[Q] Tf300t black screen, does not power on - Transformer TF300T Q&A, Help & Troubleshooting

Hi guys,
some days ago I found that I couldn't turn my tf300t on. I thought the battery was low, but even after charging it for an entire night (the led on the power/lock button changed colour from orange to green, so it should be charged), if I press the power button nothing happens (black screen, no sound, dead!)
I tried to:
1) press the reset pin;
2) hold the power button pressed for more than 30 seconds;
3) remove the back cover and checked if the battery was correctly plugged in (everything seems at the proper place).
Is the tablet definitely dead or could I try something else?
Any suggestion is very appreciated.
Thanks in advance,
bye.

HTC 2125 white screen

Hi guys,
I have a problem with a friend's HTC 2125.
The phone are working fine and yesterday, i was shut down it and the simcard was removed.
Then, i try to turn on the phone and this one, launches a white screen (10-15 secondos ago).
I see this issue and try to launch the bootloader pressing the camera button and connecting the usb cable but this screen appear again. I try to launch the bootloader pressing the comm manager + camera button + power button and this screen appear again.
The white screen appear in the phone and is necesary to remove the battery because pressing the power off, this screen don't dissapear.
I try to charge the phone (this is shutdown, not in white screen) but when i insert the usb connector in the jack and the phone turn on and appear the white screen and the amber led don't turn on.
I compare these issues with my HTC 2125 and this works fine, the boot loader appear with the two combinations (3 seconds ago) and if i try to charge when the phone is off, this one turn on the amber led.
This is a hardware problem, have any solution, or the phone are wrong?
Thanks for you help!!!

Xoom is dead!

Hallo everyone,
I have a motorola Xoom wifi (mz604 i guess)... Once (almost 1 year ago) i installed the touch recovery and a ICS stock rooted rom.
It worked always fine.... today I went to check my email, and the xoom was off and i couldn't turn it on... I thought it was the battery, but when the battery is empty, when you try to turn the xoom on you see a red blinking led on the top (next to the front camera)...
But i put the xoom to charge, (the white led on the bottom went on) and when i came back home the led was green.
I tried to turn the xoom on, but surprise, nothing, no reaction, then y plugged the charger once again, and the bottom led went green, but i still can't turn the tablet on.
I tried all keys combinations that are possible.... Power + Volume up, Power + Volume down, Power + Volume Up and Down, Just volume down, Just volume Up, both volume keys...
Then i tried to connect the xoom to the PC, and also no reaction, nothing in the Device Manager.... (i have Windows 8)
Someone have an idea to solve this problem? Or is my tablet really dead?
Thank you very much.

Might sound a bit basic, but when you did the key combinations, did you hold the buttons down for 5-10 seconds? I think power plus volume up is reset button.

Murderer!!! JK
.....and you're making sure to press Volume up and then Power?
Hi Luinwethion,
My Xoom is in the same state you described. It happened this morning. There is a white light while charging and a green light after some time. I didn't get any response, with any keys combination.
Have you fixed yours?
Can you send me any tip to bring it to live again?
Thanks in advance.

Take the back cover off, on the bottom side of battery there are two wires-black&red- take them off the socket for 10minutes, when you connect it back again xoom should work!
Quick q: do you hear that click sound when pressing power button?
I have the same problem , my xoom went off without doing anything and it doesn't boot up!
does the disconnecting battery fix the problem ?
What rom you;

I'm in the same boat - the Xoom (USA WiFi) hung up while playing music - I rebooted it (power+up volume) it recovered, but then all the apps started crashing - I rebooted it again and it did not boot - just a blank screen. Battery light shows a charge when connected to a charger.
Does someone have instructions on how to remove the back cover?

It looks like the latest Google Play Services updated has dropped support for our Xoom's
Mine loads, then more GAPPS errors thank you can shake a stick it - if i let the screen time out following a forced reboot it doesnt come back on.

[Q] Post Screen Replacement - Weird Failed Boot up

Hey all, I have an Asus TF300T and recently replaced a cracked screen. I replaced with the same type - 69.10121.G01. Replacement went smoothly enough.
Once screen replacement was complete, I plugged in the charger - saw the Battery Icon on the screen confirm it was charging and the light on the power button stayed orange - until fully charged. Now the light is green.
Unfortunately,the tablet wont power up. I checked the on/off switch next to the power button. Checked all connections. Held power down, Pressed hard reset, etc. I read somewhere here that someone had success with Volume Down + Power - and after my 20th attempt at that, the ASUS recovery screen appeared for 2 seconds and then the screen went dark again.
So the screen/digitizer/lcd/whatever "works" but there is something amiss. Unfortunately, I am on a boat and cant get to another screen to try the HDMI cable on a TV or monitor. Any thoughts on what could be causing this or what might make this work again?
Thanks!

[Q] Phone Not Loading After Screen Replacement - Updated: Now Power Button

Hello,
Recently, my phone and I took a splash in a pool. I've never replaced a digitizer before, but since everything was still functioning perfectly fine except the screen, I ordered a Digitizer/LCD. Just finished installing and pieced everything together except the outer shell. Went to boot up, but nothing. I had a full battery before I disassembled it, but figured maybe I didn't connect the battery correctly. I hooked it to the charger and immediately got the "Alcatel One Touch 3 - Powered by Android" splash screen. Then it went to the battery charge icon, (the same that appears when the phone is charging by not on). Tried holding the power button again, but no response. Unplugged/plugged several times and even pulled the plug at the splash screen. Nothing.
I'm pretty certain everything is seated correctly, but does this point to one specific thing I didn't do correctly? Any help is very much appreciated. I've come this far and see the light but so disheartened.
Hello,
Just wanted to update: It's the Power Button. I was able to connect to the charger via a power strip, flipped the switch and jerry-rigged so I could toggle the volume buttons. Currently, the phone is in Android Recovery mode. I can scroll with the volume buttons, but I cannot select (the default language right now), because the Power Button isn't responding.
Anything I can do?
Edit: Looks like I may have snapped the power button ribbon

Black Screen and Not Powering On

Hi guys,
TLDR; Phone won't turn on, notification light flashes red once on power up (sometimes), black screen all the time. :crying:
So my brother has asked me to try and fix his Nexus 5 as he isn't tech savvy at all.
So the problem he is having started when he tried powering the phone on and it started to boot up and then started resetting iteself.
It now will not power on at all and doesn't seem to be on at all.
When holding the power button, it will sometimes flash the notification light (at the bottom) red for a second or two. No other response from the phone.
I've tried holding the power button for up to 5 minutes with nothing. I've tried holding the V+ key with the power button for a few seconds up to a few minutes then tried pressing the buttons expected to get to a reset menu with no indication of anything.
I'm kind of lost and was wondering if anyone has had these issues before and know what is the best issue to try and repair?
Thanks
It could be a faulty power button which is a common issue with the Nexus 5.
Remove the logic board, clean around the power button with isopropyl alcohol, dry it, quickly press and release the power button using more pressure than normal, re-install, and try to boot.
You could also try this: hold volume + button and connect the phone to a computer using a USB cable.
Thanks audit13, I'll give it a shot and shout back if it works
