Do not use the Japanese power lead (2 prong type) that comes with the Japanese Panasonic AE300 projectors. This is especially important if you are using an isolating transformer (240V to 110V). The AE300 should use an Earthed power lead (3 prongs both ends) otherwise, in all seriousness, the unit or any other device you connect it to has the likely hood of going pop! Myself and another electrical engineer are going to try to work out what the japs have done on this occasion and why the product has been sold without an earthed power connector. We'll let you know our views soon.
