Hi, a friend dropped a glass of beer on his galaxy i9100. Phone looks dead but when he give it to me i've tried another battery and the phone turns on with apparently no problem. So he bought another new original battery, put on and charge the phone. But, temperatures reach critical level and the phone stopped the charge. The temperature raise even without charge with battery in and phone on. So i disassembled and scan for damaged components or some trace of "beer" but the phone looks clear. I then sprayed with a product similar to wd40 (we call it crc in Italy, removes dirt and clear electric contacts) and wait for dry. But same problem. I turned on the phone partially disassembled and the heat is concentrated in the flex hook of the frontal buttons but probably the heat comes from the chip near that.
unfortunately there is no code on that chip so i hope you can understand wich i'm talking about. The only thing is that i don't really know if the heat is from that chip or the flex hook, i don't know how to test it. Looking at it there is no sign of damage. Any advice?
Hope you can understand the problem and apogologize for bad english
ps: with the crc the temperature focused on that chip, before that all the charging flex was over heating
Just post a picture.
Are you talking about the usb/mic board.

this is the place where heat reach is max
no ideas? i cleaned the phone completely and nothing changed
All I can say is you look through previous posts about motherboards and see if anyone has an old board you could get.
I dont know how easy it would be to change that component your after.
I dunno about beer but mine (GT-I9100P) had a couple of vodka baths and it still works impeccably. (and when I say baths, I say full glass spilled on it)

Is there anyone who has an archos 70 internet tablet 250 gb with a broken screen and want to sell it?
i dont't have one - but it would be easyer to help u if u would tell wich part u need
i need the main cable that connects the screen with the main board thanks for your reply. i am searching everywhere
well that shouldn't be to hard...
they are called Flexible flat cable
u should get em on ebay or at your local electronic store
The only thing u have to research on your own is the connector type (at mainboard side). But that shouldnt be to hard - imho is should be one of the default connectors for those cables - even im not sure.
Maby "scholbert" knows... u could ask him.
Count the pins and try to buy one - no need for a full device
thanks for your advice but the this cable have other connection on it too is not so simple thanks...

well the picture is quite small - but I can see it's a bit different "style" then in my 101...
Anyway as there shouldn't be lines carrying combined signals - it still should be possible to rebuild that...
I fear that's the only way u have atm - since we don't know any reseller for replacement parts as far as i know - I saw quite a few people now asking for different things batteries, digitizer, display,...
But the only solution was to take it from broken device each time (besie I saw some sceen without digitizer around)
wich leads to ebay,.. but most time they are not "that" cheap...
yes i am waiting on ebay for something for me but may someone has something here
here is a bigger picture of the cable. i am going to take another picture where the actual problem on the cable is tomorrow.
here is my actual problem one of the bins in my Flexible flat cable is destroyed.
thanks for your help.
help!!!!!!!
any good news guys??????
This phone never went in water or even close to water but Bell refused to honour the warranty saying humidity wen't in the micro-usb connector...
Maybe it's me who don't understand how water detector works but in my mind, the water detector are all good and would be turned red if there was any water on it???

don't know what to say, the connectors may have corrosion on them due to high humidity or something else, it doesn't mean that your phone had to be submerged in water. the good news is that it's relatively easy to change that part yourself i have done it. look on youtube for some tutorials to be sure and you can go ahead and do it

seems that there are traces of water damage.
Lift all the connectors, including the black dissipators.
Take an old toothbrush and some gasoline/petrol.
brush the contacts.
Let dry (no hurry..)
cross fingers and start the phone.
Thanks for your comments guys. I've already changed the bottom part (sub-mainboard with the usb connector) as the samsung repair tought that it was the problem but it didn't fix the problem. I'm 100% sure the mainboard just fried. This phone never went to water so it's certainly not water damage and it stopped working while sitting on a couch downloading a torrent on it... So my first guess is that it overheated...
I Just can't figure why they refused to repair it under the assumption it was related to humidity on the usb connector as it never had any... really...
I mean, the water-detector is right under the usb port and isn't red so no water went there....
P.S. on the picture it's not corrosion but dust... I've posted it to make sure I correctly understant how the water-detector works... White with purple x is good.... red isn't... if I'm not mistaking....
Hey guys, long time reader, first time poster here (and it's a long one too).
My OnePlus X is my daily driver and I was planning on using it for some more years if this is fixable
Recently the USB port started to fail, so I decided to replace the part. A little setback was that i also had to replace the GSM antenna cable, which I had damaged during disassembly. So far so good, the phone is now charging again and reception and mobile data are working fine.
However, ever since the repair my Wifi reception has gone to ****, it is now so bad that it's pretty much unusable even when right next to the router. I've come to the conclusion that this is not a problem with the antenna cable replacement, as removing this cable only kills cell reception, wifi is unchanged. You can see the cable i'm talking about running into the long side of the frame in the bottom of this

, with the golden connector on the lower edge of the motherboard (the other side connects to the USB flex cable, under the metal housing on the right). I believe the Wifi chipset itself is contained within the small housing in the upper middle of the board, with the + sign.
So now on to my question:
Does anyone know where exactly the wifi antenna on this phone is located? I'm assuming that it is being routed into the plastic/metal housing cover that's over the mainboard. I've made sure that none of the pins on the motherboard that connect to the housing cover are missing/bent or corroded. I've angled them up a little bit and cleaned them with alcohol to ensure a good contact.
But still, no wifi. Is it possible that the wifi chip itself got damaged in the repair and is there any way to find out?
Hopefully someone here knows something useful, I would be eternally grateful
Did you ever find a fix? I am having similar problems for one plus 3t
No, zero news on that front. I did some superficial research but was unable to pin-point the fault. I had to replace the phone, sadly.
Hello, I just got my S9+ (less than a week ago) and I discovered after 4 days of use, a very strange mark on the screen that has no depth.

It's very noticeable when I try to clean the phone with a bit of water. The droplets pattern changes:
I haven't exposed the phone to any miss-use and I'm baffled by this, is hard to see when the screen is on but it's forever in my mind now.
Could this be the oleophobic coating or am I looking at something else?
Do you see the line when the display is turned on? Try to dial *#0*# and test the display. It seems like the oleophobic coating, because of the water, but I never seen something like that before.

It's very hard to notice when the screen is on in most conditions. I'm returning this phone and hopefully it will pass Amazon quality checks, wish me luck.
In all 10 years of having smartphones, I never had a phone with this kind of flaw.
Hello I am having the same reaction on my phone. Did you find out what it was?
Same issue here
Only visible with screen off in direct sunlight or water is on the phone
I returned the device with an attached letter to it where it stated what was the problem.
I got the return, no questions asked. I would recommend reaching Samsung or your retailer to get this fixed or another device. If asked, just explain that the scratch has no depth, so it couldn't have been your keys or something in your pocket, also stress your phone is new.
Similar issues were reported for the Galaxy note 8 and I found a YouTube video with an S9 and a similar problem.
If you don't return the device, I would expect the problem to get worse.
So, as the title suggests, I have got my hands on a Samsung Galaxy A10 (SM-A105F) which was stashed away because i was supposedly dead. The phone is able to boot up (the vibrator works during start-up), the charging seems ok (I hear a charging tone when plugged in) and a port is created when connected to a computer. Someone may have set an alarm which went off at effing 5am further proving that the handset is indeed working fine. However, the display doesn't turn on even after letting it charge for some time and I wasn't able to see any graphics either so I think that the issue is with the display itself.
I dont have a spare phone or LCD to test whether the problem lies with the screen or the display circuit. I found some reference info and tested the LCD connector for a secure connection and then checked for voltage drop on the pins. I have attached an image of the same; the values in white boxes are from the reference info while the black boxes denote actual values.

I continued further and tried hot-testing the phone and measured the voltages on the components according to the Samsung service manual i.e. LED_A_20V, VSN_5P5, VSN_-5P5 and VDD_LCD_1P8
All of them were out of range.
The service manual says to reball/replace an IC (U7006) but I believe the display IC (U6009) and/or related components to be the cause of the problem. Need some inputs before I proceed as I would like to rule out any other possibilities.
P.s- This repair is a challenge thrown to me by my cousin who saw me trying to repair my Samsung Galaxy Grand Neo!
Admin/mods, can you please move this thread to Device Repair?
Got this to work yesterday. An acquaintance from an online group on Telegram suggested I reflow or replace the backlight IC which seems to be the culprit.
I reflowed the chip and voila! the display came on without any problems. The touch works fine too. So, it was a good challenge as I learnt many new things including handskills when using a reworking gun or a microsolder pen all of which goes towards a worthy experience. The look on my cousin's face was priceless too!!
Onto the next one
