New Problem :
Please see post #10.
Old Problem ( solved ) :
Hello,
I had told my problem in this thread but got no response so had to create a new thread to see if someone helps.
My problem ( I mean my fuze's ) is :
Firstly my fuze was having few scratches and the digitizer was broken lil in the edge/corner so I thought to replace its digitizer.
Brought new digitizer ( 2 months back ), disassembled the device and while removing the flex cable, broked its buttons strip ( volume and ptt button ) and while removing/separating lcd from digitizer, I destroyed both!
So next I brought new lcd and flex cable. Stupid seller sent touch pro flex cable instead of fuze. Had it return it and the fuze flex cable is on way now.
In the meanwhile, I tried to install new lcd+digitizer and damaged flex cable but I'm getting only backlight and no display/image. Sometimes I get thin RGB/rainbow vertical lines and once or twice I got the display/image too. As the adhesive conductive tapes/fabric/stickers got weaker I brought new copper conductive tape ( Like this ) and sticked them but still I'm not getting display/image and only backlight.
I'm very fedup and stressed about this although spent 100$ and Due to this, I able to cook roms and I'm out of xda dev since 2 - 3 months :'(
If someone could help, you will be greatly appreciated. Please please help!
I don't have money to buy new device either and have no mobile phones to play with since from fuze is dead.
Thanks a lot in advance....
Best Regards
I replaced the lcd in my phone and had the same problem. I later discovered that I didn't have the ribbon connector in all the way. I hope this helps.
you need a working flex cable...the same thing happened with but on a nokia n95...the blacklight was comin but no display changing the flex helped

Hi
I had the same problem last night (wasted 3 hours). Just replaced my LCD as well, broke digitizer was a problem. Anyway, after taking a phone a part 3 time figure out what the problem was.. The two ribbon cables have to touch (mostly likely a ground).. The LCD one and log flex one.. I will try to find you a picture..
Now I have a different problem, can't align the screen properly. The right side on screen is way off.. What a mess..

I tried everything but didn't got it working. Though I have doubt on original flex cable that I broken while removing.
I have trouble with getting new flex cable on ebay. First the seller sent wrong flex cable ( TP's which it doesn't fit for fuze ), 2nd time the flex cable lost in shipment and 3rd the seller didn't had stock to resend so refunded.
Now I have brought the flex cable from different seller and its about 14 days and not yet received.
When I tried touch pro flex cable I didn't get the display but only backlight but once or twice I saw the display so I think it was something wrong in my connect. However I didn't had much time to test the device using touch pro flex cable because I had to return it!
This is what I'm playing with my device since 4+ months. Mostly waiting waiting waiting......
Thanks...
Best Regards
I can see that ribbon hold contact.

The ribbon aka conductive tape/sticker I have is no longer usable. Its adhesive gum is too weak and no longer sticks. I have searched lot to find such conductive tape/sticker and found copper conductive tape/sticker. Using it now.
@sadik007 and all
I got the flex cable today and after testing, I' getting same problem. No display but only backlight. I see some minor rainbow lines which haven't saw before but as said, I checked the grounding and everything seems correct.
Fed up of this and desired to sell it as parts or repairable...
Best Regards
Finally my fuze is back alive.
Got Correct Flex cable and new LCD. Now its working perfectly.
However, a minor problem if anyone can help.
The brightness setting of LCD in settings -> System -> Power -> Backlight seems to work only till 40% and then after it doesn't increase the brightness of the lcd.
In auto mode, its same. I think the brightness is working only upto 40% and then it doesn't increase.
Cannot understand whats but I guess its because the seller gave me diamond lcd instead of touch pro/fuze. As I can see, diamond lcd doesn't have variable resistor and my friend say its a brightness setting.
But the hardware setting should be atleast full and we could decrease through software.
Can body help me how to solve this problem? I guess its not possible.
P.s the brightness from 0% to 40% is not bad to use but may have trouble in sunlight.
Thanks a lot for all your helps...
Best Regards
p.s My problem is something like this but the backlight is working fine.
Edit;
I don't think my FUZE stops giving troubles. New problem started since last night and today.
As the backlight was lil dim on sun light, I went to try Lumos app. Didn't saw any difference, just sucked at 40%
Today when I booted my fuze morning, it started to do some malfunction in LED lights ( LCD backlight and front penal keypad backlight light ). Backlight of keypad is no longer working when pressed its button but buttons work fine. And also if I slide out the hw keyboard, the home button backlight turns ON. and also the d pad circular light and back button backlight.
Cannot under stand what the hell is going on. If I get any SMS or EMail, d pad circular light rounds fine but if I connect USB to charge, d pad circular light doesn't work.
I removed the Lumos app, softrebooted, hardrebooted, and reflashed but still same problem.
Any idea?
I guess I'm stupid or the device is fooling me.
Thanks again...
Best Regards

Same problem.
Backlight setting changes only 1-4 interval and does not brighten 5 and more.
I had heard that problem one sells his tp which's lcd replaced.
Options:
1) while replacing, flex can be damaged. I do change screens for 6 years and hard to beleive it.
2) keypad membrance can be damaged while replacemnt of lcd. More harder than option 1.
3) eBay sellers sells fake lcd screen.
I handle over 5 diamond and tp screen far away and still keep some cracked ones. They all different from each other. Somehow there must be different versions of these lcd's.
By the way I also tried a diaond lcd and it gives same error.
first 4 step is ok but no more 5 to 10 steps working.
Problem was solved:
HTC P3700 LCD and P4600-T7272-touch Pro LCD screens are different.
here is the differences illustrated on photos:
@sokomind
nice find. Yeah I do see the changes from touch pro lcd and diamond lcd. touch pro lcd has 10 led levels and diamond has only 5.
Part No :
Diamond LCD with 5 LED brightness levels : 60H00130-00M
Touch Pro LCD with 10 LED brightness levels : 60H00129-00M
29 is what we need for Touch Pro but in ebay sellers don't know the difference of these lcds. They ship what ever stock they have. I had requested to send Touch Pro LCD and also said the part no but they sent the diamond LCD.
Damaged 3 times in shipping and when I got the working one, it was diamond lcd.
Anyways, now I'm using the device has a 3g data card and 3g router. Working g8.
Thanks...
Best Regards
I still have the problem as #"10 cracing.
I got a diamond lcd and then ordered a touch pro lcd.
Yes TP LCD is brighter but it is still working 4/10 on brightness. And then I see that my flex cable has lost one of the way. I try to fix it but it still give me 4/10. I do not know if it fixs a new flex. I do not want to spend $20 more.
Have you spare TP flex not fuze?

I recently got a touch pro of a friend with a damaged screen that didn't turn on but the touch screen was responsive. Apparently he sat on it and the screen broke.
I then acquired it and replaced the LCD screen and i turned it on but all it shows is a blank black screen with the backlight on. I was tapping while it booted up and it was making that beep noise so i know the touch screen works. What do i do now.

if the lcd is damaged and you only replaced the digitizer then that wont solve the problem, the digitizer just sits ontop of the lcd and recognizes your touches, hence why it mite know that your touching the screen but the screen is still blank

I replaced the LCD along with the digitalizer. Tats what i meant.
Sounds like either the new screen is inop on fit (fraid you need another to test, then send the first back as faulty), or the fault is not the LCD itself.
Possibily its the wrong screen, or its not installed correctly, or you damaged either the screen or the controller when installing.
I'm afraid you dont have many options - take it apart & rebuild to ensure correct parts & fitment, spend £££ on alternative parts to see whats broken (or serious £££ on test equipment!), send it off for repair or give up!
I'd go for option 1 first
If your friend sat on it hard enough to break the screen, i'd be looking for any damage / cracking to the boards / ribon cable mounts and be looking very carefully at the mountings of any IC chips. Incedently, when (s)he sat on it, did the screen work at all? and was it 100% working before they did?
Okay thanks for the replies. I just bought a flex cable where the slider thing is because the old one looked a bit old and flexed out and on inspection of the old screen i found a tiny rip on the screen's flex cable too. I wait for my cable and see if it works and if it doesn't then i'll sent the screen back as faulty and get a new one and if that doesn't work then I'll give up and sell it again
hi
sorry to wake up an old thread.
so what's your solution/conclusion?
is it the flex, or the LCD that broke?
i have the same problem right now.
thanks

Hey,
I accidently dropped my phone in water a couple of days ago. The backlight doesnt work. Under a really bright light i can see the lock screen and it still functions. Is it possible to replace just the backlight? or what should i do? I dont believe this would be covered from motorola and I live in canada got the phone shipped from the states.
Any advice would be appreciated.
Thanks,
James
I'm guessing you might need a new screen/display. Perhaps do a search and find a repair place you can ship it and get an estimate? I know HTC offers such repairs dirctly (ship the phone, they call you with an estimate). I'd bet Moto does as well if you're not comfortable with 3rd party repair.

I have the same problem right now except mine was not dropped in water. In a bright light I can see the lockscreen and also could see the emergency dialer tonight but the keyboard was not reacting on certain buttons either. One screen said to unlock enter your gmail account info,I tried to enter my name and the period symbol(.) was not working for me. I'm thinking maybe the LCD screen needs replaced or the ribbon cable,IDK. Any help is GREATLY appreciated.
Edit: Essentially I finally got logged into the phone and the keys were working fine,the screen was still dim so I turned the brightness all the way up and turned off automatic backlight. I replaced the LCD screen and digitizer and now the phone is not starting for me. I'm about to replace the Flex Ribbon Cable inside the phone and see if this corrects the problem. Right now i cant get the phone to start up so I'm thinking the ribbon cable is disconnected somewhere because it hooks to the motherboard and the LCD or the motherboard is fried. IDK,I'll let everybody know what happens with this project.

What happen to letting everyone know? Were you ever able to get it going? Was it the flex cable? How did you get the LCD working.
Replaced the flex ribbon cable and it still didnt help anything. Guess its just the phone. I trashed the phone a while ago anyways and am currently running a rooted Droid 4
Sent from my DROID4 using xda premium
So, a few weeks ago my phone started acting weird. When I would open the keyboard, my screen would turn off. It did this for a few days, then it got worse. I couldn't even use my keyboard. Then, my screen would randomly start flickering... and now it just won't come on at all. The phone comes on, I can see the notification light blinking, but the screen won't come on at all.
I'm going to buy a replacement part for it, but I'm not sure if it's the digitizer or lcd screen. Anyone know which one it would be?
...at first...no digitizer, no display.
open the phone and check flex cable connection - maybe is poor connected.
If this not help then check flex cable.

yeah i was thinking it could be the flex cable, but i haven't played with it much yet. maybe i will tonight and see if my flex cable is disconnected/bad... but i couldn't find any replacement flex cables (without a lcd display or digitizer) anywhere.
IF it was the lcd, what would the symptoms be?
check flex connection and let me know

yessss no problem
i've always wondered if there is actually some way to buy flex cables replacements in case they break... so far, i have only found the whole frontal assembly which costs quite a lot and that includes the flex cables, turning what would have been a couple $ repair into a very expensive (and probably not worth) one
i got an old working photon q that i was keeping myself for spares in case...
if you want a part then PM me. x

i'm confused how to release replace my flex cable
Is there a tutorial how to replace the flex cable with front camera as selled by parts4repair? Or is it really foolproof?
It seems to me like I'm facing the same issues as described in the start post, only in an earlier stage of degeneration of the flex cable:
1. Suppose, the Photon Q is turned on and in operation. When sliding out the keyboard only some millimeters, the screen goes black. If I press the power button at this stage (keyboard slid out some millimeters, screen black), the phone seems to crash and reboots.
2. Suppose again, the Photon Q is turned on and in operation. This time I slide out the keyboard all the way (no matter how fast). The screen goes black. Pressing the power button at this stage doesn't show any effect. Only after pressing it a second time, the Photon Q is awake again, showing me the lock screen - apparently no crash and no reboot!
3. Suppose, the Photon Q is turned on and in operation. I turn the screen off by pressing the power button once, then I wait for some seconds and slide out the keyboard all the way. When I turn on the screen this time by pressing the power button, the lock screen appears as expected and everything is working fine.
All these scenarios also work the other way round, i.e. you assume the keyboard is already slid out all the way and you perform the slide-in movement. Also, this is not a software issue as it behaves analogously during reboot or in recovery mode. Furthermore, I opened my phone. The flex cable was connected properly and I couldn't see any damage to the flex cable. So it seems to be an internal loose connection of the flex cable.
Hello. I got this Z3 with a broken screen, when I got it it had only black backlight, no image, but the LCD cable on the bottom was cut, so I thought that was why it had no image.
So I replaced the screen with a new one, but the issue remains, no image, only black backlight.
Tried restoring the software with Sony PC companion, updated to latest version, but it didn't help.
The phone boots fine, touch works, I can select options and sometimes I even get audio readouts of what is on the screen, just no image.
Is this a dead motherboard or something else? Because I went through a couple of new screens, none worked, so I'm out of the ideas.
I haven't encountered a case like this before, the screen either works or doesn't, the fact that the touch works and I have backlight puzzles me. No backlight or no touch issues are a common case to me, but this is a new one.
Can someone help here?
Thnx

It's a faulty LCD connector on the motherboard, in my case. Not the connector itself but the small jumper just above it, it gives power to the LCD, it was broken off.
I had it resoldered. Works fine now.

The three square fuses on the bootom of the picture, it's similar in Z3, in my phone one of those was broken off.
Hi guys. I have almost the same problem but inverted. My display and touch is working but i dont have backlight. I can see the screen only if i put light on it.
Maybe u guys have a faulty digitizer responsible for image faulty(no image), better for send repair, flashing new stock firmware will not help
I tried with new digitizer, no luck. Tried jumping the fuse with no luck. Don't know what to try anymore.

Put the motherboard in the oven and bake it for a few minutes, it resold everything, if that's the problem, it will fix it.

The constant rebooting could be a power button issue.
Have you tried a factory reset in fastboot mode?

actually i have no lcd or frame on my phone, as i am waiting for a replacement,because it fell on ground and lcd broke but here's what i did to make it work:
just put some transparent tape over the red area, try to cover everything, except screw stocks , and only then place the flex cable.
this worked perfectly before i broke my phone. in 3 day's i'll get a replacement lcd, so i'll be able to make some photos of how it's supposed to be.
If it won't work be really careful while removing the tape, so you wont wrip the lcd conenctor.
