Question about Marantz SR-4300 Receiver

Standby Problem Hi, My amp has just suddenly started going to standby and needs to be powered off to bring it back on. I have been through several very hot summers with no problems, but now it suddenly seems to be over-heating or something and shutting off, it is about 26 deg C here at the mo. Any thoughts on what I may need to replace / fix or is it just too hot for it?? Thanks

    I have teh same issue with this Amp, but it is no where as hot here. Is it a temperature issue? The map stays on for about 15 mins then goes to standby



    Thanks Rob

Hi,problem could be due to some voltage fl,or any component failure or may be due to the wrong connection of speakers. First check the speaker wiring,if it is ok then better to consult a professional service person. Set goes to standby means the protection circuit is turned on, normally any component failure or short circuit happens inside the amp, systems will automatically detect it and to protect it from any further damage, turns to standby.

No, I think you have a bias problem in the audio output circuit of this receiver. There is really not a lot a user can do to fix this unless you have the electronic know how and know how to trouble shoot solid state electronics. Good Luck

Sound stops suddenly


Alright, so wait, explain that again, It stops working when your using it, or when it goes into standby?

It starts working again after what? When you come out of standby?

When going into standby, the system goes on low power may cut the power to your speakers.

Check your Power settings.

RIGHT CLICK on DESKTOP> Select properties, Go to screen saver Tab and click on the Power button, then check all the power options such as when it goes into standby, how long till it does and adjust them to your preferences, also make sure Hibernation is turned off as well, when it goes into Hubernation, it cuts almost everything.

Give this a try and let me know,
good luck

This is usually an indication of a failure in the scan amplifier sections. When the scan amplifiers or high voltage sections fail, the main power supply will usually also require servicing.

It is very common that the fly-back and high voltage multiplier and also the horizontal output stage fails in these sets. Along with it, the power supply will usually require to be serviced. On rare occasions, the vertical deflection amp fails.

Standby light is a signal indicating a voltage trouble on your system . It could mean a compoment is defective or a power regulator needs replacement worse is a system IC replacing. you better bring your stuff to a Sony service center and do a check on your TV system.
