Yamaha- DPX-1100, It turns on for 1-2 minutes then turns off and the replace lamp light is flashing. I noticed it goes wierd colors like from green to blue to white before it turns off. Like the lamp is losing juice. Is this how lamps go out. I would think its all or nothing for a lamp. What else can it be? Just that I have never had a lamp go out and not sure what to expect if it does outside of total blackness. Your answers are surely appreciated. Is there a way to physically look at the lamp to tell if it is bad or gone? Can I test it somehow? Dave SLC, Utah
