Our receiver turns on for a second and then shuts right off. I think it's the fuse, can I change this my self and if so where do I buy them?
Don`t open it yet
check ur speaker wires, try disconnect all wires from back of unit and then try to turn on unit .
if it stays on whit no wires attached than u have short connection at speaker wires .
if doesn`t come on then try to fasten screws at back of the unit ,
may sound like BS but if amp board don`t have good ground connection it can go in protection mode happened to me on RX-V592

I've been having the same problem for 3 months. Checked connections, sent unit out for repair (3x), contacted Yamaha (no help at all) and still the same problem. I've spent over $350 in repairs and I'm very frustrated. I think I'm going to just buy a new receiver (not Yamaha).

it is your protection circuit working, preventing the unit from any further damage to circuitry. you can check first your speaker cabling for any short connections, possibly red/black terminal wires got entangled. if all ok then try removing all speakers then turn on the amp. if still does the same thing turning off then you have a problem with the amp output stage, shorted power output transistrs/driver probably. if the unit turns on normal without the speakers then you must have one or both of your speakers busted. by the way this amp is multi channel, after removing ALL the speakers connected, and does not turn off anymore, put the speakers back one by one and observe if the unit with turn off and on which set of speakers. otherwise if still trips even without the speakers, it is your amplifier that is deffeective, any of the five channels, main, rear,center. let me know result so i can guide you on how you can get it repaired and what will be the extent of damage in case.

I suggest you run self diag. press [FM/AM] key + [Input mode] key and press the [power/standby] switch.
ps prt = power supply problem
dc prt = shorted output or leakly cap in channel
tmp prt means to hot on heatsink
you'll likely have to measure the resistances of the output FETs to find a short,

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

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.
