Missing items on the board

Mon Sep 17, 2018 7:08 pm

Good morning.
When replacing element AP2553W6-7, I blew out the selected elements. Black is probably a 20 kOhm capacitor. The second is probably a capacitor. Do you know the capacity?
I will add that the usb ports do not work.

Look at the datasheet for example circuits. https://www.diodes.com/assets/Datasheets/AP255x.pdf
You will likely have a hard time finding a 20 K Ohm capacitor........
Unless specified otherwise my response is based on the latest and fully updated Raspbian Stretch w/ Desktop OS.

I can replace all of those missing & broken pieces for about £35 or $35.

I definitely can't replace a 20KOhm capacitor without changing the laws of physics.

A 30 pF resistor would probably work! :D
