I have a typical Sony Amplifier that is about 4 years old. The power button which has not changed makes a click when I push it. But the unit does not come on in terms of script or power to speakers or anything. I know the plug works as I tested it. What do you think the issue is?

Re: sony amplifier power
This is usually caused by a blown fuse or a blown capacitor. The fuse would be cheap and easy to fix, the capacitor would be expensive and replacement would be my choice. If you are pretty handy with electronics, unplug it, take the cover off the unit, and look near the capacitor for the fuse. Check the fuse for a break in the wire inside it. You can get these fuses at Radio Shack. Hopefully this is what it is, and will be a cheap and easy fix for you.
Let me know how it goes.

If there is any problem in the output amplifier section then the output repays will not get activated and you will not get any audio. What you have to check is power up the device and listen is there is any click noise comes from the amplifier (relay switching noise). If its not there then the protection stage is not allowing the activation of the relay. If so you have fault power amp stage either left or right.

So the standby indicator never changes state? If so, more than likely, your amplifier has DC Offset(a damaged amplifier inside) which will keep the speakers off, and disable any use of the front or remote functions. If you are interested in having your Sony repaired, please refer to my website, audioserviceclinic.com. You may contact me there. Thank you.
Most receivers will click a few seconds after being powered on. This is the relay that turns on the actual amplifier part of the receiver. This is usually the most typical issue in regards to this. Replacement parts may be available but it could require a fair amount of soldering knowledge. Would have it looked at, at a repair shop to verify.
Try this to isolate where it is coming from. Either the zone amps are defective, which is not likely, or the main amp is at fault. Hard to believe they are mis-wired, they typically are foolproof in this area.
At the main controller, try the two zones that are good and plug them into the 4 bad zones one at a time and see if you get the same symptom. If you do, then it is not the main controller and something common to the 4 zones is causing the issue. If they are wireless, then you my have interference so check if you can select different channels.
Yes, but the wattage numbers are pure marketing and have no bearing in reality or fact. In general, given realistic amplifier power specifications, a higher-powered amp will be a better and safer power source for any given speaker than an under-powered amp since the latter will probably have to go into severe distortion to produce the same loudness a high-powered amp can provide cleanly. Distortion kills speakers.
Since the unit is less than one year old, Sony should repair it under warranty. Also, check the extended warranty parperwork. Normally the seller does not provide the actual warranty, they contract with a service company. That company should still be around. If you are not successful with Sony, please post the exact problem and model number and we'll try to get you up and running.
I discovered that there is a compatiblilty problem between the Bose receiver and the Sony amplifier. If I disconnect the receiver from the amp then the amp starts up normally. Apparently the receiver sends out a dc offset or a "thump" that the amplifier doesn't like and goes into protection mode. I solved the problem by putting a 1 second delay circuit between the receiver startup and the amplifier startup. A simple RC delay on the remote input to the amplifier solved the problem.
