i tried, they wont cover accidental damage. And my warrantys been voided since someone opened it up..

I bought a second hand phone and it did turn on however there were a numbers of problems with my phone, it had a power button that didnt work, unresponsive parts on the lcd and a quiet in call speaker.
Your best bet before trying to replace the whole pcb is opening your phone using a teardown guide

Make sure you read it a couple of times and go through the pics so you know what your dealing with, find the power button, make sure its intact and adjust the ribbon cables.
Otherwise just find a cell phone repairer on a classified ad like criagslist or kijiji.

i had someone take apart the phone and they said everything inside looked good. Im going to take it to another place tommorow and see if they can fix it....otherwise this is the 2nd smartphone that died on me. HTC told me to go to Bell...and i bought this phone 2nd hand. Trying to send my Galaxy S in was a Pain....anyone here know of good 3rd party repair services in Ontario?

I hate to say it, but it was second hand for a reason. Ever try switching the battery? How about changing the power supply?

Yes. Start simple. First check your electron hose to make sure you are getting power to the device. Also check the battery as well as the prongs that connect with the battery tabs. If things are good there, then think about tearing into the phone.

no no, dont say that. This phone was fine for 3 months, i dropped it at a club i went to and water got inside the phone....i took it to 3 repair people and they all said the Main PCB motherboard is damanged (water) soo does anyone have any idea where i can find a motherboard?? i have no problem with costs of replacing it. As long as its not more than the phone itself.

You didn't mention water damage in the OP. You said something was loose. Water damage is completly different.
Try ebay.

Hey i found these 3 ads on ebay...do you guys think that a swap of the motherboards would be fine? heres the ads. I contacted the seller and they said the battery was used and thats it but phone seemes operational....i know its a risk, but is it worth it guys?
..need help on this one.

why swap the motherboards if the new phone is working fine. Just transfer data and you're done surely?

Reason being the other phones have minor problems, like speaker doesnt work, or some of those phones wont pick up signals and i think thats due to a bad radio flash or if i just flash a radio everything should be working fine.

can someone please clarify this? if i buy a phone with a speaker problem and transfer the main PCB board to my old phone...will there still be a speaker problem? or is the speaker a separate unit itself and not related to the pcb board?

one of the phones i am bidding for says it might not be able to guarantee a connection to mobile network (send sms,make calls) could that be a radio flash problem? would i be able to fix that??
another is one of the phones boots on and shuts off, i take it that could be a bad flash or something? its only about $20. just trying to weigh my options cause the new phones are lkike bidding for $350 lol im not that rich yet

I found out that my MOTHERBOARD is fine. There was water damage but not enough to go inside to the main board! My dad tested the battery voltage and found i wasnt getting any voltage.
i went to future shop and found a lady to let me use her battery and sure enough the battery was working and phone powered on!!! so i guess my battery was shot from dropping and popping out of phone while recording a video.

ordered these from ebay....are they any good? they look decent

Those look like the batteries I got. They were about 1/2 of the claimed mah rating. Worst case, they wiill get you running, and that charger is pretty good.

Galaxy Nexus dropped into water! Australians in melbourne look here!

Hi guys ! I hope Im posting this on the right section, anyway posting this on behalf of my friend,
He dropped his Nexus ( still under warranty) into a toilet handbasin which has water in it . He turned it off and took out the battery and cover to let the phone to dry overnight. His speakers weren't working at first , but after a few days, they were fine.
The problem is :
i)Charging is inconsistent now. Phone doesn't charge even it is plugged in , sometimes it does. He have to keep on trying till it says charging AC)
ii)Phone hangs A LOT
iii)Reboot more than usual
iv) Shorter battery life
Question :
i) He wants to return it to Vodafone Australia but not sure if they know the phone had drop into water? Is there a way to know?
ii) Is there a way to fix any of the problem?
iii)(For australians in melbourne) If he can't return it to vodafone, any good service center to recommend?
Thanks guys

ii. Try soak in rice overnight. Should be done after the drop. Anyway u can always try. It works on my Nokia .Dont know if it work on smartphone.

Hey thanks ! kind of been a week already . Think it still may work?

Chances are permanent damage have been done.
Put it in silica gel next time, i think it absorb water better, but remember to bake it first before using it.

Think he can return the phone without getting caught? I heard there's a red tape some sort of water indicator inside the phone. Is that true?

Yes there is. If you take the battery out, at the top of the 'slot' that the battery rests in theres a little white piece of "tape", that normally has just X's on it. Not sure what it changes to if it gets wet, but thats how they would tell.

Thanks will check on it

I believe they have it inside the phone as well. I don't have any water indicator stickers on my battery.

Hi guys! I have a similar problem with the galaxy nexus. It dropped in water, now works pretty fine, but from time to time there is a chaging message on the screen even when it doesn't plugged to the charger. And it draining the battery much faster then before. Is there some ways to fix this problem before I took it to a service center?

Guess we are all on the same boat =/ , check your indicators for now

Unfortunately there's no any indicators inside the phone. Any thoughts?

There is one actually! http://guide-images.ifixit.net/igi/qqCnaRuXSHnMhDXJ.huge
Notice the square XXXX inside the phone. Its on the right frame just above the place where the battery is.
My friend checked his, the indicator still okay! sent back to vodafone!

Correct me if I'm wrong, but 99% of the time that indicator is white and BECOMES red when there's water damage. As in, red Xs means water damage.
Edit: After thinking about it and using a bit of common sense, yeah no - red Xs has to mean water damage. I also checked my own phone (with no damage) and, as expected, white indicators. I have the Sprint version so maybe some small, tiny chance it's changed, but neither of mine are X'd and I bought it brand new.
Editagain: Did some research. Apparently my indicators are reverse to everyone else's, but they could still deduce that the problem is water damage - it's not too hard to determine for someone with a bit of hardware experience. I wouldn't get too excited.

[Q] Touch Screen Gone Crazy...

Hi there,
I've been using WFS for over three months and one night I placed it in front of air cooler and slept..
From the next day onwards my touch gone wild.. Only 1/4 of the vertical part in the left of screen reacts to touch and the remaining part is dead.
when the device gets heated due to usage or by placing in sun magically touch worked normally as nothing happened..
I brought this to the notice of technician in service center. He checked the device and stated everything with digitizer is fine..
Could anybody explain me whats happening and provide me a solution...
thanks

Maybe a bit moisture accumulated on your digitizer......try using a hair dryer at medium or low heat

Keep the phone in a rice container for 24 hours. remove battery, memory card and sim.
Lock the container.

Sure about this???

Yeah it does work. Google it out.
Rice container can soak the moisture inside the phone (if any). I once lost my phone to water (Not this one, my old nokia phone) and on some googling I found out this.

I did like what you said but nothing happened. Its acting like it is having some kind of switch. As soon as the temperature fell below some level 3/4 of the left vertical part of the touch screen stops working... I don't understand the reason. Technician said there's nothing wrong with my digitizer. Any more help...

Why not just give it in to the service center? Show them your problem. Anyways its in warranty. And I'm hoping you haven't rooted or anything.

That'd work if there was some moisture in the phone. It'd drain out moisture but your problem may be caused coz of something else. Better give it to service center.

A bit of a problem...

Basically, someone gave me a very not so clever idea of microwaving my phone to charge it. Being the bright spark I am, I tried it and it worked! 10 secs = +20%. However it overheated my phone really badly, and now the touchscreen doesn't work on the top half of the screen, the home button doesn't work, there are some wifi problems, like very weak connection (where before it was very strong) and the backlight for the back button is very dim.
Now does anyone know of any fixes, or if HTC might repair it on warranty, (but I rooted the phone so I dunno )
All help is greatly appreciated

This is a joke, right?

It actually helps to recharge the battery, as it gives the electons in the battery more energy, then charging it from the wall or PC can give, and also allows the flow of electrons to be more smoother, causing less resistance and less overheating. What I didn't realise is that I need to put in just the battery not the whole phone (metal in the phone duh) and yeah, I'm stuffed.

It is a myth that originated from an APPARENT claim made by Apple saying not to do it, which has since become anecdotal evidence that you can and should.
It's nonsense.
Microwaves cause particles to vibrate but do not deliver electrical charge. Added to that the fact your battery contains a variable moisture content that is vaporized inside the sealed container causing either structural damage or full rupture. Plus the heat can and does destroy the protection circuitry built into the battery to prevent under/overcharge.
There is SOME research into using microwaves to produce lithium iron phosphate batteries, but doing it to a lithium cobalt oxide battery is EXTREMELY dangerous and will shorten it's life if not permanently damage it structurally.
It's another example of the power of Facebook to instantly convey the most ridiculous things to millions of people.

It would be totally irreparable in any case. It would have to be a totally replaced phone. You've completely annihilated all metallic components, which is basically all of them.
Even if you had only put the battery in the microwave in any case, you'd have exploded it and destroyed both battery and microwave, or you'd be walking around with a bomb in your pocket.

Phone turns on for few seconds and shuts down

Hi there,
I have a problem with my G3.
2 days ago my phone freezes for few seconds, then turns off. I had to reinsert the battery to turn it on, it works for about 20 seconds after restart, then freezes and turns off again. I bought new battery, 'cause I thought that's it but no.
After disassembling I saw one black square and on google images it's grey like other ones.
I've tried a lot of ROMs, updated TWRP and still nothing, so I think, the black square is the problem.
Is it fixible?? Will I have to change my motherboard??

I found out it's the SMD 0805 4.7uF 16V capacitor. Is it possible to replace it (using heat gun, tweezer soldering iron) with new one??

I was trained in replacing them. But i have found that most people do not have the skillz needed to replace various micro circuts but i u do go for it at this point nothing to really lose if i had a good diagram with parts list i would shoot for it. It may take a micro iron a heatgun may damage other components unless u protect most of the surounding area with some heat resistant insulation. This day in age most people are lazy myself included i just prefer to replace the board. But if i couldnt get one i most def go for it

Also if the phone dont turn on make sure ure 1 year waranty is expired cause lg will replace it if it dont boot to os or fastboot or dl mode they dont know its rooted basicly waranty still in play
