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 circuit tell me which coil I can use? I have many broken screens, but none are the same.
2. I can't find the exact Richtek chip. Someone once published a list of all the ones in that format... but I can't find it. I think the reference PD=6J was enough; the rest, I think, was the manufacturing date.
I'm attaching photos of everything.
Thank you!!!
