Hi everyone,
yesterday my htc falled on the ground. since this happend, the display is Black, but the background LED light if the phone is on. I hope, that just the display connector is unpluged, therefore I downloaded the service manual, but the opening fails. Does anybody ever open his Raphael. And the problem is I dont have this flat plastik white thing shown on the pictures in the manuel. If anybody can help me, thanks
I got the t-mobile version mda vario 4.

hope this helps!
thank you that worked but I couldn't get to the display connector without having a star-screwdriver....
And not sure that it is just a loose cable.
What can it be?? Display is not damaged, backlight works, just the panel doesent changes the pixel.
Anybody had this issue one time before?
thanks

Hello There,
I'm from Portugal and i bought 1 MDA Compact on TMobile. I Unlocked it with XDAdev v 1.6 and it works great in my network. After i done a stupid thing. I flash it with a wrong rom and it "Dead" . To recover i Reflash with a Jam_10605_169_10500 ship and it return to live. Now power on and let me calibrate stylus but when try to enter in the main screen apear a White Screen. I can manage and view all with Sync, but nothing more apear into Handset.Only a white screen. Can you help with this please.
Dear Marco,
Usually that's a sign that your LCD is broken. I've got one extra magician with exactly that same problem. Everything works but not the LCD, which seems to be dead. To confirm it, i've tested this "broken" magician with a good LCD and i can see everything...
I guess that you have done something extra besides only upgrading the ROM...
I had phone with dead motherboard, I bought another one with broken screen but it conflicts with my screen - It is white. Display from new p535 also looks bit different from my old display, but connection is same. Is there a solution for my problem or I have to buy another display?
Where have you buy?
I am a pro of PPC LCD?
I've got the same problem- I bought P535 with broken screen and it didn't display anything and was white, so i repalced the screen with a compatible and completely new one. It turns on, the phone function is working, i.e. i can call on the pda when there is a sim card inserted and yet the screen is still white.
What can be the problem?
connectors seem to be OK ... I also tried soft reset but still of no avail.
any help is appreciated
edit:
is it possible that the screen is only lit up because the ribbon connecting lcd to the mainboard is of differnt color than the original?
the seller from whom I have bought the LCD with touchscreen wrote that it will work fine with asus p535 and p525 but in mine the ribbon was golden and in the one that he sent me ribbon is black and the model is different -originial was tdo028steb2 and the new one is td028steb1, although I found on the Internet that tdo028steb1 should work with p535..
I'm losing my nerves and patience... ;/
can anyone please help me with this?
i have the same problem. Thanks a lot for your answer
same problem but on HTC Legend
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.

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?
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
Same problem....

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.
Could ju point me a bit closer whitch one it was?Did you get no image at all or something like the one on my picture?https://drive.google.com/open?id=0Bym65RPW_fIpeXlkX2NTYUw5SVk This is how mine looks like around the lcd connector.https://drive.google.com/open?id=0Bym65RPW_fIpTXZpWTFKby1Ua3c

No image at all, only black backlight ant the touch was responding.
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.
For more infos and temperature / time, google it

Pleas Helpppp Anyone with the genius mind??????

Hello all,
I have tried looking for a solution for this problem, but none can be applied to my case, so here it is: I have a UMi Iron Pro, and after the screen cracked earlier this year, I ordered a new LCD + Digitizer. I have now replaced the screen, but when I turn it on, it only emits black light. The phone does charge (according to the notification light) and my laptop recognizes a USB device when I connect it. However, the phone is quite useless now...
So, does anyone know what could have caused this problem? I am happy with any input.
Thanks in advance, Dennis
