This means the analog inputs are not getting analog signal updates (potentiometers).
Check your wiring, perhaps something is shorting your sensors to the Ground.
Do you have a sensor to connect on one of the ports to see if you read values?
Thanks Thanos

Still nothing ..... and the old board is showing the right side even with nothing connected ..... I do have extra sensors and i connected one and still nothing ....

The only mode that has disabled sensors is the clearpath Burst mode. Make sure that this mode is disabled like in the next photo. Thanks Thanos

Ok i tried that. i disabled the CLP and they did come back, but disappeared again once i changed the screen. Now when i reset or power cycle the board, they appear but as soon as i change something on the screen, they disappear

Sorry just to clarify, you just turn the AREF knob CLOCKWISE and all is ok now? What is the problem with the power supply then? Thanks

The power supply issues was that i was powering the amc board only from usb with is 5 volts but the arduino needs 7 to 12 volts to operate correctly. so i attached a 12 volt power supply and its operation was significantly better. Now i just need to figure out the aref sweet spot as it likes to dance around allot ... thanks

Hmm.. 5v from the USB should be enouph for the AMC1280USB. I assume the sink mode is leaking some power from the board to the vfd inverters, thus the reason you had voltage drop. Using external power supply just allows the leak to draw the current it needs without affecting the microcontroller voltage much.
