S5 Neo, screen goes black. - Galaxy S 5 Q&A, Help & Troubleshooting

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?

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.

Mirror Inverted Display on my HTC Touch

Hi friends..
I have a very strange problem which cropped up yesterday night, we guys had gone for a movie and my phone was in my pocket only, then coming back it started to rain and i still didn't take it out, but after i took it out in room i saw suddenly the screen going blank and so many white and blue lines started coming and it started flickering very badly! finally the display got mirror inverted! it still responds to touches at the right places but the display which i get is upside down and mirrored so can't read a thing!
i think some how a water droplet had gone inside and did something, i took out the battery and dried it under the fan too but still no change, now when i keep it on stand by and resume by short pressing power button for a second the proper screen comes and then it inverts again! please help me out if you've encountered such situation before..
i know we can turn the display upside down but this one is mirrored too, and it all happened after the screen flicker..
hav tried hard resetting ur mobile
Some Sony Ericsson mobiles had a similar problem, only way to repair it was display replacement.
How to Hard Reset?
hi friends, i read on another forums too that hardresetting is one way, so i turned the phone off
removed the battery for 5-10 seconds
replaced the battery
pressed the green and red buttons which are on the left and right of d pad
together i pressed the reset button which is to right of the usb socket,
and nothing happened! i kept pressing it for 10 seconds, and no screen popped up, when i removed the buttons it just restarted, without any screen showing that a hard reset has been desired and no change had happened..
Am i hard resetting it the right way?
ur mobile shouldnt be off while doing the above steps. After doing tat ur mobile will restart showing an warning press the action key and continue.

Click to expand...
Click to collapse
Device must be off. Hold red button, green button and reset. If it doesn't work, press Power. After a while white letters on black screen should appear, then press d-pad and wait about 5 minutes. You'll see a new message for a moment and Windows Mobile will start.
No change after hard reset
hi friends, i got a video on youtube demonstrating me how to do a hard reset, i did it and got the warning message too and it got reset, restoring the original settings. Still the screen remains it's own inverted self!
Any suggestions what can i do next? what can actually the problem be?
i'm taking it for service centre tomorrow. Wish me luck any ways

phone keeps turning off

V this is what i figured out V
okay so i realized its caused by the screen being turned off for more than a few seconds, whether it be from locking the phone, or the screen timing out. it causes the phone to power off (im not sure if it powers off or not, but the screen never comes back on once this happens) i try to unlock the phone, or hold down the power button, press the screen and all the hard buttons, nothing responds, i have to remove the battery from the back and put it back in to turn it back on...
Take out the battery for a day and leave it out then put it back in. See if that helps.

[Q] samsung s7390 went black then white then dead

I have a Samsung GT-S7390 phone. And now it seams dead. This is what happened.
I was using Google play to install Badoo and suddenly the screen went black and then gradually turned to completely white. It was unresponsive. No reaction on holding power button, or home button for a short or long time.
I didn't know how to turn it off and I didn't know a combination for a reset. So I pressed power, home and volume down buttons at the same time. The phone turned off and since then it is dead.
I tried to take out the battery for some time, take out sim card, tried all the combinations of buttons and did nothing. It is dead.
Does anyone knows what might happen to it?
Any answer is better then no answer. Please help.
Thanks!

Problem with a friends S5. The screen keeps going out.

When I turn the phone on the screen lights up for about a half a second and show the logo. The phone fully boots and all buttons work. When I push the power button to turn the screen on it does the same thing. I can see that its at the home screen. There is no water damage and the phone hasn't been dropped. Sometimes I can get it to boot up with the screen working right. Is this a common problem? What is the cause of this, bad screen, mainboard, software?
Thanks
