Many thanks for this, had some extra Noctua thermal paste and decided to replace the stock paste (Which was just cheap pink goop) A good bit snappier after the boot up.
your welcome
Hey did you remove the pink pad there ? Can I just remove it and put a thermal pad instead ?
Thanks for the informational video i did this to clean my camera lens... Turns out it had a lil spec of dust that it always focuses on.. Thanks dude
Your welcome, glad I was able to help!
thanks for the video im in love even more with this phone. on how easy it is to change components out.
No Problem :)
Very fine video. However, you do not have to remove the small camera to remove the motherboard, unplugging it is enough. It is also held in place by some sticky which was not the case in your video. Also, yes. Use alcohol to remove the pink dried thermal paste and replace it with a small drop of some new before reassembling. As another poster mentioned, it may speed up your phone!
Your video was really helpful, thanks a lot👍
You're welcome, glad it was of help.
I love these phones and this is a great video but why has he not followed his own instruction or should I say your own instruction and remove the battery yet
Thanks for your help, nice video, I just want to know, which v20 version is? H990?
after replacing the middle assembly with the speaker and fingerprint reader, I no longer have reception. I checked all the pins that touch the antennas and even tried bending them up a bit and still nothing, any suggestions?
can i ask you where the antennas are located? is there an antenna port? please help
same problem.. you know what is solution?
Same thing happened to me just yesterday. Nobody ever figured it out?
When the speaker is on, no sound is transmitted to the other party. What's the reason?
Might be a bad headphone jack that is thinking something is plugged in when its not, or a bad secondary mic.
If I have a broken phone with the lower section of the mobo broken, how do I get the memory off this broken phone and put on a new phone?
i have a microphone problem on my V20 F800S which to be exact, when i do video calling via whatsapp or normal call with loudspeaker mode on.. the other party only hear a dead silence from me, even if i shouting out loud at the phone.. should i replace the secondary mic which is obviously near the earpiece or the third mic which is soldered at the motherboard?
please don't be a third mic, i'll be doomed if the third mic broken because i can't back to micro-soldering anymore..
I'm not too sure which mic would be having the issue or if the mic is the problem. Have you cleaned out the holes for the mics on the phone first to make sure they are not clogged? Second check the headphone jack, maybe something is wrong with the headphone jack and it thinks a headphone is plugged in when it is not.
Where should I apply thermal paste?
See the pink dot between the motherboard and the screen? That's where it should be placed.
mubd1234 do i have to spread the thermal paste to cover the whole copper area? I'm completely noob.
por acaso tem o manual de reparo do lg v20 h910 ?
I just replaced my screen and painstakingly moved every small component over to the new assembly. Was that necessary or did I only have to move the headphone jack, ear speaker, and camera?
Well everything is there for a reason so you would actually need to move everything over. The gaskets/contacts/covers etc. Gaskets if any would prevent extra light hitting the light sensor to turn screen off n on when its to your cheek, or prevent excess noise coming to mic. Those contact points and everything else would be needed to make whatever they are going for work and receive power. Unless your replacement comes with all those, best bet is to move them over to the new one :)
It's it possible to remove the button from the back part that comes off with the camera glass?
I dont know what you mean, please explain
Can you pls create a tutorial for replacing the thermal paste on V20?
Hi, just follow this video to take it apart, and you can just take off the old thermal pad (circle pink looking thing) and replace it. I don't think these used thermal paste from what I can remember. So you would need a thermal pad instead.
Thanks a lot
@@athrunskye There is thermal paste on the pink part. Some people replace it with either a .3 or .5 mm thermal pad but most use paste. Thermal paste is better at heat transfer than a pad, but some people like to use the pad in this situation to fill a supposed minor gap between the two surfaces that paste does not generally fill.
Any body know the function of the two small contacts that are located on the top left (can see @ 4:09 on video)? There is gray tape attached to it that runs through the top on the frame. It has P4 and VZW labeled on it. My new assembly did not have one pre-installed and I teared the old one when moving it.
are you referring to the gold contacts? It would probably be the antenna lines for reception/service. The one that says VZW would be the Verizon antenna line. I would believe if your missing that, your reception would be poor or not give you reception at all.
were you able to find that part, because i broke that flex cable to.
Which varient is this? Is it the f800k or the H990N?
It was such a long time ago, I don't remember at the moment. I believe it was the international variant but I could be wrong
is this having bootloops?
Two years late, but yeah. Mines been suffering from bootloop, which is why i'm here, sadly.. smh
some of the v20's are having issues with the audio on the loudspeaker /lower speaker.(ie,sounds distorted or blown)
could you look and see where the amp is located and where connection routings are for that speaker?
my v20 lasted 12days since activation.
thanks for any help you could give.
Hi we don't have any v20's at the moment for me to look at but have you tried downloading third party equalizers to mess around with settings see if it might be a software issue they might fix in future?
yes i had tried aftermarket eq app's but they didn't make the slightest difference.
i first suspected there were problems with the amp when i noticed static noise coming from the phone you could actually here the amp switch on and off almost sounded like a cold solder joint or bad connection.
i'm looking for an v20 with a bad esn or broken lcd for testing ,i was hoping someone had already started looking into this problem.
thanks for the reply.
Oh I see, sounds good keep us informed if you find out.
If my v20 doesn’t want to turn on would there be a way to remove the memory from my old one and put it on a new v20??
Hi, if you have it stored on your removable sd card then yes but if its on the internal phone memory then you would not be able to.
@@PBKreviews Why not? Is it not possible to solder off and replace the memory with old one?
@@philindeblanc Its possible, but you would need to have professional solder skills and the right tools for doing it. Most people can't. Very few people would be able to do it.
Please sir i need help, what specific type of screws are they as i am in need of some?
They are philips screws, but not sure the sizes etc nor where you would find replacements.
Hey, is the glass lens cover on the plastic frame removable? I hear it's quite prone to shattering and I would like to know whether it could be easily replaceable
Yea its replaceable/removable but its not too easy to do either. Its held on with adhesive.
pwrdbykyank By not easy do you mean it has to be heated to soften it? Could you describe for me the steps, I'd really appreciate it, thanks!
Yea needs to be heated and pried off.
pwrdbykyank Ahh ok seems doable, thanks man
no problem
Whenever I'm in a call and I activate speakerphone my microphone becomes muted. However the microphone picks up my voice when I'm speaking into the phone regularly (ear to the phone) and even when I'm recording audio. I've done plenty of factory resets to know its not a software issue. What part would I need to replace to possibly fix the issue?
There are different mics around the phone which activate for different times. Check and make sure the small holes around the phone are not clogged causing sound not to enter. The speaker mics usually are located on back or top rim of the phone. Should be a small dot/hole.
pwrdbykyank thanks that helped me big time
Glad I was able to help :)
can u tell me where the antenna port is...i have googled n cant find it.
well the top and bottom plastic pieces have antenna lines drawn in them (if im not mistaken) and they touch the contacts on the top and bottom of the board.
pwrdbykyank
thank you
Does anyone know what the silver strips on either side of the LG V20 are for? They run up both sides and end at the top in green tabs. On mine one of the tabs is sticking out and could get caught. I was hoping to find out here but they were not mentioned.
I don't know what silver strips you are referring to
Actually they are black not silver and end in a green tab at the top.
I still have no clue which part your referring to. If you could get a pic or something would be great
Awesome video. Thank you! I subscribed! ;) I hope you know the answer. My v20 has that screen flicker / jitter when watching any video or photo, locally or on UA-cam. Even Google play is doing it now. With older models people have reported exactly the same issue, and people say to remove the back cover, then to loosen the camera and screen ribbon cable from the motherboard (like you did) and reconnect then, to fix. Ever heard of this issue / solution? Cheers! ;)
Hi, this is the first I'm hearing of this myself, but I wouldn't jump to a hardware issue right away. First try restarting the phone in safe mode and see if it still does that. It kind of sounds like a software firmware issue to me. It might also be some apps you have on your phone causing issues. If safe mode doesn't fix it, try backing up your stuff and do a factory reset on the phone and see if that fixes it. If it does then you will know some apps or firmware issue was causing that. If that still doesn't then look into taking it apart and putting it back together. I'm thinking some apps might be causing ram to run low or processor to overheat causing some issues. Let me know what happens.
Thank you
thanks, nice video....;)
why do you have water damage
I don't have water damage. Its red underneath the water damage indicator sticker so when water touched the clean top side, the red bleeds through when activated. :)
Forgot to mention the mic
now why can't everybody else make phones like this? wish this phone had wireless charging and water resistance though, and i would have been just fine with a plastic peel off back like the old samsungs. kyocera seems the only company that still makes no-nonsense phones designed for function rather than fashion ... unfortunately the specs on those Kyocera phones are from 3 years ago, so you might a well just buy a used Note 4 instead.

Hi all, any one know where gps antenna v20 located ? My v20 unable receive gps signal correctly. Thanks
I'm Not sure but I think if you look at the aluminum battery cover on inside around camera opening you will see an antenna adhered to it. It has gold contacts which touch contacts on the board to give signal. You can try looking at that to see if it has any issue. You can see this at 0:33 in the video on the right
I have this same issue. Did you find a fix?
Mitch White not yet
pwrdbykyank i already try to pull it so can contact aluminium back cover. But still not work
If you bought the phone refurbished or from a sketchy seller, they could have put the wrong parts to the wrong phone. Hope this helps. www.reddit.com/r/lgv20/comments/7fx2gz/becareful_buying_the_top_plastic_bezel_of_the_v20/?
Note: if the 21 screws aren't in place, the phone will not start. (At least not in my case)
it's so strange when a single phone I was ready to pay $700 now after opening it seems what the..... don't want to spent even 100...... quantative mind!!
stallio the v20? id never pay 700 either lol. its still one of the best phones on the market. it has the best video so far from any phone ever made and im glad the screen is easily replaceable my screen finally got a small crack after falling face first like 10 times but it still worked great after!! i got it for 400 but def best phone of its time
kind aweird I thought v20 had heatsink
You need better lighting, and using a dark brown background is not good either.
Also your PBK logo in the lower left of the screen is way too large.
I'm just trying to offer some helpful feedback.

Thanks for the feedback, I did use lighter backgrounds before but would cause the camera not to focus as well. The more light I used the less control I had with the focus for some reason. Also the logo I make large because I've had people crop out the video before and use as their own lol.
problem imei lg v20
sir how to repair Speaker thats my problem sir :(
