Screen not working after mainboard replacements - Galaxy Note GT-N7000 Q&A, Help & Troubleshooting

I ordered a mainboard and installed it. I almost know sure I did everything right. But the screen is not working. Touch and a black screen... I think it is the connector but don't know sure... Anyone with suggestions?
Edit: It works fine with the old mainboard.

its simple..just check the lcd flex plug... make sure its pressed into position correct... if it still does not respond, then you have probably damaged the flex somehow... a crease.. a very small tear... a pin or pins in the plug itself got pulled loose... etc... it doesnt take much...

Tanks for the response. I know sure it is connected properly. And if it's broken it's very hard to fix I guess...

What is the problem with my display?

A couple of weeks ago my screen broke while I sat down with tight jeans on a chair, while having the phone in my pocket.
I ordered a OEM screen replacement and today i thought i managed to replace it.
The problem is that the screen does not work, I can hear the phone turning on but the screen just flashing the same yellow/green/white color whatever i do.
Here is a link to a video of the screen. youtube.com/ watch?v=RR_6fwPgJLc
Does anyone have a clue what could be wrong? I was very careful during the whole replacement procedure so i do not think i broke the screen by my self while i was replacing it.
Thanks in advance!
In my opinion its either a faulty screen or the flex cable was damaged.

Thanks for your response.
yes, my first thought was also that i have gotten a faulty screen.
Which flex cable do you mean?
The flex cable that connects the screen to the phone.

Phone fell in toilet... [NEED HELP]

So as the title says : my phone fell in the toilet... (i know so dumb)
Its already 1 week after the incident, i first waited 3 days to turn it on. Which it still does, actually everything works! :good:
But the only downside is that my screen is doing some crazy things.
So now my real question is if i replaced the LCD screen with something like this https://www.amltelecom.com/kleinhandel/products/Display-LCD-LG-P990-Optimus-Speed-2x.html would my display be normal again or is maybe a chip inside also corroded so the new screen will have the same issues too?
I tried making a screenshot on cm7 and when i looked at it on my pc, it didn't show the striped and flickers.
So what i think is that theres some water behind the screen wich makes it flicker all the time.
So what do you guys think about it?
Anyone had some expierence with water damage?
Hope you guys can help me!:highfive:
Thanks all!

My usb port is having some issues too now, sometimes it does work and sometimes it doesn't...
Even if I let it stick in the same position sometime it does work and after some time it won't some I'm guessing replacing my usb connector too would have some effect.

Hi there!
I don't know about the water damage. I would take the phone completely apart and let it dry like that for a few days. But again, no experience in that.
With the USB connector, I had this with my phone once I thought, turned out to be the USB cable, and not my connector. Be sure to test with other cables first before replacing your USB connector.
Hope it helps!

Did you take your phone apart to let it dry? There might be still some condense in there.
I can't help you unfortunately, although I wish you good luck, as I have nearly had that accident too, not even once. lol

Why don't you try taking the phone to the service centre and see what they have to say. If they can fix it out by service then you might save money and they are professional's.
All the best and i hope it does not hurt your pocket more.

I can recommend the second one (first seems very long).
Difficult steps:
1. remove digitizer with bezel (frame) from case, use credit card (preferably old one),
2. avoiding dust between digitizer and lcd screen - use gloves, and
3. putting back digitizer and bezel - start with fitting micro-usb input while checking all buttons. Be careful, micro-usb entrance easily gets damaged!
Furthermore, I recommend to put wrap around all your toilets
Good luck

Touch not working after screen replacement

Hi, I recently attempted to replace the screen on my Moto G 2014, and now the touch doesn't work. The first replacement didn't work so I ordered another one, but that one doesn't work either.
Am I missing something? I followed the instructions on YouTube to the dot and still no touch response.
On another note, the Amazon listing for the part says XT1063. Wouldn't it work on the XT1064 as well?
One would think so. You didn't bend any of the pins on the ribbon cables did you?

I connected the ribbon cable before I placed the board back into the frame. But either way the cable has to bend. That's why I connected it first and then positioned the board over the screw holes so it would bend naturally.

Sorry, I meant where they make their connections. I would go back and take a close look at every plug even if you have to use a magnifying glass. It sure sounds like something isn't making a connection.

Would another part not connecting properly cause the touch to not work? Also, does the back cover need to be on it for the touch to work? I noticed there are little copper plates on the back cover. I've tried testing with and without it screwed on. I'll take a look at the plugs.
The plugs and pins look fine to me. Nothing bent.

I'm guessing that you replaced the entire screen assembly and not just the glass. If the silicon adhesive between the glass and digitizer isn't on properly, then it's not going to work. If you bought the entire assembly assembled, then that's probably not it. If the entire screen assembly is good, then I'm still betting on some type of connection or broken wire problem. If those ribbon cables get pinched or pulled on even a little, the wire inside gets broken. I don't know how you would be even able to test the cables without replacing them. It could be so many things, I'm out of ideas.

One screen was without the frame, and the other was the whole assembly. I guess it is a broken connection somewhere.... I tried being extra careful
I was replacing the screen for a friend, but I guess I'm going to have to buy them a new phone instead.. D:

Is your Moto G definitely 2nd generation?
Maybe you should have bought the screen for XT1032?
Did you carefully lift up the little lever on the ZIF socket?
And then press it back after fitting the ribbon end?
If the lever breaks then it won't work.
Did you find a solution? I have the same problem
Unplug battery. Plug it again... Worked to me...
Disconnecting the battery and reconnecting it worked for me.
Thanks for the advice!
Help me as well

Screen Touch not working properly - I sat on my Honor X2
Hello
I sat on my X2 GEM-703L under several pillows - bend was 1/2 inch from center (top/bottom were 1/2" lower than center - approaching U shape - very shallow though) I carefully bent it straight (there is a small link in metal frame right side just above center button. Everything else seems to work beside the screen. I will push "4" and the key adjacent character is recognized also it will type on its own or type 3-5 characters when I only pushed one...
Questions:. Does this sound like touch screen Replacement will fix these issues??? Or is thier additional interface hardware attached with the touch screen, or both?
I am hoping it's just touch screen replacement - I really like that phone (even with texting recieve not able to be solved)
Thanks for your help

Cracked screen

I recently dropped my Z1 and both the glass and the display are broken. In addition, rear camera stopped working. Did the camera thing happen to anyone with cracked screen? Is it worth repairing or not?
I attached some photos.
Camera thing mine did not happen
I find the camera connector really easy to disconnect soo I think you can try to dissasemble and replug the sensor if that is the case.
And uhh on Ebay you can find glass+lcd together for like 30 usd $ (shipping included) I think it's still reasonable to fix it for that price
But if you want waterproof! Make sure to get a sort of sticker for it!! You need like 3 different ones for the screen. If you are trying to fix the camera, it's 2 kinds. They are usually blue sheets
Mine is broken right now xD I ordered the screen but it did not come yet
btw that's what I bought: http://www.ebay.com/itm/131397630061?_trksid=p2057872.m2749.l2649&ssPageName=STRK:MEBIDX:IT

Thanks, but I doubt that the LCD you posted is genuine it seems too cheap and there is no sony logo in the picture. And I am not sure if I would successfully repair it on my own...might as well buy the LCD and have it replaced at the service center.

And the fact that the camera connector is easy to disconnect...do you have any source or you disassembled by yourself and saw it?

It is nothing unusual that these connectors are popping out when phone is dropped. I saw it in a few of dropped phones.

Replacement Stylus Flex

The SPen on my Note 5 has not worked in a while. When I spoke to Samsung they said it was "moisture" damage. Confused as the water damage sticker does not show that the phone has been wet. Regardless, the *#0*# Spen test showed no response to the Spen on the screen. I decided to order a new stylus flex (stylus digitizer) for the phone. I received it today and plugged it in without taking the LCD off, just to see if it worked or not. I moved the Spen around near the flex digitizer but cannot see any response on the screen.
Does it have to be pressed up against the screen to show response? Or as it also not working and the fault is in the motherboard.
Any help is appreciated.

Just to make sure; have you tried another stylus or tried your stylus on a different device?
