i jus changed the housing on my xda mini now it starts but nothing is on the screen, i hear the sound and bottons light up... ive check connector is in firmly however ive accidently broken the connector lock, does it need the lock in place for it to work...
if not what else can i try
also my flashing status light isnt fashing although fone is on (screen still not on) i get a white flash now and then on screen... and sometimes weird back lines..?
helo????
anyone here?
It is important that the flat cable has a good contact with the connector. I also broke the lock but placed a thin rigid plastic to keep the flat cable pressed down and then some tape on top to keep it in place.
nah didnt fix it, ah well another door stop..
the ribbon myt b broken....i think u'll need to replace display and da touchscreen too
try looking at ribbon cable carefully !

Ummm, I believe he's referring to the long flexible cable on the left side, indicated with the green arrows.
yup! I found it easier to disconnect the red marked connector, than puzzling on the green one.
Do you also have the audio problem???
i'm trying replacing front cover.....
can u explain me how to unclip that connector?
have i to raise it? or pull to the right?
help help :roll:
dood im trying ot figure something out similar to this. i followed that guide to replace my housing, which i think is what ur trying to do. u do have to move the black lock on the left side, lower part, and remove the ribbon connector. i did that, well i pulled the black lock OFF, it says in the tutorial to like flip it up, but i didnt see how that was possible. anyways after i took it off, i cant put teh damn thing back on? its like i have to slide it into all those mini gold pins. i think when i was trying to put the ribbon connector back in i bent a few, so when when i try to turn my fone on, i get a buncha random colors.AHH someone help??
i ve changed and replaced all
so, when u have to remove lcd, is better remove pad connector, the red circled one
don't touch lcd connector!!!
then to remove lcd we have to force a clip on the right.
on the left there is a removable clip, that fixs lcd to cover...
u can try to remove this one first, raising it
but be carefull....!!!

I will have to try this! But where do I get hold of a new cover (the old one is broken) ???
ebay.....
Like the topics states my 8125 will fade the screen every time I slide my keyboard open. It does it about halfway through the slide. Also practically non of the buttons on the front work anymore. I was told the ribbon cable may be loose, so I took it apart. I got all the way until the back of the screen seperates from the screen. I was pulling that apart and it didnt want to come so I just stoped in fear of breaking something. It was almost as if glue was holding a board on. Anyways I looked around as best I could and did not see anything. When I turned it back on it started right up but still fades out when slide open. Its been doing this for some time now and I just got back into the the cell phone thing rather then purchasing a new one. NBD ROM but the problem existed way before changing anything on the phone. Any help would be great. TIA
ttt anyone??
You will have to use a clipper preferably a plastic one to seperate the black back panel of the LCD housing,insert the clipper from the side and then run it along the entire panel till the six(i think) clamps unlock,then gently pry the back panel off taking care not to cut the flexi strip,that should do.It is most unlikely that it is a software issue,85% its a strip problem and 15% maybe because of the LCD.
Any chance you mean the ribbon cable when u say strip?
I have had the cable off and visualy looks ok.
any chance there is a replacement cable that I can purchace somewhere?
So I tried to do this: http://forum.xda-developers.com/showthread.php?t=376035
My screw was loose indeed. In fact is was so loose it fell out before I had opened it completely.
I tightened the screw, closed the cover, turned it on, and... nothing. Only the backlight of the screen, but the screen stays completely BLACK. Nothing. (I know the phone is working though, because if I hold the off button I'll hear the "boink" sound)
I tried this:
- With and without SIM card.
- With and without tightening the screw.
- With and without the power cord.
Mind you I have NEVER had this problem before.
What is going on here? Did I **** something up badly while opening this phone? If I did I am going to be super sad, so please, help me!
Anyone?
I basically have the same fault mate. My vibrator lock screw was loose and it made the phone rattle.
I opened it up and probably either tightened the screw up too much and killed something on the mainboard or 'pinched' the lcd flex ribbon ( rusty gold coloured thing- it plugs into the small white ribbon connector on the MB ) with the opening tool.
Anyway - the phone could take calls , it seems to be working ,although I have no display , and the keypad buttons are all lit up very brightly , what scuppered me was with the constant case opening I eventually managed to break the power microswitch off the MB and I now have to use the reset button to power the phone on.
I don't want to waste money buying a new lcd screen for a phone which might be terminally damaged due to a mainboard fault , anyone narrow these faults down more ?.
shameless bump.
BUMP !!
Im just fixing my LCD on my P3600 and have it in bits,
is the display connector definitely pushed all the way in?
Yeah m8 - AFAIK it is all the way in , I am certain that it is the flex ribbon connector that is broken.
For anyone else interested in this or that has the same problem - there is a program called ' my mobiler ' which can be found in the forum somewhere , using it will tell you all you need to know ;
i.e = if it is the phone itself that's broken , or it's a damaged display.
Hello People,
I've got a little problem with my hd2 ^^
Since several weeks, the plastic from the LED's was pushed inside the device and so the vibration alarm wasn't really silent anymore (since the vibrator is behind the led plastic and it touched it inside).
So now I decided to open the device an push the plastic back in it's place.
Opening the device was really hard because of the massive glue they used^^
But after some minutes I got the electronics out of the body. I cleaned it a little bit up, fixed the plastic an put the device back together.
Starting it, confirmed that the vibration now works silent again, but my screen stays black...
I really don't know what happend there , but I never touched the screen or openend the device more than I had to.
So maybe anyone has an idea?
THanks a lot.
First thing is that i dont understand where you finded "massive glue" if you just opened your phone to place back leds cover/zoom plastic. They dont use glue, only adeshive stick tape. But this is just interesting for me.
Second thing is: are you used some minimalistic bead when you placed back leds cover/zoom plastic? If you didnt, then it can drop again to inside.
If your screen is black then maybe you just acidently touched connector and ribbon cable, where lcd connects to motherboard. You must open your device again and recheck. This connector attached with ribbon cable at lcd must be sealed with yellow tape.
Hello,
sorry a meant adeshive stick tape ^^ I was just hacked off when I wrote this
yes, I put something on the led plastic.
I checked all the connectors and also watched a video where the disassemble the entire phone in order to see where I could have damaged or removed something. But as far as I can see, there is nothing loose or missing. I didn't remove the mainboard; I just took the device out of it's outside cover.
Hmm, i dont have idea whats wrong then.
I opened mine phone not once. Also replaced more 5 HD2 digitizers and lcds. All time dont had this probelm.
Are you sure you dont had static electric on your hands?
yes, I was protected against static electric.
maybe I'm gonna disassemble it totally and see if something else is loose.
Turning it on works, because the vibrator triggers once.
And I just realized that the power led does not work when I'm plugging the device in...strange
So here is my story. I installed a new digitizer for my broken HD2 screen, and ended up creating a crease on the ribbon cable. I managed to also break off half of the lock-in bar (the black bar) on the socket, but it still locks half of the other pins down and in place.
Heres the problem.
I turn on the phone, and the screen lights up but doesn't show me my display. The backlight IS on, but isn't showing the bootup, or anything. I DID manage to get it to show the screen by messing with the cable, but only for a few seconds and then it wouldn't anymore. The phone functions fine, I had a friend send me a text and the phone vibrated, and when I pressed the lock button it locked and unlocked (for my Android ROM). I know it did this because the backlight would turn on and off on the LCD.
Would buying a new LCD fix the problem or does that little black bar on the socket matter? I figured all it did was lock the pins in place so it shouldn't be a big deal..
there is 3 ways out of that.
One put a tape over the back side of the flex. it might work sometimes, but not reliable
Two buy a new socket from ebay and resolder it.
Three hardcorely wire them. It is possible I fixed a broken volume flex before.
the lock does not just hold the cable in place it also pushes it down on the contact face.
You may be able to pack the ribbon on the back to help it fit tighter in the sock & increase pressure to the mating faces, hopefully the rest of cable is serviceable ! extra lock security can be added with tape & ribbon can be reinforced with tape too if helps.
