Installation Videos🕸

Note: You will need to trim the four grommets that hold the original screen. Do not remove these completely. Do this as a last step when fitting everything together so you can trim them to exact size for your Lynx.

Wiring Connections🕸

Connect the pad from the BennVenn LCD driver board (left) to the Lynx 1 motherboard (right).

Garbled Image Fix🕸

There have been some reports of an unstable image after installing this kit as per instruction above. If you are getting an unstable or garbled image, implement the fix as per the wiring instructions below. The fix is to shift CLKA2 and CLKA3 left one pin as per the photos i.e. The standard wiring is to have the A2 and A3 signals connected to pads 38 and 60 on the Lynx 1 motherboard, respectively - connect these to pads 37 and 59 instead.

Alternative wiring shown in a working configuration, no garbage on screen.
