Check your fans, sounds like a thermal shutdown. The fans are 12vdc with a sense line. Red and black power, blue is the sense line. disconnect the fan connector and check the fan with a 12vdc supply. then check the sense line for signal feedback.

After five minutes of working properly, the Cine1000 projector goes dark and the ready lite goes out. The power lite stays lit. The lamp has 881 hours. I checked the menu and auto power selection is off....

The ambient temperature in the room is to high.
Try lowering the room temperature. If that doesn't work
get a small fan and place it near the projector to provide
extra cooling. The projector is running border line on
high temperature and just needs a little extra cooling.

The lamp reset...should only be used when you replace
the lamp..with a new one...The reset will start the clock
running on the number of hours the new bulb has used..

Will not turn on, red light flashing next to the menu button

if the fans don't turn on, they may be bad and needs replacing or rewired. if the fans turn on but not the lamp, the colorwheel may be bad (listen for a high-pitched whir when you switch it on. if no whir, replace the colorwheel). if the colorwheel is ok, replace the lamp.

This is something that cannot be easily guessed at. There may be a failure in part of the power supply, and on one of the processor boards.

You will have to have the Samsung service rep do the necessary repairs on your set.
