    The problem of the center channel cutting out during play has recently ( a couple weeks) struck me too, only I don't hit the side of the receiver to get it back, but simply turn the unit off and then back on again, which works about 90% of the time.


    I got the STR-DE445 unit as a part of a HTIB package Sony was selling in 2000. It was an entry level unit, but I didn't have a whole lot of money and still wanted a 5.1 DTS solution. I've had this receiver since then and it's been a champion to say the least. I've moved three times, have upgraded speakers, and have had a son who is all too good at finding daddy's electrical gear, and this is the first time the unit has had as much as a cough. In all fairness to Sony, it's been one heck of a performer.


    When the audio clipping first started I was bugged, but then when I thought about it I've certainly gotten plenty of use from this unit, and nothing really lasts forever. Besides, with the technology that is available today in most of the entry level to mid-range units that cost just as much as this did when I bought it new almost ten years ago, it doesn't make sense why one wouldn't simply put this unit to sleep and upgrade. Rather than spending any sort of money to fix a discontinued piece of equipment, spend $600 bucks and snag the Sony STR-DG920. That's my plan if I can find one. They debuted on the Sony website today and are already out of stock.

Slapping the unit causing the missing sound to come back tells me that there is something loose in the receiver. This could be a bad solder joint or dirty switch contact. Vibrations, such as sound, could be jarring the bad connection and causing the sound to cut out when it was just working a few seconds before. I don't believe you have a bad part in the receiver. When a solid state device fails, its gone for good. Again, it soulds like a bad connection. Finding a bad solder joint can sometimes be difficult. What you need to do is take the cover off so you can see the bottom of the PC board and using a good light source and magnifying glass, look for the bad connection. You can try running the receiver with the cover off and using a plastic pen, try pushing down on the PC board and see if you can make the sound cut out. You may be able to isolate the area by where you push on the board. Look for loose wires too. While you have the receiver open, buy some electrical contact cleaner in a spray. Radio Shack used to sell this as TV Tuner cleaner. I don't think they carry it anymore though. Spray the switches and rotate them back and forth several times. See if this resolves the problem. If you do find a bad solder joint, all you have to do is resolder it with some new solder. Make sure you do this with the power OFF. You're not looking at a big bill here. It's an easy fix once you find it.

Good Luck.

The front center speaker bangs then it hisses constantly never stops but the radio plays fine


The noise may be from distortion cause by interference. It may be from the wire. Trace the wiring of the speaker to see if there are loose connections at its back or exposed conductors. Check if there are magnets or power cables crossing on the path of the wires.

RX-V665 Yamaha reciever has been working great. Use it for surround sound and outside, zone two speakers. Recently started turning off during movies. I run blu-ray through receiver. When playing Star Wars...


You may find a solution by doing some of the things I have tried - see below

I recently puchased this model to replace an older Yamaha system that also had this shut-off problem. The new RX665 system has the same problem but I check the impedance setting using the instruction in the manaul anyway. The problem persists. I have check all speaker wire to make sure nothing was touching. I did find one wire touching on the center speaker but the problem persist.

Since the problem followed me when I moved and with a new amp, I am beginning to think I am have a speaker that's causing this - maybe the sub.

Car amplified speakers...massive bang...


This kind of problem is often caused by transients in the signal
processor as it powers down finding their way into the signal path,
which the amplifier then transmits to the speakers.

Usually this can be solved by adding a little turn-off delay to the
processor. This allows the processor to stay powered on for a short
time after the amplifiers have powered down, thus preventing the pop.

Many components sold today (such as crossovers, equalizers, etc) have
delays built-in. Read your manual to see if it is possible to set this
delay on your piece of equipment or be sure to look for this feature
during your next car audio purchase.

If your processor does not have this feature, you can build your own
delay circuit with a diode and a capacitor. Add a 1N4004 diode in
series with the processor's turn-on lead, striped side towards the EQ.
Then add a capacitor in parallel, the (+) side of the cap connects to
the striped (processor) side of the diode, the (-) side of the cap goes
to ground (not the radio or EQ chassis - connect to the car chassis).

Experimenting with the cap value will give you the right amount of delay
before the EQ shuts off. You don't want it too long, just long enough to
make sure the amp is off before the EQ powers down. 220 - 1000 uF is
about right, and make sure the cap is a polarized electrolytic, 16V or
higher. Also keep in mind that the diode will introduce a 0.7V drop on
the remote wire, which can cause the processor to power down before the
rest of the system.

7.1 speaker setup: no sound coming from right front/surr speakers


Solution to having no sound coming from certain speakers in a 7.1 speaker setup for TX-SR606 receiver when playing a DVD.

Review the cable setup for the DVD player since it was identified as the source of the problem. Best to unplug and plug in the cables to ensure they contact the back of the receiver's RCA jacks. Redo the microphone setup for Audyssey 2EQ calibration. A good chance that it is the cable that may have caused the malfunction and loss of sound from the speakers. The cables can come loose during setup and not plugged all the way to the back of the RCA jacks or a defective cable causing signal loss.

My system shot down during a movie


The reason why your receiver is going in protect is because there is a short circuit happening. This would either be on your speaker wires, speakers or receiver itself. What you want to do to check would be:
1. Unhook all sources and speakers from your receiver.
2. Turn on your receiver and crank up the volume to maximum, if your receiver does not shutdown or go on protect then the receiver is OK. If it does shutdown and go on protect then its an internal problem on the receiver and you would need to send that over to an authorized service center.
3. Hook up a source and 1 speaker. Play something from the source or the fm tuner, Crank Up the volume to about 46 or 47 volume. If the receiver does not shutdown, its good.
4. Hook up a second speaker and repeat the process until you encounter the pop and shut down
if for example you encounter the pop on the 4th speaker, try changing the speaker wires.
5. If the receiver still shuts down then it would be a short on the speaker itself and it would need to go to an authorized service center.
