No sound out of speakers diagnostic button does not produce test tone,and right main speaker control flashes PROLOGIC. I have heard the motorboat sound coming from the subwoofer,but no sound now,green power led is on

Here is a guide to the sounds on a computer
the drivers might have been corrupted by something foreign or you might have got a virus run your antivrus program
if your computer came with a motherboard disc the sound drivers could be on it
you might have to uninstall then reinstall both the sound drivers and the sound card make sure you have both of these devices backed up to a disc before uninstalling
a yellow? question mark means you need to install/update driver to do this
right click to install driver also
click start control panel administrive tools computer management device manager scroll to sound,video and game controllers you might see a yellow question mark? Right click to reinstall drivers
click start control panel sounds and audio,volume,advanced,speakers select appropriate speakers also audio you will find 3 drop down lists make sure you have made the correct adjustments there

click start control panel sounds and audio devices you can adjust the volume there also select speaker volume you can make adjustments there you can also tick in the box place icon in taskbar

Entering ACM Self-Diagnostic Mode.

ACM (Audio Control Module) Self-Diagnostic Mode
NOTE: To enter the Speaker Walk-Around Test or ACM self-diagnostic mode, the ACM must be turned on and in radio tuner mode (AM/FM).
ACM self-diagnostic mode can only be entered while in the Speaker Walk-Around Test.

1. To enter the Speaker Walk-Around Test, press the ACM Preset Buttons 3 and 6 simultaneously.

1. The Speaker Walk-Around Test stops at each speaker and applies a different tone to each speaker for about 1-2 seconds. Each speaker is tested and displayed on the ACM in the following sequence: RF, LF, LR, RR, SUBWOOFER I, SUBWOOFER II.

1. The Speaker Walk-Around Test automatically continues and tests:

• the antenna and displays ANTENNA II, for five seconds.
• for a speaker short. If a short is present, SPKR SHORT will be displayed.
• for the CD/DJ. The ACM display will show NO DJ if not present. The Speaker Walk-Around Test will end and the ACM will return to its previous setting.

1. ACM self-diagnostic mode has five tests available:

• Preset button 1 = Audio internal/external SELF TEST. If SELF FAIL is displayed, press TUNE > to scroll view the DTCs stored. Refer to the ACM Diagnostic Trouble Codes (DTC) Index. If the system is OK, SELF PASS is displayed.
• Preset button 2 = View/Clear continuous diagnostic trouble codes (DTCs). NO DTCS is displayed if no DTCs are retrieved. If DTCS FOUND is displayed, press TUNE > button to view the DTCs retrieved. Refer to the ACM DTC Index. To clear all DTCs, press the EJECT button. DTCS CLEAR will be displayed.
• Preset button 3 = SIGNAL TEST. This test measures the average strength at the current tuner setting.
• Preset button 4 = Software configuration level. This test queries each radio system controller for the software configuration level. SOFT LEVELS will be displayed upon completion of the query. Press TUNE > to scroll view the software configuration version level.

• Preset button 5 = DISPLAY TEST. This test will light all the ACM display segments for five seconds, then turn all segments off. When the test is complete, DISPLAY TEST is displayed on the bezel.

1. To enter these tests, press the preset button desired while in the Speaker Walk-Around Test. This will abort the Speaker Walk-Around Test and start the selected test.

1. To exit ACM self-diagnostic mode, turn the ignition switch or ACM OFF.

1. If the concern remains and the fault is not detected, proceed to Symptom Chart to continue diagnostics.

the module is under the floor console. Do you have the phone user manual.

There should be a botton on the receiver that say for example, Speaker A, Speaker B, Speaker A B witch would be all of them, if your refering to surround sound try the Prologic

1-make a reset to your system.2-repeat your speaker setup.3-confirm that you assign your sysem for 5 chanell surround system.-4-change the cables between left and right front speakers if the trouble go to left channel you will have a problem in receiver itself-if the problem exict you will have a problem in speaker itself(cable or speaker)

The Denon 2500 was one of the best ProLogic receivers built, it was a work horse and very little ever went wrong with them.
To make sure you're only supposed to hear right & left speakers, press the Stereo button on the remote. Also recheck your speaker connections - this is the single most overlooked connection problem folks have.
Check the balance control to make sure it's in the center position

Make sure the Tape Monitor is not engaged.

Then, check to make sure that the Pre-Out, Main-In jumpers are connected properly on the rear panel.
If that is not the problem, try pressing the Tone Direct button on the remote (aka Tone Defeat on the front panel).

Hey there Subaquakid, the nature of surround systems is to identify separate extra channels of information and send them to the right address, being the selected speaker. In order for the rear speakers to work they need to be sent a signal. The media which you are using may not have the rear channel encoded. therefore the rear speakers have nothing to announce. Please ensure your source cd has the suround feature encoded. Hope this helps. Good Luck!
