Digital Display not ON.
1. Check for loose connection on plug J5.
2. Check for 230 V.AC on terminal block positions 1 & 2. If correct, check X1 transformer output for
115 V.AC. If not measured, replace transformer.
Bulb goes out during operation.
1. Xenon power supply overheated; thermal switch open. Check power supply blower(s), air inlets and
outlets unobstructed. See power supply manual.
2. Xenon bulb depressurizing. Check for envelope discoloration; replace if defective.
3. Fluctuating AC source voltage actuating brownout or spike protection circuits in xenon power supply.
See power supply manual.
4. Lamphouse cover loose or open. Close and secure.
Noise in theatre sound as bulb ignites.
1. Faulty RF suppression capacitor(s). Remove and test C1. Replace if defective.
2.
Lamphouse, power supply, or sound system not properly grounded. Connect to adequate earth ground.
Excessive light flicker..
1. Faulty or aged bulb. Check for cracked or sagging electrodes; replace if defective.
2. Excessive ripple in DC output. See power supply manual.
3. Arc stabilization magnet reversed. NORTH pole should point toward operator’s side. Check with
compass if required.
Reduced light output.
1. Normal bulb aging. Increase output current. DO NOT EXCEED MAXIMUM CURRENT LEVEL
SPECIFIED BY BULB MANUFACTURER.
2. Soiled reflector. Clean using commercial glass cleaner; USE NO ABRASIVES.
3. Soiled heat filter, projection lens, or large lens. Clean as required.
4. Bulb or reflector position altered. Correct alignment; see preceding OPERATION section.
Extremely long duration between ignition pulses.
1. Low DC “no load” voltage from the xenon power supply. Check “no load” voltage; see power supply manual.
2. Defective spark gap. A “Ping” sound is normal; excessive “Hissing” is abnormal. Replace if defective.
Colors burning or fading prematurely.
1. Bulb focused to “hot spot.” Refocus bulb to flat field with iris fully open and spot size control handle
(“trombone”) fully forward.
2. Heat filter glass reversed or peeled. Check for
coated surface toward bulb; replace if coating peeled.
3. Reflector coating peeled. Replace if defective.
