Question about Sony STR-DA80ES Receiver

Str-da80es sony receiver

Have had this receiver for several years, and out of nowhere (no moves, storms, etc) I can't even power the unit on.... is it just how these receivers "die" so to speak, or does it need to be reset somehow??? I did not see anything in the owners manual under trouble shooting that would address this issue. There is just no reaction when I hit the power button.

Sony receiver (STR-DA80ES) is in protected mode and stays there. Might need new amp board (part number A-4403-068-A)

Or it might be something simple. Since you don't reveal the steps you've taken to isolate the problem...

Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.

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 'naked'. 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.

But you probably knew all that.

Search engines find that part if you REALLY want it:

DA 3ES powers on, shows the appropriate connections i.e. opt for directv playstation, etc , but has no sound for any sources. Several of the orange lights remain lit, audio split, and others and the...

Great testimony for those Monster surge protectors, huh?

Did the failure coincide with the storms? If so, stick a fork in it, it's done.

Just the same, if you really want an assessment as to damage and cost you need to have someone knowledgeable give it the sniff test in person.

No one out here can do that.

My reciverer says the word protector

The Word "Protecter" is you have a shorted Speaker or Wire to Speaker, or the Sony has a blown Power Amplifier

Powers up, all lights buttons seem to work, but no sound

This can happen. Lightening causes static charge that can be picked up by speaker wires. It is possible ONE of the amplifiers has failed.
To check, have the room quiet. Turn on the amp. After 5 to 10 seconds there should be a nice solid 'CLICK' from inside the amp. If there is no click, the unit is in safety mode. You will need a service shop.

Sony STR DE-445 unit powers up but no sound

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.

Receiver blew and flashes "protector" at all times. Disconnected speaker cables and still no change.

A problem has been detected internal to the unit and it has been shutdown to prevent further damage. The typical cuase is shorted output transistors or a defective voltage amplifier IC. Either repair will run about $25-$40 for parts.

Sony STR-D460Z receiver

I have had this problem several times with Sony receivers in the past. The issue may be frustrating but these receivers are idiot proof. It is doing you a favor by tripping and not setting your house on fire as well.

Many things like improper wire crossing or touching due to too much of the insulation stripped off can cause this. Thunder storms and power surges as well have been known do this to Sony receivers.

Unplug the unit and remove the cover. Look for any blown fuses as sometimes this is the problem. Take the fuse to a Radioshack to find new ones. However, it is likely you will need to take it in for repairs. This usually costs around $100. Find a local electronics repair shop in your area ( "TV Reapir in the yellow pages") or call Sony to send it to them.

I hope the latter works.
