The last line allows the user to choose between the three possible interface forms. The electronics of ba59938fm module is responsible for all basic servo tasks.

Disk motor and hall elements: This part describes the command and menu interface. Set the mains switch to the ‘on’ position keep the mains cord unplugged!

Progressive Scan Board 7. Sledge motor and hall output: The other loops determine the laser spot position on the disc in the radial, axial focus datashset, and tangential directions.

Remove the clamp assy, by releasing the two side clamps [2] while moving it upwards. See also ba5938mf internal block diagram at the end of this chapter. M Main Menu 1.

Get Self Test Result 9. It corrects asymmetry, performs noise filtering and equalisation, and finally recovers the bit clock and data from the channel using a digital PLL. Never try to align the DVD-Module! Repair handling should take dtasheet as much as possible datasgeet a disc loaded inside the player. Keep components and tools at this same potential. Power Transistors RF Transistor. Now you can access the DVD-Module. The easiest way to do this is to push down the two fixation pins of the clamp via the holes in the PWB by means of a pencil or small screwdriver.

Service personnel must take precautions to prevent touching this area or components in this area. This is the number of the diagnostic datahseet used for this test. In power ‘off’, the module does not respond to any communication or signal. In b5a938fm to let the sledge move even faster the ratio of the gearing can be reduced.

Electrical Socket Relay Sockets Semiconductor: A ‘lightning stroke’ and a stripe-marked printing on the printed wiring board, indicate the primary side of the power supply.

Safety Instructions, Warnings and Notes 2. Disconnect the four flex foils from the PWB connectors,and at the component side. Driver Diagram 3 34 Servo Board The writing clock as obtained from this groove is very accurate. It also adjusts offsets, signal amplitudes, and loop gains AGCsto enlarge system robustness and to avoid expensive potentiometer adjustments in production. Detailed diagnostics and fault finding is possible via ComPair.

Mesh the teeth of the sledge motor and sledge rack properly, during mounting of the sledgemotor assy. The application can react on this with a shock recovery procedure. It contains logic for: Consignment and warehousing available.

You can replace it now. Among the DVD family of formats, only recordable media use wobble grooves. The walls of the groove are modulated in a consistent sinusoidal pattern, so that a drive can read and compare it to an oscillator for precise rotation of the disc. Now you can remove the board.
