Command Overview We provide an overview of the nuclei and their numbers. Never try to align the DVD-Module!

fatasheet There is no standby mode at module level. Terms of Sale Terms of Use. Alignments No alignments necessary 9. It hinges in the bracket at the side of the tilt-motor. M Main Menu 1. Careless handling during repair can reduce life drastically. Please refer to the service manual of the set for the nucleus overview of Digital Board Chrysalis.

Alphabetized Parts Part numbers based on the root B, page 61 of The digital codes are then applied to logic circuitry to obtain the various control signals. Ba538fm views added in chapter 4 3. Brands Line Card Manufacturers. This access system consists of two parts, namely the actuator and the sled, which are within a certain range mechanically and electrically independent. Electrical Socket Relay Sockets Semiconductor: More parts based on the root B: Disconnect the remaining cables tray- and fan-motor cable at the solder side of the PWB 4.

Spare Parts List Nuclei Error Codes 5. Safety Instructions, Warnings and Notes 2. Most measurements are digital measurements. Table Table of derived supply voltages.

It corrects asymmetry, performs noise filtering and equalisation, and finally recovers the bit clock and data from the channel using a digital PLL. A normal DC motor is used, combined with hall sensors. Driver Servo Board This means that the player hangs. Always place something soft a towel or foam cushion under it.

This will guarantee an optimal playability for all kind of discs. Avoid direct exposure to beam. No part of this publication may be reproduced, stored in a retrieval system or datasheef, in any form or by any means, electronic, mechanical, photocopying, or otherwise without the prior permission of Philips. It consists of three phases: The supplies can be delivered separately to obtain maximum output performance of the TZA in environments with large and highly dynamic current flows.

This is only done when datashete result of the self-test contains no errors. The commands that can be given are the numbers of the nuclei. Some of them are needed to adjust the servo error signals once per disc rotation.

EN 51 EN datasjeet Hold the sledge motor in its position by controlling the voltage on the motor continuously. Optical Pickup Unit 5. The conversion frequency is 88KHz per channel. Contact us to buy or sell excess electronic component parts and inventory. Despite of this, it is designed in such a way, that repair on component level still is possible.

The servo front-end The servo processor handles the signals for ba9538fm, tracking, and access, but also generates the control signals for the loader block. This number is the input of datazheet command mode. Reset Error LogSpindle Motor The writing clock as obtained from this groove is very accurate.

The walls of the groove are modulated in a consistent sinusoidal pattern, so that a drive can read and compare it to dagasheet oscillator for precise rotation of the disc.

Disk motor and hall elements: The following text will appear on the screen of the terminal program: Disconnect the 2-wire fan cable from the PWB. When after a while, the radial actuator drifts away, the capture point crawls a bit further on the hall sine.

Remove the four screws [3] with a Torx 6 screwdriver, and lift the DVD-M upwards [4] at the side of the disc-motor. Make sure that, during repair, you are at the same potential as the mass of the set by a wristband with resistance.

The spindle-motor interface provides both motor control signals from the demodulator and, in addition, contains a tachometer loop that accepts tachometer pulses from the motor unit. Parts list adepted in chapter 10
