Hello everyone in this vry helpful forum .
Am trying to understand this circuit that belongs to the entry part of an electronic card .; the output goes to a lamp .
Actually i have two identic cards , but one is not working ; So when i measure the number 2 (yellow one) capacitor on the working card i get 220 v , but none on the other , so i tried to change that , but same thing no light at output .
How could i identify the faulty parts ??
Here's the shematic and the card itself :
