I plugged in a 6v charger to camera , it flaged, one and doest work after that
Hi, Check if fuses FU601 & FU602 are both OK. Hopefully the DC/DC converter wasn’t affected Here’s an image taken from the service manual for the camera, showing the location and Canon part number for the fuses. If a fuse has blown search online using the part number only to find suppliers that suit you best. The manual also shows the dis-assembly procedure that will help.
