Family and visitors do not know or care how to look after projectors, so I'm looking at ways to prevent unauthorised use without moving the power cord. One step I have already taken is to remove the original remote, and programme my touchscreen remote so that a PIN is required before the projector can be used. That works fine, except a visitor today casually turned on the projector with the units power button, not knowing that it was still in its 'cooling down' state!! As we all know on here, 'hot starting' is bad for the lamp. So, any ideas on how you can prevent the power button on the unit from being pressed without making a cosmetic mess of it.
