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.
