I was using my 712A, firmware 1.07 and ImgBurn in burn then verify mode, when I received a Servo Tracking error (Panasonic Branded TYG02 DVD-R). The disc played fine though. To be on the safe side, I upgraded the firmware to 1.08, and once again use ImgBurn, but write only – and the job finished without any problems.
However, after that successful burn, the 712A no longer recognizes any disc I put in – the computer always says “no disc”. I tried downgrading the firmware back to 1.07, then upgrade to 1.09, but neither solved the problem. Now when I put a disc in, it just intermittently flashes orange lights, but it will not recognize anything. Is my drive dead?
Please help. Thanks in advance!
