Black screen - Google Pixel 4a Questions & Answers

Yesterday me Google Pixel 4a's screen went black, the screen was partly broken but it was working fine, now it just went black.
The power is on as I'm able to receive notifications and calls but the screen stays black. I tried to reboot it but doesn't work.
I suppose it is a hardware problem since the screen was broken but it is possible that I can use an external device as a screen just to get my data (or is there any software that can download the data from phone?)
Also it is possible to set up a new phone with the old one in this condition since fixing the screen is too expensive (~140€) and I'd rather buy a Pixel 6a

Screen is black

At work yesterday my phone was fine..I pulled it out of my pocket during a break and the screen wouldn't turn on..then I noticed the backlight was on and I can feel the screen vibrate when I hit where the home button should be but no picture. I am able to hear notifications and use my moto360 to make phone calls etc but no picture just a black screen and backlight is on.. Using my nexus 5 currently but wondering if anyone else has experienced this..T-Mobile said they would replace it under warranty.

Hello.
I have the exact same issue, I got a phone with a broken screen, it only had black backlight, then I changed the screen with a new one and still the same thing happens. Tried with two screens.
After replacing the screen I repaired the software via Sony PC companion, but it didn't work.
Does anyone know what the issue is here? Is it a dead motherboard or something else? Just so that I know to stop trying to fix it.
My unit isn't under warranty anymore because it had physical damage so replacing it via Sony is a no go.
The phone boots fine, I get audio reading of menu options for the initial setup, even the touch works, I can select options but I have no image, only the backlight.

[Q] Boot screen visible, but after boot - black screen

My daughter dropped her Nexus 5, which had been upgraded to Lollipop. She had her protective cover on it, and from the outside, nothing seems broken. When we turn it on, we see the white Google letters appear, then the android animation with the flying colorful dots (flying agonizingly slow), and then the phone builds the colorful android letters - again very slowly. All of that takes about a full minute. Then the phone seems fully booted (we hear the notification sounds), but the screen just goes and stays black. I can also get in bootloader and the screen works perfectly there too.
Does anybody have any idea about what could be wrong with it?
Also - I never rooted the phone, nor activated the usb debugging. Does anybody have any idea about how I might still be able to do that? And also - is there any way to back up personal data (like pictures) first?
Thanks!
Well it can't be a hardware fault surely.
You could try and get an adaptor to see if it will display an output on the TV. If you can do that, you may be able to backup the data. Although then again it may just be a waste of money. Does it show up as a device in windows?

[Q] Nexus 5 display corrupts after boot

My Nexus has a display problem and i'm trying to troubleshoot what the issue is and I'm wondering if anyone could help as it's not obvious where the issue lies.
What happened is I was using it as normal this morning and then the screen started flickering to different sizes/colours until it finally just went off. It was almost like it is trying to find the correct refresh rate and the colours appeared polarised at one point. After holding power down to reset it, the google logo appeared and then the spinning dots. Once the boot was complete the android logo appeared and then as soon as the main screen was displayed the display cuts off with a white pixelated mist and shuts off. The phone is still running as if I connect via HDMI I can see everything as normal however the phone responds extremely slowly. I can get into recovery however the screen quickly does some strange things, it flips like a mirror and cuts 1/3 of the screen off.
I'm not sure if this is a LCD problem as its a replacement from ebay that I've been using for a few weeks now. I would suspect that before anything else however it's odd the pre boot logos display fine. I've checked and cleaned all connections however it's still doing it. I'm running stock 5.1.1 rooted.

help my nexus 5
Could you see images on the old screen?
Hey! The display probably isn't the problem. It may actually be the battery not being able to supply power to the screen by being burned out. Try replacing the battery then take it to your local carriers store
Don't think it is the battery if the phone functions other than the display.
I have changed the screen on roughly 10 nexus 5 phones and, even with a so-so battery would boot the phone no display an image.
did you find a fix for your problem? I'm having the same issue. Everything works, I can hear sounds, notifications, receive calls but cannot see anything

SM-N915T green screen and then bootloop

So my T-Mobile Galaxy Note Edge (SM-N915T) running rooted Android 5.1.1 just encountered the infamous green screen seen. The first time, the green screen disappeared after entering sleep mode and waking up, then about 5 minutes later, the green screen stayed, even after a full reboot (even the Samsung bootup animation, download mode, and TWRP were tinted, so I think we can rule out software issue). The phone was still navigable and usable, just with a serious heavy green tint, curiously, the phone would change between the heavy green tint and a grey tint, and the tint would stay on the upper 30% of the phone and turn grey as it entered sleep mode, almost as if the phone was trying to correct the display or something was barely making contact inside the phone.
Then the green tint got more intense, I could make out the basic background, the fingerprint scanner let me past the lockscreen, and the S-Pen sounds would still play when the S-Pen was removed, inserted, and when the screen was touched. Additionally, my PC does not pick up the Note Edge, yes I have the Windows drivers installed, USB debugging enabled, and MTP + ADB enabled via the secret menu in the dialer. Also OTG is down, my mouse and keyboard are receiving power, but no longer recognized.
Now, after another reboot, the phone is stuck in a bootloop, with the Samsung and T-Mobile sounds playing over and over again, there is a green tint when the Samsung logo should be playing, but a dark screen (as in, AMOLED off) when the T-Mobile animation should be playing.
The phone can't even properly boot into download or recovery mode anymore.
The phone wasn't exposed to heat or pressure, it was just charging off an ASUS power brick and a LG microUSB cable (and was relatively cool, not hot).
The phone was bought second hand, KNOX is tripped, and well past the warranty period.
So my questions for everyone here:
-Any idea what the problem is? GPU failure? Bad solder? Short circuit? Screen failure?
-Any hope? I heard someone else was able to get rid of the green screen after freezing the phone, but at the same time, I don't want to risk condensation inside the phone if I don't have to, and if it was melted solder from some sort of charging issue, heating the phone would probably be a better solution.
While I do have backup phones and and a backup of all my files in case something like this happened, I'm going to miss the curved edge and the S-Pen, and I don't want to take the phone to a 3rd party repair shop, considering you can buy an used functional Note Edge for less than the price of a replacement display, besides, the new Note 7 looks nice.
Anything that hasn't been mentioned above would be helpful... Thanks
UPDATE:
Now the screen doesn't turn on anymore, it flashes green when turned on, but remains dead. The T-Mobile sound still plays, and the motor rumbles for a second, but the fingerprint scanner and S-Pen rumbles and sounds are no longer responsive notification light pulses between white and blue.
Attempting to boot into download or recovery mode yields 2 seconds of green screen, then the T-Mobile boot up sound.
UPDATE 2:
Phone boots properly now judging by the fingerprint scanner responding and S-Pen sound, touch screen also seems to be functional based on S-pen cancel sound, but screen is now completely black, is it safe to assume a screen failure/damage?
