No! there is a problem in the audio output ic's "more than likely shorted parts" check to make sure there are no shorts in the speaker wiring, if okay! I'am afraid it is bad outputs.

The audio output stage has a load causing the auto protect to kick in. First check speaker wires for shorts, if okay it is the above mentioned.

Re:"* It looks like the CPU is forcing the receiver into standby every second or so (_standby voltage to power board alternates between 5v and 0v. as measured on the ribon wire), * the clicking relay is on the standby board, there is no display when relay is clicking"

That is standard protect mode. When a problem, like a wrong voltage or a short is detected from CPU, the system is forced to standby. The clicking noise is the safety switch forced by CPU every tot seconds. there will be no operations apart standby when in protect mode. The CPU higher voltages get shut down to prevent further damage, only low +5V is kept on to show the diagnostic protect mode. The clicking is just a signal that there is a fault, and not the fault itself.

Re:"EXCEPT when multi button is pushed, then clicking stops and I can see display"

That is a better hint on what the fault could be. On multi room different speakers are used. start checking speakers connection, focus on the speakers that are eventually not used in multi room.

If speakers connections are OK, concentrate on terminal block (input output) circuits, chck the surround mode selector. Testing is mainly done at component level, ensuring that there are no shorts to chassis, cold solder joints (broken ternminal contacts), or faulty components in this areas.

Since the fault is not ocurring when in multi room mode, you can for example exclude circuits like power supply transformer and video board (if present), that are not affected from changing to multi room mode.

If there is no error in there the following troubleshooting will be on the complex audio section (from preamps to power amp final and terminal).

About not getting into service mode, that would be quite unusual. When a marantz is on protect, it still goes in service mode and displays PROTECT at start.
I do not have the manual for SR8500, but you can follow instructions on how to get in service mode from page 32 on the manual for SR4400, uploaded here.

That is a Common Message on this Model. The only User Fixable Option is to Try and Reset it.which is activated by simultaneously pressing the Speakers A/B button and the button on the front panel while the power is on. Just keep them pressed until it finishes cycling through the reset and returns to normal.

Let me know, if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

DVD should be connected to an input on your tv not the monitor out.

Check the speakers impedance. it should be greater then 6ohm otherwise you overload the system. Also, if the speaker sytem is rated (in Watts) below the amplifier's power it overloads the amp at higher volumes.

Check the settings on your dvd player!. It might be set to PCM
instead of HDMI.

You may not be using an active input to test. Try attaching an fm antenna and using the tuner. Sone inputs are set to digial and will not make sound with the analog input. The input selector does turn it on. Saves a step.

Order the manual directly from Marantz.

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

A high quality fast response Servo Stabilizer will solve the problem but mark my words highlighted

Hello Meredith, for what you are saying, you could have a problem in the cable that you use to send the signal you want to record, or the microphone cable or the line cable
put to record the Marantz, without any cable connected to the inputs and listen with the headphones, if the hum is, if not, try to change the cables for others of the same type, if you use microphone, controls the connectors, which do not have humidity or rust in the contacts
I hope you can solve the problem
Greetings Franco Dosil

Hola Meredith, por lo que comentas, podrias tener un problema en el cable que utilizas para enviar la se?al que quieres grabar, o el cable de micr?fono o el cable de linea
pon a grabar el Marantz, sin ning?n cable conectado en las entradas y escucha con los auriculares, si el zumbido esta, si no esta, prueba cambiar los cables por otros del mismo tipo, si usas micr?fono, controla los conectores, que no tengan humedad u oxido en los contactos
Espero que puedas resolver el problema
Saludos Franco Dosil
