Troubleshooting chart Many potential problems can be resolved by the owner without calling a service technician. If something is wrong with this product, check the following before calling your authorized SHARP dealer or service center. General Symptom Possible cause ● No sound is heard. ● Is the input signal (selection) set properly? ● Is HDMI compliant equipment being used? ● Is the HDMI cable connected correctly? ● Is the HDMI cable of the correct type being used? (with ARC) ● Does the sound input support PCM signal? ● Do not connect or disconnect an HDMI cable while power is on. This may lead to operation problems. ● Noise is heard during playback. ● Move the speaker away from any computers or mobile phones. ● The power is not turned on. ● Is the unit unplugged? ● The protection circuit may be activated. Unplug and plug in the power cord again after 5 minutes or more. ● Volume cannot be controlled. ● Check if the HDMI CEC is enabled. ● For headphone or RCA, TV setting (VARIABLE) is required. ● 3D images not displayed on the TV. ● Depending on the TV and Video component, 3D images may not be displayed. Check the operation manual of the respective component. ● Background noise appears when connecting with headphone output of TV-Terminal. ● Please change to HDMI/ ARC or RCA-Output terminal from TV-Set. This effect may occur depending on your used TV-Brand, model and age, and it is not the sound bar problem! Condensation Sudden temperature changes, storage or operation in an extremely humid environment may cause condensation inside the cabinet. Condensation can cause the unit to malfunction. If this happens, leave the power on until normal playback is possible (about 1 hour). Wipe off any condensation on the transmitter with a soft cloth before operating the unit. If problem occurs during operation When this product is subject to strong external interference (mechanical shock, excessive static electricity, abnormal supply voltage due to lightning, etc.) or if it is operated incorrectly, it may malfunction. If the unit is not restored in the previous operation, unplug and plug in the unit again or unplug all component connected and plug in again. Maintenance Cleaning the cabinet Periodically wipe the cabinet with a soft cloth. Caution: ● Do not use chemicals for cleaning (gasoline, paint thinner, etc.).
