Thermal switch
There is the thermal switch SW902 inside of the projector to prevent the internal temperature from rising abnormally. When the internal temperature reaches near 100 C, turn off the AC main power supply automatically. The thermal switch is not reset to normal automatically even if the internal temperature becomes normal. Reset the thermal switch following procedure. Check the resistance between terminals of thermal switch by using the tester. If it has high impedance, thermal switch may be in...

Disassembly Cleaning
Disassembly cleaning method should only be performed when the unit is considerable dirty and cannot be sufficiently cleaned by air spraying alone. Be sure to readjust the optical system after performing disassembly cleaning. 1. Remove the cabinet top and main units following to Mechanical Disassemblies. 2. Remove the optical base top following to Optical Unit Disassemblies. If the LCD panel needs cleaning, remove the LCD panel unit following to LCD panel replacement. 3. Clean the optical parts...
No Power
The possible causes of No Power are listed below. Please check following and refer to power supply and protection circuits diagram in the figure opposite. 1. Stop the operation of power supply circuit due to detection of abnormality. - Detected the abnormality on the secondary power supply lines. Power failure detection diodes detect an abnormal voltage on the power supply. Check the shortage of secondary circuits, ICs, condensers, etc. - Detected the operation stop of cooling fans. Power...
