TROUBLESHOOTING
LCD Pixel Statement - The LCD unit is produced with high-precision manufacturing techniques. Nevertheless, some
pixels may occasionally misfire or appear as black or colored dots. This has no effect on the recorded image and does
not constitute a malfunction.
Normally, a 17” SXGA (1280 X 1024) display has nearly 4 million sub-pixels. Industry standard specification allows 8
non-performing pixels on the LCD screen, which is only 0.0002% of the total sub-pixels.
Troubleshooting

will be green. If it is green and there is no picture

VGA cable to the monitor and the connection to
the computer.
• “NO POWER”: Make sure the power cord is
securely connected to the adapter and the light
