Indeed, you're right. I mixed up frequency and voltage. Sorry for that.

That last part confirms we he told me too. He replaced something (I don't
know what, but I don't think it was the complete part) and the monitor
continued to function for more than a year after than before it just died
on me.
Thanks for your insight, it made me a bit more knowledgable }:-)
