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.

YAMAHA RX-V367 - HTR-3063 AV RECEIVER SOFTWARE UPDATE AND SELF DIAGNOSTICS

YAMAHA RX-V367 - HTR-3063 AV Receiver Software update and self diagnostics

YAMAHA RX-V367 - HTR-3063 

UPDATING FIRMWARE
 Confirmation of firmware version and checksum
Before and after updating the firmware, check the firmware version and checksum by using the self-diagnostic function menu. Start up the self-diagnostic function and select “25. ROM VER/SUM/PORT” menu.
Using the sub-menu, have the firmware version and checksum displayed, and note them down.
(See “SELF-DIAGNOSTIC FUNCTION”)
* When the firmware version is different from written one after updating, perform the updating procedure again from the beginning.
Initializing the back-up IC (EEPROM: IC222 of the DIGITAL P.C.B.)
After updating the firmware, the back-up IC MUST be initialized by the following procedure to have propermemorization of the set up information (soundfield parameters, system memory and tuner presetting, etc.).
Start up the self-diagnostic function and select “24. FACTORY PRESET” menu. (See “SELF-DIAGNOSTIC FUNCTION”) Select “24. PRESET RSRV”, press the  (Power) key of this unit to turn off the power once and turn on the power again. Then the back-up IC is initialized.
Required Tools
• DVD or CD player (with DIGITAL OUTPUT (OPTICAL or COAXIAL) jack)
• Optical cable (when OPTICAL jack is used)
• Digital audio pin cable (when COAXIAL jack is used)
• Firmware CD
* Download the latest firmware from the specified download source and create the firmware CD.
Operation Procedures
1. While pressing the “INFO” key of this unit, connect the power cable of this unit to the AC outlet.
The FIRMWARE UPDATE mode is activated and “CDDA Upgrader” is displayed
2. Play the firmware CD on the DVD/CD player. Writing of the firmware starts automatically.
3. When writing of the firmware is completed, “Update Success”, “Please...” and “Power off!!” are displayed repeatedly.
* When the version of the firmware to be written is the same as the one existing in this unit, “Same Version”,
“Please...” and “Power off!!” are displayed repeatedly. (Updating is not necessary.)
If the display remains unchanged for more than 10 seconds after starting the firmware CD play procedure, perform the firmware CD play procedure again from the beginning.
If “FILE CORRUPTED” is displayed after “Address:XXXXXX”, make sure that the written data is not corrupted and perform Steps 1 to 7 of “Operation Procedures” again.
If “Upgrade Failed” is displayed, perform “operation procedures” again from the beginning.
4. Press the “ ” (Power) key of this unit to turn off the power.
5. Eject the firmware CD from the DVD/CD player.
6. Start up the self-diagnostic function and check that the firmware version and checksum are the same as written ones. (See “Confirmation of firmware version and checksum”)

Self-Diagnostic
Starting Self-Diagnostic Function
While pressing the “TONE CONTROL” and “STRAIGHT” keys of this unit as shown in the figure below, press the “ ” (Power) key of this unit to turn on the power.
The self-diagnostic function mode is activated.
Starting Self-Diagnostic Function in the protection cancel mode
If the protection function works and causes hindrance to trouble shoot, cancel the protection function as described below,
and it will be possible to enter the self-diagnostic function mode.
(The protection functions other than the excess current detect function will be disabled.)
While pressing the “TONE CONTROL” and “STRAIGHT” keys as shown in the figure above, press the “ ” (Power) key to turn on the power and keep pressing those 2 keys and the “ ” (Power) key for 3 seconds or longer.
The self-diagnostic function mode is activated with the protection functions disabled.
In this mode, the “SLEEP” segment of the FL display of this unit flashes to indicate that the mode is self-diagnostic function mode with the protection functions disabled.
CAUTION
Using this product with the protection function disabled may cause further damage to this unit. Use special care for this point when using this mode.
Canceling Self-Diagnostic Function
1. Before canceling self-diagnostic function, execute setting for FACTORY PRESET of main menu No.24. (Memory initialization inhibited or Memory initialized).
* In order to keep the user memory preserved, be sure to select PRESET INHIBITED (Memory initialization inhibited).
2. Press the  (Power) key of this unit to turn off the power.
Display provided when Self-Diagnostic Function started
The display is as described below depending on the situation when the last time the power to this unit is turned off.
1. When the power is turned off normally:
The FL display of this unit displays “NO PROTECT” then the main menu (sub-menu “1. ANALOG BYPAS” of main menu 1 BYPASS) a few seconds later
2. When the protection function worked to turn off the power:
The FL display of this unit displays the data of protection function which worked at that time then the main menu (sub-menu “1. ANALOG BYPAS” of main menu 1 BYPASS) a few seconds later.
Note: When you reactivate the self-diagnostic function after turning off the power once by pressing the “ ” (Power) key, “NO PROTECT” will be displayed because that situation is equal to “1. When the power is turned off by usual operation:” described above.
However the protection function history is stored in a back-up IC with a backup.
When the protection function worked due to excess current.
Cause: An excessive current flowed through the power amplifier.
Supplementary information: As current of the power amplifier is detected, the abnormal channel can be identified by checking the current detect transistor.
Turning on the power without correcting the abnormality will cause the protection function to work immediately and the power supply will instantly be shut off.
When the protection function worked due to a short between speaker terminals.
Cause: The line between speaker terminals is shorted.
Supplementary information: As the excess current is detected after operation of the speaker relay, the shorted speaker terminal and the connected speaker can be identified.
Turning on the power without correcting the abnormality will cause the protection function to work immediately and the power supply will instantly be shut off.
When the protection function worked due to abnormal DC output.
Cause: DC output of the power amplifier is abnormal.
Supplementary information: The protection function worked due to a DC voltage appearing at the speaker terminal. A cause could be a defect in the amplifier.
Turning on the power without correcting the abnormality will cause the protection function to work in 3 seconds and the power supply will be shut off.
When the protection function worked due to abnormal voltage in the power supply section.
Cause: The voltage in the power supply section is abnormal.
Supplementary information: The protection function worked due to a defect or overload in the power supply.
Turning on the power without correcting the abnormality will cause the protection function to work in 1 seconds and the power supply will be shut off.
When the protection function worked due to excessive heatsink temperature.
Cause: The temperature of the heatsink is excessive.
Supplementary information: The protection function worked due to the temperature limit being exceeded. Causes could be poor ventilation or a defect related to the thermal sensor.
Turning on the power without correcting the abnormality will cause the protection function to work in 1 seconds and the power supply will be shut off.
* For detection of each protection function, refer to main menu described later.
History of protection function
When the protection function has worked, its history is stored in memory with a backup.
Even if no abnormality is noted while servicing the unit, an abnormality which has occurred previously can be defined as long as the backup data has been stored.
The history of the protection function will be initialized when self-diagnostic function is cancelled.
