Question about Polk Audio SWA500 Amplifier

1 Answer

Polk amp blinks green and red and sound burps and is distorted

When i run my home theater for 60 minutues or so my swa amp starts to blink between red and green on its power/stand-by indicator light. the base sounds start to make scratchy burping sounds and i have to go shut the amp down.

it happens even if i disconnect the l/R inputs - i think the unit is hosed up. i thought it might be heat but the network closet is super well ventilated and the unit is not hot/under stress.

Could be a power related problem or you may have speakers connected that have an impedance less than recommended

Denon avr 3805 is blinking red and blinking green and won't stay on

Do a reset to the set. Just unplug it from AC mains wall socket and replug it after 3 minutes or so; or just go to ints user manual to know, how to reset it to factory defaults, and do it. OK.

I have a GK Backline 600 bass amp with an intermittent pre amp problem. Sometimes it works fine then starts distorting. One odd thing i've noticed when I shut it down, about 7 seconds later the clip light...

This is not a problem with dirty components. There is a semiconductor inside that is sensitive to heat and is failing. This unit should be taken to a service shop before complete failure. It has the potential for frying the output section depending upon the part that fails.

Please seek professional assistance with this repair.

My amps stays in the clip mode where as the light on the two channel stays red

Page 7...

CLIP: red, to the left of each Gain control.

Normal indication: illuminates whenever the amplifier is driven beyond full power. The LED's brightness indicates the amount of distortion. Distortion that causes only brief flashing may not be audible.

During muting, the indicator fully illuminates. This occurs during normal "On-Off" muting.

Abnormal indication:

•Bright red illumination while the amp is being used indicates either thermal muting or a shorted output.

•If the amplifier overheats, the fan will run at full speed, and operation should resume within one minute. Allow the fan to run, and make sure the amplifier ventilation is adequate.

•A shorted or overloaded output circuit will cause excessive Clip flashing and possible overheating.

•If distortion is audible without a Clip indication, the problem is either before or after the amplifier. Check for damaged speakers or overloaded signal source. The amplifier Gain control should be in the upper half of its range to prevent input overload.

I have a crown Itech 4000 and when I plug it in it the green light around the front power button does not light up and when I turn on the power button on the front only the blue "power" light...

Nice amp. There is a breaker/switch on the back that trips to protect the amp. Turn it off, then back on and see if the green indicator comes back. If the breaker trips again, that's probably an indication of a more serious internal problem.

I have an adcom GFA 5400 amp. Whenever I turn it on, the thermal protection light Is on for the left speaker and every 7seconds or so the distortion light for the left speaker lights up and a loud noise...

You'll need to take it to a Pro.
Where in the US are you ? I could suggest a repair shop maybe.
The trouble is either failed power supply capacitors and/ or a couple of power transistors gone bad in the trouble channel.

Power issues with Amp

You have an internal short or your pos/neg or speaker wire connections are shorted somewhere. Double check them and if they are good the amp is bad

Distortion with HK AVR 144

This sounds like the amplifer is playing up. If the distortion is on more than one channel, you are looking at a faulty part common to both channels. If on one channel only, perhaps something in the pre-amp or power amp sections. Have a look inside, you might find a burnt resistor, which would cause it.

Denon AVR 1706 Powers on display then shuts off lght blinks red

replace all the electrolytic capacitors in the power supply. i had the exact same problem with mine and once i replaced the capacitors it powered up and stayed on and worked perfect.
these capacitors tend to fail as they're of poor quality.
this fault is very common on denon receivers, especially the later models.

hope this helps?

C320 only red light goes on, doesn't switch to green and speakers start humming. None of functions work.


There are failed components in the power supply -to-power amp section.
I can suggest a repair place if I know your area
