another possible issue is the muting circuit
aside from power supply
i've seen these kind of problems sa ibang mga brand

sayang nahuli ako...

kung dumaan iyan sa ibang tech sis triac.. pwede jinumper ng dating tech ang contact point ng Relay.. kaya ganyan ang effect..
or kung hindi naman human made iyan..
tiyak naka actuate/naka on mode lagi ang Relay Mo..
ang purpose kasi ng relay ckt na iyan ay para sa power delay.. pampa delay ng connection sa seaker line out... isa pa sa purpose niya ay para DC out detection... para autromatic mag protect ang unit kung may DC binabato ang amp sect para protectionan ang speaker na wag masunog..

nakalimutan ko anong tamang technical term dyan sa tok sound na yan...

si Sis danica alam iyan ^_^

sa may Spkr out malapit iyan.. may relay dyan na magka cut sa line path nila.. check mo baka naka actuate/naka on lagi ang relay..
Double check mga ecap malapit sa relay yan kasi ang isa sa pampadelay ng actuation niya
