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.
The advice of their elders to young men is very apt to be as unreal as a list of the hundred best books.

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.
