You need to get a service manual, either Google, for one, or contact the manufacturer and ask them for a copy. Then you will be able to determine these parts and values. Usually though, the values are on the components? and resistors have color codes? It indeed seems odd, all those resistors faulty at the same time, is unusual to say the least. Are you sure your power supply voltages are correct? As if this isn't all 100% nothing else can be.

The filter needs replacing. Do you sell replacement filters for model CP-X1250?


Take the filter to the local electronics repair shop and ask them for some filter material like the one in the unit. Then cut it to size to fit like the old one.

Is the only difference between at CP-X1200 and CP-X1250 the bulb, or is the ballast circuit different too? Just thinking how easily I could boost the brightness from 3500 to 4500 lumens.


Model: CP-X1200 ( Lamp)
Part#: DT00591
Lamp Type: UHB
Wattage: 275 Watts
Lamp Hours: 2000 Hours

Model: CP-X1250 ( Lamp)
Part#: DT00601
Lamp Type: UHB
Wattage: 310 Watts
Lamp Hours: 2000 Hours

I'm not sure but I would think the same ballast board is used, and the trimpots adjustments set in the factory.
If you fiddle with it, you may not be able to get the tube to strike on startup, or worse you can explode the lamp.
Also the extra heat generated may degrade the optics and LCD panels.not mention melting the housing.
Better to leave well alone.

Hitachi projector cp-s318 and the pictures give off a red tint.


Hi,

Make sure the Computer Input is set to VGA, Computer, or RGB (depending on which projector model you have). Go through the menu settings of your projector.

Hope this helps

Color shift blue tint


This could also be a setting. If you are using component video as a connection, make sure that the unit is set for RGB if coming from a laptop or other computer system. If the projector is set to YPrPb, the picture will look purple or bluish as you describe. Change the setting to RGB and all should be well.
