The 2005 models use DVD drives VXY1867 or VXY1872 with the large black plastic case with three ribbon cables connected to an onboard controller PCB and from that PCB there is a single ribbon cable to the separate Digital PCB. The VXY1872 DVD Drive is used with HDD/DVD models.
The 2006 models use DVD drives VXY1916, VXY1972, VXY1945, VXY1956 or a "no model number" DVD Drive with DMR-ES15 and DMR-ES25 DVD Recorders. These DVD Drives have four ribbon cables connected directly to the separate Digital PCB. The VXY1945 and VXY1956 DVD Drives are used with HDD/DVD models.
The 2007 models use DVD drive VXY1961 with the four ribbon cables connected to the onboard controller PCB and from that PCB there is a single ribbon cable connected to the separate Digital PCB.
The 2008/2009/2010 models use DVD drive VXY2010 with the four ribbon cables connected to the onboard controller PCB and from that PCB there is a single ribbon cable connected to the separate Digital PCB.
Panasonic’s 2006 model year DVD drives are powered through a ribbon cable instead of a wired connection as found on 2005, 2007 and 2008/2009/2010 model year DVD drives.
The 2006 DVD drives I’ve examined are paired with the Digital PCB VEP79132. That PCB stores the DVD drive alignment data, including error codes/history, accumulated "working time," even the "laser used time (hours)," of the DVD drive with which it has been paired. These Digital PCBs are factory configured for use with specific recorder models so there is limited interchangability.
Panasonic repeatedly cautions that 2006 model DVD drives and the separate Digital PCB must be replaced together as a “module,” and if not replaced together, the "module" requires "realignment" as the DVD drive alignment data is stored on the Digital PCB.
As mentioned in earlier posts I have successfully swapped 2006 model year DVD drives between different 2006 DVD recorder models. When swapping 2006 model year DVD Drives between different models I’ve usually retained a recorder’s original Digital PCB. In one instance I swapped a DMR-ES46V Digital PCB into a DMR-ES35V. That DMR-ES35V has had normal functionality since the swap. One 2006 DVD drive, pulled from a DMR-ES35V parts machine, subsequently gave nine months’ satisfactory service in a DMR-ES15 until that DVD drive’s laser assembly failed. Another 2006 DVD drive, originally from another DMR-ES35V parts machine, was swapped in. That DMR-ES15 has had normal functionality since the swap.
Panasonic's 2005, 2007 and 2008/2009 DVD drives have onboard PCBs that store the drive alignment data so the separate Digital PCB does not need to be paired with a specific DVD drive.
While 2007 and 2008/2009 DVD drives are similar in appearance these DVD drives have different model numbers. Wilmorr reports a successful swap of a good 2008/2009 VXY2010 DVD Drive fitted with the on-board controller PCB from a 2007 DMR-EZ17 where the VXY1961 DVD Drive has a failed laser assembly. This confirms that 2007-2010 model year DVD Drives will interchange as long as the on-board controller PCB is also swapped between the DVD Drives.
Those swapping DVD Drive controller PCBs should notice that the ribbon cable connector for the laser assembly data ribbon cable has a flip-up locking/unlocking mechanism. Three of the ribbon cables have their grip-tabs facing outward whereas the copper colored ribbon cable has its grip-tab facing inward.
The several posts that follow have attached photos showing two models of 2005 DVD drives and the onboard controller PCB; two models of 2006 DVD drives and the separate Digital PCB; a 2007 DVD drive, the onboard PCB and the separate Digital PCB; and a 2008/2009/2010 DVD drive, the onboard PCB and the separate Digital PCB. Notice the variations in ribbon cable arrangement between the various model years and the wired power connection utilized with 2005, 2007 and 2008/2009 model year DVD drives.
