how repair power supply when voltage is not present in secondary side
- how repair power supply step by step checking mathod
- first check to 300V on primary side main capacitor
- Before checking the primary side first open the eht (fly back transform) 110V supply jumper
- 300V is not present .(I)Solution:- check diode bridge ,fuse,mains wire
- 300V present but voltage is not come on secondary side (I)solution:- check the transformer drive transistor e.g 1802 or STR 8656 etc when it fault then replace it and also check the two 120k ohm resistor also check the small pf capacitor
- check the transistor near the uptocupler transistor number is C1015 or C764
- also check the transistor C2655 OR C3807
