My Sony STR-DE597 receiver makes a clicking noise when you hit the power button but nothing comes on.


Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on; or it may turn on but produce no audio to the speakers.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; 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 'nekkid'. 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 and competent hands-on tech.

Check for loose speaker connections at the speaker as another possible root cause for intermittent shutdown.

On display appears PROTECT. can not clear data. how to solve it? thanks


check all the speakers connections for short circuits

unplug from wall
and
unplug all of the speakers and extra components and turn it on to see if the message disapears

if it does one by one start plugging that speakers back in
unplugging from the wall every time you add a speaker
(just in case the reciver only realises there is a problem after it shuts down)

if you find that after pluging in a speaker and when you turn it on check the wires for cuts or short circuits and check the speaker itself replace it with another and see what happens

My receiver has been in the box since new. I just hooked it up for the 1st time and I cannot seem to get the unit to see the digital input (which is suppoed to be automatic. Vincent


Check your settings in the main menu of the receiver. Make sure it's set to "Auto" If you still have an issue, post a comment and I can help you troubleshoot further.

My receiver changes to "protect" then clicks off


Since you had to change the fuse to get it to power on, chances are you have a damaged receiver. You can try resetting the system (instructions below) but I doubt this will provide relief. When a system is doing what yours is, it is more often than not a sign of a short in the system causing excessive power consumption. Many times such problems in the final amplifier section, in the form of shorted output transistors. This most often happens from running with the wrong impedance load, shorted speakers connected, loud volume with inadequate ventilation (high heat conditions) or running the receiver without speakers connected.
Try resetting using the front panel controls. Power off. Then holding the 2 channel button down, power on. You see an abrv reset message. If after doing this you still have the same issue, it's time to investigate repair facilities or due to possibly high cost of repairs simply retire the unit and get another.

Audio protect keeps turning off my receiver (sony STR-DE597)


That is the common symptom of the defected STK-IC in power amp.section that busted already or just a loose connection.First try to resolder the pins of STK-IC and also all component parts joint in power amplifier section if its works! if not that is the time you replace it, so it works normal again.

Hope it may helps you...

I want to find the isntruction for ow to turn on a tv


The instructions are available from Sony's website, but generally you can:
Press the Power button on the TV itself
Press the Power button no the remote.

Perhaps you might want to rephrase the question.

Dark display on Sony STR-DE597 receiver


Check for bad solder connections on the display itself. If none use a voltmeter and check dc voltage on the first and last pins of the display. should be about 20v dc. If you don't have the dc voltage check for a bad transistor or resistor in the power supply. It could also be other thing but this is where you should start.

Try a complete RESET by completely switching OFF mains power and leaving for at least 40secs. before commencing a new setting-up procedure.
Let's know if this does work it back to normality!
