high voltage!
Do not open the TFT Display housing! This is not necessary in a
service situation.
Do not insert objects into the TFT Display housing!
Electrical voltage!
Noncompliance can lead to death, physical injury or property
damage.
After completing all service work and attaching all system covers,
you must perform a protective ground wire test according to
ARTD-002.731.17... .
The protective ground wire resistance must not exceed 0.2 ohms.
Risk of being burned by hot parts or components!
Noncompliance can lead to light or medium burns, especially of
the hands.
Once the covers have been removed, parts or components (e.g.
power components, heat sinks, solenoid brakes) become acces-
sible which may exhibit temperatures of up to 50°C in operation.
To prevent burns, switch off the system power supply before con-
tacting any parts or components and let the system cool off for at
least 5 minutes before resuming work.
Electrical voltage!
Noncompliance can lead to property damage.
ESD protection guidelines must be observed when servicing.

•It can also be checked by swapping the low voltage connectors from one to the other
installed TFT display.
TFT Display 1
•Depending on the malfunction, ensure that the display is the defective part.
- Check the switched-mode power supply.
- Check the connectors (low voltage input, video signal input)
- Check the video signal of the MEMOSKOP with the SMPTE test pattern
(300mV Sync +/- 10%, 1Vss +/- 10% (in 100% peak white field)).
- Check the input selection switch (at the bottom side of the TFT display).
The switch can be set in 3 positions:
1. Position to the rear: VGA input selected
2. Middle position: BNC-Input selected, 75Ohm termination resistor is off.
3. Position to the front: BNC input selected, 75 Ohm termination resistor is on.
- Check the settings of the on screen menu, in accordance with the user manual.
The TFT display includes no repairable parts and has to be
changed completely if defective.
