REPAIRING AND NOT THROWING AWAY

Richtige Fernseher haben Röhren!

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.

Dressing the antenna cables


Setting and adjustment

If the adjustment is shifted or if it becomes necessary to readjust because of part replacement, etc., perform the adjustment as described below.
• Any value changed in Adjustment mode will be stored in memory as soon as it is changed. Before readjustment, take note of the original values for reference in case you need to restore the original settings.
• Use a stable AC power supply.

Adjustment required when the unit is repaired or replaced


USB backup and Updating the Firmware

USB backup

This model is capable of saving the set values stored in the MAIN Ucom of DMAIN Assy in the USB and loading them in a new DMAIN Assy. (Note that MAIN Ucom should normally operate to enable this function.)
When replacing DMAIN Assy, execute the above mentioned processes


Requirements for USB memory
USB memory to be used should meet the following requirements.
• Compatible with USB Mass storage Class
• With a file system of FAT (FAT32)
File saving format
Files are to be saved in the following format:
Example: VSX-1130_BK01.avr
How to save in the USB memory from AV amplifier
1. Insert the usable USB memory into the USB terminal when the main device is off.
2. Enter the SERVICE MODE and select [USB BAK c HOLD d] with g keys.  [See  TEST MODE] for how to enter the SERVICE MODE.)
3. Select [USB BAK c SAVE? d ] with h keys and press [ENTER].
Note: The system cannot execute SAVE, LOAD until start is completed of Network module.
4. Saving in the USB starts and the main device automatically goes off after the normal completion ([COMPLETE] is displayed.).
5. Remove the USB and saving is finished.
*1. If the following errors occur after "SAVE" is executed, error message will be displayed and "SAVE" will be stopped and the power will be turned off.
• Ejecting of USB device
• Short capacity of USB device
• Error during writing in the USB device (Read Only or defective Sector, etc.)
*2. If the same file name exists in the USB, overwriting will be automatically executed.
How to write into AV amplifier from the USB memory
1. Insert the USB with the saved file into the USB terminal when the main device is off.
2. Enter the TEST MODE and select [USB BAK c HOLD d] with g keys.
[See TEST MODE] for how to enter the TEST MODE.)
3. Select [USB BAK c LOAD? d ] with h keys and press [ENTER].
4. Saving in the main device starts and it automatically goes off after the normal completion ([COMPLETE] is displayed.).
5. Remove the USB and loading is finished.
* If the following errors occur after "LOAD" is executed, error message will be displayed and "LOAD" will be stopped and the power will be turned off.
• No setting file
• Mismatching between the setting file and the specification of the A/V RECEIVER type to be loaded back
• Error due to Checksum, Signature Check, and Size Check
• Ejecting of USB device (during reading of the setting file)
Precautions
• Files are stored in Root of USB memory.
• Files are read from Root of USB memory.
To make operations such as moving files, be sure to assign the saved file in Root of the USB memory.
Also please be careful not to assign *.avr in multiple numbers.
• The time and date of updating for saved file is fixed to "2006/03/08 20:01."
• In principle, please implement Load without making of factory default settings.
• Depending on the type of USB memory device, the setting file may not have properly been saved even though [COMPLETE] is displayed after a SAVE process.
Before replacing the DMAIN Assy, perform a LOAD process and check that [COMPLETE] is displayed.

UPDATING OF THE FIRMWARE

Workflow


MAIN com, SUB com (EVENT), DSP Flash ROM and Network module Update by USB Memory and the Confirmation of the Version

UPDATE PANEL Mode (Version update)

Copy the UPDATE FILE to the root directory of the USB Memory.
Note: NEVER copy several UPDATE FILES to the root directory of the USB Memory.
Copy only the corresponding UPDATE FILE.
Enter the UPDATE PANEL mode.
Check a current version.
2. Turn off the power to this unit by setting Multi-Zone to "OFF".
3. Connect the USB Memory to the USB terminal (A type) of the front panel.
1. While holding down
"TUNE" key on the front panel, press "STANDBY ON/OFF" key and moves to the UPDATE PANEL mode.
2. The updating process is as follows.


Update time is fluctuated by contents of the update. It will take about 26 minutes at the maximum.
(Actual time is from 3 minutes to 26 minutes.)
Time required for updating varies, because only the programs that require updating will be updated.

Confirmation
Enter UPDATE PANEL mode and check that the programs have been updated.

Idle current adjustment

When any component parts which are within the red square on the following circuit diagram are replaced, the idle current adjustment of that channel is required. (Idle current adjustment for another channel is not required.)
However, when any capacitors are replaced, the adjustment is not required.
(The following circuit diagram is for SL channel, but another channel also has same circuit diagram and same adjustment is required)
