Hi.
Had some time to play with G-Tab and took it apart. Not a big deal, only 4 screws.
What I noticed was the empty socket on Motherboard with corresponding mounting screw holes on the chassis in between the battery and the MoBo. Several thoughts come to mind.... Is there a GPS module that can be installed internally? Or SSD?
Didn't take pictures thou... Big mistake, but I promise I'll take it apart again and post pix on the weekend. Hopefully someone will be able to recognize the connection and shed some light on what else could be installed and supported by G-Tab. If there was any way to get schematics of the tablet to make a little more understanding of hardware layout?
If anyone has any thoughts or knowledge, please chip in.
Thanks!

Thanks a lot!! That well explains it! So, it's a 3G module!! Sad part is, it's Verizon..... I would rather prefer T-mo or ATT....
But, oh well.. Will try to find the 3G module to play with it!
So, I don't have to take the tablet apart again. Pictures posted in provided link well illustrate and describe the hardware.
Really appreciated!
A coworker I started working with a few months ago told me about the much-better Sensation he had before his MyTouch 3G. It seems that he still had it, but stopped using it "because the screen cracked." I correctly surmised that it was a simple and cheap to replace touch screen digitizer and described to him that it was "just the glass cover" and that it was "cheap to replace." I have done many such repairs on other phones and gadgets.
He then told me that he had continued to use it until the LCD went blank. There is no reason to think that the LCD inside suddenly cracked, but I can only assume that it also sustained some kind of damage and now also requires replacement. Knowing that the LCD isn't cracked, what are the chances that a replacement LCD + digitizer will restore the phone? I'm concerned because we've already purchased a kit for $65.
Nobody can tell you that off the internet. If we do, that would be pure guess, just as accurate as you would have guessed.

Well, someone could have had the exact same problem and already tried it. I ran into people with the same problem already. I'm just looking for more because some, no doubt, have tried it and others may have an alternate explanation. Reasonable.
there is a good chance that will fix the problem. but since the LCD was working for a while until it blank out, it is possible the problem might be with the circuit board. only way to know is to try it out.

The LCD could go blank for several reasons. Faulty LCD, loose cable, faulty board etc. etc. Even if someone had the same problem, the reason for it could be completely different, thefore this wont help you at all except for giving you hope. If this is what you need, then i would say "yes, the change of lcd & digitizer should fix the problem" but you never can be sure unless you try When you start the phone, do you hear the startup sound? This could at least indicate that the phone isnt completely faulty.

The plus side is that you can't make it worse. So you've got nothing to lose by trying to repair it, other than the few bucks for the parts.
Well, I took it apart to re-seat all the cables and it's still blank. Reading online, I see that a lot of dropped Sensations/Pyramids develop a loose/broken SMT capacitor component near the headphone jack, but I'm not registered on any of the forums I see it discussed on and I can't see the pics. They describe a slightly different problem anyway (screen goes blank after standby). I needed sleep, so I put it all back together and I'll check that out when the parts get here. My hunch is that the LCD panel is fine and that I'll have an extra, assuming the capacitor problem is fixable. I've done some delicate soldering work before but I can't really say that I'm good at it! I didn't see any loose SMT components rattling around so I hope it didn't fall completely out somewhere.

Thanks but it's almost $70 for the parts.
Works great! Well, it had the touchscreen sensitivity issue pretty badly but the T-Mobile OTA update fixed that. Transferring all the adhesive bits from one screen to another was down-right frustrating, but I pulled it off and I only see a single spec of dust inside. The dude will be thrilled. I broke the earhook on my Looxcie so I did not make a video but it was full of me tearing and ripping the things anyway and not a good example of how it should be done!
FWIW, there was no way to remove the old screen without denting up the backing plate and prying the heck out of it to free it from multiple adhesives and glues, so I would not have had two good LCDs after testing the replacement even if there was nothing wrong with the original. Good thing it was the LCD at fault! I didn't have to drill anything like the glass replacement video I watched instructed me to do. They didn't realize that the LCD removal allows the flex PCB through just fine. I forgot to thread it back through before seating the replacement LCD in the adhesives and tape left-overs but it flexed enough to allow it through without removing, which was quite a relief after seeing how the original fared after being removed.
Hi to everyone whats up i have some Q and i think this is for DEV section, here is the tHing i opened my phone to clean it all and i have make ONE BIG mistake i acidently broke two small peaces ( look at picture i marked it with red circle and here is link to biger picture so you can see beter http://guide-images.ifixit.net/igi/nvbKG1sC1T3xY66q.huge ). Now all work fine but Camera, actually it is working butt when i take picture it doesn't save picture it just show me a gray instead of PIC and just FC/Camera stop working and funny thing is when i use camcorder it works and make a movie and after stop it also close cam FC/etc BUT IT SAVES MOVIE and i cam watch it so PLEASE TAKE A LOOK AT PIC AND PLEASE A LEAST IF YOU KNOW WHAT THIS PARTS IS I MEAN WHAT IS THE NAME OT THEM WRITE IT DOWN ON THREAD OR PM ME SO I CAN FIND THEM OR TAKE THEM FROM OTHER MOBO AND SOLDER THEM TO MY MOBO AGAIN THANKS ALLOT

I was have the same problem with pictures (gray). I've renamed "DCIM" and "Camera" folders in SDCard for backup it, and pictures now works fine. Maybe you should try it, before do some hardware things .
Good luck! Hope you get it fixed. This thread belongs to the Q&A section, this isn't android development is it?

If you already identified the component and have the necessary equipment (the thinnest solder iron and tweezer that you can find, as well as steady hands), all that's left is a good luck, man.

Just solder them with a fine tip on a 15/30w soldering iron. Done it a few times, SMD components are small, but not impossible. Have something to hold the component down and a magnifying glass will help.

How about this:
Take a piece of copper wire about 1mm in diameter.
Wrap it around the soldering iron end.
Wait until it heats up enough.
Now you have your own micro-soldering iron!

You really shouldn't be playing around with the motherboard if you aren't 100% sure what you're doing. But seeing as you already have, the best bet would be try contacting Samsung and if if they'll fix it under warranty. Just be sure not to say that YOU messed with it. Just put everything back to where it was and make it look like you didn't open it or touch it. I just got mine back from warranty for a faulty motherboard so I know they can replace it easy.
Good luck,

Hey guys my screen has been broken brutally.. My younger brother just threw it away!
So the touch doesnt work now but i guess everything else is fine. The volume and power buttons work fine. But the tough or the capactive buttons dont respond.
From what i have researched since the touch and the lcd are glued both will have to be replaced together. So i researched and found an estimate of 65$ for a new digitizer + LCD. Now the problem is even if i order the tough and lcd i dont know how to fix it. I saw the ifixit teardown but dont really understand much since there are no detailed steps in it.
I am not going to repair it myself, will repair it from a local repairer but i am pretty sure around here people dont even know what this phone is, so i dont wanna risk directly handing over it to them. If anyone of you all could guide me with a step by step procedure it would be a greattt help! Please help me guys want a good solution for this precious phone!
P.S i dont wanna send it to Oneplus since only the shipping would cost me around 100$ and 100$ more for the screen replacement.
and please dont advice about how i should have taken better care! I had applied a nilkin tempered glass protector but since it hit the wall at the sides it dint really help!
I should have had a case! </3 i was on my way to buy one
Step 1: Open The Back cover
Step 2. Remove the screws
Step 3: ...... please guide me about how to proceed with detaching the screen.
i would b glad to share one of my sharable invites with you if you help me with it or a video would be just paradise! :good:
I
Where do you found LCD + digitizer for only 65$??
The less expansive i've found is on ali and it's around 125$...
I'm interested too as i broke my oneplus as you did... Except it wasn't my little brother who thrown it away, it was only me letting it down to the floor...
I think, about the procedure shown in ifixit, it is doable fixing the broken screen... It just seems to ask proper tools ans patience... And a heat gun... (Or hair dryer!!)
Procedure?

ifixit doesnt show any procedure.. m pretty sure you dont need to go through the first 19 steps before you an finally dettach the screen. As far as i know most of the steps mentioned in the middle are not required. So i want someone to assist me with the required steps.
heat gun? i dont think its needed that would be needed if the digitzer and lcd were seprate. Since thats not the case it should be even easier. Oh yes we need the right tools but i guess a local repairer would have them anyway. i would just want the procedure so i could guide him since he wont know about the procedure, about this specific device
I got the 65$ one from ali express too,
go to the site and search for oneplus one digitizer. There are a list of options. Cant post links!

I don't think that you will find someone who can help you. You will need detailed instructions and images, and I don't think anyone has documented a thorough disassembly yet. You can check on YouTube, it's been a while since I've checked myself. I did disassemble one of my OnePlus One's a few weeks ago because the motor was malfunctioning, but instead of trying to fix it I simply returned it for a refund.
I just need to know how is the screen attached

i dont wanna know all the steps. I just wanna know how is the screen attached. I think it should over all be pretty standard for all phones. So should not be much stress for a local repairer. And from what i have read when the digitizer + lcd are glued it is a very easy job to replace them together. I just want to be sure from my side that say the screen needs to be attached the same way that a Galaxy S2 display is attached to the phone. Then i can just ask the repairer if he would have known how to repair a GSII.
I really cant ship it back to OPO its gonna be almost as much expensive as buying a new One!

Did you only buy the digitizer? You should have bought the screen and digitizer that are already fused. It is absurdly difficult to take off only digitizer and broken glass cleanly. Believe me, I've been repairing things all my life and this is one of the hardest things to fix.

I haven't bought it yet. But dont worry i will b buying the digitizer and the LCD that are already fused together.
But even attaching to the phone is also kind of a challenge right?
guys,
Anyone please suggest regarding how durable and trustworthy are these digitizer +lcd combo that are available on ebay.in?
Can i purchase them? I broke the screen badly and waiting for a replacement. Found a replacement on ebay.in for apprx 100$. Thats fine with me but need suggestions from users who already tried using these screens...? can i go ahead and get it done from a repair shop?
Hi. I have a Sony Z3. And the backlight had gone. I have had experience and removed the backlight resistor from the main board and just bridged the two connections. This solved the issue. I have also done it with the z,z1 and z2.
But I was wondaring as I dont know much about circuit boards. Will just bridging the connection cause any damage? Will it last long?
The phone is already out of warrenty.
I have soldered a Sony z and it has lasted a very long time. But can I expect the z3 to be the same?
Thanks for any help and wisdom!!
Hi
Can you take picture i have 6603 and same problem please help me
You have a two year manufacturer's warranty with Sony, and you don't need a proof of purchase.
Return it - unless you've voided it yourself.
dear
The warranty is void
I replaced lcd and frame when i did the brightness no work more
I need resistor location
Hi I've don't it a few times and it always worked. I don't have one to take a picture. But it's near the bottom left of the board . The component is black and has a little V in white on it. If the backlight is gone this component tends to have a burnt hole right in the middle.
I always need a microscope but if you have mega good eye sight you should find it. Hope this helps!

Do you happen to know how to fix a Xperia Z3 Compact with a similar issue?
I replaced the screen on my Xperia Z3 Compact and now when I turn it on nothing shows up no image and no backlight. But I can hear that the phone is working. Touchscreen makes clicking noise, and vibrator motor makes noise when clicking home button.
How can I make a jumper?
I have this prob too after replacing screen. First, the phone would work only if the the two final screws holding the assembly weren't screwed in. Now it doesn't work at all.
sent here from a member from another thread~
Sorry - but I was sent to this thread from a member in a reply to a thread I posted last week - they said I might have a better chance at finding answers here.
Here's my question (copy/pasted):
Hello, please forgive me if this is not the appropriate place or generally not the correct type of question to ask, I am new here & was directed to this site from my former trainer as a means of educating myself on the problems I am facing..
Let me first say that I am new to micro soldering, and have only been a certified micro solderer for a few weeks now.
I work for a privately owned company of mobile technicians and I am the sole solderer on staff. My company paid for my training and I would say I have a fairly decent grasp on general soldering repairs.
That being said, I am facing some big issues with backlight repairs. I have been successful in replacing components that have been obviously damaged or missing, but when all responsible components are seemingly in place & in working order - as far as I can see under the microscope - I cannot figure out how to diagnose which of these components has failed to communicate with it's sisters.
I have read a great deal online about jumping components, but I am really very much as a loss as to how I am supposed to be able to figure out which one(s) of these to jump or how to tell if they are in need of replacement - when no physical damage is present.
Any and all help in this area is welcome - I would really love it if I could get a better handle on these types of repairs.
If this topic already exists somewhere, or there is another place I should be looking - point me in that direction & I will follow.
Thanks~

Would you happen to know the location of the xperia Z1S backlight fuse also?
Hi there,
I have done lots of cellphone repairs and I know my things about smd soldering.
To answer your question : Will just bridging the connection cause any damage?
The answer is yes and no. By bridging the resistor you won't damage the Phone but the only thing you are doing is taking a safety measure out of the circuit. Next time there is a problem in that bridged circuit there will be no fuse more to blow out and the damage will be done to an other component in that circuit, most likely the power management IC, and those are way harder and have a much more higher fail rate in replacement.
So if you can find a replacement resistor on Ebay i suggest you buy it and replace the broken one. When replacements are not sold, we allways try to take them of another damaged motherboard we have laying around.
If those 2 options are not possible, bridging will be the only solution.
Grtz...
