    Hello I think the ribbon which I think is the little small part has a small rip on it can this be fixed with tape or any of their way?

    So, based on step 10, where it says you can stop here if you have a pre-assembled frame, I bought this http://www.amazon.com/gp/product/B00T733... LCD/screen/frame. But it turns out that like all LCD/Glass/Frames it doesn't include the rear facing camera, earpiece speaker or vibrator unit. So if you buy one of those online and stop at step 10, you will not have a rear facing camera, earpiece speaker or vibrator in your "fixed" phone, those are all attached to your old frame. Now I'm going to have to separate 2 LCD/screen from 2 frames and start from the beginning, hoping I didn't damage the speaker as I tried to remove it.

    If anyone has experience with this and I'm wrong please let me know.

    There is no need to remove the shorter screw, it does not go through the mother board

Josiah Leas -

Did you get it working i have the same issue? the picture displays with the original screen but not with the new one. i have tried 3 different screens and get the same on all of them. i even tried updating to the latest software but only get a black screen, no picture.

When i have had this on iphones i just so a reset by holding down the buttons and the screen starts to work.

Please someone help

Same here! I also findout that lcd still works, if you get some flashlight on screen in a dark room, you will see that only backlight not working when battery plugged. I tried to baking it but it still didn't worked. It's obvious that backlight could properly operate as it works when you take off the battery. I'm looking for solutions, if I find any, will wrote it here.

Did someone find a solution to this? I also replaced my screen and it keeps black solid when I turn it on, even with the touch working properly.

Hello. I was just wondering if there is any advice on where to buy a good replacement screen. I was going to buy one on Amazon, but the reviews were spotty. Are there a bunch of chinese knock offs for screens? What is a reputable source?

You can look on eBay for a used screen so you know it will work. Feel free to email me if you have any questions- josiahleas@gmail.com

so I succesfully replaced my shattered screen,but now the loudspeaker on the back of the phone no longer works. I've tried re building the phone again, and it still doesnt work. Any suggestions?

I cracked my screen and can't unlock my phone because parts of my PIN don't register - if I replace my screen on my own, will all of the data on the phone be deleted? I checked with LG customer service and they said sending it in for official repairs deletes all the data.

aac - Reply

If you send it to them they will probably wipe all the data like they claimed but doing it yourself should have zero effect on your data.

Jerry Noftz -

They are more than likely sending you a refurbished phone back to you. That is why they claim your data will be wiped.

I have replaced the screen on an LG G3, the first one had a dead spot in the digitizing, it was replaced by the supplier without a problem and a new one was tested and working at teh store. Once installed in the frame, the only thing working is the backlight. Any input on the cause and a possible solution would be helpful

Hi, I actually have a question, My LCD is replaced but there seemed to be an issue, my screen is blurry. Same as when the phone was broken, only difference is that the screen isnt broken anymore. Is it possible that IO caused this by having used metal on the ribbons? Is there a way of fixing it?

Thanks in advanced.

This is my first time I attempt to repair a screen. I'm scared of buying a screen that might exclude the LG logo at the bottom or that the screen ends up being a cheap knockoff. Most vendors (including the one featured in the "relevant parts" list) have the image of the screen part with the logo photoshopped out. I cannot figure out if it's to avoid legal issues with LG or if their screens actually don't have the logo on it.

Am I being too paranoid or should I be searching differently?

Abraham Carrasco - Reply

I have Installed the screen but since then my battery life is decreased drastic, and i know that it's the screen because the display now takes 55% from the buttery, and before it was around 30%!

Additionally, the touch does not work good when i put a glass screen protector on it. it's a something that have never experienced before. what can we do about it? Thanks a lot...

the cost of buying parts for this LG3 is so high that l would opt to buy a new phone.

I just replaced mine yesterday and when I powered it on, nothing happened. But after 10 minutes, it turned on and you can see the lock screen but you cant do anything there because the touchscreen does not work.

I've just cracked my screen a little but need it replaced and I was quoted £85 to replace my screen! I thought it was a bit expensive and I explained to the guy the LCD seems to be working fine but he told me it needs to be replaced as well as you can't replace the screen without replacing the LCD. Is this true?

@Lee Schlosser did you find reason for loud speaker not working? I am facing similar problem after replacing the screen the loud speaker is making wierd noise

Saif Idrees - Reply

Sometimes the backlight problem (backlight remains on) is related to other issues, like unconnected or mal-functioning proximity sensor.

Thats another story in its entirety. Let me get straight to the point now. Would any kind giving soul feel it upon their hearts be able to donate a screen repair kit and screen? Blessed we will all be if ypu are able to do so.

Got my g3 a while back second hand. I think it's got the motherboard replaced .(different imei in rom and oj the phone back) Also, the gray isolating tape is missing, instead there's a piece of transparent plastic there. My question is: could the lack of proper tape caude distortions in the headphone jack? (Some interference maybe?)

Bagoly Bence - Reply

There are some details of the "screen replacement with frame" missing. In addition to transferring the haptic buzzer, front and rear cameras, earpiece speaker, headphone jack, bottom board and metal shielding tape there are some small additional parts.

There are three small rubber insert parts; two on the top and one on the bottom. The last part to transfer is the ir blaster lens which is quite difficult without damaging the lens. I know since after transferring it with some difficulty I now have a severely hampered ir blaster now. Knowing this I would now opt to replace the screen only and take the time to heat the adhesive and remove replace the screen. Really the frames should be sold with the it lens installed already since it is near impossible to transfer this tiny part.

my screen is getting blue

how i can fix it

1: Its important when repairing any device that you buy quality parts from a reputable source. Hopefully most of you know now that saving $10-15 on a inferior part does not really save you money. It in fact, takes you longer to do and more frustration. BUY GOOD PARTS, PAY EXTRA FOR GOOD PARTS. THIS WILL SOLVE MOST PEOPLE'S PROBLEM. PERIOD.

2: When replacing the screen on LG G3 it's very important that the metal mesh, On the flex cable at the bottom of the screen... is placed EXACTLY as it was placed originally in the phone before the screen repair. VERY IMPORTANT(REFER TO STEP 10). If not the screen will go in and out. If you continue to have issues with the screen afterwards.. Try putting some CapTon Tape over it. That should resolve your issues.

PS: If that does not fix it.. its the screen or the device itself. I would suggest looking for any signs of water damage or small black marks on the Mainboard (implying a short) and take pictures to show your customer so they believe you.

Better idea about the screws: DON’T REMOVE THE SCREW CIRCLED IN RED. It holds the camera lens cover and volume/power buttons on to the plastic frame. Just take off the frame with that part still attached.

I know this is from a long time ago but my lcd panel died after a software update. I was 28 months in and my geeksquad warranty had expired. I had visions of trying to get another year or so of use on it. I'm tired of spending 1k$ every other year. Have you guys had any success in the screen repairs?
