No Bars After Replacing Digitizer - LG Optimus 3D

Hello! Tonight I replaced the touch screen digitizer in my phone because I had badly cracked my last one. The new touch screen works and the phone is fully functional now with the exemption that the phone now says it has no bars and it doesn't appear to be reading my sim card now.
Can anybody give me advice or insight into anything I might've done wrong re-adssembling the phone ?? Any suggestions for getting it working?? Im opening it up and re-connecting everything to make sure none of the connections were loose and thats not causing the problem. Also, using a different sim card did not help.
Edit: I reconnected the connectors on the motherboard and sim reader and it still is not getting service. I guess Ill continue to fiddle with it until somebody throws some better suggestions at me.
Another edit: You guys can delete this I fixed it. I had folder this little connector attached to a wire under the motherboard...haha.

make sure all the ribbons are connected there is quite a few to push down and m,ake sure there seated properly

HTC Fuze, Black/Blank Screen. Everything Else works, just can't see it.

Firstly, my screen does not show visuals. I can still touch the screen and make things happen, but it is just a back-lighted black screen. I have answered calls on it and such. Basically I'm returning it and getting a new one.
Since I am getting a new one, I want to see if anyone ever heard of this problem and to see what the cause of it is, for prevention purposes.
I didn't get it wet (the white sticker in the back is still white.) Though I have flashed PROven ROM to it a couple months ago (it's a great ROM by the way), but could that have messed up my screen?
I also wanted to know since I can't see the screen, would I have to, for warranty purposes, (blindly) reflash to the Stock ROM?
Thanks in advance!
Yeah, you probably oughta return it to stock configuration (good luck on that!). If you're really lucky, that might even fix the problem. Have you done a hard reset yet? Might be worth a try, although it certainly sounds like a hardware problem.
Sounds like the flex cable has gone bad
Exactly same thing happened to me this Tuesday. Luckly I backed up info to memory card using PimBackupV2.8 with remote control software on my PC. With the remote contol tool, I could see everything as if on my phone and icons are clickable.
Hard reset did not fix the issue. I then flashed the shipped official ROM and stock SPL for warranty purpose. Will send the phone to them today for repair.
mine also like that..
from vodafone also..
the things that make me panics is the phone become hotter and hotter.

Summer is coming...
Sometimes they make updating phones too easy......
The back of my phone often gets hot I have to use the edges to hold it even though it was not a hot day and it is in my pocket.
blank screen
ya so my screen is blank white
but everything else works
i've heard something about this being a faulty "flex cable"
how can i fix this?
thanks so much for your help
how do i fix this???
did you eventually find out how to fix this/???
u ever end up fixing that? how?
thankss
Mine was still in warranty so I rang Vodafone. They sent me a special delivery envelop the following day. I sent it back to them. The following day I got a text message from them saying they got it and was working on it to fix the fault. The next day received another message saying the device was on the way back to me and I should receive it the following day.
Actually they sent me back a replacement
So.. basically.. is this a faulty flex thing?
I had the same problem for the last week until today i was about to buy another one since i dont have any warranty for this one.. I searched google and saw somebody say that just putting a business card between the keyboard and the lcd and then slide it and it works so far
hope it helps everybody
Ack! my Fuze, which I got off eBay a few months back, just went black too.
I'm not exactly sure whether it's the LCD or the flex cable, but the fact that the D-pad backlight also has become intermittent makes me think it's the cable.
So has anyone attempted the flex cable repair themselves? I see you can buy the cable for around $40 and the LCD for around $80 from Hong Kong.
Maybe this is a sign I should just get an Android device.

Did you end up fixing it? I have the same problem.
same thing happened to me Twice.... in my sleep overnight. I LOOOOOOOOVe my raphael but man this was the last straw
This maybe of some help for those of you with blank screens. I bought a Touch Pro on ebay that had a very dark screen, occasionally you could just make out some icons being displayed. Using Mymobiler showed that the basic system was working, as was the touchscreen. Other symptoms were that the camera would not work and the keypad lighting was intermittent. Sometimes on connection to Mymobiler a dialog box would come up saying there was an error with Microp?!?
Despite cleaning all internal connections and ensuring they were correctly and securely made the problem remained. I then noticed that the small camera used for video calls (in a socket on the main flex cable) looked very dirty and corroded. I removed the camera module and, using a fibreglass brush, cleaned the contacts on both the socket and the camera module. These were very badly corroded with verdigris.
On putting everything back together I was most surprised to find the screen was now working, as was the main camera. Unfortunately the ROM that is loaded doesn't seem to have any facility for checking the front video camera. There are still problems with sound - both the loudspeaker and the headphones seem to be dead and I have not had the opportunity to test GPS, Wifi, bluetooth, buttons, etc, however I will keep working on it.
Hope this is of help to someone.

Can someone who's had their fone apart help me out?

My girlfriend's fone had the screen replaced today and i picked it up and bought it home, we've put the sim card back in but its not showing any service. Its recognised the card and the sim contacts but won't connect to the network and if I search for networks in settings it just says error searching
Any ideas? Have they left something unplugged inside etc?

They could very easily have left something disconnected, but I'm not sure exactly what it would be. My DS is currently apart while I wait for a new LCD screen and it is in a load of parts. Although it is quite complicated, the only real culprit would be the little pop-on aerial cable that runs from the main board down to the aerial connector board.
Your best bet is to take it back to the shop (with your SIM card) and ask them to fix whatever they've screwed up for you. Taking it apart is unlikely to be a good idea if you needed to take it to a shop to get it fixed in the first place.
Ah then I'll take it back to them tomorrow! Thanks!
I just wanted to know what it would be if i take it back

Signal Problem after dropping phone

Hey guys,
so, few days ago i accidentally dropped my pohne; well not really dropping it but i didn't see something on the ground and fell over it... Phone was in my pocket the whole time... i didn't check it afterwards cause in the middle of the night you can't really see anything, and i thought in my pocket it shouldn't get damaged. So yeah... the morning after i recognized it doesn't connect to my provider anymore, tried out several other sim cards, no success. Most of the time it now just shows the empty signal icon, sometimes it connects to my provider but when it does signal is very weak and only e network h/h+ doesn't work completely, but it disappears after few seconds.
What i tried so far:
- reflashing ROM with fullwipe (/system wipe aswell); thought it was a rom derp first
- opened the phone and disassembled it, checked mainboard, usb board and antenna for cracks etc. couldn't find anything... looks like new, the only "crack" is my volume keys seem to have taken a bit damage and are now split in half... everything else is fine, screen no scratches etc
So yeah now i'm quite clueless what could've been damaged... since everyting else works completely fine only mobile network/internet doesn't work... could my antenna be damaged?
I thought about buying a replace antenna and testing if that works.... any other ideas?
Thanks in advance

[Q] No Service after Battery Replacement

I changed my battery in my Nexus 5 today and I thought everything went smoothly until I booted up and had no service. Does anyone have any experience with this problem or have a solution?
I have already flashed back to factory, removed and inserted my sim card, and tried putting my old battery back in. I didn't remove any antenna cables either (the black and white ones on the sides of the battery).
I googled and ran into this thread, but I'm not sure if the OP ever fixed his problem, and seems to have gone inactive since the post.

You probably forgot connect antenna, this is similar issue https://www.ifixit.com/Answers/View/199531/No+HSPA++since+teardown

Thanks for the reply. I made sure everything was connected even though I didn't touch the antenna cables when replacing the battery. I'm trying to figure out what it possibly could be.
Yeah something isn't connected properly
I made sure everything was connected properly. I only removed the battery cable and the ribbon cable next to it to replace the battery. I'm really wondering what it could be. The black and grey antenna cables seem to be properly and snuggly connected. Is there something else on the phone that can effect cell service?
The phone reads that a sim is inserted and can read the phone number off of it, but cannot draw cell service for some reason.

No signal after screen replacement

Hey guys. So the LCD went out on my 3a a while back. I bought the parts and replaced it myself (I've done these before so I wasn't lost). I ended up replacing my battery, loud speaker, fingerprint scanner and a couple other parts as well, because why not? Also replaced both antenna cables (white and black). Anyway, after getting everything all put back together, I installed my SIM card and it recognizes there's a SIM installed, but signal never comes in. No cell signal or internet. Any ideas on a cause or a fix? I triple checked everything before setting the screen in the adhesive and everything was connected correctly. Thanks in advance!
Silly question but did you try to restart the phone?
Yesterday I had an accident and my phone slipped from my pocket a screen/glass got broken :/
Can you tell where did you bought the screen and is it the same quality as original one? Thanks in advance.
I've restarted, flashed back to a previous update, taken the latest updates. You name it. I've tried everything that I know to try. The phone recognized that there's a Sim card installed but just won't pick up signal
