This one is a 12V car transformer for a Philips CD player. It stopped working one day, LED no longer lit, no voltage.
The only large cap in there is WISDOM 1000u 10V 85C, which was connected in parallel to the 5V output. Once I took it out the LED lit again and I registered 5V on the output side.
I don't have specialized equipment to test it, but doing a simple test: Apply 5V, then use multimeter to measure drain time... well once I took it off the power I never measured anything close to 5 volts.
