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.)



Yes, or if you accidently bump it with your knuckle while probing elsewhere
on the board, ouch indeed!
