Question about Sony STR-DE310

1 Answer

Receiver won't turn on

The receiver started tripping while on but would turn back on and be fine, even at low volume. Which leads me to a power issue, now the receiver won't turn on at all even on a different curcuit. I checked all speaker cables and they seem ok.

    The fuse is a cylinder fuse and looks white instead of clear. How can I tell if it is bad?

Disconnect all the speaker wires, then turn the unit on. If it does not power on and the standby light is "out" pop the top and check the internal fuse by the power cord. Beyond that, without the proper testing equipment, it's all a guess. If the unit turns back on with all the wires disconnected, then reconnect your speaker wires one by one and test each time. If it does not cut out, you found the problem. Wire touching. If it cuts out, disconnect wire at the speaker and re test, if it still cuts out, replace the wire and try again. Then re connect the same speaker to the new wire and test. If your lucky, all will be well. If not, it will need to be serviced or replaced, based on cost. Hope this helps

1990 Volkswagon Jetta won't turn back on after long drive.


Then you have a start up problem and it reside with the cold start valve,The cold start valve operates even if the vehicle is warmed up,the cold start valve can be plugged up,or even have a bad connection,The cold start valve operates by a thermotime switch.This switch located on the near bottom of the radiator may have gone bad or disconnected,Here is the easy cost effective route, replace them both,it will cost more to trouble shoot it than just replace it.

I own a RX-V1065 AV receiver. Whenever I turn the volume above a certain low volume level the receiver powers off. I can than turn it back on and continue watching my theater at a low volume. Anything...


If this just started happening I'd look for loose speaker wires or...

Generally speaking, an amp protects itself from heat, shorts and overloads by refusing to turn on or stay on.


Overloads can be from excessive periods of high output and shorts would be wiring issues or a speaker blowing up.


You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.


If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.


If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced hands-on tech.

I bought a Denon AVR 791 receiver two months ago, work great, sound great with my Definitive Technology Speakers but 3 days ago while I was watching a movie on my PS3 the receiver turned off on the higher...


Clearly, it thinks you're overdriving it.

Blinking Power Indicator every 2 seconds means the internal temperature is high. (Page 76 of the manual)

Every half-second - speaker impedance too low.

Consider the load presented by the speakers and what their minimum impedance might be.

Check for loose speaker wires.

I JUST REPLACED MY OLD RECEIVER WITH A YAMAHA AND DON'T SEE WHERE TO CONNECT THE POWER FOR THE CD AND TAPE PLAYER. DO I PLUG THEM INTO A POWER STRIP?


Yes, that will be fine just make sure its the same AC power as the new Yamaha is using.

Before connecting any AC mains always turn off your Amp, and don't turn back on again until all the signal cables for the new equipment are connected.

When checking if it all works, always start with low volume to check everything is correct.

Hope this helps

Try to disconnect speakers one by one and see if any of them causes the problem.

My unit keeps shorting out. wondering if its my car or the unit?


I would hazard to guess that you are running a speaker "ohm load" that is less than 4 ohms per channel. Or 8 ohms if you are running in bridged mode. You should NEVER blow a fuse. Re-check all your connections. Your "cutting out when the headlights are on" problem is due to low battery voltage to the amp. Use bigger wire on both your +12 lead and your ground lead. Make sure your battery to chassis ground lead is even bigger than your amps power lead. Make sure your amps ground lead is big, beefy, and short. And get a boost capacitor. When you have a huge amp in the trunk, you must treat it as if you are trying to run your engine starter from the trunk when it comes to the size of your hot wire and ground wire. Good luck.

Power problem?


???

1. Is the head unit powering the speakers directly or through an amp?
2. What ohm load (4,8,) per channel and how many speakers?
3. Does it do it with the bass set all the way down?

If you have access to a voltmeter see what the voltage is on the yellow and black wires when it is diming. It should be stable ~ 13.5v with car on. if its < 10v when dimming either there is:

1. Shorted speaker lead.
2. Bad ground to radio.
3. loose power feed to radio.
4. Ohm load below 4 ohms, causing the eccess current draw.

Your speakers are way tp powerful you should only use speakers just over what the amp is rated at the most and check your impedance is not lower then 6 ohms and turn the bass to half way i am using 60 watt bookcase psb speakers and they work just fine and they pound no problem
