Hitachi BD-W70PV after turning off shows error "F12" and then turns on again. I can't find this error in manual because all code are "C01-C30".

Hello sir; I believe your error code should be C030, if that's correct that 's mean main board is bad , it not worthy to repaire it, go buy a new machine.

first of all check the circuit breakers to be sure one or both aren't kicked. be sure to turn the breaker all the way off and then fully on as a tripped breaker is in a halfway off position. if that doesnt fix your problem remove the access panel to the mechanical space in your tub. there are generally one or two reset buttons in there which can also kick off and need to be reset.

Changing the ink tube or the RFID chip on the ink tube may solve your problem.
