Hello every dear member !

I have a situation with an iphone charger ne diode has been died and 2 or 3 resistors were heated up and left black grime nearby them ,i created some photo's (i disassmebled very carefully the charger and i have to admit i made a very good work ) where you can see the disassembled charger and a schematic.The blue circled is a diode ,Does anyone know is it an 1N4148 or a1N914 ?If anyone can help me to identify these 3 resisitor's(circled red) value i'll be very thankful

 

The problem is that the schematic does not relate to the board with the problem.

 

If it helps the 1N914 and 1N4148 are interchangeable. Fairchild uses the same datasheet for both of them.

 

What blue circle, which photo?

The chip is an L6565 green chopper.

 

Sorry i uploaded wrong picture

 

The diode can be any type like 1N4148, you're going to have to take sharper close up pics for the resistors....

 

So i soldered the right type diode?i will upload photos form it

 

there's the closer picture

 

Can anyone help me based on the picture above?

 

I fear the answer is going to be no if the numbers on the resistors are not readable.

 

Can anyone help me based on the picture above?

Yes click on the Full Circuit Diagram!! i posted in post#4, the resistors R3,R14 are 4.3 ohms Source current monitor for the mosfet.

 

I fear the answer is going to be no if the numbers on the resistors are not readable.

Sorry, I forgot we had a schematic.

 

Someone can tell me the value of this resistor? i calculated on the google with color code calculator but it's not obvious ,maybe it's 940 ohm ,the colors is: red ,black ,black ,gold ,white /but there's no white in the fifth band menu.It's near the 220v plug so it must be high ohm resistor.I think that's the last bad part.I appreciate any help

 

Red-Black-Black is 20 ohms. Gold is only used to indicate tolerance so the first digit of the value is the red one at the opposite end.

Is it R30/31 on the circuit diagram?, or it maybe an inductor 20uH 5% ...

 

It's KB1 on the diagram.The resistor ha a fifth value the white stripe!.So it's color code is: red,black,black,gold,white

 

KB1? Is that the schematic or the PCB silkscreen? I had a good long look at the schematic and could not find it.

I'm looking at the schematic to which Dodgydave linked:

the PCB silkscreen

 

That ID does not exist on the schematic as far as I can see. Can you identify one or more components to which it connects?

By the way, did you try measuring that resistor?

 

Thank you for xyour help ,i can't measure it because it's totally blowed up ,the multimeter not show anything,there's a photo from it in my previous reply ,you can see it has 5 stripes ,and i tried many colour code calculator and no one can identify it .
