Screen Problems and IC chips

I was trying to remove the camera on my N1 today and I broke off two small chips near the screen connector. These seem to control the red and green on the screen as I can only see blue and black on the screen right now. I was wondering:
1) If this could be what causes some people to have to much blue or red on their screens, and bad chip in my opinion could cause this.
2) If anyone knows a parts supplier who would be able to sell me these chips?
Thank you all.

Just wanted to add. Everything else works well and the phone seems fine just only blue shows up. So I will continue to use the phone and apply the blue render effect from cyanogen mod to hopefully not cause issues with the screen.

Those appear to just be resistors to me, but you wouldn't be able to change them out with a normal soldering iron.
I'd suggest you look around for someone with some tools and SMD soldering experience. Although how you managed to break off some resister packs is beyond me. Or why one would try to manually remove a camera, also beyond me..

The soldering iron won't be a problem. I work in a shop that does repairs on circuit cards. I was removing the camera since I work in a area that has classified material and so am not allowed to have camera phones.
I also thought resistor packs but did not have time to meter them so I said IC because more people may be able to understand.

Good, hopefully someone can help you fix it, or you can fix it.. Hopefully no pads were lifted or damaged. PCB repair is always fun to do, although not terribly hard unless the connection goes down into another layer. I used to do it a few years back, wish I still had the equipment available every so often.
I'd definitely verify exactly what the IC's are, but from the appearance I'll bet they are RP's, but they are making inductors in packs these days too IIRC, and really they could be anything. Markings on them should be fairly easy to look up.

Aye, I'm buying a $60 water damaged N1 from eBay and wi will try to canabilize the parts I need from there....the post said screen works perfectly. The solder work won't be difficult, different then the resistors and DIPS I usually repair but not outside what I was trained in. I will attempt to look up any numbers I see under the microscope but I had it under earlier and did not notice any numbers, but I was not looking for numbers, just assessing damage which for one maybe repairable but the other is broken in 2 pieces. Thanks for the encouragement though.

I believe these might be 0-ohm resistor packs. Use a magnifier glass and try to read any markings they have, google them - you'll probably get the component datasheet in the results.

Well after further experimentation I have red and blue working. Though I get strange artifacts on the screen.

A DHD GPS Solution( Radical and Ugly :( )

My DHD GPS contacts were broken when I tried to improve GPS function. So I used an electric wire( or any metalic wire) for antenna. I connected it to the broken position. And I made a hole over the flash cover. I made about 3 ~ 4 cm long wire come out of the hole. It works very well but ugly. Wire is flexible, you can hide it inside a jelly case, and you can take it out when necessary
Acutually no need to contact two points. Only one contact near to camera is needed. Here are some pictures instead of my poor english

You can use any conductive metalic wire for antenna.

Ugly indeed! :-\
Maybe you can mod that retractable telescopic old-style radio antenna thing on the phone casing. It'll give a retro look to the phone

I have hoped so. And some manufacturer might make a special flash cover capable of enhancing GPS performance.

TO the OP: How broken are the contacts? I also had GPS issues, then I read somewhere that you can drop on a ball of solder to fix this. Basically, the thickness of the solder ball forces contact with the antenna.

First I soldered them, but overheated to destroy the point on the cover So I created another solution. Anyway this works well. Somebody said the length of wire would be best if 9.5 cm because it fits the frequency of GPS signal. But I think it's too long to carry in my pocket. He suggested another length, 4.75cm ( 1/2 of 9.5 cm ).

What Watt soldering iron did you use?

Why would you do something as ugly as this mod to your phone when you could at least hide the wire inside? Not to mention this mod has been posted and around for awhile. This is old news. And whoever told you 9.5cm or 4.7cm for antenna was pulling your leg.

Well 4.7cm is the correct size for a quarter wave antenna. So that is correct.

GPS Accuracy 1 meter!
Yesterday on a moving( 88 km/h ) car.
I used about 5 cm long cable for GPS antenna replacement.

Do you have pictures of the inside connection to the GPS module ??

The inside connection to the GPS module.
I extracted a thin cable from a USB cable( including some thin cables inside).
I tied the cable to fix it tightly on the flash cover. And I made a hole over the cover.
The flash photo uploaded is an old one. I broke several covers : (
You can connect it to only single contact. But I think connecting two contacts would be better.
The cable is very thin, so you can hide it inside a jelly case. In my case, eiven if it is hidden inside, GPS signal can be detected( but accuracy is low then ).

My current cass with the GPS anttena.
It's a jelly case. I made a hole on the upper side of the case. Not very ugly, I think.

easy fix
Hey guy's,
Here is an easy fix download GPS status from market touch the menu button and select tools and select manage aGPS settings reset the data and select download restart your phone it worked for me got around 5 satellites in 5 seconds

But any software tweak is useless if you have connection problem... I tired every software, gps.conf file but eventually i ordered a replacement flash cover/gps antenna from ebay about 10$ with tools.

I don't know about u man but that really worked with my dhd

after using the sensation battery inside my desire hd, i'm curious about such mods, but i hope i don't have to use this one, because it's really ugly
but nice, really nice

It's very possible to put the wire inside the antenna cover and get almost the same performance with no external sign of modification.

True. there are different ways of hiding the antenna. You'd only loose maybe 3-8m of accuracy, but it's better then having a wire sticking out.

[Tutorial] Fix looseness from microUSB port

A while ago I noticed that my micro USB cable does not fit well on my U8800 and when I picked up my phone the cable the cable always fall out without doing any force. After reading various sites, to decide what would be the best way and after I did it I'm now leaving here how to solve this problem. In my case it was dust and lint that accumulated because of taking the phone in pocket, etc..
Tutorial
You should use a toothpick, previously buffed with a fine sandpaper like the image below. You can use other objects, but with the toothpick you can do it without turning off the phone because it isn't a electrical conductor and you can also sharpen the tip very easily.

You should clean the area paint in blue below:
After this you should give special attention to areas in microusb port marked in red below which is where bolts fits and attach the cable to the port. You should try to clean as much as possible the dust that has entrenched there.
In my case after 5 minutes of hard work this was the result:
Picture missing!!! A lot of dust!
I used the lamp on my bedside table for a better look inside the door. Those black things are dust that came out of there now do not have any slack in the port works at 100% and I can move the phone without any problem.
How to fix female conector by flipswitch5point
flipswitch5point said:
Tried this, didn't get any dust :/ but what when I was cleaning it I saw the two little holes in the female side of the port that the clips for the male end are supposed to latch in. Turns out my male end was suffering from... impotence? Lol. I took a needle and adjusted the clips on the cable and it holds fine now. Just posting this for anyone else who's suffering looseness not caused by dust.

Thank for the guide, will try it on my old phone.
:cyclops:

Hmm i see not much dust in my Blade port, but it's loose too. Will try this, thx.

Could this be the reason my phone is charging only if I connect the usb cable at a very certain angle (have to use couple of books to arrange this setting)...

Could be, the other reason might be, that your connector is broken at some point.
Try the method above, if it doesn't work i'd contact the support if you still have warranty.

I would suspect that the solder connection from the socket to the PCB is broken.

It could be that your USB cable is bad.

Thanks so much, worked

Thanks my Desire was barely charging now it holds better but still alittle eiffy

really helpful! thanks dude.

alcohol
One thing that helps to is to have a magnifying lens or pocket loop to closely inspect the connector.
It comes in handy if you are "middle age" and the bifocals don't give you a clear enough picture :cyclops:
On my Galaxy note, last spring, I was noticing an unusual problem of it would either "self connect" with
nothing actually connected (it would make the connect-disconnect sound). Upon inspection of the port
on the device, I noticed what appeared to be a greenish-blue substance migrating from the right most
pins, to the middle pins in an arch pattern. After powering down the phone, pulling the battery, I took a
can of dust off, sprayed the connector, then using a lint free cloth, dabbed in alcohol, I wiped down the
entire inside area of the usb port. After cleaning, I hit it again with the canned air for good measure.
After 2-3 minutes, popped the battery back in, and fired it up. Haven't had any more problems since.

THanks for this! i tried it on my OG Evo 4G works like a charm!

I had this problem aswell on my HTC Desire HD
Thanks for telling us about this. My charger stays in now without popping out on its own.

Took a stanley knife to a toothpick and rummaged around in the usb connector of my phone, it feels a little better, so thanks!

I use a sewing needle on my girlfriends phone when the port gets full of lint. I make sure to take the battery out, not sure if its necessary, but better safe than sorry.

If your cable (still) falls out, bite slightly on the plug.
You're welcome.

Lenovo Tab M10 Pogo Pins

Hi,
I have a Tab M10 tablet. It's a fine and cheap tablet that I will use to control my Smart Home system.
I want to mount the tablet on the wall. I wil use some kind of custom built mounting frame for the tablet.
For permanent power, I want to use the Pogo Pins at the bottom if possible. (the same pins are used in smart docks)
Does anyone know if I just can put 5Vdc on the pins and what is the polarity.
Greetings,
Remko
Edit:
Here are some pictures of the dock connectors

No one knows how to use those pins without a docking station?

Hi, I have the same plans as you, same tablet, same purpose..... bought a 2 pin usb cable for smart watch, same dimensions, the tablet seems to know something is happening as it vibrates a little. but then it does not seem to charge :/ If you ever found a solution, i would be happy to hear it. in the meantime, i'll try to have a look, maybe there a security switch that disables the connector if the tablet is not "locked" in the dock though the two holes on the sides of the pin connectors.
Sorry for not having a solution but rather leaving more questions.
link to the cable just in case : https://www.amazon.fr/gp/product/B08SJBK6ZC/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1
Have a nice day
EDIT : It actually does work out of the box, the positioning was wrong (and the pins have to be in the right position, you can't invert the pins so don't forget to try both sides, i got it wrong and the tablet does not seem to suffer from this mistake) as I was trying to hold it in place. So from what I can tell, you should be good to go with this cable or an other (I could hardly find any so i posted a link but feel free to use any as long as the space between the 2 pins is the same as the one in the link )

I am looking for a similar cable for probably a slightly different purpose. I also want to mount it on the wall but at the same time want to use the tablet as Alexa Echo Show. I have not managed to get the Alexa Echo Show mode on my M10 FHD tablet. On enquiring from Lenovo I was told that it works only when it is docked but the tablet did not come with a docking stating.
Are you using Alexa on your tablet? Does echo show works for you when charing using this cable with pogo pins?

TWIMC: If you stumble over an old Pebble Classic SmartWatch charger cable: the pins fit! After removal of the magnets I implemented it into a wooden mini-easel as a stand, used tooth picks for alignment, works nicely! But (BIG BUT) I wanted it to be charging my Lenovo M10 while using OTG - THAT DOES NOT WORK! If you insert the OTG cable, it switches off the Pogo pin charging. Some idiot engineer thought himself clever...
Alternative is looking for OTG adapters being able to charge simutaneously. rare, but available.

Google brought me here. I got a Belkin adapter ( https://www.belkin.com/usb-c-audio-charge-adapter/F7U081btBLK.html ) for this, but that doesn't work either. I had Just realized it had pogo pins so went looking for a solution. It seems this tablet is a real stinker where otg is concerned. It also will not work properly with my external desktop DAC over USB. For my next tablet I will have to do some research beforehand...

Is there any definitive solution to the usb-c port problem?

Guys there is a piece or tutorial that definitively solves the problem of the usb-c port of this device, I like it very much and I didn't want to get rid of it !!

redchilis said:
I've thought of many solutions, however, since my my USB-C port seems fine atm, I'm not fidgeting with it.
1st thing I tried was Wireless Charging.
This video above, gave me some hope, but the youtuber has not shared links to buy what worked for him and none of the high-end Qi Wireless Charging receivers I bought worked for me.
After researching a bit and trying multiple Qi Charging Receivers, I read somewhere, Wireless Charging receivers don't play well with phones that offer any type of fast charging, which our phones do.
2nd thing I tried is getting a magnetic cable, which looks something like the image below

However, the peice that went into the phone has quite a bit of thickness and felt if the phone were to ever fall on the charging port it would break the port and generally, I did not like the aesthetics of it, it was too thick. Check this video out if you are interested in it, it's for a similar phone (Video MP4 file)
3rd thing I considered was to DIY a battery case that would connect to the port and a cover that would be thick enough to cover the port and the battery case. Would then have an alternative charging method, like wireless or USB-C. I gave up on this as my port is fine as of now, since I bought a pre-owned phone, it's been working fine.
Currently, I only use an Amazon basics certified USB-C cable to charge the phone, I do not use the company supplied cable at all.
If you want to change the charging port yourself you can search on youtube you will find a video with reasonable knowledge on how to open up your phone and change the port yourself, like this one
The port itself at the time of writing this post costs 309 INR (maxbhi link)
Hope that helps!

there's none, you can fix it, but eventually, it's gonna broken again. The actual problem is the housing, it's put much pressure on the port so it wears so easily, especially when you're using your phone when charging, which most people often do even just for checking the notification.

In my opinion,
Change the port with the OEM original and replace that goddam USB cable that came with the phone,
That cable is the culprit, I use OnePlus dash cable

I was very luck to find a repair service that fixed the internal piece of hardware (I live in Rio de Janeiro, Brazil).
It took the guy approx. 2 hours to complete the job.
Note that he didn't replace the hardware, but fixed the original faulty component somehow instead.
If you order the OEM component from AliExpress or somewhere else and ask a technician to replace, it would take approx. 30 min.
After the job was done, the back of the phone was glued and kept strapped to the case with ribbons for half an hour.
Also I've bought a new cable, a highly recommended OEM one from Amazon. That was when the first signs of the problem emerged.
Now the fast charge is working again.
In the last few weeks of despair, I was applying pressure to the connector when attached to the port, by rising it or pushing it to the side, which only made things worse, since the internal component was absorbing all that pressure.
Don't do that. If the problem comes, try to replace the internal component asap.
One last piece of advice, don't charge and use the phone. Keep it quiet on a flat surface, like a table or chair.

I read somewhere so not sure of truths but.... the story said the problem was the fit being to loose and causing wear... The solution that the guy came up with was to put a small strip of cello tape carefully around the end of the USB c connector making the fit tighter... Seems like it could be a solution... I personally just keep changing the faulty bit.... The phones in a case so no need to professionally restick the back... Changing the part takes about five minutes

This is what I do after usb port is broken
Spoiler: Picture
You only need cutter blade and electricity solatip
So far it's work and my usb port not loose & broken again.
Hope that help

Hey there! OnePlus dash cable fits perfectly? Any issues so far?

I think there is no solution for this problem. I changed the usb-c board 5 times, the last one yesterday. I finally bought 5 more new, seemingly original boards from an Aliexpress seller, for about $ 16 in total. Here is the link to the article, for anyone interested:
