I'm not familiar with this model but is the receiver has an amplifier combined, if so first check for a short circuit on the outputs (speaker wireing), if not combined with an amplifier check the audio cables for shorts too.

If all the cables ar OK than i suspect a power supply problem you need a good tech. for that...

Good luck!

The question is when does the light come on, immediately upon turning on the unit or after turning up the volume? See the link below for an explanation of protect mode. Update this with more details and I'll be able to provide more detailed repair estimates.


Thanks,
DAn

Sony GX800ES protector


Make sure none of the speaker wires are touching each other. If they are, it will short out the stereo which triggers protection mode and cuts out all of the sound.

It keeps blinking protetor


The protector circuit protects your amplifier from shorted speakers . One of your speakers , or more speakers are shorted out . To figure it out easily follow these instructions . Turn the unit off . Now unplug all of the speaker wire connections from the back of the unit . Turn the unit on . Make sure the volume is turned all the way down . The protector light should not light up . If it does , the problem is inside the unit itself and we'll have to be repaired at the shop . If the protector light is off than continue on as follows . Connect the speakers one at a time to the unit . Each time you connect a speaker , turn the volume control up and back down making sure the protector light does not come on . When you connect the bad speaker , the protection light should come on . Whichever speaker makes the lights come on when connected is the bad speaker and should be replaced .

It flashes the word - protector


Hiya,
Disconnect all speakers at the receiver and power it back on. If it stays on, check all speaker wires and speakers for shorts (touching wires). If it cuts out, it needs to be serviced.

After a power surge my DVR-625 receiver keeps powering/cycling on and off between TV 1 and 2. It never comes on so that I can get a signal.


You will need to unplug your rec and bypass any surge protectors, if you still have teh same issue tehn call 800-333-3474 to have your recr replaced. it is a very common issue.

Message "PROTECTOR"


Disconnect all speakers at the receiver and power it back on. If it stays on, check all speaker wires and speakers for shorts. If it cuts out, it needs service. If you need detailed troubleshooting help on this after testing receiver without speakers connected and it passes, post a comment and I can walk you thru it. Hope this helps.

Every time I try to turn on my onkyo receiver it turns off instantly


the reason why the receiver probably keep turning off is that the systems come with overload protector to keep one from burning or short the systems out so it shut its self off. make sure you have the speaker wires is connected properly, its very important that you do although the receiver has 0% tolerance when it come to speakers hook up. positive from speaker to positive connector behind reciever; same as negative. double check all speakers wires. repost if that not an issue

Keep getting message protector


if all connections and speakers seem ok the problem is internal witch can go from blown power supply to shorted output devices and everything in between , and as always look for repair shop in your area, do not attempt to do it yourself, firehazard and electric shock are the things we all want to avoid ;)

Dish ViP622 keeps crashing - on 6th unit from Dish network


the 622 receivers are very sensitive to static electricity build up, if you have been through more than two receivers i would demand having a technician come to your home to check grounding of your dish system, while he is there he will also check the grounding where you plug the receivers in, i suggest not using any surge protectors/power strips and, as debmaldo did, try different outlets, if you have a very high end surge protector, it should be okay but for troubleshooting purposes try a different wall receptacle

Check all your speaker connections and make sure there are no shorts where any of the negative wires can come in contact with any of the positive wires.
