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.

While pressing the "INPUT" and "MENU" buttons together, press the "MAIN POWER" button to turn on the power.  (Keep pressing the "INPUT" and "MENU" buttons until a display appears.)  If "1/16" is displayed in blue characters on the screen several seconds later, the process adjustment mode has been entered. Pressing any of the cursor UP/DOWN/LEFT/RIGHT keys will display the 1st page of the process adjustment mode. If you fail to enter the process adjustment mode (the same display as in the case of normal start-up appears), repeat the above-described steps again.

PREPARATIONS
  1. Software for rewriting is provided as an executable file having a name such as "MAIN_2002_10_10A.exe" (tentative name). Create a directory with an appropriate name on the hard disc of the PC to be used for rewriting and copy the software to it.
  2. When this file is double-clicked on Windows, decompressing the compressed file is started. Carefully check if the contents of the decompressed file correspond to the documentation attached to the program.
