A bit late for the answer but I think the offending problem lies in the de-gaussing circuitry of the Sony monitor. When switched on, it initially will degauss the screen, this normally involves a PTC via the ac supply and coils around the back of the CRT. This is normal for this monitor and have seen this when safety testing.
On the IPS system issue we have a problem with the system tripping with an Isolation TX on a stack system. (high inrush current probable cause)
My question/s is this, can a stack system with a leakage current over IEC601 guidelines without an ISO TX fitted be used on the IPS system?
What prevenatative measures have or can be put in place to prevent use of the stack on non isolated IPS supplies?
Appreciate any views on the subject!
