Based on your description of the issue, it is possible it is the same issue, but also possible maybe something else. It seems like with the faulty IEC switch there has been a common behavior where if you actually roll it on slowly rather than quickly switching it on, it tends to “catch” and the unit successfully powers up. Give that a try and let us know if it works in the meantime while you get the issue sorted out.
