My Marantz SR7300 receiver will not turn on. When I plug it in I hear a relay click but nothing else. Internal fuse is ok, nothing appears smoked.

It is probably shorted out. the fact that you hear a relay click is bad news for you. Take it in and tell them that you cannot get power from the switch through to the main board.

Mod 2245 marantz no sound right or left.


Hello,

Do you hear the relay click when you turn the unit on? If not you have a issue with one or both amps. If you do get a relay click, check your pre-amp out/main amp in connections on the back. You may want to also play with your controls, dirty controls can cause this condition as well. If you would like to have the unit serviced, check out my website, I have a lot of experience with the vintage Marantz units.

Thanks

Marantz SR 3001 won't turn on


Check for shorted speaker wires - if none found, disconnect speaker / select headphones and see if you hear music thru the headphones. If not - you may have burnt out power transistors, etc.

Audio Receiver only makes one "Clicking" sound when I push the power button


Definitely sounds like a relay... How old is your unit? Sometimes they get stuck and need a good cleaning with DeOxit. Good luck!

Plugged marantz sr8100 into 230V outlet without transformer. Did this likely cause irreparable harm to receiver?


Hello
If you have plugged in to 230AC with voltage settings was 110VAC, the transformer has been damaged already [opend winding]. If the voltage settings was 230VAC itself, there will be no harm to its internal transformer. Anyway, open it, anc check the fuses. In some cases, fule only will blow out, preventing from furhter damages. I'm not sure about it, but check it. If the fuse only has blown out, and there has no harm; you are lucky I should say. OK.

Just picked up a Marantz SR-19, Everything looks like it works but I get No sound out of it. Unfortunately, there is NO remote and was wondering if there is a setting like Mute or a speaker select on the...


A Mute indicator would tell you if it was muted. Make sure no Tape or Multichannel Input are selected by mistake.

There are supposed to be jumpers across the Pre_Outs to Main In's in the back when you're NOT using external amps. You could substitute short RCA cables.

I have a Marantz SR5500 and the unit will not stay powered on.


I have this problem. it is caused by an o/c mains transformer primary winding. the clicking and flashing light is the stanbyy circuit trying to switch the power on to the main (large) transformer when it gets no voltage out it switches back off

One speaker channel is crackly.


There is Definately a Short in the Amp if tapping Fixes it. Could try opening the amp and Inspecting the Back side of the Terminals. You can use a Voltometer and check the Wiring inside. Turn off Power Before doing this!

Marantz CDR631 is dead


open it up and take the mechanism out, then you should see a servo PCB screwed to the underside of the mechanism.
unscrew this and where the connecting wires plug in from the main PCB, you should see 2 or 3 fuses which look a bit like capacitors and should be red in colour marked MPXXX eg. MP100?
replace these if you can find spares, if not bridge them with a bit of thin wire soldered in place and then it should switch on once reassembled.
the clicking sound you mention will be the main power supply capacitors running and this is normal.

Powers off after about a second


If it smoked, it's NOT a fuse!! :o The output transistors are blown and must be serviced by a shop. Expect $50-$150 for that repair.
