Thanks. NEC did not have a solution for us, but the solution for us was to replace the bulb. You'd think they would make that a bit more obvious!
Thanks.

Both power light and status light a solid red with no response to any buttons indicates the bulb timer has expired. You need to reset the timer by pressing and holding the left arrow key, the right arrow key and the power button all at the same time for a few seconds.
If there are no problems, the projector will fire up, but you must replace the bulb as it will fail soon and perhaps explode when it does.
Take care

Hello!
After 2 years I finnaly solved the problem. There was a flaw in the lamp´s temperature circuit. A technician disassambled my BENQ PB8253 unit and fixed the problem. Charged me US$ 75.00. I´m in Brazil.
Hope this can help.
I found a solution that worked for me:
1. Turn on the projector
2. Press "Power > Left > Left >
MENU" (Opens the system menu)
3. Choose "RD Menu"
4. Choose " EEPROM Restore" (the projector
turn off and the power lamp blink red for about 1 minut. Then it stops)
5. Turn on the projector again and it should work again
