BOSE SoundTouch Wireless Adapter – air play and non air play – WiFi module test - factory reset - USB port test - disassembling – teat procedure

BOSE SoundTouch Wireless Adapter DISASSEMBLY PROCEDURES

1. Top Cover Removal
1.1 With the unit upside down, remove the three screws that secure to two halves of the enclosure together.
1.2 Lift off the bottom enclosure. It will come off with the Wi-Fi PCB assembly mounted in the bottom of it, attached to the I/O board with two ribbon cables. The I/O PCB assembly is mounted to the upper enclosure plastic.

2. I/O PCB Assembly Removal

2.1 Perform procedure 1.
2.2 Remove the two screws that secure the I/O PCB assembly to the upper housing. Lift out the board.
Note: Retain the connector scrim and the reset button scrim for re-use.
2.3 Disconnect the Bose link cable at J201. Disconnect the ribbon cables and J200 and J300.
Note: The Bose link cable is not easily replaceable. It comes as a service part, included with the top housing, pressed in place.

3. Wi-Fi Module PCB Removal
3.1 Perform procedure 1.
3.2 Remove the one screw that secures the Wi-Fi board to the bottom housing. Lift out the PCB assembly.
3.3 Disconnect the two ribbon cables at J1201 and J1203.
Note: Due to complexity, the Wi-Fi module PCB assembly is not repairable at the component level. If you suspect it has failed, you will need to replace the board.

TAP COMMAND SETUP

Note: The SoundTouch wireless adapter is powered by +12 over its Bose link cable. You will need to connect the wireless adapter to a compatible SoundTouch product such as an SA-4 amplifier, Stereo JC music system bass module or a Lifestyle SoundTouch media center in order to provide power to it for the following tests.
TAP command setup
Equipment Required:
Hardware
# Computer w/serial port
# RS232 to TTL converter
# Lifestyle ETAP Cable, P/N 264565
# SoundTouch product, SA-4 amplifier or other compatible
Software
# TeraTerm terminal emulator 
TAP commands are sent to the SoundTouch wireless adapter by connecting to the SERVICE connector on the back of the adapter. An ETAP cable and RS232 to TTL Converter are required for this communication. The ETAP cable is available from Bose  (see part number above). The RS232 to TTL Converter is made by B+B electronics, model number 232LPTTL. TAP commands are needed for the following procedures:

A. Wi-Fi Test
B. Serial Number Programing
C. Setting Wi-Fi Country Code
1. Tera Term Terminal USB Setup
Tera Term is a terminal emulator and can be downloaded at sourceforge  projects/ttssh2/. It is the interface used to send TAP commands to the SoundTouch wireless adapter.
1.1 Connect the SoundTouch wireless adapter to the computer.
# Connect the RS-232 to TTL converter to the COM port on the PC. 
# Connect the TAP cable to the RS-232 to TTL converter.
# Plug the other end of the TAP cable into the SERVICE jack on the back of the SoundTouch wireless adapter.
# Connect the SoundTouch wireless adapter Bose link cable to the SoundTouch product.
# Connect the SoundTouch product to AC power.

The chassis in this receiver is partially hot. Use an isolation transformer between the line cord plug and power receptacle, when servicing this chassis.
To prevent electric shock, do not remove cover. No user-serviceable parts inside.

It is important that the static charge is removed from the high voltage system when carrying out work on the receiver. This can be achieved by connecting a 10K resistor (with a suitably insulated lead) from the CRT cavity connector to the CRT ground tag. This must be carried out with the AC supply disconnected from the receiver.

This receiver is designed to keep any x-ray emission to an absolute minimum. Some fault conditions and servicing procedures may produce potentially hazardous x-ray radiation levels. This is a problem when in close proximity to the receiver for long periods of time. To reduce any risks associated with this,  observe the following precautions:

1. When undertaking any servicing on this chassis, DO NOT increase the EHT to more than 30.5 KV, (at a instantaneous beam current of 1300)
2. Ensure that during normal operation the EHT does not exceed 25.0 KV +/- 1.5KV (at a beam current of 1100.) This level has been preset in the factory. Always check that this level has not been exceeded after carrying out any repair on the receiver.
3. DO NOT replace the CRT with any other type than that specified in the parts listing as this may cause excessive x-ray radiation.

White Level

Set the brightness control, with no signal connected, so that the CRT cathode current is 600mA. The maximum correction applied to each cathode current to achieve a screen temperature of 8900 degrees K-20 MPCD should not exceed 15% of its original value.

LED flashing code

The led indicates the power mode, occurred I2C error and On timer

- Current power mode
- I2C Errors
- On timer

If in STANDBY mode and ON timer in-active then switch LED off.
- If in STANDBY and ON timer active set LED to blinking, (switch on and off at 1 Hz with a 50 % duty cycle).
- If in POWER-ON mode, switch LED on.
- If an I2C error occurred, let the LED blink at 1 Hz, 50 % duty cycle.
For the blinking times see the Table below.

Only when an I2C error occurs for a number of times, or for a number of seconds, the I2C error is handled by the system (that is ,only then the set will go to standby, the led starts blinking).

PIN configuration of TDA935X- [SDIP64]

Information:TDA9381 (IC801)

The function of pin 20, 28, 29, 31, 32, 35 and 44 is dependent on the IC version (mono intercarrier FM demodulator / QSS IF amplifier and East-West output or not) and on some software control bits.

The vertical guard function can be controlled via pin 49 or pin 50. The selection is made by means of the IVG bit in sub-address 2BH.

When additional (external) selectivity is required for FM-PLL system pin 32 can be used as sound IF input. This function is selected by means of SIF bit in sub-address 28H.

The reference output signal is only available for the CMB1/CMB0 setting of 0/1. For the other settings this pin is a switch output.
