Question about Audio & Video Receivers

1 Answer

I have a Philips WAC700/5 which, when switched on, will not progress past the booting up stage. I have tried a couple of fixes already (checking the robbon connectors and a firmware recovery) but no joy. Just prion to this problem the unit stopped in the middlt of a track after about 1`0 minutes play and on both occaisions could only be resolved by switching off and re booting. On the third re-start it would not go past the booting up stage. Any ideas?

I know you tried firmware recovery already. But if it breaks in middle of boot up, then is the firmware.

    You re-load the firmware backup and restore the system in the following way:
    Hold pressed SOURCE and STOP buttons while plugging into the mains supply.

    This will recall recovery option, follow instructions.



    If you this the above several times and it did not work, this means that the recovery backup firmware had been damaged. In this case you will need to contact a service centre to have your backup recovery restored.

I have Sansui G-9000, and its phono stages emit a buzzing/distorted sound even if a turntable is not connected. There is also no sound coming from the left speaker (I already tried switching the speakers,...


The Phono section has a very high level of amplification and so the audio input is very sensitive. So a possible faulty/loose grounding of the input can create a HUM which can be due to even a poor shielding of the input from stray AC factors. So you need to check for the these factors that can bring in the hum , you can confirm by isolating the phono circuit and working to the faulty stage.
Also it can be due to a faulty power supply - non filtering in DC- to the phono preamplifier.Finally faulty capacitors in power and feedback circuits can be a reason- check the negative feedback circuit which can be an op-amp with a feedback , check the capcitors here as a higher amplification can also be a reason.- check the preamp IC.

How do I reset my I pod it says disabled and a whole bunch of numbers? HELP PLEASE


for resetting the ipod follow these steps

  1. Verify that you have an active Internet connection, because you may need to download new versions of the iTunes and iPod Software.
  2. Download and install the latest version of iTunes if necessary.
  3. Open iTunes. Connect your iPod to your computer using the USB or FireWire cable that came with your iPod.
  4. After a few moments, your iPod will appear in the Source panel in iTunes.
  5. Select your iPod in the Source panel. You will see information about your iPod appear in the Summary tab of the main iTunes window.
  6. Click Restore.
  7. If you are using a Mac, you will be asked to enter an administrator's name and password.
  8. A progress bar will appear on the computer screen, indicating that stage one of the restore process has begun. When this stage is done, iTunes will present one of two messages with instructions specific to the iPod model you are restoring.
  9. Disconnect iPod and connect it to iPod Power Adapter (typically applies to older iPod models).
  10. Leave iPod connected to computer to complete restore (typically applies newer iPod models).
  11. During stage two of the restore process, the iPod displays an Apple logo as well as a progress bar at the bottom of the display. It is critical that the iPod remain connected to the computer or iPod power adapter during this stage.
  12. Note: The progress bar may be difficult to see, because the backlight on the iPod display may be off.
  13. After stage two of the restore process is complete, the iTunes Setup Assistant window will appear. It will ask you to name your iPod and choose your syncing preferences, as it did when you connected your iPod for the first time.
good luck and do rate the solution if helped

I have a hk25 II receiver. It is about 20 years old. It has been working fine but I had to relocate it and now the speakers sound is distant and the balance control does not work. I only have two speaker...


Hi Steve

I have worked on these units in the past as a Harman Kardon service agent. They are decent units and well worth persevering with.

By the sound of your symptoms, the signal is not making it from the pre amp stages to the power amp stages. This can be caused by a few different things.

1. check that the tape monitor switches have not been engaged
2. check to see that the pre out main in connections on the rear of the unit have been jumpered. See page 12 of the user manual for info about this.


You can also download a user manual for the amp from Kardon-AVR-25-II-Receivers-manual/id/390bh145/t/2/">here to assist you with working things out. I suspect that the jumpers are missing at this stage

I suspect that the jumpers on the rear are missing at this stage. Check for that and get back to me.

My fr 996 shuts down when the volume is increased can you suggest anything which be causing this?


There are a number of potential causes for this. Among them could be defective coupling capacitors between the pre-amp stage and the final stage. This would allow DC voltage to pas through to the final stage where the protection circuits would detect it and shut the unit down. Without taking internal measurements, it is impossible to determine the problem with this unit. I would suggest that you get a detailed repair estimate, report the results here and we should be able to walk you through the actual repair.

I have a nad 7600 receiver. it is cracking and popping loudly whenever you try to adjust the volume. What could be the problem


There are a couple of possibilities here. The crackling is likely to be a dirty control. Spraying it out with electronics switch cleaner that contains a lubricant should resolve that. The popping usually indicates a build up of DC current between the amp stages. This can happen because of defective coupling caps. That may take a little more detective work. Try cleaning the controls first. If that fails to reolve the entire problem, update this and we'll start looking at circuit components.

It is likely that the PA stage has developed an offset voltage in the output stage. The faulty amplifier channel can be found by progressively disconnecting the collectors of the of the power transistors until the protection fault disappears. Once the faulty channel is found the the cause of the offset has to be traced to the faulty transistor or resistor. Don't forget that if you can smell smoke or burning then there are likely to be components(esp transistors) that have been damaged by the fault.
I had a Luxman unit that destroyed 5 transistors in the output stage that was due to an open .5W resistor in the driver stage.
Good luck.
