I got a realy stupid problem on the lg l9 P760. It's my girlfriends phone and she droped it once and now the lcd screen won't turn on, but the phone itself turns on. Trying to repair it i bought a new screen for 50€ and replaced the old one and it still doesn't work. What coould be the problem? Did i throw 50€ out of the window? I hope you guys can help me out, thx.
Edit: Any way of accessing the phone to delete content? Or is there a way to install a new firmware on it via pc without using the screen on the phone?
Would be nice if anyone had any idea what i should do or try next.

I think you should send it to LG service center. They can check and identify the problem. I think it's hardware problem.

The problem is will they do it? I already opened the phone and replaced the lcd screen wouldn't that void the warranty?

I think so. But hardware problem is hard to solve in this forum and it's good to try LG service center even you already void the warranty. You may have to pay for their service.
Yeah but if they do it they are gonna bill me like 100€ and considering i already paid 50€ for a new screen that's 150€ repair costs for a 250€ phone not counting any shipping costs. I just emailed them and told them what happened.
I sent the 50€ lcd back and got a refund, bought another one from a different seller. This lcd screen doesn't work either. Only the led lights turn on, the lcd stays dark
Everything else works! The phones turns on, vibrates plays the starting sound and reacts to touch input. What the hell could it be? Is it again a bad lcd screen or maybe it's not event the lcds fault?! I am realy out of ideas and need help.
Edit: A repair website in my country that i wrote a email to said there's a chip on the mainboard that is responsible for the backlight on the screen. That chip must be dead or something, because no screen worked.

I'm having problems with my phone. My warranty is already over btw. My phone is having a black screen, but the touchscreen works. The rest of the phone works. Vibration, keypad buttons etc. I disassembled my phone, removing the front screen (I think its the digitizer/touchscreen) with the connection. Without the front screen, the phone display will light up and I'm able to see everything, but I cannot touch or move anything on that display. I presume its the LCD screen. So now, whenever I connect the digitizer to the phone, the screen of the LCD turns black again. Now, if I loosely fit the connecting wire to the phone from the digitizer, both display and touchscreen will work. But if I connect it properly, the screen turns black again. Correct me if I'm wrong in the screen names. I need advice on what I should do. Thanks!
the same problem for what i asked advice before...but i have sent it for repair some 20 days ago and its still under repair...mine is still in warranty...so i didnt fiddle with it.
what charger you use? i think my display went dead bcoz of the samsung charger...now i swear not to buy any sony handset ever...never faced a problem with nokia sets for over 10 years...i think i overdosed my handset with flashing and charging...anyway...thats a hardware problem so you better take assistance from a service centre.

I've sent to the Sony service centre. Luckily they accepted it. Same, I have never faced a problem with Nokia phones before. Still good and running. I'll never buy a Sony product again
Too bad Nokia doesn't build Android devices. If it does, I'll certainly buy one. Despite the software Nokia phones had always been the strongest. But I doubt a charger will cause such problems...
Is there a way similar to the method shown in this link, http://forum.xda-developers.com/showthread.php?t=1916796 to fix a hard bricked sg2?

Hard bricked. The device didn't turn on after restoring ROM/ flashing new ROM from CWM (can't remember because it was a long time ago). The download mode/ recovery mode doesn't work.

So you wiped/restored while on 4.0.4....yeah, you can bring it back by getting a new mobo.

Why get a new motherboard instead of JTAG
Because it's unlikely a JTAG would work. If the NAND is stuffed, it needs to be replaced. Samsung don't sell NAND's separately (or new motherboards without an authorised service centre performing the swap), so you replace the whole board; either a service centre putting a new board in, or you get a 2nd hand board from a broken/donor phone & you swap it yourself.

Can I use a i9100g motherboard instead of i9100?
No. Read up on the differences between the i9100 and i9100G. They have different processors for a start.

Hi guys,
I bought an i9100 with cracked screen, it would turn on and welcome sound could be heard but nothing would be displayed, not the boot logo. I replaced my motherboard with it. But now the problem is, LCD seems to be not working. When I turn on the device, welcome sound can be heard and I can unlock the phone but can't see anything. While the phone is still on and I lock&unlock my phone using power button, the screen kinda flashes white. Do you think the problem is with my LCD or motherboard itself?:crying: Screen was perfectly fine before I hard bricked my phone.
Thanks.
LCD is Damaged!!

Nah!!! :silly: this cant be a motherboard problem as you can hear the lock and unlock sound and the screen is flashing... this means that the motherboard is fine and working but looks like the LCD is not working.
oops!! This means the only solution to the problem is to change the LCD Screen as there is no other way to fix this!!
Sorry!!

Oh, I was thinking that maybe the part of the motherboard where we connect the LCD flex cable was damaged because my screen still kinda lights across the screen when I unlock it and my screen was fine before hardbrick/replacing mobo.
Go Ahead

Yeah I tried to fix this issue and ordered a new LCD but it also does not show anything on the screen so I guess mobo is the problem?
Hey could someone help me diagnose whats going on with my Galaxy Tab 10.1?
I haven't used it in a few days. I knew it was dead. So I went to charge it. It turned on
and the screen is showing crazy ****ed up lines and flickering. I cannot get to recovery or download mode.
My wife says its this "Carbon Rom" that I installed. I say bull****. If it was, I would be able to at least see recovery mode.
To me it seems the video card or screen, whatever produced the picture got screwed up. Please take a look at the pic and let me know what you think. Can this be fixed? Whats the cost? Is this something I can fix or do I need to go to a repair shop?
Is there a warranty on these things? Its a year old. If I send it to Samsung, will they be able to tell a custom rom was flashed which will void the warranty? Im guessing so... Someone please help im sad
The picture is attached.
Thanks for any help. Appreciated

Its been sitting for 5 minutes now and I went to turn on and it shows a White screen now.
This seems like definite damage. The only things I could think it would be is last Saturday I was sitting by the pool reading
and I cover it back up with my flip case, had it sitting on the chair while I was swimming. It was fine after that though.
Last time I used it, it was Tuesday and it was fine. The only other thing is if my daughter got a hold of it... But there's no way to tell
either way if these were the cause. Any thoughts?
I remember someone posting a topic with the same issue like a yezr zgo or so, i can't find this topic anymore, the problem was with the screen or the cable of your screen, i think he had to replace his LCD screen

Seems in my opinion that you have a screen fault. Maybe it was caused by you without your knowledge or it is a manufacturing defect. It us really hard to say but a screen replacement should fix the problem.

Thank you for your reply.
So you think its the screen, same here. But im doing some you tubing and see that the screen is pretty much just a piece of clear cover that
goes over the lcd screen. I will need a new lcd screen, correct? Is it worth taking apart and checking the cables?
Theres no cracks or damage to the physical screen so it has to be internal.
If anyone can find a link, please let me know. Thanks for your help!
What do you think it would cost to fix at a repair shop? and / or samsung vs. joe blows repair shop?

Screen replacement or LCD replacement? The screen has no physical or visible cracks/damage.

Lcd replacement
hello, i broke my screen lately and i replaced it at a lab,after the repair my screen is sometimes flickering.
i think it was flickering from before the repair but after the repair it got worst,i am not sure.(if it was it was only at the top of the screen now..its every where)
does anyone have any ideas about the source of the problem ?
or if anyone know how to solve it even better
thank you for your help...
If still problem exist after screen replacement then I think there is problem in new screen, try again another screen if still it exist then may be there is serious problem with GRAPHIC IC ( I am not sure about this), You may have to change 220 in your Graphic IC which include soldering but seriously this is very(x3) risky, because any wrong thing can put your phone in nothing.
In case If you brought your screen from online site, then contact to seller and ask them for refund or another screen
Best of luck

first of all thank you for your reply,
as i said i replaced my screen at a cellphone lab so you think i should go there again and ask them to replace the screen?
as i also said its not happening all the time... it can be flickering for 15 min and then nothing for another hour ( on & off)
no way its just a loose cable/connector some where?

Stock ROM or custom one? Cause my screen flickers sometimes too, but I'm fairly sure it's due to adaptive backlight feature in most of the AOSP roms around

Hi Nidhal
I have replaced whole screen with frame, but it seems to be used one (ordered from Aliexpress). It might be the case, I have two complete screens with same issue on my desk, but I dont know how to test them

you have to test each of them separately
take out the mainboard from the old chasis (frame) to test on the new lcd you bought (carefully unplug all the connectors)
then, connect the lcd and digitizer connectors to the mainboard, connect the battery too, and of course the power flex cable should be connected.. power on the phone, and see if the display lit up, then if the touchscreen works... and do the same with the second one you have and i hope you will have a working one al least
watch this video tutorial to avoid any damage
https://www.youtube.com/watch?v=hrOQoOSbldU&t=1s
and BTW, never buy these type of parts from aliexpress! would've been better from ebay or amazon because you'll be covered with warranty in case the part you buy is defected, and for that, you'll get a full refund or ebay will refund you if the seller won't
good luck
