Troubleshooting
1. If the green LED is not on:
a. Is the receiver correctly positioned in the slot? Are the screws tightened?
b. Is the display turned on?
2. If the LED is on, but there is no picture:
a. Have you selected "Option" as input?
b. Although it is unlikely, please check to see if the dip switches in the back of the unit (behind the black 60-pin connector) are
in the correct position. The dipswitches on the unit must be set as follows:
Position 1 2 3 4
State Off Off On On
3. If the picture is out of focus:
a. Has the correct resolution been set?
- NEC MultiSync® LCD4020, LCD4620: 1360 x 768
- NEC M40, M46 and MultiSync LDC5220, LCD6520, L&P: 1920 x 1080
b. The display has possibly been set up for a different size. Press the “Size“ button on the remote control until “standard“ is
displayed in green in the top right-hand side of the screen.
c. Has the unit been tuned properly? [See “Operating and Maintaining Instructions / Tuning]
