Yup I would tend to agree it's probably the PSU... It shouldn't be too expensive to fix, probably an hour or so labour and either parts OR a complete new PSU, in saying that ensure ya take it to a reputable service place.. and get a "quote" B4 allowing to continue.

I had a similar problem with a jvc 8040. when I replaced the fuse it became very obvious that the b1560 output on the center channel was blown (smoke and sparks, always a dead giveaway). I haven't fixed the center channel yet but simply unplugged the center channel board and removed it from the unit. Now everything works fine except of course the center channel. Pre outs still operate just fine so a slave amp could be used for center channel power, or you could just go and buy a marantz amp; I did and then I realized that I was lucky that the old jvc quit.

If you followed the instructions correctly, then the amp must be defective. This is sort of simple.
My generic suggestions:
You have the power, the ground, the outputs to the speakers, and then the input.
Make sure that none of the speaker wires are somehow being grounded. Make sure that nothing is shorted that feeds the speakers.

Not very likely that you can fix it yourself with little electronic skills. You fried the channel you had it connected to. It will require the replacement of a lot of parts in the amplifer circuit. When a channel blows it has several transistors, several resistors, sometimes a couple of diodes and capacitors, and sometimes with the sony amplifers a pre-amp driver IC that will need to be replaced. You will require a multi-meter to determain which parts must be replaced, a soldering iron, some solder, and some solder wick to remove the solder from any bad components that must be replaced.
Any time you connect more than 1 speaker to a channel you risk over-heating that channel and shorting out some components. There are no amplifiers that are designed for more than 1 speaker per channel. I have repaired many sony recievers, including the one you have on several occasions, in the 18 years of working as an audio repair technician. With 2 speakers on the same channel you will draw double the amount of current thru the amp circuit than it was designed for. With 3 speakers on the same channel you will draw triple the amount of current and so on, and so on. I am really surprised that it played for more than just a few seconds with that many speakers on one channel. It must have been in really great shape to start with. I am sorry you did not know this before your party, it would have saved you some money.
Now the good news!
It should be able to be repaired. If all the speakers you had connected were really all on just one channel, you should have only one channel bad. This is a nice receiver as I am sure you must know, since you own it. It is worth getting repaired. As I have stated, I fix these for a living and I would expect the repair cost to be around $125 to $150 if it was taken to the service center that I work at. I can not be certain what another shop would charge, but this is a pretty good estimate considering I do not have it right in front of me to troubleshoot. Some shops are more honest than others, and there is always the chance that there may be more damage than what I would anticipate, or even less damage than I would expect resulting in a cheaper repair.
If you want to take a crack at fixing it yourself I would be happy to guide you thru it, but you would need the proper tools as I stated above.
I hope that you have found this information helpful, and if so, a rating of "FixYa!" would be appropriate and very much appreciated. After all, it is the only reward we get for offering people like yourself this free information and help.
Let me know if you want to try and fix it yourself, or if you have any other questions I can help you with.

Hi there get a multimeter place across mains input on transformer,FIRSTLY DISCONNECT AMP FROM MAINS,set your meter to contiuity ,if good you should get a low ohms reading (resistance),then check the secondaries (output of transformer) either 3 wires or four going into amp board..if readings acroos all wires are low ohms then transformer is good if one is open ,transformer has had it ...hope this helps
