[Q] Xperia T, black screen with LED blinking, nothing works, what can I do?

Hi! Sorry for my bad English.
My phone "died" while charging, but the notification LED is still blinking as the phone was just in a normal "stand by" status. Tried to call it from another phone, and it was offline.
This is the second time I get the black screen. It happened the first time 2/3 days ago, that time the phone was just sitting somewhere, then black screen, but the notification LED was blinking, so I tried to call it and it got stuck on the call ringing for like 10 minutes, then I found the reset thing on their site and it worked. This time it doesn't work. Also tried to connect it to a PC while holding the volume down button down, still didn't happen anything. Without holding the button down, nothing happens as well. PC Companion doesn't see it, Windows doesn't see any new device connected. The LED is still blinking. Didn't find anyone with the same problem, and those whith something similar to this, got it fixed with the reset buttons (like I did the first time) or had to send it in for repair... is there anything I can try before having to send it for assistance?
Both times, the LED is blinking blue, like a normal notification blinking, it was probably blinking this way because of an actual notification. It was at around 10/15% battery when i plugged it to the charger, and it was turned on. I didn't do anything to the phone since I bought it, I actually use it as it was a camera that can make phone calls and send messages, never connected to a PC.
I'd rather open it up and disconnect the battery (if that could help) than send it for assistance and maybe get it screwed even more or replaced with something worse...
Thank you!

Keep your xperia T on charger for 24 hours download the latest firmware for your phone and install it with the flashtool.

Thank you, rayenvs, but "nice" ways didn't work.
So I removed the cover and disconnected the battery, now it works again.

Xperia Z... freeze and brick?

Hey there,
So today I was using my Xperia Z aaaand bam, phone "died".
Battery was at that time 70%, phone was a little bit hot, but in scale of 1 to 10 it was like 6. I had not problems previously with it (besides broken screen that got replaced 3 weeks ago). I was playing a game then suddenly it got closed and my screen got shifted. Like Animation of horizontal menu stucked while going to vertical. I pressed power button many times, I've keept holding it for a short time, long time... nothing. Phone did not respond at all. After 10 minutes it went black. No idea if it went "sleep" or so since power button do not work again.
I tried to reset it with Power + Volume down, Power + Volume up and again, nothing.
I've tried factory reset with Sony Companion but no luck either. Phone is NOT detected by that program.
However, when I plug the phone to PC I hear sound that some device has been found. Phone is presented now as QHSUSB_DLOAD in device manager. I've heard that not a good sign...
When I plug it to PC or Charger nothing happens so I have no idea if phone is getting charged or not.
What even more confusing, when I press power button - nothing, phone is COLD. But when I press Power + Volume down after a while it starts to get warm, after a long time of repeating this really warm.
Any ideas what could I do?
Thanks!

You phone has locked or unlocked bootloader? If unlocked, give a try to enter Fastboot mode and flash any custom ROM

Connect to pc to back your data up. Also does the touchscreen work? And did you drop your phone or something else?

the touchscreen doesn't work
debugging mode is not activated, I cannot transfer my data to the pc.
I had the touchscreen bug for some time and suddenly, the screen did not turn on. The phone did not fall.

If it still under warranty i would send it to where you bought it. Even if you dont have warranty try it because the device should not be broken under normal use.

keep pressing the power button and when your phone vibrates try and hit restart. i know your screen is blacked out but if possible just try and locate. it happened with me too and thankfully my devices' screen recovered. the pop up comes just adjacent to the power button. first option will be your power off and then just below will be your restart.

I already tried
the phone reboots well but still black screen

Help my phone won't turn on

Hi,
This morning I woke up, my phone was locked on the screensaver, nothing was happening at all. So I har shut it down by keeping the power button pressed.
Since then, I can't turn it on anymore and it does basically nothing. I tried a hard reboot with power button and volume down (and tried also with volume up or both at the same time).
I also tried to plug it in the charger or in the computer but nothing happen at all.
I don't understand, it was working perfectly fine, I have no idea about what to do.
Thanks for any help.

Does it load the miui logo or it doesn't even light up at all?
If it doesn't turn on at all, then that has got to be a hardware issue and you gotta go for repair, if it does load the miui logo, then I can try and help you

Question Phone froze, powered off, and now unresponsive

Today I was in the car and using TeslAA Android Auto app on my Pixel 5a. At one point, the phone froze for a period and was unresponsive to any buttons. It then powered off, which I thought was restarting, but it never came back on. No matter what buttons I held down for how long, it was completely unresponsive. Nothing on the screen at all. I tried plugging it into my computer and when I held down the power button I could hear the USB sound on the computer. A long press (as if a hard reboot) would make it sound like I had unplugged the phone, and then pressing it again would sound like I plugged it back in. But still nothing on the screen. I have had zero issues with the phone up until now. What can I try?
I also tried power and volume down, but still nothing on the screen. It's like my screen completely died suddenly.

did you try power + vol down + vol up? all 3 at once for about 30 seconds then power on? that is a hard reset

Yeah I tried it all. I ended up realizing that for a problem like this, there's an additional year of warranty coverage, so I sent it into google for a free repair. So that was a nice surprise!
