I dropped my phone and shattered the screen. afterwards, the phone started behaving weird, the screen was purple with yellow static, but it still worked. So I bought a replacement screen and replaced it, but after the replacement, the same behaviour persisted. I googled it and found out that it might be the usb flex cable, so I replaced that. After the replacement it worked fine for about half an hour, then it just went black. Now when I turn it on, the backlight turns on, but nothing is being displayed. If I press down on the flex cable connector I get that purple yellowish screen that I had before, but as soon as I lift my finger, it goes black. Did I damage the connector on the motherboard or did I break the flex cable when replacing it?
Perhaps
not very helpful, but thanks anyways
I soaked all the components except the screen in alcohol for an hour and let them to dry, but it's still the same. By the way, I tried the old flex cable as well and it behaves the same.

the solution is to resolder the connector of that flex cable on the nexus 5 mainboard. Use a heatgun and heat it up until the solder smelts, you can add some flux before that. That should fix it

Hi,
My phone has a problem, i hope someone can help me, it started about a month ago,
When i slide the keyboard the screen would freeze, the image would freeze or sometimes it would become like this:
http://www.esato.com/board/img.php?id=140762 ( this is not my phone its just a pic i found)
This problem would be solved it i gently slide the keyboard back in, the screen would be back to normal, sometimes i had to slide it out and it
alot of time to make it work.
Well, today i woke up, with the screen of my phone all messed up ( like in the picture), i slide it out and in alot of times but no luck.
I turned my phone off, when i turned it on, the screen doesnt lighted up or showed something, the phone just vibrates, i took off the battery and tried again but no luck.
I read somewhere that i could be the flex cable, so i ordered one, but its gonna take some time to arrive.
Anyone had this problem before that can help me?
I didn't encounter such problems on MT4GS yet. But being a slider phone enthusiast I could 100% say it's a flex cable thing since I encountered that problem more than a dozen times already on other phones(nokia).

I would strongly recommend that you get a cable with the speaker already soldered in place....
+1 to that, get as much pre assembled as possible, this is about the most pain in the butt phone I've ever had the pleasure to disassemble. Read the last few posts here!

Yup. That one has the speaker, it's the black bar at the top with the silver sticker.

thanks for this bit of advice.
Disassembling the front of the phone is a pain. I'm a fan of spending $40 on ebay on a broken phone (where the screen still works just fine) and swapping out the fronts. That will get you a new flex cable as well. Otherwise, you risk having to get a new flex cable *and* a new LCD.
Agreed. First time disassembling front I was scared not to OVERheat phone internals. I ripped in half trackpad ribbon, damaged lcd back cover and got a lot of problems from it.
Then I bought broken phone with good front, but dead LCD. Second time I just lost it, I heated phone so hard that I got burns on my fingers, but it was worth it, LCD glue came off soo nice.
So better to overheat, then underheat when disassembling front LCD.
So, a few weeks ago my phone started acting weird. When I would open the keyboard, my screen would turn off. It did this for a few days, then it got worse. I couldn't even use my keyboard. Then, my screen would randomly start flickering... and now it just won't come on at all. The phone comes on, I can see the notification light blinking, but the screen won't come on at all.
I'm going to buy a replacement part for it, but I'm not sure if it's the digitizer or lcd screen. Anyone know which one it would be?
...at first...no digitizer, no display.
open the phone and check flex cable connection - maybe is poor connected.
If this not help then check flex cable.

yeah i was thinking it could be the flex cable, but i haven't played with it much yet. maybe i will tonight and see if my flex cable is disconnected/bad... but i couldn't find any replacement flex cables (without a lcd display or digitizer) anywhere.
IF it was the lcd, what would the symptoms be?
check flex connection and let me know
Was you photon disassembled?

flex cable
Corn,
Can i post photo of my flex cable, to let know what you think if its broken or not,
the black coating of the cable were ripped off caused by the heat and friction to the metal clip and body,
often i play game application and while xt897 condition is heat i slide it to reply an incomming message,
and im about also to but the parts from etradesupply.com is it recommended or is there another supplier you recommend for xt897 flex slide cable, this damage also happen to my xt862 the previous year.

yessss no problem
i've always wondered if there is actually some way to buy flex cables replacements in case they break... so far, i have only found the whole frontal assembly which costs quite a lot and that includes the flex cables, turning what would have been a couple $ repair into a very expensive (and probably not worth) one
i got an old working photon q that i was keeping myself for spares in case...
if you want a part then PM me. x
need advise

i'm confused how to release replace my flex cable
Is there a tutorial how to replace the flex cable with front camera as selled by parts4repair? Or is it really foolproof?
It seems to me like I'm facing the same issues as described in the start post, only in an earlier stage of degeneration of the flex cable:
1. Suppose, the Photon Q is turned on and in operation. When sliding out the keyboard only some millimeters, the screen goes black. If I press the power button at this stage (keyboard slid out some millimeters, screen black), the phone seems to crash and reboots.
2. Suppose again, the Photon Q is turned on and in operation. This time I slide out the keyboard all the way (no matter how fast). The screen goes black. Pressing the power button at this stage doesn't show any effect. Only after pressing it a second time, the Photon Q is awake again, showing me the lock screen - apparently no crash and no reboot!
3. Suppose, the Photon Q is turned on and in operation. I turn the screen off by pressing the power button once, then I wait for some seconds and slide out the keyboard all the way. When I turn on the screen this time by pressing the power button, the lock screen appears as expected and everything is working fine.
All these scenarios also work the other way round, i.e. you assume the keyboard is already slid out all the way and you perform the slide-in movement. Also, this is not a software issue as it behaves analogously during reboot or in recovery mode. Furthermore, I opened my phone. The flex cable was connected properly and I couldn't see any damage to the flex cable. So it seems to be an internal loose connection of the flex cable.
Hey guys i hated my tf300 untill i put a custom ROM(hydro) on it.I have loved it ever since...unfortunately i dropped it and now the screen just doesnt respond anymore..screen still looks perfect no crack or scratch..i have tried full reset and everything i can....should i get i new digitizer??
will that fix it please help..

Cracks are not always visible. But if they're not there, I'd suggest you open the back case and try to reseat the ribbon cables at the touchscreen PCB. While at it, check the flat silver cable connecting that board to the mainboard also. Make sure nothing is jarred loose by the drop.

thanx for responding...i did exactly what you said ..i disconnected both cables (silver and brown) and put them back..more than half of the screen started working, the other part was just dead and those parts didnt work even when i tilted the screen.. like 5 minutes later the entire screen is dead again......do you think its the digitizer?

Sorry for the late reply. I've run into this problem before. When you have a digitizer that works for a few minutes then stops as the tab warms up, (1) more likely than not, there's a crack somewhere or a tear on the ribbons, visible or not, or (2) the new screen boycotting the old firmware. No new screen points to faulty hardware. However, it doesn't hurt to eliminate possible software causes.
The best test I can think of at this point would be to first check the physical connections again (check the connectors and ribbon ends under a magnifying glass, make sure they aren't damaged, bent or stripped), then re-flash the firmware following instructions in another thread, then turn on "show touches" in settings. If you still see "ghost touches" after a few minutes, the digitizer is likely ass-kicked by the drop.
I've had a digitizer on a TF act "leisurely" because of a crack across the width of the bordering black strip that couldn't be detected with the naked eye because it severed the circuit on just the underside. The surface was totally smooth. As the crack spread, it became obvious.
If I had access to your glass, I could've tested for you. Too bad.
Hi all
I have had my nexus 5 for a while now and just as i was flying overseas some strange things happened.
First the vibration stopped working which i knew was a loose connection on the back of the phone. Holding that area down would get it working again. Then the touch display stopped working. The LCD worked but could not touch anything to unlock the phone. I disassembled the phone and assembled it again and strangely it worked again although i didnt see anything obvious. Then is happened again...
I disassembled the phone and played around with it for a while and noticed if pressed down on the connection where the flex cable connects to the motherboard it would work again. but when i would release the pressure it would be funny again. I did this a number of times until eventually the whole LCD/blacklight should shut off. Now i can rarely get it to display anything. The phone is working because the LED light would flash and i can hear the messaged coming through. I just cannot see anything.
I replaced the flex cable with a new one and still the same issue. I replaced the LCD + digitizer + frame and still the same issue. I guess its the motherboard. Can i fix this ??
Now for some more issues:
I bought a broken Nexus 5 while overseas and i swapped the motherboard out and everything works! So it as definitely the motherboard. However, the second motherboard is having issued the the battery. I have every indication the battery is charging. However the battery percentages is stuck on 40%. It would flicker around 39% 40% instantly and when looking at the battery graph on the phone it is noisy, it is not a constant line. The percentage is not a true indication of the battery charge. I cannot get the phone to turn on just by the battery itself no matter how long i charge it for. I have swapped batteries out and i still get the same issue. I have swapped flex cables and still the same issue. Could it be that the second motherboard is also damaged??
I used the amphere app for a while while i had some power and it shows 100mA while charging but a voltage of 0V! When I unplug the cable it will shutoff. Sometimes i cannot even boot it up while charging.
Amphere showing 1%
h**ps://drive.google.com/open?id=0B9KF5ld-Rlu_VWY2eHA5VXE4R3M
What is wrong with these two motherboards?! I do not see anything obvious on the board itself.
I now see the new Nexus 5X is out but i am hesitant in buying it...This is the first phone i have had major issues with.
PS, i gave the latest updated
Thanks for your help guys. I will provide whatever information i can.
It sounds like your 1st phone is having the same problem I have with mine, which is described here: http://forum.xda-developers.com/google-nexus-5/help/main-board-socket-flex-cable-super-t3217281
Use a magnifying glass to see if any pins on the socket are broken. I still don't know if it's fixable.

I bought my brother a second-hand M8. It had a cracked screen but it was really cheap. I put the new screen in and a new SIM card reader. Everything worked fine for months and out of the blue the screen stopped responding to touch. Everything else worked fine as far as I could tell. Even in TWRP touch was gone so I figured maybe it was a cheap screen or something like that. I took it apart and the backlight was falling apart. Ordered a new screen that had the frame with it to save time on reassembly and because the old one was a little tweaked. Same problem, ran the RUU from Windows, ran different RUU's from several threads via Fastboot. Ran the latest firmware package on Santods thread and still nothing. It has to be the motherboard at this point right? The display and digitizer cables go right into the motherboard and the only cable that looks replaceable goes up int the daughter board with the cameras and top speaker assembly. Am I missing something or should I just scrap this mess?

When I swapped out the battery in mine the screen was unresponsive and it was becaus a ribbon cable was misaligned in the connector. I cannot rememer Which one it was but I hope this helps.
