Power out unit turns off temporarily (between 1 second and 5 seconds) or off for good. If I was to have a hunch, it appears to be something like a fan not working and the unit shutting down when over heating, but this is just a laymans guess. the word --powerout-- flashes on the unit and off she goes... anyone??

To display memorized error (Protective operation)
status:
1. Turn power on.
2. Press the CHECK button on the remote controller
continuously for 5 seconds.
3. "- -" will be displayed on the remote controller display.
Note: Display only for "- -". (No transmitting signal, no
receiving sound and no Power LED blinking.)
4. Press the "TIMER" or button on the remote
controller. The code "H00" (no abnormality) will be
displayed and signal will be transmitted to the main
unit. The power LED lights up. If no abnormality is
stored in the memory, three beeps sound will be
heard.
5. Every press of the button (up or down) will increase
abnormality numbers and transmit abnormality code
signal to the main unit.
6. When the latest abnormality code on the main unit
and code transmitted from the remote controller are
matched, power LED will light up for 30 seconds and
a beep sound (continuously for 4 seconds) will be
heard. If no codes are matched, power LED will light
up for 0.5 seconds and no sound will be heard. 7. The breakdown diagnosis mode will be canceled unless pressing the CHECK button continuously for 5
seconds or operating the unit for 30 seconds. 8. The same diagnosis can be repeated by turning
power on again.
• To clear memorized error (Protective operation) status after repair:1. Turn power on.
2. Press the AUTO button for 5 seconds (A beep
receiving sound) on the main unit to operate the unit
at Forced Cooling Operation mode.
3. Press the CHECK button on the remote controller for
about 1 second with a pointed object to transmit
signal to main unit. A beep sound is heard from main
unit and the data is cleared.
• Temporary Operation (Depending on breakdown status)
1. Press the AUTO button (A beep receiving sound) on
the main unit to operate the unit. (Remote control will
become possible.)
2. The unit can temporarily be used until repaired

Turn On the unit with the remote controller
Wait until "no disc" appears in the unit's display
Press Pause, 3, 1, 4, 1, 5, 9

The problem you're describing is a classic symptom of a defective fan--some fans simply have + and - power connections. However, other fans have a third, yellow wire, for sending a pulse to the main board to tell it that the fan is indeed running. If the main board doesn't get the signal, it's internal programming instructions perform a shutdown in case of any error condition--protects the unit against excessive heat, current draw, etc. MAKE SURE THE DUST FILTER IS CLEAN! A dirty filter causes the fan to pull harder, increasing current draw, possibly triggering the symptom. The other possibility is a defective power supply causing an over-current condition. Again, the main board senses this and cues a shutdown. You'll need to send the unit out to a repair facility to confirm a diagnosis. Any reputable shop will give you a quote first with an explanation of the problem.

Here is the proceedure to replace the lamp and reset the lamp hours.
Lamp Replacement Procedure:
1. Press the POWER button to turn off the power.
2. Wait for about 1 minute until the cooling fan stops.
Note:
The lamp cooling fan will continue to operate for about 1
minute after the power is turned off. Do not unplug the AC
Cord from the outlet until the fan has stopped. Avoid
interrupting the power by using circuit breakers or switchable
power strips.
3. After the cooling fan has stopped, unplug the AC Cord from
the outlet.
Note:
Please wait more than one hour before replacing the lamp.
[ Forced cooling function ]
If you need to replace the lamp more urgently:
- The Projection display has a forced cooling feature.
After the POWER button is turned OFF, and during the
first minute of the normal cooling fan operation, press
the VOLUME UP button on the unit and CH UP key on
the remote at the same time for more than 5 seconds.
The cooling fan operates for about 10 minutes. (LAMP
LED will flash 5 times every 5 second and POWER LED
will flash red for 10 minutes.)
4. Remove the Front Cover Unit from the latches.
5. Turn the Knob to the left.
6. Pull the Lamp Cover out.
7. Loosen the Screw on the Lamp. Then, pull the Lamp.
Note:
Because the Lamp may still be hot, use caution when
handling.
8. Install the new Lamp, and tighten the Screw.
9. Install the Lamp Cover, and turn the Knob to the right.
10. Install the Front Cover Unit.
Lamp Time Reset Procedure:
Be sure to reset the Lamp time to "0" after replacing the new
Lamp.
1. Plug in the AC Cord, and turn on the power by pressing the
POWER button.
2. Press and hold the VOLUME DOWN button on the unit and
the SPLIT key on the remote together for over 5 seconds
