its a good point about the connectors, but i have checked them individually all 11 with a watch maker magnifier, thanks though for your suggestion, its a plus

What I am concerned is that green LED 3 on Bicu is blinking continuously , is it normal or an error indication ???

That is probably what is referred to as the heart beat indicator. It shows that the system clock is functioning. If it were orange or red it would indicate a major problem.

As for the control panel, the basic display on the LCD screen is controlled by the firmware loaded to the control panel main board. The operation of the touch screen and the buttons on the panel are controlled through communication with the controller. You press a button and that action is sent to the controller. You touch the touch screen and the X and Y coordinates of where you touched is sent to the controller. No communication with the controller, no response to what you press of touch.

Touch screen problems result in either no response or the wrong response. There is a touch screen test and adjustment section in the service manual.

You might search to see if you can buy a complete C2800 for a parts machine. Here in California we can often find them for less than a new major board costs from Ricoh.
