WolfVision VZ-15 - Manual (Page 15)

15
Symptoms: Check points:
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 7 - 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 open key (#20)
- Check cable connection and input of monitor/projector!
Reflections / Glare - See detailled description on page 7.
Poor picture quality on the projection screen
(using the Visualizer together with a video
projector) - This is mostly due to bad adjustment of the video projector. Connect a
TV-monitor to the Visualizer. If the picture quality is good on the monitor
check the adjustment of the video 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.
False colors - Make sure that no neon light shines on the working surface
- NTSC: adjust color phase of monitor or projector
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) on video projector - Adjust V-Hold on monitor or HV-frequencies on projector
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.
Infrared remote control does not work - Change the battery! (see page 11)
- If the unit cannot be controlled with the infrared remote control even from
a close distance and with a new battery it may be due to a wrong frequency
(see page 12).
The lightfield on the working surface is much
larger than the recorded area.
Please note that the lightfield has to be a little bit larger than the recorded
area, otherwise it would not fit in all positions (on the working surface).
However if it is much too big check the following:
- First check if it is possible to adjust your monitor. Many TV-monitors do not
display the whole picture. Some show more of the right side, some more of
the left side etc. Check if there is an UDERSCAN function - with this
function you can display 100% of the Visualizer picture.
- If you are working with a projector (CTR) check the "blanking" of the
projector
- If you are sure that the lightfield is still much larger than the recorded area
and it is not due to a wrong adjustment of your monitor of video projector,
consult your Wolfvision dealer. The size of the lightfield can be adjusted
electronically using a special Wolfvision service software.
External Synchronization
For extrernal synchronization of the VZ-15 and adjustments of color phase, H-phase etc. please read the special
