REPAIRING AND NOT THROWING AWAY

In Brief: On this site you will find pictures and technical information about Service Modes, Circuit Diagrams, Firmware Update procedure, Disassemble procedure, Universal remote control set-up codes, Troubleshooting and more....

If you go into the profession, you will obtain or have access to a variety of tech tips databases HERE IT IS Master Electronics Repair !.

These are an excellent investment where the saying: 'time-is-money' rules. However, to learn, you need to develop a general troubleshooting approach - a logical, methodical, method of narrowing down the problem. A tech tip database might suggest: 'Replace C536' for a particular symptom. This is good advice for a specific problem on one model. However, what you really want to understand is why C536 was the cause and how to pinpoint the culprit in general even if you don't have a service manual or schematic and your tech tip database doesn't have an entry for your sick TV or VCR.

While schematics are nice, you won't always have them or be able to justify the purchase for a one-of repair. Therefore, in many cases, some reverse engineering will be necessary. The time will be well spent since even if you don't see another instance of the same model in your entire lifetime, you will have learned something in the process that can be applied to other equipment problems.
As always, when you get stuck, checking out a tech-tips database may quickly identify your problem and solution.In that case, you can greatly simplify your troubleshooting or at least confirm a diagnosis before ordering parts.

Happy repairing!
Today, the West is headed for the abyss. For the ultimate fate of our disposable society is for that society itself to be disposed of. And this will happen sooner, rather than later.

Computer Setup Procedure
Use this procedure to set up your IBM compatible PC for communication with the 3•2•1 system console.
1. Open a terminal window,  in either Terminal or Hyperterm, as applicable for the version of Microsoft Windows you are using on your PC.
2. In the terminal window, click on FILE, then PROPERTIES. Set the properties in the dialog box.
3. In the properties dialog box shown in step 2, click on CONFIGURE to set the COM1 Properties Click OK to return to the properties dialog box.
Bits per second > 19200
Data bits > 8
Parity > None
Stop bits > 1
Flow control > None
4. In the properties dialog box, click on the SETTINGS tab and set the controls as shown.
[Be sure to check "Play sound when connecting or disconnecting".  2. The examples shown on the following pages are for Hyperterminal as used with Windows 2000 Professional. Your dialog box views may vary slightly depending on the version of Windows and Hyperterminal you have.]
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. Note: Be sure to click the “Send line ends with line feeds” box as shown. If you fail to check this box, the 321 II console will not communicate with the computer. Click OK to return to the properties dialog box.
6. Once you have made all of the settings in the properties dialog box, click FILE/SAVE to save your setting. Click OK to close the window. You have now configured your PC to communicate with the 3•2•1 Series II system console. To connect to the console under test, in the terminal window, click on CALL, then CALL and listen for the sound. 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.
ETAP Cable Construction and Setup
You will need to make up an ETAP cable using the diagram below. You can build this cable from a Boselink A or B cable and a DB9 connector. You don't need the RCA connectors if you don't want them. They are the Zone 1
and Zone 2 audio inputs for the console. You will also need to use the same level shifter you use for the 321 Series I for TAP. This level shifter made by B+B Electronics, model number 232LPTTL, and can be purchased online at http://www.bb-elec.com. Refer to the photo at right for an image of the converter.
ETAP Overview
A serial RS-232 interface is provided on the console for communicating with the test system.  This interface, called ETAP (Extended Test Access Port), and it uses strings of standard ASCII characters as commands. The ETAP is accessed via the expansion port (BoseLink) interface. Some of the commands will be brokered by the Main Board through to the Tuner Board for implementation, and the subsequent replies will be generated by the Tuner Board and passed via the Main Board out to the test system.
Boselink ETAP Cable Wiring Diagram
Terminal Parameters
Using an IBM compatible PC with Microsoft Windows, Open a hyperterminal window. Set up the session to communicate with the console using 19200 baud, 8 data bits, no parity, one stop bit.
Setting up console for ETAP mode
Immediately after system bootup (within 5 seconds) an ETAP command must be issued to put the console into ETAP mode. Any ETAP command can be used to set this. Note: The system must have power removed, and then re-applied in order for it to boot. Pressing the ON-OFF button on the console does not completely remove power. The Boselink input and ETAP port share the same hardware UART on the CS98200 and it must know which format to speak via the Boselink connector. If no ETAP command is issued in this time, then the console assumes that the unit is operating in a “customer environment” and switches to Smart Speaker.
