Safety Instructions, Warnings, and Notes

2. Safety Instructions, Warnings, and Notes

2.1 Safety Instructions

2.1.1 General Safety

Safety regulations require that during a repair:

• Connect the unit to the mains via an isolation transformer.

• Replace safety components, indicated by the symbol ,

only by components identical to the original ones. Any other component substitution (other than original type) may increase risk of fire or electrical shock hazard.

Safety regulations require that after a repair, you must return the unit in its original condition. Pay, in particular, attention to the following points:

• Route the wires/cables correctly, and fix them with the mounted cable clamps.

• Check the insulation of the mains lead for external damage.

• Check the electrical DC resistance between the mains plug and the secondary side:

1. Unplug the mains cord, and connect a wire between

the two pins of the mains plug.

2. Set the mains switch to the 'on' position (keep the

mains cord unplugged!).

3. Measure the resistance value between the mains plug

and the front panel, controls, and chassis bottom.

4. Repair or correct unit when the resistance

measurement is less than 1 MΩ.

5. Verify this, before you return the unit to the customer/

user (ref. UL-standard no. 1492).

6. Switch the unit ‘off’, and remove the wire between the

two pins of the mains plug.

2.1.2 Laser Safety

This unit employs a laser. Only qualified service personnel may remove the cover, or attempt to service this device (due to possible eye injury).

2.2 Warnings

2.2.1 General

• All ICs and many other semiconductors are susceptible to

electrostatic discharges (ESD, "). Careless handling during repair can reduce life drastically. Make sure that, during repair, you are at the same potential as the mass of the set by a wristband with resistance. Keep components and tools at this same potential. Available ESD protection equipment: – Complete kit ESD3 (small tablemat, wristband,

connection box, extension cable and earth cable) 4822 310 10671.

– Wristband tester 4822 344 13999.

• Be careful during measurements in the live voltage section.

The primary side of the power supply (pos. 1005), including the heatsink, carries live mains voltage when you connect the player to the mains (even when the player is 'off'!). It is possible to touch copper tracks and/or components in this unshielded primary area, when you service the player. Service personnel must take precautions to prevent touching this area or components in this area. A 'lightning stroke' and a stripe-marked printing on the printed wiring board, indicate the primary side of the power supply.

• Never replace modules, or components, while the unit is ‘on’.

2.2.2 Laser

• The use of optical instruments with this product, will increase eye hazard.

• Only qualified service personnel may remove the cover or attempt to service this device, due to possible eye injury.

• Repair handling should take place as much as possible with a disc loaded inside the player.

• Text below is placed inside the unit, on the laser cover shield:

5. If SD4.00 mechanical construction is as in Figure 4-1,

remove screw 0010 and 0011 before executing from step 2 and 4.

Note: Flex cables are very fragile,care should be taken during dismounting and when mounting,ensure that Flex cables are inserted properly into the Flex socket and locked.

4.1.2 Opening of Tray Manually

Figure 4-4

It is possible to open the tray manually by moving the Slider in the position as shown in Figure 4-4 When the slider A is not accessible when a disc is loaded, unlock the tray by pressing the slider B inward as shown in Figure 4-5.The Tray is now disengaged and can be pulled outwards.

When no disc is loaded, unlocking the Tray can also be done by moving the Slider A in the direction as shown in Figure 4-6 and pull the Tray outwards.

4.2 Service Hints

4.2.1 DVD Module

This module can be repaired as follows:

1. The VAL6013/01 is a combination of loading mechanism and DVD-mechanism. Both the mechanism is not a repairable unit and in case of failure it has to be replaced with a new loader VAL6013/01.

Note: When replacing with a new VAL6013/01 two solder joints have to be removed after connecting the OPU flex foil to the board. The solder joints which shortcircuits the laser diodes to ground are for protection against ESD. Refer to Figure 4-6 and Figure 4-7 for location of solder points.

5.1 General

• Impedance of measuring-equipment should be > 1MΩ.

• Most tests have to be done by software commands.

Together with the software command you will find a Ref.# nbr. This is the number of the diagnostic nulceus used for this test. More detailed information can be find in the chapter “Diagnostic Nuclei”.

• Levels: Most measurements are digital measurements. The signal levels specification in this document are defined as follows: low: < 0.3V high: > 3.0V LOW: < 0.4V HIGH: > 4.5V

• All the waveforms measurement carried out in these test instruction will be base on the testpoint indicated in the Monoboard schematic diagram in the service manual.

NB rising edge should be at least 50msec after the +3V3DB (refer to Figure 5-1). If the reset input does not go high then check the reset circuit around transistor 7605.

5.2.3 Clock Check

To check the correct functioning of the STI5580, we first have to check the presence of all clocks. All clocks to be measured with 0.02% tolerance.

290102

The module operates in power-off and power-on only. There is no standby mode at module level. In power-off, the module does not response to any communication or signals. Before starting the measurement, ensure that all power supply are connected to the monoboard via connector 1701 and that the PC interface cable is connected to the Service interface connector 1501 of the monoboard.

5.2.2 Reset Check:

To ensure a proper start-up of the monoboard, the back-end reset signal RTNB is required at the STi5580 input (testpoint F906) after power-on. To check the reset timing, measure the RSTNB (testpoint F906) and the +3V3 supply (testpoint F724), reset circuit trigger signal.

5.3 µP Environment:

5.3.1 General:

All the tests are carried out by software tests. To start the software tests, connect a PC to the serial bus of the STI5580. Use connector 1501 for this connection:

Connector pin Signal

1501-1 TXT_SER (STi5580 out) 1501-2 SERVICE-mode select 1501-3 RXD_SER (STi5580 in) 1501-4 RTS_SER (Not in use) 1501-5 GND 1501-6 CTS_SER (Not in use) 1501-7 +5V_SER

Now start the terminal program. Make sure that the service-pin (pin 1501-2) of the µP is pulled low. The terminal program of your PC should now display: “DVDv4 Diagnostic software version ...”. This message already means that the µP is running. The first 5 commands from the diagnostic software will be carried out automatically during diagnostic start-up. The other commands can be carried out by selecting the “command input” and simply type the reference nbr. to do the test or select the “Menu - driven” test. To be sure that the µP is able to run the diagnostic software, serial port will be checked during start-up.

To switch the audio signal OFF, press the STOP button on the front. Without A/V board, the switching levels are as follows: – PCMDATA1 to PCMDATA3 only between low and high for

pink noise. For sine, this is low.

– PCMDATA0, PCMLRCLK, PCMCLK and PCMSCLK

switches between low and high for both pink noise and sine.

– SPDIF switches between LOW and HIGH

Alternatively, there is a check that can be done without A/V board. First, let the decoder generate pink noise on the audio outputs.

5.5.2 Slow Blanking Scart

An aditional part of the video-path is the scart functionswitching test. The scart function-switching pin has three levels which depend on the level of the output ports SCART0 and SCART1. These latter two signals are driven by the output pins PIO3.6 and PIO3.7 of the STi5580.
