Have you looked at this digitizer and screen replacement video?

p769 is not the same. p760 -765 -768 are the same.

Yes I know that the P760/P765/P768 are basically the same and the P769 and MS769 variant are slightly different... But that video should give you a very good idea and should be almost the exact same process in replacing the digitizer and screen.

Repaired
Just repaired it.
13euro lol
But thr touchscreen is already broking. LoL its really a fragile phonr but i sold it to my friend for 15euro and yeah for 15euro you won't get a working phone lol so hr js happy even if the screen is already broken. It works okay the phone.

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?

L9 P760 LCD screen not turning on

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.

[Q] Need Help with screen

So it looks like a small part of the top of my screen is dead, already tried everything and no luck, The draw line test shows about a 10% of the screen not working. I think this might be a hardware problem, but not sure.
If its the hardware, is it possible to only replace the Digitizer glass, without replacing the LCD screen?
Where can I buy the part (hopefully Original, I read that third party replacements are usually disappointing, because of quality.)? I tried searching in ebay and amazon and was only able to find for the HTC one X not the plus version.
Is it too hard to replace or i'm better saving for a new phone?
Do you mean the area where the status bar is? My HOX+ also doesn't recognize touches there. It happened suddenly 5 months ago when I was playing games . However, I used to it and it is not a big problem, I will give it to repair when I get on vacation .
I already made some researches on the internet and it is not an uncommon problem for touch screens. Yes, it is the digitizer's fault.

Exactly the same problem, upper part of the screen (all notification bar). I have an OCD and this tiny things bug me a lot. I guess now I need to find a digitizer to replace it, the problem is that on ebay and other sites there are not HOX+ available, all are for the HOX.
Is there any difference between HOX and HOX+ digitizers? I thought both got the same screen.
I'm not an expert so I won't fix it on my own, better send it back to service .
Btw. I've read one time that you can put a piece of paper between the bezel and grill to clean some mess up which could get inside the phone. I was wondered that I was able to slip the paper there, but it didn't work .

yes it will work, but you can't only change the digitizer, it's too hard glued together. I broke my LCD connector while replacing the screen although
I was really careful, so it's not as easy as everyone says.
Thx, i will keep that in mind.

Can you send us some pictures?
At this phone you can change only the digitizer or digitizer with lcd i reccomend this one. The digitizer for this phone is glued on lcd.
At my wife phone appeared some shadows on screen when she droped the device on watter.
I opened the phone(bye bye warranty, chinese waranty) and dried the phone. Shadows are gone now.

i think they must be video(not picture) because the lcd is fine. flawless. the problem is about the touches. i dont touch it but it act like i touched it. do you understand the situation? i didnt do anything but it( the lcd) act like i touched it. i dropped the phone few times but nothing happen. until one day, the phantom touch suddenly occur. the touchscreen is quite ok for now. it acts normally since last night. before that i let the battery drained out and recharge until half of the capacity. so what do you think?

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
