[Q] Problem with the Audio Connector - LG Optimus 3D

Hi Guys.
I have a problem with my Audio Connector.
When i plug in the cable it instantly falls out again and if i hold it there is only music on my right speaker.
I thought about replacing it: I found something here: http://stellatech.com/lg-p920-optimus-3d-audio-connector-kopfhörer-anschluss,a,de,813541.html
Does someone know how to replace it safely or how the repair it without replacing it?
Would be nice if someone has an answer for me

Jack is not hardwired to the logic board. It's just a ribbon.
It's extremely easy if you don't lose the screws.
Remove the screws from the back and unplug the clips holding it in place. Then you need to remove the sim board , then the logic board...
The headphone jack is held in place by a double sided tape.
Remove the old one , plug in the new one and close up.

WAIT THAT'S NOT NECESSARY!!
I've had this problem too, it's because the Optimus 3D's Audio Jack isn't protected from dust !
Get a toothpick and carefully take the dust out like 3-8 times or so, you have to go DEEEPAAHHH (wtf)
and at the bottom, press the toothpick against the wall and drag the **** upwards! get it to the choppah!!

Well that's how you do it, I should probably leave the computer now lol

Damsel in Distress - USB Port is loose!

Hi all,
The mini USB port for charging and connecting to PC has come loose on my Tornado (i-mate SP5)... I don't really know how it happened (possible jolting in my pocket while running?) but now the thing can't charge or connect or anything. It seems the actual USB casing has come loose and the things inside can't make a connection to charge - err, I don't have the best technical jargon, please bear with me
Ever since I upgraded to 6.1 my Tornado has been my best friend. I'm loathe to buy a new phone (after all the blood, sweat and tears that went into upgrading) so I was wondering if anyone knows how to fix this problem... I could easily take it to a repair shop (I guess), only I'm in a foreign country that doesn't make HTC and the coffers are low... I've managed to take the thing apart to an extent (struggling with the last two screws under the battery compartment), but does anyone know whether taking it apart will actually allow access to the USB area so I can try to fix it?
Please help me if you can!
Thanks,
Jessica
Well there is always a knight in shining armor to help D I D
Any ways , i had the same problem too, while connected with cable my phone dropped and USB port became loose, if you have managed to open the casing and pull apart (clipped togather) both plastic front and back than you can see the board and the usb jack. Mine was completely soldered off . I opened the set completely and soldered it back. ( Added benifit i cleaned dust particles of LCD Screen) OR you can take it to any mobile repair shop where they will be happy to charge you and repair the mobile.

Here is a guide
It'll take a little wiggling around with a Credit Card or similar thin hard plastic to split apart the covers(See #6 on the tutorial, don't use a screwdriver or nothing metal), but be patient. It'll split. First time I opened mine, I was scared to death, now I do it just to kill bordness. Beware of a little connector between the motherboard and the keyboard plate(#7 on the tutorial). Just pry it off gently and when assembling back, make sure you push it back firmly into place. Feel free to message back if u need help.

You had a broken Mini-USB port and you solve the problem by Hard Restting your device? ummm Don't think so mate. A little soldering might help ;->
ok I do not read all post...
thanks very much
now all i need to get hold of is that T5 screwdriver... i hope i can fix the USB port without needing to solder it...
thanks again guys, i'll let you know if it works...

most likely you will need soldering. Take the phone with you to Sears. They have the screwdriver. But I believe it isn't a T5, I think its a T6. You can go to any electronics shop and have them do the soldering. Shouldn't cost you more than a $5.00 tip.
Thanks i never knew this guide existed i worked on unproven grounds scratched my phone a bit , thanks any knowledge is always welcome.
Soldering...
Um, don't solder this yourself without a heat sink. I melted the entire USB assembly when I tried earlier this year, so now that phone can only be charged by removing the battery to charge (which is ok for a backup phone) but I can never update the OS again (which is not).

You can still update the OS by copying the OS file to a miniSD card and change file name to TORNIMG.nbh and boot the phone holding camera button for bootloader and follow instructions.
well, finally got round to soldering, i hope it works...
gents, thanks for your help and i guess i'll be posting here in a few minutes when the damned thing still doesn't work
I used circuit board glue with partial success
I had the same problem with my Tornado. I tried soldering, but the soldering iron I used is old, and the tip was too big to be precise enough to get the job done properly. Or I just suck at soldering. Not sure, but anyways, I ended up using some fast-acting circuit board adhesive from Radio Shack. The phone will charge now, but will not connect to my PC via USB. For now, it's fine, as I already had upgraded to WM6.1, and haven't needed to do any further OS upgrades, and I don't really need to do any email or contact synchs via USB, but it's still kindof annoying. Also, my speaker seems a little static-y and muffled since the attempted soldering. I think I might've damaged a circuit that relates to the earpiece somehow. I guess the moral of my story is be careful when soldering if you don't really know what you're doing. Not that it isn't common sense already...

I don't think so. I have tried naming the file TORMING.nbf and TORMING.nbh on multiple Tornado devices, with multiple miniSD cards, with and without SIM cards, in various states of registry unlock, and superCID unlock. I can't make the phone's bootloader do anything unusual. If you want to give me specific steps I am happy to try again.
yes, kkrull is right. I also tried but not working. I think it is not that easy.

Want your opinion on this phone black screen issue (see picture)...

My wife's phone got water damaged a few days ago and I took it apart and removed as much water as possible and put it in a bowl of rice to set.
I finally tried turning it on today and it seems to work fine (I think, syncs etc.) except that the screen does not power on. I can see the backlights when I look at it from an angle so it appears to receive power of some kind.
I took it apart further to see if I could see anything and I found that on the display cable there is a black area which looks like it is damaged/burnt on the cable. There was also a little bit of black on the connector but I believe I got most of that cleaned off, but the area on the cable does not seem to be able to be cleaned.
I don't really know anything about electronics or parts of a phone and was wondering if anyone that did could suggest what my next steps would be to restore the phone/screen to operational condition? Part replacement etc.
Thank you.
It sounds like the chip connected to that cable got fried, hence the burnt spots.

If that's the case I'm assuming there isn't much I can do? I don't want to solder anything but could can replace anything that just snaps in.
Thanks.

[Q] Camera crashes after replacing digitiser, anyone had this?

Ok so I replaced my own digitiser to save £100 at the repair shop.
All went ok and the phone works fine now apart from the camera - which crashes every time I open it. Same result with any app, one app said it couldn't connect to the camera and then closed, so I guess I've done something to it.
All looks ok, no loose connections, but camera still fails. Any ideas?
Had this with my legend mine turned out to be a connection on the actual camera shorting out,Check all the pins around the camera pod for damage

Yeah checked and all seem ok, but the camera is still borked so it's gotta be something like that.
I'll open her up again for another check, just hope I can fix it. Mightily annoying having no camera.
Oh well
Also check to see that no wires get crimped or smashed down when you put everything back together. I replaced a friend's iPhone digitizer and had something pretty similar happen. The connection was there but stuff wasn't working right. Took it apart and saw wires were sort of smashed so was more careful the next time. No wires were damaged or anything and after doing it again everything worked perfectly and still does.

Good tip thanks, will try that tonight.
Hi all, can confirm the same problem, on the same phone, and the same sort of solution, thanks to your suggestions.
It came down to the black lock block on the ribbon connector being askew. Very fiddly to put back but now the camera works....Hmmm better check the front camera now.....

Screen Problem

Hi,
My phone has a problem, i hope someone can help me, it started about a month ago,
When i slide the keyboard the screen would freeze, the image would freeze or sometimes it would become like this:
http://www.esato.com/board/img.php?id=140762 ( this is not my phone its just a pic i found)
This problem would be solved it i gently slide the keyboard back in, the screen would be back to normal, sometimes i had to slide it out and it
alot of time to make it work.
Well, today i woke up, with the screen of my phone all messed up ( like in the picture), i slide it out and in alot of times but no luck.
I turned my phone off, when i turned it on, the screen doesnt lighted up or showed something, the phone just vibrates, i took off the battery and tried again but no luck.
I read somewhere that i could be the flex cable, so i ordered one, but its gonna take some time to arrive.
Anyone had this problem before that can help me?
I didn't encounter such problems on MT4GS yet. But being a slider phone enthusiast I could 100% say it's a flex cable thing since I encountered that problem more than a dozen times already on other phones(nokia).

I would strongly recommend that you get a cable with the speaker already soldered in place....
+1 to that, get as much pre assembled as possible, this is about the most pain in the butt phone I've ever had the pleasure to disassemble. Read the last few posts here!

thanks for this bit of advice.
Disassembling the front of the phone is a pain. I'm a fan of spending $40 on ebay on a broken phone (where the screen still works just fine) and swapping out the fronts. That will get you a new flex cable as well. Otherwise, you risk having to get a new flex cable *and* a new LCD.
Agreed. First time disassembling front I was scared not to OVERheat phone internals. I ripped in half trackpad ribbon, damaged lcd back cover and got a lot of problems from it.
Then I bought broken phone with good front, but dead LCD. Second time I just lost it, I heated phone so hard that I got burns on my fingers, but it was worth it, LCD glue came off soo nice.
So better to overheat, then underheat when disassembling front LCD.

[Q] Help my power button is sticking or broken

My power button is sticking or broken. When ever I use it to close the screen It stays stuck and asks me to reboot or just flashed. Is there any way to fix this? Can I order an new button and put it in?
Thanks for any help!

Yes a permanent fix would be buying a button from Ebay for a few bucks and replace it.

Did you check the continuity with the new button? You bought the button that required to solder to the main board right? not just the power button cover!

I assumed that you soldered the button correctly, I would use an ohm meter to test the continuity when the button is pressed and released, just to verify that the button is good and make sure all solder joints are good. If all the above checked out, then the last thing is replace the main board, shop on Ebay for a clean ESN board (price range from 80-90$. I don't know if you want to go all the way or just use xposed app to by pass the button and wait to buy a new one?

Usually, after soldering, you need to verify continuity, sometime you may experiencing cold solder joints, where the lead is there but no contact. The board is coated, so you need to sand down the contact so that when you applied the lead, it will make contact.

I'm going to try again tomorrow. I just don't know how I can get the two little prongs under that button soldered into the little holes on the motherboard. Any suggestions? Would liquid solder work?

So I think i messed something up resoldering it. Now it wont turn on at all. I talked to verizon and they are sending me a new one (for free). What is the best way for me to reformat my phone if it wont turn on.
And
Should i leave the button unsoldered inside the phone. or attempt to resolder it back on so its just there?
I dont want to be charged for tampering with the inside of the phone.
Thanks
Resolder the button back on and send back the dead phone. I'm not worry about the software but messing around with hardware is more concerns.
