2.1 What Kind of Problem Is It?
2.1.2 Startup Problems
Startup problems usually mean the screen is black – no image, no menus. If the display has power and
the electronics are working, you can learn a lot by watching the LEDs (inside the cube, viewed with
the screen off) or the On-Screen Status Codes (viewed with the screen on).
Follow these steps to determine what the problem is:
1. Press the
button on the remote control.
MONITOR
Do you see a Monitor Status menu?
a) Yes – This is not a startup problem. Turn to
section "Image Problems" on page 30.
b) No – Go to Step 2..
2. Do you see a colored light in the lower right part
of the screen? It may be flashing or steady. It may
have two colors. It will be out of focus and look
strange.
a) Yes – This light is flashing in a non-secret code.
See "How to Read On-Screen Status Code" on
page 22 to learn how to read the code.
b) No – The electronics module is not operating.
Go to Step 3..
3. Remove the screen. Is the circuit breaker inside
the unit lit?
a) Yes – Go to Step 4..
b) No – Power problems: Check line cord, source
AC power, circuit breaker switch.
4. Are any LEDs lit on the electronics module?
a) Yes – These LEDs will tell you the state of the
display. See section "How to Read the Inside
LEDs" on page 24 to learn what these LEDs
mean.
b) No – Go to Step 5..
5. Is the power supply on the left wall of the cube
connected to the left side of the electronics mod-
ule?
a) Yes – Either the power supply is dead or the
electronics module is dead. Or both. Swap the
power supply with a known good supply. (See
section "Replacing the Power Supply" on
page 68.) If that does not help, then swap the
electronics module with a known good one. See
section "Replacing the Electronics Module" on
page 70.)
b) No – Turn off AC power. Connect the power
supply to the electronics module. Turn on AC
power again.
