Galaxy S4 Makes Siren Like Noise and Screen Won't Turn On

Hello,
Unfortunately I have dropped my Galaxy S4, however the screen did not shatter. It only has small scratches on it, however the screen does not work and it won't turn on. The phone turns on and the home, menu and back buttons work however the screen does not display anything and it seems to be unresponsive. Everyonce and a while, the phone also makes a really loud, siren like noise and vibrates. I am guesing that this might be because of the low battery. I would really apprecaite it if anyone could tell me what to do and if a screen replacement would work.

Problem with the backlight

Hi! Two days ago, my phone dropped in water , i put them immediately in rice until today. When start it with the power button, i felt the vibration and i hear the open sound. But the screen remains black... but i discover that it was just the backlight because when i watch the screen under a lamp i can see the interface and slide between pages... but its very dark. Is it possible to change this backlight? or just wait few other days to allow time to dry fully. I welcome your suggestions! thanks

When there's water involved, IT's hard to know exactly what damaged. Could be just stain on the ribbon connectors, a burned fuse/diode/resistor (all of them micro sized) etc.. or just the LCD's backlight damaged entirely.
Keep it on rice for more time. I would make the battery to discharge to 0%, But it's also more recommended to keep the phone OFF. Only my friend LUCK knows.
To change the backlight, the whole screen needs to be changed.

Backlight died on me. Possible moisture.
First, it was on boot loop (on stock rom)
i went to restart it (holding power button and volume down)
then the screen turned bright white, restarted it and then the backlight died, dismantled the phone, now still in rice, also happened on 2nd April.
Any help is greatly appreciated.

Took it apart down to the Screen (not the screen layers), left it in rice, works like a brand new now. Cheers.

I just replace all the frame and lcd for a new on my nexus 5, but the problem was still there... no backlight, i can see a little bit the screen, but it's very dark... do you have any idea for try to repair this, because now i don't think that it's the screen but more a motherboard or power problem for the backlight :S

exactly same problem here
nexus 5 phone dropped in water.
Backlight went out permanently - rice didn´t help.
Can see the display working using a flashlight - so rest of the phone seems to be working ok.
Just pruchased a new screen, put it all in and still the same problem: display works, touch works, backlight is off.
So it seems the backlight part of the display receives no power - anybody has an idea how to fix that?
thanks

I have answer to this!
I have had this problem like 3 months now and i finally fixed it.
Basically what i did was that i bought a broken nexus 5 (only the screen glass was broken) and tried to swap every part one by one. The one that was not working was the main dock!
It is a cheap fix, like 10£ on Ebay.
I am writing this post because anyone else haven't.
I hope that someone sees this.
I now copy this message to all other threads so people can fix their nexus 5's
PS:as you can probably tell English isn't my first language.

Hello! I am having the same problem. The cell phone fell to the floor and the next day the problem began. The display is not broken.
What are you taking about when you say "main dock"? Motherboard aka mainboard?
Thanks!

[q] nexus 5 screen snowflakes urgent

My nexus 5 broke down recently. I tried to turn it on, but the following image appears while booting up. The sounds and notifications work, but the screen doesn't. I dropped my phone accidentally, but then it worked for about a few minutes, and turn back to the snowflake screen. I have searched the web, but there are no answers. If anyone can help, that will be great. (I think its not the lcd)

Hey! I have the same problem here. Did you find the way to fix this?

Oneplus One black screen

Hello guys,
After a while I decided to change the screen of my opo because it was broken and i wanted to give it some use, so yesterday I got the screen that I bought and I changed it. It looked half light and the other half dark, like burned, so I decided to see if everything was well connected. It was all ok but I made sure everything was set correctly, but now when I turn it on, the screen lights up a few seconds and goes off, but the phone turns on, I can block, unlock the phone but I can't see anything. Any solution?
Thank you!
