this is one sad man he was just one week
outside of the three-year warranty period for his monitor when this
happened yeah look at that the panel seems to be fine but there's something
going on in the brains of this little guy that's causing it to power cycle all
day long now he could just go out and buy a new one but that's going to cost
about 300 US Dollars and besides
this one's already broken what's the worst that could happen if we tried to
fix it oh
I mean it's already broken maybe right
here actually
great deals on AMD ryzen processors and AMD Radeon graphics cards are yours for
the taking including amazing game bundles for a limited time from June 5th
to July 1st check them out of the link below tell me what happened uh yeah it
was just power cycling I woke up in the morning it would just do this for a
while it would do the whole logo at first right and then it kept getting
worse and worse and worse I just turn it off unplug it plug it back in hey it
would work I did that for about a week okay so then what you're telling me is
that you're a week out of warranty and you knew about this for a week before
you contacted anyone some of you that actually just
uh yeah cool always consult a doctor as soon as
your symptoms develop friends well one way or another you're out of warranty
now which means we need to fix it ourselves now in a perfect world we'd
get replacement parts directly from the manufacturer but unfortunately ASUS like
many other manufacturers doesn't really stock replacement parts for their older
devices so it's off to eBay
pick click yeah pick click that's great
where we're going to run into another ASUS problem this is super cool the just
the density of these results is amazing yeah don't you hate searching through
eBay and you got to sort through all the parts like yeah it takes forever to find
the thing you actually want a valve index uh clip uh Cable cable
clip I need a cable clip I lost my cable clip for my index genuine OEM valve
index cable clip replacement for back of headset that's the one I need wow the
system works oh it opens in a new tab oh because of course it does because it's a
really well designed web so they know you're going to want to click like five tabs of these things
this is kind of awesome all right anyway Let's uh actually get back to your
monitor but it doesn't save us from that
ASUS problem I mentioned some of their products uh laptops for instance have
part numbers that differ only by the last couple of characters to indicate a
different internal configuration but for the same model of product
for monitors on the other hand we've got results for the vg27aq that's what we
have and also the vg278q1a which is a completely different
product if we bought a replacement board from that one and tried to put it in
here that would not work so even if ASUS
support can't sell you a replacement part I would suggest contacting them for
some guidance to ensure you don't order the wrong thing for our part though we
managed to find this replacement board for really 50 bucks shipped
yeah not bad there's some other ones on here that are like 112 So I think we
actually saved a bit of money yeah that's awesome I mean it's used so who
knows how long it's going to last but personally for that price I'd rather
take my chances than wait the months that ASUS quoted us to get a new part
yeah really it came packed like this yep
used parts I really hope this works
anyway this should be everything we need a main board with low voltage
differential signaling speakers and oh I
guess there's the daughter board for the joystick controller at the front of the
monitor as well so you've got everything there yeah yeah it's basically a full replacement
because I don't know which part exactly in the chain is busted so we just got it
all okay well let's crack open the existing monitor
from the back where there's like no protective anything to hey look at this
this looks kind of like the same size as this okay I couldn't help noticing this
is quite is that is that how this was taped in here yeah
huh that's a monitor for you you know it's a little less impressive when you
look at the inside hey wait no no it's actually like this yeah it's actually
like this we did open it up to take a
look at it and everything so it has been opened before but yes it was
legitimately mounted with tape like this angle yeah
yeah okay because I've opened a fair number of monitors in the past I've
never seen one that was mounted at an angle sometimes they look a little
better than this yeah but it's at an angle for the rest of the case right you
see how these two HDMI ports here
they're at an angle on this side or this side I can't remember but yeah exactly
because we got to replace all these ribbon cables
oh uh oh we only have three second yeah
we only got three ribbon cables well I really oh they're labeled okay so cn1 I
have two two and this is three so hopefully cn4 Works yep I sure hope it
does that that's a lot of ribbons between the main board and the panel I
don't think I've seen that many before 1440p 165hz right yeah it does do HDR
but I'm pretty sure it's just single panel uh you know there's no actual full
array local dimming so I'm not sure why it's got so many ribbon cables are we
even going to bother replacing the joystick in the menu buttons I don't think so it's it's probably fine without
it yeah let's do it you know let's do everything else see if it works if it
doesn't then hey we know what the problem is I see some manufacturing
schmoo on here but there's nothing that's obviously just shorted or popped
or anything like that the new one looks cleaner which is nice I guess but that
also has manufacturing yeah not as much though now this is interesting you're
getting a new revision of the board oh you're getting rev a11 instead of a00
that's a huge upgrade is it
I don't know do we know that this new board works
even uh not yet okay so it could be more
broken than it was to start with you never know
neat we should probably replace this guy too really what does that guy do uh I
don't know maybe probably power supply yeah and you know what if it's power cycling I'm kind of concerned that it's
part of the power supply is the issue okay what's going on here because the DC
in comes in on this board but I don't see anything resembling a power supply
yeah and it doesn't connect uh connect to this guy I mean it's got this cable
here like way over here why don't we do one thing one thing on why don't we figure out what the actual problem was
why don't we just try a new power supply to start okay
so original board dupe you're not gonna short the board
out or anything yeah don't worry about it I mean but it's what it's going to get more dead
okay Power if it breaks at this point
this is on you hold on hold on no no you
were here supervising ah it was your responsibility to stop me yeah but this
was your idea yeah it's uh no it's still flickering okay still power cycling
let's replace Parts one at a time then okay I kind of like the idea of trying
this new power supply here yeah if there's anything that has failed
it's my money is on the power supply
um just because it's a weird power cycling thing it's not like I suddenly
lost you know an input or it just
doesn't do the OSD navigation or anything like that so and if there's
anything that I've learned in all my years doing this it's that if a problem
is unpredictable or uh flaky yeah it's
RAM or power supply yeah and this
doesn't have RAM so ready to try this yeah okay and Power
no still wrecked let me yeah it just
power cycled a couple times yeah all right well it was worth at least
exploring because think about it this way even if we weren't able to buy one
individual part for our repair if we determined that hey it was only the
power supply that was dead you can resell this and maybe recoup
some of our costs well yeah but
yeah off my cost yeah yeah exactly that's what I'm saying and that and I
suspect you could get more than 20 bucks for this just because it's a standalone
part good luck looking for it yeah exactly and it's the main part yes your
board after we've done this if it's still
messed up then maybe it is a cable oh yeah I guess that's true not a loose
connection but maybe one of them is just shorting out for whatever reason yeah
just bad because that's the other thing that often goes wrong if it's not RAM or
power supply we spend like an hour and a half troubleshooting uh busted cable
I can't wait until we make our own cables oh yeah like yeah that's that's
happened to me at least like two or three times on different videos so I
can't imagine how many other times this happened to other people too oops so
that's the new power supply Pro tip
put a little Sharpie Mark oh yeah or just you know put them somewhere
completely different from the space where you're working just mark them yeah
I press the button nothing's happening really
it's not power cycling or anything uh you made it more dead
no that's not possible but it's gonna get more dead did you put the old power
supply in yeah okay look I gotta try stuff at this point
yeah I mean maybe we maybe we had it switched
switch the cables out maybe you broke one of the ribbon cables with all the
finagling as possible it's possible I really don't
think so don't worry very confident right now uh I'm trouble getting that in
there no no no okay highly highly
confident right now he's gonna be like the camera fixing video no
nothing will ever be like that again
yeah luckily we're not trying to bake anything in the oven you must bring up every one of my past
failures who do you think you are my wife
here we go big moment
pretty cool um
we've done a full replace
you guys saw everything okay you know what okay here's what
we're gonna do we're gonna replace literally we're gonna we're gonna go back to the original board for a second
here God hold on hold on we're gonna see if it power Cycles sure because then we
know whether it's the board or something or maybe it's maybe it's the
installation maybe I got some of those funky cables kind of mixed around or
something I'll take this off please tell me it at least power Cycles please
so it's not doing anything are you kidding okay is this plugged in I
checked that earlier that was one of the first things I looked at the squid
should still be on we can change it to a different port if you want it's going
right here no I believe you but like yeah we haven't done anything just
us okay what I don't know I don't
understand I don't either man what is even the purpose of this channel hey you
should DIY repair your stuff don't worry it's really easy oh my God
it's lighting up okay lights up
those old board yeah it's power cycling okay
yeah it's power cycling for sure okay
we're back where we started hell yeah
should we just try it again yeah
oh we got light this time full disclosure we went through a whole thing
with this thing where it seems dead
um we were not getting a light oh I got an OSD input selection wait
really yeah yeah yeah yeah yeah you wanna look
why so we've got the new power supply the new board yep and we're good yeah
it's yeah we should probably plug in HDMI okay to make sure it fully works I
am not letting myself believe that this is actually fixed yet but I know I don't
seem I don't seem very excited right now
100 percent 100 and now what we just
tape this yeah we do yeah this is
bizarre this is where the vase amount goes into it's not screwed on
I gotta put Gap tape over top of that just for some added rigidity
great but Gaff tape is going to do anything you know it takes a gooey tape
probably not but it makes me feel slightly more comfortable
slightly while he's putting that together why don't we talk about one of
the jargony terms that I was throwing around earlier I said this is an lvds
board lvds stands for low voltage differential signaling and it's a
communication standard that's created to help deal with electromagnetic interference or emi emi can degrade the
signal to the point of malfunctioning so this lvds is typically used in computer
buses and video data transfer including
on LCD displays there are a few reasons that it's used over other signaling
standards it provides a more scalable approach to voltage easily adapting to
small Supply voltages while maintaining signal Integrity the voltage compliance
is doubled because it's not limited to a single ended output and the output
current remains constant which simplifies design and reduces overall
cost which as we know is I pretty much
everything is designed to the way that it is that's why we assembled it with
tape
speakers even if they weren't I don't need the speakers all that much oh you
listed it up before I hit it no no you got to put it down when you hit it
yeah yeah okay
he's not stressed look at him you can tell he's not stressed now hold on a
second you already replaced this thing did I just refurbish it so that you can
sell it no I'm not gonna sell it I'm gonna use it I've currently got a little
24 inch 1080p 60 monitor for keyboard streams for monitoring chat and stuff
and um you're going to use
144hz gaming monitor for monitoring chat yeah
I'll put a vertical you know how much you're making everyone's brain hurt right now right why by holding like this
no by using this to monitor chat
you know it's gonna look really good Starving Children could have eaten this game well that's true you know what
maybe at the very least I'll sell the old 1080p 60 that it's going to replace
for basically free I'll give it away to somebody look at that it works does it
yeah are you sure okay plug-in a it does incredible
there you go Jesus we found it incredible at last
they don't have to search anymore I I'm never gonna get tired of that joke
yeah that's pretty good and I'm never gonna get tired of telling you about our
