Red/green flashing power on LED
Older model VTF-3 HO


About a month ago the power on LED started flashing on/off. At the same time a sound similar to a heartbeat was heard coming from the sub.


Looking for troubleshooting help.



TIA for any help

Yes, thank for calling back.


You're recommendation was to pull out the amp and verify that all connections are seated properly; speaker wires, ribbon cable, etc. Do a visual inspection to see if any solder joints are OK, no cracks, etc. Reinstall and test again. If issue persists send it in.
