screen just shows lines

anyone know how/where to get an xda mini II repaired? i'm in italy, but i can careless where it has to go. I'm at the point where i would rather just sell the device for it's workable parts (if there are any)...Today the screen has done a myraid of interesting things...anywhere from blank to thousands of vertical lines....ugh...
ohh yeah...warranty is void....or is time to just move on?

ok...no answers so i thought i would add some images ...anyone seen this before?

Mate i had a similar **** up a while back ...I did a HR and it worked fine..for me it was caused by a Overclocking software [Dnt want to Name it ]
If this dnt work try the Batt out and back in trick
Call ur Local service Center...

mine looks exactly teh same! but it happened after i tried to replace my housing, i screwed up the little gold prongs where the ribbon connector from the lcd plugs in...****! any ideas on how to fix? im the us so service center isnt really an option, and id ont want to send it off.

hi i had the same problem with my magicians, after i changed the housing. i found the problem with my device was that i had not plugged the screen back in properly. all i did was to ensure that it was pushed in properly before i clipped it back in

Menappi -
I had the exact same issue. I reopened the casing WITHOUT disconnecting any cables. I flipped the screen's ribbon black lock up, while maintaining pressure on the ribbon so that it does not pop out. When the black lock lifted, the preasure of my finger moved the ribbon further in . I pushed the black lock down, reassembled the device and ... PRESTO!! the screen works perfectly... and chumps on the bard advised to buy a new screen!!
Good luck

Hi All,
seems, you have problem somewhere in display connector. However, sometimes I see similar picture on physically broken displays, let's imagine, you were careful ad didn't use a hammer during housing replacement.
There are two possibilities: at first - try to remove and re-insert display cable (I hope, you know. how brown lock works). If there is no success - try again. At second - some wire on flat cable may be damaged. Sometimes, good technician with soldering iron can fix it, sometimes not. And if you used force, removing cable, board connector may be damaged too. However, only the experienced man can find it easily.
So, try to carefuly re-insert display cable. Try several times. If you are unsuccessful, you, for sure, need an experienced technician to fix your device.
I hope, you are not enough mad to send device for repair to Russia

digitizer (touch screen) replacement

Hi guys this is my first post (so please be gentle )
I had a hermes with WM 6 working great until my toddler got his hands on it and now the touchscreen doesnt work (looks like its caused by large dent in the centre of the screen), I've had a look around and found the problem to be with the digitizer itself. I was thinking of replacing it myself with this I found on ebay
http://cgi.ebay.co.uk/ws/eBayISAPI....m=260193961530&ssPageName=STRK:MEWA:IT&ih=016
Just wondering if anyone had purchased one of these and had any feedback as to if they actually work and any tips on fitting it

I would give it a shot as its not to expencive and could save your phone.
I just like the way they bundle in a kit to take the phone apart but ask you to make sure what colour the connectors are on the inside of the phone before purchaseing :-D

thanks for your reply, i may just go ahead and give it a go then, I could post the pictures or a guide if its any use to anyone? Other than that wish me luck (i may need it)

The touchscreen on my Cingular 8525 stopped working today, so I'm faced with a similar dillema. I saw the digitizers for 16-20 dollars online, but I've heard it's safer to just replace the entire screen since you have to seperate the screen from the digitizer with an exacto blade. Either that or I'll have to send it to pocketpctechs and be without a phone for 5 days. Thankfully I can still navigate the phone with the jogwheel + dpad.
I found this video showing how to disassemble your 8525 if you're interested.

well just to follow up, the replacement touchpad arrived yesterday it was well packaged and even included a CD containing instructions on how to replace the digitizer itself. I removed the old digitizer (using the edge of a tape measure as it was the only thing i had thin enough) and installed the new one and I have to say im well impressed, all works as it should
A bit of advice though, try and use a soldering iron that is less than 15W as I nearly burned through the contacts but other than that i have my baby back yey

HELP! T-Mobile MDA screen going loco

Hi, peeps. Would like to ask for your assistance in troubleshooting my old T-Mobile MDA - the one that is also the Xda mini S.
The unit in question is 2nd hand although it was still in good shape when I got it. Used it for over a year already and has seen much use. Once, the insides got wet and I had to dry it out but it was okay after that. Although the keyboard wasn't showing any backlight until I figured out that a blowdryer would help remedy that situation (after careful dismantling).
Recently, the screen when you slide open the keyboard either comes up blank (whole screen is just white) or is discolored and a bit disaligned (the top part is either missing or is at the bottom of the screen). It happens too on the normal layout at times.
I upgraded the firmware with the most recent one I downloaded here last year. No problems experienced though with regards to the OS and not sure if the recent problem can be attributed to it.
Any ideas and suggestions?

I got the same problem on with the screen my Cingular 8125. When I slide the keyboard open, the exact same thing happens to my screen. Sometimes It only used to happen maybe once every 10th time, but as of last, it is happening all the time.
I spoke to someone at a repair store in Toronto and the guys said it will cost close to $100 to replace some wiring in the back. It didn't seem worth it for me so I got another phone instead, but I would love to keep using this phone if this could be replaced.

Hey guys. If you are comfortable, I would suggest dismantling the phone and taking a look at the ribbon connector between the board and the screen. My guess is that it is loose, or damaged. Reseat the ribbon and try again. Otherwise I would see if replacing the screen helped. Certainly much cheaper than a new phone...

Reseating
first of all check out the socket (on board) where the screen coaxial cord is plugged in , r all the connector pins alligned or are any bent / pulled back ?
in that case reset pins location using a tiny neidle or pin, also use a double faced adheisive tape on the back of the screen connector to rest it tight to keyboard (original setup only they use glue).
second check out if the screen does that if was flipped using software , if it was a hardware case and upper solution wouldnt help then check to see if the sliding mechanism (two plastic identical bars screwed by two screws each to the top and the buttom of the screen) are aligned and screwed tigh to the screen.
now the wizard hardware is a survivor but any tampering with it require tight reseating , screwing and later reflashing (even if the software showed unaffected).

Question about:Replacement of LCD and digitizer and a wierd piece

Hello everyone..I recently replace the lcd for my niki htc...I bought the screen from ebay for $35 (plus shipping). Everything works fine but sometimes when i slide the phone the screen is wably or it looks like something is not connected and it moves but when i close it and i restart it again. it's fine or if i let it for awhile like that (so it goes on and off). So my question is...Is it the manufacture that made the screen, or is it something that it hasn't been connected right?
The other question is that my digitizer is broken in the up left corner and im thinking to replace it does any one can tell me how to take of the digitizer. i have found this website :http://www.pdacenter.ru/razborka/razbor_htc_touch_dual/ but it stops at the screen it doesn't tell you about the digitizer.
And the 3rd question is about that little piece it has fallen from somewhere while i dismantling my phone, i took a picture of it so someone can tell me what it is and where it goes.
Thank you very much for looking, and sorry for the noob questions first timer dismantling a phone and i loved IT!!!

You may wana have a look at the service manual, wich can be found here:
http://www.mikechannon.net/page1.html
It says that you can not disassemble it without replacing the speaker!
When you remove the speaker you need a new one. (or at least this is how I understood it
Maybe that part is the door for the MicroSD Card slot?

no i opened the cellphone 6 to 7 times so far. all you have to do is to unscrew the small screw that keeps the speaker in place so you can have more space to work with it.
all you have to do is to take off the digitiser where it gets connected. take the screen off. and raise the little black strip where the digitizer stripwires come out and push out the digitizer. it feels liked it doesn't go out but if you push it carefully it will. they have glue it with some kind of glue that it doesn't come off the digitizer but it stays on the cellphone so you can put in place your new digitizer...
If anybody needs help... pm me or leave a reply in this thread.

speaker rubber perhaps?
I just replaced my digitizer today (bought the handset from ebay - faulty touch screen). The little rubber that covers the speaker fell out in my hand when I was dismantling mine, so maybe thats what it is (looks similair).
Oh a quick question - after replacing my digitizer, my touch screen still doesnt work, even after hard reset - when asking to 'tap screen to set up device' it wont respond to any taps. Any ideas ?

my friend i think you have a bad digitizer, some people on ebay send defective digitizer and especially when they are from china they don't really care about sending a good one.... I had to send mine back 3 times!!!! i just got the last one 3 days ago and it took me at least a month and a half to send me a working one...If you pay with paypal...Tell the ebay user to send you a good one...Do not!! Do not!! send feedback until you got a good digitizer....Mostly it has to do with the connectors i guess where the digitizer connects.... Tell them that you need a new one and you can't wait for very long...tell them this is a customers cellphone and you need to have it fixed as soon as possible.. If they don't want to exchange for a new one dispute the payment!!! Don't wait too long...Do it Asap... As i told you there lots of defective digitizers....I had reset mine also but nothing happens i believe this is mostly hardware problem...If you have any questions about how to dismantle ask me... I have open my cellphone over 10 times cause of the digitizer

Thanks Nikos, Im fine with opening these devices they are easy enough to work with.
I purchased a digitizer for a Polaris not long ago and it worked perfect. Im gonna take the Nike apart tonight again and adjust/fiddle with the connections to make sure - I dont want to wait another 2 weeks for a replacement digitizer and pay for postage lol.
But i guess if it doesnt work tonight I will have to 'grin and bear it' and send it back

Just built in a replacement digitizer. Everything works quite well, some inaccuracies in the lower parts of the touch screen, but it works.
I managed to leave over a screw. And a barely visible stain between the Digitizer and the LCD.
But at least it is working again as a replacement phone and for testing various stuff...
btw, now knowing the phone from inside, that part could be the "door" between the SIM slot and battery. or the rubber part that directs sound to the microphone on the bottom front PCB.
cheers

X1 Ribbon cable - what happens and a fix I came up with!

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.
