My cable box say e007

Have you contacted the cable company? It's their equipment that you pay each month to use why trying to fix it?

Not sure if it's fixable without replacing, does it have an option to flash firmware on it? Maybe try updated firmware. From the comments about this error, even if the error goes away, there is no sound from the box anymore.
