Inspection Procedure
RESET :
Please press Menu button on the projector panel to enter Factory Reset Function then choose
YES and press Enter to see if it works. This action will allow you to erase all end-users settings
and restore the original factory setting.
Hi-Pot and Grounding Test :
Hi-Pot Specification : 1.5kVAC, 10mA, 2 seconds.
Grounding Specification : 12VDC, 25A, 0.1 ohm.
Clock and Clock Phase :
Test Signal : 1024*768 @ 85Hz
Test Pattern : Line Moire Pattern
Check and see if image sharpness and focus is well performed.
If not, readjust by following steps.
1.) Enter Digital Conversion menu and select Clock Function to adjust the total pixel
number of pixel clock in one line period.
2.) Then select Clock Phase Function and use right or left arrow key to adjust the value to
minimize video flicker.
R, G, B and White Colors Contrast :
Test Pattern : 64 or 16 R, G, B and White colors Intensities Pattern
Please check and see if each colors is normal and distinguishable.
If not, please return the unit to repair area.
Screen Uniformity and Flicker :
Test Pattern : Full White Pattern
Please check and see if its in normal condition.
If not, please return the unit to repair area.
4-6
H76
Dead Pixel/Blemish Pixel :
Test Pattern : Gray 30, Blue 180, White, Dark, Red, Green and Blue Pattern
Please check and see if there are dead pixels on DMD chip.
The total numbers and distance of dead pixels should be complaint with specification.
Check for Secondary Display Modes
Test signal : 1.) 640*350 @ 70.09/85.08Hz
2.) 640*480 @ 72.81/75.00/85.01Hz
3.) 720*400 @ 70.08/85.04Hz
4.) 800*600 @ 56.25/60.32/72.19/75.00/85.06Hz
5.) 832*624 @ 74.55Hz
6.) 1024*768 @ 43.48/60.00/70.00/75.03/85.00Hz
Normally when the primary mode 1024*768 @ 85Hz is well adjusted and complaint with the
specification, then the secondary display modes will be great possibility to be complaint with the
specification. But we still have to check with general test pattern to make sure every secondary
modes is complaint with specification.
Factory Reset :
After final QC step, we have to erase all saved change again and restore the factory defaults. Please
select and enter Factory Reset Function to see if it is workable. This action will allow you erase all
end-users settings and restore the original factory setting.
