Replacement of touchscreen!

Does anybody have a manual for the replacement of a touch screen, and an adress to buy touch-screen for MDA Compact !

try ebay...i saw some touchscreens for $20 AUD, which is cheap...
Though dont know how to replace it, looks HARD.
whitemoo.

Thanks! I hope someone has a online manual...

Wel if its anything like the xda2 then replacing the screen is very easy as its just a few screws and a ribbon cable. I had a broken screen xdII and took it apart to see how hard it was to reinstall myself, it was very easy cos like i said it was a few screws and a ribbon cable.

There's a guide with pics in pdf format in this forum, just search for it.

Its very simple as long as you are patient and you don't force anything while trying to open up the phone.
I have worked on couple of Imate Jams and wizards with out a manual without breaking anything.
I have seen the manual on the wiki I believe....
BTW I would suggest using one of those ebay cellphone repair kits that come with the plastic tool to open the phone that helps alot.

wanted htc wizard main board

I broke the screen on mda and purchased a replacement but I think i fried my main board during the installation of the lcd. Is anyone selling a mainboard for the wizard or know where I can find a mainboard? I have checked on ebay and have found broken phones with bad usb connectors or headphone jacks. I don't need that. If anyone is selling a mainboard for the wizard as well as the housing, as long as its in good condition, please let me know. Thanks --> Mistawright

Are you sure it's dead??

I've just received a new screen for mine from HK. When I first put it in all I could get was a white screen, nothing else.
After ages of stripping down etc I found that it was the screen connector causing the grief - tape it down with some electrical tape and away it went.
Got versed in the art of connecting the screen to the main board and holding the battery in place at each stage of the re-construction to ensure it was still working.
I dropped mine and had vertical lines on the right side of the screen. Now, with the new screen in, initially it was fine but has just started wavering a little on the right side, so I may have had more than just a screen issue. Still as long as it lasts until my Kaiser arrives from T-Mo I'll be happy.

So are you selling a mainboard or not? If you are not what was the point of your post?

The point was in the subject of the reply: ARE YOU SURE IT'S DEAD?
I offered help based on my experience changing the screen and questioning wether your mainboard was really dead or not.
But if you don't anybody offering advice and only want to buy another mainboard without really checking if yours is dead or not then I'll shut up.

lets start from the beginning.
1) I broke the screen.
2) the phone would power on but cracked screen.
3) I bought a replacement
4) after taking the phone apartment and replacing screen phone does not power on
5) Amber light does not come on on phone when connected to charger.
Instead of suggestions like the topic of the thread says I'm looking to purchase a working mainboard or a phone with a cracked screen that works at a decent price.

Hi,
Did you follow any replacement doc to do the job? Or you just started alone? I asked you cause I got a LCD for my friend and together we replaced it without any problems. Everything is working fine! Remember that exist many pitty hardware parts during the process you should care about it. If you missed or have broken one of them, you'll probably fried the main board or similar component!

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.

Looking for a broken Universal

Anybody have a broken HTC uni?? I need the part that connects the mainboard to the screen, my son got a hold of mine XDA EXEC version and kept turning the screen around and around.
Anyways I took it all apart and found the faulty part so I'm looking for one the possibly got wet, broken screen, broken ports, broken keyboard etc...
Or possibly if anyone knows of a place where I can find the parts...

Welcome to forums
Ask a Mod to move your thread to marketplace so you´ll get better chances
Good luck,

I've got one if you wanna buy my. Got one where the screen is blank and the other where my usb port is gone.

You can just get the part off eBay, it's something like $25-$30.

I had a similar need: I had to buy a broken screen Universal, to take the motherboard out and fix my device (problems with bootloader...)
I got a screen damaged Uni from ebay with 16 pounds, and when I got it I saw the screen ok, and only had to push the connector inside a little harder and all was good. So I got a fully functional Universal device for 16GBP. My advice is you try Ebay.
