Fade Out; WSOD; White screen coloured lines

I know there are others dying to fix this problem. Apparently there is a back "connector" that gets loose. If someone has fixed this please show me which one it is and how you fixed it.

It is the connecter between your mobo and the screen itself. Its come partially lose on one side. You need to dis-assemble your device, then remove and re-insert the little flex cable back into the slot, and all should be well!

hey thanx heaps man. i have it apart and didnt want to put it back together til i knew what the cause was.Wicked!

also the flex/ribbon cable is very sensitive. i will dremel the part of the case that touches the side of the ribbon cable. i am also thinking about coating it with something to make it last longer. replacements cost 40 euros

All good ideas! tell me what u decide to coat it with. i put it back together and made sure that connection was in right but it didnt work, (WSOD 5mins after assembly), going to try putting something underneath to keep it tight when its all fixed together. thanks again for your help guys.

I have the same issue, but also my touchscreen is affected to, touchscreen wont work when you slide keyboard open, sometimes i have to open very slightly for touchscreen to work.
The ribbon cables are very delicate, and it is known that slide open phones are bad for these ribbon cables, if cleaning and securely connecting them and the problem persists, its probably a damaged ribbon cable.
My phone does the same screen problem, where it sometimes gets lines down one side of the screen and gradually fades out, putting the phone into standby and back on brings the screen back to normal but it sometimes repeats several times.
I have noticed that it very rarely does it when the keyboard is exposed, it does it most frequently with the phone closed. And its more likely to do it when there is alot of white background, like in certain option screens, for example when in camera options does it alot.
In my case i suspect that the screen itself is faulty (hardware) and the touch screen cable has been damaged, since sliding out the keypad affects on weather it works, doesnt work, or works as if not calibrated.
emjay87, sorry to say it but i suspect your display is faulty or the ribbon is damaged. Replacement is easy to fix, but make sure you get the right screen, as far as i remember there are 2 different screens for this phone. They have different ribbion cable connections. One gold and ones white i think.

OMG White Screen!

Ok I need help from the gods of xda
I dropped my tilt the other day. When I picked it up everything seemed fine, yet the screen was completely white. No signs of cracks or a broken lcd. So I've tried the following: Soft reset, Hard reset, took out the battery, took apart the phone and disconnected the lcd and then re connected it. Still the same problem. WHITE SCREEN!
I can still receive/make calls, when i touch the screen in places where i remember the menus to be it still responds due to the noise, also the open and close noise still sounds.
The phone was bought new on Ebay, so i don't have a warranty through them or AT&T. After much research I hear people saying the same has happened to their phones as well and that there is a ribbon or flex cable problem. Something about still giving power to the LCD but not data, thus the white screen.
Now what I dont understand is do I need a new LCD because it has that ribbon/flex cable on it???? (link)
or
Do I need this product?(link)
Both contain a "flex cable" so im confused and frustrated, someone please help! any ideas would help

hi there, would it be possible to post the link to ebay item? i also need a new touch-screen.tnanks

I am curious about this as well. I have a friend who has a hermes and he mentioned to me that that his screen was starting to go white like explained here. I look at his phone and I also noticed that the bottom hardware keys were not working at all.
I am wondering if this same ribbon cable for the LCD would also be the same one for the bottom keypad and if I fix the screen the keys will become active again.
Anyone have any experience with this?
Thanks,

Tuck in for a long read and perhaps no single answer for all cases:

In short, yes the d/pad cable and LCD screen connections are linked which is why it is not uncommon for the white screen to show up when the d/pad is not working.
To the OP - I would just point out that if you get the white screen after a fall it may just be a loose connection at the d/pad and no need for new parts.

But let's not start discussing the white screen here, please use the first link I gave above if you need to post.

a user i dont recall now his name,fixed is whitescreen by replacing the camera,open the device and remove the camera module, reassemble to test.

What else can I replace? (Screen issue)

My screen started turning white awhile back. I now have a screen and a ribbon cable.
I replaced the screen first, and the new screen shows only white. Probably the cable, right?
Then I replaced the ribbon (keeping the new screen in) and still got only white.
Hooked the old screen back up with the new ribbon cable, and now I have a working screen, but the colors are horribly washed out and it looks like it has lines of white every other line or so.
Is there anything else I can do? Should I give up? Suggestions?
Thanks guys, I don't know if I've ever posted here, but you've been a great help for many years!

Assuming the cable connectors are good and clean, it is now generally accepted that white screen issues are caused by faulty chip connections on the d-pad daughter board. If you can replace that at a reasonable cost, it might be worth it.
Your new screen may have been white because either:
1
The d-pad board is indeed faulty
OR 2
The new screen although made for the Hermes is not an exact match. You MUST replace like with like. There were at least 3 different and NON-compatible screens made for the Hermes (by different manufacturers - Toppoly, Samsung etc). The only easy way to know if the new screen is the correct one is to compare the code numbers printed on the rear of the screens.

I'll have to keep a eye on eBay for a d-pad... There are a few parts phones out there now, but I can't tell if they have the right parts inside or not,
Does the serial number tell me what screen components it uses (IE Serial number XXXX+ came with the black flex, XXXX and below came with the white flex, etc?)

It may be that you can match screen to seriel number, but so far as I know, nobody has done that detailed matchiing task. So unfortunately at the moment, the only way to tell is to dismantle and see the number.
A thought crossed my mind about the d-pad board. Have you read the long thread about fixing the whitescreen problem. One reasonably successful solution is to place a little padding on a d-pad chip to press it against it's board. (simply put the issue arises from fractured chip solder joints - caused by finger presses on the d-pad). I don't suggest this as a permanent fix, but if such padding caused the whitescreen to disappear, then at least you could be sure it is a d-pad problem.

My boss is a parnter in a Electric car conversion company, and they build all sorts of small circuitry (including surface mount stuff) so I'll take the board into one of them and ask if they'll re-do the solder joints for me, thanks.
I never posted here, but I got all the information I used to try and fix it here, but in all my searches, I don't think I ever read anything about the Dpad untill the past few days... So thanks alot for that...

One thing if you have the solder reflowed (obvious to some but not all!!) remember to peel off the sticky plastic layer on the opposite side or you'll end up with a sticky mess

[Q] Screen flickering, what should I change? Screen or Motherboard?

Hi guys, if someone here suffered from this kind of flickering >>VIDEO LINK.
How do you managed to fix it? What part did you change, the screen or the motherboard? Thanks. Really need some help. My phone now is unusable.
]]]]]] UPDATE 1[[[[[[[
Hi guys, just got my G2 back from the dead.
I send my G2 to a phone care in the city and they said my lcd is the problem, they changed the lcd+digitizer (the whole half of my G2 )and now the problem is gone. But When I got home I noticed vertical lines on my G2 when it is turned off, not really noticeable but if you look closely you can see the vertical lines and thinking that they change it with a low quality LCD. Even in white backgrounds you can see the lines but only if you have a clear eyes . I compared it to the original LCD and I don't see any vertical lines at all, it's all black. But the frame of the new lcd is solid like the original. So, in the future, will this new LCD survive or should I go the phone care again? Thanks!
***********UPDATE 2************
[UPDATE]
I think my G2 is working now after playing games for hours in 5 days, no flickering/stuttering/jittering noticed.
But, my IMEI was change and it was rooted jellybean when they give it to me. I don't know if they change the motherboard or the whole phone except for the body case and the new screen i purchased. I asked them about the changes of the phone because it's my second time returning the phone and the women on the counter said their tech just adjust something. I don't believe that, and then I saw the IMEI changed. I didn't ask why my IMEI was change, i'll wait til something goes wrong on my G2 and sue them. LOL.
I have some questions regarding this.
1) I'm not really sure if how an IMEI was change, is it for changing the motherboard?
2) Is it legal that they don't tell me what they change on my phone?
For now my G2 is still alive and no problem after upgrading to lollipop + root + twrp. Hope it goes all well now.

i went to lg service and they changed some filters on motherboard in 2 hours filter,EMI/Power 2 quantity i read on the paper. i was on warranty..

That looks crazy, it definitely would be a motherboard issue, or, I had a simliar issue while repairing them (I've re-sold about 20 of them) the flex ribbon sometimes gets dirty, or out of place(the one on the bottom under the speaker). You have to remove the back, then remove the speaker(6 screws I believe on the bottom, it;s an L shape). Once you do that, make sure the square flex cable is connected well, and there is nothing touching the circuit right under it(It has a plastic tape to keep it from touching).
The connector I'm referring to is right next to the USB one on the flex. For obvious reasons I got the image from ETrade supply. You can clean the connectors with 91% or higher alcohol, DO NOT use anything less.

I think i'm out of warranty because i bought it when it was newly released. Do you think lg sc will fix it by paying them cash?

When you replace your lcd they always tell you to make sure you have both connectors securely in place above the usb connector. One of them is the ground connection to your LCD!
Make sure both are fastened correctly and test before you seal your phone back together.
Keep us posted

After few days of youtube and playing games, my phone started stuttering/flickering again like on my first post -_-
I paid for the new LCD that they change, should I pay another bucks for the motherboard problem? or they'll give me a refund for the new LCD I bought that didn't fix my problem? Please someone reply me asap. Thanks

This error is on mainboard. Fix it is very simple. I has lot about 10$ for this solution.sorry bbecause my english's bad.

Hi guys, i have a similar problem. I bought a new lcd on aliexpress.....that is the video of the problem....
http://www.mediafire.com/watch/glzqihgdzz12jsj/Lgg2_lcd.mp4
The strange thing is , not in every operation make the same problem. after days i see that problem usually on facebook and a lot on clash of clans .
I make also a screenshot on the clash of clans and when i open the picture the screen flickering .....
its like when the phone show some combination of color make this problem

My Lg PRO 2 Phablet did the same from first turn on, flickering on and off, very dissapointed as i had mine direct from Hong Kong and couldnt send it back. What i did was to tak all of the screws out and take the plastic back off, then re fitted the back only, no screws and turned on, no more flickering. Then i put a couple of screws in and tried again, still no flicker, then after a couple of more screws by the sim socket it started to flicker again! Now i just run the phone minus a few screws, it must be a pressure thing!

Hi, i have exactly the same problem, specially in combination of colors (green red and blue most of the time). how did you manage to fix your phone ? did you change the mainboard ? thanks for your help.

Strange black screen issue with fully working screen (electrical, not physical).

Hi,
i bought a factory refurbished I9600F from aliexpress. It worked great for 3 days, then the phone became slow to respond, the screen was flickering in yellow-green tones, and then wouldn't come back on but stay black. (but I would still get notification sounds for incoming messages, the notification LED was still working, and the menu keys also light up when I press home/power).
Pulling the battery fixed the issue once, but the problem came back after 1 hour.
I managed to revive the phone once more by pulling the battery and holding the power button to drain all remaining power in the device. The phone was working again for a few hours, but now it's back to having a black screen and even the power drain method doesn't work anymore...
So i'm guessing that replacing the screen won't fix the issue, since the screen is working just fine for a a while (both image and touch are perfect) - but then somehow there must be some electrical issue that causes the graphics unit to malfunction.
I checked the easily accessible connector to the left side of the battery, but it seems that the screen is mainly connected via flex cables that cannot be accessed unless you heat up your device and pry out the screen.
I have found some information on the internet that pressing hard on the spot where the flex cable connector is might fix the problem, but this didn't work for me.
FYI, I'm running the default Samsung firmware the device shipped with and used Kies + OTA update to get the latest official FW. No rooting or any other mods. Just some regular apps installed.
Any recommendation what I could try to fix this problem? Thank you all!!!

BTW, I have found similar reports on the internet here:
http://forums.androidcentral.com/samsung-galaxy-s5/405238-galaxy-s5-static-screen-won-t-turn.html
But the linked how-to-fix guide states that heating up the display assembly is only recommended on devices with a broken screen... So now I don't want to risk breaking my working screen.

So mainly my options are
a) open the device to check the flex cable connection
b) buy a new battery to see if that solves if (some people have reported success with a different battery)
c) buy a new screen assembly on aliexpress for around €135 and hope that a new screen will fix it...
Thoughts?

I'm going find out the cause for this issue. I've disassembled one device that only lights up when it is warm. If I put it in the cooler it refuses to light up for some time after that. I tried placing only the screen in the cooler, also only the phone body in the cooler, but couldn't find any difference doing this as it refuses to light up both times for a couple of minutes then it works great again.
I've ordered another device that had its screen shattered so I will try my current screen on that device.
It could be some internal hardware fault in the mobo, it could be the LCD connector having a bad connection somehow, it could be the screen assembly itself, but I will find out eventually.
I've seen many places on the internet where people say this is a software issue. There is a very simple answer to that question. How could it be a software issue if not even the boot logo shows up when you start the phone?
I will keep this thread updated.

Verified that this is a problem with the motherboard. What circuit on the motherboard could have problems with cold temperatures? The main power one? If so, I will try replacing it with a different one.

Update: Was not able to fix it. Motherboard is now scrap.
