I HAVE A MARANTZ SR880. WHEN I SWITCH IT ON, IT STAYS ON STANDBY MODE. WHEN I SELECT INPUT, IT CLICKS AND THE STANDBY LIGHT FLICKERS. WHAT DO I NEED TO DO?


Hi,
Possibilities for dry soldering. its a Common problem with this model. Also can happen because of aging . Its tedous procees to open and repair the av receivers. Its better to find expert who can do it for you. i think Marantz authorized service center will not do this as its an out dated model .

If you are using AV cables from your TV for movies and a different hookup for the X-Box would explain that the relay for the sound inside your unit may have blown from being overloaded or faulty. Should be an easy fix at a trusted electronic service place.I am not sure if your system has a manual reset button underneath or on back, but you could look for a tiny hole with reset on it or a red button. It may save you a trip to the doc.

Switch off the unit. Then hold down Sorround, Exit, Memory & Clear buttons all together and then switch on the power. This should work.

We have a Marantz sr4500, everytime we put it on it makes a Zzzzzz sound and then it turns off with a loud "buk" sound and shows protect on the amp's screen, after few seconds the amp turns...


It is not so easy to probe into to find a protection fault condition. The fault can be your output drivers- the MOSFETS/IC's fitted for both the channels, Use a meter after disconnecting to check for short in the drivers. Disconnect the positive and negative voltages to the output and see if the protect changes. Even a fault in the preamp stages that drives in high current into the output can shut the Amplifier. Sometimes this can be a noise like a HUM or HISS before the protect works. Faulty capacitors in these circuits also can cause similar issues and needs close observation.In this case I think that some capacitors are faulty as when the set is put on it charges on to make the amplifier work. Possible fault in the protect circuit or preamp.
You need to confirm and replace the specific stages or outputs. If not there can be issues in the mother board, maybe the protect circuit by itself is shutting off due to a faulty bias , maybe a leak in any voltage/current sensing circuit. Also disconnect the speakers and test, if the protect is off then check for short on the speakers.
