Additional Laser Caution 1. � Laser diode is driving with Q2303,Q2305(650nm LD) and Q2302, Q2304(780nm LD)on the DVD MT PCB Assy. Therefore, when short-circuit between the emitter and collector of these transistors or the base voltage is supplied for transistors turn on, the laser oscillates. (failure mode) � In the test mode � , there is the mode that the laser oscillates except for the disc judgment and playback. LD ON mode in the test mode oscillates with the laser forcibly.
