VCC Core on the PC Motherboard: https:\/\/www.youtube.com\/watch?v=uKybCG1SxyM
\nhow to understand the VCC core from the 12V to the processor
\n0:02
\nassalamualaikum friends
\n0:08
\n, this time we will show
\n0:13
\nsomething on the PC motherboard, what is in front of us is a
\n0:19
\nGigabyte PC motherboard
\n0:24
\n, this time we are not troubleshooting, we will just inform you
\n0:32
\nabout VCC Core,
\n0:36
\nwe often know this on a laptop,
\n0:41
\nhow about a PC
\n0:44
\n, so VCC The core also
\n0:49
\nshows the voltage supply line to the processor,
\n0:55
\nwe can see here some inductors, this is the
\n1:03
\nbridge between the power source from the
\n1:10
\n12V PSU
\n1:13
\nto the processor through the regulator
\n1:22
\nwhose switching is done by this mosfet then
\n1:33
\nthis controller,
\n1:38
\nthis ic controller
\n1:43
\nis Motherbaord H61
\n1:48
\nthe processor is a core i3
\n1:51
\nVGA so one here, the processor is
\n1:57
\nso here there is a VCC Core and here there is a VCC GFx
\n2:01
\nafter 12V enters the mosfet
\n2:13
\nafter the voltage is adjusted, then it enters the inductor filter
\n2:21
\nwhose voltage is further smoothed by these elco.
\n2:26
\nIf on our laptop motherbaord we see more there is an SMD Capacitor
\n2:40
\nthere is a 330 uF, 470uF
\n2:42
\nif here using an Elco
\n2:50
\n560uF with a voltage rating of 6.3V
\n2:57
\nmeans that the voltage that appears here will be below.
\n3:00
\nLikewise, we see the VCC GFx
\n3:05
\nhere, there is a 16V elco,
\n3:10
\nwhich smooths the voltage from the source, 12V
\n3:17
\nas we already know that the elco’s voltage rating must be
\n3:22
\nabove the voltage that will enter
\n3:27
\nbecause the source is 12V so this is enough 16V
\n3:31
\nvoltage then goes into the mosfet, which is controlled by the IC this.
\n3:35
\nThen the voltage needed by the chipset is
\n3:41
\nfiltered using an inductor or the coil is
\n3:46
\nsmoothed again using Elco, as the VCC Core
\n3:51
\nElco functions to stabilize the voltage, reduce the voltage ripple. so later the voltage that goes
\n4:01
\ninto this processor can be smooth. We know that the voltage on this processor fluctuates
\n4:06
\n, so if it’s not soft, the voltage is
\n4:09
\nrough, then the computer must be dumping, bluescreen.
\n4:13
\nproblems caused by problems with the VCC Core are
\n4:21
\nbluescreen or dumping
\n4:27
\nor it could be a warning computer and can’t turn on the
\n4:31
\nblack screen<\/p>\n

\n0:07
\nAssalamualaikum, in this video we will discuss about the PC motherboard
\n0:14
\nwe will show the difference in reading the PC motherboard scheme
\n0:23
\nwith the laptop motherboard
\n0:27
\nbecause we know on a PC some voltage
\n0:32
\nappears from the power supply unit (PSU),
\n0:37
\ndifferent from laptops whose voltage source is one,
\n0:41
\nmeaning the voltage level from the power source. only one
\n0:45
\nof the chargers is only 19V, from the battery it is only 10V
\n0:53
\nbut on the PC
\n1:00
\nfrom the power supply several voltages appear,
\n1:10
\nespecially 5V and 12V,
\n1:15
\nwe can see in the schematic
\n1:20
\nwe see at ATX
\n1:24
\nhere we can see there are several voltage sources
\n1:33
\nfrom the PSU 3.3 V-
\n1:37
\n12V , -5V, + 5V, +12 V
\n1:47
\nso there is 3.3 V there is 5 V
\n1:54
\n12 V
\n1:57
\nthere are three voltages that all appear from the PSU
\n2:03
\nso it’s not on the motherboard
\n2:07
\nso there are some differences in analysis
\n2:12
\nif we are repairing the CPU motherboard
\n2:16
\nthen which we discuss where the
\n2:21
\npowersquence is from the CPU motherboard performance process starts
\n2:33
\nwhat we see here is the schematic of the ACER
\n2:46
\nmotherboard, the ACER motherboard type H61H2 AM3 Version 1. 0
\n2:59
\nbut here we only have a scheme that is almost similar to the LM3 model,
\n3:07
\nno problem,
\n3:12
\nby chance, this scheme has powersquency.In
\n3:17
\nthis scheme, we can see the sequence of voltage emergence
\n3:21
\nand the work process from the start
\n3:25
\nhere we can see shown in numbers
\n3:28
\n1 3 10 this is the sequence of voltage emergence
\n3:33
\nOf course starting from one, what voltage appears the earliest and works the earliest
\n3:44
\non this motherboard. The ECSH61H2 used by ACER
\n3:51
\nis the build-up of ACER
\n3:54
\nACER using the ECS motherboard
\n3:58
\nso the first voltage that appears is
\n4:05
\n1 PS_3VSB
\n4:09
\nso if we are analyzing the motherboard,
\n4:13
\nfor example the motherboard cannot
\n4:15
\nwe turn on according to the
\n4:18
\nvoltage from 1 (PS_3VSB)
\n4:20
\nwe can check here, where does the voltage appear?
\n4:25
\nOf course, from the power supply, where are all the sources from the power supply
\n4:27
\npoints? in this line, to 5VSB,
\n4:36
\nwe can check on the ATX port
\n4:44
\non this port where the voltage appears or not
\n4:50
\non what pin number we see first in the
\n4:54
\n5VSB
\n4:58
\nATX power 5VSB scheme
\n5:48
\nhere there is a 5V AUX code, appears on pin Number 9
\n5:57
\nthis must appear the earliest
\n6:01
\nso if we look at the port,
\n6:09
\nthen we can check the purple cable, the
\n6:14
\nAUX is 5V
\n6:26
\non this cable, the voltage must be 3V or 5V first.
\n6:37
\nIf we look at this scheme, it says 5VSB,
\n6:44
\nof course the appearance of 5 V
\n6:51
\nbut why goes into 3 11
\n6:55
\nmaybe this there is a certain process that can reduce the 5V voltage from the PSU to 3V
\n7:04
\nbefore going to the Super I \/ O IT8775E-EX
\n7:11
\nfor details later, please look for it in the schematic
\n7:16
\nwe don’t discuss there,
\n7:18
\nwe only discuss the sequence
\n7:19
\nso the first thing
\n7:23
\nthat must appear is the
\n7:25
\nvoltage on the purple wire
\n7:30
\nhere the voltage must appear first
\n7:37
\nthen
\n7:41
\nthe second one, so this voltage (No.1) goes to the Super I \/ O
\n7:50
\nIT8775E
\n7:53
\nchipset, which is the small chipset,
\n8:05
\npin what number can we look for a discema
\n8:10
\nthen after entering the I \/ O chips
\n8:12
\nwe are looking for sequence number 2
\n8:18
\nRSMRST_L
\n8:22
\nso from this super I \/ O IC
\n8:26
\nthe code
\n8:29
\nsignal is RSMRST_L,
\n8:32
\nwe have to find this on pin number 43
\n8:36
\nof IC Chips I \/ O
\n8:40
\nfrom this, pin Number 43
\n8:47
\ncomes out the RSMRST code signal
\n8:51
\nmust come out
\n8:55
\nthen the third one
\n8:59
\njust enters This power Button
\n9:05
\nis connected to the I \/ O chipset
\n9:11
\npin number 33
\n9:25
\nso in this scheme we can read at a glance, there are conditions that must be conditionally
\n9:34
\nconditioned first
\n9:41
\nbefore the Power Button button can be turned on
\n9:45
\n, first the voltage on this cable must appear
\n9:51
\nthen on pin number 11 3VSB on the I \/ O chipset
\n9:57
\nwhich is a standard voltage, the voltage is approximately 3 V
\n10:00
\nthen on pin number 43
\n10:05
\nof this chip the
\n10:06
\nvoltage must also appear, the voltage will be sent to the PCH chipset
\n10:13
\nwhere the cooler is
\n10:16
\nsent here the signal
\n10:23
\nthen pin number 33 of these chips must have voltage too
\n10:30
\nthat is before the power button is turned on
\n10:33
\nso first this cable must have a voltage of 5V
\n10:37
\npin number 11 of this chipset
\n10:41
\nthere must be a voltage too
\n10:44
\nthen pin number 43 and
\n10:47
\nthen pin n Number 33 there must be a voltage
\n10:50
\nbefore the power button is pressed,
\n10:53
\nthen everyone, of
\n10:57
\ncourse, next we do is press the power button,
\n11:02
\nhow the power button works
\n11:05
\nfrom this signal, this diagram shows that
\n11:08
\nthere is a downward signal, the box goes down again,
\n11:11
\nthis shows that when the power button is pressed the
\n11:15
\nvoltage is down (drops 0) the
\n11:17
\nvoltage at pin 33 chips I \/ O is 0
\n11:22
\nwhen the power button is pressed
\n11:24
\nbut when it is released it returns to approximately 3V
\n11:31
\nso if at pin number 33 when the power button is pressed the voltage drops 0 then it is released again 0
\n11:40
\nthis indicates the power button it works
\n11:42
\nand the power button has to do with the I \/ O chipset, this is good, it
\n11:46
\nmeans that when the power button is pressed the I \/ O chipset knows that if there is a power button that has been pressed,
\n11:53
\nthis is a command that must be responded to by the I \/ O Chipset
\n11:59
\nso that it
\n12:01
\nworks next how, the sequence is number
\n12:05
\nPWRON 4 in this scheme
\n12:08
\nis the pin number 31 is visible signal
\n12:13
\nSIO’s Power Button down too
\n12:16
\nso after the power button is pressed, pin number 31 must decrease the voltage
\n12:24
\nthis signal is sent to the PCH too (PCH chipset) and
\n12:31
\nso next,
\n12:33
\nso if this motherboard can’t be turned on,
\n12:36
\nit’s pressed it doesn’t respond
\n12:38
\nwe check on pin number 33 of the I \/ O chipset
\n12:42
\nif when the power button is pressed there is no response here,
\n12:48
\nmaybe the connection between the power button and the I \/ O chipset is problematic
\n12:57
\n, we can do this we can do the jumper, of course we will explore in more detail in this scheme,
\n13:02
\nbut if the power button can be detected on the I \/ O chipset
\n13:07
\nbut the laptop does not turn on, of
\n13:08
\ncourse we will Do further checking to step number 4, namely
\n13:13
\npin number 31 of this I \/ O chipset
\n13:16
\nif pin number 31 does not respond
\n13:20
\nwhen the power button is pressed
\n13:21
\neven though pin number 33 responds
\n13:25
\nthen it could be one of the causes is this I \/ O chipset is damaged
\n13:30
\n, friend all of
\n13:34
\nthis is just the beginning we are starting to learn to detect damage to the PC motherboard. We will
\n13:41
\nmeet again in an upcoming video

Analisa VCC Core Yang Hilang (https:\/\/www.youtube.com\/watch?v=wRVCIwauMqo)
\ntrace VCC core from the 12 v source to processor. read the schematic
\n0:00
\nAssalamualaikum warahmatullahi
\n0:02
\nwabarakatuh sobat semuanya yang kita
\n0:05
\nakan ceritakan di sini adalah sebuah
\n0:08
\nkasus black screen yang terjadi pada
\n0:12
\nmotherboard Asus
\n0:14
\nx42d dan ini Teknik ini bisa kita
\n0:17
\nterapkan pada motherboard model apapun
\n0:20
\nya penyebab daripada black screen pada
\n0:23
\nmotherboard ini adalah tidak munculnya
\n0:25
\ntegangan VCC Core yaitu tegangan yang
\n0:28
\nmensuplai prosesor kita biasa sebut vcc
\n0:33
\ncore atau V Core
\n0:35
\nya V Core yang pada motherboard ini e
\n0:39
\ntegangannya melewati coil ini dan
\n0:42
\nini kita sering lihat ada dua coil pada
\n0:46
\nfor Walaupun ada juga yang menggunakan
\n0:49
\nsatu coil kemudian menggunakan filter
\n0:51
\nkapasitor kapasitor SMD ini ini dan ini
\n0:55
\nada juga di
\n0:56
\nbaliknya jadi setelah motherboard dinyala
\n1:00
\nkan kita cek dengan di coil ini enggak
\n1:02
\nada di coil ini juga enggak ada coil ini
\n1:05
\nenggak ada coil ini enggak ada tidak
\n1:07
\nmuncul tegangan jadi tidak tampil apapun
\n1:10
\npada layar monitor baik internal maupun
\n1:13
\neksternal lalu apa yang kita lakukan
\n1:15
\ntentu kita pastikan dulu bahwa jalur
\n1:18
\nvcc core ini tidak short sirkuit caranya
\n1:21
\ngimana caranya tentu prosesor kita Lepas
\n1:24
\ndulu kemudian kita cek resistansi di
\n1:27
\ncoil ini dan coil ini juga tentu pada
\n1:30
\nkondisi normal kalau kita menggunakan
\n1:33
\nmultitester analog tidak bergerak sama
\n1:35
\nsekali ya kalaupun bergerak sangat kecil
\n1:37
\nsekali atau kalaupun bergerak dia balik
\n1:39
\nlagi ke posisi nol karena di sana ada
\n1:42
\nkapasitor kapasitor yang agak gede
\n1:44
\nkemudian kita yakin bahwa jalurnya tidak
\n1:46
\nshort eh maka kita langsung menuju ke IC
\n1:51
\ncontroller yang mengontrol smps daripada
\n1:56
\nblok vcc Core jadi ini adalah IC
\n1:59
\ncontroller
\n2:01
\nvcc core pada motherboard ini dari mana
\n2:04
\nkita bisa tahu tentu dari skema atau
\n2:07
\nkalau sudah hafal biasanya langsung bisa
\n2:09
\ndeteksi ya kalau enggak ada skema kita
\n2:11
\nbisa lihat e data daripada IC modelnya
\n2:16
\nbisa kita lihat di
\n2:17
\nbodinya kita lihat data seet-nya nanti
\n2:19
\nkita bisa tahu IC itu fungsinya apa lalu
\n2:23
\nkita menuju IC titik mana yang paling
\n2:27
\npertama kita cek tentu yang pertama kita
\n2:29
\ncek adalah titik vcc daripada IC ini
\n2:34
\nyaitu PIN yang eh terhubung dengan
\n2:39
\nsumber tegangan yang mensuplai IC ini
\n2:43
\nNah setelah kita cek ternyata Eh pada
\n2:47
\npada PIN vcc ini tidak muncul tegangan
\n2:50
\nvcc ada di PIN nomor 32 yang terhubung
\n2:54
\nlangsung dengan Pin nomor dua kita bisa
\n2:56
\ntahu ini
\n2:57
\ndi data seet pada data seet daripada IC
\n3:01
\nMaxim 17480g ini kita bisa tahu bahwa
\n3:05
\nPIN vcc ada di PIN nomor
\n3:08
\n32 jadi kita cek di PIN nomor 32 ini PIN
\n3:13
\nnomor 32 di sini tidak muncul tegangan
\n3:16
\nlalu dari mana tegangan ini bisa diambil
\n3:20
\nmaksudnya sumber tegangan vcc ini PIN
\n3:24
\nnomor 32 ini dari mana kita bisa lihat
\n3:26
\ndi boot view ini nah PIN ini terhubung
\n3:29
\nke mana saja ya Nah ternyata PIN ini
\n3:31
\nterhubung ke ini ya
\n3:34
\nr8008
\n3:36
\npc806
\n3:37
\npr8021 kita lihat R ini terhubung ke
\n3:40
\nmana kita mulai dari sini nah Ternyata
\n3:44
\nkita tahu bahwa ini terhubung ke + 5 vs
\n3:48
\nkalau tadi yang
\n3:50
\nr1-nya ini terhubung ke vcc core option ini
\n3:53
\nkembali ke IC ya
\n3:55
\njadi kita bisa lihat di sini ada
\n3:57
\ntegangan level tegangan Plus 5 volt
\n4:01
\nkodenya plus 5
\n4:03
\nvs inilah sumber tegangan yang menjadi
\n4:07
\nsupply IC control vcc Core kemudian kita
\n4:10
\ncek di sini kalau di motherboard nya 10 20
\n4:15
\n30 di sini ya di sini PIN nomor 32
\n4:18
\nTernyata kita cek di sini enggak ada
\n4:21
\ntegangan kemudian kita cek pada
\n4:24
\nresistor ini di sini plus 5 vs ini
\n4:29
\nmuncul plus 5 vs ini ada tegangan 5 volt
\n4:33
\nni di PIN satunya ini yang terhubung
\n4:36
\nlangsung ke vcc pada IC control vcc Core
\n4:40
\ntadi tidak muncul tegangan di sini
\n4:43
\nmuncul hanya 0 ohm sekian ini
\n4:46
\nmenunjukkan bahwa ada masalah pada R ini
\n4:48
\nmaka setelah kita cek kemudian kita
\n4:52
\nlepas eh resistor ini kita lepas
\n4:54
\nternyata ada ada apa masalah pada pada
\n4:59
\nmotherboard-nya ya pada apa
\n5:03
\nE di
\n5:06
\npin-pin pada resistor tadi pada resistor
\n5:11
\nini jalur-jalur yang di motherboardnya
\n5:14
\nkelihatan
\n5:16
\nseperti berkerak kayak gosong gitu
\n5:19
\njadi posisinya di sini seperti di f view
\n5:22
\ntadi resistornya ini kecil sekali Nah
\n5:26
\nresistor ini kita cek di titik ini ada t
\n5:30
\n5 volt namun di sini tidak ada maka kita
\n5:34
\nlihat ternyata E solderannya yang
\n5:38
\ndimotherboard itu
\n5:41
\nberkerak maka kita lepas resistornya
\n5:44
\nkemudian kita bersihkan kita solder
\n5:46
\nulang ulang kakinya demikian juga
\n5:48
\nresistor ini kita lepas kita ganti
\n5:51
\nukurannya sesuai dengan eh di tadi dibat
\n5:56
\nview tadi ditunjukkan ukurannya resistor
\n5:59
\nini 2,2 Ohm ya kita kita
\n6:05
\nganti dengan resistor 2,2 Ohm kita
\n6:10
\nsolder dengan baik kemudian kita cek
\n6:12
\nmotherboard ini bisa kembali bekerja
\n6:14
\ndengan dengan baik kemudian kita cek vcc
\n6:17
\ncore nya juga keluar kita cek pakai
\n6:20
\npakai monitor juga normal muncul
\n6:24
\ngambarnya jadi pekerjaan selesai kita
\n6:27
\ncoba simpulkan
\n6:28
\nya J salah satu penyebab motherboard black
\n6:31
\nscreen atau no display bisa dinyalakan
\n6:35
\ntapi pada tampilan enggak muncul apa-apa
\n6:37
\ndan laptop enggak bisa booting tidak ada
\n6:40
\nsuara apa-apa itu salah satunya adalah
\n6:41
\ntidak munculnya vcc Core yaitu tegangan
\n6:45
\nyang mensupplay e prosesor setelah kita
\n6:48
\ncek jalur vcc core ini tidak short maka
\n6:52
\nkita langsung menuju IC controller vcc
\n6:54
\nCore setelah kita cek
\n6:56
\nternyata PIN vcc pada IC VC core
\n7:00
\ncontroler vcc core ini tidak ada
\n7:02
\ntegangannya jadi IC ini tidak
\n7:04
\nmendapatkan tegangan kerja kemudian kita
\n7:08
\ntelusuri akhirnya kita temukan bahwa
\n7:11
\ntegangan suplai IC ini 5 volt dengan
\n7:15
\nkode 5 vs itu tidak muncul gara-gara
\n7:19
\nresistornya rusak kita ganti
\n7:21
\nresistornya beres baik demikian sobat
\n7:23
\nsemuanya semoga
\n7:26
