oh, is htc tinity...
If You`re lucky it`s just a loose contact. If You can still hear the sounds from the splash screens I`m sure its nothing worse. Had this too and the fix is really easy once You`ve done it. I had to do it numerous times until I had a good solution. Look in the general trinity subforum, there`s a post on how to disassemble the phone. You have to do steps 1-5 to get the back cover off.
Then You can do an easy test:
- Put the battery back in again. I used some paper cut to size as underlay just to be sure not to accidently short anything should the battery move from its place.
- Hold the phone in such a way that You can apply light pressure on the battery so it stays connected. Now You can power on the phone.
- Apply some light pressure on top of the lcd connection cable (marked red in the disassembly guide) and see if You have a picture again.
- If this doesn`t help try to apply light pressure with a plastic or wood piece from the side where it vanishes in the front cover. In other words play a little bit with pressure direction.
If You get Your picture when applying pressure everything is fine cause all You have to do now is to put in something to polster out the back cover (or side cover, depending on where You pushed from when the screen came back alive). There is a small soft black sticker on the back cover that applies some pressure by default, use this as guidance. First I just rolled a piece of paper and positioned it there when I closed the cover. Didn`t hold for long. Finally I applied a sticker used on furnitures to protect wood floors. Same as vibration dampener stickers for loudspeakers. Just cut to size, stick on top of the old sticker or into the side housing and You`re good to go. Never had a problem with it again.
It sounds far more complicated as it is and You should really try it. I wish You it`s just a loose contact.

Hey guys. I have the Telus HTC Touch Pro2, and I have noticed a problem. The part where the touch screen half of the phone makes contact with the keyboard part, causes a scratch on the keyboard part. There was plastic on this part before, but I removed it, and now it is scratching. I don't mind this, but just wanted to warn ppl not to remove the plastic.
I will post pics tomorrow.
I had a little piece of plastic just on the right side of the keyboard. I removed this, because I tought I missed it with unpacking my TP2. But now there is a little woggle(? mean little space between screen and keyboard), so everytime I press the screen on that side of the device I can feel and hear the two parts coming together. It's really annoing and it started when I removed the little piece of plastic. For my feeling it's a last fast hot fix by HTC.
But i don't see scratshes yet. I can see dirt on the left and right of the keyboard where the sliding is, but I can easily remove this. But on the longer term, I think there will be permanent 'dirt' aka scratches on both sites....but hey, when you don't want this to happen, put your device away and don't use it
Scratches fix.
As soon as i opened my TP2, i knew the clear plastics were for protection so i left them. In time the one on the right started to peel itself off. THE FIX... I removed it completely and colored it BLACK with a Sharpie Marker, pulled out some transparent scotch tape out of my drawer and carefully traced/cut it out with a sharp razorblade. Carefully stuck it back on and VOILA! A perfectly new replacement a-la' Jerry Rig! Maybe you can cut out 2 pieces ontop of one another to reduce the play when closed? Time = Approx. 10mins.
Hey guys. Yea I just wanted to leave this as a warning to other tp2 owners who thought the plastic was just packaging.
I can't take any pictures since the only other camera is a phone. It dosen't capture the scratches properly.
I left the stickers on. However, as it turned out later, one of the stickers wasn't applied properly. Eventually, the sliding motion caused that sticker to come off and bend just a little at one corner. I cut the bent part off, and the whole thing came of a few days later.
When you get your phone, make sure those stickers are applied properly, and squeeze out air bubble from underneath if needed.

Did a search can't find anything specific to my issues.
So I had to replace my amoled screen (Samsung brand), did the replacement everything works fine. But...
now it seems my touch screen has a mind of it's own. It will jump out of apps on me or it's favorite is to jump to the recent apps screen (the screen when you hold the home down). It first seemed to do this when I held it's sides with a little pressure, now it's doing it less. Now it jumps to the screen when I gently set it down on it's back.
I have opened the phone back up washed my hands with dish soap, then disconnected all the ribbons and q-tipped them with rubbing alcohol to clean any oil off. (this seemed to help the side squeeze issue)
I also applied clear tape to the back side of the new screen like how it was on the OEM screen since it didn't come with any kind of shielding like to OEM screen (ie that weird metal fabric like tape).
I still get issues and am not sure what it could be or I could do, taking it to VW is not an option.
Oddy enough, hitting it seems to help it, I am not sure if something is shorting or what it could be. I have removed the screen and reset it back on the touch pad still nothing helps.
I am about to try cm7 to see if it's a software or hardware thing but I suspect hardware.
Thanks guys
Try a new rom, like you said. This will 100% determine if it is hardware or software. If it still jumps around on cm7, then there is something wrong with the hardware

I don't know a great deal about replacing hardware on a phone, but is it possible that the screen type is different than the stock type? Some Incredibles have AMOLED screens and others have SLCD. I know with computers, if you replace a part that't not compliant with the original then you have issues.
So maybe the screen you put in isn't compatible with the rest of the hardware?
Just a guess...take my advice with a grain of salt lol
No its the right screen, like I said its the Samsung screen just like oem, the slcd is a Sony product used on 2nd gen dincs. plus the screen and the digitizer are two different parts, the screen is not touch sensitive.
Ah ok. Sorry...like I said, never messed with changing phone hardware....was just tossing out an idea.
I've repaired laptop parts like the LCD, touchpad, and such and had issues with the parts not being exactly the same as OEM, that's why I was asking.
It sounds like a loose connection to me... I havent had any problems with my glass unless its greasy or something. It could also be an issue with the touchpad (button), there is a rubber piece surrounding it that apparently MUST be there... Not sure what would happen if I didn't replace it tho I didn't wanna test it out
So I CM7'ed the phone, it defiantly runs better but it does still bug out.
seems to do it more at work when it's set on my plastic type desk.
I'll pull it apart again and double check the rubber gasket, blow out the optic track button and shim the ribbon connections.
seems something is defiantly shorting just a little bit and it all seems to happen down at the 4 menu buttons side of things
so I pulled it apart one last time. removed the screen and reset it in the case, this time for what it was worth I tried very hard to make sure the screen was mounted as high up toward the top as i could for what it was worth. I also made dbl sure the screen was then firmly pressed back in place and all edges were nice and recessed into it's case.
put the mother board back on and dbl checked all the ribbon connection to make sure they were nice and securely seated and not crooked, then snapped the ribbons down.
I also extended the little grounding? fingers (the ones that press against the copper pads) to make sure they would be firmly in contact with the copper pads. I only extended the ones down by the 4 menu buttons.
I con report it's been about 36 hours and nothing has bugged out yet.
not sure exactly what the issue was but i'll keep you posted if it comes back.
i have replaced the entire casing for my wife's T7373. all seamed to go good. when the phone boots up it is stuck in landscape mode. as if it not seeing a switch or trigger to know that the keyboard is in. also the keyboard lite stays on.
i have taken the phone apart again and still i am not sure where the switch is. all i can see is the metal contact ramps on the ends of the slide.
Any help would be great. "wife not happy"
thank you

The sensor is magnetic that 'senses' whether or not the keyboard is open.
iFixIt.com is a great site to help with teardowns/troubleshooting.
thank you , that joged my memory. well at least i hope i can get it fixed or the wife will kill me....
I also need to replace my case, the silver colored edge has cracked in a few places. Might I ask where you got your replacement case from? Any tips you can give from your experience replacing it?
for the replacement of the silver case can you find at http://www.amazon.com/Silver-Housing-HTC-Repair-Replacement/dp/B0052QW60Y
and at http://shop.brando.com/htc-touch-pro-2-replacement-back-cover-silver_p04432c1050d039.html
i got mine off e-bay http://www.ebay.com/itm/370526944677?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649
had all the parts i needed, everything worked well. only trouble i had was the the magnet for the screen rotation. remounting the brass screw inserts was fun, what i did was use one the longer screws same size. and heated the brass up and screwed the brass insert in.
other little tips. there will be little plastic parts and need re-secured. i just heated up a end of a T25 to melt the little tabs.
have fun it took me about 2 hours and , had to take part the phone a few times to make sure i got it all right.
Hi
Please can anyone tell me which bit of the inside of the phone (or the back cover?) relates to the capacative button brightness?
I changed my back cover from black to white and after doing so the middle button of the three is VERY dim. It looks like it's not lit at all but if I look at it in the dark it is actually still lit but extremely dimly. I was really careful when taking the phone apart but I must have disturbed something that controls these buttons. The two on either side are nice and bright as normal. I have no idea which bit I should be looking at to try to fix it.
I'd be very grateful for any help.

FIXED
In case anyone stumbles upon this in the future with the same problem the fix was really simple. I located the flex with the lights attached at the bottom, lifted it up and there was a thin black sticky band underneath which I assume was used to hold the flex cable down. Part of the black tape had covered the light, therefore making it less bright. I used tweezers to pull it away and lay it flat and all my lights were of equal brightness again. Simples!
Hi all,
i'm very disappointed because i'm just breaking my screen when my zenfone fall of 60cm.
LCD is ok but screen is dead
On ebay i know you can find only the screen with kit, and LCD + screen
Does any one have advice for replacing the screen or screen + lcd? (video or pictures).
Asus France ask me 180€ to change that
thank for your help...

I ordered a screen replacement on AliExpress. I've only cracked the glass on my phone, but I don't think it's possible to replace the glass on its own. (Unless you have the hands of a neurosurgeon and special equipment.)
Tried changing screen today, but it requires a complete disassemble of the unit. I managed to remove the back and disconnect the components, however I wasn't able to remove the battery since it seems to be glued (?) in place on one side. I even tried using quite a bit of force, but eventually I chickened out since the battery started bending. I have no idea how they do it so easily in the video. If anyone here has managed this disassemble I'd be very interested in getting some details.

Try using a hair dryer on the battery for a minute, but keep moving the hair dryer up and down, to spread the heat all over, this should make the glue soft enough to make it easier to peel the battery off.
Finally managed to replace the screen. This one was really difficult to repair compared to the previous phones I've worked on, but maybe in part because there are no complete instructions out there yet. Lots of glue and tape holding it all together.
The battery isn't really glued, but rather held down by some sticky plastic. (Kinda like chewing gum.) I don't think heating will help here. I used a long, flat plastic object to reach underneath and loosen it from the battery.
I forgot to take pictures, but here are the steps I took. You can find some photos for the first half of the procedure.
Remove 14 screws from the back cover
Carefully remove back plastic cover (double sided tape on center)
Unplug the three connectors going to the top PCB/SoC (these are screen, SIM/SD and battery)
Remove speaker (black piece at the bottom, nothing is holding it in place)
Remove bottom PCB: flip up the little black switch to loosen the connector cable next to the battery, then unplug the wire going to the top PCB, then you can remove it. Vibrator piece doesn't need to be unplugged.
Battery can now be removed, but is as mentioned fastened very well. Try to pull it up on the left side to reach under it.
Unplug digitizer connector on the left side of the top PCB. Just peel off the yellow take and pull it out.
Peel loose the part of the metallic shielding that fastened the top PCB to the surface under where the battery was.
Top PCB can now be removed, start from right side.
Peel off the little "sticker" the digitizer connector goes to. This is probably part of what you're replacing, so it doesn't matter if you destroy it in the process. Otherwise try heating it.
Screen can finally be removed. It's removed from the front of the phone, same as for Zenfone 5. Start at the bottom. It's fastened with glue along all sides. If you're hoping not to ruin the LCD while removing the screen you will probably need a heat gun and extreme patience.

Just cracked my phone. :crying:Thanks for the instructions. Before I decide to do this, are any of the adhesives necessary to put the phone back together?
Yes, order some double-tape for cellphones.
Glad I'm not the only one that succeded althought I scrapped the battery in my case .
I followed mostly the same steps but for anyone that want some pictures, I posted them in another thread

Can asus ze550ml screen will fit to ze550kl model
@Ptselv: probably best to start a new thread rather than hijack one that is several months old.
And to answer your question: No, a ZE550ML screen will not fit a ZE550KL phone. My suggestion: search AliExpress.com for "ze551kl digitizer" and you'll be likely to find what you need.
