I am working on a G1 and i'm not able to figure out what's wrong. I did a hard reset and I even removed root and flashed the original software. I have already replaced the digitizer. What i can see is that the flex wire connecting to the board and and the LCD is damaged but I'm not sure if that would cause it not to work. Before I buy the flex wire and waste more money, is there anything else that could cause the screen to not respond to touch?
What do you mean by damaged? Is the flex ripped? If it is, the only way to fix it is to replace the flex ribbon.
Its folded.

1.the flex cables can be bad without any physical damage.
2. in some cases, the board itself can loose the touch function (not related to the screen or the ribbon)
the only true way of diagnostic is by process of elimination.
If you have enough spare parts, figuring it out is quick and easy. (and if you dont, good luck)

So I was done fixing the screen lift problem I had with my device and noticed something fell from the device. Turn's out that the spring pin for the NFC broke (Please correct me if I am wrong)
Here are some pics:

I am planning to solder or just leave it that way as I never use NFC (specially I'm from the Philippines and NFC is not the trend).
I'm not really sure of what I am doing so some please enlighten me. Is it safe to solder it? or just leave it that way.
Thanks
I would not try to solder the pin, unless you can determine the motherboard is not a multilayered board.

Thanks for the info... I do not know about multilayered motherboards so your advice is really helpful not to eventually screwing the whole device.
Any more input guys regarding my problem?
I successfully removed the Qi coil off my OEM Samsung back cover yesterday. Because the contacts/pegs (whatever they are called) are now too long, I tried to trim them, I have overtrimmed them. So to remedy the short contacts, I tried to put solder on them, but my soldering skills are not good, and thecontacts came off, they are very delicate...
I want to repair it but I don't know if the parts I am looking for is available and I also don't know what they are called.
Here is the damaged Qi coil

And I want to buy contacts similar to these:
I don't know what they are called, or if there are better options, please let me know
I managed to salvage some of the pegs from my old S3 Qi receivers, and soldered them to my Note 4's receiver a few days ago... but no luck.. It seems even with soldering, there seems to be no contact.
Make sure they aren't short circuit.
As you said before that your soldering skill is not good there is a chance that the result is shorted.
My I9505 screen was broken, so I attempted to replace the screen. After doing so, I noticed that the pins (on motherboard) to which the display cable connects too looked to be damaged.
After everything was connected etc. I then turned my phone on. And although sound emerged and lights lit up, nothing appeared on the screen.
(I'm assuming the problem is with the pins described above)
A picture of the motherboard is below.

Is there anything that can be done to repair the motherboard, so images will be displayed on the screen. Without paying for a new motherboard?
P.S I have tested the new replacement screen on another I9505 and it worked perfectly ( so the fault is definitely with my i9505's hardware)

any help PLEASE!
You'd have to get a replacement motherboard for your device. As there is no way you can fix that yourself, unless you are a certified or skilled electrician.
Ok man dont worry just search the schematic of the board and you will find there the number of those 2 pieces. It will be kinda hard to buy them but... if you have it then you'll need a soldering station with veri fine tip or you can solder them with hot air soldering station.
Hello and thanks in advance for any help.
I am happily running PH-1 with stock system, no mods of any kind as my daily, and now on my 3rd replacement screen.
This time around, one of the surface mount components came off (glue job gone bad, long story) and I want to replace it, myself, which I am able to do though I need to I.D. the component.
Attached pic of my connector, and showing which component that I'm needing to ID.
My screen works though I've no touch-response and I'm thinking it must have somethin to do with the missing part of the circuit.
Yes I've looked at the possibility of resetting and forcing a recalibrate etc... I didn't have to reset with my previous 2 replacements. So first I'd like to take care of this item just to put it aside, hoping that it's the problem.
Again thanks for any help, I've searched for quite some time and have not found schematics nor a hi-def enough image of that area.
