SOURCE: STR-DE475 receiver flashes "PROTECT" when turned on

Protection is usually a sign of overheating or something is wrong at the power amplifier's output.

Theory: Protection is a delay and sometimes an internal test to allow the electronics to stabilize during power up before they are allowed to interact with the speakers. The most common cause of it remaining ON is that a speaker cable pair is shorted. Some isolation is required...

1. Turn the Power OFF.
2. Disconnect each set of the speaker wires that are directly attached to the receiver. Mark them so you remember where each one went. pay special attention to which conductor is on "+" or "POS" and which is on "-", "COM" or "Ground". You may elect to disconnect them one pair at a time if your sytem is complex and you don't want to lose track of where things were.

Turn the Power ON. Is the "Protect" indication gone from the display?
--------------------
If YES, you have a shorted speaker wire or speaker. To isolate the specific cause:

1. Turn the Power OFF.
2. Attach ONE speaker wire pair at a time and test it by turning the Receiver ON. When the "Protect" light returns you have isolated at least one of the cause(s). Disconnect the defective speaker cable and continue isolation of all speaker cables. Visually examine the cable at both ends for frayed wires that could touch each other or contact metal on the receiver or other objects.

To isolate further within the cable/speaker pair - disconnect the speaker end of the cable on the failing path. Try another cable that you know works, or at least one that doesn't cause Protection to stay on.

If you're electrically savvy and have a Digital Volt/Ohm Meter you can troubleshoot the short(s) with it.
-------------------------

If NO, there is probably an internal problem.

Is it solid or does it come on after the Receiver has been ON awhile.
It could be overheating.
Is the unit hot to the touch?
Is there a cooling device (fan)?
Is it stopped or clogged with dust?
Is there adequate ventilation around the unit for air to flow?
Clean any ventilation slots on the top and bottom of the unit.
Avoid stacking components that produce heat under an amplifier or receiver. Their heat rises. Also keep them away from other heat sources like like home heating vents and radiators.

Problem solid and NOT related to the speakers or heat: internal malfunction.

Let me know.

Why does my Sony STR-K750P AV receiver automatically switch to Video 2?


Some models of systems will switch to a new source automatically if the source sees a new signal coming on. Try disconnecting the device on your Video 2 to see if this is the case.

I have seen the IC or component(s) in the switching circuits become defective and cause unpredictable or faulty operation. This can also be a fault condition you are seeing.

Have a sony trinitron tv which turns off automatically and sporadically on average every 15 minutes


Hello
Most of the sony Tv power supplys are based on STR type regulators. Regulation of an STR is very accurate and if any overload inside the ciruit board of the TV, will be sensed by the STR and will shut off all the supply to the system itself. From your complaint we understands that there is some sort of short, not a direct short, is in your tv. Usually it may related to horizontal output transistor. At first it will work fine, but as time pass on, it will get over heated, passes more current, and place a short like circustance to the power supply rail itself, and as described above, STR will sense it and will shut down the system. After some time, say after 10 or 15 minutes, after the heat generated has gone off, the TV will again switch on, and the cycle will be repeated. You just call a technican and keep this in mind, and ask him to repair the same.

The digital sound is off after 1 houre str de sony str de 485


It sounds like the receiver is either failing or going into a thermal protection mode.

There should be NO reason why the input source (digital versus analog) should make a difference unless you play the digital sources obscenely louder than the analog ones.

If you suspect heat, you should be able to feel it.

Can you verify that the digital sources ONLY do this?

Get a headpone to rca cable (radio shack or best buy) and use any input on the rear of the receiver except phono. You will need to turn the ipod to near max volume.

Stops working after a few mins with cd player playing


One of three things: speaker wire short, shorted/or blown speaker, or a bad output chip. First and easiest way to check is to disconnect all speakers, turn it on, turn it up, and wait. If that's ok, begin connecting one speaker at a time with the unit off, then turn on and play. When you get to the speaker or wire with the problem, it will short and go into protection. Disconnect all speaker wires again and only hook up the speaker that shorted the receiver and test. If it shorts, swap speakers with the same wire and test again. If a different speaker on the same wire causes the unit to short, replace the wire. if it doesn't, you need to test the speaker with a multimeter or disassemble if possible, check the wiring internally on the speaker. Check the impedance, should be 8ohms or 6ohms depending on the drivers. then check for resistance. If your meter says 1... it's shorted and needs to be replaced. Hope this helps

See add details


Since the receiver eventually works, the delay circuit is failing. This is a circuit that allows the power supply to settle down before kicking in the output relay. This prevents the "pop" that was sometimes heard on older units. This should be a simple and inexpensive repair probably requiring the replacement of a couple of small capacitors in that delay/protection circuit.
