1. Safety Precautions
1. 1. General Guidelines
- For continued safety, no modification of any circuit must be attempted.
- Unplug the power cord from the power outlet before disassembling this projector.
- Use correctly the supplied power cord and must ground it.
- It is advisable to use an isolation transformer in the AC power line before the service.
- Be careful not to touch the rotation part (cooling fan, etc.) of this projector when you service with the upper case removed
and the power supply turned ON.
- Observe the original lead dress during the service. If a short circuit is found, replace all the parts overheated or damaged
by the short circuit.
- After the service, all the protective devices such as insulation barriers, insulation papers, shields, and isolation R-C combi-
nations must be properly installed.
- After the service, check the leakage current to prevent the customer from getting an electric shock.
1. 2. Leakage Current Check
1. Prepare the measuring circuit as shown in Fig.1.
Be sure to use a voltmeter having the performance described in Table 1.
2. Assemble the circuit as shown in Fig. 2. Plug the power cord in a power outlet.
3. Connect M1 to T1 according to Fig. 2 and measure the voltage.
4. Change the connection of M1 from T1 to T2 and measure the voltage again.
5. The voltmeter must read 0.375 V or lower in both of steps 3 and 4. This means that the current must be 0.75mA or less.
6. If the reading is out of the above standard, the projector must be repaired and rechecked before returning to the customer
because of a possibility of an electric shock.

When performing the simultaneous input of the 4K image (resolution of 3 840 x 2 160 or 4 096 x 2 160) using the Interface Board for HDMI
2 input (Model No.: ET-MDNHM10), it is necessary for the firmware version of the Interface Board for HDMI 2 input to be 2.00 or later. If the
version is earlier than 2.00, the simultaneous process is not performed even if corresponding signal is input. Consult your dealer regarding
the version update to the latest firmware.
For details on how to confirm the firmware version, refer to “How to confirm the firmware version of the Interface Board (optional)”
f
To use the 3G-SDI Terminal Board with Audio (Model No.: TY-TBN03G), it is necessary for the firmware version of the 3G-SDI Terminal
Board with Audio to be 2.00 or later. Consult your dealer regarding the version update to the latest firmware if the version is earlier than
2.00.
For details on how to confirm the firmware version, refer to “How to confirm the firmware version of the Interface Board (optional)”
