Hi Erick, actually Colombia is 120V/60hz, the projector I have is the model for USA and Canada that works perfectly in here. The projector is the same for Europe and America, if the back cover is removed you gain access to the transformer where the contacts can be switched to work with any voltage, there is also a lever that can be moved to 50 or 60hz position. I have the adapters that where you can plug the circular European prongs so the cable can connect into the flat American sockets, so I can use the American cable or the European without any problem.
I already contacted Phil Johnson, he wasn't really of much help, actually he made me an offer for the projector. He is offering one of this models for $1400 USD !!!
