It sounds like the lamp is going. Do you know how many hours of use are reported on the lamp?
Many times these projectors have circuitry to shutdown when they suspect the lamp is near the end of life. Lamp hours vary and usually will go up to and even beyond expectancy, but there is occasions you can receive a bad lamp and have it blow in a matter of hours...not common but it does occur.
FIRST LOCALIZE THE UP/ DOWN/ LEFT/ RIGHT AND MIDLE BUTON- ON FUNCTION CONTROL

The power supply needs to provide a constant current flow to the lamp. Any small change or in the current will be seen as flicker in the lamp and projected onto the screen. Problem could be with low voltage power supply, the ballast or the lamp it self is beginning to wear out.
My solution sounds dumb, I had the same issue. Took the lamp cover off the bottom. The screws were loose holding in the lamp. Maybe they heat and expand and eventually work their way out and the lamp doesn't make good contact. Just tightened mine up, the unit would power off after 45 minutes prior. Been on now for 5 hours, no trouble.
Tried to turn it on? Sounds like you need to replace the lamp. However, I got an additional week out of my unit. Although poorly dimmed and the red Lamp light blinked constantly for that one week, at least it gave me enough warning to seek out a replacement. But so long as you're not mistaking the Power/Standby or Timer light for the Lamp light then I would have to agree with you.
