[Q] Ribbon issue or screen actually croak? - EVO Shift 4G Q&A, Help & Troubleshooting

Ok, so one day I go to "wake-up" my shift and the screen locks up. Only what was showing on it. I could still hit the power button and make it go black, but hit it again and it would range from picture that would "glitch" or freeze even though you could hear the phone still doing whatever I was headed for like opening an app or making a call or what not, to a full on, remember on Willy Wonka when they "beamed that candy bar" across the room close to the end? the pixelization that was shown floating above them would be basically my entire screen. Left alone for like 2 days and powered it up and it worked just fine for about 3 days. Now POOF, black screen. although I can hear my phone doing different stuff, there just isn't anything showing on my screen. And I know it is still recognizing me touching the screen cause I called my brother on accident. So with that being said, Oh, I'm s-off rooted with mikshifted 2.1 so my question to the great gods of phone repair that are on here is, does this sound like a ribbon cable issue or a screen issue? I just don't have the money to start throwing parts at it. Thank you all in advance.

Yes it sounds like a Flex Cable issue. Do you hear a crunching noise? One sure way to tell before spending any money is to take it apart, and look. I've attached a link below of the thread, with a Video of how to do the disassembly. But if you have insurance,one thing to consider before you take anything apart is taking it in to Sprint. If your insured, or you've had your Shift less than a year you should think about it. Yes I would UnRoot before taking it in.

Actually I haven't heard any odd sounds coming from inside the phone and I did pull it apart up to the point where the metal "slider" part comes apart from the screen. Mine doesn't seem to want to release and I'm not sure how much force should be done to accomplish that. and yes, I removed all four of the screws from the back of the screen part of the phone. But as far as I could tell the ribbon cables appear to be in good shape. and unrooting may be a little tricky since I can't see anything on my phone. Anybody other thoughts/input on this?

I threw my phone in a fit of rage.

I was upset, could not handle life anymore. I was at work and just threw my phone with tremendous force into the wall. Made hole in drywall but phone remained in tact. Nothing seemed broken.
I live in a 3G area but not it never displays the 3G icon, infact most of the time it displays the roaming icon. My calls are always getting dropped. The internet on the phone no longer works.
I tried to reset the phone, and did a rom update with a rom I found here. Did update successful but no luck. Then re did a rom update with the latest one from the HTC website.
Same problem persists. How can I know what component is damaged and where can I get the part to fix it?
When I had a HTC tilt, I sat on my phone and broke the screen, was able to get replacement unit and change it myself with ease.
I would like to thank you all in advanced and hope you all have a wonderful day.
Study here how to dismantle the device and what the components are
Dude, some therapy may help....got insurance, do that and get a replacement phone
having taken mine apart, if it looks like it's still in one piece, the thing that jumps immediately to mind is just that your antenna got loose. it's the only thing pretty much with an exposed connector that could pop off. (the display may be able to also, but you'd notice that =)
search for the raphael service manual, only tricky part in getting to the antenna is after you pop the back housing loose on the top 3 sides, you have to pull back the top far/hard enough that you think you're gonna break the usb port to get the housing free of it. Pull it back a bit, unplug that speaker wire, then pull it back some more, needs a gap at the top of about 2 inches to clear the bottom usb port. it'll just click and snap free. i took 30 minutes doing it cuz i thought i was gonna break it.

Just got a used slide, and it's acting wonky.

I picked up one of these off of a lady for $20; it was missing the back cover and battery, but it was in pretty decent cosmetic condition, so I figured I could sell the
parts to break even at worst, haha.
Anyway, I finally got a new battery yesterday, and the phone is acting funny.
So far I've noticed:
1. Microphone doesn't work. Any apps that use the microphone won't work either.
2. No sound whatsoever. Headphones, speaker, back speaker not a squeak.
3. It can't use flash because of the "cold weather." That just sounds silly, haha.
4. Camcorder immediately shuts off when I try to record. (Camera works perfectly though)
5. Won't charge. It will charge for about 20 seconds before it stops charging. The LED will then alternate between orange and green blinks.
6. Won't connect to the computer. This might just be a problem with the drivers, but the computer doesn't even seem to recognize its existence. The phone will "charge" though. (until the LED starts blinking)
7. Will shut off randomly. I usually don't notice when though.
8. Power button is often unresponsive, when waking the device up or even when booting up.
9.Genius Button Useless, although that might just be the microphone.
I first suspected water damage, but what I think is the indicator, the water sticker above the SD card slot, is white. However, I noticed a VOID sticker on the bottom left screw of the battery compartment.
Does anybody have any idea as to what the problem could be? Is it perhaps
software-based? Any suggestions at this juncture would be greatly appreciated.
Cheers.
Hardware fault of some or many sorts.
For connecting to the computer, it may be set to charge only in settings, so then it wouldn't recognize it.
The white water indicator would turn pink or something if wet - so that's good.
The void sticker is good too - it's something HTC puts on a screw to tell if the device has been opened up.
If the void sticker isn't punched, and the water indicator is fine, then i'd suggest calling HTC and seeing about a warranty exhange.
Explain your problems, and that it's not wet and hasn't been taken apart, and they will tell you if the phone can be sent in based on the serial #.
It just might be in warranty period and they'll fix it for you.
Thanks for the suggestion, but I believe the warranty is not transferable. :-(
I think I'm just going to put it up on craigslist/ebay as-is. Seeing as
I paid so little, I'm sure to break even. 8 )
Thank you again!

The HTC warranty is by device.
I needed warranty service on a doubleshot that one of the LED lights died in. I was at least the third owner of the device for sure. I bought it from another developer who bought it secondhand from a person.
HTC fixed it and sent it back to me. All it cost me is shipping to get it there, they fixed the light for free, and sent it back to me at their expense.
The device is guaranteed against defects not your fault for a certain amount of time - doesn't matter who's hands it happens to be in when the problem occurs.
For the money you spent to get it, another couple of dollars in shipping to get a good, working phone, i'd at least call and see were I you.
Is that so? I actually read their warranty policy, and I must have
misunderstood the legal speak, haha.
Thank you again. I'll give them a ring right now..

OT, but it's of interest to me. Is that a panda trueno? or a panda painted s12? Either way, I approve! I own an S12 and I get asked all the time if it's a corolla...
If you can't get it fixed or sell it for any reason, I'd be happy to take it off your hands for more than you paid.
@silverton It's an AE86 yup. I don't actually own one though; they're money pits, haha. Drifter tax. My mother actually owned an S12 when she was pregnant with me. Apparently she was "accidentally" drifting and hit a wall. Must explain why I'm so messed up in the head. 8 )
It's a pity the S12 never got the aftermarket support the S13/S14 did/does. Beautiful car.
@IBTokin I actually managed to sell it on Ebay for nearly $140 yesterday,
but thank you anyway. (-:

[Q] I Screwed Something Up

A friend of mine had a Galaxy S3 Amber with a broken (and blank) screen and wanted her data from it's internal memory that is locked and not in debugged mode. I did a lot of research and found the best, most efficient way was to do a motherboard swap with another gs3. I had a Galaxy S3 Blue. I watched a couple of videos and it seemed rather easy. I gathered the proper tools and was EXTREMELY careful not to break or rip anything (and to my knowledge i did not). When i put her motherboard from the amber one into the blue one and the screen would not come on. My first thoughts were it must be her motherboard that went bad. Well when i went to put my blue gs3 back together (again being very careful this entire time) I'm now having the same issue as she was. Black screen, no back light. The bottom lights DO come on and i feel it vibrate when i get a message. There was also no power on chime...
I know its hard to tell with out looking but any ideas on what could be wrong or what i might have screwed up? i checked all the connections and everything looks perfect. Nothing is bent or connected wrong and I didn't force or break anything.
update: so i found that the touch part of it still works fine. i can hear the ripple unlock as well as all the other sounds and such when i touch around and i can here it opening apps. the only issue lies in the screen itself being blank with no back light what so ever,
First of all remove the battery and attempt to power on, then leave without battery for 1 min, I know this sounds silly but it worked on an old iPhone 3G so anythings worth a shot.
If that doesn't work go back into the S3 and make sure all the data clips are firmly in place and locked down but not twisted in anyway. Also make sure their is no moisture or dust on the ribbons. You may not realise it but even the smallest imperfection with this can cause massive issues down the line.
If all else fails her phone may have broke your screen, I don't know how but it is a possibility
Hope I could help and good luck

so i took it apart again today to double check and clean everything and under inspection i noticed a teeny tiny slit on the edge of the lower, bigger ribbon. i know the smallest bit could be horrid. Any fix and would that cause just the screen to not show? i don't know if that is the led connection but i think it may be.

If theirs a slit I'm affraid that could be it for the screen, like I said even the smallest imperfection can cause massive issues. The slit is probably in the one of the data sections of the ribbon cable which is why data for the screen isn't being carried.
For the fix I don't think their is one unless you can fit a new ribbon on to yout S3's screen
Sorry about the screen
So I took it all apart again. Cleaned ever little thing I could and now it works again. ?

Dropped my P900! Blackout!

I just dropped my P900 and it went completely dark. :crying: There's no mark, not a crack, nothing, but the display is completely dark. The touch buttons on each side of the home button lights up, but the display does not.
Any advice? Or it is Samsung support next?
May the ribbon for the display is disconnected from the circuit board.

Yeah, maybe I should open it myself and have a look. Are there any warranty seals that I will break if I pry it open? I have all the tools necessary, but are there any guides for opening the P900? I wouldn't want to break anything...

This is a video on replacing the battery but it helped me when I re-soldered the battery connection on mine.
https://www.youtube.com/watch?v=VeSG0hHpAG8
I've opened mine a few times and haven't noticed any specific seals but mine was refurbished to start with.
Also I have the proper tools but found a guitar pick was easier to use personally on this tablet.
Starting at the power port to remove the back made it a lot easier for me, its pretty hard to get anything between the back cover and the tablet in other areas.

This was indeed the problem! The connector has some kind of snap lock that had come loose. So easily fixed. Thanks for encouraging me to try to fix it myself. :good:
Glad I helped!
Sorry to hijack your thread but figured my problem might be related.
About 2 weeks ago I charged my tablet and stored it away. The other day I tried to use it and it wouldn't turn on. I tried to charge it but that didn't work either as there isn't even charging activity on the screen. I ordered a replacement battery thinking it might be that, but I was wrong. I still can't make it turn on. Any ideas what it can be? Thanks

I had a similar experience. 3 weeks ago the 1x my SM P-900 is out of its protective case, it falls 2.5 ft off a table. Hits the floor. No visible cracks or breaks. I could hear hear it operating but the screen was black. Took 3 weeks to talk myself up to it but I pried off the back & used a magnifier glass to c.a.r.e.f.u.l.l.y check every ribbon connect. 1 connector's pins were very slightly off alignment. Couldnt find anything else. Put it back together...Yes! Screen works. All seems good. Took the back off again & securely taped over every ribbon connect I could find. Long time intermittent screen flicker issue (when battery was below 40%) also seems to be gone. That has been the best, eye squintin', back hunchin', shallow breathin', micro-screw wrangling, time investment my non-hardware tech self has ever spent. Wooo!

Nexus 5 Audio and Black Screen Issues

Hi everyone, I'm have an issue with my Nexus 5 and hoping someone here can tell me whats going on.
It started off with the sound always cutting out, and I have to press the back part near the "S" logo for it to return.
Eventually the screen would go black but I can clearly see a back light is on. Now not only does the sound cut out, and screen goes blank.
It has become very sluggish to reboot it. I hold the power button until the phone reboots "Google" logo appears and the android animation. Now during this time the phone will be so slow to the point of being crippled out and i have to reboot it again and again until it is normal speed returns. Often it will black out during this time.
I'm just trying to understand what is failing. I tried safe-mode and it still has the issue. I cleared cache, reset the phone everything, nothing appears to fix the issue at all.
edit: I forgot to add, when I'm on YT or listening to music or browsing the web, even though the screen is blank with just the back light on, the sound is still going (when it works). I get text/call notifications still during this time.
My Phone Details.
Nexus 5
Android version, 6.0.1 (MOB30Y)
no ROOT
No replies at all, I guess I may have to garbage the phone. Idk what else to do with this device to fix it.
Please don't throw it away.
You said that pushing at a specific spot fixes the problem (or improves the audio situation). This means that it's a hardware problem. I have disassembled it many times and I know the layout. Behind the 'S' of NEXUS is actually the motherboard cover, and under it are 2 connectors; one for the battery and one for an extra 'board' that is located right underneath the LG logo on your back cover. On that 'board' is your screen connector, and also the speaker rests on there, as well as the primary microphone, 3G and 4G antennas and of course the USB port. The connector for this extra board is actually located a bit to the left on the 'S' (when you look at your phone from the back, it's more below the camera).
Now I have to note this: While using my phone, I have experienced some UI hiccups. At random times (very rarely) everything would just freeze for a few minutes, though music would still play. The power button was useless apart from the hard reset, it was so badly stuck. This was a software problem, although it appeared MOST at one point when my motherboard was faulty. Since I got a new device, it happened again but only once. I'm not sure that this is what you are experiencing. If this is the case, then it's a software fault. Never happened on CM so you can give it a try.
But since it's probably a hardware problem, you can always check it out yourself. Obviously if you have warranty you are covered. Otherwise, you can try disassembling it, at least take the back cover and the motherboard cover off, it's ridiculously easy, there is a disassembly guide from ifixit (I think) online, just be careful not to break the clips of the back cover (xp talking). If you open it, keep away metal things and the first thing you do after you remove the motherboard cover is remove the battery (xp talking again). Obviously turn off the phone properly before you attempt anything. Everything is sensitive in there so be careful. What you should look for is the long connector that connects the extra board that is located at the bottom of the phone with the motherboard. That's what you are pushing so if it's not sitting correctly, then that's your problem.
Plus, everything in there, apart from the motherboard, is cheap and can be found on eBay so don't worry if something is broken (unless it's the motherboard, then no hope ).
I hope I helped.
Firstly thanks for the reply. I did manage to remove the back and get to the connector you were saying. I reseated this and noticed the phone was working much better. I noticed the following still.
When it starts acting slow/crippled pressing this connector fixes the issue. However once the screen goes black with just a backlight this method is rendered useless. Also sometimes when I plug in the wire to charge it will cripple and or go black. So I wondering if the board is shot as you suggested to order a new one, or is it the connector strip ?
Again thank you for the response.
It seems like this board is causing everything. First, check the connector on the motherboard. Make sure that nothing is wrong on the motherboard. Then you can remove the bottom black plastic thing that has the speaker on it and 2 antennas. Then, inspect this board. Check the connector of the display. There is only one big connector on it. This board is glued on the frame of the phone. You can remove it but do it carefully. Do it slowly so that you don't break it. First, remove the antennas extension cables from either this board or the motherboard, and then pull it out.
This board is definately responsible for the black screens and audio issues (unless your display is faulty, check its connector), but I'm not sure about the phone being sluggish. Since this board offers input to the motherboard, I suppose that it could be its fault.
Remove it and inspect everything. Then, if you want, you can order a new one. If you come across D820 and D821 models, I don't think that this part of the phone has anything to do with it so don't worry.
I will take a further look into this for sure, and report back. If you can provide which motherboard is required for my device, so I can also read into this and so that I may order it right-away. Is there any model number or something that indicates which board to order once it is open?
Thanks again!

You don't need to change the motherboard, not to mention it's very expensive and hard to find. What you need to replace is probably the flex cable that goes below the battery. For example this.
This is not model specific, you can use it with all available Nexus 5 models (D820/D821, 16/32GB) so it doesn't matter what device you have.
FYI, if you think that you should replace your motherboard (you probably shouldn't), you need to take into account the storage (16/32GB) and the network differences (D820 or D821, the only difference is about the 4G networking, the american version has some bands enabled and some others disabled, and vice versa)
Okay, I just ordered the replacement flex cable. It is going to take about a month before it arrives from HK , I hope it fixes the issues. I will respond to this post once it is here and installed. Thanks again.

in the meantime, pray it isnĀ“t a motherboard issue, the conector can go bad and lose a few solder joints
I have exactly the same problem... I unmounted motherboard and clean everything but didn't help to much... did you find any solution ??
Siamer no solution just waiting for my delivery of the part. However it is getting worse with the blackscreens and crippled lag.

my is the same. sometimes is working for few hours without any problems and than starting again, on the biggining it was power button problem but not I don't even touch that button (I use vol button to turn on) and sometimes screen getting black (with backlight on) and can't do anything so have to reboot... it's so anoying! Hope that parts will fix it, please let me know if you will find some solution. Today I will open phone and clean all connections etc...
Thanks,

I believe the part may fix it. I noticed if i run my finger along the strip the phone may uncripple itself or just turn black all together. I'm hoping it fixes it. I will report asap but this HK shipping is so slow it will be a month. Also there is no tracking
ATM i'am just trying to becareful with it trying not to trigger the issue. I just did an OTA update using FlashFire (6.0.1 (MOB31E) i wish v.7 will be available for my Nexus 5 ha ha!
Also if the Nexus 7p arrives I may just buy it to replace this Nexus5.

Hi Omega59.
Today I bought air compressed can(name: air dust) and open my nexus 5 as much as I could. I clean everything, every connector, every cable etc. and last few hours is working fine... even power button is working ok. I will let you know in next few hours how it will be, hope will be still ok
Good luck!

[edit]
there is still same problem, working better than before, black screen not showing so often but still showing... I think tomorrow I will order oneplus3... Would be nice wait to see new nexus but how... :/
Yeah I'm not sure when the Nexus 7p will arrive, they not even advertised much. I will assume next year?
OnePlus 3 looks nice, but compared to Galaxy 7 it's a bit better slightly. You should check out comparison charts
Maybe they are making a OnePlus 4 soon.
oneplus 3 already ordered. I don't like samsung. I would say nexus "7p" or "pixel xl" will be launch october as always prabaly 4th of october - leaks saing that... next oneplus will be launch around july next year as I know. the only phone that I was thinking about was oneplus, htc10 or new nexus but can't wait to see nexus...
today by excident I broke screen in my nexus 5, got a little bit angry

You probably don't want to hear this, but if it's getting worse, it's probably because of the pressure you apply to it, you make it worse. Be careful when you apply pressure around the motherboard since it's very sensitive. You REALLY don't want to break the motherboard. So if you find yourself pushing on the motherboard too often, you might want to leave it and wait for the replacement part so you won't ruin it.
Waiting for your news...
My part arrived yesterday. I put it in was pretty easy, however the first attempt i had to redo the top connector bc it was still black screen and no audio. After I disconnected the top connector ran some alcohol over it, re-put the top part things are working okay.
Just a note, the little USB connector (charger slot) seems to be very tight compared to the old one. Maybe bc it's new and not as worn down. But even just to put the wire in, requires more of a push, same with removing it.
I will see how it goes before I can really say that was the issue. I will report after a few days about it.

I don't think N7P will be out this year, they have not advertised anything and we are almost in Oct. Right now they are all rumors.

When I changed my screen and housing it was difficult to slide the USB connector in too. Just make sure that everything is in place, there is a rubber think for the microphone, maybe that's what's in the way. Don't stress the connector too much.
