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?

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.

Just wondering if anyone here could shed some light on this matter. My daughters shift LCD appeared to stop working. So I replaced it to no avail. Still not working.

Did you do it the replacement yourself ? Or did you have it done ? The reason I'm asking is because if you replaced it yourself, did you happen to check the Flex Cable ? That is usually the cause of the Screen acting weird, or not responding. If the Flex Cable is cracked, or Split it does not work correctly.

Yeah I did it, I've had plenty of experience changing lcds and digitizers so no issue there. Guess ill have to open it back up and check the other cables.

Check out THIS thread. The Cable you want to really take a look at is partially shown in Figures One / Two where it connects. It is the Flex Cable that connects to the Keyboard. They are know to wear / crack over time form the KB being slid in, and out.
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!

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.
Forgive if this has been mentioned, it is difficult to sift old threads from my phone.
Mine has had the issue of front 5 buttons not working. The strange issue is that they do work when I reboot, until the phone sleeps. Then they do nothing. it makes me wonder how it can be hardware related. Tried restoring to stock and it comes back
The symptom seems software but my inner helpdesk says a full restore points to hardware. Thoughts? Replacing that flex cable would be a pain (I did open her up to check for loose cables)
any thoughts at all?
This has now turned into when i slide the screen open, the screen shuts off. Please any help?

That sounds like a failing slide flex cable. They typically run under $20 on eBay. If you decide to do the work yourself, just be careful and take it slow when separating the housing from the LCD. HTC used a ton of double sided tape to attach the LCD. I'd recommend reviewing the ifixsmartphone repair guide. The have some great shots of the interior of the phone.
Also watch a couple of YouTube videos showing the dis-assembly process. This video from Repairs Universe shows the process pretty well. Note the cables at 6:52 in the video.
On the top, the left cable is a part of the slide flex cable and it contains your front facing camera, light and proximity sensor and speaker.
The center cable is for the digitizer. Twist or flex this too much and you can ruin your digitizer.
The right cable is the LCD cable.
On the bottom you have the other end of your slide flex cable with the front buttons and trackpad.
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

Thanks for the reply, I'll try that, recently the USB data stopped working, PC doesnt recognize the device anymore but I guess it is still charging because it hasnt turned off.
Hi there, i'm French and i bought a motorola photon Q on January 2015. Today, the phone goes into the screen blacklight issue...i ask your help because i don't know what i have to do...a priori it's a well known issue on photon but i didn't success to find a solution...
The phone's screen is black but the phone is in fonction, i can take pictures or receive SMS...just the screen doesn't display anything... i tried to maintain power+vol down buttons but when i reboot i don't have the motorola logo, as instead the screen display a cloud of dots white, black, red during few seconds and turn on black screen again...i can't have the motorola red logo, i don't know what to do...if i have to replace the LCD or not ? re install a ROM by PC or not...the phone is out of order ? that's the flex cable issue ? i don't want to buy a flex cable or a LCD if the problem doesn't come from that...i'm block and i hope you can help me...
Thanks in advance
Did you lose LCD or backlight? I don't know if only backlight could be broken.
If your LCD is completely black and nothing at all, I suspect your flex cable is gone, which is a fairly common problem of this device.
btw, Did you buy a new one? it mostly takes +2 years before you see any problem there, though.
Thanks for the answer,
i lost the LCD, it's completely black...nothing...
i unmounted the phone, check for the plug and i noted that the flex black cable is damaged, the surface becoming bright grey with friction of the keyboard open/close mouvements... Maybe a short-circuit have also damaged the LCD...i'm wondering... i don't know what i have to order... simply the flex cable ? or flex cable + LCD ? i don't want to buy some pieces if they are useless or the phone still goes out of order with...
I used to use all the time, it's my computer, my phone, my organizer... it's maybe the reason that the phone went out of order quickly.
Where can i buy this flex cable for reasonable price in Europe ? with sending and custom fees that cost more than 50€, it's very expensive for an eleven mounths cable lifetime :/
I have to remind you that replacing a flex cable is not easy, unless you are comfortable at these things.
Why don't you get a decent used one from ebay or something? replacing the mainboard will be a lot easier than taking your screen apart.

I think i can, i've already repaired hundred times my old droid 2...
i can't buy an other cause it's too expensive...this one already cost me a kidney with sending and custom fees... furthermore in Europe nobody sell this phone... i must replace the flex cable, it's less expansive :s and even like that i think it's too expensive...50€ for a cable it's a power abuse...
Do you know a website that sell spare pieces in Europe ? maybe it will be less expensive to buy it directly here
thanks a lot
