After replacing lg v10 screen, i tested the device thoroughly.
Device works fine with a new LCD screen as long as not all components are connected (e.g. front camera en 3.5 mm jack)
The problem i keep getting with the LCD is:
1. Connect 3.5 mm jack and LCD screen blacks out.
2. Screw on back panel and LCD screen blacks out.
3. When charger is connected LCD screen blacks out immediatly.
In all three situations the LCD black outs and if it turns on you see white lines on the right side of the screen.
If you thighten the screws too hard the LCD screen also in black out.
If you plug in the charger the lcd immediatly goes black.
Now I wonder where the problem lies. Is it the LCD screen or motherboard.
PS: this was a water damaged phone which was repaired by a store with industrial equipment.

Cliffs Notes version:
Broke the glass on my Rezound but the digitizer and LCD were working fine. While replacing the glass I broke the LCD, so I bought a replacement from ebay.
Now the new LCD will turn on to show the initial HTC screen and then it goes blank...no backlight or anything else on display. I can boot into hboot and fastboot. When I try to boot into recovery I get the blank screen. Did I get a bad LCD, or is there more to it than that? I managed to find the broken LCD and it has similar behavior, so I'm worried I may have broken something else on the board while replacing components

make sure the rainbow cable isnt pinched anywhere and that it's plugged in 100 completely, ive had this happen to me when i first started to take apart phones with the Inc. even if it's a slight angle it will not make a good enough contact.
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 .

Multiple posts on the subject including a you tube video on replacing .You need to search them and decide .
Accessories may have more information .

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?
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.

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.
Hey guys, recently my moto z had its battery replaced but when I got home I noticed that the top left of the screen had this white splotch that looks like sunshine shining thru. The screen and touch in that area work fine there's just this "aura" or "glow" I'm attaching a picture to help.
Could be a pressure mark or affects from heat pack to melt glue to get rear case off.
Either way you're not gonna calibrate it out ??
It's surely a burn mark caused by excessive heat from the screen removal process. Unlike lcd screens which turn off pixels and return to normal function when cooled off, oled display pixels just die... Some phones get those kind of marks from the cpu overheating the display from under it.
