Why is my yamaha surround sound stereo system shutting off right after i turn it on?

Sounds like the protection circuit has been tripped and won't stay running. You should take it in to a repair shop, it shouldn't cost a whole lot to fix.
 
it is overheating or has overheated, or is just effed. have it serviced. oh that's right, nothing gets serviced anymore in this throw away world we live in.

buy a new one.

Could be a short circuit. Most likely place is the speaker wire terminals. Sometimes vibration can cause a stray piece of wire to make contact with an opposite terminal. The stereo will shut down immediately to prevent damage. If you have speaker on/off switches that can be used without the power being on, turn them off and then try the power. If it powers up OK, turn on speakers and see if it shuts down. If you don't have switches check the terminals themselves for stray wires. If it doesn't power up, chances are the problem is with your amp, and internal. That will likely need a tech to fix.
 
First, make shure all of your speaker wires are not
damaged, or shorting out. If you couldn't find anything
wrong, disconnect all of your speakers, making sure to
mark each one so you can hook it back up the way it
was. Try turning it on. If it stays on, you have a bad
speaker. Turn it off, and connect one speaker. Turn on.
Did it stay on? If it did, Repeat this step until the unit
will not stay on. Now you know it is either the wire
going to the speaker, or the speaker, itself. Second,
make shure your Power Amp. is in a well ventilated,
cool dry place. If anything was spilled** into the unit, it
may be toast, or if you feel real brave, take the case
off and inspect it for water mark(s) and / or component
damage.** If something did get spilled into it, you can
take it apart, and wash it out with a solution of Tide,
Ammonia, and Very Hot Water. With a long bristle 2"
paint brush, use the brush in a scrubbing action to
remove any syrup; Rinse with hot water. Use
compressed air (no more than 60 psi) to blow dry
the unit as much as possible. If you can find some
desiccant, place a pack (optional) inside the unit.
Let stand in a warm, dry room for at least a day.
Use a floor box fan to blow in it so it will dry evenly.
Then, plug the unit in, without any thing connected.
If it stays on, you are good to go! I hope this helps you
Troubleshoot, repair, and save the unit from the scrap
heap / bone yard / land fill. Feel free 2 **e-me! I wish you
many hours of listening enjoyment!
