Hi,
My phone has a problem, i hope someone can help me, it started about a month ago,
When i slide the keyboard the screen would freeze, the image would freeze or sometimes it would become like this:
http://www.esato.com/board/img.php?id=140762 ( this is not my phone its just a pic i found)
This problem would be solved it i gently slide the keyboard back in, the screen would be back to normal, sometimes i had to slide it out and it
alot of time to make it work.
Well, today i woke up, with the screen of my phone all messed up ( like in the picture), i slide it out and in alot of times but no luck.
I turned my phone off, when i turned it on, the screen doesnt lighted up or showed something, the phone just vibrates, i took off the battery and tried again but no luck.
I read somewhere that i could be the flex cable, so i ordered one, but its gonna take some time to arrive.
Anyone had this problem before that can help me?
I didn't encounter such problems on MT4GS yet. But being a slider phone enthusiast I could 100% say it's a flex cable thing since I encountered that problem more than a dozen times already on other phones(nokia).

I would strongly recommend that you get a cable with the speaker already soldered in place....
+1 to that, get as much pre assembled as possible, this is about the most pain in the butt phone I've ever had the pleasure to disassemble. Read the last few posts here!

Yup. That one has the speaker, it's the black bar at the top with the silver sticker.

thanks for this bit of advice.
Disassembling the front of the phone is a pain. I'm a fan of spending $40 on ebay on a broken phone (where the screen still works just fine) and swapping out the fronts. That will get you a new flex cable as well. Otherwise, you risk having to get a new flex cable *and* a new LCD.
Agreed. First time disassembling front I was scared not to OVERheat phone internals. I ripped in half trackpad ribbon, damaged lcd back cover and got a lot of problems from it.
Then I bought broken phone with good front, but dead LCD. Second time I just lost it, I heated phone so hard that I got burns on my fingers, but it was worth it, LCD glue came off soo nice.
So better to overheat, then underheat when disassembling front LCD.

Cracks are not always visible. But if they're not there, I'd suggest you open the back case and try to reseat the ribbon cables at the touchscreen PCB. While at it, check the flat silver cable connecting that board to the mainboard also. Make sure nothing is jarred loose by the drop.

thanx for responding...i did exactly what you said ..i disconnected both cables (silver and brown) and put them back..more than half of the screen started working, the other part was just dead and those parts didnt work even when i tilted the screen.. like 5 minutes later the entire screen is dead again......do you think its the digitizer?

Sorry for the late reply. I've run into this problem before. When you have a digitizer that works for a few minutes then stops as the tab warms up, (1) more likely than not, there's a crack somewhere or a tear on the ribbons, visible or not, or (2) the new screen boycotting the old firmware. No new screen points to faulty hardware. However, it doesn't hurt to eliminate possible software causes.
The best test I can think of at this point would be to first check the physical connections again (check the connectors and ribbon ends under a magnifying glass, make sure they aren't damaged, bent or stripped), then re-flash the firmware following instructions in another thread, then turn on "show touches" in settings. If you still see "ghost touches" after a few minutes, the digitizer is likely ass-kicked by the drop.
I've had a digitizer on a TF act "leisurely" because of a crack across the width of the bordering black strip that couldn't be detected with the naked eye because it severed the circuit on just the underside. The surface was totally smooth. As the crack spread, it became obvious.
If I had access to your glass, I could've tested for you. Too bad.
A friend of mine had a Galaxy S3 Amber with a broken (and blank) screen and wanted her data from it's internal memory that is locked and not in debugged mode. I did a lot of research and found the best, most efficient way was to do a motherboard swap with another gs3. I had a Galaxy S3 Blue. I watched a couple of videos and it seemed rather easy. I gathered the proper tools and was EXTREMELY careful not to break or rip anything (and to my knowledge i did not). When i put her motherboard from the amber one into the blue one and the screen would not come on. My first thoughts were it must be her motherboard that went bad. Well when i went to put my blue gs3 back together (again being very careful this entire time) I'm now having the same issue as she was. Black screen, no back light. The bottom lights DO come on and i feel it vibrate when i get a message. There was also no power on chime...
I know its hard to tell with out looking but any ideas on what could be wrong or what i might have screwed up? i checked all the connections and everything looks perfect. Nothing is bent or connected wrong and I didn't force or break anything.
update: so i found that the touch part of it still works fine. i can hear the ripple unlock as well as all the other sounds and such when i touch around and i can here it opening apps. the only issue lies in the screen itself being blank with no back light what so ever,
First of all remove the battery and attempt to power on, then leave without battery for 1 min, I know this sounds silly but it worked on an old iPhone 3G so anythings worth a shot.
If that doesn't work go back into the S3 and make sure all the data clips are firmly in place and locked down but not twisted in anyway. Also make sure their is no moisture or dust on the ribbons. You may not realise it but even the smallest imperfection with this can cause massive issues down the line.
If all else fails her phone may have broke your screen, I don't know how but it is a possibility
Hope I could help and good luck

so i took it apart again today to double check and clean everything and under inspection i noticed a teeny tiny slit on the edge of the lower, bigger ribbon. i know the smallest bit could be horrid. Any fix and would that cause just the screen to not show? i don't know if that is the led connection but i think it may be.

If theirs a slit I'm affraid that could be it for the screen, like I said even the smallest imperfection can cause massive issues. The slit is probably in the one of the data sections of the ribbon cable which is why data for the screen isn't being carried.
For the fix I don't think their is one unless you can fit a new ribbon on to yout S3's screen
Sorry about the screen
So I took it all apart again. Cleaned ever little thing I could and now it works again. ?

Hey guys,
last night I decided to replace the back cover of my Xperia Z3. I've ordered an original one and got to work. First problem is that it won't stick - the adhesive sucks. Shall I heat it up with a hair dryer or something? I don't want to damage anything inside the phone itself. And here we go to the second problem - after installing the new back cover the vibrations stopped working. I've performed a full wipe, reinstalled another ROM (wiped System, Data, Dalvik and so on) but it still won't work. Since it's a hardware problem, which part shall I check and then replace? The buzzer itself or maybe some connections?
Thanks in advance
Anyone?

Z3 shares same flex cable for the power,volume buttons, lcd and vibration so u need to check the flex cable.
I recently replaced mine due to stupid service center people refused to entertain my warranty.
If you not so sure, u can take help from professionals.
And you can get the adhesive online somewhere if you damaged the supplied adhesive with the back panel.
Also be very careful while putting that adeshive first put on the panel and stick the panel to phone back.
Gud luck..

Thanks, I just ordered the flex cable yesterday after some reading and I will be replacing it today or tomorrow. My warranty was refused due to me replacing the back panel on my own :good: Thumbs up for all the warranty services. Soon we won't be able to change wallpapers without getting our warranty void.

you sure the flex cable is not faulty?
also try to diagnose the vibration by system diagnostic.

It was brand new and everything else works.
EDIT: now the upper part of the screen won't work... Today is just one of those days... I changed the flex cables back and forth - same issue. No vibrations and no upper screen reaction. FML.

Can u check with old flex if the screen is functioning if yes then your new cable must be faulty.
I had no such issues, and since you yourself opened the device it should not have any issue with motherboard

I switched between flex cables and the problems persists. I've been sitting and trying to fix this with various ROMs, cables, buzzers and other things for 8 hours now. I'm gonna reassemble the phone as carefully as possible, flash stock ROM and send it to Sony again. Maybe this time I'll get lucky and they won't see that it's been opened... I don't feel like spending 300$ on fixing it on my own.

Were you ever able to fix this? I had the same exact problem as you, replaced the LCD/digitizer on my Z3 (D6603) and then re-installed everything and now my vibrate motor doesn't work. I bought a new flex cable/with vibrator motor, installed the new one, but the same problem occurs. Vibrate doesn't work at all.

Unfortunately, along with the vibrations, also my screen stopped working. I gave it to the warranty service, where they told me it's my fault, cause the damage is mechanical (how? I have no clue, cause there was not a single scratch on the phone) and they proposed a repair that would cost 110% of the phone's market value. I simply sold it for parts on eBay and bought an SGS6 Edge. No more Sony for me - their support sucks ape balls.

I can confirm the fuse fixed my buzzer.
My fuse had blown open somehow so I replaced it from a donor board and now it vibrates as it should.
Oh it's just above the clip that holds the board in place to the left of the large cable j-tag connector for the on/off vol camera and buzzer/vibratorView attachment 4720024
Yes that's the Z3 dual but is the same for the D6603
And he sold his phone by parts at last
Lol ?.. ......
I enjoyed this a lot

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.
https://www.youtube.com/watch?v=VeSG0hHpAG8
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!
