What to do if my JBL SDP-55 Recording Equipment unit responds erratically to the remote control?
If the unit responds erratically or not at all to the remote control, ensure there are fresh batteries in the remote control. Also, check that the front panel window is visible and you are pointing the remote control towards it.
Why is there no sound coming from my JBL Recording Equipment?
If no sound is being produced, ensure that the correct input has been selected and the ‘audio source’ has been set correctly in the ‘input config.’ menu. Check that the source equipment is on, is operating normally, and is in ‘play’ mode if appropriate. Also, verify that the volume is turned up to a reasonable level and the receiver is not in mute mode.
What to do if sound only comes from some of the speakers of my JBL SDP-55?
If sound only comes from some of the speakers, ensure that you have an appropriate surround source selected and playing. Check that the BD/DVD disc is encoded in the appropriate format, and the correct format has been selected in the disc start menu of the BD player (if applicable). Verify that the BD/DVD player has been set to output ‘bitstream’ audio on the digital output. Ensure the display window indicates that the disc you are playing is a multichannel recording. Confirm that all the speakers are correctly connected to the speaker terminals and are secure. Ensure that you have not selected ‘stereo’ as the decoding mode, your speaker balance is correct, and you have configured the receiver to include all the speakers in your system.
What to do if my JBL SDP-55 Recording Equipment has poor or distorted sound?
If the sound is poor or distorted, ensure that you have not excessively increased the input sensitivity (i.e., reduced the maximum input signal voltage) in the input config. menu if an analog input is being used. Also, verify that you have selected the correct size of speakers to suit your system in the setup menu.
How to fix no picture on JBL SDP-55 Recording Equipment?
If no picture is being produced, ensure that your viewing device is turned on and switched to display your receiver. Test by pressing the button on the receiver or on the remote and look for the main menu screen on your display device. Verify that the correct video input is selected on the receiver and that the video source is on, is operating normally, and is in ‘play’ mode if appropriate.
Why can't I select Dolby or DTS decoding modes on my JBL SDP-55?
The receiver can only apply Dolby and DTS decoding to sources which have been encoded in the same format. Check that a digital source is selected and connected. Ensure that the source is playing appropriately encoded material, that the BD/DVD disc is encoded in the appropriate format, and that the correct format has been selected in the disc start menu of the BD player (if applicable). Also, verify that the BD/DVD player has been set to output ‘bitstream’ audio on the digital output.
How to fix bright edges or ghosts on the picture of my JBL Recording Equipment?
If there are bright edges or ‘ghosts’ on the picture, ensure the ‘sharpness’ control on your display device is switched off or set to near minimum. For HDMI connections, try using a shorter cable or alternatively a different brand.
Why does my JBL Recording Equipment AV selects Dolby Surround when playing a Dolby BD/DVD?
If, when playing a Dolby BD/DVD, the AV selects Dolby Surround, ensure that you have a digital connection from your BD/DVD player. Sometimes Dolby BD/DVD discs contain material at either the beginning or the end of the main movie that is not in full 5.1 Format, but in two-channel.
What to do if there are no lights on my JBL Recording Equipment unit?
If there are no lights on the unit, ensure the power cord is plugged into the receiver and into the AC power outlet, and that the power button is pressed in. If a red LED is present, the receiver is in standby mode. Press any button on the front panel or the standby button on the remote control.
