Troubleshooting-Continued Amp Symptom Possible cause Remedy A low-frequency noise or hum can be heard? The audio connecting cables at the rear of the TX-SR501/TX-SR501E are too close to the power cord. Untangle the audio cables and position them as far away as possible from the power cord. The sound is too bright or harsh and the high range is The Treble function is set too high. not clear. Adjust the Treble function (pages 29, 37). The subwoofer mode is set to OFF or is set incorrectly. Check the subwoofer mode (page 25). The subwoofer is not working or is very quiet? The volume of the subwoofer is set at minimum. Subwoofer output depends on the source material. Some material may not use the subwoofer much. Check the volume of the subwoofer (page 27). The TV's input selector is set incorrectly. Select the correct input on the TV (i.e., the input to which the TX-SR501/TX-SR501E is connected). The video cable is not connected properly. Check your video cables and connections (pages 10-19). There's no picture on the TV or monitor? The video input and output are different formats. The TX-SR501/TX-SR501E doesn't convert between video formats. It works as a video signal switcher. Composite video input signals are output only by composite video outputs. S-Video input signals are output only by S-Video outputs. And component video input signals are output only by component video outputs. Can't hear an AV component? The wrong input source is selected. Select the correct input source (page 28). The wrong remote controller mode is selected. Select the correct mode (page 9). There are no batteries in the remote controller. Install new batteries (page 5). The batteries are flat. Replace with new batteries (page 5). The batteries are installed incorrectly. Check the batteries and correct as necessary (page 5). The buttons on the TX-SR501/TX-SR501E work OK but those on the remote controller don't? You're not pointing the remote controller at the Point the remote controller at the TX-SR501/ TX-SR501/TX-SR501E's remote sensor. TX-SR501E's remote sensor (page 5). You're too far away from the TX-SR501/ TX-SR501E. Use the remote controller closer to the TX-SR501/ TX-SR501E (page 5). The remote controller has a range of approximately 16 ft. (5 meters). A strong light source is interfering with the TX-SR501/TX-SR501E's remote sensor. Make sure that the TX-SR501/TX-SR501E is not subjected to direct sunshine or inverter-type fluorescent lights. Relocate if necessary. If the TX-SR501/TX-SR501E is installed in a cabinet with colored glass doors, the remote controller may not work reliably when the doors are closed. Open the doors, or use a cabinet without colored glass. Try entering the code again (page 41). The wrong manufacturer's code has been entered. If more than one code is provided, try them all (page 41). With some manufacturer's AV components, certain buttons will not work as expected. Can't use the remote controller with other AV components? You're pointing the remote controller at the wrong AV component. To control an AV component connected via , point the remote controller at the TX-SR501/ TX-SR501E. To control an AV component that's not connected via , point the remote controller at that AV component (pages 40, 42) You've made an connection but not an analog RCA/phono connection. To use , you must make an connection and an analog RCA/phono connection between the AV component and TX-SR501/TX-SR501E, even if they are connected digitally (page 19). Remote controller 46
