Newton Rings on LG Optimus Black Touchscreen

Hi,
I notice that when I touch the screen I see strange colors- like rainbow bubbles under the screen.
Is it normal or not? if you touch your screen, do you also see like rainbow distortions on it - like oil spots? (newton rings)
Do you suggest me to ignore it or take it to LG and ask them to replace/fix it?(my phone is 7 months old)

that is a normal thing, but you shouldn't be pressing like that the screen :/
it's Liquid Cristal Display = LCD so it is normal to see those colors when screen is pressed, but stop pushing it XD you can damage the screen

Lol, thanks for the information, I thought this way but wasn't sure.
but what if I also see those strange colors even when I press not very strong on the screen but normal+ ? Should I take my phone to repair? (it's free for me, lol)

I think so, it might be a defective LCD, and if its free you should do it... I mean it's somehow normal [because of the liquid cristal] but if that happens whit normal pressure then is not that normal...

Maybe the gorilla glass (the one you touch, not the LCD) is softer/looser than normal and not rigid enough... I noticed a softer/thinner Gorilla Glass on the Black than other devices.. Quite annoying sometimes, it makes the device feel fragile or cheap XD

Did someone also notice that when applying little pressure to the screen, like an oil spot appears and in some spots the screen feels flexible when touching it a bit stronger?
It looks like this: (It happens only when I touch the screen a bit stronger than normal)

Mm it does happen but not that large and when it happens it gets back to normal quite instantly.. Could be a counterfeit OB lol... I always knew that the Gorilla Glass was not normal on OBs.. you should go to an LG service or somwthing like this to get it checked.. It shouldn't be like that, at least wheb applying a small pressure

Ok, thanks for replying, now I know that my OB is not the only one with this defect.
I already sent my OB to repair when it had other problems in the screen and they didn't replace it with a new OB
now I'm going to send it again to my Cell provider and I'll ask them to replace my defective OB under LG's manufacturer Warranty.
Any ideas how to convince them to replace my defective OB with a new one and not only replace the digitizer or lcd screen?

sorry

Posted by a mistake
sorry

Hi,
I found the specific name of this phenomenon: newton rings
there are many threads in XDA about this phenomenon but no one about OB.
It appears only when I touch the screen, (maybe it's because I always keep my phone in the pocket.)
It looks like that:
Is my LG Optimus Black defective or it's normal?

This is only what I think, but to be honest I feel that's not normal, I mean even if I press really hard my phone's screen it doesn't look like that not even close to that, I think you should send it to techs

HELP! Xperia Z Now has a black screen!

So hello,
I am at vacation, Had my xperia Z, was trying to test the water resistance of the phone, so i decided, ( i never did something with water and my phone before, because i was worried something would happen) to make a video when jumping into the swimming pool,
so i did.
after that, ( about 3 hours later) my screen starts to flicker. after that, the brightness goes down.
still flickering.
I decided to do a CPU stability test, just to check.
CPU came at 50.3 degrees (!!!) ( WTF!), then i turned it off, because i thought this was a little too hot.
After that, i was sleeping, next day it was still the same, still flickering and low brightness, but everything was working. I turned it off again,
Yesterday i turned it on, and saw nothing on-screen anymore, although i do know that the phone still works, because of this:
If i hold volume up + power button for 10 seconds, it still vibrates,
if i hold volume down and power button, it makes a screenshot ( i hear that sound)
and when i press on the screen, i hear that touch sounds.
-----
Can someone help me?
Do i have to repair it in a repair center? How much will it cost me? or is this in warranty ( i think no)
Also additional info:
Phone = Rooted
I had an custom ROM ( Honami )
I had all covers closed
I did NOT go one meter deep, i jumped in the pool and held my arm high, so it was almost not under water
it was NOT for 30 seconds/30minutes, just jump and done
Thanx!

The act of jumping in the water probably caused water to be forced into your phone.
It's highly likely corrosion and/or shorting of components has occurred as you continued to use the phone after water got in.
You can try leaving the device turned off in a bag of rice for a week or so, to see if that removes the moisture.
IMO, though, permanent damage has occurred and you will need to take it for repair.
Your warranty is probably void.

Might be that u did not close the port properly, is the indicator turns colour? If thats not the Case then try reflash stock Rom, and if that does not solve the problem, try checking for possibility of water in ur device.. It might come through the back panel.

What indicator? The LED indicator? That gives several colours, when i turn it on it is pink, and when it is on, it is either green flashing sometimes, or blue flashing sometimes
and how to check for water in my device? ( besides letting it in a sack of rice for a week, because then i already know that wont work)
And if i let it repair, what will it cost? Since everything is working, except the screen
And i dont know how this works, but i saw some news sites that posted 2 days ago that the Xperia Z ultra has exact the same problem as i describe now, could it be thatsome xperia Z models also face the exact same problem?

He means the "water indicator". If you open the headphone or usb port flap, you'll see square white stuff in the corner. That's the indicator. If it is no longer white (it becomes red when water breach occurred), you have to take your phone into repair, and your warranty is already lost so you will be charged for the repair fee.

Have to say, my screen is not completely blank, i could see on the lock screen the time, it was very dark however, but i still see something
also: cannot look now if it is pink, i think its pink, because i already saw that,
and if you mean warranty is already void because of root, i can relock my bootloader and flash to stock fairly easy ( have done it already couple of times, so, can do.)
and still, the big question, what do you expect me to payfor the repair?
and shall i bring it to sony? or to T-Mobile? or to another random third party repair shop in my city? ( last option is most affordable i think, but not the most secure, so what do you guys advise?)

If the indicator is red, your warranty is void.

If the screen is very dark and you still can see whatever it displays, probably the LED IC (IC that controls the LED illumination) is broken, because the LCD is still working, but without any illumination. To bring it to sony is the best I guess.
Well, your warranty is void because the indicator is red (or pink-ish, not white anymore) because of water breach. Not because you unlocked your bootloader.

I could only see the Time in white, very dark, but this way i know it is not completely broken, does this mean the same?

seems like sony does not repair phones with water inside at all..., not even outside the warranty
What a service..

That would be because repairing the average water damaged phone would cost more than replacing it when you factor in that probably every component has suffered damage, labour costs etc.

So instead of helping SOME people, they choose to help no one, because it COULD be that everything is damaged?
Not everyone has Water damage everywhere

Yes, that's correct. Basic common sense would suggest it's cheaper to supply a new unit at cost price than to mess around paying someone to diagnose the fault and replace the whole internals of the phone in most cases of water damage. That's if the phone is even still under warranty, which probably isn't the case in 99% of water damage cases, which are normally caused by user error or negligence.
As for saying that not everyone would need most of the components replacing; you have no idea what is damaged inside your phone. It could be the case that the entire motherboard needs replacing.

Water damage? Send the phone to be repaired.
Sent from my C6603 using Tapatalk

-Dude, you JUMPED into the water. The extra pressure caused by the jump plus the extra depth you dive in (larger than the one of one meter-written in phone's specs) caused extra pressure, therefore water leaked into your phone. Haven't you read the specs? Up to one meter depth, why did you think they informed you with that?
- check under your flaps (headphones, charger, etc), there is a tiny white strap. If that spot is still white, it means the water got into your phone not through the flaps, so you can claim a faulty device by proving that your flaps were closed the time water got in (this also means not to tell them that you actually jumped into the water with your phone). If your stripes are red, it means that water got into.the phone through your.flaps, therefore you can kiss goodbye your warranty. Next time you get a waterpfroof device read carefully its specifications.

Cheapest way to fix phone in that condition is to buy another one. Original front housing for xperia z is too expencive (touchscreen and lcd r glued together), and probably ur motherboard is damaged as well. As a official Sony servicer I recommend u to buy new phone. And main reason why Sony doestn't service phones damaged with liquid is the one that kingvortex said.
And jumping into the water isn't such a good idea at all man. :\

Dim display trying to light up
Hello,
I've got the same problem. I was jumping with my Xperia Z into the pool and doing random idiotic ideas. Now is the phone functioning properly without any problems. But still there is one problem. My display is extremely dark. I can see on it only in the night. But when I'am playing with the phone more than 5 minutes the display is trying to light up. I set the brightness on maximum. Only 2 times it was on maximum for aproximetly 4 seconds but the phone is still trying to light up to the maximum. What can i do now? Thanks

Haven't you read the previous posts? Check if the indicators are red, if they are there's nothing you can do. If they aren't you could give it to sony to repair, but don't tell them what you did....

[Q] Guide: Xperia V disassembly, how to repair broken display?

Hi,
the touch screen of my Xperia V is broken and I'd like to replace it myself. It's not the first time for me that I repair a mobile device myself, but without a disassembly guide, it is difficult for me to identify the parts that are fixed by glue. I don't want to break anything that is still working.
I already found a russian video on YouTube, but it seems to me that the display is not taken apart from the other parts of the device.
Has anyone here done it before?
Thanks in advance!

Hi,
I've managed to remove the display. Mainly because it was really damaged ... heating the display and "bending" with a small tool.
It's really hard as the glue is quite strong. As my replacement screen is "on it's way" I'm not able to finalize the work.
I'm kind of stuck in the part when removing the "middle, plastic" part...

display is connected to body with really strong glue. Remember that it is impossible to remove old display without breaking it. Second thing is that with new display the phone most likely will not be waterproof

Hi! I broke mine last night. How did your repair go when the part arrived? I also could only find the russian video without the screen being removed
How hot did you have to make the screen? I was thinking of using an iron with a cloth around it.

Hi Folks, I'm curious to hear how others are going - I managed to break my screen this last week, Hoping to replace it but so far taking out that glass seems to be a tricky thing - any suggestions? How did the iron and cloth go?

There's no way.... You need to buy a new housing with the LCD and touchscreen built in, and then move all your bits over. That's why the russian video of the guy removing everything doesn't remove the screen.

I just ordered this: http://www.parts4repair.com/complete-screen-assembly-for-sony-xperia-v-lt25i/ I will see how that goes. I got tired of using my old SG1 so it's time to fix the V...

Good luck. Careful with the tiny, white antennae cable running from the main board to the bottom. I twisted mine a little bit too much and the connector popped off. I had to go get a new one with much difficulty.

Hi this wont work, I went through the exact same issue, and its impossible to attach the new screen properly. your best bet is to try and find a second hand screen via ebay. it has to have the "housing part with it. otherwise you are wasting your time. it cost me so much to fix mine as I ordered two screens in the end I could have bought a new phone on special....
Try Ebay, and make sure you see the one with the screen and front housing on, I am unable to port the correct link on here as I haven't made 10 posts yet.
Search for the following on ebay : Genuine Sony Ericsson Xperia V LT25i front+digitizer touch screen+LCD display
This should let you find the correct screen
Look at the picture you will see the side housing for the front is also installed, the one you have ordered is the incorrect one as its only the LCD and the Digitzer, without the front housing that it gets "glued" onto. You can see the main difference where the earpiece is its shown as black, hence the mesh is there. that would be the correct one to order. Unless you have the means of getting yours glued back on the same way as the factory, I see you will struggle to get it done otherwise.

[Q] Z1 Display broken -> Selfrepair

Hi guys!
As the Title says, my display is broken.
I dont know how it happend actually but there are cracks all over the place:silly:
The Screen (Display) itself works but the touchscreen is not working.
My Question is: Is it enough to buy just the Digitizer or should I replace the whole display.
The difference in terms of money to spend are pretty big.
I thought about something like this:
Screen: http://www.ebay.at/itm/Neu-Digitize...zer_Ersatzteile_Werkzeuge&hash=item3ce4df392d
Sealing: http://www.ebay.at/itm/Sony-Xperia-...zer_Ersatzteile_Werkzeuge&hash=item3f392ed01d

Is there anything else?

Yes and no...
If you manage to take it apart and it doesn't break you can use old parts.
Digutizer and glass are glued together and it could be problem to separate them.
Have that problem on XU so I'm quite sure you'll have it on Z/Z1/Z2

The glass + digitizer are dead. I wanted to replace them together.. The only thing I dont need is the LCD Display.

Oh...sorry...I was reading in the car...
I'm not sure for that...
Check YouTube and see, if they aren't glued together there's no reason why you shouldn't use old LCD..
If you can find it separate, of course...

my own exp on replacing:
z1 is one of the easiest phones to change LCD i think
just need a little notice and focus
here is the linked that i followed to replace my lcd :
https://www.youtube.com/watch?v=gVALfBNvpOA&noredirect=1
+ first dont forget not damaging the frame when opening the back glass. try putting the the blue thing in the second mic to open it.
+ try to do the replacement in a dust free room to avoid some problems.
+ clean the lcd back for sure bcoz just one little dust on back of display can make the display pressed( changes color to black ) when pushing the display a little bit hard.
+ as you are trying to install the new lcd ,for sure seal it tight,because you may see some light from the cracks( the issue i'm suffering from) .after replacing it push it for a little long to make the glue works good and avoid problems
+ when closing the phone again try to clean the camera lens and the camera glass on the back cover to avoid image quality loss
+ for sure glue around the camera and led flash so so so tight bcoz if the back glass dont fit well , the flash's light will cover the lens while trying to take pics with flash and the image will be a garbage . ( you can put a kind of black sheet or sth between the camera and lens to avoid this)
these were all my personal issues on replacement ..
hope you dont have them
hope it be helpful..

Replacing the screen of my Z1 (C6903) suggestion wanted

Hi everyone!
Today i visited the sony care point to discover that my phone isn't covered by warranty anymore, due to fact the internal LCD had a crack (despite never dropped in recent times).
Anyway, no worries... my warranty will end in a couple of days.
So... I want to attempt to fix it myself. I'm not experienced, but I work all day mounting PCs and servers, i think this will be a little diffent but not too hard, right?
Can anyone suggest me how and where to buy the entire frame and the LCD of the phone? (I want to keep it waterproof)
I saw many websites, but I don't trust most of them, so a good reccomendation is really useful here.
Also, what set of tools is reccomended to do everything? (Can i use my hair dryer to unglue the screen?)
Many thanks and sorry for my english being so bad, is not my native language.

I'm not sure how to replace the screen on the Z1, but I'd warn you against relying on its waterproofing after replacing the screen. Unless you can perfectly fit the rubber seal so there's literally no gap, the water will enter your phone.

It can be waterproof but don't buy cheap replacement as they are not always properly glued tohether, if at all. Buy original lcd+digitizer+frame assembly and precut glue frames like this. Hair dryer should be enough.

I cracked my screen yesterday
Today i get it from the technician (not original sony, in my country is inexistent). So far so good, only i found one problem (waterproof lost of course) the WIFI signal power is down by -20dB. So, now i have problems connecting to distants wifi.
EDIT: Now wifi working normal again, just another trip to the technician
Also, my phone is black front & withe back now.

yea i replaced my screen and i think it messes with my sensors, im not entirely sure im still doing some analysis but like after some time (about 2 hours or so) my gyro, light and proximity sensors stop working until reboot.
one more thing. theres layers of stuff inside of the z1, its a bit complicated, even for me and i am a computer & phone tec. its all about the glue and remembering where they go. i didnt really do mine correctly so i lost my waterproofing. gluing it 100% like stock is very hard.
ans ps
DONT USE A HAIR DRYER!!!
it wont get hot enough to separate the screen (broke a galaxy s3 back in the day doing that) use a heat gun
