Question about Sony STR-DE335 Receiver

1 Answer

Protect I wonder if the previous posters solved the protect problem. I downloaded the manual--the solution was the check the speaker wire which I already did. I had a problem with the over stripped wires touching. I rearranged them and turned the radio on it starts out OK but within second and before sound the protect message appears. Have I ruined my receiver? What should I do? The manual does not offer a reset that I could find. Just tells you to examine and rearrange wires and turn on. There is mention that the wires touching can cause damage. Is this thing now effectively dead. It is several years old but I don't want to buy another and it did give me years and hundreds of hours of great operation. Also I had my 5 disc (sony) dvd attached at the time. Does that mean I have a problem with that, too?

The main purpose of that "Protection" mode is to save the electrical circuits placed inside of the amp. Therefore; I think even if a case of short circuit caused by touching wires can not damage your amp completely but maybe a bit. You had better contact with a Sony service which is close to you. The second point is that your 5 disc Sony dvd must be fine. Don't worry about it.

My headunit (KIV-BT900) is stuck on protect "mode". I've already tried resetting the headunit to factory settings but to no avail. When it powers back up "protect" keeps flashing on...
Check all speakers and their wiring for shorted wires, either shorted togeather or to any metal part of the car.

TX-8211 FM Stereo/AM Receiver All has been fine
make sure that somehow the wires didn't get loose from the speakers in the back. Protect means that it's overloaded. Did you change the plus wires with minus wires maybe. Check to make sure all the wires are good.

When turned on it says protect. instructions says that its a speaker short but i've checked and its not...please help
Hi,

Just as you already know, the receiver will go into protection mode when there is a short in the speaker wires or the amplifier was overloaded. verify that none of the speaker wire connections are loose at the back of the receiver or at each speaker. And verify that none of the wires are making contact with each other.

If it is, then remove the speaker wires and connect them again properly. After disconnection g the speaker wires, unplug the receiver for 10 to 15 minutes. This will make the overload protection back to normal

Try this and let me know. I hope this would solve the issue

Thanks

Amp powered protection on no sound
Disconnect the speaker wires and test again. If the protection light goes out, check your speaker wires at the amp and to the speakers. re-connect speakers one at a time and test until it goes into protection or your problem is solved. If a speaker connection causes the amp to go into protection, test that speaker with a meter or put it on a different channel. may be a blown speaker. If you need more help, post a comment and I can help you troubleshoot more.

Receiver turns off shortly after powered on & displays "PROTECT"
are any other devices sitting on top of this unit? if so it could be an overheat.

If you have pets make sure the wires are not chomped on this can cause a fault.

Also make sure you have nothing other than the factory default speakers hooked up to it.

here is what the users manual says
im going to sum it up for ya. if it says protect that means you have a short circuit please unplug the unit resolve the short circuit and plug back in....... here is the link To the users manual



http://www.docs.sony.com/release/STRDE485.pdf

once it is opened as a PDF document go to the search/ find area and type in "protect" and it will say the same thing.

somewhere you have a short your going to have to follow all the wiring again and look closely

PLEASE HELP
Posting solution to mark this as solved (even though poster already found solution):

Go into Settings menu, select Audio, and speaker output settings. The best is Auto, which will use the built in speaker only if headphones are not plugged in.

Sony STR-DE335 Bass hum I have an STR-DE335 which had been sitting in storage for some time and I have recently pulled it out to use as a cheap PA amp for a speaker system I am building. The amp works fine except for there is now a low frequency hum coming through the speakers. It is only just noticable without the 'bass boost' option turned on, but with bass boost turned on it is quite loud. The strange thing is is that there have been a couple of times during my testing of the amp (maybe around 5 hours now) where it has stopped humming and I have been able to use the bass boost function with no hum whatsoever. But then after turning off the amp and then turning it back on again later, the hum returns =( I'm thinking it might be a loose connection, although I cant seem to replicate the problem by gently bumping the amp..
