9. MONITOR

When performing such work as installing and removing the monitor, inserting and disconnecting the external connectors to and from monitor, be sure to disconnect the power connector (plug) before starting work. Proceeding the work without following this instruction can cause electric shock of malfunctioning.

Using the monitor by converting it without obtaining a prior permission is not allowed. SEGA shall not be liable for any malfunctioning and accident caused by said conversion.

Primary side and secondary side

The monitor's circuit which is divided into the Primary side and secondary side, is electrically isolated. Do not touch the primary side and the secondary side simultaneously. Failing to observe the instruction can cause electric shock, and this is very dangerous. When making monitor adjustments, use a non-conductive driver and make adjustment without touching any other part other than the Adjustment V.R. and Knob. Also, be sure not to cause a short-circuit to the Primary side and the Secondary side. If short-circuited, it can cause electric shock or malfunctioning, which is very dangerous.

High tension Voltage

Some of the parts inside the monitor are subject to high-tension voltage in excess of 20,000 volts and very dangerous. Therefore, do not touch the monitor interior. Should soldering & paper wastes, etc. be mixed in the monitor, turn the power off so as not to cause malfunctioning or fire hazard.

 

Connecting the CRT and PCB

For combining the CRT and PCB, use the specified part No. to maintain the status of adjustments made at the factory. The anode of the CRT itself will be accumulitavly charged as time elapses, generating high tension voltage which is very dangerous. The monitor should be used with the Chassis, CRT and PCB assembled. When repair, etc. is required at the time of malfunctioning, be sure to send it in an "as assembled" condition. If these are dissassembled, what's charged to said high tension voltage can be discharged, cuasing a very hazardous situation. Therefore, under no circumstances should it be dissasembled.

Static Electricity

Touching the CRT surface sometimes cuases you to slightly feel electricity. this is because the CRT surfaces are subject to static and will not adversly affect the human body.

Installation and removal

Ensure that the Magnetizer Coil, FBT (Fly-Back Transformer), Anode Lead and Focus Lead are not positioned close to the sheet metal work's sharp edges, etc. and avoid damaging the insulated portions so as no to cause an electric shock and malfunctioning. (For the name of parts, refer to the above figures.)

For the purpose of static prevention, special coating is applied to the CRT face of this product. To protect the coating, pay attention to the following points. Damaging the coating film can cause electric shock to the customers. For the caution to be heeded when clearing, refer to the Section of Periodic inspection Table.

Do not apply or rub with a hard item (a rod with pointed edge, pen, etc.) to or on C.R.T. surfaces.

Avoid applying stoickers, seals, etc. on the C.R.T. face.

Do not remove aluminum foils from the C.R.T. corners. Removing the aluminum foils can cause static prevention effects to be lowered.

 

 

Monitor adjustments have been made at the time of shipment.

Therefore, do not make further adjustments without a justifiable reason. Adjusting the monitor which contains high tension parts is a dangerous work. Also, and erroneous adjustment can cause deviated synchronization and projection fault, resulting in malfunctioning.

When making adjustment, utilize a resinous Alignment Screwdriver. Servicing with bare hand or using conductive tools ca cause electric shock.


 

 

Remove the Mask Holder to make monitor adjustment.

 

There are 2 Monitor Manufacturers (NANAO and SANWA). The adjustment control layout differs depending on the specific maker. When performing the adjustment, check the maker by referring to the following.
