[Q] Mainboard diagram? Not charging - Captivate Q&A, Help & Troubleshooting

I have an sgh-i897 that will not charge. I've look all over the internet and I can't find anyone who has fixed the issue. The usb port doesn't look physically broken under magnifying glass. I was wondering if there is a charging 'fuse' on the main board? I can't find any images for this, I know some phones have these and they can be soldered to make the phone charge again.

I recommend ya contact mobiletechvideos.com
They would be able to answer ur question.

What rom are u running.. secondly what TV do u have?
Sent from my LG-P990 using xda app-developers app
Never mind i didn't push the cable in far enough to the phone.
Congrats on figuring out what the problem was. Hopefully any future problems will be as simple as this one heh.
Glad u got it sorted.. I had a look to see if their were any TVs not compatible.. turns out there isn't lol.. its a universal standard just like scart or dnla so u should always check both ports for dust etc.. now we know thanks to you

Ohhhhh...wow!!! ...
Thanks. I should have a new sync cable design done this weekend as long as it rains all weekend.
Just need to figure out a new way to attach the cable to the watch
Cool to see.
Sent from my SM-N900W8 using xda app-developers app
hmm.... wireless charging mod seems doable... wonder if anyone has tried, i might this week.
Looking at the components you'd think they could have designed a smaller cradle. Not a lot of stuff going on in there.

Dust under scree

Hello everybody,
A few months ago I noticed a few specks of dust under my screen. Today I noticed that it was much more than it was before.
I saw on youtube there was a way to disassembly this phone (with unscrew screws and stuff) but I thought that is way to risky with putting it back.
Now I'm wondering, is there a easy way remove the screen (without rescrewing)
Sent from my LG-P880 using xda app-developers app
Same here. 3 points of dust. I repair phones at my work, but our lg is really tricky. I can live with the dust.
Sent from my LG-P880 using xda app-developers app
Me too
Gesendet von meinem A210 mit Tapatalk
How do you expect to take the phone and screen apart without unscrewing it? If you are semi-competent it is an easy enough task - I did it with no problems at all.
I thought there might be a way to do it by heat the screen with a hairdryer or something
Sent from my LG-P880 using xda app-developers app
You should take it to some repair service it will be not that much expensive since its not a repair its cleaning and they will take your screen off them will use new glue which probably will prevent dust going under the screen. Here in my country the procedure will cost arround 10-20 Euro.
That's a good idea

I suspect you're dutch like me, so would you be so kind to let me (or us) know what they charge you?
Sent from my Nexus 7 using xda app-developers app
Indeed, I'm Dutch. I'm just 16 years old so I don't have much income. Currently I'm saving for a new television.
I think that when I bought my television, I'll let "them" clean my screen and tell what they charged me.

Student here, so not much to spend either.. I do take apart phones from time to time, but as maus01 said, our 4x is kinda tricky..
