Hi guys, just as the title says, one of my PC DVD drives will not open fully after pressing the open/close button. The drive is a Sony DW-Q28A. It works fine other than the tray not opening completely. It opens about 90%, but then the drive closes it again after a couple seconds. If I pull it manually the missing 10%, then it stays open, and it will close completely when pushing the open/close button. I think I know what you are thinking: "the rubber belt is damaged, get a replacement". There's the issue: this drive does not have any rubber belt, it's all gears inside, so the usual fixes do not apply. I already disassembled the drive, cleaned the gears, added a bit of white silicone grease to the rails, but nothing helps. I also replaced the open/close motor with another exact one taken from a different drive, same problem. Any ideas? maybe these electric motors lose torque/power over time? adding the motor a drop of sewing machine oil may help? or will it damage it? Thanks for any help.
