Have a nice day to all of you.
I have a very sophisticated 665W power supply unit with an output failure. The board have 90 degree angled 10 to 18 pin soldered pcb modules all over the unit which make it impossible to probe without desoldering the modules. I have found an in-circuit shorted capacitor and diode readings that i have not desoldered and tested out of the circuit yet.
Before desoldering the components to test them out of the circuit, i would like to ask you if there is any possibilities to have an in-circuit shorted capacitor and diode readings by design? Let's say may it be possible that the DMM is reading short because of a low resistive parrallel connection to these components for example a resistor, transformer and such..
Is it always the case that having an in-circuit shorted reading capacitors and/or semiconducters, means that there is a short circuit in somewhere else or is it possible to find such in-circuit shorted reading components in a 100% perfectly functioning devices?
Thank you!
