Chances that an LCD + digitizer will fix this?

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.

[RESOLVED] HOX AT&T US, pj83100 POGO

Alright. Apparently this specific phone has weird or messed up POGO pins. And I really need some help.
I've searched but can't find anyone with this issue.
There are supposed to be 5 pins total (http://forum.xda-developers.com/showthread.php?t=1611116). On my phone, there are 5 positions, but the first (GND) is blocked off by the outer plastic of the case. I picked away the plastic to find no pin present, just a plastic stub from within the phone. And while I will (next week) be taking the phone apart to do multiple things (replace broken digitizer, & upgrade battery, replace back-door), surely someone knows something about this?
I ordered a Seidio Innocell case to further enhance my battery life. It is the version marked to support the AT&T variant. However it does not work. I would think that the GND connection is unnecessary to charge the battery (unsafely), so I can only assume that the 4 pins available are not as identified with other variants. Perhaps the 1st pin is dislodged by some means, though that does not explain the plastic covering it... Other than perhaps a manufacturer defect that I never noticed?
Can anyone assist?
Like I said I'll be opening it up soon, so I'll probably modify the back door to support this Innocell casing anyway. So any information would be useful as to what might be going wrong here.
*EDIT:
I can confirm after picking away more plastic, that there IS indeed the 1st pin (you can see it in attached image if you look closely), and that my phone was poorly manufactured. The pin is shoved beneath the casing due to lack of clearance when it was assembled. No wonder. Charging still does not work, so I'm wondering if there is a way I can manually test these two pins (#1 & #5) for charging capabilities? 5v battery and two wires perhaps?

This belongs in the q&a section, not sure why you've posted it here?

My apologies, first time posting. I read the posting stickies, and did not think to post it in the appropriate location.
This phone was purchased from Walmart, with the related AT&T contract. One month before they released the OneX+, what luck.
My battery is at post office now, should arrive later today. I'll install and update my post, though I believe I'll be solving my own problem & answering my own question soon enough. Completion sake, anyways. The pins do work, i sent voltage through it using a multimeter, and android notified me I was using an invalid charging apparatus (incorrect mwa i guess? was @1.5v). SO that's good news I suppose.

Wow, I've never seen a new Evita with such a serious manufacturing defect like that. You should swap it out under warranty.

Haha i know right. I just opened it up, all 5 pins are available on the motherboard's bottom connector(radio/pogo/buttonLEDs). But indeed, they did not properly cut the 1st pin's plastic. Nor did they insert the actual pogo pin on it, which are both back-door flaws. Back-door assembly line failure - lol Sounds dirty.
Well all is well now. I used a HOX+ back-door instead, cause the red on black looks nice. SO I didn't have to rig my own graphite onto the plastic. All 5 pins working perfectly. Attached some photos so you guys can see what I mean. Take care all, this issue is now resolved

HTC M8 GPS problem (hardware issue)

Hello, I have a problem. Hoping someone has an answer. I have a Verizon HTC M8, yesterday I decided to disassemble the phone to just see what the insides look like, I didn't touch any other part, I tried to remove the top motherboard but I stopped because any further would damange the top board. Anyways, the GPS was working fine until I took the unit apart.
The problem: GPS location on Google map is at least a block off (tried different map apps, all are offset) and is facing the wrong direction. And GPS following is very very slow. Now I don't know if it has to do with an GPS antenna or what, maybe one of the prongs is not touching antenna, I've taken a photo of the phone from inside and I would like to know which area of the phone is exactly the GPS or maybe causing the problem . I've also attached a photo of the GPS problem, you can see in Google Maps navigation the pointer is wayy off the direction area. Please advise.
Question: What part may be causing the problem? (my guess is its the copper prongs from A-G).
Please help.
Thank you!

In my opinion, this phone has kind of wonky GPS reception anyway. It's hard to tell exactly what's causing it, but my guess is that it has something to do with an unwanted contact, or the antenna itself, touching the metal casing directly. Also, You may have possibly loosened the connection of the GPS antenna when you played with the motherboard a little.
I'll try to find some better board schematics from the motherboard, maybe tomorrow when I have time. I haven't really been able to find some good diagrams on the actual phone internals itself. This phone is really difficult to take off and not too many people attempt it.
I would try to make sure that the internals are properly shielded when you put the case back on, and try to keep all of those contacts covered as much as possible when you throw the case back on. See if you get better GPS lock or if it fixes it all together.
Edit: Actually I changed my mind, I think all those contacts are supposed to contact the case to amplify the signal. Try to get all the contacts to touch the case as much as possible when you reassemble it. I think it's either the connection from a-g area, or on the bottom half k-n or even the q connector. Is your WiFi or NFC giving you any issues as well?

@ Badusername, Thank you for your reply . Yes everything else (wifi/nfc/bluetooth) works perfectly fine. The accelorometer seems to be fine as well. Only part I try to remove/touch was from A-G area motherboard but that was held with adhesive so I didn't touch it any further, I didn't touch any other part. My guess is it's A-G area but not sure exactly which one is the GPS antenna so I can try to adjust it (if possible).

I jave the exact same problem. Did you figure anything out yet?

Any Updates?

Did you bend any of the copper prongs so that they no longer touch their antenna? That's usually the problem.

Can't find a schematic anywhere that shows which antenna or prongs are gps related so I don't know which prong or antenna to mess with. I'm surprised there are no basic schematics anywhere...

I believe it's in the top board so make sure the ribbon cable is secured and not damaged. The metal prongs usually need to make contact with the case itself which often has the actual antenna stuck to it.

Thanks for your help so far. Checked all prongs and ribbons on top left and they all look normal. They all still have a spring to them so that theyll touch the contacts on the back of the outside case. I'm out of options without finding exactly which part are gps related....

Is there any way to purchase the gold colored motherboard clips/pins that make contact with the case for the GPS module. While attempting to fix mine, the clip broke. I was looking to purchase this clip to attempt to solder it back to the board.

I'm in the same boat. I don't think there's a way to replace the clip itself, only the board that has the clip on it. It shows up as a result for "HTC One M8 Motherboard Flex Cable". Here's the one I'm buying, it's around $60. You can see the little gold tab in the picture for it. Looking at that board's location on the phone, it looks like you'd probably have to remove the motherboard to get to it and replace it. Sounds fun. I had my phone apart for a relatively simple USB port replacement.

I know this is raising the thread from death but I too broke my tab off for the gps. I was able to fix it using a trimmed piece of thin sheet aluminum that I salvaged from an old Airport extreme. I trimmed it down to the size of the tab on the motherboard and used some conductive adhesive to stick it to the solder pad that the old copper tab was attached to. I then trimmed to down to length to touch the casing when the phone was reassembled. Its been working great now for a few months and its actually a much sturdier piece of metal. I can't say objectively since I don't have data to back it up but it feels like I get a faster GPS lock now.

No display on nexus 5 even after screen change

Recently, I purchased a Nexus 5 from a friend. The screen was completely shattered and nothing would appear on the display, but my computer was able to recognize the device. This morning I replaced the screen with a new one, however, there is still nothing appearing on the display even though the computer recognizes it and there is still life left inside of it.
Is there anything I am missing? I rechecked that everything is plugged in correctly several times and still nothing. I was thinking of replacing the flex cable, but I am low on funds so I don't want to waste money if its not going to work.
Attached, are photo's of the device.
Any help is greatly appreciated.

did you replace just the screen or the whole Assembly with the lcd and digitzer?

Yes, the entire assembly has been replaced which includes the LCD and digitizer.
Once again, I'm thinking its the flex cable as bad flex cables I've had with other phones have affected the functionality of the device.

It was not.
In a nutshell, my original question was basically 'could there be another problem with the Nexus 5 that I am unaware of?' which was not answered.
The second poster simply asked me if I replaced the LCD and digitizer assembly in its entirety.
The third poster is me posting my suspicious about which piece of hardware is causing the trouble.

Oh sorry you said flex cable. I was on my app. My apologies. Honestly it could be the flex cable. I replaced the screen in my Droid 3 and it didn't work because the flex cable was damaged.

Based on your photos it looks like what you replaced should have bean sufficient but of course with electrical components who knows... I wouldn't rule out a dead replacement display either. I'm in the middle of a similar situation, returning my replacement display today and trying another.

Could be a number of things with that physical damage, not just the screen

So you were able to get a display after you changed the flex cable?
The odd thing though is that I'm still able to charge the phone...the flex cable also holds the usb port.
Anyway, I've ordered a new one so we'll see what happens.

If anyone was wondering the screen still does not work with the new flex cable. I'm assuming its a motherboard issue and am just going to sell it on eBay.
Before than, any other suggestions would be appreciated.

I bought it from him for a very cheap price ($30US). Even with it broken, I can still get more for it by selling it on eBay than I can by getting my money back.

Try to make preassure on the wide connector on the motherboard. If display backlights or displays temporarily it's micro distached pins between connector and motherboard. Heat Air is the easy solution! In my case I used hot air heatgun 350°C and 10sec on row near edge of the board. The solder melts and at that time PUT slight PREASSURE down to the connector for few seconds! It makes the legs got proper contact to the pads on the board. Solves problems with Mic and Loudspeaker too becouse it relay on this wide connector.
Good luck Tomáš

[Q] Question about One pus One logic board

Ok well here is my issue. While replacing the LCD assembly on my one plus one I managed to rip off the metal connectors(I believe they are called pogo sticks) on the logic board that make contact with the antenna's on the back cover. I ripped the ones that control the WiFi/Bluetooth and also the GPS one. I was trying to figure out how to fix this since when trying to soder them back on there was nothing they could be soldered to. I'm basically left with the empty spots on the PCB board where they are supposed to go. While looking at the logic board I saw that there are a couple of pigtail looking connectors on it that don't have anything particularly connected to them. I was wondering if I could use those to repair my connection issues. Or of any of you have any advice to give thank you for all your help ^_^
