I think you need to bring back your receiver to shop where you buy it
i think it still at guarantee period and you can claim it
and you will get new receiver

How do I reset a technics sa-gx350 receiver unit

Don't know that you can actually reset this unit like the new digital receivers. It does have protection circuitry that will shut the unit down in case speaker wires are shorted or if speaker impedance is less than the indicated rated impedance of the amp. do the following:
1. Turn off power and unplug from wall.
2. Check all connections and correct if needed.
3. Turn back on after 1-2 minutes.
If unit is still in protect mode you may want to unplug everything from the unit and then power back up to see if the problem is internal or external. If it powers up correctly then the problem is external. Power back down and plug in one external item at a time and power back up between connecting each item to see which item causes the receiver to go into protection mode.
If problem seems to be internal I'd recommend taking to an electronics repair shop if you aren't comfortable with taking apart to check fuses, terminations, etc. There may be a 5-amp fuse in the power plug head also.

I have a Onkyo TXSR-574 Receiver. After playing for a period of time (its never consistent) the receiver will cut off. You can cut it back on and it will play about two seconds and cut off again. It's...

The amp is protecting itself from something either real or perceived by the protection circuitry.
Check your speaker impedances to make sure they are all what they are supposed to be (IE, 4 or 6 or 8 ohms depending on the speakers and arrangement).
Feel the amp to see if it's warmer than it should be - blow any dust out of the heatsinks.
when it cuts off, try spraying freeze mist on the components until it turns back on and behaves - accurate use of freeze mist can diagnose a thermal problem easily.
Look for bulging or leaking capacitors anywhere in the circuity.
Failing that, it'll have to go into a shop.

The receiver always goes into protect and im not sure why, it will work for a short time and will then go "off line" and shut off

Cool down first the unit for about 5mins.Disconnect all input and the speakers connected to isolate the problem. Power it on then observe while playing it naked. If the symptom still there then I've suspect that you have a fault on the FF: 1. Power supply - might have an unregulated supply caused by leaky capacitor. 2. Pre-amplifier circuit - might be faulty. 3. Output IC - IC is leaky which overheat after a minute which trigger the unit to protect.
This is not diy and need to send to repair shop. If the symptom gone after you played it naked then I've suspect the ff: 1. Short on speaker wire. 2. Short on speaker voice coil. 3. Short on input.
Thanks for using fixya.

See add details

Since the receiver eventually works, the delay circuit is failing. This is a circuit that allows the power supply to settle down before kicking in the output relay. This prevents the "pop" that was sometimes heard on older units. This should be a simple and inexpensive repair probably requiring the replacement of a couple of small capacitors in that delay/protection circuit.

Reciever turning off.

You have a short in the speaker wiring. Simply put, the pos and neg (red/black ends) of your speaker wire are most likely touching somewhere. The receiver has a short protection circuit that keeps you from blowing the receiver or your speakers. Either try re-cutting the ends of the speaker wire, or if that doesn't remedy the issue, buy new speaker wire.
