Check proper connection to output stage(good condition of speakers cables)no short in cables or touching each other.-no problem in speaker itself(speaker coil short circuit or open circuit)-disconnect all from amp and check if it is ok-you will have a problem in cables or speaker if not you will have a problem in your amp.

There's a problem with the amplifier transistors or other heat generating circuit. That's what triggers the overload light.

We have a Optimus STAV-3770 that is stuck on 'Muting'. Have tried everything we can think of to no avail. Even purchased a new remote.Is there a solution.


Switch off the mains supply before connecting/disconnecting any cables.

Disconnect all the speaker cables and switch on. If the fault clears carefully check the speaker wiring for shorts before reconnecting.

If the fault is not in the speaker wiring or speakers the amplifier will need expert attention. Faulty speaker wiring can easily damage solid state amplifiers.

Loud thump when turning of at switch


This is COMMON for consumer electronics. The amplifier goes out of balance during power loss. Fancy high power units have a relay which instanly disconnects the speaker when power is removed.

Amp Power light will not go on. Protection light is lit- Thump sound in speakers


It probably has shorted output transistors. To eliminate other possible causes, read through the following page.

Keeps swirching to protect mode


First thing to do is disconnect all of the speaker wires on the amp. Turn on the amp, if it is still turning on and off then there is a definant problem in the amp circuitry. If you have no solid state service skills, I highly advise you to take the amp into a repair shop. If it stops turning on and off turn off the amp and try and connect up one speaker at a time untill the amp starts to mess up. you then take that speaker and have it checked out and inspect the wireing for pinchs or shorts.
