Problem

Solution

No power light

Unit not turned on
Unit not plugged in
Fuse blown
No power at plug

No picture

Video source not selected
No video source connected or operating
Projector/Monitor not turned on
Projector/Monitor not connected correctly
Bad video cable
Unit in freeze mode
Check brightness and contrast levels

Colors bleeding

Check termination
Check projector/monitor termination
Contrast set too high
Color set too high

Picture not stable

Check interface cables
Sync cables are swapped or not connected
Input source not selected correctly
Check input terminations
Projector Fast/Slow Horizontal time constant. Should be set to fast.

Incorrect colors

Tint in manual mode
Defective output cable
RGB cables are swapped
Check projector/monitor termination
Input source not selected correctly
No burst on input
RGB or Y,R-Y, B-Y Inputs not terminated.

Picture washed out

Composite input not terminated

NOTE:

To make sure that an input source is not the cause of a problem for a composite source, turn the

termination switch off and connect a composite monitor to the composite input Loop input. For a R,G,B
input source, turn the three termination switches off and connect a R,G,B monitor to the R,G,B input Loop
input.

To make sure that a projector is not the cause of a problem, connect a 40KHz multisync monitor to the 
15pin output connector and check the display to see if it is correct or if the monitor display shows the same 
problem as the projector display, then the VP301 has a problem and you should contact our Technical
Support Department.
