Hi Everyone,

My AVR power led start blinking when I switch it on. I have removed the SMPS and checked the voltages. I am getting only +/-22V which is supposed to be +/-45V. All other voltages are ok. +/-45V goes to AMP pcb. I have visually inspected the SMPS pcb but I could not find any problem. Can you guys please suggest what can be the problem in this case.
I am attaching a picture of schematic. Thanks
