Hello everyone Today, I just fixed a Benley stove I think this stove is quite beautiful, so I will make a video about it This video will help you find out more about stoves This stove only has a hole in the control panel The power panel is not a problem Benley I think this panel is very basic A lot of stoves use this kind of panel First, I will make a hole in the power supply panel I will make holes in the power supply panel so that you can find out more about stoves First, I will make a hole in the power supply panel This is the power supply IC This is the power adapter This is the DC 300V power supply The power from the DC 300V power supply goes through this power supply It will convert to 18V and 9.5V Then the 9.5V power supply goes through this 7805 power supply To reduce 5V for the control The 18V power supply goes directly from this power supply It will be supplied to the driver IC It will be supplied to the cooler fan The cooler fan in the stove always runs at 18V This is the power supply IC The name of this power supply IC is Viper 12A You can replace it with Viper 2A or AP8012 When we look at the power circuit, we can see that the 5,6,7,8 pins are connected to each other That is the pin D of the Moffet The 1,2 pins are also connected to each other That is the pin S of the Moffet The 4 pins are the VCC power supply for the IC The 3 pins are the FB power supply for the DZ18V The 5,6,7,8 pins are connected to each other The 1,2 pins are connected to each other When we look at the power circuit, we can see that there is a diode A 1-in-2 capacitor And a 100K resistor I understand that this is related to the voltage drop That is why this power circuit is a 1-in-1 circuit Of a VCR that I have analyzed The 1-in-1 power circuit has 3 components A 100K resistor A 1-in-2 capacitor And a diode We can see that there is a diode on the main power circuit If it is a 2-in-1 power circuit, it will not have a diode But on the Benley circuit, there is a diode A resistor, a capacitor, and a diode If you want to refer to the video where I analyze this circuit You can see it in the suggestion card at the bottom right If you want to refer to the video where I analyze this circuit You can see it in the suggestion card at the bottom right Now I will look at the power supply first It is this capacitor I will pull out the power cord First, the AC220 voltage will start at these 2 poles Low L and high L Then a wire will go through a pin This wire will go through a pin Then there will be a resistor I will talk about the power supply later And another wire will not go through There will be 2 D1 and D2 diodes To adjust the DC voltage for the power supply This is one This is another I put it upside down One Two They are connected It will be D4 and D5 It is equivalent to D1 and D2 on this circuit It connects here Then I will look again At this position It is the junction of 2 diodes This is one It will go through another diode Equivalent to D3 It goes through another diode Then it goes through the resistor The resistor on the circuit is 2A But on this circuit it is 51A Green, green, brown, black, silver It is 51A It is the resistor of 2A I put it through It goes through Then it is filtered by a DC 300V filter It is a 4.7mm filter It is also a 4.7mm 400V filter This is one From the power supply here It will have a DC 300V power supply We pay attention to this We just saw the half-circuit path Its negative is It will have 2 more diodes In the main rectifier To go back It must have 4 diodes 1, 2, 3, 4 diodes It will create a DC 300V power supply here Guys I will continue to show you From the power supply at the center of the circuit It will go to the pin-up Here The pin-up It will go to the resistor It goes to the resistor Here I will turn it up This is the pin-up This is the main rectifier It will go from here Go here On this pin-up It will have 3 components I will show you It will include A 100 ohm resistor A 1.2V power supply A 100 ohm resistor A 1.2V power supply Here A 100 ohm resistor A 1.2V power supply A 100 ohm resistor A 1.2V power supply It will go to the pin-up It is a bit upside down It is different from the circuit I drew The diode is upside down The resistor is upside down But the 3 components are the same It will go here It will go to pin 5,6,7,8 I will call to display New 9.5V I go to 7805 in My 7805 in is 3. And this is 3. This is 3V 3. The main board is 5V 3. Dadadgda This is the circuit The 1k voltage may not be correct It is at the tip of the skin It will go along this line It will go to this pin This is the VCC pin of ICMSU Next, the 5V line It will go to pin 2 The pin 1 is GND The pin 2 is 5V This is the 5V power supply for the face On the face, there is an IC TM1628 It also needs a power supply This IC is used to control the LEDs and receive the pins This is the IC TM1628 In this IC, there is no program It's just an IC that controls the LEDs and receive the pins This is TM1628 This is the 5V and GND power supply for the IC I have finished the power supply Next, I will show you the 18V power supply for the driver Because many people don't know this circuit This is the 18V power supply It's here It's at the top of the 18V DZ It will go to the fan It will go to the fan pin It will go to pin C of 8050 This is the power supply for the fan If pin B has a high voltage, it will go to pin E This is pin E When we turn on the fan, it will have a high voltage It will go from pin C to pin E It's the same as 18V Next, I will show you the power supply for the 18V driver I will show you the power supply for the 18V driver Here 18V Zoom in This is 18V It will go along this line Go to here Usually media kitchens will go through a 120 ohm resistor But this kitchen does not Go to here It goes through the D11 This is 18V It will go through the diode 4148 This is 4148 It will supply 18V to this side This is 18V It will go through the diode To here And it will go to this cabinet This is the cabinet It is big This is the cabinet that supplies 18V To the driver It usually has 3 transistors 1, 2, 3 But this one has 4 There is another one This is the driver It will go through the diode And it will go to here We can see To here These are 2 resistors 8050 and 8550 2 transistors To supply 18V Look at the diagram These are 2 resistors I want you to know these 2 resistors Because when we test 18V We usually check these 2 resistors 8050 This is the diode This is 8050 These are 3 resistors We can see Q18050 And 8550 Above 8550 These are 2 resistors To supply 18V To here These are 2 resistors To supply 18V To here I want you to know These 2 resistors 8050 and 8550 Because when we test 18V We usually check these 2 resistors Q18050 And 8550 These are 3 resistors To supply 18V To here Q18050 And 8550 These are 3 resistors To supply 18V To here 300V power supply For the power supply Some of you may want to know The power supply is like this First is 2 wires The DC 300V power supply For the power supply It is completely different from DC 300V For the power supply It goes through these 2 diodes It is combined with 2 diodes Inside the main rectifier It creates DC 300V Now The DC 300V power supply For the power supply It goes from AC 220 To these 2 diodes Low and high 1 wire It will go Directly to 1 pin of the main rectifier And 1 more pin It goes through the diode 10A And 1 more pin These are 2 pins of the main rectifier As I draw There will be a 220 It will go through the diode 10A This is 220 Let's put it back We will see These are 2 pins It goes through the diode 10A It goes through the main rectifier Let me take a look at the main rectifier The bridge is like this It is inside It is like this These are 2 AC pins It will go through the diode 10A And 1 more pin It will go through the diode 10A There will be 4 diodes In the main rectifier It will go through the AC 220 To DC 300V It will go through the diode 10A And 1 more pin It goes through the diode 10A It is connected to the magnet of a Tsunami And it will go through an R-SUN power supply to the E pin of the IGBT The power supply on the R-SUN power supply will go this way to protect the wire I will check it later It will go through an L-SUN power supply to the E pin of the IGBT Then it will go through an I-SUN power supply to the E pin of the Tsunami And it will go through an I-SUN power supply to the IGBT Then it will go through an I-SUN power supply to the E pin of the Tsunami I have removed the E pin of the Tsunami It will go through 2 I-SUN power supplies As you can see on the screen, it will have 2 I-SUN power supplies It will have a 0.33uF capacitor It will go to the C pin of the IGBT And it will wait for the trigger to open at the G pin, it will close from C to E to return to the MAS This is the R-SUN port When it goes to E, it will go through another R-SUN port to return to the MAS This is the position 2, which is the same as the position 1 of the diode So I have finished drawing the power supply Next, I will draw the wire protection circuit, because this circuit often has errors I will talk to you about the error of the power supply When there is a term that we plug in and it does not go to the power supply And then we check that the 10A pin does not burn Then we will plug in and measure to see if the 18V and 5V power supply have If it does not have, then the power supply is broken I often see that the power supply is broken because it hits the 12A IC It hits the 12A IC, hits the SDS, hits the SDS Then it will burn this pin On the circuit, it is the 51 ohm resistor Some circuits are only 22 ohm, but on the circuit I am drawing, it is 51 ohm When there is a term that we plug in and it does not go to the power supply And then we check that the 10A pin does not burn Then we will measure the SDS to see if it hits the 12A IC If it hits the 12A IC, then we will replace it with another IC If it does not hit the 12A IC, then we do not need to replace the circuit, but we need to check if the power supply is broken Because sometimes this power supply is broken at the bottom If it does not hit the 12A IC, then we will replace it with another IC I have a lot of videos on how to replace the power supply
