Re: Canon IR 3230 No display

Do you mean after "switching power on" or "switching" power supply board?

It's been awhile but think no display has somewthing to do with the HDD or system software. Also think bad or missing ROM would cause this.

POSTERS PLEASE PROVIDE MORE DETAIL IF YOU WANT HELP !!!!

For me it looks like LVPS or HVPS issue.
Try minimal configuration or with opened all doors (this will cut off all bigger electrical circuits). Better is to remove fuser, ITB, drums, devs.
This way you eliminate any short circuit in consumables or grounding problem.

Nothing happens with minimum circuits connected no fuser no drawer no develper unit no adf connected

Re: Canon IR 3230 No display

So next step I will do is measuring a voltage on connectors. If you have a service manual you can check a correct values. Lastly, do you have any other working machine? It is possible to exchange a boards and power supplies between them. It is good practice to put suspended logic boards like main controller, drum drive into. into working machine. Opposite with a power supplies - working PS to the suspended machine.
First, Very important, do not exchange main controller with additional boards on it, like serial and counters board. Them must stay in original chassis. Second, do not exchange more than one board at same time! Change one and check the machine.
If you need and want, I will search a voltage values and connectors to check for you, but tomorrow

Checklist:

1. Is 12 V output from theMain Controller PCBJ3?
2. Is 12 V supplied to theMain Controller PCBJ22?
3. Is 12 V output from theLowVoltage Power SupplyPCB J812?
4. IS AC supplied tothe AC Driver PCB J6010?

main controller bord has only 3.5v supply in
no 12v in controller board

sorry my mistake, I saw wrong manual I try to obtain a correct one or Deepaklohmi maybe you have and could check?

Re: Canon IR 3230 No display

sorry, manual for this machine is not reachable for me... that's why I mistaken with another one with similar number ;/
