well I called Bob Roberts, and he didn't know to much
about monitors or the eygo monitor that I have.
he send me to Claudia Chen she handels all the oversea stuff,
still no help, they told me that they don't have any of the part I need,
so I got a pcb control board to another monitor to see if I can ues it for parts.
I had to pay $30 for the parts and $30 to send it, got it in one week.
it came fast,well I don't know to much about pcb control boards.

and one, 20k dc knob. or a control board for 19" eygo monitor
