I wanted to change the touch screen on my QTEK 2020 and I bought a new one a few days ago. I opened tha PDA, but when I tried to pull the touch screen off, I damaged a slim orange cable on the back of the screen. Specifically, I pulled a black sticker and it took along the two cables that were on the circuit on the screen. I don't care for the touch screen's cable, but for the one of the screen. I have scratched the insulation on the cable and I have a question. If I just put over the circuit the nakes cable and glue it a little belower, would it make connection? Or have I to solder it? And How am I going to soldier a cable like this that's naked from the side that I don't see when I put it in place, without even melting and damaging for good the screen or the cable itself? I have some pics, too for you to see and understand what's going on. Please help me, as I am a young man with prospect and I want to learn things like this and do stuff more than the usual.
OK, I couldn't wait for advice so I soldered both cables. The screen turns on and it needs to be aligned. I tap the screen, the touch screen works, but when I finish the alignment, it starts from the beginning, the cross in the center. It asks to be aligned constantly. I haven't assembled the PDA, I have it like the pictre below. Is this the problem it doesn't start, or do I have to put the touch screen somehow differently? I have it centered and tried to align tapping a little upper, lower, left, and right from the cross, but nothing.
Please HELP!!!
OK, no worries! I fixed it! It took me all evening, but I'm completely satisfied. Solder this, solder that, make a bridge because a connection was damaged with all the scratching, but it worked!
cong. dominator happy that you have finally fixed it :wink:
Thanks Kbantikos my boy! And here's the bench and the heat tool I used! That's the only that I have. No doubt it took me 4 and a half hours to complete.
Congratulations! I'm not kidding, saw a lot of "homework" results, in some cases, display was damaged beyond repair.
You get the working display, so you are lucky .
Thank you, my friend! I didn't believe my eyes when it booted! It still works fine, even if it fell off my hands one time!
my touch screen is really quite dull / lacks brightness even when on the high setting
i've aquired an XDAII that isn't working but i know its screen was bright when it was working
my question is: what do i need to be looking out for / be carefull of when i replace the screen
what would you do differently?
thanks
Larry
You'll definitely have to look for that orange cable that's not of the touch screen. on the back side of the screen there should be a black sticker. When you try to pull it over, it takes the cables, too. So pull it from the side of the touch screen's cable only. You are gonna need to solder the new touch screen for sure, just placing it won't work. Scratch the side of the cable that's going to be placed on the circuit on the back of the screen so that the metal contact on both (touch screen's cable, circuit) is naked. Put solder on the circuit's contacts. Then put the cable on top of the circuit, but a little lower. Now, burn the solder holding the cable steady and connect that way all four contacts. I hope I was of a little help, observe my pictures and good luck!
Just about to try this myself.
Touch screen bought from - http://stores.ebay.de/hitechhk. Arrived within 1 week.
Removing the black tape on the back of the screen, even very carefully, pulled off both the connections for the touch screen and another connector (the back light I think)
In hindsight would recommend only removing the tape around the touch screen connector.
As soon as I find a small enough tip, will resolder everything.
Detominator7, how did you change your digitizer? cause i need to replace mine too, but the seller is talking about soldering it. i already open my pda and all i can see is there is only plastic cable. how do you solder on plastic?
Your touch screen might have a cable that plugs into a hole and does not require soldering. You know, like the fans we use on PC.

What kinda adhesive do they use on the back of the screen
I'm talking about the clear glue type adhesive on the back of the screen in order to hold the ribbon in place
here's a pic of what I'm talking abouthttp://blog-imgs-3.fc2.com/i/n/u/inuchanbt/CHT9000_dismantle12.jpg
The gold/copper ribbon glued to the screen
had to replace my brothers screen about 3 times and now its barely stickin
it's a kinda like double tape. u can find in office stores
I hard reseted my O2 XDA II & I had surprised the screen aligning can't be passed.
Can somebody help me with ROM Flash or maybe some hardware tricky?
I use WM5 from C_Shekar.
PM me if anyone replies this message.
Thanks, Berns.
Dear friends,
My offer to the forum, a step by step guide on how to safely disassemble your precious Trinity. You might ask of course, why should I do that on a very expensive electronics device? Well I personally had to do it in order to remount the phone in a white casing because my black had peeled off after two months of ownership and I did not want to send the phone to HTC. Also because it was really fun.
My best regards to you all.

What a great tutorial !!!
Thx a lot, it is the best one.
GREAT!
Thank you very much for this very helpfull guide!
Good !
Hi !
Thanks for this great guide !
Very good work !
Concerning the tutorial that I have written any questions are welcome !
Regards !
Great
Thanks for the tutorial
Great tutorial! Thanks! I actually just had my Infrared window pop into the phone on me today (half way at least). I want to try to get it back to normal again w/o sending my phone to HTC. Apparently they have a swap program, so who knows what kind of condition the phone you receive will be in.
Where did you get the original white housing? I might be interested in switching that also since it will be half-way apart already.
Dimanto,
what a super guide. The photos and layout are really good.
Now available in [pdf]
Dear friends,
I have converted the "How to disassemble Trinity" guide in [pdf] and is now posted in xda-developers. I think that this format is more proper because the file size has reduced a lot. You can find the rapidshare link or the attachment in the first message of this post.
Regards
HTC P3600 Trinity - Inside - OUT!
Grate post really thanks!!!
You may take a look to these photos about disassembling htc…

Hello, great guide, only one question, when detaching the cable from the motherboard for the LCD screen you commented it was a little more difficult and to pull up the black lever. Can you elaborate on this part and also advise how easy it is to replace and close once the cable is reinstalled. I have a crack in my LCD screen, so probably wont have to go as far as you. Have accidently broken this type of clip prior and want to be careful. Thanks
LCD Panel and Digitiser
Hello dimanto, any thoughts on how the LCD panel and the digitiser fit together prior to me starting on this project. Thanks.

Hello my friend. Actually it is not so difficult to pull up the black lever so you can then easily take out the screen cable. This is rather easy, also to clip it back on. What you have to be careful of is when you unclip the LCD screen cable from the the M/B, then when you pulll out the LCD screen from its postition, do it very carefully because it is very easy to accidentally cut the LCD screen (ribbon). So don't worry about the clip.
Regards!

Well I do but if you are buying a new LCD screen don't bother about it because the digitizer is already on the new screen. If my reply is not helpfull just tell me what part you are changing exactly. Basically the digitizer is a small glass attached on the LCD screen connected to her via a small ribbon cable. If you need something more just ask.
Regards!
thanks dimanto
but can you please choose tools which you used from this page
http://cnn.cn/shop/tools-c-71.html
because there are different sizes and types of tools

This is exactly what happened to me. I broke this little black clip and now my phone is useless. Where did you get another one? I just cannot fix the flat LCD cable anymore to get a proper picture on LCD (now it's either inverted or screwed up or totally missing).
PLEASE HELP! I can't live without my Trinity
Hi,
last week i wanted to change the case from my MDA Compact.... I find a instruction how to remove the case. Some threads attached this for example: ( http://forum.xda-developers.com/showthread.php?t=291808&highlight=case ) the file "disassembly.rar". This instruction is good made, with good pictures... thanks for the author.... BUT!!!!! i think there is one part i am not agree.. what must be improved.... in my opinion....
Problem:
look at page 15 (picture 15) at this chapter the author explain how to disconnect the board from the case. Therfore you must take away the two little screws and disconnect the flat cable from the left side (green line).... oooooohhhhhhh!!!!!! STOP!!!!!!
To disconnect the flat cable you must take away a little plastic part, what normaly get damaged, but not only this.. there are sooo thin connections, that you become big problems when you want to reconnect this again. If this tiny little connections get bent you normaly get bad connection or short circuits and your display doesn`t work anymore.
Result:
Don't disconnect the flat cable from the display!!!!!!!!!!!!
The problem is, how to take away the board from the case, to reach the display. When the 2 screws are out, the board only hangs on two parts, the (bad ) flat cable for display and a flat cable for the buttons. Now, don't disconnect the cable for display (i now, i repeat myself ) disconnect the flat cable for the buttons on the right side. This is a very easy mechanism, what is easy to disconnect and to clip again inside. Than fold down the board (page 16) on the right side and not on the left side. Now you can reach the display...
I hope this helps to people who want to change the case.. and i hope this rescue the life from some Magicians .
Greetings........
Help !
Hello my friend.
Unfortunatelly I have not read your post until I completely f... my display flat cable connector exactly as you have described.
I'm still not able to find out how to recover this.
Do you know some place where I can find this connector ?
Please help.
Thanks in advance.
Regards,
Eduardo
this thread must be pinned. thank you
summarized:
when removing the front case,
do not disconnect the display's flat cable, remove the buttons' flat cable instead to prevent the display from a possible damage.
@bkbone: sorry, i have no idea... i am happy tht i dont must to change this connector. I looked very carefully at the connector to see which wire make the problem. This is very difficult because they are thin like some hair. I make some photo with my digital camera with the digital zoom and saw where is the problem.
I hope this helps you to "reanimate" your Magician again.. wish u all the best...
Greetings...
P.S.: otherwise.. maybe u can ask her: http://www.mrsdewey.com )))))
Thanks thats a valuable information.........this thread should be pinned.......
u are a bit late buddy. because i have screwed up my device already.
while trying to dismantle i accidentally hit the microphone and it no longer works!
i have to use a bluetooth handsfree all the time.
is there any way i can fix the microphone back?
if i had this manual earlier, i certainly would have taken care of this stuff and not have killed my magician.
thanks
Ok I need help from the gods of xda
I dropped my tilt the other day. When I picked it up everything seemed fine, yet the screen was completely white. No signs of cracks or a broken lcd. So I've tried the following: Soft reset, Hard reset, took out the battery, took apart the phone and disconnected the lcd and then re connected it. Still the same problem. WHITE SCREEN!
I can still receive/make calls, when i touch the screen in places where i remember the menus to be it still responds due to the noise, also the open and close noise still sounds.
The phone was bought new on Ebay, so i don't have a warranty through them or AT&T. After much research I hear people saying the same has happened to their phones as well and that there is a ribbon or flex cable problem. Something about still giving power to the LCD but not data, thus the white screen.
Now what I dont understand is do I need a new LCD because it has that ribbon/flex cable on it???? (link)
or
Do I need this product?(link)
Both contain a "flex cable" so im confused and frustrated, someone please help! any ideas would help

hi there, would it be possible to post the link to ebay item? i also need a new touch-screen.tnanks
I am curious about this as well. I have a friend who has a hermes and he mentioned to me that that his screen was starting to go white like explained here. I look at his phone and I also noticed that the bottom hardware keys were not working at all.
I am wondering if this same ribbon cable for the LCD would also be the same one for the bottom keypad and if I fix the screen the keys will become active again.
Anyone have any experience with this?
Thanks,

Tuck in for a long read and perhaps no single answer for all cases:
http://forum.xda-developers.com/showthread.php?t=303872
In short, yes the d/pad cable and LCD screen connections are linked which is why it is not uncommon for the white screen to show up when the d/pad is not working.
To the OP - I would just point out that if you get the white screen after a fall it may just be a loose connection at the d/pad and no need for new parts.
Dismantling instructions here:

But let's not start discussing the white screen here, please use the first link I gave above if you need to post.

a user i dont recall now his name,fixed is whitescreen by replacing the camera,open the device and remove the camera module, reassemble to test.
My wizard was slammed with a trunk lid. The clear screen is fine, no cracks, the housing has a scratch where it hit the lid. The lcd screen is half ok. Now I said all that to say: I bought a screen, here is the link:

Now that I have this, it doesn't look like this is what I need.

Can someone look at this pic and tell me what I should have gotten?

My understanding is, You got a wrong part. What you got is a digitizer, it is the one used for touch only and will not be suitable for the type of repair you need. What you need is LCD. The screen on most resistive screen devices consists of 2 parts - 1 LCD and 1 Digitizer attached to LCD by a layer of fine gel and connected by a flex cable, then the whole assembly is connected by a flex to the mainboard.
My recommendation would be to purchase the entire assembly, get a service manual and replace, however, if you had problems deciding what part you need to repair your Wizard, I say take it to the professional.

The way someone is opening and attempting to repair their Wizard on that video is what keeps me employed. Watching someone open their device with screwdrivers and then attempting to re-connect the flex and forgetting half of the screws gives me the creeps, not even sure whether to laugh or cry. Would love to see the repair actually working, rather than someone claiming they found the way to do something without demonstrating any result.
