Try opening up the unit and giving the insides a good cleaning with a can of compressed air. That might help.

I have a Sony receiver model Str - de 435 it constantly flash Protector and I tried everything to fix this any ideas


The protector indicator usually indicates that one of your amplifiers has shorted output transistors. This is not a user repairable problem and the amp will have to be taken into the shop for service.

It says protector mode what does that mean


If PROTECT , PROTECTOR or a P is flashing in the display of the A/V receiver, there may be an incorrect connection or an improper setting. Try following these steps to resolve this issue:


NOTE: Because each of these steps represents a possible solution to this issue, check the A/V receiver status after completing each step.
  1. Check the speakers and speaker wires for proper connections.
  2. Reduce the volume level. IMPORTANT: If the A/V receiver is used at maximum volume level, it may enter the PROTECT mode. Maximum volume listening will cause the A/V receiver to run very hot and may drain the output capacitors.
  3. If applicable to your model, disable the surround sound option if both the A and B speakers are being used simultaneously.
  4. Ensure the top of the A/V receiver has proper ventilation to keep it from overheating.
  5. If the message only occurs when using a DVD player, the sampling frequency may be set too high. IMPORTANT: Some A/V receivers provide compatibility with the higher sampling frequencies through alternate connections. Consult the owners manual for specific information.
  6. Unplug the AC power cord for approximately 1 to 2 hours to reset the output transformers.
If the issue is still unresolved, service may be required.

I was listing to my stero and it said protector and I cannot get my big speakers to work, its an older onkyo 857c 120v 60hz 3.6a and there is no reset button


Disconnect the speakers and see what it does. If you were playing it very loud just prior to the failure it possibly overheated or blew up a speaker.

Make/model and any other clues you know would be VERY helpful.

Hooking laptop to onkyo sr604 through hdmi no sound through stero


hdmi is video only

you will need to use the rca/phono inputs for audio.

you will need a stereo mini jack to steroe rca/phono

use the i/p marked aux/cd/

make sure the volume on the onkyo is turned DOWN before connecting any new input source.

The output from most laptops is designed for headphones so you may need to adjust the volume on the laptop DOWN as well.

Perhaps start off with laptop at 30% and the amp DOWN then increase the amp until you can hear the laptop sound.

To get good quality audio from a laptop you would be beter off with a USB sound card.

hope this helps, thanks for using FixYa

if this is helping please vote.

This amp wwhen turned on, dosplays 'PROTECTOR' on teh display, what is this telling me?


Disconnect all the speakers and unplug it for 5 minutes. Then turn it back on without any speakers plugged in. If it doesn't say protector, then you either have a shorted out speaker or wire. The amp is in protection mode which is designed to keep it from burning up. If it still says protection, then it will need to be repaired as it is too late.

Flashing protect


the protector comes on to keep the amp from further damaging itself or the speakers. The buzz you heard was probably 60HZ line buzz from the main DC supply conducting full current through one of your speakers through a damaged amplifier transistor. Your stereo will need professional repair. The protect circuit basically opens the speaker relay (and sometimes shuts down the unit) to prevent this DC voltage and current from getting to your speakers until the problem is corrected.

When i turn up the stero the power turns off and the red standby light flashes till i turn it back on


Firstly i would disconnect all speakers and turn amp up if still does it then there is an overload in amplifier anbd needs to be repaired..

If not then connect speaker 1 at a time and try amp volume again,you could also get a multimeter and check across speaker terminals on boxes for different resistance readings..

Protector flashing


Protet mode is a special diagnostic mode that starts when a fault is detected.

When in protection mode the unit is prevented from starting by protection circuit, so to prevent further damage.

Check the speakers and speakers wiring, a contact in speaker wires, or faulty speakers can send the unit in protection.

Try unplugging power cable for one hour or so. then connect cable back and see if you get rid of protect state. Sometimes accumulation of electrostatic charges inside circuit capacitors can kick in protect mode. In that case unplugging the unit from main for some times can get rid of electrostatic charges, and reset circuits by draining power completely.
If that was the problem, you will not get Protect when plugging back power cable.

If you do all the above and still get Protect, then there is a real fault.

In that case the unit may be disassembled and tested to find the fault.

If that is the case I suggest contacting the manufacturer at the number listed on the owners manual, or asking a quote on repair to a local technician.

No sound


The only fuse on you stero is for power it's a 6.3 amp 125 volt it'on the main board. I have the sam problem I found a resistor on the board that controls the power amps on the heat sink. A lab here charges 35 dollar bench charge and if you want them to fix it they will apply it to the job. I own the same model and i went to circuit city they had lot of different system on sell. So before i put that in to an old system i'll buy another one
