My Sparkle (SPI) PC power supply has broken. Originally, there was totally no power output. The 5V-standby was not there. I have replaced a few bulged capacitors but not helping.
I was trying to do more troubleshooting but burned more components. Some got burned so badly that the markings were gone. And also, the markings of a few transistors were gone because the component surface was worn out somehow.
If you happened to have disassembled the same PSU model, please help to provide the markings of some of these components.
Can you please help me identify these components from the motherboard. I saw a similar topic, but it was for HP840 G4 (https://www.badcaps.net/forum/troubl...arging-problem) Are those described there the same components?
In the first picture, I have circled in red the burned components. It was due to short switching positive with negative. Probably the motherboard will not work, but I can try to repair it. It is a laptop for experiments,...
Hi, I received a Liquid Damaged Asus UX7602Z for repair. I've cleaned the motherboard and found couple of damaged components. Two of them (near the battery connector) I can't identify. One is a resistor of unknow value, and the other one is probably a transistor. Laptop won't charge the battery without them. Please see the pictures and help with components identifying. I couldn't find any schematics or boardview for this laptop.
Laptop model: Asus UX7602Z
Motherboard: UX7602ZM, R2.1
Good evening, can you help me with a complicated repair?
I'm repairing an LED screen gaming notebook. The screen has a short circuit, and when the notebook is plugged in, it won't turn on. I found the short by removing the coil in the red circle, and by injecting voltage, I see that the Richtek power supply in the blue circle is heating up. Therefore, I have located the fault.
But I have two problems:
1. The most serious is that I accidentally lost the coil, and I don't have a photo. I can also tell you that there was nothing written on it. Can anyone who has seen that...
I am trying to identify what are these components?
#1 seems to be an inductor, but I get not reading when measuring it. #2 also seems to be an inductor and again no reading when I measure it. You can see a smaller inductor above #2 that has cracked and open.
Any help in identifying these 2 components would be welcome. I am pretty sure #2 is an inductor, but #1 shape is odd, and I am not sure. I also show a microscope view of each component.
