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,

What you will need is a phono pre-amp, then you can run into the receiver with a line level input to an empty audio input on the receiver, you can try Radio Shack to obtain one.

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.

The board price won't be cheap. Were they going to replace the board or repair it? It is possible that the component parts are not available from Yamaha and the only option is to replace the board. Other shops may be able to repair the board. What was the original problem that lead them to want to replace the board?
