Help with lifeless z1! - Xperia Z1 Q&A, Help & Troubleshooting

Hey guys,
Over a year ago the screen on my Z1 broke. It wasn't until two weeks ago that finally bought a new screen. The phone has been powered off for over a year. Once I installed the new screen and tried to power it back on I got no response. Just a constant red light led. I have left it charging over night on a number of occasions and nothing! Holding down the power button does nothing, holding the power + volume makes the red light flash twice, with no vibrations.
Any advice on what I should do would be much appreciated!

[Q] HTC One Wont Turn On - Bricked?

Hi Everyone,
I haven't been on here for a while. I have a HTC one that has stopped working. It is flashing the home and back buttons when I try to power it up and the LED light isn't working when I plug it in.
I Have managed to mess around enough with it trying the bright light trick and all combinations of power + volume down/up buttons to try and get it to spring into life. Iv e tried these connected to a charger and connected to the laptop as well.
When I press the volume down button and hold it the LED came on and started to flash, then it became constant red. I've left it charging overnight and its now a constant green so fully charged or so it thinks. Ive since tried the combination of buttons again but when I do the led goes off.
Ive scoured the internet last night for anyone with my similar situation and found a lot of posts but none that match my situation exactly.
When I turn it on normally nothing happens apart from the on sound and the under device manager it says "HTC MTP Device".
I m going to make a quick vid and put it on youtube and add the link in here just in case anyone has been in this situation before and found a remedy.
Before anyone asks I don't know what rom was on it, or if it was unlocked bootloader. I bought it second hand and just started using it. It went off mid day with plenty of battery and it wasn't hot.
Any help would be most appreciated as im running out of ideas fast!. plus my fingers are sore...lol.
Thanks for reading

[Q] Htc one m7 black screen, green LED, constant vibration

Evening all. I'm new to these forums so please bear with me regarding technical terms and such, but this is a pretty urgent problem and any/all help would be greatly appreciated.
I went for a jog about an hour ago leaving my phone in the house and upon my return I tried to power on the screen and the only response I got was a vibration and a continuous Green LED showing.
Its a while on now and my phones screen is black and won't respond to the power button, and every 12 seconds it produces a vibration along with the greeen LED which only goes away a second or two before the next buzz. What do I do?

have you tried shining a bright light, like another led / flash on the back of another phone, into your phones light sensor whilst holding down the power button, this is a common problem with these phones, the light sense is the 2 dots on the left at the top of the phone.

I tried that and we get to the screen when you first turn it on and then it goes back to before

try holding down power and volume down button at the same time to enter the bootloader. If that works then select factory reset using volume buttons and power buttons.

[Q] I9305 weird problem

Hi guys,
I hope you're all well.
I recently opened up my i9305 to remove a buggy power button whilst at it I was looking at the vibration motor. I reassembled it, placed it on charge. And it didn't respond instantly as usual, after a few minutes the red led light turns on but nothing else? What's weird is that when I press the home button the red led light will disappear for a few moments and then reappear. There's no way I can turn it on because I've got no power button, no splash screen comes up whilst charging.
Does anybody know what's going on? I'd appreciate any help

Dropped and broke

Well a couple of days ago I was being dumb and swinging on some a construction thing and my phone fell out of my pocket about 3 feet off the ground. Well it landed on it's face and I picked it up thanking god my screen didn't shatter but I clicked the power button and it was all white with some vertical green lines. After about 5 seconds the screen goes black and my phone is just dead. I have no idea what's wrong with it but when I hold the power button when it is plugged in the home and back arrow flashes and the phone vibrates. It also does this if I hold the Power and Volume button but nothing happens on the screen. I need help diagnosing this to see if it is an LCD problem so maybe i can just get that replaced instead of the whole phone. Also, the first time I plugged my phone in to the computer HTC manager popped up but now it just wouldn't detect it. Help please!

Note 5 Dead

My Note 5 has suddenly stopped working. I get a blue breathing light at the top, as well as a red one and at times no light. I have tried Volume Down + Power for 20-30 seconds, tried Volume Down + Home + Power and Volume Up + Home + Power... nothing whatsoever on the screen
Your display has deceased. I have the same problem and I will change the display to fix it
:| why this problem appear?(what did you do before it happen)
Last resort, Odin it.
Nothing was done... just woke up one morning with it dead. I have nothing whatsoever on the screen... I can get it picked up by ODIN but when I start the flashing process it doesn't do anything... just hangs there.
