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.

Updating Your Network Software
from time to time, updates to your network software may become available. to check for and download these updates:
1. After the Avr has connected to your network, press the remote’s Internet radio source button.
2. on the Avr front panel, simultaneously press and hold the Surround modes and back/ exit buttons.

3. watch the front-panel message display for a message that the unit is checking for software updates. when the message appears, release the buttons.
4. If the message indicates that an update is available, press the front-panel ok button to begin the update.
5. during the update a progress bar and status messages will appear on the message display. do not touch any controls on the Avr and do not interrupt the network connection during the update.
6. when the update is completed the Avr will automatically power off, and after five seconds will automatically power back on. once the Avr turns back on it’s ready to use.
Resetting the Remote
to reset the remote to its factory default condition, simultaneously press and hold the tv Source Selector button and the “0” number button. when the tv Source button relights, enter the code “333.” when the tv button goes out, and all of the Source Selector buttons flash, the remote control will be reset.
Processor Reset
If the Avr behaves erratically after a power surge, first turn off the rear-panel main power switch and unplug the Ac power cord for at least 3 minutes. plug the cord back in and turn the receiver on. If this procedure doesn’t help, reset the Avr’s processor as described below.
NOTE: A processor reset erases all user configurations, including video resolution, speaker and level settings, and tuner presets. After a reset, reenter all of these settings from your notes in the Appendix worksheets.
To reset the AVR’s processor:
1. press the front-panel Standby/on switch to place the unit in the Standby mode (the power Indicator will turn amber).
2. press and hold the front-panel ok button for at least 5 seconds until the reset message appears on the front-panel message display.
NOTE: After performing a processor reset, wait at least 1 minute before pressing any Source Selector buttons.
Connect Your HDMI Devices
If any of your source devices have hdmI connectors, using them will provide the best possible video and audio performance quality. Since the hdmI cable carries both digital video and digital audio signals, you do not have to make any additional audio connections for devices you connect via an hdmI cable.

Programming Macro 
In addition to their normal functions, you can also use the 0 – 9 number buttons and Avr power on button to store macro (Activity) commands – up to 11 of them. each macro can send out up to 19 commands at one time from a single button push. Any Avr remote control button’s function from any mode (except the back/exit button, the light button, and the Activity button) can be programmed into a macro.
NOTE: use caution when programming complicated macros. It isn’t possible to program a pause or delay before sending additional commands after a “power on” command, and the component may not be ready to respond to commands immediately after powering on. to program a macro:
1. to enter the programming mode, simultaneously press and hold the Activity button and the number button or Avr power on button to which you want to assign the macro.
2. press in up to 19 commands that you want stored in that macro button. during each successive button selection, the Source Selector button led will blink once. press the Source Selector button for each device (or Setup button for the Avr itself) before you enter individual commands. this step counts as one of the 19 commands allowed for each macro.
# you can select functions from another mode by first pressing the corresponding Source Selector button and then the buttons where those functions are located within that mode. pressing a Source Selector button also counts as one command.
# for power on, press the Avr or device power on button.
# for power off, press the Avr or device power off button.
3. press the Activity button to end the programming process. the last Source Selector button (or the Setup button) will flash three times.
It isn’t possible to “edit” a command within a macro. to erase the macro:
1. press and hold the Activity button and the button into which you programmed the macro until the Source Selector or Setup button lights up.
2. press the Activity button to erase the macro.
To execute a macro:
press the Activity button, then press the button into which you programmed the macro.
IMPORTANT: keep the remote aimed at the components until all of the macro
commands have been executed. the remote can take up to 10 seconds to send out 19 macro commands.
Recording
Two-channel analog and digital audio signals, as well as composite video signals, are normally available at the appropriate recording outputs. to make a recording, connect your audio or video recorder to the appropriate Avr output connectors as described in
the making connections section, insert blank media in the recorder and make sure the recorder is turned on and recording while the source is playing. refer to the recording device’s instructions for complete information about making recordings.
NOTES:
1. the Avr does not convert analog signals to digital or vice versa.
2. hdmI and component video sources are not available for recording.
3. please make certain that you are aware of any copyright restrictions on any material you record. unauthorized duplication of copyrighted materials is prohibited by law.
