Earlier im working a a Daytek DT-1704C 17" monitor. It powers up with no
HV. I was carefully 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 each 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 recewiving power. Any advice is appreciated. Thanks.

12 VDC | R2 / Though | (SCR or triac).
---//---o <--' | 1K o |

Apply the 12 V. The device should be off.
Touch the gate R2 - it should turn on
The significant problems we face cannot be solved at the same level of thinking we were at when we created them.
