Display issue-purple color instead of white (while trying to fix power button)

Hello,
I've had a power button issue on my Captivate. It's not physically stuck, but the device is functioning as if the power button is constantly pushed (turns on when battery is inserted, does not lock/unlock when pushed, etc). I did what worked for most people-took the phone apart (up to taking the motherboard off) and cleaned the button with rubbing alcohol. Once I put it back together (the power button still had the same issue), the phone started booting and everything that is supposed to be white is now purple. I checked the contacts between the LCD ribbon cable and motherboard, everything seems to be clean and nothing looks bent or out of shape.
Any advice?

it seems likely that some of the alcohol carrying water, possibly with some debris from your power button, got onto the cable contacts or on the gpu and created a short.
if you used rubbing alcohol, which is 30% water, then you may have some residual moisture. for this, take out the battery and put the phone in a bag of uncooked rice for a couple of days to wick moisture.
next time, use 100% isopropyl or use denatured ethanol.
you could also try gently blasting with dry air cleaner (in an aerosol can).
lastly, you could try tuning the color driver settings, more green, less red and blue, if the above doesn't work

Oh, I didn't even think about the fact that rubbing alcohol can cause this. I might as well get high quality electronics cleaner or something to be sure.
Thanks! :good: That might help with fixing the button as well.

[Q] Help: water damage from back glass. Red led on/off every 15", won't turnon

What led to the brick:
Submerged in water with flaps closed for a few seconds, as usual.
- camera showed moist
- removed the device immediately from water, then it switched off a few seconds later while drying it
- none of the button combinations do anything
- if plugged to charger red led comes on for 1 or 2 seconds and goes off
- if plugged to PC; led goes on for 1 or 2 seconds + USB device plugged in sound
- after red led goes on every 15" + USB device not recognized sound
- After some research it became obvious that water came trough the back panel, which is lifted
My biggest concern is to recover my data in the internal memory and of course getting the phone back to life, but all the pictures on there are worth 200 of this not so waterproof phone.
Do you think there is anything that can be done in this sense?
Thank you in advance for your answers.

Honestly, I don't think you can do anything.
You can try putting your phone in a bag of rice for at least a week with all flaps open to absorb the moisture.
Most importantly, do not try to turn it on or connect it to a power source again until you have tried to thoroughly dry it with the above method. Water + electricity = bad things for the internal components of your phone. You probably already fried several of them by powering the phone up while water was inside, in which case, your phone is dead and your data gone.

[Q] What To Do When Water Condenses Inside The Lens[SOLVED]

Our Sony has wonderful water resistance properties, but sony doesn't mention the second way by which water can enter the phone.
I live in a tropical area where the sea is nearby, so humidity stays at a staggering 80% and above. This humidity is present inside the phone as well.
Now the phone gets super heated when using the camera (4k, [email protected], [email protected], normal 1080p also gets heated but slowly).
Now when we use the phone in this condition in a pool, ocean, condensation occurs where droplets form inside the phone.
My keys (power, vol up/down, camera) went bizerk. And upon checking the lens there was fog inside.
I tried many sol, won't go through it now (waste of time).
What I did was,
1- Switched off the phone
2- Opened the ports, removes sim tray, mmc.
3- Took a hair dryer, directed towards the sim slot an min settings and at a distance of 15cm for 2/3 minutes (let the phones body heat up slowly and reach a high temperature, do not put the hair dryer too close so that it heats up quickly)
4- Quickly put the phone in a rice bag, IN A SLANTED POSITION (important) so that the sim slot faces up and in a slanting position.
5- Repeat step 3 & 4 for some time and voila the mist disappears.

Water damaged, only red led on AC

Hi all, my z3 compact has been damaged by water.
I opened it and let it dry.
But now it seems dead.
I am not able to turn it on at all: no boot, no screen on, no vibration and no led with power button ( also tried the power button + vol +/-)
When connected to the charger: only the red led stays on but no boot, no screen on and no vibration with power button.
Any advice to repair my phone?
Maybe have to replace the battery? Or disconnect and reconnect the battery?
Thank you for advices

Unfortunately non of those will fix Your problem. First You should disassemble Your phone, take out motherboard, take off alu shields from motherboard and clean whole motherboard with isopropyl alcohol. After that you can try to charge battery but if there is some short circuit on motherboard made by water damage charging Your phone without cleaning motherboard can damage it completely.

Ok, thank you for your advice

Is it possible to check my battery with an ohmmeter or ampermeter? If yes, what are the results for a healthy battery?

Sorry to hear that, i also experienced the same water issue. It was my first xperia, Z. I did the same thing, disassembled completely every detachable components, let them dry and clean but still dead. You will have to find a spare working motherboard, maybe you can still use some components -if working- like batter, speaker, buttons.... i found an old one (screen, hardcase and buttons broken but battery and motherboard still working), replaced the inside components and made it work.

If there was short circuit on motherboard battery can be fully discharged but to charge it again You need to remove short circuit first. After that if nothing is burned by electrical circuit You can charge battery regular way.

Phone got wet, cleaned everything, battery has voltage, phone is a brick

The phone got immersed in water for 1 second. Like a dunce, I didn't turn it off and it worked fine and I didn't think about it. 36 hours later, on 50% charge and not charging (after working fine all day), it isn't detecting a cell signal, it's saying 0B mobile data used for the time period instead of the gigs it was previously tracking (and had a presumably accurate number in the gigs of wifi data). All the settings looked right, so I rebooted, it booted up, and maybe 30 seconds after finishing the reboot, it instantly and completely bricked. Power button did nothing for minutes, power+down did nothing. Plugging into computer does nothing, charging didn't seem to cause any warmth although I'm not betting my life on that.
I dissected the phone and there were small amounts of corrosion on the parallel pins near the audio jack, miniscule amounts in some other places, and "significant" localized corrosion at the microusb port and where the battery connector plugs into the motherboard. If the battery connector on the mobo is bottom right, corrosion got near, but didn't get on or appear to intrude into the EMI shield to the immediate left or to the one right above that, but I can't rule that out obviously. I cleaned visible corrosion off/out, checked battery and it was 3.8V at the mobo connector piece. I detached the mobo to check the underside, miniscule amounts of corrosion, cleaned, put back together, still a brick, EXCEPT charging clearly creates warmth in the inductive charger/battery area, but power and power/down still do nothing (no corrosion anywhere near those buttons).
If anybody has any bright ideas for things to try to salvage this guy, or places to check connectivity to troubleshoot further, I'm all ears.

You could try the old fashion method of pulling out residual moisture by placing it in a sealed sandwich bag with a cup of dry rice for a couple days. Sorry this happened to you.

What about the connectors for the cable from the switch assembly? Just disassembling and reassembling has caused issues for at least a few people reported on this forum.
Also, there is a board as part of the battery assembly. Just because there is voltage from the battery, doesn't mean there is sufficient current.
On a really old battery, you can have trouble getting a basic charge (been there, done that). This problem resulted in an apparently bricked device. The solution for that problem was to use a low power charger overnight. Something like the USB port on a computer. Then unplug and replug. If the screen shows the bootloader basic charging animation (white vertical battery), the battery itself is shot. But you should be able to get it charged enough to boot using a fast charger at this point.

I only unattached that ribbon from the mobo, not at the taped-over connection, and I'm like 99% sure it's back in the mobo fine because I've reseated it a few times and it feels tight. I never touched the junction between the power button ribbon and the mobo connector ribbon so that shouldn't be it. Pressing the power button definitely feels like it's depressing what it's supposed to. But I'm not even getting to the dead battery screen so wtf knows.
The battery (would normally) have more than enough charge to boot right now. Battery life was in the hours for constant use and it's been charged enough. My battery didn't seem to match the one in the teardown. It has

written on the wrapping and it wasn't immedately obvious how to get it and the inductive charger disassembled and off the midframe (maybe it was just good adhesive since I saw nothing obvious holding it to the midframe), but I didn't see any corrosion issues externally.
