Re: No Sound

Power the unit down totally from the wall socket to allow it to reset. It may have had a processor scramble in the outage and not selecting audio inputs correctly.

My stereo just quit on me there was bad weather but it was on one of those power surge cords it is a pioneer stereo fm-am digital synthesizer tuner

If it was plugged into a surge protector, check the surge protector warranty. There are A LOT of surge protectors that will cover damage to items plugged into them through their warranty system. I've had full home computers and TV's replaced by surge protector companies to avoid having a hit to homeowners insurance.

I have only been giving advice on FIXYA for a very short while but have noticed that an awful lot of the people who relate their product issues , particularly complain about faults developing after power cuts / outages. It is apparent, from a description of the complaints, that damage is being caused by outages that may be a result of power surges blowing electricity sub stations.
There are a lot of damaged audio devices / tvs being affected. As such I advise you TO BUY SURGE PROTECTORS for all you valuable devices.
I have them around the house and although we only get an occasional power cut here in the UK I know that at times they have saved my equipment fron power spikes. The small cost is justified in the long run.

I have a Yamaha htr-3065 HDMI receiver that won't turn on after we experienced a power outage. When I plug the unit in I get a buzz sound from transformer but still won't come on. The fuse and power supply...

If you have any electronics experience you should check the diodes or the bridge rectifier in the power circuit. Look for burned components or bulged capacitors.!!!Always unplug the unit and wait a few minutes before attempting any procedure!! I have found that capacitors usually fail due to voltage spikes which can happen when power is reinstated after an outage. Always use surge protectors on electronic devices. They have a component called an MOV that will absorb voltage spikes and save your equipment.

JVC SP55M HDMI sound quit after power outage

Unplug unit, wait 10 mins then plug back in. If still does not work, check for breaker trip. Be sure outlet still has power.

Yamaha RX V671 will not turn on anymore after a power outage

The protection mode has activated.
Reset the protection mode as follows and see what happens.

Connect power cord to mains and wait 5 seconds or so. While holding down "info" and "tone control" buttons, press "main zone" power button briefly and release, but keep "info" and "tone control" buttons pressed for at least 3 more seconds. The unit should power up. Assuming the reason for the protection has passed or been fixed, the unit can now be turned off and then back on with the "main zone" power button to restore normal operation mode.
If the protector activates again, the fault is still present and the unit needs to be repaired, ideally by a Yamaha authorised repairer.
There are dangerous voltages present in high power amps and a lot of grunt in terms of stored energy - best left to trained technicians.

My receiver won't turn on. All I get is a fast

I am sure you have tried and disconnecting all the speakers and taking the unit to another outlet right? If it works you fried your surge and need to replace it. Otherwise the unit went into that strange power protection mode

No home theater sound

Protect mode will kick in whenever a fault is detected.

You get the unit not powering up, and sometimes you hear a clicking noise, that is the protection switch that keeps shutting down the unit.

Causes that can start protect mode are:

Electrostatic harges on internal circuits.
Leave the unit unplugged for power for one hour or so, this will allow discharge.

Bad speaker wiring.
Check speaker wiring, try unplugging and plugging back, or start after removing one speaker at the time.

Internal fault.
Internal fault is the natural cause for protect mode. If all the above did not work, then the problem is a blown component or an internal fault. In this case the unit must be taken apart , tested and repaired by an experienced person.
If the unit is less than one year old, or if you want to get service, call Sony at the phone number listed on the product documentation.

After receiving information and suggested actions from FixYa it was able to determine that most likely, a power outage and surge had caused the speakers need recalibrating. It was a simple task which utilized the remote, now it works fine.

Protector flashing

Protet mode is a special diagnostic mode that starts when a fault is detected.

When in protection mode the unit is prevented from starting by protection circuit, so to prevent further damage.

Check the speakers and speakers wiring, a contact in speaker wires, or faulty speakers can send the unit in protection.

Try unplugging power cable for one hour or so. then connect cable back and see if you get rid of protect state. Sometimes accumulation of electrostatic charges inside circuit capacitors can kick in protect mode. In that case unplugging the unit from main for some times can get rid of electrostatic charges, and reset circuits by draining power completely.
If that was the problem, you will not get Protect when plugging back power cable.

If you do all the above and still get Protect, then there is a real fault.

In that case the unit may be disassembled and tested to find the fault.

If that is the case I suggest contacting the manufacturer at the number listed on the owners manual, or asking a quote on repair to a local technician.
