Hello
I need help identifying the marked capacitors. I do not have a schematic or board view for this motherboard. Is there any way to identify these capacitors?

Solution
There are 3 ways to possible identify the capacitance.
  • Get - buy the service/repair manual from manufacturer.
  • Use soldering station to remove the capacitors - then you can use a capacitance meter to measure their value. The risk here is that overheating may be an issue if you're not familiar with soldering.
  • Draw up the schematic yourself - you need to draw only the part that involves the nearest components. The issue here is that when you meet a transistor or IC, you don't know for sure what terminal function is (because that is described in service manual) and may have a huge impact on measurement. When you have an idea on how the capacitors are connected internally, you can measure and you should have an idea on what...
