Hi, I come on here quite a lot for information as it's an amazing resource! This time however, I'm attempting to give something back!
I experienced the "black screen on slide out" on Monday. Phone completely screwed. I've also had a few droppages and had it apart once before so there's no way warranty is gonna help!
I stripped it down and soon discovered what it is that actually fails on the ribbon. The coating had worn through due to rubbing on something during the slide out / in process. it had been playing up for a while, probably due to shorting out on the metal case, but now the tracks (aluminium?) had worn right down.....
In pic 1 i've circled the worn area. The shiny section is where i'd tried taping over it to prevent shorting, before i realised the tracks were gone.
Got an almost new one off ebay for 15 quid and, realising it was going to happen again, came up with a solution that, so far, looks like it will work....
A while back I bought some "anti rattle felt" for my car's dashboard - really thin and strong self adhesive felt to prevent squeaking joins between dash sections. I cut a piece of this and stuck it to the new ribbon. Once this stuff is on it's well stuck, by the way!
See pic 2 for the modded ribbon cable.
On reassembly everything is working just fine so far! Here's hoping that it lasts longer than 6 months this time!
Just need a new casing now as mine is decidedly second hand!
Hope this turns out to be of use to someone!
cool story bro
when i took apart my xperia to replace the housing this seemed like a really weak point in the device. glad to see someone who has had the problem has been able to fix it
Why does the screen go black?
Hi,
When the coating wears off the ribbon cable it exposes the tracks in it. when you slide the keyboard out the exposed tracks short out on the metal casing and the screen loses it's input signal.
thats whats happened on mine at least and i presume quite a few others?
HTH!
Update:
That's interesting: My phone was also losing signal with the keyboard out, and occasionally while closed up as well. It would just randomly drop to "no signal" for a few seconds.
It hasn't done it since replacing the ribbon cable.....could be coincidental of course.
I'm having the same problem
It just started a week ago and I got the phone in January off of ebay. I'm new to opening up the phone so could anyone help me find the correct tools or have a link to a site with pictured instructions?
I noticed that the sliding mechanism started to go loose about 4-5 months ago but didn't expect the screen not respond in landscape mode. I have yet to see the other symptoms you all are referring to. I would like to fix this before it get worse.
In mine case it went totaly black after one week of this problem... You have all the instruction on youtube, there is where i looked. For tools you can be inovative, but the exactly right ones come with housings from ebay, it is only 15EUR, and i bet you have some cracks so it wouldn't hurt replacing. That is what i did, along with ordering new sliding mechanizm, and new ribbon cable.
I am open for ideas to prevent my ribbon cable from being cut at it weakest point again.
I'm assuming my flex ribbon went bad yesterday, since sliding the keypad out causes my screen to shut off.
Already ordered a cable off ebay and will attempt to replace it myself :O
Replaced my flex ribbon cable with one I bought on eBay. The screen doesn't turn on at all now, which leads me to believe the cable I was sent is defective. Put the old one back in and it works okay, less landscape mode. ughhh what a pain.
great tips! my input is I bought a case off of ebay that was ~60$ and everything actually fit fine for me...so I wouldn't discount every seller but you do get what you pay for, the 15$ cases are probablly the ones that will give you problems
I working in a mobilephone repair center if anyone need help drop me a priv... i able to get 2nd hand or even brand new components
Replaced the flex ribbon cable -
I got my flex ribbon cable a few weeks ago and took it to my local repair shop. They replaced it but the LCD screen/optical joystick receives no power. The touchscreen and everything else on the phone works just fine now. I thought it was a defective item so it was exchanged with a new one.
Got the repair shop to replace it again and the outcome still remains the same as the first.
Theres no light coming from the screen nor the side illumination.
I just told the repair shop to just place the original back in for the mean time.
Before the repairs, there would be a flicker of white light and random illuminations. Now there's no lights at all except the power botton.
Could it be defective a batch that the seller was sending out? or the repair shop's mistake and is playing dumb so they do not have to admint fault?
Hopefully there's an easy fix to this problem.
-Also I did inspect the ribbon before and after the repair. looks new as the OEm
Can anybody help me out with this new problem after replacing the cable -
perhaps you should try a hard reset. Ive had problems in the past where the optical joystick and the illuminators did not work, and that worked for me.
On the other hand, the top illuminators are on the same piece of hardware as the flex cable that was replaced, so a faulty flex cable is possible. The bottom illuminators are on the circuit board that the optical joystick attaches to, separate but connected to the flex cable.
Ive recently replaced my flex cable and touchscreen. The experience i had with the faulty touch screen was that it appeared to receive no power, but was in fact displaying a dark backlit illumination that could only be seen in the dark. At the same time however, the screen did not display anything. I'm not sure if this is similar to your experience, but if so then your touchscreen would need to be replaced.
ive done all repairs on the xperia myself, and one thing ive discovered is if something doesnt work right after a repair, simply disassembling it and reassembling it to make sure all the connections are properly done has worked for me in the past.
"Before the repairs, there would be a flicker of white light and random illuminations. Now there's no lights at all except the power button."
Now when you say the power button, do you mean that a red light appears under it?
I dont know if i can come to a conclusion or that i can help (or have helped) you come to a conclusion, but i can only assure you that the xperia acts out in strange and weird ways.
Good Luck!

Thanks for the links. I've tried the hardreset and restoring the original rom but the issue is still there. It's really bugging me that everything works but the LCD screen. I'm currently using MyMobiler to use my phone. The touch screen works fine and so does the soft keys. Just no power for the lights. I might just give up and wait for another phone that catches my eye and then tinker with the xperia myself. but if anyone got a solution or want me to test something then I'll give it a try.
My warranty is no longer affective so I'll use my phone as a tester to help others with any problems.
TRIONDAVE, how's your Xperia running now with the cable mod that you did? Its been 6 months since you created the thread. I hope you're still around.
My Xperia X1 works nearly fine, except for the keyboard issues, so I'm thinking of opening it up. If your Ribbon mod helped I might just do it too once I've got it opened. Mine has a MOUNTain of cracks though, and the battery compartment itself is cracked on both side enough to make the compartment CURVED. Hence the Battery cover doesn't sit well.
I'm looking around for broken Xperias which I might be able to use to change the internal cracked casing. Lets see.

My thoughts exactly.
Hello guys, I am in need of real help over here!
Its just that Ive replaced my ribbon cable, the old one got screwd up.
However I got done for 10 minutes ago, tried to start up the phone.. without success :,(
The ribbon cable doesnt have anything to do with the start up, only the screen am I correct? Cause I cannot even start my phone..
Ive connected the charger, but when I remove the battery it shows a red light, meaning no battery, correct?
So what may the problem be exactly? Maybe the battery is all dead, or?
PLEASE HELP!
for the people with ribbon failures how long have you had the phone before it occurred ? im just interested on the cables lifespan.
mine is fine so far but i have noticed the slider is flimsy and rocks left and right.
I was tapping out a text when all of a sudden the screen went black. the capacitive buttons still light up, but absolutely nothing from the display..
I'm kind of at a loss for what could have happened. the flex cable looks good and where it should be and doesn't appear to be loose...
Oh, and the digitizer still works because I can go through the motions of the lock screen and the phone vibrates.
open it up and make sure the connections on the flex are good, might need new flex cable and/or lcd
I tried to file a claim through Asurion and they said it wasn't covered! Kind of baffled at that. So I went in to my local Tmo store... renewed my contract, but made my bill $10 cheaper a month, and they were able to do a warranty replacement and I'm getting a MyTouch 4G Slide
Same thing just happened to me, I left the keyboard open for 10 minutes and when I came back it had a black screen (not off just black) can't get it to work. Im gonna try to take it apart and reconnect the flex cable. Ill let you know if it works.
G2 Black Screen
Hey, did anybody find a solution to this? I bought this T -Mobile G2 used so I have no type of warranty. The screen stays dark, but vibrations, ring tone, and the lights behind the"home& menu screen at the bottom work. I replaced the screen/digitizer but this did not fix it. still the same. what else might be wrong?
---------- Post added at 03:02 AM ---------- Previous post was at 02:06 AM ----------
okay well I just found out that LCD screen replacement part and screen digitizer part are different. so I have purchased LCD screen. Will update whether or not this works as it seems through my internet searching many people have had this prob with the G2.
I have the same problem, black screen, touchscreen works because I can feel the feedback when I unlock. I've also done lcd replacement. That didn't help either. The only way I can get the phone to wake up is by squeezing the top left corner in the area by the proximity sensor, and the power button at same time. Doing that it takes me like 10 tries to get it to wake.
well you probably either didnt get a good connection at one of the cable points when you replaced the lcd (open it back up and check this) or you need to replace the entire flex cable
This happened to my sister's Desire Z (except she dropped it). Screen was black but phone was working. I reseated the LCD flex cables but that didn't fix the problem so I replaced the LCD module thinking it was dead. The screen was still black so out of desperation and anger I gave it a hard smack and it started working. It has been working for three months now. Go figure
Original LCD was probably good and the issue was probably due to a faulty flex cable, however on the DZ these cables are pretty complex and expensive (costs more that the LCD module)
Hi all,
I sucessfully changed my cracked digitizer on my Nexus 7 gen 1. Followed the procedure in youtube and heated my screens and used guitar wire to remove the cracked digitizer-looked good.. Cleaned up the glue on the LCD and and taped the LCD to the digitizer. I did not glue the LCD to the digitizer. Reasembled everything and booted.
I booted and everything booted correctly. Except for starting. I had to drag the lock icon over to the right to open the tablet. Swiping did not work.
The digitizer does not work with swipes. I had to touch several times to even get a response. I could touch a icon app to start it but could not turn pages if I needed to. I thought the digitizer electronics was defective, so I bought a used motherboard(suposely 100% tested).
When the new motherboard came, I rassembled everything.
I powered up the new motherboard. Half of the screen had sigguily lines and I could see the boot up icons coming up on the other half. Thinking I did something wrong, I pulled the battery connector. Rechecked all of the connections, and pushed the start button. Nothing happened. No light of any kind.
I reinstalled my original motherboard and same thing, no boot up at all. The only difference is that with my original motherboard, I heard a "bonk" sound from the speaker 3 seconds after I push the start button, but nothing on the screen.
Any suggestions from anybody? Maybe bad LCD connector. If the connector is bad, would that prevent booting?
Anybody seen this before?
Help!!!!!!
Steve
Leave it charging for half hour and press power button for 10 to 15 seconds and it will boot
Hi all,
I think I found the answer already.
My LCD flat cable is broken. Using a ohmmeter, I found most of the flat gold traces have a break in them. Probably from my dis-assembly of the
and assembly of the LCD too many times. i am ordering two LCD cables from a China distributor.
I hope it fixes the problem, I have not received the cables yet.
But the question remains. Does having a bad LCD cable prevent or stop the Nexus 7 from booting?
Steve
Ok, so my G2 died the other day. Well, it still works great, but the screen went to white fuzz... like what you used to see when the rabbit ears on your Tube TV didnt get any reception. Static fuzz, but thats all it showed when i powered it on.
The phone, that day before it broke, was on the boat and got really hot. Once it cooled down that night this happened.
In my grand fix it fashion, i opened the phone up wrong and ripped the LCD ribbon off the screen. Blah. So I just ordered a new OEM lcd panel/touch digitizer kit from ebay.
Popped that in the phone, and behold, it booted to the LG logo!! then the logo went out. That was that, just a black screen. But the phone still was working, i can hear it boot up and receiving texts.
I tried to boot it a few more times (disconnect the battery, reconnect, boot). The LG logo comes up, then goes out.
I found out if i let the phone sit for 30min or so, it will actually boot just long enough to hit the desktop and it seems fine. But it wont respond to touch at all, then seconds later it goes black again and thats that until I let it cool.
There is nothing else apparently wrong. It just wont respond to touch at all and the screen blanks out soon after boot. Its definitely some chip heating up too much and failing. I see on the main ribbon assembly, the one that connect the LCD to the mainboard, has some chips on it... it reminds me (A LOT!) of the TCON boards on LCD TV's. When those go bad, the TV still works fine but the display is all messed up. So I ordered that assembly and it will be here in a few days... but has anyone seen this before? does that ribbon assembly really ever fail? Again, the motherboard would be the only thing left, but that does still boot and work... I haven't tried connecting it to a TV but i wouldn't be surprised if that works... it just doesnt display anything on the phone's screen.
cable assembly didnt work :/
ordered a motherboard. this will be a practically new phone by the time its working again... if ever...
SUCCESS!!!
New motherboard installed. Finally boots and works properly. Well, it sort of has to, because there wasn't much left to replace! New screen/digitizer, ribbon assembly/charger port, and motherboard!
Just did the manual lollipop update!!!!! I got my phone back!!! screw you crappy 4" backup that i hated!
Touch screen unresponsive -> Inserted new LCD+digitizer -> touch screen unresponsive
My friend's Galaxy S4 i9505 had a crack in the glass and he asked me if I could fix it, so I carefully separated the glass from the LCD and glued a new glass on it using Loca UV glue. At first glance the result was absolutely great, but when I powerd on the phone again, the touchscreen suddenly was unresponsive. After re-checking al connections over again and resetting the phone back to factory defaults, the touchscreen was still unresponsive.
We decided to order a new LCD + digitizer unit from a Chinese Ebay seller with 99% positive feedback. After about a week and a half it arrived and I moved over parts on to the new screen and installed it very carefully. After checking all connectios and booting up the phone I unfortunatly noted that the touchscreen was still not functioning.
Now I really don't know what to do anymore, since the new LCD's touchscreen (digitizer) can actually be a D.O.A. what I would find bad coincedence or there is some sort of problem with the phone's mainboard wich would be bad luck.
What do you guys think? I am really not sure now. I will probably contact the seller of the LCD and try if I can return it and he will send me a new unit (No money back guarantee :crying: )
Maybe there are some other options left? Any ideas, please?
EDIT: Problem solved. Repairguy discovered that a small chip on the mainbord was damaged. He replaced the chip and now the phone works like a charm.
I had a similar problem after replacing my entire front assembly housing (preassembled glass, digitizer, LCD, frame). After I got everything transferred over from the old one (vibration motor, front camera, earpiece, headphone, motherboard, antenna micro-coax cable, lower bezel control ribbon), hooked everything up, screwed rear housing back on, reinserted SIM card & SD card, reattached back battery cover, powered it back on-- then to my horror, there was ZERO touch input response on the touchscreen. Panicking for a few minutes, started planning on moving everything back to an old Android (S3) phone, then thought to try a reset first-- I pressed the up volume & power buttons, got into recovery mode, then selected "wipe cache partition", then selected "reboot". After it restarted (and holding my breath), VOILA it worked! Touch input was restored, Hallelujah!
Just commenting here so I remember where this thread is.....lol
I'm going to be replacing the screen on my son's S4 when he's saved up enough money to buy the replacement screen......
Does anybody know if (in general) ebay purchased screens are reliable?......
