If your Sony S-Master CMT-SPZ50 audio system keeps going into standby mode shortly after turning it on, there are a few troubleshooting steps you can try to resolve the issue:

1. Power cycle the system: Turn off the audio system and unplug it from the power source. Wait for a few minutes, then plug it back in and turn it on. This can help reset any temporary glitches or issues.
2. Check the speaker connections: Ensure that all the speaker wires are properly connected to the audio system and the speakers themselves. Make sure there are no loose or frayed wires that could be causing a short circuit or interruption.
3. Disconnect external devices: If you have any external devices connected to the audio system, such as smartphones or MP3 players, try disconnecting them to see if the issue persists. Sometimes, an incompatible or malfunctioning external device can cause the system to go into standby mode.
4. Reset the system: Look for a reset button or option on the audio system. It could involve pressing a specific combination of buttons or using a small reset pinhole. Refer to the user manual for instructions on how to perform a system reset.
5. Check for overheating: If the audio system is located in a confined space or if the vents are blocked, it could lead to overheating and cause the system to go into standby mode. Ensure that the system has adequate ventilation and is not exposed to excessive heat.

If your Sony CDP-CX355 CD player keeps moving the carousel back and forth without completing a full rotation, it could indicate a mechanical issue. Here are a few troubleshooting steps you can try:

1. Power cycle: Turn off the CD player, unplug it from the power source, and wait for a few minutes. Then, plug it back in and turn it on. Sometimes, a power cycle can resolve temporary glitches.

There are a few possible reasons why your Sony 60 disc stereo model MHC-GS100 won't rotate CDs and just continuously makes a grinding or motor turning noise but the tray doesn't move. Here are some of the most common causes:

• The CD drive belt is worn out or damaged. The CD drive belt is responsible for moving the CD tray and the CD itself. If the belt is worn out or damaged, it may not be able to move the tray or the CD.
• The CD drive motor is faulty. The CD drive motor is responsible for rotating the CD. If the motor is faulty, it may not be able to rotate the CD.
• The CD drive gears are worn out or damaged. The CD drive gears are responsible for moving the CD tray and the CD itself. If the gears are worn out or damaged, they may not be able to move the tray or the CD.
• The CD drive control board is faulty. The CD drive control board is responsible for sending signals to the CD drive motor and gears. If the control board is faulty, it may not be able to send the correct signals to the motor and gears.

If you have checked all of these possible causes and you are still having problems with the CD drive, you should contact Sony customer support for help. Here are some tips to help prevent this problem from happening in the future:

• Do not overload the CD drive. Overloading the CD drive can put unnecessary strain on the drive and can lead to premature wear and tear.
• Do not use damaged CDs. Using damaged CDs can damage the CD drive.
• Clean the CD drive regularly. Cleaning the CD drive can help to remove dust and dirt that can build up and cause problems.

I hope this helps!

The only way to pinpoint the problem here is with voltage measurements or waveform similarities. At least you have one good channel for reference. Could just be a faulty joint or connector or a blown output.

Does it blink to the beat of the sound or is it flashing? If it's flashing with no audio it usually means overheating. If it beats to the music it's usually is a warning that you are "clipping" which means you're overdriving the amplifier This can damage the speakers and overheat the amplifier. Avoid red lights by having each stage of amplification not exceed 95%.

Replacing the mechanism includes the motor assembly. The motor will not spin up until the laser acheives focus. I would replace the laser with a new one, not second hand as you may never get to know, where the fault lies.

It seems like you're experiencing an issue with the sound speakers on your Sony DAV-TZ715 system when using the USB function with RFD multi mode. However, the problem resolves itself when you switch to other functions like TV. There could be a few potential causes for this issue: 1. Interference: The USB function may be more susceptible to interference, which is causing the noisy sound on the SUR L and R speakers. This interference could be originating from the USB source itself or other nearby electronic devices. 2. Compatibility: There could be a compatibility issue between the USB source and the RFD multi mode on your Sony system. It's possible that the USB source's audio format or settings are not fully supported by the RFD multi mode, resulting in the noise issue. 3. Firmware or software issue: There might be a firmware or software problem with your Sony DAV-TZ715 system. It's worth checking if there are any firmware updates available for your system that could potentially resolve the issue. You can visit the Sony support website or contact their customer support for assistance with this. To troubleshoot the problem, you can try the following steps: 1. Test with a different USB source: Connect a different USB device or try playing different audio files from the same USB source to see if the issue persists. This will help determine if the problem is specific to the USB source or if it's a more general issue. 2. Check audio settings: Explore the audio settings on both the USB source and the Sony system. Make sure the audio format and settings are compatible with the RFD multi mode. You can refer to the user manual of your Sony DAV-TZ715 system for instructions on adjusting the audio settings. 3. Isolate interference: Move the USB source away from other electronic devices and potential sources of interference, such as Wi-Fi routers, cordless phones, or microwave ovens. This might help reduce any external interference that could be affecting the sound quality. 4. Perform a factory reset: If none of the above steps resolve the issue, you can try performing a factory reset on your Sony system. This will reset all settings to their default values. Refer to the user manual for instructions on how to perform a factory reset. If the problem still persists after attempting these troubleshooting steps, it's recommended to reach out to Sony customer support for further assistance. They will have access to specific knowledge about your Sony DAV-TZ715 model and can provide more specialized guidance in resolving the issue.

I am guessing that the unit is broken and the display screen does not work either.

Sony DAV-IS10 not working.


Pearce Hamblin
My Sony Dav is10 is just dead. It doesn't show and sign of life and when I try to power it on it just doesn't do anything. Any answers please ?

There are a few things you can try to troubleshoot your Sony DAV-IS10 and get it working again:

Check the power source: Ensure that the power outlet you're using is working properly. You can try plugging in another device to confirm this.

Check the power cable: Make sure that the power cable is securely plugged into the unit and the power outlet. If the cable is damaged, try replacing it with a new one.

Check the fuse: Some electronic devices have an internal fuse that can blow, which can cause them to stop working. Check the manual to see if your Sony DAV-IS10 has a fuse, and if so, replace it with a new one if it's blown.

Reset the unit: Some electronic devices can be reset by unplugging them from the power source and leaving them unplugged for a few minutes. Try this and then plug it back in to see if it works.

If none of these steps work, it may be a hardware issue that requires repair or replacement. You can contact Sony customer support for assistance in this case.
