So I ordered a new LCD and digitizer from new harbor via amazon.
I took the phone apart, installed the new array, and powered it on, and the screen is great (maybe even brighter than the last one) but it just has zero touch input.
The last screen worked fine, but the LCD was broken. I could have it acknowledge touches so I dont think that the motherboard or anything else is broken, so I wonder what may have went wrong.
Should I take this mofo apart again and see if I have a loose connection? Maybe the ribbon cable is not connected right?
Probably the past is DOA?
Help please! thanks.

Is this somewhere in the service menu? I can boot into its custom menu by holding down volume and power... Not sure if there's more to it.
It's rooted s-off so I get menus to get into recovery or fast boot etc

Scratch that. Just re read your post. "Zero touch input". It's an option in the rom.
There are a few threads/posts where people have replaced the screen, either here or the dhd forum. Check what they had to say. I have absolutely no experience in that. Perhaps it's a cable as you said, but before doing that, I would research on it first. You may end up like me with 9 screws left over after taking apart my ps3 three times (screwing it up even more).

Removing and taking it apart isn't a problem. There are only eight screws.
This isn't fun... To be certain.

Did you ever get this taken care of?
Just replaced mine. LCD intact. Touch no longer working. They aren't kidding: this phone isn't fun to work on. It's a *****. I've repaired a half dozen iPhones. This makes that stuff seem rudimentary.

I've had my inspire apart several times. Other than removing the Flash/GPS, and separating the LCD from the frame its quite simple. If you want a pain try a slide phone.

Understand your pain because just recently I had to change my entire screen for my Inspire 4G. I assume that you did everything correctly but here is the video that helped me on youtube:
HTC INSPIRE Screen Repair and LCD / DIGI REPLACEMENT from phonedoctors
If you did everything correctly it could just mean that you prob got a faulty part
Hi all. I'm having an issue with a 727R. I replaced a broken screen and now can't get the screen to stay on. Its a non rooted, factory 2.3.5 phone. When I turn it on, the sghi-727r screen pops up for several seconds and then dissappears, phone vibrates once, notification sounds appear shortly and all touch functions appear to work (by sound and haptic feedback). For all intents and purposes, this phone is on and working perfectly...if you're blind lol. I know the replacement screen works because it works perfectly if I go into download (odin) mode. I've been searching threads and haven't been able to come up with a solution, as most of the other blank screens are from bad flashes. Keep in mind that I am also testing this with the casing removed as it is a repair for a friend (if that makes any difference). Any help or ideas would be greatly appreciated and thanks in advance.
Is the brightness maybe turned ALL the way down? When it finishes booting shine a flashlite on the screen and tell me if u can see text, icons etc...
I'll do that as soon as I get home this afternoon. I could only hope that's all it is, but i'm a little skeptical that I could be so lucky. forgot to mention that I have also odin flashed the stock rom back on just in case of software corruption. I would also think that I would get full boot logo's during the boot sequence, but hey!....its definately worth a shot! I've seen stranger things . Thanks for the quick response.

No worries, keep us informed. I didn't even bother to ask because I just assumed someone at your level who can change a screen would intuitively know to Odin stock... I was right :good:

So you had display for start of boot and d/l mode? If so, then I'll go no farther until I get another replacement screen.:crying:. Come to think of it, when plugged in and off, the charge symbol shows up for a second and its discoloured (almost like its made of vertical lines that are pinks and grays). You may have just saved me a lot of time. I was leaning toward trying to adb error logs in hopes of finding something. Other than that it was going to be a reflow on the gpu since the phone did do a leap of faith from 6 ft up....and lost lol.

No dice icenight. Tried out of hope but its completely black. I was really hoping for maybe a fault that could be fixed with a flash.....whoa is me....looks like I may be sending screen back and getting another. I cant send it out for another day so if anyone has any other ideas, or wishes to guinea pig this unit until one comes in, feel free to chime in. And thanks for the responses so far!

Hi guys,
my DS did some strange stuff lately. It began with the screen staying black when I woke it up (hardware buttons did turn on and touchscreen also worked). I thought it was a software issue, because after a few on and offs the screen usually worked again. Also, this never happened when the phone was charging.
But a few days ago the screen never turned back on again, even when charging. I got a new battery but still no change. It won't even turn on when booting or when going to fastboot/ hboot.
Does anyone have an idea what is broken? I think my best guess is to have a look at these other screen replacement threads, but I wanted to ask first because the screen seemed to have gradually become broken, which confuses me. I didn't think something like that was even possible. Also, I can't return it since I bought it used and in Germany (DS is USA exclusive).
Thanks for help
Most certainly hardware as it is black when in bootloader and ROM. Best guess is the LCD but could also be the main flex the likelyhood of any thin else is fairly small.
Do read up on the screen replacement threads as this phone is one pain in the ass, you also need to be aware of what LCD to buy as there were different ones and they are not compatible.

Thanks for the tips. Screen might be still ok since it went out gradually, could be a defective contact since it also went on and off randomly. But I guess there is no way to only replace this contact, too complicated to find out... I will see.
Yeah, I had a look at these threads already, thank you
I had a program that I moved to the sd card that would cause the screen not to come on and would have to do a battery pull. When I moved the app back to the phone, the problem stopped.
(Walgreens app)
It has happened again since, so it may be another app I have to track down. Or I may be looking at faulty screen trouble too.
Sent from my MyTouch 4G Slide using Tapatalk 2
even if an app on sd were the cause of this it certainly couldnt make the screen blackout while in recovery and bootloader mode. to the best of my knowledge it has to be a hardware fault if screen wont turn on in bootloader... but well ive been proven wrong in the past
Well since I had problems with the screen turning off before when it did work in recovery, there might be a connection to daswerk's case. However I kept all my apps on the internal SSD and do remember checking it. Also, my screen turned back on sooner or later or when I played around with the keyboard.
However later it was off even in recovery mode. I did disassemble my DS lately (and broke my screen like seemingly everyone else hehe) and am now waiting for my new LCD screen to arrive in Germany from the states haha. Shipping costs were higher than LCD costs, d'oh! Thanks again demkantor, you've been helping me indirectly with your posts in the other threads as well
So guys, screen arrived, reassembled my phone, switched it on aaand... black screen.
Graphic chip or motherboard may be broken. I'm thinking about a loose connection because screen turned off once in a while before it never got back on. I found a user by coincidence here on xda who reported the same problem.
Any ideas are greatly appreciated. Don't want to forsake my dearly loved DS :'(
Next most likely would be main flex cable

Are there other possibilities as well? I'm thinking about getting a whole replacement set so I can try everything shipping costs are high since I live in germany hmmf
btw, digitizer/ touchscreen doesn't seem to work either, is this another sign that main flex cable is the prolem?
There are always more possiblities I was just letting you know what I would replace next as the most likley cause.
Having multiple phones to exchange parts is a good idea and really about the only way to test different components
And yes have no digitizer working can be a sign of a bad flex as well

Is the screen visually physically broken or just no image ?
If just no image, there is a high likelihood that the LCD Display cable has come out of the board / screen
Its a common issue when they get dropped or knocked as the cable is partially wrapped around the battery, which shifts and pulls out the cable
Very easy to push back in
Here is a teardown video showing how to dismantle the TF101

This video shows the cable you're looking for

Tried it and it didn't work didn't take it apart further so if anyone has any other suggestions I don't really need the screen to work as I'm mainly gonna use it for streaming to my tv but I would like to get jb on it not a big deal just tinkering now lol
Sent from my SGH-I317 using xda premium
afaik the only way you can flash ROMs without entering recovery / having a screen is via NVFlash or genuine ASUS updates being put on the root of the SDCard, but there are only ICS ROMs that are NVFlashable
Unless you can convince a dev to build you a one off NVFlash JB ROM
--
Seems strange that the screen would fail without being physically damaged
Does the screen backlight come on or is it 100% black as if powered off ?
I would still be tempted to investigate further into cables coming loose, IMO well worth completely dismantling it and rebuilding it the one time, just to be absolutely sure it is actually broken
The back light still works but all I can see is vertical lines where the image should be, I'll try totally dismantling I was thinking the same thing just got lazy lol but the wife is going on vacation so I'll definitely try it tomorrow night, and I was afraid that was the case for the rom thing as all I could find was ics but thanks for all your help I will update

Hmm lines on the screen, I thought it was just black, that could be a lose cable, but also could be a cracked screen, I used to repair laptops a few years back and broken screens would sometimes show lines even though you couldn't see the crack
Worth a shot though, and if there is no wife for a while, good timing to play with gadgets
There have been quite a few folks who have had similar screen issues who have benefitted from taking the back cover off and reseating the video connector. Seeing lines could be indicative of a slightly loose connection and not necessarily a broken screen

Cheap fix
I may be the only one that gets this lucky, but I was having a lot of trouble with my usb port being seen by computer. It got to the point that I had to get the phone ad cable just right to charge. I decided last night I had to do something or replace phone. I powered down phone and squirted lighter fluid in the usb port,then took a toothpick and piece of rag and cleaned best I could. Phone is working great now. All of my cables are charging and being seen by computer.
I was at point of replacing phone anyway,so don't try if your not prepared for failure, but good luck and let me know if you have success with this.

And so it happens.
I hooked up my phone and made a file transfer and then...usb stopped functioning.
I tried a whole bunch of stuff, thinking it was just the pc or the driver recognition..but no go. Even after pc wipe and reinstall OS and drivers. No luck.
The sad part is that I was on a rooted 2.3.6 but after a wipe, the stock sammy recovery replaced the cwm recovery.
No usb means no return.
I did try to use alcohol, wiped and scrubbed. I even opened the phone and try a few cleanings. Even disassembled
No luck.

Ya know..come to think of it, I think that resembles water and chlorine dried up on a metallic surface of PCB board doesn't it? I'm still trying to figure out how that happened.
@deathblade:
I had on old solder iron I bought from Big Lots years ago for about $4-$5.
I filed the point down using a whetstone. You can use a file or just the rough surface like cement, brick, clay or just the bottom of a ceramic plate.
The one Zen suggested looks good.
Here is another inexpensive source:
http://www.harborfreight.com/30-watt-lightweight-soldering-iron-69060.html
Just take your time.
If you never done it before, open an old electronic part and practice.
I'm not an expert at this. I feel comfortable in sacrifice my phone for parts but I don't like the idea of messing up someone else's phone.
It's better if someone else messes up their phone though.
I did buy 10 of the usbs charging port. If it works and you guys need one, hit me up, I mail you one at cost and stamp. (~$1.70ea + stamp)

yeah. I recalled that. but you need that board and the riff box and others. not feasible for one infuse unless you are planning a side line business of jtagging infuses.
for the cost of that setup, you could buy 2 working infuses or a later phone model

I had severed the 7 pins with an exacto blade.
de-soldered the points
cleaned up the points
socketed in the new port
seems to fit
soldered in the new port.
slightly sloppy but seated well
re-assembled.
no reading or charge
I think it's due to poor new pin/old pin contacts.
prolly could have used better equipments or techniques
I left the new port in place and prolly will just send it to the mobiletech guys
i have 9 brand new ports available.
Just an update guys...
I soldered the new port on. My first attempt. Kinda sloppy actually. I wasn't able to clean off the old materials very well as I had concern about over heating the board. I think having the correct materials, solders, flux, magnifiers, and heat shield cloth and such may help. My attempt did not work. I suspect I was not able to get the 7pins to touch or connect properly.
I sent mine to mobiletechvideo without the port.
It's about 10 days turn around. It came back working. I was not expecting it to boot up and was ready to flash it back to stock myself but it came back with the leaked GB KK4 firmware installed. Kinda odd I guess as most of the return to stock on XDA were either UCKE3, UCKJ4 or UCLB3.
Although when I have the Infuse on the data cord at an angle that stress the connection, the computer reports the device as unknown. I suspect it is not as good as factory ship but good enough for me to restore the phone to function.
I'll have to keep an eye on the connection for now.
Conclusion: it can be done..but better success if you have the proper equipment for micro welding.
Glad to hear it's working
