REPAIRING AND NOT THROWING AWAY

Richtige Fernseher haben Röhren!

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.

TRACE
A new TV Repair Assistance Tool that combines ease of use and powerful PC software tools to allow you to save valuable time during many TV repairs.
The TRACE interface connects to the PC's serial port. It provides connection to the TV's I2C bus and can be provided with an Infra Red transmitter (optional).

The interface is powered by a standard 9 V PP3 battery for portable use, and can also be powered by an external 9V/25mA DC power supply.
The TRACE software that is supplied with the interface allows you to:
  • Read, restore and compare NVM contents via the I2C bus
  • Acknowledge check of all I2C devices in the TV set
  • Read Error Codes (emulation of the Error Reader tool)
With the optional IR Add-on kit, the following features can be added:
  • Remote Commander emulation
  • User programmable Functional Check through Infrared
  • Fast and documented Test Mode setting of all Sony TV chassis.
Additional features such as Adjustments and Troubleshooting are available in chassis-dependent software modules. Please contact your local Sony Service organization for the latest information.
Note: For workshops already using the existing I2C Link parallel port interface (9-948-320-30), this software can be used as well, replacing the
TV Data Handling software (9-948-340-50), but Error Reader and IR functions can only be accessed with the TRACE interface.
Partnumbers: TRACE Starter Kit (TRACE interface + software): 9-948-320-70
TRACE Software (for users of the I2C Link interface): 9-948-340-80
TRACE IR Add-on (IR interface + Remote Commander software): 9-948-320-80
PC requirements: IBM-compatible PC with operating system Windows95, Windows98, or WindowsNT*.
