TROUBLESHOOTING
Symptoms: Check points:
No power - Is a power cord connected?
- Is the main power switch (# 34, on the back of the unit) switched to "I"?
- Check fuse! (#35)! (see page 14)
Bright and hazy spots in the picture - Is the mirror on the reflector head (#10) or the glass dirty?
If yes clean it BUT BE CAREFUL - (see page 14)
Low light - Is the lamp worn out?
- Are you using the Visualizer with the correct voltage?
- Is the lamp correctly placed in the socket?
- Check the lamp change slot (#9). Is the black metal plate fixed? (see page 13).
No light - Is the light switched off (LIGHT keys #26, #27)?
- Is the lamp-changer (#8) in the right position (see page 12)?
- Is the lamp burned out?
- Is the light slot covered?
The right edge of the picture is black / the right
edge of an object isn't illuminated (using the
Visualizer as a video camera) - Switch off the light with the LIGHT off key (#23) and work with room light.
(This is not a failure of the unit, see page 8 - Lighting)
No monitor picture - Are the switchable outputs (Composite, Y/C or RGBS) switched off?
Switch on with the IMAGE on key (#22)
- Is the IRIS closed? Press the IRIS bright key (#20)
- Check cable connection and input of monitor/projector!
- VZ-45b: Check if the monitor or projector is capable to display a S-VGA-
picture (with a horizontal frequency of 31.25kHz and a vertical frequency
of 50Hz)
- VZ-45b: Check if the correct Sync-Mode is selected (see page 6)
Reflections / Glare - See detailled description on page 9.
Poor picture quality on the projection screen
(using the Visualizer together with a projector) - This is mostly due to bad adjustment of the projector. Connect a
TV-monitor to the Visualizer. If the picture quality is good on the monitor
check the adjustment of the projector.
Autoiris does not work - The autoiris function is switched off when using the IRIS keys (#19,#20).
It is switched on again when using the ZOOM keys (#15,#16)
Bad picture quality - Check the set-ups and quality of your monitor or projector.
- On VZ-35b and VZ-45b, check the camera set-ups (see page 16-19)
False colors
- NTSC: adjust color phase of monitor or projector
- Adjust the white balance (see page 15)
Too much green in the picture
(when using the RGBS output) - Use either SYNC ON GREEN or SEPARATE SYNC but not both at the
same time! (see page 5 or 6).
No color (B/W only) - Check the TV standard of the monitor or projector (PAL/Secam/NTSC)
- Check color adjustment of the monitor or projector
- Check the Y/C cable (if there is color when using the composite video
output, the Y/C cable may be defective)
No stable picture (Sync problems)
- RGBS-output: Check Sync connection. Use either SYNC ON GREEN or
SEPARATE SYNC (see page 5 or 6).
- Adjust V-Hold on monitor or H/V-frequencies on projector
- VZ-45b: Check if the monitor or projector is capable to display a S-VGA-
picture (with a horizontal frequency of 31.25kHz and a vertical frequency
of 50Hz)
- VZ-45b: Check if the correct Sync-Mode is selected (see page 6)
Vibrations in the picture - Place the Visualizer on a solid table, so that the unit is protected from
movements of people working on that table.
Picture is too bright (when using an LCD video
projector) - An LCD projector should be adjusted for Visualizer projection
see page 10 for details.
VZ-35b: Wrong colors or bad picture quality
(using the RGBS / YUV output of VZ-35b) - Check if the Visualizer and the monitor or video projector are both switched
to either RGBS or YUV. The VZ-35b can be switched to the other standard
by simultanously pressing: SAVE, IRIS open and IRIS close.
