I have the same problem. I turn on the stereo in my boat and the amp has three blinking lights and there is no sound. It seems to work randomly. But more on the not working side? please help...

    No sound output from my JBL Cinema SB400, tried Bluetooth and HDMI also optical. It was fine yesterday and I turn it on and just no sound what so ever. Can anyone help?


    Does the power light come on? If not, check the power cord and power outlet on the wall. Maybe plug in a table lamp to the wall power outlet to make sure the outlet is working. If the power light is on, check the Mute button on your JBL remote control. Also check the Mute button on your TV if sound and picture go through the TV first.
    We had a Harman Kardon soundbar (model SB30) made by the same company as your JBL. It worked great for a few months. Then there were a couple of funny high-pitched sounds that stopped when we turned the soundbar off and back on. Then a day or two later we truned on the soundbar and it was completely dead - no sound at all. Harmon/JBL replaced the soundbar under warranty with a refurbished one which lasted about two weeks and dies the same as the first one. Finally, they replaced the second one with a higher model (the SB35) which is still working, although it occasionally makes a rapid clicking noise for a moment here & there.

    This indicates that the Blue tooth pairing with the already paired device has been reset and the JBL Flip is ready for pairing with new device. This position, red and blue blinking, can be obtained by long pressing the power buton.

    Red and blue light flash on and off


    ITS IN PROTECT MODE. EITHER ITS BLOWN OR THE SUB IS TRYING TO PULL TOO MUCH POWER. UNHOOK THE SUB AND SEE WHAT HAPPENS IF THE LIGHTS STILL BLINK THEN AMP IS BLOWN. IF THEY STOP BLINKING AND ONLY ONE STAYS ON THEN LOWER THE SETTINGS ON THE AMP AND TURN THE BASS AND VOLUME DOWN ON THE DECK TO LOWER THE AMOUNT OF POWER BEING PULLED FROM THE AMP.
