Switching Power Supply Chirping, How to Fix?
'Chirping' comes from the power supply restarting over and over again. The typical cause is an external overload, but defective internal parts can cause the same effect. The power supply is trying to run but is encountering an over current condition that prevents the output voltage from rising to a preset level by a preset timeout of one second or less.

You mentioned bloated capacitors. Generally it is a single part that fails, either a diode or capacitor in the output stage. However a component failure in the feedback loop can cause the same effect.

Note that over time constant restarts will burn out the control IC or MOSFET. Testing with a good DVM could help find out where the proper rise in output voltage is being cutoff. Be careful! The primary side (before the transformer) has about 240 to 340&nbsp;vdc, very painful to touch.

It has been suggested and is recommended that all bloated capacitors be replaced with same value parts, rated for \$105^o C\$ and with a low esr value. Though the fail mode may not be a short, their value could drop to 1% of rated value, preventing a stable voltage from building up before the startup times out.

The 'chirp' sound is from an initial series of startup pulses in the transformer windings and core. On a good startup you would hear this just one time and it maybe too brief to hear.
