The problem is that the output transistor(s) are shorted causing the unit to shutdown in what is called "protect" mode. This is a common failue and should be easily repaired by a service shop for about $25-$40 in parts plus labor.

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.

you can check them with a ohm meter, hook it to the wires that you hook to the reciever and if you get a reading it is good if no reading it is bad wires

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

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.

sony DA90ESG I have a Sony Receiver DA90ESG i have it for a while and its one of the best receiver i ever come across. Never the less i was playing it the other day and i heard a pop in the front speakers i was using the MD moode witth regular audio cables. I notice some of the displaying light were dim like it was not getting enuff power. After i check the wires ect i turned it back on the display said ' OK ' It was ok for a while and then the other day i was playing it again and the sound went. The same display light was dim and the light on the volume went off but the display was up. I tried checkng the wires and everything seems to be ok. After i left it off for a while and turned it back on it played for a short time and then no sound. I saw an unusal display it reds ' AC-3 RF' when i put the recevier on tuner the sign comes of but still no sound. I turned it off again for a day and it start playing again but after 5 mins the sound went again and the same display comes up again AC-3 RF' Could you tell me if it some thing that iam not doing or should b doing, or should i give it out to be fixed. PS When the sound chips out and u try to open the lever it just go up and down repeatedly at a slow pace and wont close, but when the receiver starts to work the lever moves freely and closed itself. It seems like a power problem not sure but any help will be gratefull dont want to buy ny other recevier. Regards Desi Wilmot desilee2000@hotmail.com
