I have the same problem with LX1 so I would like to know the following:
Is there a way to dump both parts of firmware off this or any other Pioneer DVR-xxx drive using software or device programmer tools?
Which chip on the Pioneer DVR-xxx drive board usually contains firmware?
A tip to reparke: if only a OPU is out of order you can easily replace it with a OPU from Pioneer DVR-105 or DVR-A05. Actually Pioneer DVR-105-PLX and Pioneer DVR-105/A05 drives are absolutelly identical except for both parts of firmware. So the question is how to dump both parts of firmware?
If anyone has such an experience please write a PM. Thanks.
