julienruc :
The pin has electricity or the cable? Is this while it's plugged on the monitor and to the wall socket? Or you conneted to the wall socket and u touched it?
Its plugged to the monitor but not the wall socket, i have an extension with on/off red light indicator where the cable plugged in to the extension, it shows dim red light. I supposed the capacitor has something to do with it but does it cause any problems?
