Question

hi, i turned my projector on as normal today and usually when i press the power to my sky box on the image comes on straight away. now however i just get the blue screen with a no input message. then the projector power ight goes to red even though its still on. at this point no remote control functions work, and the only thing i can do is turn it off at source. could the bulb need replacing? im not sure as it still projects the blue screen. any ideas?
