SB1 surround drops out immediately after power up then occasionally red light flashes on, HELP

I have a 2016 SB1 surround bar. It's was working fine then sound stop. Pulled out power and optical. Rep lugged both cables. It powers up sound starts with volume lights lighting up. Then it starts flashing then drops out. Then every 5 mins or so the Red light flashs up then disappear.

Does anyone have a solution to this?
