Hello guys! Edgar here
with another video so we can learn something new today
today someone sends us this box that has
many phones
by the way, if you live in Guatemala and want to repair your device
I'll leave in the description a WhatsApp number
only to receive work
this number is only for people who lives in Guatemala
otherwise you'll get no answer
it's only if someone wants to get their device repaired
we are located in Esquipulas Chiquimula
for the moment, at the time I'm recording this video, we're here
probably in six months we will be back in the USA
because we have our main location
but for the moment we're in Guatemala and we're repairing here
this client called... well I'll not say names because sometimes they don't like it
XS MAX, display turned off, but the phone is still working, we receive calls but it's not image... nice
ok, they also send us an XS of Face ID and a 6S Plus that turned off and no longer turned on
we have 3 devices here
let's start then, I've already repaired Face ID
let's start with one that will probably be easy, let's start with the 6S Plus
subscribe to my channel if you haven't, I've seen that
78% -80% of the people who watch my videos are not subscribed, what's wrong?
here, subscribe
ok then, let's work with these phones from the start
because I've just opened this box, that's good because
if we find a mess this will be good for everyone
I'm just adjusting something in the camera so it doesn't bother you
ready, then, let's disassemble this phone
let's ask for our dearest editor to put this in fast motion and play some nice music
no no no, not rock this time, play other music
ok, that's good
Ok, always that we're going to work
give me a moment, I forgot to open the software of Power Z
ok, here's the Power Z software and also the software for the multimeter so we can measure
this will probably be an easy problem, but we'll find out
Whoops it says the multimeter cannot be connected, what's happening?
for some reason I cannot connect my multimeter, if I don't have one problem I have another
but something always has to go wrong
in my pretty videos, but whatever
let's do all we can to make this work
As I told you, whenever we're going to work, we always have to
let's set out Power Supply in 4 volts 5 amps, ok?
we cannot start working without knowing the consumption of the phone
now I'll turn off my Power Supply
but I'm going to connect it, whenever you have a phone, you have to check the consumption
let's check, I turned it on, and if you notice in the blue digits from here
we don't have a consumption, now, if I turn it on it goes to
140 amps and it stays there
this sounds familiar, and I know that you should be bored about this kind of repair
I'm going to make sure this is what I'm thinking
please, always in your diagnose protocol, you must have "realize a test with SMB"
trust me, these tests will help you to know if your Tristar or Hydra are working
Why? Because you must remember that a phone with damaged Tristar can cause the phone not to turn on
Put your Power Supply in 4 volts and
3 amps. 4 volts 3 amps
now, this is ready
and now put
this
positive and negative
Power Supply with 4 volts 3 amps
mA, ready
now I'll join these two positive together, and let's see if it's alright
Pin #1
Pin #1 consumes
Pin# 2 consumes, Pin #3 consumes, Pin #4 not consumes, Pin #5--
this is Tristar, ok?
just like that, you can get an income of $50 - $70
look how nice is this work
let's do this repair in fast motion, and I didn't have it contemplated, but let's do another repair here
to make this video worthwhile
so, let's do this repair in fast motion, I'm just going to replace a Tristar
so... at the count of 1...2...3!
Ok, now as you can see, this phone can turn on again, everything fine
I just have to charge it and that's it
now, this is a pretty common repair, this is a 6S Plus model
and yet in 2021 we still have that model
Now, how much I charge for it?
the charge to a store, because this phone is from a store, I charge about 350 GTQ, about 46 bucks
almost 50 bucks to a store
this store could easily charge about 500 GTQ, probably, I don't know
about 70 bucks
I know the value of this phone is not much, about $100 to say the least
but there is still place to work
Imagine we charge less for it, I don't know... $35/$40 for this repair to a shop
It's something that took me ... I've been recording for 20 minutes
without recording, that repair takes me 10 or 15 minutes
it is something very well paid, it does not matter if it is already an old model
What I want you to understand with this is, protocols, the importance of protocols
I didn't make anything up, this is something that I say a lot, please, we have to learn this well
with this phone you could probably make many mistakes
but we always rely on two very important things when a phone does not power on
First, check the consumption
the phone stays fixed on one consumption, then we have to discard certain things such as Tristar
you can discard Tristar easily with SMB
I'll leave you a link, I don't know where, but I'll leave you the link so you can make your own SMB
with less than $10 you can make your own SMB
or if you don't want to make it, you can buy the Docktest from Servicell Arauca, it's the same
we just have to measure the current in the Tristar, that's all, that can tell us if the Tristar is damaged
if we go to the computer, we can see that this Tristar is the U4500
this Tristar U4500
is controlled by I2C
now, if this I2C is damaged, or the circuit that controls the I2C is damaged
that's why we have a phone with a fixed comsumption that just doesn't turn on
because it is controlled by very important data lines
and Tristar is between the circuits that MUST work
for a phone to turn on
"Edgar, you're going to repair another one?"
No, we're going to leave it for a next video
because I want you to subscribe and keep learning about this pretty job
in a very simple way
so guys, this was a simple video, but we have to learn not to replace the Tristar, that's easy
but always the steps, the steps are very important
to avoid making mistakes
So, it was a pleasure to greet you all, take care and we'll see you
in the next video
Bye!
