunately its in German, which mostly isn't a problem as you can see what he is doing, except at the end as he describes (at length, rather than showing) the final step of superglueing the new LCD/ digitizer into the phone chassis, where i thought I might have missed some important details. Perhaps any German-speaking posters could fill us in on that procedure?
The above website also accompanies the video with some text descriptions of the various stages of disassembly which I will get google- translated into English.
There is another useful-looking instructional site here (hi-res pics, no video):
http://www.ifixit.com/Guide/Installing+HTC+HD2+PB81120+Screen/5651/1
Finally there are also some leaked official HTC breakdown videos on youTube @720p here:
disassembly:
http://www.youtube.com/watch?v=cL-jnUKufC4&feature=player_embedded
reassembly:
http://www.youtube.com/watch?v=t8Q7mXdcJ54&feature=player_embedded
I'll keep the thread updated as I go and I would welcome any help or tips from anybody that has already been down this road.
My aim is to develop a foolproof instructional guide that almost anybody can follow to extend the life of this great phone.
I've read that german thread as well and I'd agree that it does seem to be a very good guide, to read it in english open the page in chrome (or search for the thread in google) and let google translate it,
Step 32 for example translates to Step 32: Now as in step 31 and proceed to the bottom of using each 1 drop of superglue and moisten with clothespins along with the 30-minute fix waiting / drying time. In the bottom right where the flex board stops at the edge of the touchscreen and LCD connector watch film. There, only the metal bridge very carefully and very economical with wet glue. Important: Use sparingly only at the marked positions superglue! Never close the buttons at the bottom, even if the lure still should be as large. It is held there by our HTC special adhesive film wonderfully.​

Thanks, I'll have a look and see where his "marked positions" are. i already figured from the video that he was stressing about the buttons.
As this is the only part that I'm nervous about, I'd be interested in anybody else's experience of sticking the new lcd/ digitizer into the chassis. what did you use? and how did it go?
Presumably HTC didn't use superglue at the factory. Has anybody tried double-sided adhesive tape for this?
EDIT: I've just ordered some cheap generic double-sided tape on ebay, advertised as "New Clear Strong Permanent Double Sided Self Adhesive Craft Packaging Tape".
I'm still waiting for my LCD/ digitizer part to arrive and in the meantime bought another HD2, with a smashed screen, to practice disassembly on.
my own HD2 is currently behaving itself as long as I don't forget not to touch the power button.
i've now received my digitizer/ lcd part + (noname) double-sided tape in the post.
i've also found another XDA thread speaking in more detail about the step of fixing the lcd/ digitizer back into the middle chassis here:
http://forum.xda-developers.com/showthread.php?t=1341927
there is some debate in that thread over whether tape might be a better bet than superglue. the tape they recommend is 3M brand 2mm double-sided, for which I have sourced a supplier on eBay (item #281023942070 -- "3M 2mm x 50m Adhesive Tape Roll for iPod iPhone iPad - Transparent") for £5.99. I'm going to get a roll of that but may still opt for the superglue method ... undecided.
Mine was the same,
After seeing some videos I decided to buy a digitizer from ebay, it looked really easy on the videos. I bought one for 25€ , the ribbon cable looked strange but I decided to go on. After finishing everything the digitizer doesn't respond. I want to test the digitizer alone, any idea? I've access to a complete electronic lab, so there's no problem to use an oscilloscope or whatever.
Thanks in advance

sounds like you might have bought the wrong digitizer. You know there are 2 types, soldered and solderless (plug-in) which have different connectors?
Any pics? How did the disassembly go otherwise?
in the german video i posted, he shows how to reconnect the ribbon cables and test the lcd/ digitizer before glueing it in and reassembling the phone.
