(Q) Does this mean my WIFI is dead?

Hello Everybody,
Lately i had some issues with my DHD wifi
my device is rooted and i keep changing rom's from while to while
around 10 days ago i had used a rom and i noticed that when i try to enable my wifi it says Turning on and keeps like that
no networks showing, nothing happens at all just this stupid message and i had to restart the phone once or may be more to make the wifi works
i thought its may be something with the rom so i just changed it
i tried several roms but it still the same issue and since yesterday i could not made the wifi back on
whatever roms i change whatever restarts whatever removing the battery it still refuses to turn the wifi on
it just keep displaying the silly word Turning on all the time now
Does that mean i had lost my wifi connection forever, is it something with hardware now?
Please advise and help
Thanks in advance

Is the battery cover on properly? It's the pins that serves as an wifi antenna.

yeah the cover is closed properly, any other suggestions?

I don't have a dhd but ibsae this thread in the main section of the app. Probably just a educated guess but ik the wifi modules might have something to do with it

The cover is properly closed, you mentioned.
The little contacts are making contact? (pull a little on them to make sure they will)
Also cleaned the contacts?

yes, there is contactspray in the market, for removing the corrosion which blocks a properly contact. Dont scratch with screwdriver or something to "remove" corrosion. The thickness on the cover is very little.
I did it with the gps contacts and after doing that i had a less then 5 seconds fix. Before none....

[Q] Wi-fi issue turned screen issue...

Hi guys
Need a bit of emergency help (or maybe a hug).
I had major wi-fi issues and believed it to be the usual antenna problem described everywhere. In my wisdom, I thought the procedure to sort out the connector under the back-cover looked easy.
It was! I opened her up, "re-sprung" the connector - all good. However! My screen will now not switch on. There are no obvious issues internally or externally - I think I know which connection on the motherboard is for the screen but still nothing.
The phone is definitely on as I am getting notifications. Can anyone suggest a possible issue I have overlooked? Maybe a hidden connector somewhere? Or is it off to the mobile phone shop for me.....?!
Thanks
James

Probably not what you want to hear, but was it actually really simple to fix the antenna?!

Haha - yes. It's quite obvious when you open it up what the issue is. The connector is a small "spring" that makes contact with some copper plate on the backplate. This spring obviously gets depressed too far and won't spring back to make the desired contact. In theory, easy to fix. In theory...

Volume Power Button Cable Replacement Q

So I noticed my tablet wasn't really turning on when I pushed the power button. I took it apart, cleaned the contact points following a post I found on here, then the small metal connector flew off due to me loosing grip of the "tape" holding it on. I ordered a replacement part and I noticed there isn't a lot of info on how to change it, take it out, precautions to take or anything. My tablet is running the newest OS of android for the nexus 7, and is turned on. I would post a picture, but apparently I need to make 10 posts before I can do that...
My question (s) are:
1: Should I take out the battery to do this? I've seen a guy on youtube do that, and I don't know if that is a step I need to take.
2: How exactly does it come out? I've only seen one video of a guy taking it out and putting it back in. I couldn't see much due to the fact that where it connects is small. I want to make sure I don't break anything else.
and 3: I've heard people say that you need a "spludger" for this or something, I don't know what that is, but then again, I also heard someone else say you can use a toothpic to do the same thing. Is that safe?
Thanks for taking your time to read this, and I hope someone out there can help me out. I really just want to get the thing to turn back on with out me needing to plug it into the charger, or move the "power to the volume button" ect.

Any advice at all would be helpful.

I'm not sure what you worry about, it's an easy component to deal with.
Don't remove the battery, just disconnect its black plug.

I just never really tinkerd with something like this. I know it looks easy, but I never opened a zif seal or w/e its called. What exactly do I flip up?
I'm sorry for my "Noob" questions, I'm normally good with hardware stuff, but I want to just make sure I do this right.

No worries :good:
See the black flap?
Flip it up, slide out/in the connecting ribbon and flip it down to secure the connection.

PX30 Screen Issue white where black should be - HW or SW issue?

Picked up a used PX30 with a funny issue that I think might be HW related, but just want a second opinion before I do anything.
It is like it displays white where a shade of black should be, see attached picture, is this HW?
Model: ICE/HU/IN9053BL
Thanks for reading

Is it an MTCD/E device?

It is a MTCE_LM_V3.42_1

I would venture that it's software. The reason I say this is that the colors on the ruler for the reverse camera are correct. I believe there are display adjustments that you could try in the factory settings. perhaps. Or it could be as simple as maybe in the accessibility settings that it's set for high contrast.
Maybe a factory reset might be something to try first?? Also are the colors jacked up when the system reboots like for the Android splash screen?

The unit had been reset when I got it, but can not hurt by trying again.
The boot splash also has the issue on the animated logo, and it moves with the animation.
Before I do another reset, I will try to changing options in the factory settings, think it is the Display LCD type option i need to try changing, it is my first android head unit, but been android user for long time so will try flicking options and if all goes wrong a reset it is

It's wild that the ruler colors (red yellow and green) on the reversing screen were correct but nothing else is. Wow. If it's happening on the Android boot logo, that's kind of before Android has even loaded so maybe it's not necessarily software. I was kind of hoping maybe if logo was correct then something was getting flipped after boot up.
The color and display settings in the factory settings, I would think would be applicable regardless of whether Android has booted or not since those settings typically change settings in the MCU or main board.
Sorry for putting out more maybe's than answers. Hope you can get it sorted and report back what the solution is.

Mate, nothing to be sorry about, very grateful that your reading and trying to help
I 100% agree with that it might be some setting that can change the MCU or MB, but still have a naging feeling it is HW, so after work today, I wil take the unit out and take it apart and see if i can "see" anything, maybe a loos connection or something.
I did look in the factory setting and it does not have the color settings, its android 9.. So maybe custom rom and if problem still there then take apart.. Hummm..

I will share with you that the TFT board used by Dasaita is one of the many weak points of these head units. That's the board that has ribbon cables between the main board and the display. I suppose it's not impossible that one of those ribbon cables could not be seated properly.
I got Dasaita to send me a replacement TFT board for one of the units that I installed in my truck. It got the display going again but unlike your issue the backlight wouldn't light up. I found the actual component on the TFT board that was smoked. There is a zener diode that is used to control the backlight voltage. It overheated as a result of having the screen brightness at 100%. Interesting that they set the brightness to 100% from the factory, imagine that...
Those ribbon cables are very cumbersome to get seated into their sockets and they didn't leave but very very little slack to work with.
I just find it odd that the colors for the ruler on the reversing screen are correct. The color settings I was referring to before should be found under the "other" category across the top in the factory settings. You might need to scroll down that list of settings to find them. Also the factory settings are not necessarily tied to the Android version. Those are tied to the MCU firmware version. If indeed your unit does not have these settings, it could be one of the differences between your PX30 and my PX6. It's possible these might be made available on your system using an alternate password instead of 126 to get into the settings, but I have no idea what that password could be.

Hi Friend, were you able to solve your problem? I have the same problem with my PX-30 multimedia. I'm thinking about opening it and seeing if the cables are connected correctly. Did you need to change something? or can I change the factory settings in CAR?

Hi mate, I have not been able to fix it. The only thing I "did" was to unlock the factory settings and looked around in there, but was unable to see anything that might help. Also I did take the unit a bit apart to check for loose cables but did not find any. My next step is to install a custom rom "just to see" if it is a software issue or not.
How did your problem come about? Did it just happen one day?
6 month of use? is that from new or second hand? Or was it just in the car you bought?

Thank you for the clarifications.
I bought new on aliexpress in March/2021 it worked fine until 3 weeks ago, suddenly for 2 days it was alternating the color "Normal x negative screen"..
Right from the start I suspected some HW problem, since in my neighborhood, there are many holes and the car shakes a lot.
Right now I'm talking to the seller requesting permission to disassemble the multimedia and see if there's anything loose.
I have a hunch that it might be something in FLAT or BGA since the car is in the sun and several times when I got into the car I saw that the screen was super hot (even off)
As soon as I move forward, I'll share it here with everyone.
*I'm sorry for my English.

Thanks for the info and update mate, I hope you have luck with them giving you permission to open it and check.
I might do that with mine again as I did not take of the circuit boards, just took off cover and checked LCD cables.
Will also post updates if I do make a 2nd attempt and good luck with yours.
Your English is all all good mate, nothing to think about

If your unit is Dasaita, no need to ask them for permission. It is common practice for them to provide replacement parts for us customers to "fix" issues which most often requires opening the unit. The warranty on these units is for the most part worthless as it would cost more to ship the whole unit back to Dasaita than it's worth as they typically expect you to pay shipping cost both ways. Just saying.

The seller returned me and asked to do a firware update, I performed the procedure he instructed me to do, but it had no effect on the screen (I just noticed an improvement in the audio/equalization)
I'm waiting for the next steps, they asked some more day to evaluate with the manufacturer.

Hope that they can resolve the issue to your satisfaction. Please keep the community here updated.

Question Low audio volume when recording video and during messenger calls

Hi,
I experience very low volume after recording a video with the Xperia 10 III. The same thing happens when I make a messenger call/messenger video call. The other person barely can hear me.
Normal phone calls work fine (at least nobody was complaining about from the other end).
I am not sure, but I think this was the case since I bought the phone, but I did not care too much, because I did not use these functions often earlier. Last week I had a few video calls, and always had to go and find a headset (with the headset everything was fine), because they could not hear me. Very frustrating. Also the video recording ( I use the factory camera application).
Did anyone experience this problem? If so, did you find any solution? I feel it is software related.
Sw version: 62.0.A.9.11
Thank you in advance.

Next to the USB socket and on the opposite side are holes for microphones. Check to see if they are clogged. Maybe something has fallen inside.

Thanks for the answer.
This was the first think I checked. Under microscope I don't see any clogs.
But, do you have the same phone and no issues with the above?
Thanks

I don't have this one, but I had a model like this where the inside of the hole was stuck with flecks. On the outside you could not see anything, because there are bends in the hole. Pull out only with a thin copper wire!

Thanks, I will double check tomorrow at work under microscope and try to clean with a wire.
In the meantime I did some searching:
On another site in the reviews area more people mentioned this issue (the mentioned the facebook messenger call issue):
Sony Xperia 10 III - User opinions and reviews - page 4
www.gsmarena.com
It is possible we have the same hardware related issue, but it is kinda unlikely.
At this point the main question would be, does anybody have a xperia 10 III without this issues?
