Thank you for this John, excellent tutorial! I just fixed my wife's tablet, couldn't be happier!
Round of applause for inspiring so many people to save their electronics rather than throwing them in landfills!
The video was very helpful. I'm a DIY guy and a technician by trade. I bought a rework station just to replace the charginging port. Opening the flat cable connectors for the display and the digitizer was a challenge. FYI It made sense to leave the piece of tape on the switch assembly in place. This supports the switch assembly opposite the flat cable once the assembly is pulled free from it's mounting location.. Also I had both speakers come off the board while handling so I had to solder them back on. I came up short on the black lead closest to the power switch and had to splice in an extension. I used 1mm diameter solder which was too thick. Turns out I had some 0.5 in my stash but this was after the fact. Having the proper equipment is a must; a lighted magnifier, the rework station with a pencil tip, solder wick, small diameter solder, a P00 philips head.
These tablets are an older version and I doubt there are many still in use. My son has used his every day for the last 3 years and it still works great! Now the charging port is like new!
Awesome video, easy to follow.
The hint about the "little bit of solder" (not too much) for the pins helped.
Just finished replacing successfully :)
Nice work!
Why look for ASMR videos when I can just watch John repair the tablet.
Excellent tutorial, very well explained ...gave me the confidence to have a go at my own Lenovo . MANY THANKS !!
That's great thank you!
8:07 The 70L model has that small tape as well, but I doubt that's tape, looks more like tape wire, an antenna or something.
Anyway if you can't figure out why the whole board won't come out, even though all screws have been removed, it's because of that thing. Once you remove it, almost immediately it snaps out of its place. It snaps because there are some plastic brackets that also hold it from the other side, but those won't release it until that tape comes out first.
Yes it is definitely not just tape. Some sort of antenna. Seems like we figured out what it is exactly but I've already forgotten. :0
@@FixItPlanet1 it was glued to the inner frame. With a little tug, it comes out.
Overall your guide is a good one.
For the life of me, I couldn't understand what was holding down the board. I wouldn't be able to repair it if it wasn't for your video. Or I would have torn that tape which, who knows what would entail. So for that, you have my thanks.
But you better leave an annotation, or whatever youtube permits these days. Or someone could go, and cut the thing right off.
Yes always beware of hidden dangers. :) Thank you for the feedback. I can at least add a time stamp in the description box and a warning.
hi.thanks for the video.a did fix my charging port with help from this video.greetings from finland,it was pretty easy fix it with help
Excellent tutorial video, Great soldering Technics.
Hi good day, can you please tell me the tools name's and where to get them. The tool you hold the board with, the stripe you use to remove/extract the thin, the small hot air gun, the seringes or whatever you use to pour the alcohol and the flux (seems like a paste), the name of the flux/paste.
Also do you use some kind of magnifying glass for soldering?
My regards, thank you
That little odd piece of tape at 8:05 you didn't know the use of is probably the "warranty void if removed" tape.
lol (actually it is an antenna but that is funny).
I have to replace the USB port too. But how did you manage to open the cable connector at 4:12 without breaking it (mine is now broken at the sides of the little flap and now it cannot be locked anymore)? But the major problem is the socond connector, it cannot be opened at all without totally breaking! Unfortunately I now also have to change this foil cable because just one contact on the foil has gone lost too (I guess I have a very bad day!...).
At 17:15 you add flux, what does this do? Why couldn't you just solder?
Thanks
Flux aids in the flow and bond of solder. It also works to dissolve oxidation.
Hi, I know this a relatively old video to leave a comment on and hope for a reply, but I'll shoot my shot just the same!
The video seems to have no sound or perhaps youtube settings got tweaked, but is it possible to get a second upload site? Or a check through settings to be able to hear what you're working on, and how I can hopefully do the same? I know that your voiceover was critical to other commentors, and I'd love to have the same success!
Thanks!
Unfortunately the back ground music that was license free at the time decided to reverse that and claim copyright. You tube did not allow removal of just the music and required deleting all sound in the affected areas. Sorry
Thank you for sharing this information with us. Very informative. What rough price range to get someone to replace charge port. Yoga a12. I know it depends on a lot of things,, regional, time frame, parts,,, but just a wide ballpark. Thanks again and God bless
Excellent video! Many thanks! I will try it
I noticed you didn't show the struggle of getting the data and power terminals soldered so nicely!
It must have taken a half hour on those microscopic pins alone !
We get better at it as we practice. But yes it can be tough at first. I struggle sometimes even now. Soldering is at least fun tho.
Nobody specifically where I can get that cargo door, probe with some of the other cell phones but they were either very wide or they did not fit well with the piece, I thank them
Why is it so important to take the old solder out of the support holes? Does that really matter apart from doing a "perfect" solder replacement? Surely only they five connectors really need this level of care?
Thanks for tutorial, going to try this!
Removing the solder to unblock the holes and allow the new port to sit evenly on the board before soldering.
@@FixItPlanet1 Super, I don't have that other solder though so hopefully I can clean it out with just the copper braid.
@@pamelajessup7931 You should be able to do that no problem. Good luck!
@@FixItPlanet1 Hahaha, I couldn't get the USB port off using a soldering iron and hairdryer. I need a heat gun indeed!
nice job! Unsure why you had to remove the battery. Just disconnecting it's cable should do the job...
Yes you can just disconnect the battery if you prefer.
GREAT GREAT GREAT Job/Video. Am curious, did you put in a New PowerPort or remove and resolder the Old One?
I'd luv to do this but don't have the cool small solder tools/material you have, so may find it more cost efficient to find a local person in Cincinnati to do it for me. Still, LUV'd the video, Thanks for taking the time and doing a thorough job.
Thank you! Yes a new port was soldered on.
great video what was the heat setting and air flow for the hot air station?
My wife has the same tablet with same problem.I have the tools just not sure on heat settings I timed it took 48 seconds to desolder
Distance, air flow, and temp vary from station to station just have to figure out what works best with what you have to use.
the micro sd card slot is loose because you didnt remove the card before pulling off the rear case, it catches on it and either snaps the card or does what you have there.
Yeah sometimes I screw things up.... Well it's a good thing I can fix it then.. you keep on pointing out the mistakes tho good job!
Awesome
What was the heat level on the air and air setting also the heat temp for solder iron
Temps and airflow vary from machine to machine you just have to figure out what works best with what you have.
Great work. Can you please share what artist is that ambient background music from? 10x
Mine has half the screen dimmer and has streaks running horizontally in landscape mode. Two black lines on the very top and middle. also the broken half turns off if i lower the brightness. any videos on how to fix that? touch screen works fine BTW.
How much would be the max charge for a screen and charge port replacement (money wise)
We had the same problem with the same lenovo Tab Model, we have replaced the charging USB port with no problems. worked fine for one day but now tablet charges only when closed and charges too slow. We have checked USB again for broken pins but seems everything is fine, but issue still remains. I would appreciate your advice. Thank you!!!
You have three main internal properties to consider; Battery, Charge port, and Charging Circuit. The charging cable and block are two external properties to consider.
Double check under a microscope if possible. if any one pin is not fully connected it would do what your describing, however there are other possible causes. Such as high resistance battery, or defective charging/data cable, or incorrect or defective charging block, just to name a few examples.
Thank you for your advice
Hi sr thank you,my tablet has this problem i can't hear it loud.should i replace the speakers
Maybe give it a try.
Amigo yo tengo una pregunta el displey de la table lenovo tab2 A7 10f es conpatible con la lenovo tab2 A7 20f

Nice thorough/detailed repair. Where are you located? I've got a Lenovo 1st gen Tablet I'd like to get repaired. It also has a charging port that needs to be replaced. I'd like to contact you and get an estimate, if possible??
Nice talking to you Doug talk again soon thanks!
Hello can someone explain what he used to disolder the old and resolder the new usb port? He said something about an alloy but i cant understand , he keeps saying it under his breath.
The alloy is a low melt alloy you can see here amzn.to/2VMrLki Solder wick to wick up the solder here amzn.to/331rqvL
is there a list anywhere of what tools I'd need to do this?
iFixit.com has plenty of tools to get you started
is there a video for a busted screen? mine still works perfect but glass is a mess.
I haven't made a video on on that repair for this tablet yet but someone probably has on RUclips somewhere. ;)
I cannot get the back off, I tried with a plectrum but it wouldn't budge so I actually brought a professional tool kit and tried but I still couldn't get the back off and ended up breaking the screen, how is it done ???
That process is shown at the beginning of this video. It is not difficult. A thin pick is inserted between the frame and the back cover and slides around the tablet pulling the back off as you go.
hello, I have lenovo tab 3 7 and it suddenly turned off in enough battery, now it only vibrates on pressing power switch.
I have tried disconnecting the battery and reconnect it, but it didn't work. Also I have tried your method, but it won't start. Plz help. I hope you'll reply to my problem soon. Thank you!
I have a lenovo a3300gv which is dead bc of wrong firmware flashing. I think it's in dead bot stage now. Could you plz help me out with it?
Try this link firmwarefile.com/lenovo-a3300gv Maybe that will help but idonno Looks like you've seen this vid here ruclips.net/video/r_RESyLw6rc/видео.html Good luck!
Can some One say me how to buy a usb charge port for this lenovo
omg how much to fix my charge port? I don't think I have the patience for that.
Fix It Planet thanks I will bring it by asap I'm in lake Worth so luckily a short drive.
Odd one, The magnets that are in these, not speaker. Where are they, need to remove them as wife has pacemaker.
There are no magnets in this tablet (that I recall) other than the speakers which are very low strength. Unless she put them right against her chest I don't think they are strong enough to have any effect on a pacemaker, however I'm not an expert on that sort of thing so you should check with her doctor and verify safety concerns.
Cheers for that.
Where did you get your vice?
