I am trying to solve an SMPS that keeps blowing it's MOSFET.
I bought the Blue Ring tester from Anatek. I tried contacting them but they do not answer the phone and the forum is dead. Will not even let me Log in once I have registered.
When I take the transformer out of the board and test the primary I get full green lights.
When in the board I get no lights indicating a short.
When I take out the 2 1000uF 100v Filter caps from the secondary side I get full green lights.
However, these to caps pass ESR, Capacitance, Multimeter charging, and even a 30v Leak test. I believe they are good.
Is it possible they are causing a false reading of short on the Blue Ring tester?
Thank You
