When problem accures in Amplefier section, protection actviates to protect speakers and further damage in unit. I think, Amp got defective in your system and needs qualified service person.

The unit has DC Offset, meaning a damaged amplifier. This issue will not allow to unit to turn until the damaged is repaired.

When i turn system on stays on for 5 mins then shuts down automatically rca rtd209


Something is overheating which is causing the unit to shut down to protect itself.

Try disconnecting the speakers and see if you get the same result.

If you do then the fault is with the Power Supply, if not then the fault is with the Amplifier.

I have an audio receiver that powers up and the shuts down. I've replaced the power cord (due to rabbit) and the fuse. But continues to shut down??


Why did you replace the fuse - did it burn out or opened? It's probably shutting down because it's detecting an overload. Inspect the circuit board for any shorts. I recommend having a repair shop isolating the problem. If it does blow fuses, then there is definitely a shorted transistor on the final amplifier output stage. Otherwise, if a fuse is shorted you don't need to replace it because it's suppose to be shorted.

Power turns off


Protect mode will kick in whenever a fault is detected.

You get the unit not powering up, and sometimes you hear a clicking noise, that is the protection switch that keeps shutting down the unit.

Causes that can start protect mode are:

Electrostatic harges on internal circuits.
Leave the unit unplugged for power for one hour or so, this will allow discharge.

Bad speaker wiring.
Check speaker wiring, try unplugging and plugging back, or start after removing one speaker at the time.

Internal fault.
Internal fault is the natural cause for protect mode. If all the above did not work, then the problem is a blown component or an internal fault. In this case the unit must be taken apart , tested and repaired by an experienced person.
If the unit is less than one year old, or if you want to get service, call Sony at the phone number listed on the product documentation.

Protect mode shuts down the receiver


If this happens only when connecting the receiver, chech the receiver cable. If the cable is fine, receiver connector at the back of receiver is faulty.

Hi,

Take every single cable out of the unit, now power on the unit.

If the power protection still shows then there is an internal fault, usually a short or a component defect.

If it powers on ok, switch off and insert 1 speaker at a time and power on the unit until the protection mode comes on again, the last speaker you have put in has overloaded it for some reason, also as you are trying each speaker use the volume and bass controls to see if there is an internal overload.

Thats as much as I can offer you until you narrow the fault down to the unit or one of the speakers.

Cheers

Protection means the unit is detecting a short somewhere. Disconnect speakers and components and attempt to power on the unit again. If it will power on with nothing connected, repeat the process (turn off, connect something, then power on) until you find the bad component or speaker.
