Hi all,
I am at my wits end on this problem if anyone can offer any adivice it would be greatly appreciated. So let me give a recap of what has occured thus far. The water damage tag for some reason turn pink thus i am unable to get warranty exchange. I am pretty certain that the phone has never been expose to any water of anything of that sort, but i do live in houston, tx so might be humidity or what not that cause the tag to turn. Anyways.
1. This all started after i flashed RRE 5.2 RC3. Initially after a successful flash everything seem normal and fine. Then next morning i woke up to a frozen screen with many verticial lines running up and down the screen was almost unreadable. Initially i thought it was a bad flash or just random lock up. I did a hard reset and tried to enter the bootloader. Black screen, it does seem like the backlight is coming up but nothing on the screen. I can hear the phone power on and boot successfully into windows. Activesync connects i can browse the contents of the phone.
2. After flashing to stock att rom and stock htc roms same symptoms. So at this point i am thinking crap bad LCD screen. so I ordered both the digitizer and lcd screen for good measure. I replaced them hoping that a bad LCD was all. replaced both screens and i powered on the phone. same problem. black screen. The phone still powers on and boots into windows. Activesync still connects and i cna still reflash the phone.
3. I work extensively and do both desktop pc and notebook repair. I am not new to dealing with small electronic repairs. but at this juncture i am unable to identify the cause of hte malfunction. i am hoping maybe some of the gurus here might be able to shine some light on the subject.
Thanks in advance for any help.
I would have followed the same approach; your description makes it sound like it might be some kind of backlighting issue at first read. I'm inclined to think it might be a cold connection (bad connector) on the main board.
Silly question, what happens if you power up the phone with the keyboard exposed?
*EDIT* Not sure if you have been here yet: http://www.mikechannon.net/
Cheers,
i just tried to power up the phone with keyboard exposed. Powers up the same as with the keyboard hidden. Still boots up fine but black screen. I already have the service manuel dowloaded. i have checked around with several repair places both local and on the web. Seems like no one has any parts for the att fuze/touch pro gsm except for the lcd and digitizer and a speaker.
its quite possible that it is a main board but as the same time it might be something as simple as a ribbon cable. i have contacted htc about doing a possible repair and they want wayyyy too much for just a main board repair almost $400 USD.
Anyone have a bricked/ non working touch pro they would like to sell ? =P

Click to expand...
Click to collapse
Could be a bad ribbon cable ... and firmly pressing around the front/back of the unit shows no change?
pressing the phone front and back show no changes to display. in a very dark room I can see that there is light emitting from the display but its just the screen is not displaying anything visable. this occured both before and after i changed out the screens. I'll do another visual inspection of all the boards to see if there is any bad resistors burnt out circuits etc.. but i didn't notice anything mentionable during my first 2 inspections. Maybe 3rd time is the charm.
Thanks for all the feedback thus far Hilaireg it is quite appreciated. All this venting has at least made me feel 1000% better than after i replaced my lcd and still same problem at least i don't feel like a complete idiot!
Sorry I couldn't be of much help ... you've done all the steps a seasoned hardware person would do.
Do post back to let other folks know if you get it back up and running.
Cheers,
you have a pm fkoong.
I have possibly the same problem. Phone got wet, dried it out for 2 days (in a container of rice). Phone worked but had "water marks" on screen that disappeared after two days and everything was fine for about 2 weeks. Then one day (happened to be humid misting rain eve in Charleston) the screen is blank (hint of backlight only). A soft reset and it seems OK for about 1hr, then blank again. The hard resest screen displayed OK (readbale text etc), but didnt work. But as I write this, I retry to document it results correctly and the NATF ROM is reloading and the screen works! We will see how long!!
Well.. not that long, the end of the ROM load and it went blank again, seems like a video driver problem. The Press VoluP to boot does show some red artifact.
Trying hard reset again (No SIM no uSD)
The NATF v4.4 loads and gives me the Tap screen, Align Screen, stylus, loads customization, opera, tf3d, then loads a bunch of files under ...... and then the screen goes blank again, seem like what happened last time, so Ill try loading a fresh ROM copy... later
Hi.
My Touch Pro is acting somewhat weird.
The other day I walked in what best can be described as moist weather. It wasnt raining but it wasnt dry either. I had my headset on an the radio running on my touch pro. No problems. Later that day it freaked on me.
The backlight wouldn't turn on no matter what i did. Until i soft reset the phone. Then it turned on until it went to sleep by itself. Then the lcd turned off but the backlight stayed on. One hard reset later and it was fixed. A few hours later i recieved a text and it took forever to open the messaging app, and as soon as i startet typing on the keyboard it kept turning the light on and off, and the caps an fn lights cycled on and off also. I had to turn to the soft keyboard to answer the text. And the phone now seems REALLY slow and unresponsive, like cpu cycles are being used. But nothing is running on the phone.
And thats basicly how its been ever since. I can se both the water sensitive labels have turned red, and i sure that its because of my walk outside.
I've tried hard resetting, flashing the original rom, flashing a new 6.5 rom, drained the battery completely (not that hard because the backlight wont turn off) and off course fully charging the battery. Nothing seems to help.
Any ideas of what to change, or ways to fix it. Theres no warranty on it, and even if there was they wouldnt touch it because of the water sensitive labels has been triggered.
Any help is appriciated.
Im thinking of buying the tattoo instead if it aint feasible to fix it, but im really hoping cause im not sure i can live without the hardware keyboard.
so i dropped my touch pro, and the battery was still in place, i checked my phone and the screen was black, i tried taking the battery off, resetting it and nothing.. i was wondering if theres anyway to get it to work..i can still recieve calls and get texts, but obviously cant read them :/
ok , now the phone turns on and everything (still black) and i can hear the voicemail "ringtone" but now it doesn't even wanna receive calls, they go straight to voicemail, and before i was able to make calls by using the qwerty and hitting the green button but now it doesn't even do that?.. any suggestions?
If it ain't under any warranty/insurance best thing to do is try popping it open, and reseating everything. Possible a ribbon cable popped out. Worse scenario is the board inside cracked or a chip popped out. With a little searching here and on Bing you can find seceral service manuals for our device. Good luck! I've never done it myself.
I unfortunately smashed my screen and ended up having it replaced by buying an oem screen from eBay. But whenever pressure is put on certain parts of the back of the phone the screen just cuts off. It's got to the point where the phones just sitting there or its in my pocket and the screen will die (the phone is still on as I can see the notification light blinking but this isn't always the case) and I have to push the back of the phone and reset it and after a few attempts this will usually work. Any idea what it could be? Faulty screen? Dodgy installation? (I've checked numerous YouTube videos and as far as I can tell nothing is missing).
I'm tempted to just send it to Google and see what they say as I'm getting pretty fed up with it constantly dying but thought I'd try here first
Thanks
Okay so yesterday I came back upstairs from doing some stuff downstairs. i pulled my phone out of my pocket and bam, there's a white screen with colored lines all over my screen vertically. Almost like if you would take the screen and stretch it as much as you could. You can t see anything. So i decide to see if the touchscreen still works and well, it does! I can even receive phone calls.
The phone is rooted, and has a cracked but functional digitizer, no water damage nothing. I have tried turning it off and on, and well in order to take the battery out i would need to open it, which i only want to do if i need to replace the LCD.
So my question is, Is it the LCD that needs to be replaced, or could it be the hardware. Any fixes guys?
(first time on XDA, can't wait to join the community!!)
At&t Htc one mini
(The screen has previous cracks, but this problem occurred way after those were made)
I think that the LCD Panel is damaged, it is not the hardware since your touch screen is working and colours can be visible on the screen. So just change the LCD Panel:thumbup:
