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.

Re: Ricoh mpc 2800 sc672

thanks for info, really interesting to know,a tech here suggested the touch screen is faulty, could it be ??? as no buttons are functioning,is it the initialization process that when it comes to the display section it stops ???Thanks all for your support

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.

Re: Ricoh mpc 2800 sc672

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.

Re: Ricoh mpc 2800 sc672

Re: Ricoh mpc 2800 sc672

thank you once again, i have checked cables 3 times now all looks in place..

LOOKS?

did you disconnect the re-connect just because something LOOKS connected doesn't mean they ARE connected properly.. you COULD have a bent pin in the connector

pull the damn harnesses and reconnect

Re: Ricoh mpc 2800 sc672

Thanks , as soon after it made an error , the sc202 was not visible as the LCD was not lit (was dark), we replaced the fuse on the board Bicu the display lcd light came on and we could read the error, replacing the mirror motor now we are getting SC 652.checked all connectors to controller all seems ok. OLD mirror motor had 2 components burnt.

What fuse did you replace on the BICU?
