Q: Has anyone get a high pitch sound and no signal or led indicators?

Dear Tom, According to our testing and using experience,your black mamaba was burnt already;so there is high pitch sound and no channel changing and no indicator working and no powering up function.Blakc mamaba MUST be fixed with antennas first,then you can connect power for it,otherwise it will be damaged right away,very very soon,because of its most powerful 2000mW power.Hope this can help you.
