It says protect on the front screen

My onkyo stereo reciever blew a fuse, we replaced it. It made a popping noise, we tried it again, the power does work on it now but it goes back to saying "protect" on the front screen.

An amplifier goes into protect when it detects a load with too low an impedance. If it displays protect with no speakers connected at all, the amplifier is damaged. If not, reconnect speakers one at a time (while the amp is off!) to determine the cause of the fault.

It may be as simple as a single strand of copper wire shorting between the positive and negative terminals of a connection.

I have four Bose 161 speakers and an Acoutismass 5 bass unit (original cubes are bad and replaced with the 161s). My Onkyo receiver started turning off and going into protect mode recently. Bought new...

you're going to need a ohm meter (good electrical testers have them) and make sure ohm ratings from speakers match the ratings for your receivers. Sounds like to much resistance for receiver(s)

Iassume you mean you hear the buzz independently of the audio program - simply connecting the cable causes the buzz?

If tanything in the mix is powered from different AC sources you may have a different ground potential. Sometimes manipulating the orientation of one or more ac plugs will solve hum problems.

Speakers dead.

Measure resistance of the speakers input with a tester, it should be 4-16 Ohms, if it's 0 or infinity, the coils are burned, and you will need to repair or replace speakers inside.

You have an overload somewhere which is causing the fuse to blow. They are mainly caused by shorted semicondutors (acting like a piece of wire instead of their job). Look careful around you might see damage or burnt parts.

My SW 22HT Kenwood subwoofer stopped working.The fuse was bad it was replaced and the new fuse blew again

The reason the fuse blew again is that an overload has occured. It could be a faulty part in either the power supply section, or the amp section. Follow the curcuit from the fuse, be on the look out for damaged, burnt parts, suspect anything on a heat sink.

What could be causing my Powered Sub Woofer to make crackling noises when stereo is on or off?

Model specification would help with this, but it could be dirt (or fur if you have pets) in the circuit. This is to assume that the unit is in a standby mode rather than off or unplugged. If the subwoofer is a powered sub, then the problem is more than likely in the sub. Verify this by unplugging the cable from the main unit and see if it still crackles. I would need a Make/model to diagnose any further.

Check the capacitor, if its swollen or rusty it needs replacing, also check the fuse.
