The unit is protecting itself from a high current situation on the output amps. Either you have a bad speaker or an Amp that is getting ready to give up the ghost. Check your speakers with an Ohm-meter for proper readings (ie 4Ohm speaker should read 4 ohms)

Shuts off itself

I presume when you say it shuts itself off you mean it doesn`t actually come on, It goes to Standby, (Red light). If this is the case, It will probably be the power supply being turned off (Protection mode) by the microprocessor. Have you fitted extension loudspeakers with bad or loose connections? This was a common fault where customers made a bad job of connecting external speakers. I had this once with one set where the customer had a parrot which bit through the cable to the surround sound speakers. Try disconnecting all external connections first, If this doesn`t work, you have fitted speakers and there were taped joints in your wiring, you may have damaged the sound output chip. Other than that, you need an engineer. All modern electronic equipment including TV`s have an inbuilt safety feature to prevent the set from setting fire. It does this by having the computer which controls all the various functions (Including standby) permanently monitor all the voltages within the set. If a voltage is or goes low, possibly indicating a short circuit, the micro detects this and puts the set into standby. Some sets cycle or keep repeating the process of trying to get the set on and then gives up after a certain amount of cycles if the fault does not clear. A good example of this is when there is a very bright screen, the micro could shut the set off thinking the power supply is getting low. Basically what I`m saying is, it`s a workshop job with engineer if non of the fore-mentioned faults exists. Ian

A/C cuts out, restarts at times by stopping engine and restarting

Sounds like the system needs charged. When the pressure drops the switch will shut off the system. Hope this helps and have a good day.

Denon AVR-4802R automatically shuts off in multi-zone mode

i had the volume of the multi-zone tuned too high and was attenuating it in an external control box. Once i took the multi-zone volume down to -25db, the problem went way. My main zone was operating around -35db so did not have the problem.

Turning volume up on my Denon AVR-485 AMP causes it to turn off

Speaker Impedance:
When speaker systems A and B are used separately, speakers with an impedance of 6 to 16 ohms can be connected for use as front speakers
Be careful when using two pairs of front speakers (A + B) at the same time if their impedance is less than 12 ohms.
The protector circuit may be activated of the set is played for long periods of time at high volumes with an impedance lower than specified are connected.

Shuts off everytime i turn it up pass 4.

Speaker wire contact with each other is the problem. Check the back of ALL SIX speakers including sub-woofer. You should find wires contacting each other. Fix that and your problem will be solved.

TV doesn't turn on

When the set is turned on, the computer senses that something is wrong and immediately shuts the set back off. The standby LED will then blink a code, a certain number of blinks, to indicate exactly why the set was shut down. It is possible that your audio output IC is shorted, as this would make a pop or strange noises in the speaker just before the set shuts down, which it does to protect your speakers from burning up. The set should be looked at by a qualified tech familiar with Sony TV's.
