My PLV z2 has been happliy running via component inputs for couple of months. Yesterday tried connecting it to the DVI-out on my home PC. This DVI out is used to feed the monitor of my PC so I know it works ok. However, when the DVI lead is plugged into home PC, and the PLV z2 is switched on, it blew the fuse on my PC. Repeating the exercise it tripped my Earth leakage circuit breaker. Anyone else experienced anything similar? Graphics card with DVI out on my PC is an ATI All in Wonder. It is very curious.. some voltage feeding back into the PC from the PLV z2???
