How to test a thyristor?
I am working a a Daytek DT-1704C 17" monitor. It powers up with no
HV. I was prodding around the power supply unit and inside is a TF341M thyristor (I looked up the datsheet). Using the diode test on my DMM it measures 0.266V between gate and cathode both ways. Is this normal? or can a thyristor even be tested with a DMM? If the part is bad I suspect it is preventing some sections of the monitor from receiving power. Any advice is appreciated. Thanks. |
