Sensor PCB for DMR E75V and compatibles

Is there a reliable way to find Panasonic DMR Combo VHS/DVD sensor PCBs (the left-side small circuit board behind the on/off switch)? Parts-only devices may not have a working PCB. Mine got cracked during shipplng (which also broke the VHS door). I soldered and wired across the crack, which allows it to work only sporadically (at least without a remote control), so I would like to replace the PCB (which is very straightforward) if it can be found.
