6.1 Solving Power and Startup Problems

When you see nothing but black on the screen, it is probably a startup problem. If the image is there,

but it is not right, it is an image problem, covered in the next section.

Things to check if you have no image:

• Is the AC Master switch lit?
• Is the unit plugged in?
• Is there power in the AC mains?
• Press the arrow keys of the remote control like

this: up-down-up. This starts the On-Screen Diag-
nostic Code, which should appear whether the
lamps are on or not. These two bright LEDs blink
in a pattern to tell you why the lamps are not lit.

See “Reading the On-Screen Diagnostic Code” on
page 112 to interpret the code.

• If the lamps are lit and you can see menus, but

you don't see the video image, check Curtain. In
the main menu, select Curtain and press

ENTER

Highlight Curtain On/Off and press

ENTER

. If Cur-

tain is on, press

ENTER

to turn it off.

• Check Test Pattern. Maybe the black test pattern

is on.

There are no user serviceable parts in either the
electronics module or the power supply.

This is the normal startup sequence:

1. AC power is applied. Either the main circuit

breaker switch is turned on, or AC is reacquired
after a power loss.

2. Several LEDs on the electronics module turn on

and off as the Panther gets started. This initializa-
tion phase is about 15 seconds.

3. After initialization, the Standby LED turns on,

and all the fans stop. However, if Auto Lamp On
is enabled, this step is skipped, the fans stay on,
and lamp ignition starts right away.

4. Lamp Ignition: The system receives an On com-

mand from the remote or RS232 or Auto Lamp
On.

5. All fans run. The system attempts to ignite each

lamp in turn with a one second delay between
each lamp start. It always starts with Lamp 1 fol-
lowed by lamp 2.

If the Lamp Bay door is open, and its interlock switch is
open, no lamps will ignite. If lamps are already on when
the door opens, they all go off. When the Lamp Bay
door is opened, the Lockout LED goes red. To relight

lamps, you must close the Lamp Bay door and cycle
AC power.

If both exhaust fans fail to turn, or the power supply fan
fails to turn, the lamps will not ignite and will be
automatically turned off if they are on. If only one
exhaust fan fails, the system runs normally. The long,
squirrel cage fan that blows on the LCD has no sensor
and does not affect lamp operation.

6. The requested lamps are on.
7. When the system receives an Off command, the

lamps turn off immediately. The lamp LEDs go
out.

8. All fans stop, and the Standby LED turns on.

Lamp strike sequence

The lamps always ignite, or try to ignite, in this

order: First 1 then 2.

When you set the Lamp Count for 1lamp the Pan-

ther will try to light lamp 1 if unsuccessful it will
then try lamp 2.

You cannot choose which specific lamps to light.

The firing sequence is always 1then 2

After the lamps are lit, the system continually

monitors the state of the lamps. If any lamp fails,
that lamp is marked as failed and Panther will try to
light the other one if there is one.
