I have a Philips LC 4433 Projector. When switching it on this morning, the projector displayed a green colour and nothing else. None of the buttons on the machine would work. The only one that worked was the 'Standby On' button. Their doesn't appear to be a master reset button anywhere on the case.

Does anyone know what the problem is as it was working fine on Friday afternoon. It is needed for an assembly on Wednesday morning. Any help will be greatly appreciated.
