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!

Inserting the Region Code after replacing the Main PCB

NOTE
• After replacing the Main PCB and System Micom (IC23), the region code should be inserted.
• The unit will not work properly if you do not insert the correct region code.
• You must use the remote control

Select the "AUX" mode and then press the "Tuner Memory" button on the remote control for 4-5 seconds

You should see the “T-MODE” message display on the VFD. Press the “▼” direction button during this message.
NOTE: The “T-MODE” indicator on the VFD only appears for a very short time.

You can see “TEST - -” on the VFD. Insert the number “46” to select the Region Code.

After step (3), you can see “- - -” on the VFD.
Insert the Region Code (see Table on next page) corresponding to the model and area in which you reside in using the “0-9” buttons on the remote control. And then turn off the power.

In order to check if you inputted correctly, please do Number 1, 2, 3 again and then during “TEST - -” MODE insert number 47. After that, you can check the option code which you inserted. For example, you can see “000US5”. It means that you inserted region code “000” and the region is USA which supports 5.1CH Audio output. If it is “047EU2”, it means that you inserted region code “047” and the region is Europe which supports 2.1ch Audio output.
