Replacing the LED panel where the numbers appear should solve your problem of the unit not powering on.
That LED panel is where the software is loaded and basically controls the amplifier. If you have gone through a power outage or a brown out, replacing the LED should do the trick.
You can call us at 1-866-367-9869 to order the part via a credit card. It is $30.00 shipped and there will be a pre-paid Post Office shipping label in the box for sending the faulty LED back to us. When we receive the faulty LED back, we will refund you the $10.00 that you paid for the new one.
Below is a video showing the LED replacement process from start to finish. It‘s about 4-5 minutes long and will open and play with any type of media player you happen to use on your computer.
If you have a 555 or 580 please have the serial number ready located on the back panel of the ZVOX.
