Precautions1. ESD Precautions in Repairing1.1 Do not apply excessive pressure on the mechanical parts (moving parts), including the Pickup Block, as extremely high mechanical precision or required in these parts.1.2 When soldering the microprocessor and signal processing ICs, use a ceramic soldering iron or a soldering iron whose metal part is grounded since they are not resistant to static electricity. 1.3 When removing the solder or soldering the laser shorting lands for the Pickup Block, use a ceramic soldering iron or a soldering iron whose metal part is grounded since the laser diode or not resistant to static electricity.2. DVD Loading Unit Precautions when handling the Mechanism Block2.1 Do not loosen any screws in the Pickup Block.DVD - DivX Player - BSA375042.2 Do not adjust any screws in the Mechanism Block except for “Tilt Adjust Screws”, as they are adjusted precisely at the factory.2.3 Replacement of the Pickup Block is impossible. Always replace the Traverse Assy when the Pickup Block needed to be replaced. Do not touch the lens or lens holder of the Pickup Block.2.4 The Guide Rails of the Pickup Block are greased. Take care when handing.2.5 When you try to slide the Pickup Block, do not press or pull it directly. Always turn the dive gears with your fingers.2.6 Be sure that the anti-slipping rubber on the turntable or clean. If there is dust or it is greasy, clean the part with the liquid that contains 50% each of alcohol and water.When removing the Mechanism P.C.B. Assy, you need to short-circuit the laser diode shorting lands beforehand.
