SOURCE: No output on main speakers

I have experienced a similar problem with my Sony STR-GX57ES and took it to a certified tech only to find it needed the power supply replaced. I opted to hunt down a compatible power supply but have been unsucessful thus far. That being said I picked up an STR-D665 for next to nothing and found the power supplies to be quite different (you would hope so any, with the ES meaning Elivated Standard and all) but with the D665 working flawlessly I'd rather have something working than nothing. Good luck!

o Front display,wrong functions on front buttons.

CAUSE
Corrupted data is stored in the NVM memory (IC605) or part of the data is erased.
The model option data flags are erased or set incorrectly.

SOLUTION
1. CAPACITOR AND RESISTOR REPLACEMENT NOTE
For continuous reliability, regardless of the symptom, ALWAYS check and replace if necessary C701 in the correct mounting position and ALWAYS modify R668/R669 from 10k to 4.7k.
1.1. Open the set and replace C701 "470µF 10V" (1-126-925-11)
1.2. Make sure to mount C701 in the correct way, the positive (+) side points to the edge of the MCB. NOTE THAT THE WHITE PRINTING FOR C701 ON THE MCB IS INCORRECT (REVERSE)!
1.3. Replace R668 and R669 "10k" (1-216-675-11) with "4.7k" (1-216-667-11).

2. OPTION DATA SETTINGS
2.1. Connect the unit to the AV input of a television with a SCART connection cable in order to enable the on-screen display.
2.2. Enter the unit into test mode: press the record button on the front panel, then press the menu button on the remote commander for 5 seconds until the option setting display appears on the connected television. The option display has 8 columns and 9 rows with decimal numbers.
2.3. Enter the correct option settings according to the model and model destination. Refer to the option setting table in this document or page 5-6E of the Service Manual.
2.4. The option number is selected with the FF, REW, STOP and PAUSE buttons on the remote commander.
2.5. Pressing the OK (PLAY) button on the remote commander activates the selected option number. An activated option number appears in reverse colour.
2.6. After all required option numbers are activated press the MENU button on the remote commander to save the changes. A message "Please wait" appears for a few seconds after which the setting is completed.
2.7. Turn the power OFF and back ON.

3. HEAD SWITCHING PULSE ADJUSTMENT
3.1. Remove the front panel.
3.2. Insert a VHS alignment tape (like KRV-4821PS).
3.3. Press the TEST button located behind the front panel at the left-hand side of the tape/display area.
3.4. Press the SP/LP button on the remote commander. The adjustments are operated automatically.

4. FUNCTIONAL CHECK
4.1. Re-assemble the unit and perform functional checks.
4.2. Check for correct language setting.
4.3. Confirm basic functions like Playback, FF, REW, etc.
4.4. Check for a noise-free picture quality in playback mode.
4.5. Switch the unit on and off for a couple of times.
4.6. Perform a timer record to confirm the function and picture quality.
4.7. Check the SmartLink function (if available with the connected television) by transferring the TV preset settings to the VHS recorder.

Hi...
Is it LOUD when you first turn it on?
Are the speakers firmly connected at BOTH ends?
If that's all OK then one or both of the output modules in the power amp have failed.
Parts are available

Kenmore 665.6061200 over range microwave. Problem started a few days ago with a clicking sound from the RH side of the unit (seemingly behind the control panel), about 3 clicks per second for about 3-4...

The most likely cause of the clicking sound is the power relay that is connected to the microwaves PCB (circuit board) that turns the magnetron on and off. If starting to fail it may result in multiple clicks, then once fully failed, your microwave would simply not heat anything (as the high voltage components would not be getting power).
Unless you have a strength in electronics and repair, and understand the lethal dangers involved in working on a microwave, even one that is unplugged, this problem will likely need to be repaired by a qualified service centre.
Depending on the microwave design and the technician the whole relay circuit board may need to be replaced making this repair vary from relatively inexpensive to more expensive.

No output but all checks seem positive

You should hear 2 clicks..one when you first turn the unit on, and a second one about 5-20 seconds later. I'm going to guess you don't hear the second click, which means that your NAD has DC Offset, meaning a damaged amplifier.

Sound has gone on Samsung LE23R87!

Check whether the audio is muted by accidental press at remote control button. Enter its sound menu, and check it. If muted, as you know there will be no audio output. If not muted, Check the speaker/s. If found OK; check and replace the damaged component/s at its audio output section circuit board. If needy, replace this board as card basis.

Hi..

I suggest you to disable all HP related items, which will not startup at system boot up and might not cause any issues.

Disabling HP Applications from MSCONFIG:
----------------------------------------
1. Click Start and select Run.
2. Type MSCONFIG and press Enter.
3. Click the Startup tab.
4. Clear the checkboxes for all HP related applications.
5. Click OK.
6. Restart the system.
You can restore any of the removed items by repeating the above steps and replacing the checks for the designated applications.

For Windows Vista

Turn off the Terminate and Stay Resident programs MSCONFIG in VISTA
1. Click the Start icon.
2. In the Start Search text box located above the Start icon, type msconfig and then press Enter.
3. On the User Account Control window, click Continue. The System Configuration window displays.
4. Click the General tab.
5. Select the Selective Startup check box.
6. Verify that the Load Startup Items check box is not selected.
7. Click the Services tab.
8. Select the Hide All Microsoft Services check box.
9. Click Disable All.
10. Click OK.
11. Click Restart to apply the changes. The computer automatically restarts.
NOTE: After the computer restarts, a System Configuration message might display. If it displays, Ignore this message.


I hope this helps you...

Thanks..

I don't get any front display or any sound when turned on.

Do you hear any clicks? If not, the standby transformer or related circuitry is bad. If you hear 1 relay click...the audio output section is most likely the problem. The first click you hear is the main power relay...and should see display.. the second relay click is the protection circuit relay engaging to let audio to your speakers...if the second click is not heard (it should occur in 3 to 5 seconds) there are shorted output transistors or a shorted output IC trying to blow your speakers with 50 to 75 volts dc. The protection circuit monitors the speaker lines for voltage. They should always read milli-volts only...not even 1 volt.Anyway, good luck

After playing my AVR-2802 Denon a while approx 3-4 hrs the sound output juts turns off, after letting it cool down a while it will resume playing ok , then repeats the cycle of loss of audio output.

Seems to be a heat related issue, when it " cools down " awhile it resumes audio output? Be sure you are allowing air circulation around the receiver, I am note sure but I do not think Denons have inboard fans, you could try a ciculating air fan on the unit after playing it for a couple of hours if the receiver feels hot.

I have a pioneer 5.1 channel surround sound system and it powers up and everything seems to go fine but you go to turn it up and no sound comes out of the speakers already checked speaker wire connections...

Does the protection relay click 3 to 5 seconds after initial power on??? If not, your unit is staying in "protect" mode to save your speakers because the output transistors or output IC is shorted and sending 40 to 60 volts at your speakers. Not a good thing, but at least it saves your speakers.
Good Luck!
