The charge port on my phone went bad and needed to be replaced. The replacement went smoothly but now it I have no bluetooth or wifi antenna. I get maybe 1 bar indicated if I am a few feet from a wifi hub and bluetooth isn't working at all. I thought it might be something to do with the new charge board so I replaced it again with the same results. If anything it might be even worse now. Any tips on what I should be looking for that is wrong?
Sounds like you broke one thing fixing another . If it's physical damage you need to go backwards and check all your steps and see what happened.
If software issue try reflashing modem.

I found the problem and it, which is a simple one, The fix though I think is going to be difficult. A very, very small capacitor is missing from the board. I must have hit it during the charge board change. If I knew the value of the cap I could probably solder a new one on. I have no idea how to find that out though. Here is a picture of the missing part.

A lot of internet digging has turned up the spec on the missing cap-
Samsung part #2203-006665
0.0022NF,0.25PF,25V,C0G,0603, C-CER,CHIP
That particular number is out of stock everywhere but I was able to find an equivalent from DigiKey.com
Samsung #CL03C2R2BA3GNNC
Digi-Key #1276-1403-1-ND
I bought 10pcs @ 2 cents a piece.
Good luck with the soldering,
In case that doesn't work for you maybe this will work for you.
Pp. Lol
Soldered in the microscopic capacitor yesterday and phone is back to 100%!

after dropping incredible 1, loose piece, help me find where it belongs!
you see the two pieces that were loose after my Incredible took a hard drop. It has taken many. I want to figure out where these pieces go, and if maybe something else is missing.
My upgrade date is soon, so please, no recommendations for getting a new whatever. I love my Incredible, its amazing it has survived so much wear and tear!
Whatever these are, they may be antenna related, as that is the function that doesnt...function. WiFi works, GPS, etc. just no cellular data connection. Any help is greatly appreciated. I've found a good youtube vid - Droid Incredible Disassembly by TechRestore and paused frames of it and looked back and forth, and just cant catch where these parts came from!
Many thanks in advance!

That looks like part of the USB jack. Don't know if you need it or not, but the USB plug may not fit tightly if it is not there.

Where did it drop? The guy above might be right, your metal is showing on the USB port. As for signal.. I haven't a clue, I suppose it could have been a hard enough knock to disconnect the signal?
Is the yellow plastic a scrap paper that came off the wires shown in the video, which by the way the video was actually pretty awesome.

So I successfully replaced the lcd on my optimus G...unfortunately I unknowingly broke the battery connector during the process (the female part soldered to the board).
Took me a while to realize what was going on, the phone was heating up and turning off randomly.
Anyway, it looks like the rightmost solder pad has lifted away from the board and the battery connector. Be REALLY careful when removing this thing people!
By chance does anyone here know where I might be able to jump this connection to? This solder pad seems to go nowhere - or at least not that I can see.
Thanks

hey u ever fix this issue? I have the same problem right now. Fixed the screen broke the battery connector lol.
I did not. Gave up and ended up getting a new board and giving it back to the owner. Wish I would have tested the new one before I gave it back. Perhaps there is a jumper we could have used.
Did you break the same pad?

Hey all; I got a Nexus 7 this past December and everything was working great until yesterday.
I took it out of my school bag and when I pressed the wake button this happened:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",

"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Now whenever I wake up my Nexus the same thing happens. Sometimes it goes back to normal after a few seconds, but it continually freezes or has random slow downs.
I reset the device and erased all my data and whatnot, but still the same has happened.
Any suggestions?
What ROM are you running, stock or custom? Try reflashing a ROM (let us know if you aren't familiar with that) in case something's corrupted. Hopefully it isn't something with hardware.
This should be a hardware failure.Take it to the service.
@Pandae: Everything was stock. @GeoVali99: Correct-o, sir!
Ended up being a hardware issue so I'm getting it repaired.
I appreciate the words though!
Hi!
I've got the same problem.
Can someone tell me how to fix that Problem by my self?
I have no guaranty left...
Thanks!

Not a big deal. The LCD is fine. What happened in my case when I got exactly the same screen is that the amber ribbon (LCD to motherboard) seated wrong, and I bent a pin on the motherboard connector out of shape. You open the back cover and reseat it, but make sure you do not damage the pins. In other words do it very gently, do not force anything, and monitor it all with the help of a magnifying glass.
I had a problem with my head unit and wound up purchasing a new one. Between order and delivery dates, my original unit started working again and would like to sell it. Is there a way to purge it of all personal data without performing a complete reset?
On a side note; who wants a nine-month-old head unit?
Can you put some photos and a complete description of your HU (MCU version, etc.), please?
I have the dual-core 800x480 version of this;

Mine is a Joying unit.
It has worked fine for the past several months, but developed an issue where the screen would flash, pixels would be in the wrong spots, and then go dark. Despite all that, the touch screen part of it worked fine (as long as I knew where to press, I could get it to work). After much discussion with Pumpkin, I removed and installed the ribbons to the screen. This did not fix the problem right away, but the unit is working fine now thanks to the FM Principle. My skills have reached their very limited limit and I fear the problem will manifest again.
I personally think there is an issue with a connector to a ribbon or else the screen itself has problems and that someone with a little bit of knowledge can make this 100% again. If I hadn't jumped on a holiday sale, I would keep it and be happy. But I did jump on that sale and would rather recoup some of my money than install the old unit in another vehicle or give it to my cousin to enhance his electronics education.

Hmm. Wish I saw that before I did a full reboot.
Thank you. I will keep it in mind for next time.
Hi all, yesterday I replaced the digitizer on my son's s4 mini, first time I've attempted this, but seemed a fairly straightforward process, took the phone apart without issue, placed all the relevant parts into the new digitizer and reconnected everything, put the battery in and powered up the phone, and the screen seems corrupted, I've taken a picture to show the issue.
Any help that anyone can give will be greatly appreciated.

I wonder if a flex cable got partially torn in the process? I have never done such fine work, especially not to an S4 Mini, so I'm not aware of all the pitfalls.
Best of luck though!
Nothing that I could see, I've checked all connections and cables 3 times, and they all seem fine, I have sent the ebay seller that I brought it from as I fear the screen is faulty, but as yet no reply, thanks for your message ?
