Hi,

what kind of problem do you have with the monitor?

Is the heatsink connected to ground?
I have an AT power supply, where the chopper transistor has a metal
backside, connected to the 300VDC from the rectifier.
So the heatsink is live under normal condition. (Quite a surprise if
someone wants to feel for the temperatur. Ouch.)

I´ve check the transistor but is fine (this is a chopper tansistor
from a SMPS from a 15^ monitor) can the chopper transformer be shorted
to ground? How can I find out? I´ve red about ¨ring test¨ but some
of the equipment listed I do not have.
Is the only cause of this a short to ground? Can there be something
alse happening?
Thanks.
