[Q] S4 mini white screen only help please - Galaxy S 4 Mini Q&A, Help & Troubleshooting

A few days ago my s4 mini fell in the toilet. I cleaned it put it in rice for 26 hours~ and also dissasembled it and blew the screen with a hair dryer. Now when I power it up it shows the logo s4 mini etc. etc. but instead of the samsung logo with the noise i get a white screen. After a while when it boots up it is still white but I can unlock it i hear the sound etc. Before that white screen i was stuck with a light blue one. Upon plugging in the charger i got solid 5 minute of "fixed" display (grayer colours, broken full brightness etc.). I ran the diagnostics test which is *#0*# I tested the colours and i found the red pixels turned to pink like red and the blue turned to purple. After a while it was quite hot and i lost that window of accessibility as the screen got stuck with a white display as mentioned above. My question is is there anyway to fix this without buying a new screen panel (which costs 85$ for my colour) or the only way is paying for the full service by Samsung?

Hi Costas,
The problem you have is called „ water damage“. All what you have done is not bad except that you shouldn't power it on. But look on the youtube how to handle phone with water damage or to bring it disassambled to some smart phone repair shop who is specialized in fixing the phones with water damege. It's not enough just to dry the components and fire it up becouse the chlor from the water make conections which you can't see by „naked eye“ and there for is washing in other chemicals neccecery to „TRY“ to save your water damaged phone. And even after this threatment there is no garantee that the phone will working as before if water have reached places which are difficult to clean. So, it's not helpful to say anything about your phone esspecially becose you have swiched it on. Succes !

First error, put your phone in rice, really that only works for youtubers.
As boombastical said, you need to remove all remaining conductive and corrosive components that were dissolved in the water

[Q] Back light only comes on after replacing LCD and Digitizer

Hello, and I appreciate everyone who has taken a look at this post.
I recently replaced my LCD and Digitizer. A couple of months ago I dropped my phone into the bilge(bottom of a boat) filled with oil. When this happened the digitizer had a crack in the corner and the LCD got flooded with oil, not to mention the phone. I took of the back cover and let the oil drain out. I didn't open up the housing or anything. I soaked up as much oil as possible. Still though, half of the screen was a few shades darker and difficult to read text messages and playing games were out of the question. Everything else was fine, the OS didn't slow down and I saw no signs of rust anywhere.
During the holidays, I got the digitizer and LCD. So I followed the video on youtube from this website on how to take apart the Xperia Play. I replaced the LCD and I used the same adhesive strip over again with the digitizer. Now when I turn on my phone, it vibrates, but the back light comes on periodically for about 2-3 seconds and then turns of. And then a few minutes later the back light will turn on and turn off again. i get no picture from the LCD. I have turned it off and on a few times. Same thing. I have also tried turning it on while holding the power button and random combinations of the other buttons. I plugged it into my pc and when the back light goes off, my computer detects a device but shortly after losses it.
I have read through other threads to see for similar stories. The only thing i can think of is maybe, I damaged the strip of the LCD or i fried my mother board. I just would like to know if it is another problem or if anyone has some good solutions for this.
If anyone can help me, it would be greatly appreciated. I love this phone and this n00b needs some help. Lol.
If it was just oil you dropped it in then the electronics will probably be fine as it is non conductive so the problem probably lies somewhere else. I do many phone repairs, mainly to iPhones, HTC's etc, but I have never done an XP so not too sure on specifics but what you describe would probably be ribbon cable related, either not a perfect connection or slightly damaged. It only takes a slight nick on the ribbon to render it useless. I replaced a digitizer on an HTC sensation once and the phone did exactly the same as what you describe. I took the new one off and put the old cracked one back on and the phone was normal again.
Dunno how much that helps but hope it's of some use

Help screen problem.Pure Alcohol spilt

Hello everyone you kind assistance is needed
Here is the problem I accidentally spilt lots of Alcohol(the kind you use to disinfect a wound or something) on my HOX.
Now the screen is bright white in one section and sort of grey on large part on the botom of the screen.
The phone appart from that works fine.
My intial though was to turn it off pluged it for charging leave it and hope for the alcohol to evaporate.
I plan to leave at that for like at least half a day.
Is there is something else you can propose?
In case it proves to be a hardware problem and I have to replace the screen can you give me an estimate of the screen price?
By the way I am in Greece.

[Q] Screen green tint 2 days after water damage

Found some similar issue threads but no clear resolution. Wanted to see if anyone here has been able to revive the screen on Note 2.
I dropped the phone in kitchen sink for a few seconds, it was only 1/4 (top part) submerged in dish water. Got the phone dried and kept in rice for about a day. The phone worked great (screen was normal) for 24 hours after the waterboarding incident. Then next afternoon, after I finished a call in bright sunlight, the phone screen went totally dark. I tried to reset it, pulled battery and restarted. Same issue.
The boot animation with the SAMSUNG logo is in the same tint. it is readable since it is bright white but still dark green. Tried putting it back in rice, then put it in the sun for couple of hours with the back opened. Still same issue.
Any thoughts on how / what to clean connectors wise? In the past I have destroyed a Galaxy S3 trying to replace a cracked front glass so my past is sketchy in self repair of phones though I have repaired a couple of tablets perfectly. That's neither here nor there.
Anyway... any step by step instructions or pointers in repairing this issue is appreciated. Thanks in advance for help rendered.
Regards,
Dan
I'm no expert, but I don't see how that's fixable without replacing the screen. For that I would look to YouTube for a video tutorial.

[Q] G3 virtually unharmed after dropping, but screen won't turn on

So while walking downstairs to my basement, I tried to put my phone back into my pocket and it slipped and dropped on the hard floor. It dropped about 4 ft and it had a hard plastic case around it (one of the Korean model cases with the small section exposed though). The glass screen protector I had on it cracked, but the actual screen is fine. I tried turning the phone back on, but only the notification light comes on and it keeps blinking green and blue.
EDIT: So I guess the LCD is broken cause the digitizer is completely intact and there's no indication that the phone was even dropped. Usually its the other way around.....

Do you have any new updates regarding your phone problem?

The only new thing that I discovered was that the backlight is probably broken. I can see a very faint image of the LG boot logo and the carrier logo when the phone boots up, but it just hangs there and the LED keeps blinking till the battery runs out/is taken out so I don't know what else is up.

No cracks at all. The only crack I had was on my tempered glass screen protector. I thought it was the actual screen, but I took it off and the screen was unscathed.

Take it back to and tell them that the phone just stopped working. I'm sure they will fix it under warranty.

Ghost touching + Black screen

Dear valued XDA members
Greetings...
My Xiaomi Note 5 screen broke a year ago; I just woke up and found out:
- The screen is flickering
- Ghost touching
- Colored lines appeared
- Eventually everything went into black
Today I decided to repair it... A brand new original screen; so I went to the repair center and the guy changed my screen infront of my eyes.
When I got back to home, ghost touching happened again in a crazy way, I can't use the phone at all, moreover after reboot the screen became black, I can hear sound only.
I am not sure what is causing this, since the screen is new, and the software is fine.
Anybody has a clue what is this?????
I added photos of the broken screen, and a video after it was replaced.
Thanks in advance
Bad cable, connector, or pins not properly seated.
Loose ground. Failed mobo.
Try a hard reboot if you haven't already. Take it back to the tech, they may have a better plan.
