black screen issue - LeEco Le Max 2 Questions & Answers

i spiled water on this phone and now i have black screen all other works and its vibrate when i touch the screen its just stay black
i did replace the lcd but no help can i fix this any how or just trow it and get new?

Has the device been completely flooded with water through the Usb charging port and the speakers?
And did you replaced hole lcd Unit with a complete new one (heating up the screen to melt the glue and so)?
Need a little more information...
Sometimes people are lucky and don't face problems in the future with the phones. But that depends mostly on the fact how much fluid was inside the device.
Normally when the phone was completely wet inside it's just a matter of time till you see issues starts. Because of the corrosion inside phones modules and boards.

[Hardware] Galaxy S3 display no power

Hi there,
my girlfriend smashed her Galaxy S3 sometimes. Now it's done, the glass is broken in the upper left corner. The screen worked fine. A few days later she dropped it and dropped it again... i think she needs some wooden sticks to make a bushfire to call her friends. After some drops the screen stopped working fine. The screen turns black and if i push the upper left side a bit, the screen apears... very purple. I watched some tutorials about replacing the glass'. So i opend the galaxy s3 checked the ribboncables and after reasembling the screen won't start anymore. The softkeys doesn't apears. The phone is booting and make sounds. That means, power is there but no power for the display. I only want to now if the display is okay or not, to buy a new glass. But now i have these power problem. Somebody know how i can fix it? Or do i need a new display with digitizer? It's not cheap... a glass is much ceaper .

Not sure how that happened...
Thanks in advance for looking.
Ordered a screen replacement for my wife's busted S3 screen. Got it, followed directions....got the area around the headphone jack a little too warm, but continued and finished removing the screen. Once I had the screen off, I thought it would be a good idea to power it up to make sure everything was working, especially the top left corner of the screen that was closest to the over heated spot.
To my skeptical surprise everything was cool. Took a picture, looked at some higher res pictures....just to make sure everything seemed normal, to which it did. Powered down, removed the battery and the SIM card and continued on.
I cleaned the screen with alcohol as the directions stated, put everything back together..and NOTHING. The thing is bricked. Any ideas how? I wasn't doing anything remotely related/close to the ROM. The only difficulty I had with any part of this (aside from the aforementioned over heating) was with the two ribbon buttons at the bottom, which got slightly tangled in the tape.
Before I attempt to 'unbrick' this does anyone have any other ideas? Battery is good, phone has been plugged/unplugged while attempting to power up....I didn't take anything else apart so I can't think of anything else that would have goofed up this phone.
If your LCD was broken a new bit of glass wouldn't fix it. It's almost impossible to change just the glass without damaging the digitizer. Most alcohol will destroy an LCD so cleaning it with that is a terrible idea. If you plug your phone into a computer see if it connects, that will at least tell you that the phone is still working, just broken display.

Awesome. Per the instructions: "clean screen with Isopropyl alcohol to remove any excess glue"
Plugged in or otherwise, I get no LEDs, vibrations....nothing. Wondering if a jtag would even be worth it?

[Q] screen problem...but which part needs replacing?

I have a screen problem, and because of the cost would prefer to perform the repair myself. (I've repaired a number of laptops and smartphones in the past.) My problem is that I don't know which part failed.
The accident: I dropped my Galaxy S3 from a height of about 3 feet onto concrete. For reasons too embarrassing to detail, I didn't have the protective case on the phone.
The result: The front bezel around the screen has a 5mm abrasion scratch in it, but the screen itself shows no sign of damage at all. When I put the battery back in, and powered up the phone, the screen did not come on. I see a faint line of green pixels about 3cm long on one spot on the screen. There is nothing else on the display. The phone seems to be powering up and down (not entirely certain because I had the phone on silent mode before I dropped it).
I'm hoping that one of you with more experience might have an opinion on any fixes I might attempt, or tests I might run to determine what needs to be replaced.
Thank you very much for your suggestions!

[Q] Issues after replacing glass: Black out and self typing during calls

Hello all, and XDA developers,
I'm a short time lurker, and flasher, but that's besides the point. I've started my own business repairing phones and I've gotten very good at it, I have extremely fair prices, and this is putting me through college.
I've ran into an issue and I can't figure it out. I try to stay up to date on phones since my job requires that I work on phones, and although I couldn't find all the information about the hardware under the screen of the SGS4 i decided to replace a broken glass screen any way..... well now I have a dissatisfied customer on my hands and i'm doing everything in my power to rectify the situation.
What I did:
I used a heat gun to lightly heat the screen of my customers broken phone, like I have done many times before with other models of phones. I scraped off the old glass, cleaned the glue out thoroughly with alcohol and a small piece of microfiber (like for cleaning screens and glasses). I laid down 3m tape (possibly in the wrong place). Put the new glass on, and PRESTO done.......
The result:
A beautiful new screen, but the wake up motion doesn't work any more (where you swipe your hand across the screen w/o actually touching it), and the screen automatically blacks out once a call is placed. This may be because of where i placed the tape, but a new issue has reared it's ugly head...... It's typing now... by itself.... during calls and at other times. She wanted a different color for the screen and i told her that I will replace the screen and fix the issues all in one motion, but I'm not sure what is making it type on its own. Does anyone have any clue as to what could be causing this issue? I have until the afternoon of 9/25 Central time (UTC-06:00)
Thank you to everyone for existing, this forum, even if it doesn't resolve this issue, is simply a work of art by mad geniuses from all over the planet. I love everyone of you.

Screen

So my girlfriend dropped her s3 the other night , the screen stays off ( does not light up ) but the touch sensors still work, we can answer calls on it by knowing the approximate location of the answer button, any thoughts on what the issue is ? I would prefer to repair this at home rather than make her pay money through a shop, thanks in advance

It is easy to replace broken GLASS.
but i think you will need to replace screen.
If you purchase assembly of glass, digitizer and screen it will be very easy to replace by yourself.

The glass isnt broken, perfectly clean with no scratches cracks or nicks , it just wont light up;
i had the same problem once, had to be sent to samsung (or wherever) by the shop where i bought it
buying a display and metal frame (obviously you can't buy them seperatly) plus glass would have cost almost the same
i wanted to find out whether the screen still works and it's a problem with my motherboard or vice versa so i unscrewed all bolts to access where the screen is plugged in on the motherboard but i didn't have another s3 to do the same and check it :silly:
still don't know how amoled displays work so it might be possible that whatever's responsible for backlighting the display broke

My thought was that the backlight broke or maybe the entire display system is disconnected , I might just have to take it apart for an exploratory operation,
before it went completely black there was a purple stain which grew until two thirds of my display were purple, the lower part where it started was black.
then i managed to open this samsung hardware debugging menu where you can check for dead pixels by letting your display light up in red, green and blue. there i found out that only blue and green pixels very working correctly in the upper third. the next day every purple pixel was dead.
so 2 months after this little stain appeared my whole display was in the same state as your girlfriend's seem to be now.
so i don't think this plug (it sits in place pretty tight) got loose and that's why it doesn't work anymore.
and my sister had exactly your problem. she dropped her s2 and it immediately went black
she hat to sent it in as well ...
good luck
if you find out what's the problem and want to share it, i am curious about it as well
If possible, check for loose connectors first.
I don't know about replacing the screen. The sheer amount of LOCA makes it a messy job.
Probably the display is dead. You'd need to replace the screen+glass.
There is no back light on an oled screen.

is it possible to reattach glass screen coming loose?

So the other day when I attempted to fix my G5 (a double failure as replacing the powerbutton didn't fix the fingerprint issue and the GPS hack didn't work either) I ****ed up in the part where when you are opening it up and you are using picks to separate the back from the front and on the lower left I managed to partially separate the glass from the screen a little. The screen itself is still working fine but in the dark you can see light bleeding from the edge where it got separated and upon closer inspection you can tell its sticking up a little. I was going to give the phone to my kid, but since I'm sure even a little drop of rain on the phone will now ruin it, I'm wondering if there's a way to restick the screen without replacing the whole screen/digitizer assembly.
Sure buds my brother is having the same issue. Watch this video (https://www.youtube.com/watch?v=xi3YD9SN4aM) and it should give you an idea of how to fix it. I'd personally pull it up a little and dab a tiny amount of glue around the edge of the lose area.
