1610HD Blank screen causes Color wheel fault

When I use the blank screen function on the projector, the screen blanks with the message

"Press Blank again..." for about 30 seconds or so. I then see the lamp turn off and the two amber lights flashing on top indicating a problem with the color wheel. Power cycling the projector restores operation until the screen is blanked again. Does anyone else have a problem with the screen blanking feature causing a color wheel fault?
