My yamaha_rx-v457 is automatically switching off when i turn on

SOURCE: Yamaha rx-v456 av receiver, shut down with optica cable

Does it work without PS3 attached?
When receiver turns off, it is usually due to badly connected/configured speakers. Try powering on the receiver without speakers.

Had same problem. Display would read, "Check Speaker Wires". Rear speakers were shorted by a carpet nail. Works fine now.

Does the reciever have separate speaker switches?
Try turning off the speakers and turning on the amp.
If it doesnt have speaker switches , make sure ALL the speakers are connected at both ends and try turning on the amp again.

Set your TV, Sattellite receiver and audio where you want it when you turn on the set. Then hit the Scene button named "TV" and hold it down till the yamaha receiver says set complete and it will turn on to HDMI 2

What speakers you have connected? This receiver supports only 6 and 8 ohm speakers (not 4 ohm). Also check if the ohm settings are correctly set in Advanced Setup (in standby press on the front panel STANDBY while holding STRAIGHT button). In this menu check the setting SP IMP. (speaker impedance) if it maches your speakers (6 or 8 ohm).
Disconnect all inputs and also all speakers. With nothing connected, try to increase the volume. If it still will power off, the unit is probably faulty and should be repaired.
If it does turn off only with speakers connected, check the speaker wires and the speakers, the problem will be there.
