Ok this means the AMP is in protection mode!..most likely the cause is a short in your wireing from the speaker wires! check all wires going in and out of amp! Look for stray wires touching metal or other contacts! (If this does not fix it the short may be inside of amp!
(This has nothing to do with a fuse!)

THANK YOU!

PROTECT means that the amp detected a short circuit on the speaker output, and rather than cook itself to death it switched off the output channel(s)

Unplug your speakers and turn on the amp. If the PROTECT light is still on, then you've blown a fuse (which might be inside the amp)

If the PROTECT light does not come on, then check your speaker wiring and speakers. If you have access to different speakers and wires, try swapping them out to see if you can isolate the component that's failed.

This means that there is a short detected on one of the amp outputs. Try disconnecting the speakers from the back of the unit and power on. If fault still persists then likely you have a bad output ic or FET (transistor). If fault goes away after removing speakers then plug them in one by one to see which is the culprit.

Want to use my current speakers with a new surround sound system. Current system is 5.1 channels, rated at 100w per channel @ 8. Ohms. New System is rated 145watts, 5.2 channels at 6 Ohms. Will b ok?


Hi Ronald.
8 Ohm speakers will work just fine as replacements for the
6 ohm speakers. When fitting speakers you need to consider
The power handling capability. The impedance and the frequencies
involved. Power handling is expressed in wattage ie 100W.
Unfortunately this can be expressed in rms, max or peak music. The rms value (root mean square) is the only really relevant figure as this is the continuose handling power at 1 KHz. The impedance
is the resistance that the amp sees but is not a dc resistance and
varies with frequency. The lower the impedance the more power
will be drawn from the amp. In the event of a short circuit across
the speaker the amp will try to deliver infinite power into an infinitly
small load in an infinitesimal amount of time and will self destruct.
Using an 8 Ohm speaker draws less power than a 6 Ohm speaker.
Connecting speakers in parallel; results in the impedance beingreduced. For example two 8 Ohm speakers in parallel will result
in a 4 Ohm impedance load but in series will be 16 Ohms.
Incidentally the the .1 (5.1) is the sub woofer which only has
to handle the bass frequencies, a small percentage of the
amplifiers overall frequency response..
Connect your speakers and then power up the amp last
after double checking there are no shorts on the speaker
cables.
All the very best from Vintie.

No center channel sound on my Yamaha receiver


Is the center channel amp blown? How about checking the center channel input wire for signal?

Onkyo 5010 amp. Blue light went out in front and sound stop coming out. I clicked the power button and a click occurs inside the unit like its powering up but still no light or sound coming from amp.


This is either you have something loose as in a connection at the back, or the output transistors/IC are open circuit.

Wailing sound when 1971 seeburg juke box is started


I amnot very familiar with Seeburgs but the trip switch activates at the end of the record playing and THAT mutes the amp. The amp should also be muted until the tone arm lands on the record. So I would suggest the problem is in the amp.
