If there is water in the display which has damaged something then no amount of flashing is going to help. Leave it a bowl of rice over night and if still doesn't power on then you'll need a service centre.

The phone is power on and everything fine even i can connect it to my pc led light also working illumination strip also very fine only display is showing nothing just black when touch the screen the sounds are hearable i dono wat happened since touch screen and everything working fine and i dont have warranty also bootloader unlocked
The LCD / LCD flex cable has been damaged or the part of the motherboard that controls the LCD. You would need to take it apart and look for corrosion on the motherboard and flex cable. It's possible leaving it open and letting it dry out might help. Liquid damage is unpredictable. If you don't see any signs of corrosion then you could buy a new LCD and give it a shot.

hey guys,
i just bought a broken atrix off ebay. i just got it in the mail and took it apart and the phone is missing the flex cable for the digitizer. so i ordered a new digitizer. i noticed its blinking red so im guessing its bricked? but the lcd lights up but nothing shows up. do i need to buy an lcd screen as well?
no one has any ideas at all?
The red light could just mean that the battery is going dead. Have you charged it?

battery still had charge, well at least that is what the guy told me. but wouldn't a logo or low battery symbol appear if that was the case? instead of the backlight turning on and black screen?
Well, could mean that the LCD is no good. Usually, if it is bricked it would show an error message. So, if nothing is being shown then it might be the display. I would put it on the charger regardless. Does the notification light go on when you plug it in while the phone is off? It should flash green and then either go to yellow or stay green.

Does the phone sync to your computer via USB? When putting in the motherboard angle the usb ports first so they are fully seated. Then make sure the bottom ribbon cable (LCD) is fully seated on the motherboard, you will have room to lift it up a little. Use a razor blade to push up on the cable to make sure it is fully seated and make sure you hear a snap when push down the board. Also screw down the backplate where the LCD ribbon is located. Then plug in the phone with the battery out. If it's bricked you will still get a failure to boot screen. There are also problems with the board that could cause video problems. It's best to have a few parts phones of the same model to find the real problem.

yeah the led turns green when i plug in the charger but i tried a hard reset (the vol down and power) the led flashes green but still get a blank black screen. i usually buy new parts all together just in case but the guy i bought it from said he tried to fix it himself but ended up ripping off the flex cable from the digitizer so i think the lcd is new as well. at least that is what i hope.

i know, i already disassembled the phone to assess the damage. is there a way to know if the lcd is damaged or faulty visually without being plugged into the phone?
Hey all, last week i got my LWW onto a washing machine, i realized this like 20 min after it started, so i inmediately took it out, and disassembled it.
Since then, ive tried almost everything, drying it with rice, brushing it with alcohol, direct heat from a heat blower, but i just cant get it to start.
At first it didnt do anything when i pressed the power button, after i rinsed it with alcohol, it started vibrating, led backlight turns on, then it gets a black screen. It gets into a loop, where the backlight led lits, then black screen, then nothing, then it starts all over again. I can get into flashmode, and even flash firmwares, i just cant get it to boot in normal mode. Oh, and theres no led indicator, no green, red nor blue. What could it be? anything software related or is it hardware related?

This should be hardware related, cause the water shoudn't have touched the software
Drying with rice was a good idea, I don't know what you could do apart from this. I think you will have to send it to service
Hardly will you be able to recover your phone with something related to Software. He must have come in games are probably shorting the motherboard. Tera in a leading specialized assistance.
Since i can go into flashmode, is there a way for me to somehow debug whats causing the problems, like a log like from the boot sequence, to narrow down the problem?? Is there any software that could help me achieve this?
Also, should the LWW start if i have the touchscreen cable detached? or does it need to have everything connected to propery start??

Hey guys,
Went to use my phone yesterday, never flashed or anything like that, and it just wouldn't respond. When I plug it in the sony logo flickers every 7 seconds and it won't respond to any button combination for rebooting. When it's not plugged in I can't get any sort of response.
Please tell me someone has encountered this before.
Same problem
Hi I have the same problem. Only is that the screen flickers every 0.5 seconds with SE logo.
I downloaded the repair tool but not abLe to process the repair on my phone. Nothing works. Opened the phone, removed the battery plug, tried to power on the phone without the battery plugged-in, nothing. Please help.
Sony repair wont help me. Apparently there is calcium on the magnetic ports or liquid damage in the phone; no liquid damage at all, phone was never put in water and nor any of the white stickers turned red.

Maybe due to corrupt software. Try flashing a new firmware using flashtool.
Hey guys, got some update from a repair center I usually deal with. It seems that the motherboard is dead. According to them, it seems that the battery might have been overheating and might have affect the motherboard. I'm going to try to call the sony mobile tech support and see if a repair mailer could be sent to me and going to keep you posted.
Cheers,

Damn... i also have to do it
I have tried this http://forum.xda-developers.com/xperia-z/help/hardware-fix-xperia-z-charging-booting-t2760911 bt it didnt work for me i hope it would work for u.
My friend got his new HTC Desire 826 in July 2015. He is having issue with his phone, the screen totally blackouts. He doesn't want to repair the phone because it has no more warranty and will cost much to repair. He asked my help to recover any data possible from his phone.
This was the info I got from him: The phone would restart itself once in a while in the recent few months of use (almost the time that the warranty ended). The screen would black out sometimes, a physical hit on the phone helped to recover it. At the last few moments before the screen totally blackout, the screen showed the mirror image of what it's suppose to show (he had to put it in front of a mirror to read the message). And then it just died and never come alive again. He can't remember whether he set the phone to silent mode.
What I did: Removed and put in the battery, pressing power button gives me a short vibration (I assume that means it can be turned on). Dissemble and reassembled the boards, flex cables etc. No burn mark or broken connection seen. Connect to TV using MHL cable, no signal detected. Soft reset by pressing POWER + VOLUME UP button, it vibrated and screen was still black. Since then, charging after turn on doesn't shows red light below the front camera. The metal cover above the motherboard was usually very hot whenever the phone is on. I'm working like I'm blind, omg >_<.
What's wrong with the phone? What should I do? Possible to repair? Some questions I'd like to ask.
1) Using MHL, does the phone screen need to be working then the TV will show what's on the phone screen?
2) Is there anyway I can connect the phone to other external screen and control externally?
3) I'm hesitant to repair the phone, the heating up of the motherboard scares me that the phone won't last long even after repair. Anyone has this phone and how do u go about this heating issue?
