hii !!
my trinity has an lcd problem, it does not turn on , although other functions work fine.
i think it is the lcd socket?? because the black thing that secures the lcd cable fell out and im unable to put it back in. so the lcd cable is inserted in the socket without the black clip. im pretty sure its still in when i reassembled the phone though.
although one of the pins in the socket was previously bent however i managed to make it straight at least i think so. so after many tries, at times the lcd will light up with a dim light, at times the light is brighter, with the touch screen working.
sorry if this is a noob question but i was wondering what needs to be replaced. or if it can be easily fixed???
thanks for reading =) any advice will be greatly appreciated
also the it lights up without any picture. just light thanks
I had the same problem so I sent my phone to HTC repair centre just to find out that they couldn't fix it. I had nothing to lose, so I experimented. Anyway, 4 layers of duct tape will solve your problem. Stick them at the exact place where the black clip was and that's it. Don't give up trying!
thanks for ur suggestion
i tried that but to no avail
the lcd just lights up dimly but no picture, touch screen works
is it possible to be lcd damage, possibly water damage ?
or possibly can it be the mother board ?? all other components work fine, its just the screen
Maybe it's LCD, I don't know.
You have to put it all together and fasten all screws to be sure that my suggestion doesn't work. I must have done it all at least 50 times before I managed to make it work without a problem.

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.
anyone know how/where to get an xda mini II repaired? i'm in italy, but i can careless where it has to go. I'm at the point where i would rather just sell the device for it's workable parts (if there are any)...Today the screen has done a myraid of interesting things...anywhere from blank to thousands of vertical lines....ugh...
ohh yeah...warranty is void....or is time to just move on?
ok...no answers so i thought i would add some images ...anyone seen this before?
Mate i had a similar **** up a while back ...I did a HR and it worked fine..for me it was caused by a Overclocking software [Dnt want to Name it ]
If this dnt work try the Batt out and back in trick
Call ur Local service Center...
mine looks exactly teh same! but it happened after i tried to replace my housing, i screwed up the little gold prongs where the ribbon connector from the lcd plugs in...****! any ideas on how to fix? im the us so service center isnt really an option, and id ont want to send it off.
hi i had the same problem with my magicians, after i changed the housing. i found the problem with my device was that i had not plugged the screen back in properly. all i did was to ensure that it was pushed in properly before i clipped it back in
Menappi -
I had the exact same issue. I reopened the casing WITHOUT disconnecting any cables. I flipped the screen's ribbon black lock up, while maintaining pressure on the ribbon so that it does not pop out. When the black lock lifted, the preasure of my finger moved the ribbon further in . I pushed the black lock down, reassembled the device and ... PRESTO!! the screen works perfectly... and chumps on the bard advised to buy a new screen!!
Good luck
Hi All,
seems, you have problem somewhere in display connector. However, sometimes I see similar picture on physically broken displays, let's imagine, you were careful ad didn't use a hammer during housing replacement.
There are two possibilities: at first - try to remove and re-insert display cable (I hope, you know. how brown lock works). If there is no success - try again. At second - some wire on flat cable may be damaged. Sometimes, good technician with soldering iron can fix it, sometimes not. And if you used force, removing cable, board connector may be damaged too. However, only the experienced man can find it easily.
So, try to carefuly re-insert display cable. Try several times. If you are unsuccessful, you, for sure, need an experienced technician to fix your device.
I hope, you are not enough mad to send device for repair to Russia
Hi all,
My screen digitizer was in a bad shape, so after doing some research I ordered one off ebay and got it today. I used the guide on http://www.pdacenter.ru/razborka/htc_tattoo/ to disassemble my phone, managed to successfully replace the digitizer and put everything back again. But whenever I turn the device on now, the only thing I get is the backlight of the LCD and nothing else, no boot animation etc and it hangs like that forever. What could cause the problem? I'm really desperately in need of help. I checked the connections of the LCD more than one time and they look in place.
Thanks a lot in advance.
If you have getting only backlight, this means that you have properly connected ONLY power source of your LCD. Pins for video input are not properly connected. Call from another number yours after 3-5min and if phone rings problem is only in LCD. Try to clean pins with Ethanol 96% and dry it with a dry cloth. Then put all back and check. This sounds stupid but it helps, clean pins with !eraser for paper! people do that with pins on PCI cards.
Good luck, if you fail go to service they will do that for 5 min and 5$.
Hey guys! I have a problem with my Blackstone....
After a while of using it my touchscreen does not respond anymore....
It just stopped working. The display works exept the touch....
any help wold be much appreciated...
touchscreen
I have the same problem. Touchscreen do not response anymoore, I tried to reflash the rom, but it did not help.
you probably have the digitalizer broken.
I got this changed once about 1 year ago (under warranty). It seems to be a big issue on our old devices.
If you are out of warranty, it's probably not worth to send it to the service.
You may try yourself following this thread
Sometimes if you paste a tape on the screen and try to separate the 2 layers of the digitalizer pulling the tape slowly, it may work for a while (temporary fix).

Hi guys, I had this problem one year ago. My warranty didnot covered such thing and it was too expensive to repair it, so I have read all forums and found the solution. The problem is indeed in the digitizer however it is not broken just the covering plastic screen seems to be pressed to it and generating a continuous touch so when you touch with the finger nothing happens. There are two solutions to detach the plastic screen from the digitizer - either put tiny plastic card below the screen from the edge or use a duct tape on the screen and pull quickly - this step may need to be repeated several times until the two layers detach.
I have done both processes and it works. With the duct tape it is safer but the problem appears again after some time, with the first approach I don't have the problem anymore.
Hope this will help you.
yeah, I know it's old thread, but could you please elaborate on this .. ?
covering plastic screen - do you mean, the layer that is in front of the digitizer, the one you actually touch ? that stuf is glued hard, I dont see how you could place tiny plastic anything from the edge, that means that you need to unglue it with hot air .. ?
I am having the same non responsive TS problem, but I dont think that it is broken also. only things that could go wrong are ZIF connectors, and the digitizer integrity, which is mostly not the case cause of the firm plastic surrounding it.
please respond, you could use a pic with an arrow to show me cause im in the middle of dissasembly process. tnx
Hi i have a htc hd2 with gingerbread, my brother replaced my screen and it work fine the first time with the only problem that you see light in the corners because it didnt fit properly to the frame,
2 he tried to fix it so he used some glue when i turned on it freezed when booting and the color white was showing pink
3 he took it apart again to put it like the first time and it work but now the speaker stoped working so i used it like that for 3 weeks
4 then i told him if he could check the speaker so he took it apart again with no luck and now it freezes again when booting we have tried to find the problem with no luck
do someone have any clue for what is causing the problem please help me
another thing since replacing the screen the first time you turn on the phone has to be with the ac cable because it wont do nothing with the on button after that the button works fine
hope someone can help me and sorry for my poor english
it seems like you might have a loose cable connection somewhere, like the loose flex ribbon or broken sockets. Your only bet is to disassemble your HD2 and assemble it,but this time around, you might want to do it according to proven methods and go step by step. Refer to the links below to help you:
http://www.ifixit.com/Guide/Repair/Installing-HTC-HD2-PB81120-Screen/5651/2
http://pocketnow.com/hardware-1/official-htc-hd2-disassembly-assembly-training-videos-leaked
if proper disassembly and assembly do not work, then im afraid you have to replace your flex ribbon or get a new screen. it is often hard to troubleshoot what exactly is causing the problem unless you see a visual break in connections. take a really close look at all the connectors that are involved with the screen: the locks, sockets and cables.
do try the above and good luck. hope this helps.
