Marantz AV550 problem

My marantz av550 pre amp keeps cutting out and when I turn it back on it buzzes loudly inside the pre amp and through the speakers.

    After the buzzing stops the audio goes on and off repeatedly at a very low level. I have to turn it way up to hear anything.

  • ssryan2 Jan 28, 2009

    I don't see any loose wires or bad solder. It is a really loud noise that starts when i power it up and lasts about 3 seconds. there is the initial click, then the buzz and then nothing. there should be another click i think.
    any help is appreciated.

Hi and welcome to FixYa,

The only possible source of the buzzing sound in a pre-amp would be relay(s). Since there are no high power components, this could either be a faulty relay trigger transistor or leaky capacitor either in the power supply circuit of the pre-amp or mainboard. It is also possible that other connectors could be loose and/or cold solder issues. Best approach would be to open the unit up for a look & see.

Good luck and thank you for using FixYa.

Check you fuse resistance with an ohmeter. Also check for any loose or broken wires and solder pieces. It is possble you could have positive and negative wires on backwords in your speakers? I would check speaker wiring as well

    sounds like one of your resistors or transforemers have burnt out.

    the powersupply could be bad. when they start to go they usually send a higher voltage than they were designed to

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

Willie

Marantz NR1402 AV receiver Going to standby Mode


There could be a short in one (or more) of the speaker connections. Try disconnecting all speakers and turning on the receiver. If it still switches to standby, there may be an internal problem.

How do I connect Marantz AV7005 to Marantz SR9600


Remove the little black jumpers on the 9600 that link the pre amp section to the main amplifier inputs. They are the top row of rca inputs on the back. Using single rca cables from the pre out of the 7005 into the main amplifier of the 9600 connect all the channels you have wired speakers for, L,R,C, SL,SR, etc up to 7. Connect all your sources to the 7005 with whatever cables you have it doesn't matter. Turn off the 9600 volume and use only the 7005 to control the volume. It works perfectly giving an awesome amp a new lease on life. Good luck!

Marantz SR9200 shuts off intermittently while watching or listining.


Check all speaker connections. unplug everything.. start with just L and R speakers. Do a mic calibration..also check all your source inputs to the amp. start from the basics. Is the amp still under factory warranty? I used to install marantz...also make sure unit is well ventilated. IF you are using audio zones in your place..with in wall volume controls..make sure they are impedance matched. VOLUME may be set to high...overdriving the outputs..eventhough audio may not be loud. Set volume to -30...?

Most likley, if I'm right, you have heard some staitcy, crackly noises, accompanied with this failure. If so, the problem is without a doubt on the D.S.P. board, witch is the one with the optical jacks on it, The culprits would then be I.C. 719 & I.C. 720. This is a common problem with this model, and the sr6200 & 5200 as well. A low tech method to confirm this is to touch IC 720 (the smaller one) while it's on. If you can keep your fingertip on it for at least ten seconds, it's ok, and the problem is elsewhere. If not, (IT WILL BE VERY HOT) the the board must be removed (27 screws from left to right) and replace BOTH IC719 & IC720.
