[Q] Blinking and blue display - Desire Accessories

I wonder if anyone of you has experienced this kind of failure. 3 weeks ago I had an accident: my smartphone laying on car roo was crushed by trunk door after opening. Display had cracked, to my surprise digitizer survived. GSM service has replaced amoled screen and everything looked fine until yesterday, when it blinked couple time as if connection tape was not fit tightly.
It was this effect I recorded: youtube.com/watch?v=-lYj0nXc7NI
Today it happened again but after couple minutes of blinking it just got persistent blue shade. GMS service checked the tape and it was ok; they said either display is defective or motherboard is failing (I have to wait until they receive components delivery).
After an hour or so, I switched phone again and after a minute of blinking, it settled down and true colours returned. I suspected it was due to heat; i did a test running cpu benchmark and a game at the same time... in couple minutes it started blinking again and turned blue for another several minutes. I repeated this test once more with the same results. Does this mean main board is main suspect? I guess it was cracked slightly and when it is warmed up it there are electric disconnection of some kind... I just want to make sure GSM service will not extend unnecessary costs if I decide to repair it.
cheers,

Tu my surprise it was faulty display. Replaced with another AMOLED it turned to be perfectly fine.

Fixing proximity&ambient light sensor with heat gun

Hey everyone,
My issue with proximity sensor, was that is used to work very rarely. If it worked, everything was alright, but most of the time I had to switch screen off manually during a call, and it was hell of annoying. It was not software issue, because "Sensors sense" app clearly shown, that mos of the time proximity sensor simply did not work. It just kept on polling data from sensor, and no data did come at all.
Very similar situation happend with light sensor, but most of the time it kept on showing 10 lx, independantly on the amount of light recieved.
The result is simple - my quietly brilliant smartphone, lost some of its smartness...
I decided to disassembly my senny, it is not first time after changing digitizer and LED.
For the first time, two weeks ago I pointed heat gun at those sensors, being careful not to aim anything else. I used 270 Celcius degrees (tin melts in 230) for about a minute. For a week everything was almost as perfect as in a new phone. But later it stopped working.
So I thought more temperature is needed. And gave is 300 degrees. But nothing has changed. Right after fixing it worked, but now it is very moody.
What should I do, any ideas?
Thanks for anyadvices. Have a nice day.
From physics i guess wen u heat the phone some metal or wires expand making a connection. And maybe it takes abwt a week for the wires to cool down and contract and lose that contact. So my guess is to check if every connection is intact. Also may i noe how it is to change the lcd on the senny in ur country. Just wanna compare prices
Bump?

Xperia Z3 screen flickering, help

I gave my Z3 a little bath in tap water in the sink. It was not submerged so this is more like a shower. I double checked and secure the ports. I don't even use the ports anyway because I have magnetic charging. I dried it and started using it. It was all fine until 5 mins later it just randomly turned off. Battery was good, tried using the power button and it wouldn't work. So I did the power button and volume + method and it fixed it. But the touch screen didn't work sometimes (randomly), there was a blinking red light before I booted it on, and there is rattling near the camera area when i shake it. I ran diagnostics and noticed that my screen was also flickering. Some of the tests used vibration as feedback and this made the flickering worse. Now the screen is struggling to stay lit. It turns on for 3 seconds and then it dies. You can only see parts of it too. I need help. This phone is unusable. I bought this phone (Sony Xperia Z3 D6603 black) from Worldwide Distributors on Amazon.com 3 months ago. I only took it into the water a few times. I don't think its water damage because I had the flaps secured unless Sony gave me a defective phone. I paid $700 for this and I'm not rich either. I was saving up. The phone has the standard 2 year warranty. Somebody please help. what should I do? Will Sony fix it or give me a new one?
UPDATE: Screen is dead. It still turns on and touch screen still works but cant see anything. It's like it lost signal . Kinda like how a tv loses signal. The tv still works but are no shows on.
IMPORTANT: I just found a little hole that shows part of the screen backlight. Its on the side but its more like a crack. I haven't drop this or anything. So this is possibly how the water got in. This is also Sony's fault. Will I get a new replacement or refund or repair or something?
Thanks for all your help.

Happened to me too! The screen is black but is showing the brightness and the touch works. It's totally weird!. i'm going to send the phone to SAT
Seems the lcd backlight is still working where the lcd screen is not;
not sure whether the warranty covers water damage or not...
Got around the same problem. happend in the water screen went black phone was still working. After a lot of reboots and resets it started to work for around 3 seconds then evantually the screen was staying, but is flashing now, looks like the flickering happens when the screen gets too much power. In light conditions it either flickers or is real dark.
What can I do to fix this? Or do I just contact Sony? I've also tried the pressure test and it is water resistant so it has to be something different.
If the screen is cracked they will charge you for the replacement for sure

Hi. I've noticed that my screen flickers when I put the brightness on maximum. Watching the behavior it makes me think that it happens all the time, but it's only noticeable the screen brightness is high. Tried to get it on film, but my camera does not seem to pick up the flickering.
I noticed this after a pool bath with my phone, but i don't know if it is related to that. I did not a chance to use maximum brightness before
I do not have any other issues though, just the flickering. Should i send it to repair? My phone is an 6633 Dual Sim Z3 (Brazilian, unbranded) with less then 3 months of usage.

[Q] My display seems to fail randomly, even after changing LCD. What could it be?

So here's my issue. Yesterday, my phone started to give me a while screen full of dead pixels (pinkish color) randomly. I would turn off the phone, turn it back on and after 2-3 minutes it would crash again. Last year I dropped it and cracked the screen, so to me it was related to that. The phone works fine other than that (music plays when display fails. I did wipe it completely and reinstalled Kit Kat, it solved the issue temporarily but after 30 minutes it started again.
Today I decided to go check out a phone repair shop and ended getting my phone fixed by them. What this consisted of is a replacing the display and plastic frame. I picked up the phone and everything was perfect, new screen and display which looks and feels like new.
Now it's been about 5 hours and the phone started acting strange again. Now it's a lot less worse than before, but I still get the full screen of dead pixels. The display will go on and off (I guess it's trying to reinitialize or something) but always fails. So I end up rebooting the phone for it to work again.
The 2 times it happened after getting the phone fixed it was when I put it in my pocket to go from my work to my car, and then from my car to my home. So I don't know if it has anything to do with being in my pocket, that's why I came here.
So could anyone could shed some light on my issue here? Is my phone already dying? It's only been 13 months and I'd hate to have spent for a new display for basically nothing.
Replace the flex cable. If that doesn't work then it's an issue with the motherboard/screen, in which case you would have to guess between the two, or simply send it to LG and pay for a repair.

Grey Static/Snow on LCD

Hi,
I have a clients phone, They dropped it into water. Phone LCD worked fine, touch screen did not function correctly, and the bottom soft buttons were activating. making the phone unusable.
I orded a new screen, and decided to test it, before installing it. After removing the mid frame, I plugged in the LCD to find a strange grey snow pattern. I disconnected the battery, reseated and checked the LCD cable. I got the same pattern,
I was positive the new LCD is faulty, but not 100% sure now.
I reconnected the old screen and have a similar but not identical pattern. I can understand breaking the old LCD while taking it apart, or getting a faulty new LCD, just unlikely for both to happen.
Are there any other connections I should check. What do you guys think?

Possible display damage? Or proximity sensor issue?

Hi everybody.
I’ve had this phone for 10 months now and it’s been great. Yesterday, when i was trying to make a call, it was telling me that i am too close to the screen. I understood that the proximity sensor was acting funny, but I didn’t had time to look into it, because it was not covered by anything and it was in good light. This morning it was a short white flash when I unlocked it or when I was turning the screen off. It worked great all day after that. Then this evening i was using the phone and all of the sudden the screen started to flash white, then it would turn off fast and back on all white. It did that for 4-5 times, then it went in the state you see in the clip below. At one tine, it turned on like nothing happened for 3-4 seconds.
If i plug the charger in, it reacts normal. It's making the charging sound and it vibrates. Seems to be alive in the background, even though it's not displaying anything.
Does it have anything to do with the proximity sensor? Is it the ribbon cable connecting the display to the motherboard faulty? Should i just order a new display assembly?
Interesting, the next day seems to behave a bit different. I had remote erased it, i didn't want any of my personal data to remain on it.
I have found out that if the brightness level is low, i takes a few seconds until it starts blinking. If the brightness is high, then it does that straight away.
Ok, i will post a follow up for anyone else having the same problem. Now i can see that the display is damaged on the top left corner, the pixels are staying lit up bright. Now i can use it on low brightness for longer periods of time without flickering.
I have ordered a replacement screen assembly and i'm still waiting for it, as i don't have the phone under warranty. Looking forward to getting it fixed.
I have also ordered a replacement screen and will replace it when the shipment arrived. Have you found a repair manual for the screen replacement?
I have already removed the back cover of my phone and it seems it will not be so difficult. But it would be better to follow a manual.

I read this post now, I've got this kinda of broblem a month ago, but this happened only when the phone temperature became hot, I mean over 40°C, after a factory reset everything became normal, I no longer got high temperature and this problem don't appear, so at least in my phone it wasn't a hardware problem.

How was the teardown ? I can't find any videos on it. The axon 7 was a pain for me because the aluminum case was a pain to take off around the corners and got damaged a bit. Hopefully removing the back of the axon 10 is a little easier . Thanks for any info
