[Q] Screen repair gone awry? - Nexus 7 (2013) Q&A

Our daughter dropped my wife's 1st generation nexus 7 and broke the screen. From ebay I bought a new digitizer/screen but when I installed that I accidentally bent and ruined the LCD Screen Flex Ribbon Cable. I bought one of those from ebay. Yesterday I installed the new LCD Screen Flex Ribbon Cable.
The screen now works, sort of.
This is it while booting http://www.unusualgoods.us/tablet1.jpg
This is it at the launcher http://www.unusualgoods.us/tablet2.jpg
Video from yesterday http://www.unusualgoods.us/tablet_video1.mp4
Then this morning I turned the tablet on and it looks like this: http://www.unusualgoods.us/tablet_video2.mp4
Can you tell me what the issue is? None of the other cables seem damaged and I've been very careful handling it.
Any ideas as to what is going on?
Thanks

I had issues getting the links to work, but I fixed it...

All you can do is clean all the contacts with alcohol and reseat them.
Make sure the connections are not loose, if some are you might need to slip a little paper shim in there to put more pressure on the contacts. I had to do this on the charging ribbon of the 2012 or it wouldn't charge. Thin wax paper fixed it.
If that doesn't work maybe the screen was busted to begin with?

While I had posted to the forum, I emailed the ebay seller of the digitizer/screen and let them know what was going on.
After they looked at the pics, they suggested that I take the thing apart, again, clean all the contacts with alcohol and reassemble.
That worked!
Everything is working fine now.
Yay!

Yeah thats what I said. Cool.
I'll add those contacts on the 2012 at least seem to fail after a while. I think it's oxidation of the metal on the ribbon contacts and/or the contacts in the socket.
Whatever. If it gives you problems again you know what to do. Clean it with alcohol.

Is krazy glue conductive or something?

Hey guys,
I tried replacing my DINC digitizer again and everything went smooth until I booted the phone up. The middle of the touch screen doesnt work very well. I checked the cable to see if it was loose multiple times but that didn't work.
So I took the whole thing apart again and looked at it closely and realized the Krazy glue I applied was applied on the side roughly where the problem lies....
Is it possible it is messing with it so that it is detecting a touch there or something? I used krazy glue on there because I thought it would be like plastic.
Or is this just impossible and the digitizer I ordered is defective? It works besides the middle section of the screen.
on the contrary superglue is insulative which could also be the issue since the digitizer needs to be grounded not sure what it is like under the digitizer but is the area it gets glued to kinda metallic if so that could be your issue if not then it could be a bad digitizer i dont think i would have not used superglue i would have used double stick tape or something like that... or hell with how my case i have on mine is designed i would not have used any adhesive just left my case to hold it onto my phone incase it ever got broke again...
Hmm, ah so perhaps it is just not allowing that part of the screen to be sensed.
In any case, I replaced my "new" digitizer with the old one that is slightly cracked for now. I used krazy glue and it worked perfect this time, but then again i was careful with the application.
I will clean off the "new" and try one more time, but I suspect now that the "old" is working so good that it was in fact a defective one.
sorry to thread jack, but since there is discussion already started, I have an slcd dinc, can I directly swap the amoled screen into it? Would you guys happen to know?

it will not work. the board requires different drivers and i think a different power output. (i could be wrong) but its like if you bought a plasma tv and swapped for an lcd panel.
kind of figured that. thanks makes sense.

Dropped in pool, touchscreen unresponsive

I inherited a G2 that had been dropped in a pool. It was dried out with the bag of rice trick and seems to work except for the touch screen.
The previous owner was able to restore to stock and it boots fine, screen looks good, clear picture with no flaws.
However the touch screen is completely unresponsive so I am unable to proceed past the sign up page.
I took it to the lab here at work and hosed it down with isopropyl alcohol, spraying it into every hole and port I could find and then placed it in a desiccant chamber.
My question is, if this procedure doesn't resurrect it, what would you do next? Replace just the digitizer or the whole screen assembly? Can I get the whole screen assembly so I don't have to do the heat gun trick to take it apart?
I have completely torn down a couple of G1s and reassembled them and have replaced a couple iPod batteries and screens so I am fine tearing it apart if need be.
The phone was free to me so I can afford to spend a few bucks on it in my ADD attempts to fix it.
Thanks for any info on what you would try replacing first.
Just as a bit of information for anyone searching. The alcohol seemed to do more damage than good. Now the LCD screen is all dicked up and the touch screen still doesn't work. I am hoping another day in the dryer will help but I think I ruined it.
when using alcohol. weaken it down to about 25%, otherwise it's a bit harsh on stuff
if you are just cleaning a straight circuit board only, like a motherboard, then full strength is fine.
Dilute it with deionized water or what?
sent from XDA app
Yeah you'd want to use deionized, otherwise the ions will mess everything up.
-Nipqer
Should still dry out tho, straight alcohol evaps super quick, just put it in the dessicant chamber again. Id check the ribbon cable from the mobo to the screen first...could be loose or even have some crap on the pins from the chlorine

I tore it down to the frame, pulled the LCD and cleaned in between that and the digitizer with a lens cloth.
I cleaned every connection I could get to with De-Oxit cleaner and a q-tip.
Put it back together and the LCD now has those damn lines down the right hand side like I have seen others complain about.So I guess tonight I will tear it apart again.
I don't recall anyone ever answering what caused the lines down the side of the screen, they weren't there before i tore it apart and cleaned it all up.
Well after fooling around with the phone tonight I am thinking cleaning the LCD screen with a microfiber cloth was a bad idea. Apparently they are way more fragile than I thought.
So now I need to decide if a $65 LCD and digitizer from eBay are worth the cost for a phone that may be completely trashed anyways. I am super curious to see if I can fix it, but dont want to throw money into a pit. I could get a whole G2 phone off eBay for about $200. If I even needed another phone. Which I dont.
Decisions, decisions.

How to replace ribbon cable?

Well, In replacing my spring I broke the flex cable somehow. Kinda irritated at myself, especially since I have my old razr in my pocket, but oh well. I have one ordered on amazon, and my phone is setting on my desk torn apart. Unfortunately, how to replace the flex cable is not immediately obvious to me, as it appears that it's one ginormous piece , and glued down in certain spots.
I figured I'd do some research waiting for my new cable to get here, but I'm finding nothing. The tear down guide that was very helpful in replacing the springs and tearing it down to find the damaged part of the cable is of now help on how to get the cable off!
My first instinct is just to get something flat and pry up the glued parts, assuming that I'll be aligning everything when I get the new cable, but I thought I'd ask first if there is some better solution.
Well, for posterity, that really was all there was to it. There are several easy reference points on the ribbon cable as to how to line up the new one, if you're lucky there will still be some adhesive from the original. The only slightly tricky part is getting the Microphone seated just right, and getting the screen-> mainboard cable through all the slots it has to go through.

[Q] S3 screen/led replacement issue

I recently bought a galaxy s3 off ebay that just needed a glass screen repair. Having done several of these with other models I thought no biggie ill ju st change out the digitizer and have a heck of a deal lol until I started looking into how the phone was made and the screens being fused together like they are. I followed a youtube video and heated the screen with a hairdryer and proceeded to try and carefully tried to remove the outer glass without harming the digitizer or lcd screens fused behind it. Unfortunately when I removed the glass screen the digitizer came with it. I thought id ripped the digitizer's flex cable til I read this phones digitizer doesnt connect that way. It didnt crack the lcd screen in any way tho, so Im pretty sure I can just clean the lcd rly well and make sure all the adhesive and glass is cleaned off and use new 3m adhesive to install a new digitizer then the glass screen over it.
The only thing im questionable about is a thin brown ribbon/wire that was pulled out of its original place iand tore a little while doimg this removal. Some of the adhesive from the factory apparently stuck to it while I was heating the glass and attatched itself to the digitizer somewhat or enough to work its way out and initially tear as I was pulling the glass off. Its not the buttons or the small cable that attatches them but it is right beside them. Can anyone with some experience working on these galaxy 3s please tell me what this hooks up, controls, or what other replacement part I would have to buy that would have this ribbon included in it? Or with this ribbon being the way it is, am I going to have to buy the lcd,digitizer, &glass screen replacement that comes preassembled? I know its not the lcd flex cable amd doesnt go to the digitizer so im at a loss.
Im attatching pics so u will know what im referring to. Thanks for any help its greatly appreciated.
Pics after screen removal.
That's why I paid more and got the LCD+Digitizer. Cost more but made it a million times faster.

Yeah i understand i was just tryin to save a few. I can still do that and not lose but 10 bucks so notjhing hurt if i cant find a solution to this or just make double certain that ribbon being the way it is in the pic isnt going to hurt anything.

I'd go check out this thread and ask some of these guys. A lot of them seem to have attempted repairs already, and many of them have had to troubleshoot different issues. http://forum.xda-developers.com/showthread.php?t=1890708&page=78

My experience fixing Xperia PLAY phones.

In addition to the constant influx of iPods and iPhones friends, family, and coworkers bring me to fix, I've taken apart a few different Xperia PLAY phones more times than I can count, so I thought I'd give a few "pro tips" to people who need to know the ins and outs of it. This isn't a disassembly, assembly, or even a repair guide, it's just the stuff I think those guys missed.
First, don't use a heat gun to loosen the adhesive on the front glass + digitizer. The plastic frame wrinkles and melts readily, particularly right under the face buttons.
Second, make sure you transfer as much as possible when you replace the frame. Replacement frames usually do not include the rubber shroud for the proximity sensor and it will not work right without it. I had one phone that seemingly worked fine until the screen protector peeled off while inserting in a pocket and then no amount of clear tape, screen protectors, or Sharpie-marking would fix it. A salvaged rubber shroud fixed it right up. Some replacement frames have a film-backed adhesive for holding it there and some don't. It probably depends on when they were yanked from the manufacturing line, assuming that they are original parts and not replica parts. You also want to make sure you transfer are the inner dust gasket that goes underneath the frame/glass or else things will be filling up with dust quickly. There is no speaker grill and the foam around it does not stop intrusion. A salvaged frame/glass adhesive is likely to allow dust in unless you didn't have to pick much out of it when swapping (usually glass shards). There are also little metallic grounding foam rectangles crammed in the corners that only one replacement frame I've seen has ever included (was probably salvage though listed as "new"). They probably aren't necessary and I've gone long periods without them, but why wonder if a static charge build up is responsible for your erratic touch screen?
Next, be extremely careful separating the glass from the frame. I've managed to crack good ones even going slowly and leaving gaps filled with picks and pry tools. Heat didn't seem to help much and, as mentioned earlier, is discouraged. Cleaning the screen after man-handling it isn't always easy, but don't avoid touching the back side because you will probably need the area to spread the pressure and avoid a crack. I use a levered "mini suction cup" from Harbor Freight on the top side and as many fingers as spread out as I can on the bottom, but the suction cup is near useless on a cracked screen (even tape-coated). I do suggest covering a shattered screen with tape to hold all the bits together but you are still going to have a hard time cleaning the adhesive up. You can always buy a frame with digitizer pre-installed but I know a lot of you want to buy complete replacement housings instead and it's kind of a waste, but at least you don't need to worry about that adhesive (still: don't forget to transfer the other bits!).
The digitizer parts I've salvaged from phones had higher version numbers than the ones I've seen sold as replacement parts and seemed to be more erratic so I prefer salvaged ones. There can be other problems as well. The flat flex cable from the digitizer is supposed to have an adhesive backing that holds it still where it connects to the tiny cable from the earpiece. Replacements often do not have it, which is yet ANOTHER reason to prefer salvage parts. It may not seem like such a big deal considering that there is a black plastic piece screwed down over it to protect it from getting caught in the mechanism, but the connector does not hold on very well and the phone will not boot if it is slightly out of alignment. If you reassemble it and just get a buzz from the vibration motor with no display and no other sign of booting, check this connection (same thing if the digitizer suddenly stops registering touch). Even a small drop/impact will cause it to happen again, so I recommend securing it with precisely cut tape or hot glue (stay clear of the sliding rails).
Now, keep it clean while you work or you will be staring at that contaminate or thumbprint for a long time. I usually wear fresh latex gloves when working on the glass but it doesn't do much good if you keep transferring oils from the rest of the phone. Wash your hands right before you start and clean the outside of the phone. Before you begin, try just touch a used dish soap dispenser with a damp thumb and run all along to screen except the buttons and earpiece. Do it again with just the damp thumb (dilutes the soap that remained from the first pass) and wipe it with a clean lint-free cloth. Your own clean and dry fingertips/palm should readily absorb any remaining streaks/oils. Be sure to wipe down the rest of the phone too and don't transfer it back to the glass. Once inside I use layer after layer of clear tape to lift gunk from the earpiece (no mesh, remember?). Put on new gloves before you start handling the glass after disassembly, even if you were wearing some for disassembly. To clean the back of the glass I put the adhesive between wax paper while I clean using lint-free cloths, 90+% alcohol, and acetone. For the LCD, use tape to lift most contaminates and resort to alcohol + lint-free cloth if that doesn't work. It doesn't need to be too perfect, especially if scratched from cracked glass. Most imperfections only show when it's off.
Hot glue is great for removing adhesive screw covers without showing pick marks or other signs of tampering but you have to make sure to leave an edge exposed so that you aren't just picking it out of the glue instead. I've been getting mine off cleanly without any tricks like this but it came in handy when I was first disassembling one and there weren't any guides to tell me that there weren't screws under the large silver strip (just covers rivets or injections mold points, IIRC). It's also good for sealing off water sensors, like the one you see through a hole under the battery door. There's another one by the contacts on the battery itself, one by the microphone under the gamepad, and one in the opposite corner under the PS Certified logo. I had an AT&T rep tell me that a brand new phone had a tripped water sensor (LIES!) so I would look for ways to do this with most any new phone.
I can't count how many times I've left the power button out while reassembling. It's not usually that I forgot: It's that it falls out while snapping the back on. I've left the face buttons out a few times too.
My first one had the cable folded wrong after reassembly. It still worked fine for a couple years but did eventually require replacement. Once it folds wrong it'll probably stay that way even after correct reassembly (like mine did). Do not try to attach it to the main PCB using a spudger, butterknife, or whatever to awkwardly push the connector down with everything pulled apart. The only thing you need to do is to slide the cable into the phone's closed position, align the plastic posts on the connector with the corresponding holes on the PCB, and then push down on the PCB until it snaps. I'm sure I tried this first back then but chickened out because the connector didn't snap very easily but that is how you are supposed to do it.
Before I talk about the replacing the slide cable, I want to express my annoyance at all the eBay/YouTube/iFixIt.com people who call it a "flex cable." I don't like the term flex cable because generally ALL cables should be flexible and that doesn't distinguish what it is well enough for people looking for the part. Technically, it's a flat cable or a slide cable, though I wouldn't object to it being called a flex PCB (flex PCBs usually have components other than just connectors like a rigid printed circuit board would). "Flex cable" is silly, redundant, and does not describe anything more specific than just "cable." To complicate matters, there are several actual flex PCBs in this phone to distinguish from when ordering the part. Why did so many people start calling flex PCBs "flex cables" in the first place?! In our case the sliding portion is a *flat* cable, so I can see where "cable" was introduced from, but people say "flex cable" for any flat cable made like a flex PCB these days whether fixed or sliding. At least you know now that you are probably going to have to use the incorrect terminology to find what you want online and sift through many useless results.
*whew*
Now, slide cable replacement is easier than it would seem but intact removal isn't and brand new replacements can be defective. It was a troubleshooting nightmare when I encountered a defective one because I replaced the LCD and glass + digitizer at the same time and suspected/checked everything else first, even taking apart my personal phone multiple times to test parts. The plastic part of the connector on the PCB end must be transferred to the new cable and the old one will not reliably stick back down to it even if you did not contaminate the adhesive. I successfully transferred a cable from a water-damaged phone to my personal phone before fixing up the water-damaged donor phone with a new one, so the adhesive on the salvaged part was weak and I didn't realize how hard it was to remove intact until later. When separating the defective new one there was seemingly no place to pry on one end other than underneath the part where the earpiece/camera connector was located. This broke the side of the connector that holds the locking flap though I was still able to use/lock it. I claimed warranty on the defective part anyway because the connector was not needed for proving the cable was defective (a functional cable works with that connector populated or not). This new part was slightly different from those found originally installed in the phone (different colored plastic connectors and such). The second new one I ordered from elsewhere had double-sided adhesive down the middle, a foil quality control sticker, and the same odd connector colors. I didn't think there was a market for replica parts on this phone but it does seem like more than simple factory revisions. Anyway, removing it involves removing metallic tape then lifting a plate that is still adhered underneath with amber-colored Kapton tape. You can see it from the slide mechanism below. I pinch the plate from above and below with two fingers and lift, gradually peeling the tape which I then fold inside and secure to avoid contaminating the adhesive. The cable has a plastic band across it that fits between fingers on this plate. When secured, this isolates the end with multiple connectors from the movement of the sliding portion, so make sure this is in place when reinstalling. It may be best to avoid removing the adhesive backing paper until after the plate and cable are securely taped back down with both the Kapton and metallic tape while the fingers are holding it in position. If you stick it down first and then secure the plate you may find it slightly too long or short to position inside the plate when securing it all back down. To thread the main connector through the slide board opening it may seem that it will only fit by folding the cable but DON'T! Coil it. Without flattening it, bend the connector 90-degrees over from the cable path and then adjust the angle until you have a coil-shape that you can work through with the connector sideways.
I ordered a "no useable parts" dummy phone just for the heck of it and, other than the Sony Ericsson logo on the fake battery door and maybe the stickers that cover the screws, they really don't have any salvageable parts. You can't swap any buttons, keys, springs, covers, etc into a real phone. The closest would be the face buttons. They will fit in a real phone, but they are too tall and put constant pressure on the PCB switches causing unintended key-presses (especially back and search buttons). The extra height easily protrudes out the top and is not the issue so filing them down vertically won't fix anything. I snipped some excess rubber to more closely match the design of the original buttons but it didn't help. I unscrewed the screw in the corner under the search key and unsnapped the bottom edge of the frame from the back/slide board and they work great until the phone inevitably snaps back together. I'd say they felt better then the original with the extra height (I can't stand how close they are to the screen). It's tolerable with ICS/JB's Navigation Bar (on-screen key functions), but I would rather salvage real buttons or pay too much for the eBay ones ($10-$20; very uncommon part; always sold with crap you probably don't need).
I have yet to find a replacement battery door that includes the rubber trim around the speakers and the foam piece surrounding the rear/noise-canceling microphone. I've ordered a few auctions that show them in the pictures but they always arrive bare. You can transfer them with a razor but it likely won't be perfect. Without them the speaker audio will probably echo around inside the battery compartment and make its way into the mic, though people usually don't notice it. Painting on some Plasti-Dip might do the trick, so try that if it bothers you.
Unlike an iPhone with a million different screws, you don't have to keep track of what goes where and everything is easily accessible. Bare minimum to take it all apart: Some fingernails, a T5 or T6 (pick one) and a PH0, 00, or 000 Phillips (pick one). There don't seem to be any tamper/warranty seals and the only concealed screws are the two obvious ones underneath metallic cover stickers on the display/slide board. There are no screws under tape or labels and no water sensors covering them either. All 6 Phillips screws are the same size but you'll likely want to keep the two with adhesive in their original holes to re-use the covers (adhesive usually remains on the screw instead of the cover). There are only two different Torx screw types but it's obvious what goes where (6 stubby flat ones on the top and bottom, 7 long thin ones around the battery area).
There are bits and bobs taped to and embedded in the rear housing including antenna/RF stuff, some more obvious that others. I've compared and the R800x is very different from the R800at even though the plastic frame looks really similar (R800x has a blocked SIM slot, of course). IMO, any housing swap should be limited to the front frame, the gamepad, and the battery door (only colored parts anyway). If you nicked your chrome, hopefully it was on a button or something that can be swapped (springs are a pain). It may be possible to transfer everything but I wouldn't trust it after all the peeling and picking. The one report I've seen of someone transferring between a GSM/CDMA models seems blissfully unaware of the metal wire behind the volume keys on the CDMA model that isn't there on GSM (at least it's not there on my R800at GSM).
That's all my advice for now. If you are having any trouble, let me know.
Excellent guide, thank you for taking the time to type this up. I think a mod should sticky this.....
Awesome guide! Thanks much for it!
@ozzmanj1 Agree, so more people will notice it.
Thanks for help buddy!!!
As for the case of the digitizer, mine has some parts (lower left) that are not recognizing touch inputs. Will realigning the digitizer cable help? I' d really not want to buy a new one right now as I am quite on a tight budget. Please help. Totally in distress here with my very sickly Play.
So, first I want to say thanks for this post as it's been invaluable in my working on my own XP.
I'm in the process of changing out the LCD and slide cable and am wondering about versions of the phone and compatibility. On Ebay I'm finding lots of parts listed as being for R800i\R800x\R800a. Very few parts are listed for R800at (which is what I have)
In changing out parts (anything hardware related) what parts are interchangeable and what parts are not? Anyone able to help?
Right now I'm looking at LCD screen and slide cable, but in the future I would like to change out the digitizer (I read the other page about having to possibly roll back to a different kernel) and perhaps other inner workings of the phone as well. I would just like to know what I can use from other models of the XP and what are model specific.
Thanks!

Just about everything but the chrome back housing is a simple swap. LCD, slide cable, digitizer, camera/earpiece, face buttons, game pad, slide board, front frame, camera, headphone jack, etc. The only parts tied together for compatability are the motherboard and the chrome back housing and that is because it has all the antennas installed in it. It's probably possible to move all the components but I've never even had to take the speakers out and can't speak to the difficulty or possibility for certain. I'm worried that lifting the adhesive films would damiage the antennas inside. As I mentioned in the OP, there are other little parts to move when you compare the two and note the differences. Good luck!

Have you noticed a difference in an LCD screen with a green cable vs one with an orange cable? I have an orange one in mine, and wasnt sure if its a different part, or just a different batch of screens

I am color blind and never took notice but I switched LCD between R800i, R800x, and R800at and they were all compatible. They have no reason to make anything in that half of the phone different, so they don't.

If only some areas are responsive then I'm pretty sure it's the digitizer. The IC likely encodes the output so that all the raw connections don't need to be extended over the slide cable. IOW, the pins that carry digitizer data probably carry encoded data so that it's fewer pins. This means it would work either all or not at all if the slide cable had anything to do with it.

Thanks for reply... So, do I have to replace the digitizer or just realigning the cable will help?

In my experience, cable alignment has also been an all or nothing issue so you probably need to replace the digitizer. It couldn't hurt to realign the digitizer cable first just in case it can avoid an unnecessary expense. That fixed a Cubot C9+ I worked on Saturday (digitizer not working at all) but not the iPhone 4S I worked on yesterday (bottom row of digitizer not responding).

stuck in safe mode after replace slider cable(flex)
Hi i'm writing here in hopes you can help me, i bought and replaced the "flex cable" and it kinda worked, somehow it can only boot in safe mode and back, home and menu buttons on the front is unresponsive (i can use joypad though) i've tried opening it up again to check for loose connectors and i even tried disconnect the cable to the front buttons but safe mode persists, i tried to flash several official ftf images and a custom rom to see if it helped, but also without any luck.
I hope that you can help me.
Thx for a nice indepth post

If you are booting in safe mode, that "menu" button is always pressed. My guess is faulty/damaged flex cable. You can try your old flex cable and see can you enter flash/fastboot mode (test to see is back and search button is working)

Search button is working as intended (also when booted into safe mode) and i can enter flash mode with back button and flash ftf files, back button is just not functional when booted (only on joypad).
I also figured it had to be the flex cable but i thought i was so carefull when mounting it so i didn't thought i damaged it.
The old flex cable didn't give any picture at all, so can't see if it boots into safe mode with that.

I have received a defective flex cable before so it's possible you have also. In my case it didn't work at all (no picture).

slide flex replacement
hi, its my second time replacing the slide flex cable of my r800i, however this time, my digitizer is unresponsive to the flex i bought, i bought it in the same store where i bought the first one which was perfectly fine before,
my question is does the slide flex cable of xperia play 4G differs to the slide flex cable of the old one xperia play r800i,

They are the same. I have also switched then between a "4G" R800at and a R800x. I have also received bad digitizer flex cables that were new. It really is luck of the draw. A lot of replacement parts on eBay are factory seconds, which may have been removed from the production line for good reason. That's why I always order parts in sets of two for anything I know I will need in the future and I always test both. For example, recently I got two iPhone 4S screens and one had the frame installed upside down. Before that I ordered two replacement iPhone 4 30-pin dock replacements and one had a defective microphone. Before that I ordered two iPod touch 2G digitizer/frame assemblies and one didn't work along the left side.
Here I am identifying a couple bad iPhone displays from a lot:

I didn't own an iPhone so I had to test them all with the phone the first customer provided.
Edit: Oh! And make sure the problem is not with the digitizer connection under the black plastic cover. Mine works it's way loose all the time and needs to be secured with tape. Even when inserted fully straight and locked, I put it together and find it not working or the display black until I take it back apart and reseat it. It will twist slightly and even the slightest angle affects the connection.
