6. Measure the voltage for TP34.
• If TP34 reads 0 or 1.6 volts, replace the control board.
(See the Repair/Replacement section of this
manual.)
• If TP34 reads otherwise, contact Technical
Support at +1.800.624.4422.
C. Bulb ignites immediately upon system
startup
1. Check if the jumpers on the ballast (JP300) are
properly installed. When the ballast is v iewed from
the bulb side, the jumpers should read
0 I I 0 I 0 0.
Adjust as necessar y.
2. Check the voltage di ff erence between TP22 and
TP23 on the control board:
• Turn o ff system power
• Connect the positive multimeter probe to TP22
and the negative probe to TP23
• Turn on system power
• If the voltage di
ff erence is around 12V, proceed
to step 3
• If the voltage di ff erence is around -1.3 volts,
replace the ballast (See the Repair/Replacement
section of this manual.).
3. Check the voltage of TP32. If it does not read 3.3
volts, replace the control board (See the Repair/
Replacement section of this manual.).
D. LCD display is blue or completely dark
Power on the light source:
• If you hear the fans running, or if the power
button is lighted, perform steps 1 – 3.
• If you don’t hear the fans running, and the
power button is not lighted, perform step 4.
1. Check if the cable between the control board and
front display board is connected properly. Adjust as
necessary.
2. Insert the bulb, close the bulb door, and measure the
voltages of PD1 and PD2 on the control board.
• If they do not read 3.3 volts, replace the control
board. (See the Repair/Replacement section of
this manual.)
• If they do read 3.3 volts, proceed to step 3.
3. Measure the voltage across the C47 and C48
capacitors (directly beneath the display board cable
on the control board side).
• If they read 3.3 volts and 12.3 volts respectively,
replace the display board (See the Repair/
Replacement section of this manual.).
• If not, replace the control board (See the
Repair/Replacement section of this manual.).
4. Make sure that the 6-pin power cable from the
ballast to the control board is connected.
• If the power button lights up, perform steps
1 – 3.
• If the power button still does not light up,
replace the control board (See the Repair/
Replacement section of this manual.).
E. Fan does not run
1. If one or both fans are not working, an E-4 (ballast)
or E-5 (bulb) error should display on the LCD
screen. Con
fi rm this.
2. If both fans do not work, measure the voltage on the
10.2V test point on the control board (underneath
lamp status connector).
• If it does not read around 10.2 volts, replace
the control board (See the Repair/Replacement
section of this manual.).
3. If only one fan works, switch the fan connectors
between the working and non-working fans.
• If non-working fan still fails to run, then it is
faulty. Replace it. (See the Repair/Replacement
section of this manual.)
• If the non-working fan begins to run, but the
working fan stops running, then the control
board is faulty. Replace it. (See the Repair/
Replacement section of this manual.).
F. Light source does not switch from
STANDBY to RUN mode
1. Check if the bulb is lit. If it is lit, go to step 2. If it is
not lit, then go to diagnosis strategy A.
2. Press the brightness up and brightness down buttons
on the membrane. Check if the mini brightness
meter in the top right corner of the display increases
or not.
• If the meter does not change, remove the front
panel and check if the front panel membrane
connector is fully connected to the display
board. Adjust as necessary.
• If the meter does change and the membrane
is properly connected, cycle the light source
power.
- As the LCD powers up, check the so  ware
version numbers.  ey should read at
least SW REV P 1. 2 and SW REV P.1.2
consecutively. (
 e revision numbers may
be higher if newer so  ware versions are
installed.)
- If the version numbers are not at least
1.2, contact Technical Support at
+1.800.624.4422 for so
 ware updates.
- If the version numbers are adequate,
contact Technical Support.
