TF700 Issue

Hey guys, I have a problem with my TF700
First of all my TF700 is rooted, but I didn't change the ROM or any of those advanced stuff.
My TF700 has a black screen problem...When I hit the power button the screen comes on but its black...as in the light is on but its a dim black light, you can't see anything but I can tell the tablet is on. When I press the power button again the dim light comes off.
When I try pressing the power button and the volume down button or any of those combinations the tablet just vibrates and turns off and the dim light comes back on with no display. I don't see any of the things that usually comes on when you press those combinations in order to cold boot the device.
When I plug in the charger, the charger light is green indicating that it is fully charged.
When I plug it in to my computer it says installation of driver failed, and it says no APX driver found.
Can someone help me please?

Get a proper HDMI cable and connect it to your TV's HDMI port and see if that will at least let you see what's going on.

Phone won't turn on

Hello guys, I have D6603 and tonight, phone gone dead... How it's happened... So, I was playing on phone and put phone in my pocket and stand up and phone felt from pocket and no reaction. I was thinking that display is broken.. but when try to make something, no reaction. I put it on charger (before drop it has 89% battery) and red light appear. I told WHY!? you have battery... after 10-15 sec, display light up and shows SONY, I told great, display is OK, but 1-2 sec after SONY logo, phone restart. NO VIBRATION, NO START UP, NOTHING.... when SONY logo disappear, red light gone for 5 sec, and then light up bright, after 10-15 sec red light dim and SONY logo appear, this is for 1 min and it stops, only red light... I left phone on charger, after about 30 minutes, red light turn off and nothing, phone won't turn on. I try Vol UP + power, yellow button, remove battery(when battery is not connect, it appear empty battery logo and 5 sec later phone restart, when connect battery again SONY logo for 2 sec and restart),nothing, no vibration... I try connect with PC, only fastboot work...

do the 20second reset. this simulates a battery pull.
i dropped my Z3 too, no damage at all, but it doesn't work at all anymore. No red lights nothing.

Dead phone, red charging light & start up screen loop after dropping it

After dropping my XZ on a table, it just went completly dead. The device switched off and wouldn't start again. So I tried to charge it, and hoped for the best, but when I connect it to a charger something strange occurs. The small red charging light comes on, and the black "SONY" text on a white background shows for a few seconds, then the device shuts off and the red light disappears. And from there on it just loops from black screen to red light -> sony logo -> black screen no red light -> red light -> sony logo -> black screen no red light and so on.
I've tried 2 different chargers (for several hours), tried starting it holding vol up and also starting it holding vol down. Tried connecting it to a computer with the xperia companion software, but it doesn't show any signs of connection. The SD card is removed.
I assume it has to be some kind of hardware issue (relating to the drop, yes i was drunk). But does anybody have experience from this problem and might advise what part is broken?

LG Q6 boot problem

Hi,
i have LG Q6, at the time it wont turn it on. When i turn on vibrates and show logo for 1/2 secund, than black and vibrate again in 10 sekunds. Than is black and again vibrate maybe on 20sec or 30sec.
If i plug in charger on vibrates once, than black and again like if i turn it on. I think that was dead battery and i replace it and same problem.
I hold voluime dome and power on to go in hard reset menu and if i choose yes, and one more time yes then phone turn off.
If i go in download mode i only see for 1/4 seconds ' download mode and than goes black and vibrates once.
if i go in safe mode pwr, after logo vol down - nothins happend, when turn on i just see logo for one second and than black, i press vol down when see logo but go black and vibrate once and thats all :/
What to do ?

Battery ded
It sounds like a damaged battery. Try changing it or leave it charging for a while. if it does not react then the battery has definitely died
Edit: I had not understood the part of the changed battery. You took it with a good technician or it just made him "like I change him"

My honor 4C doesn't charge and the led flashed Red Green Green 3 times but no power

When I connect it to the charger it glows red green green and repeats for 2 times after. If I connect it to the PC and turn it on, the PC makes a connected device sound but still it doesn't turn on. Anyone here knows what it is? Is it bricked?

No clue and found little on a Google search.
If you can easily disconnect the battery, try that.
Better if you can command it to do a hard reboot.
A hard reboot can sometimes resolve issues.
May be a hardware failure.
