Hi
My sister's G2 got wet and the lcd screen stopped working. The capacitive buttons, digitizer, and physical keyboard work fine.
However, someone took the phone apart before I came home and tried to diagnose the problem. I believe they may have damaged one of the connectors on the motherboard by bending (and perhaps breaking) some pins. I have attached a picture.
Should I go ahead and replace the lcd or is this damage just too much? The phone works save for the screen.

Sorry, here's the pic:

From physical appearance, it looks like the micro-sd card connector is spoilt, according to here. (Coincidentally, the touch panel ribbon is next to the Micro-SD connector)
After water damage, and probably some other motherboard faults resulting from opening the phone up without professional help, many things could've been probably either short circuited or damaged, besides the faulty connector. I'm not sure whether the phone will still boot up properly after these problems, let alone the screen not functioning.
I don't know about you, but if that happened to me, i think its best to get help from a professional or your service center.

Thanks for the advice and the reply. I'll consider seeking some techs in the area.
However, the phone boots up and the backlight turn behind the capactive buttons as well as the physical keyboard. The digitizer works because I can swipe across the screen (even though I can't see) and feel the vibration of unlocking the home screen. Also, the volume rocker works as well as the audio.
So, I may have gotten lucky. But it appears the microsd connector is damaged (not by water - by a person). I wonder if the top pins are just tension pins?
Hi everybody!
I wonder if there anyone have a spare parts for DesireZ (G2)? I need the mainboard itself for the repair. Thank you in advance for your help.

Hi all.
I cracked my digitizer... so went online and bought another one. Now before i make a mess of this and ruin the phone, i have got the whole LCD unit off the phone, but the contacts from the new digitizer seam a little different from the one on there... I have taken a pic of the current LCD with the part numbers so you can see what i currently have, and the one i bought is this link
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=260013588897
Now also, how do i get the digitizer off the LCD, and get the contacts out from under all that orange stuff?? do you just peel the orange stuff back?
Heres some pics that may help.. Any help would be greatly appreciated

You've got the wrong digitiser. Your screen looks toppolly with the wide ribbon connector and the new touchscreen looks like it is made for sony with a narrow ribbon connector. You can slice the ribbon to open the tracks to make it fit but it is very fiddly.
It also looks like you don't have a frame around the new digitiser which means removing the old one and sticking the new one to it before soldering.

Hi Richard
Thanks for that. I have got back in touch with the guy in HK, and he has the other one, so im gonna swap it.
In regards to the frame, is this the metal frame around the outside? Do you have to solder the contacts on the ribbon to the LCD?
Im not quite sure how to attach the new digitizer
I have done a digitizer replacement. The soldering work can be tricky. What I did was cut the orange ribbon on the new digitizer short by about 1cm, then extend the traces with 22ga magnet wire (from radio shack in USA) and then solder the extentions to the contacts on the main ribbon. Covered with electrical tape then restuck the metal shield on top of that. Works fine several months now. Be very careful when unsoldering the old digitizer from the contacts, rip one of those out and you will have big problems. Sorry no pics but it was delicate work and I dont feel like tearing the IIS apart and risking a malfunction.
has anyone attempted to disassemble the arc yet, i friend just bought his (after breaking infuse screen) and broke this 1 too...the touch screen on top if fine the lcd panel itself is torn/cracked was wondering if any1 has tried to take it apart yet..google didnt help.
btw had to order a replacement screen from hong kong..not available in u.s yet
cant be done. Must buy the lcd + digitizer together. I tried separating the digitizer from screen and ended breaking the lcd. It just showed up black and nothing else.

srry i meant hows the process for dissambling the phone..i ordered the screen+digitizer from hong kong..i replced the screen/digitizer on the infuse 4g and tht also came with the led/digitizer pre-assembled...but i was wondering if theres a guide on how to take the phone apart...it cost my boy almost 800 and dnt wanna be responsible for fukkin it up
Sent from my s#ift (drunk) using XDA App
I've done it myself after I lost my Arc on the pavement. It's not that hard really. It took me an hour or so to complete the exchange. The hardest part is splitting the screen and backframe (or what it's called) from each other. There are lots of clipses holding this beast together.
But it can be done
Lol an hour sounds time consuming...on a side note tho the design of it seems flawed. my friend sat on it with the phone in the back pocket. i do this with all my phones and never had a screen issues...i think the curved back may have bent the screen more than my friends fat a$$
sent as pixels travelling on an invisble superhighway!! via XDA App on the s#ift
UPDATE: finally got the screen from hong kong for 66$, it was easy to take apart, actually 1 of the easiest ive taken apart so far. the motherboard chip set separates easily from the front housing holding the lcd and digitizer, theres also a guide available on how to disassemble it on xda. thinking about getting my own arc now...hmmm

Hi, my arc s fell from motor cycle yesterday, the screen smashed pretty bad on bottompart. It still boot normally, what part do you guys think nee to be replaced? Thanks before.
hi there,
I had spilled water on the top of my galaxy nexus this morning and it wiped out the ear speaker. so i decided to open it up and eventually after some tinkering around I managed to fix it, however, I hadn't realised when lifting the mainboard that the volume switch was soldered onto it, and ended up breaking the connection. you can see it from the picture below. how can I solder this back? its a very small connection. i cant seem to find any videos or guides on how to solder back connections like this.
any help would be grateful, thanks
everything else with the phone is working fine though, but i lost the ability to go to recovery or bootloader

Can't be done, you broke 2 of the connections from the ribbon itself.
You'll have to either buy a whole new ribbon, or a whole new board with the ribbon already soldered on.
The picture also seems to indicate the pad being lifted from the other board. If that is indeed the case (feel the area of the board for a depression), your repair just got a lot more expensive - you may need to replace the board too.
Below point may be moot given the damage in question, but the actual soldering is best done with a high power but temperature controlled soldering station like the Weller WES51. You also need lead free solder, fresh tip, very steady hand, and quite probably a third hand (a tool that looks like two posable alligator clips, to hold your work piece).

i assume you mean the pads where the connection was? its ok its just that the soldered bits are abit lifted. the board doesn't seem to have any damage.
I've contacted Samsung about this, i hope they get back to me in time. i can still use the phone though, just cant change volume or get any vibrations lol

I never said the board need replacement because it isn't working , just that if the copper pad itself was lifted (or worse, torn) from the board, you will never be able to fully fix the connection yourself because you have nothing on the board to complete the circuit with, without going for more drastic measures.
Samsung may very well ask you to send the phone in, then I'm willing to bet that they'll swap the board as well. That is if they don't try to void your warranty.
yeah, so i ended up buying a faulty GN with a broken screen off eBay ill swap my screen with that one and sell mine too as faulty..
sad times, but ill be back
Hello guys. I'm currently trying to fix a friends HOX that fell and now the screen doesn't always display image although we can see it always lighting up (it turns on but stays black) .
If I press hardly the HOX's area in red while turning it ON, it works fine. I'm assuming this could be some broken welding points but would like your opinion.

I'm thinking of heating the area with a heat gun, but I'm afraid I'll kill the rest of the phone... what do you think?
Also, after disassembling the phone, the vibration stopped working and I've checked every flat cable and every connector I could find...no ideas to fix this one since it was working before I cracked the phone open.
Any comments are greatly appreciated.
Tks

Possibly a chip has become partly detached from the solder ball grid array due to the shock of the fall. You will not be able to repair this by heating, even if you could reach the melting point of the solder.
The manufacturer would repair by replacing the circuit board and the existing one would be considered unserviceable.

So in resume, my friend has a HOX for spare parts... damn...
Couldn't you pack the inside of the housing at the point where you need to apply pressure? Using a piece of card or something. Hardly ideal but would make it functional again
That has been my first attempt, and it's better but still, not enough.
I'm going to disassemble it for the tenth time in a final effort...
tks for the tip though!
So, I've just realized the back metal plate comes out nicely and I think I've found the problem for the GPU issue... that small component on the red area has a broken piece lol (WTF!)
I have applied pressure directly on top of it and I think it will be usable like this, but it now needs a bit of daily use to check if I'm right or wrong.
Can anyone identify what component type is that?
Also, unfortunately (and I don't have a clue how this has happened), the vibration stopped working after opening the phone on the first time, any one has any ideas of what to look for? I don't see any flex cable cut or any other damaged parts...
Tks guys.
Problem solved, some back pressure on the broken piece and the hox is good to go.
The only thing still not working is the vibration...

I have a black SPH-D710 on Sprint. I cracked the screen, so I bought a white replacement (glass, LCD, and digitizer) on eBay.
I took the phone apart and swapped the screens and reconnected the boards and it powers up great... except that I have no service. If I connect back to the cracked screen, it powers up great and I get great service. I was hoping for a quick and dirty swap, but it seems like there must be some code in the screen-side circuit board that is foiling my attempt. I found this video [goo.gl/YNLZE -- xda won't let me post links, yet] where the guy seems to suggest that my problem is the IMEI, but I don't have the first clue about trying to find that in the old part and moving it to the new one, if that's even the problem. I've combed the forums and don't see that anyone else has had this issue.
Ideas?
Did your original LCD get damaged? If not try just swapping the digitizer and using the original LCD. May require use of a hairdryer to separate the adhesive

That's how I had to do mine..One day I was drink a little to much, climbed a tree and fell out, my screen was shattered. Hairdryer is the key, the lcd i got from ebay, was brand new but..I now have the ghost menu issue ever since I swapped digitizers (don't understand how or why). Also check the connections, I know it's basic, but hey you never know

LCD is fine, just the glass is broken
The glass is cracked in one corner. The LCD itself is fine. The digitizer is fine. Basically the only thing I NEED to replace is the glass. The thing is, I have a replacement LCD with the glass attached, it's just that I lose service when I connect it. I'm just wondering if someone knows why, and if there's a workaround so that I don't have to screw around with trying to heat the glass off, break it even worse, and then be SOL.
Right now my phone works and the broken part is really only over the search button on the screen (which I never use anyway), but I was just hoping to restore it to 100% since I already bought the parts.
