Sony receiver str-av 570 makes clicking noise and displays a flashing p
Sony str-av570 makes clicking noise when shut off for a while. when turned on a flashing p in the display shows up. I hear clicking noise and nothing works. When i unplug the receiver for a while and plug it back in, it works fine. So long as i keep the receiver on there is no problem.

check speaker connections.sounds like the system is trying to stop some thing more serious happening by shutting itself down.a pain yes but saves blowing something up.if no luck,then definately send in for repair
Hi,do you hear any strange noises? If you hear clicking or like wanting to turn on it could be the board that powers the lamp it's called the ballast.It's major symptoms are clicking,electrical sounds,shuts off and on and get the lamp indicator.But if you don't hear any strange noises,tv is around 6000 hrs,2-4 yrs,It's major symptoms are clicking,electrical sounds,shuts off and on and get the lamp indicator, it could be time to replace the lamp.The lamp you need is XL5200 you can find it here:http://www.discount-merchant.com/Sony-Grand-Bare-Lamp-XL-5200-p/sony_xl-5200u_replacement_lamp.htm?Click=48173.Have a blessed one!
Do you hear any clicks? If not, the standby transformer or related circuitry is bad. If you hear 1 relay click...the audio output section is most likely the problem. The first click you hear is the main power relay...and should see display.. the second relay click is the protection circuit relay engaging to let audio to your speakers...if the second click is not heard (it should occur in 3 to 5 seconds) there are shorted output transistors or a shorted output IC trying to blow your speakers with 50 to 75 volts dc. The protection circuit monitors the speaker lines for voltage. They should always read milli-volts only...not even 1 volt.Anyway, good luck
Sounds like faulty psu (pwer suply unit) Amp is going into protection mode. Disconnected all speaker and av wires (only power) turn up volume and see if it stays on. If not psu, sounboard or volume function faulty. If on, connect one speaker L or R. Go to tuner mode to tuned radio station an listen for sounds. If on, connect speakers and av cables one by one and test each one on its own until amp switches off, Investigate from there were problem is. Make sure speakerwires is not shorting out.
Check fuses on unit .Fuses should be on right side of amp .If all fuses are okay.If a fuse needs replacement .Replace with same type and always make sure unit is unplugged .Its possible unit needs repair
first, at turn on you should hear a relay click then a few seconds later a second click. if you should hear the two relay clicks then check to see if you have both A and B speakers on, if you do shut B speaker off. next check the tape monitor switch make sure that it is off. if you should not hear the second relay click you have a problem with the unit and needs to be repaired.
If you do not here a click as soon as the power is turned on, (note you must be in a very quite environment no noise absolutely to hear this) then the amplifier has blown output transistors which are pushing DC current to the speakers.
