Want your opinion on this phone black screen issue (see picture)...

My wife's phone got water damaged a few days ago and I took it apart and removed as much water as possible and put it in a bowl of rice to set.
I finally tried turning it on today and it seems to work fine (I think, syncs etc.) except that the screen does not power on. I can see the backlights when I look at it from an angle so it appears to receive power of some kind.
I took it apart further to see if I could see anything and I found that on the display cable there is a black area which looks like it is damaged/burnt on the cable. There was also a little bit of black on the connector but I believe I got most of that cleaned off, but the area on the cable does not seem to be able to be cleaned.
I don't really know anything about electronics or parts of a phone and was wondering if anyone that did could suggest what my next steps would be to restore the phone/screen to operational condition? Part replacement etc.
Thank you.

It sounds like the chip connected to that cable got fried, hence the burnt spots.

If that's the case I'm assuming there isn't much I can do? I don't want to solder anything but could can replace anything that just snaps in.
Thanks.

Bump for last ditch effort to get some opinions before giving up.

Touch cover issues?

After having a duff sd slot on my original surface my replacement arrived today, all good, left it doing updates and installing my apps for a while, all was well, or so I thought..
The keyboard is now not responding after a while, connected, works, close the cover, open it again, screen doesn't come on, press power button screen comes on, keyboard not responding, close cover, screen stays active, disconnect keyboard and reconnect it and it works again..
Had a quick look through the settings and there's nothing I can see that relates to keyboard sleep or power management..
Tried it on my old surface and its fine :\
Wondering if anyone has seen or heard anything similar, otherwise another tech chat with support tomorrow...

You might want to try rebooting the new Surface, and make sure the connection port where the cover links up is clean, but otherwise I don't know what would cause that problem. I've had cases where the cover wasn't recognized, but disconnecting and reconnecting it fixed that.

Only issue I ever have with the cover is if I remove it while the tablet is sleeping and when it wakes it thinks it is still attached.

It's been rebooted many times so dont think its that, had a poke thru device managet last night and looked for power saving stuff but nothing relavant..
Connectors are all clean and it works in the old Surface.. :/
Maybe the keyboards just missing the tablet it came with lol

Still nothing, hard reset, power offs nothing, have now noticed that the edges of the touch cover are peeling apart at the corners so might get this replaced as well, so far the support guys have been spot on, the device however while really promising just lacks finish :\

Two options....
1. Return the cover..
2. Bring your surface bad cover to Microsoft store and let them figure out what is wrong...
I am very happy with my surface and the touch cover...

I have a 5 second delay sometimes when opening and closing. Otherwise, ref let msft know

I've had 2 bad units now, don't think its the cover as it worked on the first surface before I returned it.
I'll get onto surface support when they are back, I don't seem to be able to raise a ticket on the new unit, touch cover might end up going back as well at this rate...

I've had the same issue with the type cover. Sometimes it works fine throughout. Other times it seems to fall asleep until an adjustment is made.
I've caught the connection off by a few millimeters at times (although that doesn't explain why the initial connection would work), but you can look and check for that as well.
From now on I'll simply restart from the Power button without removing the connection to see if it's really a 100% mechanical issue.

Ha I've had all of these problems you've named

On Live Chat with support now, the MS forums seem to suggest a reset, I've tried it a few times tho, will see if they will fire out another cover..

Right, cover is being swapped out on AR as well now, hope they hurry up and take the hold off the card though, the hold is for more than it would cost to actually buy the bloody thing new again..

Weird fault with Note 10.1. Help!

Hi guys, newbie here, and im in desperate need of your help!
So I decided to buy an Note 10.1 and yesterday I received it. Straight away (after turning on) I noticed this rather irritating noise (like a notification sound but not one that is the ringtones options on the tablet) that the tablet made when I held it with one hand well, at first I thought it was a motion gesture since whenever I hold it with one hand (the right hand) it switches to the previous app if your in an app, or previous Web page when surfing the net. So I searched the options 100 times, and nothing to toggle off.
Anyway it bugged me more and more and I couldn't figure it out, then by chance i just pushed slightly on the back of the tablet and the notification noise goes off. Push again, it happens again. I decided that it could be a loose connection being made and remade every time I decompress the right side back panel (I can play it like a piano). So I took the back panel off (a pain in the ****) and noticed a ribbon cable that runs directly where I push the back panel (the S pen sensor cable). It was plugged in correctly, but wasn't taped to the battery like the 2 fatter ribbon cables.
So, I taped it down thinking that me pushing the back panel was moving it and creating a loose connection. I thought I had solved it. Booted it back up, no sound!!!!! Reinstalled the back panel, booted again and BOOM, the sound returns.......
Gutted.
Not sure what to do next, it definitely sounds as if something is disconnecting and reconnecting like a USB on a PC, im getting the sound but no notification or error. I have no idea why this would make an app switch to the previous app or webpage when on net.
Any help would be much appreciated.

Well, it seems I have solved the issue. Since this is a new account, I can't post youtube videos. So I'll leave those out for the time being.
Firstly, heres a video showing the fault. As you can see, I've narrowed it down to the docking station/charger connector.
The ribbon cable was seemingly depressed causing it to disconnect briefly before reconnecting when released. Probably the down side of having a flimsy plastic case.
Solve the issue I removed the ribbon cable and taped a small amount of foam right at the mouth of the connector, making the whole connection sturdier and harder to depress with the cover on, which can be seen here.
Hopefully this helps anyone who finds themselves with a similar issue.

that woulda went straight back to the store

Yep, if the problem isn't fixed there's no way it'll get fixed under warranty now...
If the device is less than a week old, in Oz, the shop is supposed to replace the device immediately. This doesn't mean they won't try the old "It'll take 2 weeks to fix" and "It has to be sent back for repairs" schtick....

I got it from Ebay, although it was listed as new/unused.

USB Power Connection

Has anyone had any issues with the connectivity of the USB port when trying to charge? Mine doesn't always charge; I have to find the right position for it to make correct contact (it doesn't seem loose either). I've tried different cables and I applied a couple bursts of contact cleaner to it to see if that would help as well--no go though. Any ideas?

It's breaking. It's difficult to fix. You could see if someone will try to fix it for you but they gotta be pretty good. Otherwise invest in an external battery charger.

Bummer... I'll try and look for some kind of guide on the net. I've fixed other electronic devices in the past, so I'll give this a whirl... Thanks for the reply!

Godspeed! What happened to mine was the traces broke off from the motherboard so I had to re-attach the connector. The connector itself was still in good shape though. It was quite a challenge.

Thanks! We'll see how it goes...

Are you seeing that the battery is intermittently charging when plugged up? My wife's phone is having issues and I have isolated it to the most likely culprit being the USB port, though the port is not lose and I have cleaned it out. All I can figure is that it has bad connections with the motherboard. Phone works fine if I externally charge the battery and insert. Wanted to see if you were seeing the same sort of things. At this point, for $139.95 and free shipping, I ordered a Blaze S 4G from Amazon for her, and will likely give the S 4G to my daughter to play with.

Yes, it'll go in and out of the charging state; but when I put it in the "right" position it'll go back to charging. I opened it up to see what the deal was and everything seems fine. However, I did get a chance to compare it to a "working" one and it seems the metal port housing is a little bit out of whack. So when I get some time I'm gonna see if I can get it back to normal--the metal seems a little flimsy.
Here's a really good guide that I used to take it apart: http://www.youtube.com/watch?v=qMOdkBadlJU

Mine is doing the samething, 5 use an external charger with two batteries. I also use a different phone to upload roms, or anything else to the micro SD Card. Seems to work just fine.

Just got mine back from Josh over at mobiletechvideo. 35 bucks to change port. I couldn't buy a decent soldering iron and the part for that price.

Glad you got it fixed!
Another problem may be the USB cable itself -- My beloved OEM Samsung 2-meter cable doesn't work reliably any more, it needs to be "drooping" a bit to make contact (in any device).

Dropped my P900! Blackout!

I just dropped my P900 and it went completely dark. :crying: There's no mark, not a crack, nothing, but the display is completely dark. The touch buttons on each side of the home button lights up, but the display does not.
Any advice? Or it is Samsung support next?

May the ribbon for the display is disconnected from the circuit board.

Yeah, maybe I should open it myself and have a look. Are there any warranty seals that I will break if I pry it open? I have all the tools necessary, but are there any guides for opening the P900? I wouldn't want to break anything...

This is a video on replacing the battery but it helped me when I re-soldered the battery connection on mine.

I've opened mine a few times and haven't noticed any specific seals but mine was refurbished to start with.
Also I have the proper tools but found a guitar pick was easier to use personally on this tablet.
Starting at the power port to remove the back made it a lot easier for me, its pretty hard to get anything between the back cover and the tablet in other areas.

This was indeed the problem! The connector has some kind of snap lock that had come loose. So easily fixed. Thanks for encouraging me to try to fix it myself. :good:

Glad I helped!

Sorry to hijack your thread but figured my problem might be related.
About 2 weeks ago I charged my tablet and stored it away. The other day I tried to use it and it wouldn't turn on. I tried to charge it but that didn't work either as there isn't even charging activity on the screen. I ordered a replacement battery thinking it might be that, but I was wrong. I still can't make it turn on. Any ideas what it can be? Thanks

I had a similar experience. 3 weeks ago the 1x my SM P-900 is out of its protective case, it falls 2.5 ft off a table. Hits the floor. No visible cracks or breaks. I could hear hear it operating but the screen was black. Took 3 weeks to talk myself up to it but I pried off the back & used a magnifier glass to c.a.r.e.f.u.l.l.y check every ribbon connect. 1 connector's pins were very slightly off alignment. Couldnt find anything else. Put it back together...Yes! Screen works. All seems good. Took the back off again & securely taped over every ribbon connect I could find. Long time intermittent screen flicker issue (when battery was below 40%) also seems to be gone. That has been the best, eye squintin', back hunchin', shallow breathin', micro-screw wrangling, time investment my non-hardware tech self has ever spent. Wooo!
