So on my Nexus 5, the backlight started going off randomly... tapping phone would bring it back..
Then eventually it went out and i had to bend/flex the phone and it would keep working a while..
I contacted support then, but one time i bent it a little to get it on and the frame (plastic outer edge cracked), doh.. Now, of course, they will not give me a warranty repair because the device is physically damaged. So i tried a new screen, no dice. Now i have two good screens and a phone that still wont work unless i bend the crap out of it. Anyone else see this problem? Worth trying to replace motherboard? or should i just sell parts (new screen i bought, old screen, battery, etc) and buy a whole new phone... There is one specific point where i can bend it and backlight comes on, but i cant find a short or loose connection anywhere. I have had the thing COMPLETELY apart and back together multiple times. I should mention, it works totally fine when backlight is off, just no backlight so i can only see it in super bright direct illumination.
Any ideas???
Take it to a mobile phone repair shop.

Fixed for now! Woohoo! Based on the position of where i had to flex it, i tried a little gap filler... a folded piece of paper, between the SIM slot and the back frame. With everything screwed back together, it just puts a little pressure on that area of the main board.
Now the only problem is the screen i bought is defective (lines all up and down it) so now i have to disassemble again to put the old one back in.... oh joy, now to return it through ebay... I'm sure that will work well. Either way, phone working again! FYI, this phone is REALLLY easy to take apart and put back together.
EDIT: F.. snapped the end off one of the little antenna cables (the black one, on the right when looking at the uncovered back of the phone) when redoing the screen. Anyone know what that is for? WiFi and cell data signals seem ok.. Looks like a diversity antenna for something, because of all the others at the tope. Maybe google will have an answer.

Check Bluetooth/try calling/using data just to be sure.
Do not discuss something on how to make fool of insurance company or even an warranty, It's not allowed here. Thanks

Well im having rogers ship me a new phone (i only got the phone last friday, so not even a week yet) because the phone is unable to detect any sim cards. I dont know what the exact cause of the problem is but im pretty sure it has something to do with me opening the back case and pressing it back in too hard. Or maybe i short circuited the metal of the sim card holder some how when i was doing rom reboots
In all honesty, the design of the back panel is completely stupid and really cheap. The plastic is super flimsy and garbage. Plus the way you have to snap it back into the phone requires some pressure that could easily damage the phone.
Just be careful when you guys are touching around that simcard metal area. Any static electric shock could potentially cause you to end up with a expensive brick.
Ummm why do you need to put pressure on the middle area of the phone?
Whenever I place the back cover back on, I just start from the bottom of the phone and make sure that its in and then go around the phone clockwise and clip in the rest of the phone edges and thats it. Never have to touch the centre of the phone.

This is what I also do when I need to put the cover back on.
I didn't press the middle when I was putting back the rear panel but I think I might have touched that metal sim bracket and maybe that's what caused it to short circuit.
Just becarful when handling with no rear panel. Also while charging the phone and trying to get a gps lock, the area behind and around the simcard gets really hot. My stats widget says 53c and that also might have caused this weird short circuit... I I don't know
You're doing it wrong.
Post deleted, wrong thread.

Static shock is a potential problem with any electronic device.
I don't think the cover had anything to do with it.
Mine is on and off all the time, 5-10 times a day at times when I'm testing different things. Never had a problem like this.
Actually the back is pretty durable for the amount of times I've torn it off in a hissy fit...plus I love the texture. I'm always afraid I'm going to snap it in half but it can take alot of bending. It's amazingly flexible for plastic. But you never press the middle...slide your finger along the sides only till it all snaps in.
+1 for that. I slide my fingers on the sides to push it in

No offense but why is this not locked? How can you brick your phone cause you take the back off the WRONG way?

I wouldn't call what he did "bricking". Bricking is usually caused by an upgrade gone wrong. He supposedly did damage to his hardware by pushing on the center too hard....and it's worth knowing about.

The back panel is seriously the only thing I dislike about this phone -_-
Why did it have to downgrade from the Captivates nice hard back panel!
in retrospect i think i might have bricked the phone by doing a bad flash instead of it being a physical problem. Im pretty sure somewhere along the way i must have deleted the EFS files when i was trying to get rid of the root and restoring it back to original firmware. I did some research and the problems im having with the no carrier/no imei/ is related to EFS being deleted.
I just dont know how to get it back now.
Also if i send the phone in for warranty and they find out that the EFS is deleted, would they consider that my fault? Luckily the replacement phone i got torched itself (screen burnt out in like 1 hour) so they are replacing that for the galaxy S II but i still have to send the original one back.
you obviously did something wrong. I've had some crazy electronics hooked up to my SIM and other parts of my device. I keep wires soldered onto the mainboard which lead out of the device for direct communication with the processor. I have never run into a single problem.
You did something stupid with your sim card. It does not damage easily even when you're playing with the ciruits all the time. I know this because I do play with the circuits all the time.

Maybe to save some money, and to reduce phone weight.
Last night I dropped my TF 700 about 5 feet onto concrete floor.
It was working fine right after the drop, but the screen panel ('Gorilla Glass') was popped out a bit and one
corner of the frame was severely dented. But the worst part is that I thought I could fix it on my own.
So I disassembled my TF 700 following the 'TF 700 Teardown Tutorial.' I was able to fix the dented aluminium backplate
(I ripped off the warranty seal during this process though).
After this I reassembled the tablet and everything seemed fine at this point.
However, when I tried to turn it on, the screen display wouldn't turn on. I know that the tablet is still functioning because
when I connect it to my PC, I can see all the files saved. But the screen is completely dead.
I'm pretty sure that this is because I accidently bent some cable component that connects the LCD panel to the mainboard
(the flat cable thing that is made up of copper fibers). Upon closer examination, it looks like the bent cable is preventing some parts from
connecting to each other (please see the picture attached). I really need this tablet and I'm here to ask you what I could do to fix this.
Where should I go and how much do I have to pay to replace/fix the bent cable? Or even better, where can I get the new back-plate? Cuz mine now looks terrible..
Desperately waiting for some advice...

Ouch! Tough break. Unless you have insurance, shed a few tears, bury it quietly in the backyard behind the garage, and buy a new one.

If you do not have an extensive warranty, you'll probably lose about as much money repairing this unit as when you'd buy a new one (it sounds pretty bad, judging from your story). It might be better to bite the bullet, as BTrack proposed.
Hard for me to see what happened by the pics.
Someone had post sometime back that they were parting out their broken Infinity.
Maybe the search can turn up the thread.
Glad I've had a folio around mine.
Banged it a few times being careless.
I feel for ya...hope you can find a fix.
Ouch, unless yo have insurance I think you may be out of luck. I know Asus will fix tablets with " costumer induced damage", but they charge for parts and labor. And it looks like it would cost more to fix than buying a new tablet.

.Just an off the wall idea, you might try sending a PM to someone who has bricked their device and see if they want to sell it. You might be able to pick up the case and connector that way
I had a drop onto tile with my first prime.
My AMEX covered the cost but they made me send it to Asus (even after getting an estimate) instead of just refunding the money like they had on some previous items. When mine dropped it was just the front glass that cracked all the way across, as well as the aluminum body being deformed. The touchscreen was working, screen worked, device was fully functional. The final repair + shipping came to around $378, and that was still a functional (though sharp, pointy and ugly) device when it got to them. If you bought it on a credit card you should check to see if they have any kind of accidental coverage. Good luck
Well thanx a lot guys..
Thank you for all your help.
I guess I just have to buy new one then..:crying:

Why don't you try taking it apart like you initially did, buy a bricked one and try to fix it?
You could sell it to me so I don't have to disassemble a fully working one to play with hardware
I had dropped mine off a table onto a concrete as well. About the distance too. Hit right in the corner of the power button. The glass held up well. The metal bent up and plastic completely cracked through. I was able to squeeze it back together, but was still bent up. It still was functional.
I was did an a-hole move. Since I did it a week after receiving from Amazon, I told them it came damaged, but packaging was fine. They exchanged and not a problem.
You could try exchanging it from where you got it. Another option, there are aftermarket warranty services that you may be to use if you got recent enough. Some allow you to get purchase within thirty days of purchase.
Although, my guess, you probably past that time. I would suggest trying to fix it again. At this point, you have nothing to loose.
Send it back ta Asus for an estimate to repair. Ya never know, you might get off with a cheap fix.....worth a try.
I'm bummed for ya though.

How do you diagnose what to replace on your tablet? Is it possible with the tf700t?
Here is the scenario- I travel a lot and kind of pack my backpack tight and I think the extra pressure on the tablet has screwed the right side.. I turned on show touches in developer tools and a touch comes and goes from the right mid side (sometimes it moves) .
I was able tdeal with this for a while but now after my last travel it's made it almost impossible to use the tab. My tablet it is out of warranty, unlocked and rooted so don't know if I could sent it to Asus for repair.
My question is, is it my touchscreen I need to replace or is it another component? Currently I I hold the tablet and apply pressure on the right side (back) I can make the touch go and come. If I turn the screen off it will remove the touch for a bit. if the touch won't go away I try to apply pressure to the back in various spots to it goes away
My understanding is if you can see what's on the screen the display panel is good. If there are touch problems then you MIGHT need a new digitizer. It could also be that in bumping it around and what not that the ribbon cable connecting the digitizer has come loose. Heat sometimes seems to be involved in this happening too. There are a couple threads here about these issues, fixing them and how to go about replacing the digitizer yourself and where people have bought them. It's not a feat for the faint of heart but it can be done at home.

Thanks I'll check it out didn't know if it was the touch screen or digitizer. I'm typing on it right now so seems like touch is just fine.
I suppose I'll open it up and see if a cable is loose. But do you think Asus would accept it for repairs? It's unlocked and rooted.
They woud gladly accept it for repairs... but they would charge you a bundle. Your warranty is void since you unlocked.

Touch screen/digitzer I believe are one in the same.
Sure Asus will fix it. In/out of warranty. But as mentioned, they'll charge you big bucks. My guess to replace the digitizer would be about 300USD. MIGHT be a little less.
If you open it somewhere inside, can't recall position, there is a service switch you should turn off 1st, before you do anything else. That might keep you from frying some component should a short develop somehow. Just remember to turn it back on last before you finish inside.
I recall reading that the ribbon cable is held in place by either glue or double sided tape and the heat aids in its becoming loose and can be part of the problem with the digitizer getting all crazy.
BTW Anyone can feel free to correct or add to this....
So, I dropped my Moto X Style a couple of weeks ago, the screen broke and the touch stopped working from the top-half of the display.
Decided to change the screen myself, so i bought a new one and watched a couple of videos with instructions.
Everything was fine, till I reassembled the phone.
I tried to turn it on and got the initial vibration, and if i wait enough i can hear the receiving notification ring, but the screen dont turn on and neither the touch works.
Someone went through the same problem? Am I forgetting something?
did you check to make sure all ribbon cables were in place? I just changed mine yesterday and had no problems, except for not realizing the new screen and front frame didnt come with the speaker grill/plastic things or the front flash/led, luckily i didnt throw those out. im stoked i was 2 for 2 yesterday, successfully did a glass only repair on an s4 (dont see what all the fuss is about....) and the moto. id say take it apart again and make sure you got all the connections in place, otherwise check and see if they will offer a replacement for a bunk screen, if not, they shipped me 2 replacement screens (i think due to user error on my girlfriends end, she bought it, and is prone to that kinda thing ) i could probably sell you for what it cost, unless she wants to send it back for whatever reason

I need to fix my XT1575 as well and am looking to buy a screen. Is it just the glass or the whole display? Also, how much does it cost?
Whole display +front frame (realized after I put mine in that it doesn't include the speaker grills or front Led, so save those!) and I'll have to double check but I believe 90~ish (whatever the going rate is in eBay) noticed on the one I installed that you can see one of the lights through the screen in one spot at a certain angle with white screen, 8ll post updates if anything goes bad though to avoid seller, but as of now still working great /light new
I just got done replacing my screen as well. Bought it off eBay for about $80.
I am posting to second Skinnykinney's warning about the front LED. Don't forget to pry it out of the old frame!!! I am going to have to take mine back apart because I just noticed the new frame didn't include it.
And another thing, don't take the silver screw out when you take all 20 of the t4 screws out of the back! The silver screw holds in the power and volume buttons and you might loose the teeny little springs if you remove that screw. You can leave the silver screw in when disassembling.
There are a couple of videos on YouTube about disassembling the Pure, but neither of them mention those two important things. All in all its pretty easy though.
Yeah I didn't even know about the tiny microscopic springs until I watched a different video that showed them, so those are also long gone.. Don't really notice it though luckily still functions just fine, just annoying thatci have that big old hole where that led went, never could find the little sucker, thankfully I have no reason to use the front camera ever just gotta tape it up to keep lint/other pocket debris out of it
Can you show me the videos ?
I don't have them offhand but it was one of the few videos they have on Facebook, and there's one on xda

The phone itself is really easy to breakdown though I used a hairdryer to loosen back adhesive just be careful of the ribbon cables near power button the rest is pretty straight forward and the back should just stick back on without needing to use new adhesive

I cracked my phone screen yesterday after getting it repaired. ($60) bucks gone. I figured I'd fix it myself. I actually did it. I noticed it wasn't getting any signal at ALL, I always get 4 bars inside my room and I remembered that I had moved the RF cable with the screwdriver that was magnetized. I don't know if that might have been the problem. Well after I put it all back together I fudged the screen and I opened it back up and I discovered this after I took out the battery. Screenshots follow
http://i.imgur.com/OMAE9Yw.jpg
http://i.imgur.com/V5sGFpI.jpg
What isnt noticeable is that the metal clip furthest to the bottom that helps hold the RF cable is gone, I couldn't get it back into it. Does that matter? If so I need to get a complete assembly then.
Also note that the LCD screen is not cracked. But it looks like it is bleeding.
What I want to know is 4 things.
1. Is it fixable?
If not, I'll sell on Ebay for parts.
If it is. then do I
2. I want to know what could cause the LCD damage the way it is, is it from pressing to hard underneath it?
3. Do I need a new RF cable?
4. Is there a name for the flex piece that is in the pictures? I know it is tied to the power, volume and camera buttons. If their is a part, I'll take it to a professional this time.
I found the name of the piece, Its called a motherboard Flex cable.
But Im really wanting to know If I need a new RF cable because of touching the end piece with a magnetized screwdriver fizzed it out.
Thank you ahead of time.
I guess you'll need to replace your whole lcd screen along with the digitizer. You could easily get it on EBay.
About your antenna cable. I think it's damaged and that's the reason your not receiving any reception.
Few months back i replaced my lcd screen cause of some touch issue i think i accidentally damaged the antenna cable and now i dont receive reception in my room or college classroom. I have to move out to get reception.
