My milestone suddenly displays only a blank screen with blacklight.
Other thing seems well, because i can unlock it, and it can be recognized by USB.
Does flashing a new rom can fix it?
Or it meas it need some cable replace?
I've seen this thread:
http://forum.xda-developers.com/showthread.php?t=970525
Should I change the whole display screen or the cable only?
If is cable problem, which one should be replaced?

Hi,
I was wondering how to recognize that the ribbon-cable is broken? Will the screen be black? For what reason is there the ribbon-cable?
Thanks in advance,
Nobody knows what the flex cable is responsible for?
ive had flex ribbon go crazy on me. What happened was that when I slide the phone open, the screen turns black, but the touchscreen still works, like normal. It's just the screen that turns off.
Ya the screen goes off, but you can still see the backlight on the screen. Its a pain in the ass replacing it yourself.
it's not too bad after taking the phone apart literally 10 times but i still didnt fix the screen, the flex ribbons from ebay suck. They say they're OEM but it's clear that they've been pulled from a used phone. Had to return and order 3 times. Got a new one finally, but it still didn't work. So i just gave up on the phone. Bought HTC Aria lol

it's what sends the "video" signal to the screen from the motherboard on the phone i think.

It's a hardware problem, your flex cable is worn out.
Dear harveydent,
Keybord is working but not showing in display. after opening keypad screen gets stuck & not rotating, & after closing keypad screen shows exactly what I typed on it.

I didn't say your keyboard or screen was broken. I said the flex cable was.
The hardware problem is the cable that connects your keyboard/main unit and lcd screen together (the flex cable). So your keyboard 100% works. Your screen 100% works. But when you slide open the phone, the flex cable stretches. Since it's worn out, some connections break when it stretches the main board can no longer send signals to the screen, so it appears to freeze. But the keyboard (and everything else) still work, so you can still type, only YOU CAN'T SEE IT since screen can't get any signals from the board. When you slide the phone back, the connection is restored and you can see what you typed.

The Lcd is a very simple device, it's either working or not much like a pc monitor. If you properly reconnected it to the mobo it should display an image regardless of whether the digitizer is working or even on the phone. Take the back cover off and recheck the connection. You can also check the connection with a magnifying glass to see if you bent a pin. If you still don't have a visible screen then most likely you damage the lcd when removing the digitizer strap.
tnx

Hello Everyone!
So i'm really stuck over here. I have an international Samsung Galaxy Note N-7000 that is working but with a black screen!
First of all i want to discuss exactly what i have done:
1.i had a problem with the charging port where it works sometimes and most of the times doesn't. So i decided to order a new charging port to replace the existing one.
2. When i received the new charging port i instantly started to dissemble the device (The device was working perfectly before starting replacement)
3. After i removed the old one and installed the new, i turned on the device and it showed only a black screen, then after some time i saw the touch buttons light, but still the screen is black:crying:
4. so i decided to return back the old charging port and this time when i turned on the device it sounded like it's booting and working but still with a black screen. The phone even received call and the touch screen is working but with black screen.
What do you guys think has just happened to my phone? could the new charging port cause any problems with the motherboard?
i'm really stuck and don't wanna go to a service center
I have recorded a video of the problem. Please see it below
since i'm new over here, i'm not allowed to post youtube link.
please head to youtube and type my username and watch the video : nadeaa0a
thank you very much
My younger brother always liked to disassemble things with a hammer wondering after why it wasn't possible to assemble it the other way around.
It took him a few years to understand that real knowledge of things is a clear advantage.
Go to a service center and get help from a professional instead of making it ...

maybe you disconnected the wire you were changing ports ! don't worry and don't freak out just take to any shop and they will check it i don't think the screen is burnt because if it was it would be more expensive ! go to any shop and ask them to change ports and check the screen
for what you described, my best guess would be either you unplugged the lcd and didnt plug it back in properly.... or you damaged the flex for the lcd... the charging flex wouldnt cause the problem... just inspect the lcd flex and plug for damage... if no visible damage plug it in again and try it again... lets hope its just not plugged in right...
I have the same problem
Hi,
I have the same problem. I had never disassembled my phone and the screen slowly turned purple and started blackening out. It was fully functional. This I knew because I connected it to my Windows 7 computer and used Android Commander. I ordered a new screen complete with bezel etc. I have two batteries, the first didn't even charge after I put it in the phone (it had drained totally during the wait for the new screen), the second was partially charged and allowed the screen to boot. It is however behaving like the first screen did before it went black, that is purple. I am sure I have not done anything wrong with the connections. Could it be the batteries? or the adapter flex? I just hope it is not the mainboard. It is not on warranty and we don't have that many honest phone specialists around where I live. I am almost sure others have experienced the same problem and someone on xda knows what the problem is. If you do I would be indebted.

it shows as color black, or nothing (like locked device)? I used to face this problem too with my infuse 4G, but it was because of installing custom rom. Had problem with few rom i installed but nothing happen on my stock one. If your device is just not lighting up(like locked device), then i guess because of ROM, but i'm not sure yet. But if it shows "color black", then i don't know.
THIS IS NOT A SOFTWARE BUG. Its the Screen flex or the ribbon. Disassemble the back part, and take a look at the flex or the ribbon connector of the screen, clean the conector with a tooth cleaner with alcohol and let it dry for a few minutes. Put it back on and mount the back part again. Test it, it should work.
Same thing here: changed the usb port, booted fine, had issues with the sim, turned off took it apart again to check, put it back on and black screen.
Yea having the same issue here, dismantling the usb module and put in new one, power up black screen!! The menu and back button did lights up, and the phone is working too, can hear the booting tone, anyone got any solution for that yet?

You damaged your LCD flex cable or didn't plug it in correctly ..

I have unplugged and replug back few times, same result. Guess most probably i have damaged the flex cable. Replacement part seems too pricy to change, rather buy a new phone.

hi ,
i have a htc one m7 that is not recognized by pc when it is in bootloader mode, however the phone doesn't charge properly when i plug it in the current because the cable moves when it is plugged.
if i use a micro usb with not long exit, it charges well, if i use a cable with big exit, it moves easily and it often doesn't charge.
the second problem is:
the highest part of the screen doesn't recognize the touch, to use that part i have to press strongly and using the entire finger or a big part of it (if i use the extremity of the finger, it doesn't work ), AND the highest point of the screen ( status bar) doesn't work NEVER.
How to fix micro usb?
How to fix screen problem (i think that is a software problem)
i have not original charging cable
i have just tried to do make electro-shocks to the screen but it doesn't work

If your usb port is damaged you can replaced it. Removing the cover of the phone is a little tricky but once done, the usb board is easily replaced.
You can test your touchscreen by lauching the diagnostic menu by dialing *#*#3424#*#* form there you can access the line drawing test. Test your screen and if some inputs are not registered then your digitizer is probably faulty and will need to be replaced.
