Shuts down by itself

Ok so i was wrong, it doesn't shut off, it goes past the green windows mobile screen, then past the t-mobile shadow screen, then just sits there with a black screen, the power lights are on, but just stays black forever
One other note is a hard reset isn't possible it seems because the phone cannot be turned off
If the battery is removed it shuts off of course, but when its put back in it just starts up and apparently thats not good enough to do the hard reset because it just boots up like normal to the black screen

Try pressing the hard reset keys as you place the battery in. You might need someone else to put the battery in while you press the keys. If that seems tedious or doesn't work, try starting with bootloader buttons (Camera and power button at the same time). Then connect it to your computer and run T-Mobile's update.
Hopefully, that should work.

Black Screen, 5 vibrates, and LED lights on

This phone just broke after 3 months of use. Since I brought it off of amazon as unlocked, I do not have warranty on phone. The phone was not dropped nor water-damaged. It was sitting on the table and suddenly experiencing problems with lag. I proceed to turn off and try to restart phone.
The phone does not boot when I press the power button.
What I've tried:
case 1: I removed SD card, removed battery and removed USB cord. Press power button for 10 seconds. Put back battery and press power button
result 1: LED light on. The phone vibrates 5 times. Remains in black screen
case 2: I called my phone number from another phone
result 2: Straight to voice mail. This indicates the software did not even boot up. Hardware display is not the issue here. Most likely a Software issue.
case 3: I hold volume down key and power key to attempt hard-reset
result 3: LED light on. The phone vibrates 5 times. Remains in black screen
Since I routinely backed up my phone data. Last time I've checked (~4 days ago), the SD card was not nearly full. It was approximately 25% used space.
PLEASE HELP!! YOUR HELP WILL BE APPRECIATED!

Are you able to access any of the service menu's such as bootloader or fastboot mode?
If your not aware what those are, there are many references in this forum for you to find information.

No. The screen was all black. But fortunately, the phone was able to turn on after some trial and error.
You remove the battery and USB cord. Then while pressing (and holding) the home button key, you put back in the battery and press the power button. To hard reset, you must press volume down key, home key, and power key at the same time.

Glad that you got your phone working!
Mine continues to remain dead

I had this problem a few months back at first i too thought the phone was dead - but it did make boot vibration noise - but the screen would always remain "black" but after some time and after going into a very dark room i was able to see that the screen was not black, but that the backlight went out on it -- after having my screen replaced the phone now works fine - think i was using cm7 at the time.. hope this might help

Thanks for this tip! I'll check on the phone I had as well. I got to get it back from my buddy.

S5 Neo, screen goes black.

Hey!
I have an S5 Neo at work, and earlier on Friday morning it worked great, but then the screen started to go black, first it was only random and it would go back on again. But soon i had to try remove the battery and restart it, but nothing happend. After waiting some time the screen was back on again.
So when I got home I tried my best and got the screen working, did a backup and factory reset. I was super happy and tought that it had helped, because the screen come on right away. But as soon as I put the backcover on the screen started to flicker and then turned all black again.
I managed to get it working by pressing quite hard from the rear around the camera and the simcard holder. But only temporarily.
One other thing that does seem to work is to remove the battery, hold the power button pressed for some time and then start it back up, but as soon as i press in the upper corners the screen flickers, and if i press pretty much straight on the samsung logo it goes completly black and wont turn on, until I have had the phone turned off and pressed the power button for some time.
I understand that this must be something wrong with the display assembly(loose flex or solder joint in flex) or maybe even motherboard, is there anything I could try and do at home, or is my only option to send it away and get it fixed?

Black Screen Of Death!!! HELP!!!!

i have my phone for almost 7 months already. my phone went black and it wouldnt charge nor turn on. it wouldnt also turn on the LED blue light. been doing all the tips i can do. dont know if my phone is dead nor anything. cant feel no vibrate nor anything at all. i think my phone is dead dead. can you guys please help me. i got important phone calls and everything that i need to get it done. let me know asap. thanks!!!

If it doesn't charge, won't turn on, and doesn't vibrate, sounds like it's dead! Get in touch with Samsung about a replacement

Try a wireless charger

if you can charge it, can you get into download or recovery mode using button combinations?

Have you really tried *all* the possible 'tricks'? I remember the exact situation you just described happened to me a couple months ago. I left my phone charging overnight and when I woke the phone did not respond at all to any button smashing or resetting etc.. so what I did was, hold down the power button, Bixby button (not sure if that was necessary at all), and the volume *down* button all the same time (like you would press ctrl + alt + delete on a keyboard). I held it for 10+ seconds and at last my phone entered the recovery mode set-up which prompted me to press the volume down button once again to restart the phone. If you haven't tried this, give it a go!
