What to do if my T+A Amplifier has no output signal and the red LED is flashing?

If there's no sound from your loudspeakers and the red LED on the screen of your T+A Amplifier is flashing, it indicates the PROTECTION circuit has been activated due to overheating or overloading. First, reduce the volume and wait about 20 seconds to see if the unit recovers. If it doesn't, let the amplifier cool down for a few minutes. Also, inspect the speaker leads and terminals for any short-circuits, ensuring wire ends are neatly twisted and replacing any damaged cables. Finally, disconnect the input cable to check for overloading due to poor earth contact; if the amplifier restarts, examine and replace the input lead if necessary.
