Hi All...my Display gets looser and looser. (excuse me for my bad english)
Now I still have my old universal, on which the display was broken. Now I want te replace the display of my old universal with my new (1 year old) universal. I got the service manual (pdf) but when reading it I must say that it looks pretty difficult to replace the screen...
so my question if anyone had experience replacing the screen?
Regards
Arjan
Hello Arjan,
I've had my Exec in pieces quite a few times trying to fix a faulty touch screen issue.
It is quite easy to take apart and remove the screen. There should be no more than four screws to remove and the case just unclips.
The screen itself is easily removed once the case is apart. There are just three small ribbon connectors to remove. Your new screen will just slot in and you can put the connectors back on.
Clip the case back together and put the screws back in.
It shouldn't take more than 15 minutes to do it carefully. After I'd done it once it took me no more than five minutes.
Good Luck.
Thanx for the reply....
will give it a try
Hi Lakota
I replaced the screen by a new one (lcd + touchscreen) bougt on ebay but the touchscreen didn't work. After cheked all the connections I sent it back to the seller and got a new one, but the problem remains the same. Do you have any idea of what could be the problem and how to fix it?
its the csble running down from screen to jasjar. when sreen get twisted wrong way it breaks the cable inside jasjar. send to pocketpctechs.com for excellent service bro. they will even call u if there are any other issues with your device so when you receive all will be working bro.
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
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
Here is the Samsung Galaxy S3 (GT-I9300) Service Manual.
Please take a moment to read the notes and issues about this manual in this post.
For some reason Google didn't pick up that post, so I had to re-post here...
Now, if you are brave and happen to have a GT-I9300, you can still help us by posting some
internal pictures, to verify some issues in the manual. If they are good,
some of them will eventually become part of the SGS3 Hack-Pack.
Thanks and Enjoy!
I will be opening up the phone in the next few days due to me managing to damage the sim card holder section(not holding sim card) So at present i have got somthing putting pressure to keep sim card in place. I have a new sim card holder on order so when it arrives i will pull phone apart and take some pictures.
If you have any advice for me before attempting this please let me know via pm
Do you have any experience in this kind of electronics? I mean, are you planning to replace and solder the SIM card holder by yourself?
If you have not done this type of soldering before, I do not recommend it.
If you do decide to do it on your own, make sure:
You are working on a clean workspace
You are well grounded and not wearing wool clothes mixed with synthetic materials to avoid any ESD.
Have the right tools for the job.(Temp controlled SMD soldering iron + flux and acid-free lead-free SMD solder etc.)
A very steady hand with good eyes!
As for the pictures, keep the environment as bright as possible, preferably daylight. Try to keep your PCB on a bright or neutral background. (Bright cardboard is usually good.) Inspect your pictures and make sure you can read the text on the smallest chips. (The big ones we already know about, its the smaller ones that are difficult to navigate around.) Make sure the pictures are well focused.
Good Luck!
From looking at the pictures I was hoping I don't have to solder the sim card slot in. It looks easily replaceable as it looks like it's just a connector and not soldered
Replaced the sim holder. My camera wasn't good enough to get focus of the smaller chips however it is very very easy to take phone apart. And I guess Samsung are expecting issues with sim slot so they have fixed it using one screw and connected to board using a pull off connecter.
Just in case anyone else is interested the sim holder/sd holder cost me £20, delivered.

Hi guys,
Here is my contribution to da community, hope so it helps.

On image 20120616_150200.jpg you can see the region jumpers. The images are of a live demo unit - everything works besides the GSM/3G data. Haven't tested to see if the NFC is working.
The real unit has some more antenna connector. The demo one does not have PBA /printed board antenna/ the ANT102 and ANT103 as well as the capacitors and the coils u may seen them market in red cycles (ANT102, ANT103, C102, C191, L103, L102) there is no room on the MOBO for C192 /or at least I can't find its place/.
Thanks.
^^ Here is the link for above! (Thanks!)
Hi again,
I can confirm that the NFC is working on the live demo unites. According to the original S3 user manual the NFC antennas are build into the battery back.
I still can't figure out what is the "W2" antenna connector for. The Live demo unit has no connector soldered to the motherboard and also lacks the small PCB antenna with the white coaxial cable. Some ppl claim that the W2 is for WiFi antenna, but it is not, because I got great WiFi connectivity tho the lack of such PCB antenna. I can only confirm the WiFi working fine, under "G" type of WiFi networks. The openWRT firmware of my current router has known bug and I can't bring up "N" standard in air, to check if the PCB antenna is for "N" type of WiFi networks.
I also did some testing to see if the PCB is for GLONASS or GPS, and it seams that this PCB antenna with the white coaxial cable is not for any of these services. That's why I think it might be for wifi "N" or 3G data/networks. Donno if the 802.11n requires a separate antenna.
^^ Please post a link to a specific image, that clearly show the connector(s) you're talking about.
Hi I have a live demo unit to, so I think I can help about this =).
I can't show you the mainboard back because I' m new user... xD
I don't really know what you mean with NFC (sorry, I'm not really good with english)
But
W1 is a GSM external antenna conection
W2 is a wifi external antenna conection
And the white wired antenna is for wifi to.
After thinking a lot, if you conect an antenna to the GSM antenna conection (external or the internal lacked in Demo unit) you probably can't use phone function.
That function probably was crippled by software or because demo units don´t have imei maybe o.o.
The only thing I need to try is to connect a microsim to the phone
No one has any insights ???

Samsung galaxy S3 i747
i have a Galaxy S3 SGH-i747m that has been water damaged and given to me so i could try and fix it. I can take pretty much any pictures you want, have openned the phone a couple times now to try and clean it up.
My problem is that the works well, it starts up, unlock the screen, plays sound...but the screen is off. Now at first when i was "playing" with it the screen would flicker on and off to show me the battery charging logo when it was plugged in. I've cleaned the phone and all flex connectors with some products. the phone still turns on and works but my screen is off. It detects the touch since i can unlock the screen ( it plays the water sound when i slide my finger on the screen) and speaker works when i boot it up (little booting sounds).
I was thinking there might be a small fuse on board for the screen backlight and that could be blown. I was also thinking my battery might be damaged and is not giving the phone the right voltage to the right connectors or something so i have ordered a new battery on ebay (under 4$) and am waiting for it.
Anyone has an idea to some specific things i should be looking for ? only thing haven't disassemble is the digitizer from the framebecause doing so would surely break the glass. It bums me up a bit since there are some electronics behind the frame that could have been damaged by the water that i couldn't see.

check if you can see anything on the screen, use some extra light, torch for example.
if so - then its more likely that the LEDs in the display panel are damaged, since it flickered, as you said. also could be the driver circuit for backlight. Clean connectors for display panel, use magnifier, or better microscope to check for corrosion. use IPA to clean or scrape off the corrosion.
also - maybe this is not the right place to discuss this.

I don't have he white antenna coaxial cable neigh the PCB antenna board that this cable is connected to but I have WiFi.
Could it be for WiFi N(150Mbps)?
Watter damage, LCD working/not working?

I have identical symptoms with my i9300.
1. Water damaged
2. Dried in a can of rice etc over several days
3. Cleaned under sim card, lots of debris there, looked scorched, I cleaned with alcohol and a brush in an ESD protected environment.
4. Re assembled, the display briefly flashed on, and showed the expected "Battery is low, an d No Sim Card" then powered off.
5. Now after charging the battery and emplacing my sim card, I hear the proper musical tones when the phone boots but the screen doesn't light.
Where you able to get the screen working?
I am going to try a more throughal cleaning and I will try viewing the LCD under a more power full light.
I too worry that just getting the LCD screen replaced might not work; the screen may be fine but the mother board LCD power supply might be at fault...
I will keep you posted and keep an eye on this forum to find out how to fix this.
This thread has served its main purpose.
OT discussions are prevalent.

Hello,
Had my N4 for about 2 years now, right from the start. It fell on the floor a few times (no bumper or case) so I guess that's the root cause of the issue.
I have a horizontal thick line that is untouchable.
Attaching a screenshot of me just drawing straight lines top to bottom and as you can see no lines are drawn in that area.
A repair shop took it apart, cleaned some parts and put it back together again, said it's not a dust thing but more likely either a screen or touch sensor replacement.
I was thinking about Ebayying it because it will be a whole log cheaper.
Is this it - ebay dot com /bhp/nexus-4-screen
And what if it's a 'sensor' chip issue? is that something else?
Also, I'm a fairly technical guy so I won't have any issues with assembling it. (I hope).

If you had asked before taking it into the repair shop , i could have saved you a couple of bucks
Anyway , buy it from gadgetfix (ebay) , if you're gonna buy it from somebody. Else , you might have gps signal/proximity sensor/notification light issues. Some make a frame from scratch , which is supposed to be a magnesium alloy , they probably don't get the mixture right , signal degrades , gps is affected the most. Some have deeper proximity sensor sockets , which creates a gap and the sensor registers that gap as an object , so it'll turn off during calls and will not turn back on until the call ends. Plus you won't be able to use apps like Gravity Screen. Some assemblies don't have a notification light diffuser , which is bad because nexus 4 has 2 leds that light up as different colors to achieve off-colors such as purple. The one on the left will give out blue the other one red , when it goes through the diffuser , it becomes purple. If you don't have that , you're just gonna see those 2 colors and it will blind your eyes but you will be able to see the phone's internals if you think that's cool
Disassembling it is pretty easy , you won'T have problems. Buy the assembly with frame not just the glass and the lcd. If you can't manage it somehow (unlikely) , just pm me , i'll guide you on skype or something.
Cheers!
