Question about Pioneer VSX-504 Receiver
Had to initialize the microprocessor. Since doing that can't access the system setup menu. Worked fine before the initialization. operating instruction are no help. Everything else works fine. Any help is welcome.
Hope this helps,You may also be able to find more info,Here
1) WHEN DO I "INITIALIZE THE MICROPROCESSOR" AND WHY?
You’ll rarely need to "initialize the microprocessor" under normal operating conditions. In a few cases, the microprocessor will temporarily freeze or "lock up" just as your home computer does. When this happens, just follow the guidelines in the back of your owner’s manual to "unlock" the microprocessor and restore normal operation. (This is directly comparable to rebooting your computer. It’s an electronic wake up call to your unit’s temporarily paralyzed microprocessor "brain.")
If you experience some unusual behavior -- a channel that’s suddenly silent, "forgotten" level adjustments, some eccentricities in your unit’s Personal Memory Plus system, etc. -- you may need to reset the microprocessor. Of course, you should check all connections carefully first. But if you’ve eliminated these items as a source of potential problems, you may need to go through the initialization process.)
initialization is easy. For the AVR-3600 and AVR-5600 receivers, for example, just turn the unit off with the front panel power switch. Then press and hold both the "AC-3 RF" and "Phono" simultaneously while you turn the unit back on. (Use the same front panel power switch.) That’s all that’s involved.
What causes these problems? Several things can -- a jolt of static electricity, a current surge through an antenna input, etc. But don’t worry, the microprocessor is well shielded from any permanent effects.
When you do initialize the microprocessor, remember that this erases any setup instructions you may have previously programmed into the unit. However, the on-screen menu will quickly get you through a new setup. And, if you write down your preferred settings BEFORE you reset your unit’s microprocessor, you’ll have an even easier job!
2) DO I ALWAYS HAVE TO "TOGGLE" OR "PAGE THROUGH" THE ENTIRE MENU WITH THE ON-SCREEN DISPLAY BUTTON, EVEN IF I ONLY WANT TO SEE THE FIRST PAGE?
Of course not. Just press "Mute" twice and the on-screen menu will disappear!
When you press the remote control’s "On Screen" button, the on-screen menu appears. Most times, you’ll probably want to page through the menu to look for a particular setting and subsequent pushes of the "On Screen" button make that easy -- every time you press it, you find yourself looking at a new menu page.
However, there may be times when you just want to check the menu’s first page and it’s annoying to have to scroll through all the menu’s pages just to get to the end. To avoid this, just press the remote’s "Mute" button and the menu will disappear! However, you’re now in mute mode so you need to press the "Mute" button once more to restore your previous volume setting.
Easy, wasn’t it?
15) CAN I PROGRAM MY REMOTE CONTROL TO SEND MACROS (MULTIPLE COMMANDS ) WITH THE TOUCH OF ONE BUTTON?
Yes, you can. DENON remotes are fully macro-capable. If you’ll look closely at the top of your remote controller, you’ll see a "System Call" section (usually differentiated by three pale green buttons marked "Set," "One," and "Two.") These buttons allow you to program a sequence of up to ten different commands and assign that sequence to either of the two "macro memories" for easy one-button recall. For more detailed information, see the Owners’ Manual for the unit you’re interested in. 17) WHEN THE "PROTECTION" INDICATOR COMES ON THE DISPLAY PANEL OF MY DENON RECEIVER, DOES THAT MEAN IT NEEDS TO BE REPAIRED?
Most probably not.
The "Protection" light comes on when the receiver’s current sensing and thermal monitors detect some unusual operating condition that, if left unchecked, might damage the amplifier. The sensors disconnect the amplifier from the speakers by switching the high speed output relays "off." This can happen, for example, if there’s a dead short in a speaker wire, or if you’re using very low impedance loudspeakers at high volume for an extended length of time.
In most cases, the circuitry will automatically reset after a few moments and the Protection indicator will go out.
If the Protection indicator does not go out, or if it goes on immediately after you turn on the receiver check your loudspeaker connections to make sure no wires have inadvertently shorted.
If, after checking all your connections, the Protection indicator stays lighted, you may need to "initialize the microprocessor" (see the FAQ on that topic) or take your receiver to an authorized repair center for a checkup. Run through the reinitializing process first -- it’s easy to do at home without disconnecting the entire system.
18) I OCCASIONALLY SEE AN "OVERLOAD" INDICATOR ON THE FRONT PANEL DISPLAY. IS THIS THE SAME AS "PROTECTION"?
No it isn’t. Some DENON components have a front panel "Overload" indicator that tells you when you need to decrease the sensitivity of a particular analog input. Simply follow the directions under "Analog Input Level" to assure distortion-free operation that won’t continuously trigger the "Overload" indicator.

Do you have the manual? I downloaded earlier when I was going to reply to you.
Let me know if you need it as I have not been able to apply my time to help you, and I can forward it to you. There is something in it about resetting and setup.

Initialize the microprocessor or system control is called RESET process and after reset unit goes to factory default settings.
I think this unit has not been reset properly. Please initialize it again then unplug unit for couple of minutes and replug in AC and check.
