Unit won't turn on. There's power to the outlet but the reciever just won't light up! Sony STR-DE 197 It's only a couple of years old and shows no damage.

Hello Oliver, Question, the Sony sound equipment model, is the
STR-540 or the STR-HD540
Because of the STR-540, I can not find information to see the connection options you have to solve the problem you pose
I wait your answer
Greetings Franco Dosil

Protect will usually show up if the receiver was turned up too loud to the point where the speakers will crackle, the receiver will switch to protect to not damage anything. Unplug it for about 30 seconds and check all the audio wiring in the back to make sure everything is plugged in good and tight and no loose cables or stray pieces of copper audio wire and plug it back in.

protect mode means there is a shorted components inside your reciever it's probably the out put transistors take out the transistors and test it with a multimeter.

Plug a light into the outlet used for the A/C, if the light does not come on when reset then the circuit breaker that provided the power to the outlet need to be reset or replaced.

Check the fuse, Sony is known for its random problems with sound. The one I have you must tap it on the side. Its a flicker switch inside.

unplug,leet capacitors discharge, check back of unit where speaker wire clips are to make sure there are no wire strands touching each other,check same thing @ speakers, try turning unit back on.

I have the same unit. My best recommendation would be to remove all speaker wiring, and try new wiring with another pr of speakers,since the "outdoor " speakers were rained on. the protect mode that the unit went into sounds like it did because the speaker outputs were shorted due to the rain, so ensure that the speaker output terminals are not shorted and dry...also see if output is still availalable at the headphone jack...if it is, the pre-amp section is still good , in which case the protect mode and no volume output out of the speaker jacks may mean that youve blown the ouput trasnsistor finals.
I hope this helps.

Sounds like a grounding problem. If the ground plug isn't missing or loose try plugging it into a different outlet.

Could need a new ir sensor or repair solder connections on the display (ir) board. You can check that the remote is putting out a signal by viewing it with a camcorder, turn the camera on look through the viewfinder and point the remote at it push a button. If it is working you will see a flashing light on the remote.

Power Amp IC gone in your set, replace it.
