After the replacement my problem is still there? Can somebody of you tell me what's wrong?
Kind regards!

Connector/PCB damage, maybe?

I just replaced mine and got the same results... before this the digitizer was broken but the display was still perfect. All ribbons seem to be connected properly, no visible damage...

get a different lcd. Be very careful not to put any pressure on the screen when putting it together. I don't even tape mine in. I destroyed the lcd once with just light pressure putting the back of the phone on and the digitizer was still good. Luckily I had accidently ordered 2 screens so my second one I was more careful.

LG G2 broken after replacing screen
I just had the same problem, I don't think it's an issue with the screens, I think it's an issue with the video card or something.. I had bad digitizer, I first replaced just the digitizer as my LCD was fine, new digitizer had dead spot and I accidentally poked a hole in LCD. Had the black oooozz all over, but still worked and could see what you're doing, do I bought a assembled LCD, digitizer, and glass.. Replaced it and got a bunch of colored dots, put old screen back on, and it's now showing bunch of dots. I did notice I'm missing a pin on the phone's connector for LCD, not sure if it broke out when disconnecting old LCD or if it's supposed to be missing.
Did anyone get theirs fixed with me LCD or is the problem else where?
I noticed the internals were very similar to nexus 5, do they use same LCD or she connector, anything compatible there? I bent, wiggled, cracked old LCD and it still worked besides the black ooz, until I connected new assembly, so I'm thinking these LCD's are pretty durable and pressure on them didn't cause this issue.
Edit... Just looked up photo of connector, all pins are there.. Mine is missing 5th pin in from the right.. On bottom row..
Another edit...
I found the missing pin on my table, tiny thing, inserted it to connector, tossed a tad of silver solder on it,reconnected LCD ,works flawless!

Same issue
I have the same problem ( Color dots), so you solved by reconnecting all screen connectors? I really don't know what to do.

hi
you bought an original piece? purchased online or at any physical store? apparently your problem is in the connectors, however we can classify your new screen as a low quality product.

Same problem

Maybe the problem is with the motherboard,
I'd suggest go to a repair shop, so they can test your motherboard on a different screen (for free i hope), to see if the problem is: Flex? Screen? or motherboard?

Did anyone figure this out cause I'm getting the same thing on mine with two new screens and no loose connectors?

Just replace my screen, purchased a part on ebay, the phone boots ok, can see the image and the touch is working but I got a extrange problem when you hit the power button to lock the screen and try to get up back again he screen turns one and after a second shows a white screen then a dimming until it turn off, the only way to see the image again is making a hard turn off and turn it back again, my phone is a sprint model ls980, any idea what happen??? Thanks

I have the same problem with mine I pretty much have to leave the screen on or restart whenever I want to use it
Sent from my LG-D800 using Tapatalk

I have a probleme with the replacement screen, we replace not just a lcd and the digitizer, part of lcd with frame. I buyed this from England. After the replace i can't turn on the screen many times, but the background lighting working and the touch/digitizer too. I press the power button once turned on, not once. We disassemle much more and testing the power button, we found nothing, we connect once more the LCD connector on the PCB, nothing.
Have you idea, what can I do more?

The problem is with the software so the rom not support the screen from china I found only one what can support on my device its the 80220b stock what is working, how ever I didn't find any other solution jet. If anyone has an idea to solve I vill be happy

LCD issues as well as sound
There are two different screens that I have found. I have the ls980 and had this problem with the LCD after three screens brand new. There are two types of connectors for the LCD cable I can post pictures tomorrow. A lot of manufacture or Leo's on a.azon think a g2 screen is a g2 screen but it's not. Ls980 d800 as far as I know have the same connector so make sure the screen your getting is for your phone that will fix any LCD issues as well as sound issues.

BUY/SELL a broken Wizard! Protect our dying breed.

do you have a broken wizard you'd like to sell? simply put it under www.ebay.com and signal the broken wizard offer (THE LINK!) under this thread - specifying the type of defect.
There is a number of OTHER broken wizards (like mine!) that could be repaired by recovering parts from others. And very often we could repair more than one - so after you've repaired yours you could try to resell the remaining pieces.
So, anybody having a broken wizard: follow this thread and we will ALL save money!
As you know, the service manual is very detailed and allows easy replacement of many parts: screens, keyboards, mainboards, stylus holders...batteries!
anyway, we are not anymore under warranty....right?
Comments also welcome, since keep the thread high in the list...
Anything YOU NEED?
Hi,
all those in need of parts could also post here...i desperately need one LCD PCB - since the connector on the flat cable between the LCD and the PCB went bad and my display doesn't work anymore/ after months of shaky performances...THX
anybody got a screen around?need the lcd+digitizer. im not sure yet whether its a gold or black connection, will check later on, but just wondering if anyone has an lcd around..
where could i get the service manual?
anyone know where I can find a switch? Yes, a switch not the button. Long story
Hi,
I have for sale the LCD and touch screen. However, it's more complicated.
My touch screen was cracked but the LCD was good so I bought a new touch screen and tried to fixed it but I was not able to connect touch screen to the LCD (solder the tape?). So I quit and bought a new LCD with the touch screnn. So now I have an used LCD and a brand new touch screen for sale. If you are good in fixing things, I'm sure you will have fun
Let me know if you need some more information or pictures.
Peace,
Tom

My son's Wizard/Cingular 8125 Died
I'll be listing my son's Cingular 8125 later on today on Ebay. It appears the motherboard went "belly up" on it. . . just 3 weeks out of warranty. At least -- from reading some other threads on the forums about the same type problems, that's what I'm surmising happened to it. It wasn't dropped, kicked, sat on, run over, etc., etc. -- it just shut down while he was on the Internet, never to be revived again. I tried switching out his battery with my fully-charged battery to rule that out and tried a few other ideas I found on the forums -- NADA.
No blinking LED when plugged into the wall charger and the PC gives me an error message that the "USB Device has malfunctioned" when plugging it up to the USB sync cable. He had been running the WM6 Underground Edition ROM for a little over 2 months without any problems. It's also one of the original G3 chip phones.
Thought I'd post on here before listing it to see if anyone is interested. PM me if you are.
(MODS -- if this isn't allowed, please remove the post, and I'm sorry)

What do you mean? Did the actual button break the one inside soldered to the board or just the case button that is used to press on the real button?
I broke the actual button trying to put the case back on and I got an old board I am desoldering the buttons from. If this is the case then I could probably send you one.

My wizard nearly fully survived a good old swim in a lake. The only thing that's broke right now is my touchscreen. Does anyone have a spare one they could sell me? It's a touchscreen digitizer with serial LTP280QV-E01
Many thanks

Tmobile wing screen replacement

UPDATE
I did it
I bought a digitizer from ebay 17$ shipped versus 50$ for a lcd combo.
Arrived in a week from hogkong, wrapped in toilet paper (unused) with a screwdriver (wrong size) and a plastic opening tool (kinda useful).
I took apart the phone using the instructions, you can find them online if you google for them.
I removed the LCD-digitizer combo. Now the tricky part:
removing the digitizer is hard, it is very well glued/taped to the screen. Mine was broke so after I removed the plastic sheet(the actual digitizer) I had to remove piece by piece all the glass. It was a little war on my desk that resulted in a little scratch on my screen but in the end I did it.
removing the connection tape is not hard, the connector is just attached.
I set the new digitizer in place, insert the ribbon through that hole (actually I had to remove the metal back from the screen to do that).
I taped the new ribbon. And it didn't work. I read somewhere that you have to solder it back but I don't have such a device and buying one defeated the purpose of spending all this time taking that screen apart.
So I carefully clean the connector, set it in place and taped it again. Didn't work again. But I noticed that if I putt some pressure on it the it works.
so I put a bunch of tape there and when I put the phone back together it worked.
Time: about 4 hours of work. But it is my first time I took a phone apart , and I kept loosing screws and all sorts of adventures.
It's not really worth it, more likely I broke something else, i had a hard time reconnecting the keyboard, I actually had to cut a pice from the keyboard ribbon because of the faulty contacts but IT was a fun project. I was debating between a new phone and fixing this, and i decided that if I screw it completely it doesn't matter, and i guess I had some good luck. If you guys have any questions, I know i should have take pictures, but I forgot, you can email me at [email protected].
Thank you for all the help I got on this site.
I broke my screen (Tmobile Wing) but I guess I cracked only the touch screen, not the LCD. The phone works, the LCd works, only the screen does not responde to any touching.
I found LCD screen replacements (~50$ shipped) but I also found the touch screen only replacements (~20$ shipped). Does anybody know if Only the touch part of the screen can be replaced? I never took my phone apart. Is the screen combo made from two layers that can be separated?
Thank you for your help.

wow good to know, unfortunatley i had purchased another device before even checking up on these things, i was still new to this site and my Wing...oh well
I took my broken lcd apart to see if I could get some info for you. It looks damn near impossible to detach and re-attach the the ribbon cable for the digitizer. Since yours is broken, you might as well take it apart and see for yourself before buying just the digitizer. Good luck

Hi: Just now read your post..Am I understanding that I don't need to buy the "LCD" screen for $45.00 and only need the touch screen that sells for $17.00? If so, then the cracked part underneath the plastic on my Wing is fixable? My phone still rings and is answerable but I cannot call out using the screen. The backlight etc. is still working and I just bought this so I am looking for a cheaper repair. Thankx
LCD vs. TOUCH SCREEN T-Mobile Wing
I think I can replace just the touch screen if the glass underneath the top plastic is cracked..(In a hurry to visit Halloween Horror Nights @ Universal Studios and ran over it) The phone still receives calls but the screen is white and when touched turns the cracks black, the backlight is still active, the qwerty is fine etc...So.................do I need the LCD or just the Touch Screen?

digitizer replacement
hello. I original got my wing with a broken LCD, I replaced it with no problems and it worked fine. I have since broken the glass on the digitizer. The digitizer glass from my old LCD was not broken, it is now that I tried to remove it from the broken LCD.
Also, there are two different types of digitizers. one the ribbon cable is on the right, the other is on the left. The LCD[with digitizer] I purchased had the ribbon cable for the digitizer on the opposite side. It worked great until I broke it.
So, my question is: If I purchase a digitizer from eBay, does it come with the glass or is it just the plastic digitizer itself?
Thank you in advance,

The replacement digitizer off ebay works ONLY when I push the ribbon hard against the lcd screen ribbon where it attaches. What is the way to stick it that it connects and conducts power as it suppose to? I tried the taping method without success as noted by the 1st post.
Help please

They come with the glass, just be sure to get the GSM version, not the CDMA. I know this is late, but might help someone else if you've already done so.

Solder it... but you've pointed out that you can't or won't do this already. I don't know of any electrically conductive glues (especially trying to glue the ribbon cable in place without shorting itself out)

Please Help! Black screen but LCD has backlight!

Well guys this is what happened:
1. My wife got mad with me and broke my lovely trinity. In fact only touch screen was broken, lcd still works.
2. So I bought a new one on ebay (lcd+touch), so much more cheaper!
3. I replaced the broken one for the new one and everything was fine, I got my trinity back
4. Anyway I had to disassamble it all again because lcd was not placed conveniently, I've done it several times until I got it perfect but when I power-on there was no image on LCD, just a black screen with backlight.
5. I thought it could be a damage in flex cable, but older lcd leads me to the same result.
Any idea?
hello friend how the things going!!??!
Can't find a reason for it! Broken flex or chipset damage? I'm not in the mood to buy a new one to check it!...
hi, it's has appening the same thing to me!!! but i solve it!!!! how? my problem was in the connection of the LCT to the motherboard! I just have put a small paper in it between the cover to make some pressure on it and then the LCD work perfectly!

Boy I just bought a new LCD on ebay thinking i'd get my problem solved!
So we'll have to wait someone help us...
Great! I got my trinity working now with my brand new lcd, but it's kinda unstable i wonder if could be keypad flex cable that is broken as i read somewhere that a broken cable could cause other issues...
NOW SOLVED: I unpluged keypad flex and removed the whole board now it works perfectly (no keypad of course, but i'll buy a new one )
happy for you!!!!
hope you can release a new PTG rom for trinity!!!!
greetings
Thanx!!!!
Thanks vimafeje!!! you are great!!!! i thought my problem was software!!! i tried all kind of stuff,change roms, radios, format with mtty, unbrick..and always got that black screen!!! almost tried everything!!and i luckily found this thread... your solution was mine!!!
before reading your thread i used to make some pressure on the down right side of the battery...and it was working a couple of minutes because when pressing on battery i was pressing under screen !!!
anyway......i'll try to disassemble it to fix it.....
i think my problem came from one of my trinity's fall !!!
take good care!!

hello,
its look like you are having a connection problem with the flat cable to connect the screen to the motherboard. making some pressure in the side of the trinity, like in the picture posted some post ago qill prove that.
so, have you try to dismantle them?
try it, and make shure the flat cable is in place, try to turn on the phone while he is dismantle, and if the screen is not working, try to touch this flat cable.
i solve mine by luck, i have dismantle mine more than 50 times!!!!! but now, it's working wonderfull!!!!
good luck!!!
try it,
The problem is the flex cable connection of the display or keypad to the motherboard.
Check if the display flexcable is well aligned and properly inserted into the motherboard slot.
Place a piece of paper or other soft material on the two connectors (display/ keypad) to improve the pressure from the back cover in these components.

here to put the paper:

P9000 Disassembly (I broke it)

So I dropped my phone and broke the front glass. LCD works but not touch-screen so pretty much useless. I decided to take it apart first to see how hard it would be to replace the screen as I could see screens can be bought from AliExpress for about 65 USD or 99 USD from elephone.hk.
Took some pictures along the way as I couldn't find any images of the internals of this phone online so this might help someone trying to replace their screen or just thinking about it.
1) Back cover - this comes off rather easily once you get something between the edge and start nudging the clips to open. Notice that the whole back cover is glued a bit to the battery so even after getting all the edges open I still had to use some force to remove it from the battery. PS: The side-buttons are attached to the cover also so try not to hurt those while removing the back.

}
2) Next I removed the bottom half cover to see if I could access the screen cables from there. Notice that the black ribbon that goes to the screen is the home button LED light and cannot be removed without unsoldering it!
3) I took off the top cover and unhooked the battery.
4) The battery - It's glued to the metal frame using 2 strips of glue and it took me 10 minutes to get it out safely without damaging it (it's soft so you can probably easily make it explode in your hands).
5) Took me some thinking but I removed the whole main board. The bottom side is glued and I had to break some black "paper" to get it out.
6) Screen - After getting the main board out I had enough room to force the screen out. Notice that the screen is glued from the top and bottom but sides are not glued. Some sensor cable from the front panel is glued to the camera's LED lights. The speaker was a bit hard to take out and I managed to break one of the soldered cables for that :S The bottom of the screen was glued on extremely hard.
Some notes: You definitely need to remove the battery as the screen cable runs underneath it. I'm not certain you need to remove the main board as it seemed you might be able to replace the front screen without taking that off. There's a lot of glued stuff in there so you better have good tools to pull things apart without breaking it.
So finally after having taken it apart enough and asserting a few things I decided that replacing the whole screen and re-building it will take too much time. I just saw a deal for $199 with wireless charger included. So having a choice of $65 new screen + 4 weeks of waiting and then spending 2 hours trying to replace it or buying a new one for $199 and getting a wireless charger + extra USB-C cable - I just ordered a new one. Plus I get to keep the old phone parts around for spares in case any of the side-buttons or front-speaker etc break
Just a note - my phone was in the official flip-cover when falling and got hit into the bottom right front corner and the cracks went all over the screen. I'm rather certain now that the phone's front glass panel is rather fragile and while having the silicone enclosure would've saved it in my case it's still a bit easy to break.
PS: Just wanted to add that I was actually genuinely impressed by the overall quality of the phone and Elephone in general for providing decent updates and support and assembly quality was good so while the glass panel is fragile I still decided to order a new phone from them!
Hi, I also had to replace the screen, so I tore down the phone before I ordered the new screen to see if I could do it safely. And I did (I didn't have to remove the main board, I just removed the screws and left it loose so I could remove the flat cable from the top. The problem is the screen took a couple of weeks to arrive and now I don't remember where a couple of small metal pieces that looks like contacts go. One is golden and the other is silver, both very small, looks like they fit in something similar to the antenna connector. Do you have any ideas of where are they supposed to go?

I cannot remember exactly either, but I think there were two of them.
One of them was visible on this pic in the top right area, above the cable that goes under the LED lights.
The other one I remember had a similar purpose, but since I packed the parts away already I cannot remember where and it would take too much time to re-piece it together to figure it out.
(Exactly the reason why I decided to go for the new one instead of replacing the screen).

I finally figured it out. Yes, I saw the one in the pic, and the other one goes in the bottom part, on the right, just below the top right screw to hold the plastic bottom part. I finally managed to assemble everything back with the new screen and it works perfectly. Thanks!
i also have to change my display screen hopefully new arrives soon and the change is not to complicated

And last few minutes of this showing how to remove the back cover
Hi,
I'm thinking of taking my back panel off for the purposes of fixing the GPS connections as advised here: http://bbs.elephone.hk/thread-11201-1-3.html#.V9SPfygrKM9
Now the op talks about aligning the springs with the backpanel connectors. Can someone take whichever picture is above and highlight which springs they mean?
i broke my screen on this phone, i have horizontal lines appearing on it, have tried three new screen and all display the same, i think there is a problem with mainboard after it was dropped so i am going to buy a new mainboard, anyone else experience this issue, when i wake it up its fine but after a second the lines come up, im pretty sure the screens are fine but something comes up and makes the lines
I've got this phone. I kept it in a safe place disassembled and at that time it was working, some days ago when reassembling the device, it shows no sign of life whatsoever, nor power up or charging battery; I thought the battery was completely dead, bought a brand new one but same situation... Do you think is possible that some kind of oxydation prevents the phone charging and power up? If connected to PC via usb cable, it shows Mediatek Preloader, so I think the phone is not dead.... Thank you all for answering, regards.

P580 Power Issues?

Hey all, I recently bought a P580 when I was out in the States with work (I'm back in the UK now). Whilst I was out there it was working fine and when I came back it was working fine when I originally tried it out - I didn't want to use it much as it was supposed to be a gift but wanted to make sure it was all set up and stuff. Second time I tried it, it won't power on. I've tried multiple USB cables, multiple wall plugs and tried charging it on my PC. Nothing seems to get it to power on.
Everytime I connect and disconnect it to my PC I get the audible tone that says a device was connected but that's it. Samsung's Smart switch doesn't recognise it either. Talking to their support, I've tried holding Power + Volume down + home button but that doesn't seem to do anything other than disconnect it from the PC and holding the Power button for more than a minute doesn't seem to do anything either.
I hadn't rooted the device, in fact I'd barely done anything other than install a couple of apps like Facebook, Snapchat and Youtube. Does anyone know what's going on with the device and is there anything I can do? I'd definitely prefer not to send it back to Samsung as they won't accept it in the UK support so I'd have to send it back to the US support.
Anyways, if anyone has any advice it would be GREATLY appreciated. Thank you.
It's not a power but display issue. If you can hear the sound in the background or press volume up and down and you can hear the sound, it mostly has the loose LCD cable.
Search Youtube how to open your tablet, the tool you may need is a guitar pick.
Disconnect the battery first. You only need to disconnect and reconnect the LCD cable. The locking tab is at the top of the connector, lift it gently up 90 degree and be careful, otherwise you might break it. All connectors are unlocked by lifting up from the top 90 degree and they're very easy broken if you're not careful.
Here the LCD cable ( black ) is just slightly below the line on mainboard, you will have a black screen

This one, the LCD cable is fully seated.
This connector is weakly hold the cable, you can pull the cable out while is in locking position. So you need put tapes over the connector and cable to hold it firmly, another one at the center of the battery to prevent if from moving. Battery should be back, otherwise you'll see nothing. Test by plugging your charger and press the HOME button, you should see the battery icon briefly if everything you're done correctly.

Hey, thank you for the reply! I opened up my Tab and it was loose. Unfortunately being a complete beginner I think I f****d it up and ruined the cable - imgur dot com/a/kvP8Z ( I cant post links)
Am I going to have to replace that now as it still doesn't seem to be working.. :/
Other than that I can't see anything else that might be wrong with it whilst it's opened up??
Again, thanks for your help, it's MASSIVELY appreciated!

Speaking from experience, you are in a tight spot now... if you did what I did. I had a Tab S and I opened it up to replace the charging port. Different pieces, but same steps as listed above. I broke the locking tab that holds the cable down. My only recourse was to replace the motherboard. Long story short, it was easier (and not much more expensive) to buy a new tablet. I know this isn't what you want to hear. Sorry about your luck.
HOWEVER, my problem was with supply, my S was old and I couldn't find a new motherboard and the website I found was "out of stock" of used ones priced high. Since you have a fairly new device, you might be able to find a replacement much easier.

I don't think that the locking mechanism is effected, but I scuffed the black LCD cable thing and it's now showing some of the bronze beneath it.. I thought that maybe that was causing it to not just work now that the cable's in the correct position? If it's the case that I've completely ruined the device and that I can't do anything with it, I don't know if I can justify getting a second one in such a short space of time. :/

That's good. You might be able to find a replacement cable or even just put a small piece of electrical tape over the scuffed segment... Depending on how deep the scuff is. There are a lot smarter people on this board that may be able to advise you better.
Just searched "galaxy tab a 10.1 lcd cable" and they are pretty inexpensive. Cheaper than a new tablet! About $2 USD.

Try to tape the LCD cable down to the mainboard, I don't know how bad you damaged it. This LCD cable is not easy to take out as the section connected to LCD is under the frame.
In order to take it out, you have to cut the frame. It's easier than heating up the whole assembly to remove the touchscreen and LCD from the frame. Newbie will most likely damage them in this process.

See Sn0wtek... A much smarter person than me!
This is the proper way to secure LCD cable both SM-T580 and SM-P580, without tape the cable will loose again.
This is another bad design from Samsung, the motherboard has no screw to hold it at the bottom. It can wobble easily, that's reason you need tapes to hold the LCD cable to mainboard , prevent it from moving out of the connector.
