every so often whilst my xda mini s is doing something , my screen is covered in lines, i then press the power button to turn screen off and on again then its fine.
is there a way to perminately stop this , or what is the problem behind it.
thanks
Hi,
I had a similar Problem (vertical lines) when i pressed the screen/O2 logo in the botton right hand corner. (after holding it down with the lines on screen the unit crashed after 5 seconds or so)
Went through various options, originally thinking it was a software problem, however I think it was that the screen ribbon connector (ie the bit on the circuit board) was shorting out with something (not sure what).
Reason 'I think' is that after taking My Mini S apart (good tutorial on here somewhere) and placing 1 layer of Sellotape on the non conductor side of the ribbon before pushing back into connector (to improve connection) and covering every circuit board that has components that are close to anything conductive (metal) with insulation tape it seemed to have solved the issue
This is after I had replaced the screen circuit board (which contains the connector), and played about with various other options, putting them all back when they did not work.
Now taking it apart is no mean feat and you may damage things (as I had a 'spare' which is really dead I wasn't too worried as that was used as the test!)
If they are horizonal lines I do not have a clue, sorry!
May help. may not - I Tried
yeah, the lines are vertical , so it could be down to poor connection.?

Hi all,
I have an O2 XDA II which was flashed last year to WM2003se.
Now I would like to upgrade it to WM6.1, but I cannot enter bootloader mode (using [Power Button] + [D Pad] + [Soft Reset]) because my power button is broken. This means, I also cannot do a hard reset, unless I remove the battery for a long time.
The phone otherwise is working quite well.
Is there any other way to enter bootloader mode?
Thanks in advance!
First, some advice. Several people have asked this question and it has been responded to in other threads. On forums, ALWAYS try and use the search function before asking. It might save you some time, and it also may give you further ideas or solutions to the problem. Now on to the response I gave someone else last year. Read the whole post.
IT IS POSSIBLE!
BUT DO THIS AT YOUR OWN RISK!!! I'M NOT RESPONSIBLE FOR ANY DAMAGED OR FRIED PDAs
I know because I myself have done it on an I-mate (Himalaya). It took some trial and error but I am now running WM6. In my case though, I had to completely remove the power button from the device. The previous owner dropped it on its head, and I got it for free, unfortunately most of the top is missing, including the power button.
SO, on to how I did it. I took a paper clip (metal) and put it about 1cm down, slightly to the right of where the power button used to connect to the motherboard. Make sure you have turned your XDA/IMATE on before doing this. You'll find that when you find the right area, your device will turn off, or the screen will go dark (like holding the power button for a second or giving it a quick tap).
If you manage to hold it there for the right period of time, while pressing the other bootloader buttons, then you will be able to enter bootloader.
This took me close to an hour to get just right, on both occasions I have done it, but it eventually worked.
Note: I have no idea how exactly this worked, but it did. My IMATE was useless without me updating the rom, so I had no worry about frying it if I did something wrong, that is why I was OK with playing around with its insides. BEWARE that you MAY DO DAMAGE to the device.
Good luck.
Hi my power button is broken too.
I'd love to upgrade to WM6 but can't get into bootloader mode...the paper clip approach sounds risky!
Is there an application that can get me to bootloader mode? I've searched but come up with nothing.
Any ideas?
I tried everything before doing the paperclip trick, it was the last straw for me. I did a pretty intensive investigation to other possibilities but couldn't find one.
Maybe you can find something that was a similar shape to your power button? It is a long shot but it may work. If the power button isn;t completely broken off you may still be able to use it.
Thanks Jadel.
Naaa the button has completely come off.. on its side..facing the front of the XDA. Interesting to see that other people have damaged the power button.
I might give it (the paper clip approach) a go and see how it goes.
Thanks,
Taz

Same power button problem here... I found this thread and it inspired me to another idea that works very well. I disassembled the unit according to instructions I found here in other threads. I found my button was broken off from the motherboard completely and in addition it was mechanically so damaged that is was unusable for resoldering. I disassembled the (very small) switch under a microscope and it is basically a small round steel disc that works as a spring. It "clicks" when you push the center of the disk. In the center of the switch is a contact point so when the disc is pushed it makes contact and when released it clicks back. (works like the clicking frog we used to play with as a kid). It solders onto the motherboard using 4 solder pads. The two top pads are both connected to the ground plane of the motherboard. The bottom ones are 2 separate contact islands and are not connected to each to each other. (infinite resistance between them). I soldered 3 wires onto the pads, one ground and both lower unknown contact pads. Brouhgt the wires out through the broken button hole in the cover and YES, it works like a charm. If I connect the ground wire to the lower right pad it switches on and off and I can also hard reset the unit. I have not found out what the function is of the other (left lower pad) connected to ground. Maybe it has to do with holding the button longer then a second to switch backlight on and off. In my case I cannot find any functionality. I can now manually short the wires or I can solder a small microswitch to the wires and flash my original QTEK 2020 to WM 6.1. I am going to try that this week end. Anyway no unreliable fumbling with a paper clip.
So, being clumsy, I left my Streak in my hoodie pocket. Well, we can all see where this would end badly once I bent down to pick something up. I did, dropped my phone and cracked the screen.
I quickly went and bought a replacement glass + lcd display, and replaced the unit. But, upon turning the phone on, I noticed if I hit it a little too hard on one corner, It would restart, and the vibrator motor had ceased to work.
So I figured, hey, I'll just rebuild it again. So I took it apart. Looked through everything, took my time in putting it back together, because maybe everything wasn't fitting snug.
Now, When I turn it on, every thing is on, buttons light up, and the screen is lit up, but it is black. I never even get to the Dell logo. After about a minute the buttons dim, as if in idle. So i believe the phone still works, but maybe the connections on the MoBo is faulty? Any help would be nice, thanks.
check to see if the ribbons are snugged in place.

I agree take it apart and chech your work. I had problens with my camera and flash. It was tge connector not being fully seated
Sent from my Dell Streak using XDA App
Well, I just took off the rear cover and reseated all 3 connections, pushed em in as smoothly and far as they would go. But, same thing. Black screen. But the LED is still working...
I'm having the very same problem. This is my second replacement screen and neither displays anything except black screen with backlight on, and the home + settings + back buttons remain lit. I can hear my phone starting up and receiving messages, but I cannot see anything. I've taken the phone apart and put back together five times between two replacement screens.
Does anyone know what ribbon cable might be at fault for this particular issue? The largest ribbon cable was shipped bent across the circuit board on both screens; there is a permanent creese in both ribbon cables, but I'm not certain this is causing the issue.
Any insight or assistance with this issue would be greatly appreciated!
Hello everyone,
i need your help in a dillema. the background story started yesterday, when i washed my hand and tried to reach something over the sinc, the phone dropped from my jacket pocket to the sinc, drowning... :crying:
i took it within a second, of course completely wet.
i opened it completely, seperating the board, battery, speaker...taking everything out.
to be honest the main damage was the speaker. the entire board seem to be dry and the water sticker remained untouched.
after some rice-treatment and patient i turned it on.
the home button is non-responsive..only after some clicks it works.
the power button is another issue, where if i press it it thinks its a long press and a short time after (could be minutes) it reboots.
if i dont touch the power key it wont shut down is it has to be it.
i kinda hate the idea to change phone because i actually like it.
i dont see any other option at the moment (wouldnt want to go to larger screen size)
so i have a damaged speaker, home & power button.
the speaker is replaceable, thats for sure. after all, i could disassemble it completely.
what about the other keys? is it a possible operation? if i need to solder things that wouldnt be the case for me...i dont have proper equipment.
i saw the spare parts for couple of bucks, im just not sure whats possible and what not.
i wouldnt go to a lab because that will cost alot, and im not sure if it worth it.
One morning I woke up and the bottom half of my Samsung galaxy avant (SM-G386T) had a grid of white lines going across it. First time I restarted my phone it went away.
But they keep coming back and now it's more permanent, Sometimes it goes away briefly but they come back. I tried factory resetting. That worked the first time for a few hours but then it came back. and I tried it again and 2nd time there white lines where there during the factory reset.
The lines even show when I turn the phone off and charge the phone. So I believe this means it is w hardware issue
I tried taking the back planel of the phone off. I disconnected and reconnected the lcd connector latch on the left side. But the problem still persists. I haven't pulled up the screen with a suction cup. So Idk if there is a cable that could be loose on the front end or not. But Idk want to go buy suctions cup if I dont need to you.
Should note that I do have a good sturdy rubber case on my phone. but it has hit the floor a few good times.
One other thing that seems to aggravate or sometimes even make the lines go away is putting my phone to sleep and waking it up repeatedly or adjusting my brightness to max.
What do you guys think? is this fixable or do I need to replace the lcd screen.
man its simple
just press the wires of display which are providing it power & ur problem will be gone.
Its due to lack of sufficient current to display!!

What wires are you speaking of exactly. cause like I said I have taken the back off and disconnected and reconnected the LCD flex cable but nothing changed. Are there wires behind the LCD I need to get to? which means I need to removed the screen with a suction cup?
Hi.
My z4 lte has recently started shutting down without warning after displaying the flat battery icon. This happens even if the battery has over 80% charge. The tablet reboots normally if left for a few minutes and on restart will show the same battery level as before the shut down. This is happening more and more frequently.
Any ideas or suggestions?
Thanks.

This is definitely a defect battery. Have the same problem on my tablet Z4 and before already twice on Xperia Z1compact. The phone battery was replaced the second time now. With new battery no problems anymore. (seems to last arround 2 year, then it starts again. Looks like poor battery management by Sony )
Only solution: replace battery!
Sadly the only way is by disassembling the display:
https://de.ifixit.com/Anleitung/Sony+Xperia+Z4+Tablet+Repairability+Assessment/79131
Did anyone managed this successfully without breaking the screen? I replaced a broken screen on my Tablet Z and its true, they are really delicate and new screen is ~250 Euro! (Battery ~50 Euro incl. glue).
(By the way: the Tablet Z battery is still fine, and even if, it would be accessible through back cover. Was really the best tablet by Sony. @Sony: WHERE IS THE SUCCESSOR of TABLET Z4??? How about skipping at least once this useless "every 6 month a worse phone" cylce (XZ2: :crying: :silly: ) and develop instead a new tablet!? )

Since my battery became almost unusable, I took the risk to replace battery myself.
And it was successfull!
Here some hints:
First of all: Make sure you have good tools, mainly:
Only use a very thin and a bit flexible opening tool (I used iPlastix tool, the plastic version)
Use a good heatgun with small opening adapter (< 1cm). Make sure the heatgun can be set to low temperatures, I strongly suggest one that can be set to exact values (In my case "Steinel HL 2020E", can be configured from 80 degree upwards in 10 degree steps)
Build yourself some kind of stand for your heatgun that you can heat the display while having both hands free (I used a small camera tripod and tape)
If you do not have ordered the new adhesive yet, use a internet photo of it to see where the adhesive is located and how deep it reaches. (the edge where adhesive does not reaches edge is headphone jack). Choose a spot with thin adhesive (not an edge) to start.
Heat up this spot (in my case: heatgun on 90 degree celsius, 5 cm distance from outlet to surface) and while still heating, carefully insert opening tool. Do not use force, heat longer if needed. Than slowly move around the tab by heating and dragging your tool. (here the mentioned stand for heatgun helps a lot). After you opened some way, insert a thin piece of platic to prevent adhesive from reattaching.
Again: NO FORCE. When old adhesive is warm enough, you can easily "cut" it with your tool. If you still feel resistance, you need to heat more. (on spots with larger adhesive areas I switched to 100 degree). When you are around, the display should be able to lift, if not, heat again remaining spots and use opening tool until screen can easily be detached. (never bend/pull) There is not adhesive in middle of display, only at corners as you see on new adhesive.
The opening itself was surprisingly easy. More annoying was to remove the old adhesive remainings. I tried isopropylalkohol, but it did not help much. Most of it was removed with some plastic blade, mooving/scratching/pusching permanently against the end of the adhesive trail. It takes time, but it removes it in 0.1 mm steps (maybe someone has a better idea).
Make sure that you work on good mat/base that you can put force without bending screen. I had some sticky but flat remainings on display surface, but this should not be problem.
Removing battery adhesive: use colored edge of pull tab ONLY to grab it. As soon as the white part gets visible drag always on the part that is just coming out behind battery. The first tab teared for me because I did it wrong and it was difficult to remove the remaining. The second tab could be removed completely with ease. (How to detach the cabling, see the youtube teardown videos)
At this step I suggest to replace the main camera lense if the lense coating is broken (as usually on Sony ). Do not remove lense from inside, only the round part gets replaced. Heat up lense and push from inside outwards! (see attached photo)
Replace pull tabs and battery, reconnect cable and TEST tablet before attaching new adhesive! (you may use sony test menu by calling *#*#7378423#*#* in phone app)
Another tricky part is to apply the new adhesive. You have only one chance, as soon as the adhessive touches a surface it sticks, if you try to detach it again it will stretch and stay stretched, so better don't try. Seems the adhesive has to be applied to display first, so detach cable of display, test carefully how to hold and handle before removing plastic covers of adhesive and then: good luck... (Result was "almost" ok in my case. If result is tolerate able, keep it that way. Trying to change again will just worsen the result. Cut parts sticking out display edges)
Reconnect remaining display cable, test functionality again and glue the other side.
Congratulations, you got 2-3 years more of tablet lifetime. Lets hope the guys at Sony get it done to bring a successor until then...
I succeded open my tablet and replace battery.
Now it does not power up.
The red led is lighten up, blinking 4 times, ligten up again and the went off. Repeating again and again after some while.........
I cannot get in touch with the tablet again. I cannot see anything broken or destroyed by open it.
Is the led an error code?
Is there any reset button hidden somewhere?
Sorry to hear ?
Did you tried hard reset? (Press Volume up + Power for more than five seconds)
What happens if you boot to FastBoot, does USB connection shows up on computer at least?
Is device charging?
Is screen backlight starting? (Try in dark room, you should see at least a little lightning if backlight switches on)
