Dear friends,
Just a few hour back my YAMAHA YHT 299 switched off automatically, while we were watching movie. It's AVR did not switch on thereafter either by remote or by push button on AVR. I checked all the things and established that there is something wrong in the AVR.
On referring troubleshooting section of its manual (Page 68) it says that -
Problem: Power does not turn on.
Cause: The Protection Circuitry has been activated three times consecutively.
Remedy:As a safety precaution,the capability to turn on the power is disabled.Contact your nearest Yamaha dealer or service center.
This made me worried a lot but after googling a lot I found following solution on the internet, which I am sharing here -
Plug the power cord out. Plug it back in.
Press the following three buttons at the same time for 5 seconds:
Power key (1) + Info Key (4) + Tone Control key (12) (The numbers in bracket are as per front panel picture given in manual at page 7)
And Voila, The receiver switched on. (I did this after disconnecting all the speaker, HDMI and all other cables)
Now I would like if any expert can tell us what causes the Protection Circuitry to activate and what precautions must be taken to avoid this.
