Console Main PCB troubleshooting Disassembly Remove the top cover of the console using Console Disassembly/Assembly procedure 1. Use the other disassembly/assembly procedures to remove the CD/DVD mechanism. Once that is out of the way, remove the casting over the main PCB. You will need to remove the clip on the amplifier IC and to pry the amplifier IC slightly away from the heatsink before you can remove the casting. Make sure that the LCD display board is still connected for troubleshooting. You will be able to power up and troubleshoot the board while it is still in the console base with the casting and heatsink removed. Do not connect the 9 pin speaker array cable to J150. Make sure the console volume level is all the way down so that the amplifier IC U150 does not overheat when operated with no heatsink on it. Test Cables Cable Extenders In order to troubleshoot the main PCB in the console with the CD/DVD mechanism connected, you will need an extender 40 pin ATAPI cable and an extender computer power supply cable. Parts needed: 15 pin female subminiature D connector DC power supply 4 ft of red AWG 18 wire 4 ft of black AWG 18 wire 1. Twist the black and red wires together to make a twisted pair. This is to help prevent coupling noise into the console. Strip about 1/4" of insulation from one end of each of the wires. 2. On the rear of the 15 pin D-sub connector, solder the red wire to pin 7 and the black wire to pin 2. Refer to the figure below.

Both of these parts are readily available at any computer or electronics parts store. Extending these cables will allow you to use the CD/DVD drive to provide a video signal while you signal trace on the main PCB with the casting removed. Plug the one end of the longer ATAPI cable into the main PCB. Plug the other end of the ATAPI cable into the back of the CD/DVD mechanism. Be sure to observe pin 1 polarity. Refer to Figure 9. Plug one end of the extender power supply cable into the console power supply cable. Plug the other end of the power supply cable into the power connector on the back of the CD/DVD mechanism. Note: The 3-2-1 console will not power up without the DVD drive connected. Console Power cable You can power up the 3-2-1 system console without the need for a bass module by making up a simple cable and using a DC power supply. The supply must be capable of putting out +15Vdc at approximately 3A.

3. Strip about 1/2" of insulation from the other end both wires. Connect the red wire to the positive terminal and the black wire to the ground terminal of the DC power supply. 4. Plug the 15 pin D-sub connector into the rear panel of the 3-2-1 system console. 5. Turn on the DC power supply, and set the output voltage for +15Vdc. You can now power up the 3-2-1 system console without the need for a bass module. Bass Module Test cable You will need to be able to check the output of the bass module's power supply circuitry, as well as to input an analog audio signal to check the bass module operation. You can do this by making a simple test cable. Note: The bass module will not un-mute without +5 Vdc on the /MUTE line at pin 13. Parts needed: 1 male 15 pin subminiature D connector with solder terminals 1 10k Ohm, 1/4 Watt resistor 1 5k Ohm, 1/4 Watt resistor 1 ft of red AWG 18 wire 6 inches of black AWG 18 wire 4 ft of green AWG 18 wire 4 ft of yellow AWG 18 wire 6 inches of white AWG 18 wire 1. Twist the yellow and green wires together to make a twisted pair. This is to help prevent coupling noise into the console. Strip about 1/4" of insulation from one end of each of the wires. Strip about 1/2" of insulation from the other end of the wires. 2. On the rear of the 15 pin D-sub connector, solder the yellow wire to pin 6 and the green wire to pin 3. The yellow wire at pin 6 is the bass audio + input. The green wire at 3 is the PGND connection. Refer to the following figures.

Figure 14. Bass Module Test Cable Wiring 3. Strip about 1/4" of insulation from one end of each of the red and black wires and about 1/2" from the other ends. On the rear of the 15 pin D-sub connector, solder the red wire to pin 7 and the black wire to pin 2. The red wire at pin 7 is the +15V coming out of the bass module power supply. This voltage is also present on this connector at pins 8, 14 and 15. Be careful to not short the +15V to anything when testing. The black wire at pin 2 is connected to PGND. Pins 4, 9, 10 and 11 are also tied to PGND. 4. Twist one end of the leads of the 10k and 5k resistors together to put them in series. Solder one end of the white wire to the the point between the two resistors. Solder the other end of the white wire to pin 13 on the 15 pin D-Sub connector. This pin is where the +5 Vdc /MUTE input signal that normally comes from the 3-2-1 console to un-mute the bass module audio amplifier IC U1 is brought in. The bass module will not un-mute without this DC voltage level. Solder the other end of the 10k resistor to pin 15 of the D-Sub connector. Solder the other end of the 5k resistor to pin 11 of the 15 pin D-Sub connector. 66

Figure 15. Tap Interface cable wiring diagram
1. Cut off one end of the PC null modem cable. You will need only the three wires that correspond to pin 2, pin 3 and pin 5 of the 9 pin D-SUB connector. 2. Mount the three wires with the pre-crimped JST terminals into the JST connector as shown in Figure 10. The red wire goes to pin 1, the white to pin 2 and the green to pin 3. Be sure to check that the wire locations are correct or your cable will not work. 3. Once the wires are installed, place a piece of heat shrink tubing over the three wires approximately 1/8" behind the JST connector and heat shrink it in place. This is to help keep the wires secured in the connector. Now place a two inch long piece of heat shrink tubing over the other piece and just over the shoulder of the JST connector. Heat shrink this in place as well. This tubing will provide a convenient means of cable insertion and removal in the 3-2-1 console connector.

Computer Setup Procedure (continued) 4. In the properties dialog box, click on the SETTINGS tab and set the controls as shown in the example at right. Note: Be sure to check "Beep three times when connecting or disconnecting".
Preliminary
5. In the properties dialog box under the SETTINGS tab, click on the ASCII Setup button and set the controls to look like the example at right. Click OK to return to the properties dialog box.
6. Once you have made all of the settings in the properties dialog box, click OK to close it. You have now configured your PC to communicate with the 3-2-1 system console. To connect to the console under test, in the terminal window, click on CALL, then CONNECT and listen for 3 beeps. This will tell you that the PC is connected to communicate with the console. When you have completed your session, click on CALL, then DISCONNECT to end communication with the console. 69
APPENDIX
Console TAP Commands The 3-2-1 console can be controlled by means of test access port (TAP) commands via a TAP cable from one of the computer's serial data ports to the TAP port located on the LCD display PCB. This port can be accessed from the outside of the console without disassembling the unit. You will need the TAP cable and a RS-232 to TTL converter, such as the B+B electronics model 232LPTTL. You can purchase the converter online at http://www.bb-elec.com. Refer to the TAP cable fabrication instructions earlier in the appendix for a wiring diagram of the TAP cable. The communication link for the TAP facility is: Via a three wire TTL electrical interface (Transmit data, Receive data, Ground). Logically inverted receive and transmit signals from RS-232 specification. Same asynchronous character / timing construction as RS-232 specification requires. The computer serial data port used for communication should be configured as follows: Half-Duplex operation 9600 baud 8-bits / data character 1 stop bit No parity The console echoes all commands Refer to the computer setup procedure earlier in this section for instructions. There is no special action required to put the 3-2-1 console into TAP mode. Once power is applied TAP control may be used. The 3-2-1 console does not respond to multiple commands simultaneously. The user must receive an acknowledgement (ack) prior to issuing the next TAP command. The following tables list the TAP commands broken down into the various sub-sections of console functions.
