I just replaced the cracked screen on my Moto X Pure. Now there's no response visually on the screen. It seems to boot up. There's the initial vibration and I can turn on the flashlight by holding power.
I've disassembled and reassembled it several times now without a change in results. The one thing I suspect, but I'm not sure if it matters or not, is this. The socket on the motherboard for the ribbon cable going to the lcd has this black clip that you fold up to remove it. When I first folded it up, it came off. I can't get it back in. The cable seems to stay in fine, and I put a piece of tape over it for safety.
So does that black clip matter, or am I missing anything else obvious?

It seems this is more common than I thought I will post instructions here soon as to how I got it fixed
So for those who try to replace the screen on the motor x pure and damage the black clip holding the LCD flex cable in place...
1.) As soon as the black clip comes off you have damaged the phone. It is only meant to pried up with something thin like fingernails, and using a tool such as a plastic spudger will most likely break the clip.
2.) This mysterious black clip : I don't know what exactly it does but I am pretty sure it connects some of thing metal connectors, and if it is broken some of the connectors are most likely also broken, NOT GOOD.
3.) If you get no response from the screen when booting up but get a vibration, then the connectors most likely are the issue.
Right off the bat I'll say you need to find a specialized repair shop which does micro soldering. I took mine to many places first labeled as "phone repair stores" but they were unable to do anything, and the only place was a company which did micro soldering.
In my case, the repair shop had to order the part in to solder on, and they had to order from China, so I do not know how accessible the connectors are.
I hope this helps and be sure to hit the thanks button if it does help, feel free to send me a PM as well if anyone has any questions regarding this topic
Update : here are a couple of images of what this might look like

I wanted to change the touch screen on my QTEK 2020 and I bought a new one a few days ago. I opened tha PDA, but when I tried to pull the touch screen off, I damaged a slim orange cable on the back of the screen. Specifically, I pulled a black sticker and it took along the two cables that were on the circuit on the screen. I don't care for the touch screen's cable, but for the one of the screen. I have scratched the insulation on the cable and I have a question. If I just put over the circuit the nakes cable and glue it a little belower, would it make connection? Or have I to solder it? And How am I going to soldier a cable like this that's naked from the side that I don't see when I put it in place, without even melting and damaging for good the screen or the cable itself? I have some pics, too for you to see and understand what's going on. Please help me, as I am a young man with prospect and I want to learn things like this and do stuff more than the usual.
OK, I couldn't wait for advice so I soldered both cables. The screen turns on and it needs to be aligned. I tap the screen, the touch screen works, but when I finish the alignment, it starts from the beginning, the cross in the center. It asks to be aligned constantly. I haven't assembled the PDA, I have it like the pictre below. Is this the problem it doesn't start, or do I have to put the touch screen somehow differently? I have it centered and tried to align tapping a little upper, lower, left, and right from the cross, but nothing.
Please HELP!!!
OK, no worries! I fixed it! It took me all evening, but I'm completely satisfied. Solder this, solder that, make a bridge because a connection was damaged with all the scratching, but it worked!
cong. dominator happy that you have finally fixed it :wink:
Thanks Kbantikos my boy! And here's the bench and the heat tool I used! That's the only that I have. No doubt it took me 4 and a half hours to complete.
Congratulations! I'm not kidding, saw a lot of "homework" results, in some cases, display was damaged beyond repair.
You get the working display, so you are lucky .
Thank you, my friend! I didn't believe my eyes when it booted! It still works fine, even if it fell off my hands one time!
my touch screen is really quite dull / lacks brightness even when on the high setting
i've aquired an XDAII that isn't working but i know its screen was bright when it was working
my question is: what do i need to be looking out for / be carefull of when i replace the screen
what would you do differently?
thanks
Larry
You'll definitely have to look for that orange cable that's not of the touch screen. on the back side of the screen there should be a black sticker. When you try to pull it over, it takes the cables, too. So pull it from the side of the touch screen's cable only. You are gonna need to solder the new touch screen for sure, just placing it won't work. Scratch the side of the cable that's going to be placed on the circuit on the back of the screen so that the metal contact on both (touch screen's cable, circuit) is naked. Put solder on the circuit's contacts. Then put the cable on top of the circuit, but a little lower. Now, burn the solder holding the cable steady and connect that way all four contacts. I hope I was of a little help, observe my pictures and good luck!
Just about to try this myself.
Touch screen bought from - http://stores.ebay.de/hitechhk. Arrived within 1 week.
Removing the black tape on the back of the screen, even very carefully, pulled off both the connections for the touch screen and another connector (the back light I think)
In hindsight would recommend only removing the tape around the touch screen connector.
As soon as I find a small enough tip, will resolder everything.
Detominator7, how did you change your digitizer? cause i need to replace mine too, but the seller is talking about soldering it. i already open my pda and all i can see is there is only plastic cable. how do you solder on plastic?
Your touch screen might have a cable that plugs into a hole and does not require soldering. You know, like the fans we use on PC.

good job! I have the same problem and so i got a new touch screen but i cannot get over the calibration thing same as your problem before can you give me some tips as to what to do im just about to give up and get a new lcd.Only thing stopping me is the price of a new lcd.
What kinda adhesive do they use on the back of the screen
I'm talking about the clear glue type adhesive on the back of the screen in order to hold the ribbon in place
here's a pic of what I'm talking abouthttp://blog-imgs-3.fc2.com/i/n/u/inuchanbt/CHT9000_dismantle12.jpg
The gold/copper ribbon glued to the screen
had to replace my brothers screen about 3 times and now its barely stickin
it's a kinda like double tape. u can find in office stores
I hard reseted my O2 XDA II & I had surprised the screen aligning can't be passed.
Can somebody help me with ROM Flash or maybe some hardware tricky?
I use WM5 from C_Shekar.
PM me if anyone replies this message.
Thanks, Berns.
anyone know how/where to get an xda mini II repaired? i'm in italy, but i can careless where it has to go. I'm at the point where i would rather just sell the device for it's workable parts (if there are any)...Today the screen has done a myraid of interesting things...anywhere from blank to thousands of vertical lines....ugh...
ohh yeah...warranty is void....or is time to just move on?
ok...no answers so i thought i would add some images ...anyone seen this before?
Mate i had a similar **** up a while back ...I did a HR and it worked fine..for me it was caused by a Overclocking software [Dnt want to Name it ]
If this dnt work try the Batt out and back in trick
Call ur Local service Center...
mine looks exactly teh same! but it happened after i tried to replace my housing, i screwed up the little gold prongs where the ribbon connector from the lcd plugs in...****! any ideas on how to fix? im the us so service center isnt really an option, and id ont want to send it off.
hi i had the same problem with my magicians, after i changed the housing. i found the problem with my device was that i had not plugged the screen back in properly. all i did was to ensure that it was pushed in properly before i clipped it back in
Menappi -
I had the exact same issue. I reopened the casing WITHOUT disconnecting any cables. I flipped the screen's ribbon black lock up, while maintaining pressure on the ribbon so that it does not pop out. When the black lock lifted, the preasure of my finger moved the ribbon further in . I pushed the black lock down, reassembled the device and ... PRESTO!! the screen works perfectly... and chumps on the bard advised to buy a new screen!!
Good luck
Hi All,
seems, you have problem somewhere in display connector. However, sometimes I see similar picture on physically broken displays, let's imagine, you were careful ad didn't use a hammer during housing replacement.
There are two possibilities: at first - try to remove and re-insert display cable (I hope, you know. how brown lock works). If there is no success - try again. At second - some wire on flat cable may be damaged. Sometimes, good technician with soldering iron can fix it, sometimes not. And if you used force, removing cable, board connector may be damaged too. However, only the experienced man can find it easily.
So, try to carefuly re-insert display cable. Try several times. If you are unsuccessful, you, for sure, need an experienced technician to fix your device.
I hope, you are not enough mad to send device for repair to Russia
Okay, so I had this G1 for about a month now, works fine, rooting was a blast, but I wanted to get rid of the cracked digitizer glass. So the part comes in the mail... I read and followed the take-apart tutorials to the letter, install it, put it back together, and what's this???
The screen is dark with no display, I slide out the keyboard and I get a display but no back-lighting. I wait for the thing to get to the home screen and I am not getting any touch-screen action. Any ideas? It is safe to assume the digitizer may be dead but what's the deal with the darkness?
Prior to installing the screen I had the back-light issues and I thought "maybe one of the flex cables are loose" but now I am dead in the water. Any info anyone would have about this would be helpful
Thanks

That sounds like the right thought. Clearly, something isn't connected properly.
As i see, there are three variants (from good to bad):
1.) You`ve connected some cable badly, or, for example, you`ve didn`t put down the black blocking panel on some of connectors where it is. As for me, i`ve additionally put some scotch upon any connector i was attaching - it works.
2.) Some cable went bad due to inaccurate handling. When i was doing the same thing (replacing G1 digitizer) - it was stated in manual, tha flex cables, especialy black ones, connecting mainboard with LCD&touch block - can be easily torn. You should examine then carefully - electrical tester would be a nice idea.
3.) You`ve spoiled some chip on the board with static electricity on your fingers. It is really rare - but really bad variant.
Hehe turns out that the flex cable was already fried before working on it, thanks to a great friend I received a new flex cable and was incredibly surgical putting all those cables back in, but I did it. Back up and running @ 100% muahahaha!
So how do I cook for this device?
Hello
I can't charge my LG G2 D802, so I ordered a charging flex cablefrom ebay.
After replaced, the phone charges well, but the screen is almost unresponsive.
And it's very interesting, because if I replace to the old one, everything is the same, almost unresponsive screen, not like before disassembly...
Any idea what to do?
Connectors and everything looks fine, but I can't believe touch screen stop working after disassembly.
Please help if You could...
Thank You!
You disassembled the phone? If you didn't put all the components back in place as it comes from factory and taped, then there could be grounding issues. There is a set of transistors next to the lcd connector and above the charging port, make sure it's touching the golden pad on bottom and is taped.
Or else it's a bad cable, bad grounding somehow, moisture issues etc etc.
I think You're right.
The set of transistors may not connecting well.
Can I use processor pasta to glue it back?
Or just some simple tape from above?
-----------------------------------------------------------
So I cleaned it with alcohol and the original glue getting stronger, so I put it back to the right place and put some tape on it.
But still the same.
Do I have to put tape on the cables above the battery?
How could I find where is the bad grounding?

No i don't recommend to put thermal paste therez if it conductive it can short nearby components and can also get messy, it is only for using on chips. I suggest you use double sided tape, but do it strategically so that it leaves a small portion open for the golden pad to make contact. And after that you put nonconductive tape on top of that. Make sure the metal part of the white cable nearby is not touching this area, or you can also put tape between them. I suggest to put tape on the lcd connector as well.
Whenever this problem arises, and if you have trouble to fix it, an easy way is to disconnect and reconnect the battery after a few seconds, should work ok.
You can also purchase a new one like this, look for your device model - https://m.ebay.com/itm/183023879505

Seems like the set of transistors well connected now and I put tapes on it and on the screen connector as well.
And I reconnected the battery too, but nothing happened.
It's the same as before.
And if I replace the charging port flex cable to the old one, it's the same too, but before disassembly it works, but the problem was I cannot charge the phone.
Any other idea what should I do to fix it?
I cannot choose D802 on the link You gave me...
Anyway I think this one and the old one is fine if it's about the touch screen, have to be something another...

Hello,
When i was trying to place a new screen on my moto x style i forgot a screw and part of the motherboard fell off (picture), any motherboard experts know what this component is and if the motherboard is still 'repairable'?
(The screen is working but i can't seem to boot up the phone, it also can charge)
Thanks in advance

To be accurate, it's not that the part fell off, but it pulled away from the motherboard. What you had pull away is simply a screw hole for keeping the frame attached to the motherboard. The good news is that it's apparently not connected to anything. You could use a small amount of high strength epoxy to reattach the screw hole to the board.
As for your inability to turn the device on, check your button cable and make sure you have that seated properly. The screw hole pulling from the motherboard isn't the source of that issue.

Oh, that makes sense, i've already tried replacing the button ribbon cable (with a new cable) so it isn't the button cable, i have no clue why it's not working. Anyway thanks for the info.
